Builders were using big bypasses across the wipers of their regens to kill wiper noise in the 1930s, if not earlier; check the ARRL handboo This is why I don't grok the complaints about regen-pot noise; you put 0.22 to 1 uF from the wiper to ground in addition to the RF bypass. A series resistor between both bypasses helps both. If you really want to gild the lily nowadays, power the oscillator anode from an adjustable three-terminal regulator. 73, Dave Newkirk, W9VES dpnewkirk@home.com From glowbugs-owner@piobaire.mines.uidaho.edu Sun Jun 20 23:55:55 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id XAA00065 for ; Sun, 20 Jun 1999 23:55:54 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id XAA19559; Sun, 20 Jun 1999 23:49:20 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id UAA29566 for glowbugs-outgoing; Sun, 20 Jun 1999 20:40:23 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from peach.iaxs.net (root@peach.iaxs.net [209.134.128.1]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id UAA29561 for ; Sun, 20 Jun 1999 20:40:18 -0700 (PDT) Received: from citrus.iaxs.net (bill@citrus.iaxs.net [209.134.136.217]) by peach.iaxs.net (8.9.1/8.9.1) with ESMTP id WAA04445 for ; Sun, 20 Jun 1999 22:39:37 -0500 (CDT) Received: (from bill@localhost) by citrus.iaxs.net (8.9.1/8.9.1) id WAA27431 for Glowbugs@piobaire.mines.uidaho.edu; Sun, 20 Jun 1999 22:39:33 -0500 (CDT) Date: Sun, 20 Jun 1999 22:39:33 -0500 (CDT) From: Bill Hawkins Message-Id: <199906210339.WAA27431@citrus.iaxs.net> To: Glowbugs@piobaire.mines.uidaho.edu Subject: GB> Contact at WWV Fort Collins?

His answer? "I bought it for the 'mill." Is that us about regenerative receivers?

If it is just a nostalgic impulse, we might as well bid SW-3s on up to $750 or $1K , as we will never get one built that satisfies us. But if we seek to rejoin the hands-on radio of the late '20s in the form of, at least, the Eisenhower Era, lets ask: 1. Why do we even consider working an oscillator into the wire of the aerial? If you want a one-tuber you should hide a 6dB FET in the plug-in coil. 2. Why must we try for same-tube local oscillators? They are going to pull, pals. 3. Why deplete the collector's stashes of Brandes 'phones? There are lots of modern ways to off load an audio signal without even saying "op amp." Incidentally, I see great hope that we are really interested in circuitry instead of Sophistry this time.

Hello-- IIRC, the dielectric material needed to construct high-capacity (and relatively high-working-voltage) ceramic capacitors didn't get perfected until World War II. High-capacity disk caps typically use a "high k" (or high-valued dielectric constant) ceramic that's temperature-UNstable. For example, the common Z5U temperature characteristic peaks at approx +25 C and is +20 to -50 percent over temperature (+10C to +85 C). If you plot capacitance versus temperature, the curve looks somewhat parabolic, with a peak around +25 C and capacitance falling off on either side. Initial capacitance tolerance is +80 to -20 percent of nominal value. The X7R characteristic is more stable in both capacitance and temperature coefficient, but you may not find the voltage rating you need. So, if you want to use an older-vintage disk ceramic as a bypass cap, make sure that it stil provides enough capacitance at temperature extremes. Assume that any older, 600-V disk ceramic cap of value over approx. 1000 pf is of high-K construction and use accordingly. One other item: the high-K ceramics can act as acoustic transducers and will emit a ticking noise if subjected to high pulsed currents. Virtues? Well, these disk caps didn't cost much and do offer lower series inductance than most old-style wound paper caps.

I understand when to use >Ceramic disk caps (some not too stable, excellent for RF coupling and >bypass) or Mica (very stable,even more so for SM, very low loss, accurate, >expensive) or Temperature compensating caps like N750s (to correct for >the effects of temperature rise on other components) or Mylar (like the >old paper caps but more stable and low loss). I would readily use the >Mylars in place of Paper Tubulars but can't answer the question "why not >a Ceramic disk ?" It was for the shielding effect. The grid side of the cap is usually at a higher impedance than the input side, and more prone to hum pickup, so placing the outer foil side on the input (or ground) side of the circuit provided a shield for the inch or so of metal (the inner foil) that would otherwise have picked up hum. > >Also the paper caps used as bypass caps are all connected outside foil >(stripe) to ground so the outside is at a lower potential (safety ?) and >maybe for the shielding effect ?? > >73s Kees K5BCQ 73, Mike, KK6GM From glowbugs-owner@piobaire.mines.uidaho.edu Mon Jun 21 11:45:38 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id LAA00784 for ; Mon, 21 Jun 1999 11:45:38 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id LAA02736; Mon, 21 Jun 1999 11:38:55 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id IAA06798 for glowbugs-outgoing; Mon, 21 Jun 1999 08:24:45 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from weedcon1.cropsci.ncsu.edu (weedcon1.cropsci.ncsu.edu [152.1.207.51]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id IAA06793 for ; Mon, 21 Jun 1999 08:24:39 -0700 (PDT) Received: (from na4g@localhost) by weedcon1.cropsci.ncsu.edu (8.8.8/8.8.8) id LAA28082; Mon, 21 Jun 1999 11:23:13 -0400 (EDT) (envelope-from na4g) From: User Na4g Boatanchor Bob Message-Id: <199906211523.LAA28082@weedcon1.cropsci.ncsu.edu> Subject: Re: BC-186 (Was: Re: GB> what did I actually buy?

There is also > what looks like an "ANT." on-off switch. Any idea what that is for? The BC-186 is a very hot regen receiver. It uses 4 tubes, an RF stage, a detector, and two audio stages. I don't offhand remember the tubes but something like a pair of 34's and a pair of 30's rings a bell. My OM had the fortune to be in on the testing of that ``mule radio set'' back in 1932 at the Signal School, Ft. Monmonuth. He had fond memories of it, and thought it was not too bad. The companion TX uses a 40something oscillator and an unobtainum 865 tube. It is not that bad as a TX. You can sub an 801 for the 865, by switching one wire on the tube base. I had the fortune to own one of these sets and use it on FD back in 1982. It was not very competitve on 80M CW, and sitting on the ground crouched on a set of 15 inch wooden legs was not conducive to speedy operating. A 15 foot whip antenna on 80, was not conducive either. But, it was fun to knock off a few QSO's, OT style. Not in the middle of FD, it was a fun set to run. If only the receiver is available (it had a companion battery box the same size as the receiver), you will have a dickens of a time trying to find a proper plug for it...... Neat RX though, and very neat OT Mule Radio Set, combined with its TX, hand crank generator, wooden mule pack,..... and several grunts.....

The "trick dielectric" ceramic-disc condensers also exhibit changes in capacitance with applied DC across 'em, AC current through 'em, and so on and so forth. In some audio applications, they can introduce distortion; and in a filter, they're quite unpredictable. The smaller size (than a tubular paper condenser) can also complicate layout, especially in a homebrew project that's a bit "fiddly" about what wires run where. Any of those considerations could have led to the parts-spec for the HBR receiver. Subbing good tubular mylars will dodge most of 'em, and a little thought applied to the schematic & pix will get you around the rest. 73, --Bobbi KB9GKX "RJ" rbarmore@indy.net Roberta J.

I am adjusting the screen resistor in the 2E26 output stage of my AN/GRC-109 so that it will provide me with 5 watts output, and connecting a VFO made out of a 3 - 4 mHz Command transmitter. Lessee now: a 6AG7 VFO, driving the 6AC7 crystal osc stage, driving the 2E26 output stage. With all the filaments, this will be a new low in efficiency.

He wants to see how long he can pedal (!) I managed to procure (neat word, "procure") all the necessary parts for the Cycle-Gen Mark 58-1 from various places like the city dump, a bike repair company with a trailer full of parts, etc. So far, total cash outlay for the cycle conversion, including the Sears Ergonomic Exercycle with its 40 lb flywheel, has been $0.00. Heck, one of the bikes I picked up at the city dump, an old Raleigh road bike, was in such good shape, that instead of cutting it up, I hauled it down to the local bike repair depot to be tuned up for my wife. We've got the tent, and two extension ladders for antenna supports, about a dozen heavy-duty 12 volt marine lead-acid storage batteries in case the power-source poops out (Hee hee!), and enough other gear to choke a horse. Now all we need is to get organized by next weekend.

Barry: The best way to learn about eBay, is to go to their web site and download the New User info. It will tell you everything you need to know to get started. Fine tuning can be learned by observation. Also, be advised that all else being equal, eBay's prices on ham gear are 18% above average market value and WAY above hamfest prices. It is a nice place to SELL ham gear if you are looking for that, but if you are BUYING from eBay, you will very rarely find a bargain in equipment there. Components are a different matter, and I have had pretty good luck on tubes of certain types: i.e. 6CL6s, 12BY7s, 5763s, etc., at times. Good luck.

This unit appears to be constructed of black anodized aluminum with shield, 5 adjustment pots, a 12AX7 tube and a 1Z2 rectifier. It seems to be meant to screw down onto some other piece of gear (has two thumb screws in front and one in back and has wierd "keyway" knobs that probably mesh with some panel intended for the front). There is a single odd junction plug on the bottom of the unit through which all inputs lead. The unit bears the following identification on the front: Monitor F16-M-46251-1019 Does anyone know the origin or intended use of this unit? I worked through the circuit details by hand. Only one section of the triode is used and appears to serve as an amplifier for the vertical plates. The horizontal plates seem to have no means to apply a sweep unless this is somehow provided also by the hi voltage supply (one side is connected through a 20 M resistance to the filament/cathode of the rectifier). The adjustment pots seem to include the usual vert and horiz and focus and brightness plus a fifth which seems to be an attenuator for the input to the vert plates. Any info on this would be helpful.

That's one of the reasons many sellers specify a reserve bid (covers their expenses) .

When they quit crystal they went to an "ECO" or "Electron Coupled Oscillator." By happenstance they did not call it a "Lamb," or a "Dow," but these funnly looking oscillators became known as Tri-Tets when they used a crystal instead of a variable cap across the grid and cathode. It's a Triode oscillator with a Tetrode amp in the same tube. It was valuable because it could operate on a multiple of the crystal and just about any old crystal would work with the dose of current these things delivered Some authorities would tell the builder to put a panel lamp in series with the crystal and tune for minimum light, not maximum smoke. It all began with the Navy and a fellow named Lt. J.B. Dow who wrote in the Feb., 1926 QST. Jim Lamb of QST saw the circuit as a low Mu triode coupled by its grid to a high Mu screen-grid amp -- a Tri-Tet. Such circuits are out of favor now, but you can build one iwth an 807. Put a 400 Ohm, 2W resistor in the cathode and bypass it with a 0.01 cap to a grounded, parallel tuned circuit. Put a 7 mc FT-243 crystal across an RFC and from the grid to the top of the 400 Ohm resistor. If it is a 7 mc crystal, tune the cathode circuit to about 10 mc -- the rule of thumb in 1.5X the crystal frequency. In the plate circuit make another parallel tuned circuit at twice the frequency of the crystal. Key an 807 in the screen grid from the junction of a 5K 20W and a 10K 20W to ground. Feed the plate and the voltage divider with 350 VDC, put a parasitic supressoor in the plate lead close to the 807 cap, and bypass the screen with a .005 cap. Don' risk a favored HC-6. Stick to the rugged old FT-243 crystals even if you lower the voltage and use an ugly old 6V6. This material is from "The Variable Frequency Oscillator," Orr, W.

But I can't cleanly credit Lamb with the invention of the crystal triode-tetrode after having seen William P. Durkin, W2DHM, "Combined Oscillator and Doubler," for the Experimenter, QST, Dec 1932, p 40, which suggests the use of a 46 or 47 used as an osc, with an "80-m" tank keeping the screen (or "outer grid" in the 46) above RF ground, and a "40-m" tank tuning the plate. This is essentially the Tri-Tet with tank repositioned--about a half year before Lamb's publication of his version in James J. Lamb, "A More Stable Crystal Oscillator of High Harmonic Output," QST, June 1933, pages 30-32. [introduces the word tritet, no hyphen; later ARRL usage put the hyphen in]. In all, I find it hard to excuse Lamb's failure to footnote Durkin in June 1933. (BTW, the Durkin piece is notable for another reason: The rare usage of the 46 "dual grid" tube, which was intended for use only as a low-mu triode [plate and outer grid tied together] or high-mu triode [grids tied together.]) > Such circuits are out of favor now, but you can build one iwth an 807. > Put a 400 Ohm, 2W resistor in the cathode and bypass it with a 0.01 cap > to a grounded, parallel tuned circuit.

I dis-recommend using in the tri-tet hookup any tube with its suppressor grid or beam-forming plates internally connected to its cathode (as is so in most audio pentodes and beam tubes, including the 6F6, 6V6, and 6L6, and in many RF tubes, such as 807. The presence of the cathode-connected suppressor or beam plates adds direct capacitive coupling between the tube's plate and cathode, which in a tri-tet is above RF ground, and therefore compromises the isolation between the oscillator and amplifier portions of the tube; this can lead to increased crystal current and greater than necessary sensitivity of the oscillation frequency to the tuning of the plate. Even Lamb failed to note the effect of the beam-forming plates in his wonderful overview, James J. Lamb, "A Practical Survey of Pentode and Beam Tube Crystal Oscillators for Fundamental and Second Harmonic Output," QST, April 1937, pages 31-38, 106, 108. Another strike against the use of beam tubes as triode-tetrode oscillators (LC or crystal) is that the electron shielding of the screen by the grid (in a beam tube, they're aligned so the screen is in the electron shadow of the grid as far as the cathode is concerned) tends to make the screen less capable of drawing sufficient current in its job as oscillator anode. As it's put concerning the modified Pierce oscillator in the 11th edition of the Radio Handbook (p. 95), "A pentode tube with very high transconductance and a screen configuration which permits a fair amount of screen current will give optimum operation on harmonics. The screen acts as the anode of a triode oscillator . . . and some of the 'beam' tetrodes draw too little screen current to do the job." Video amp pentodes of the 6AC7, 6AG7, 6CL6, 6AH6, 12BY7 and similar class make fine tubes for any oscillator configuration in which the oscillator consists of the triode formed by the screen, grid and cathode, including the tri-tet. BTW, The first 6AG7 tri-tet I've seen in print is in Byron Goodman, W1JPE, and Hal Bubb, W1JTD, "A 56-Mc.

I have yet to hear the standard warning for Tri-Tets: The greatest crystal current generally occurs when you're trying for *fundamental* output from the crystal. Many published & commercially-made circuits include some means for shorting out the cathode tank when running the osc on the fundamantal. One common ham method was to bend over the corner of one plate of the condenser, so at "full mesh" it was shorted out (this is best done with condenser that limits rotation to 180 degrees, shorting happening right as you approach the full-mesh stop). Millen's 90800 exciter takes a less-kludgey approach, a simple toggle switch on the panel. Taking the cathode tank out turns the thing back into a straight tuned-plate tetrode osc. ...I see this done mostly where a beam-power tube is used, bringing us right back to the points made by Dave Newkirk and others about not using poorly-screened tubes such as the 6L6 for tri-tets--hams in the '30s didn't have 6AG7s (etc.) to use instead but we do. Hanging a pilot lamp in series with the xtal is cheap insurance for any power oscillator and well worth the extra 50 cents. A crystal no longer costs half a week's pay but they're not *that* cheap and most of the crystal houses are pretty slow! 73, --Bobbi KB9GKX "RJ" rbarmore@indy.net Roberta J.

For example, I bought a brand spanking new Tektronix 7A18A dual vertical amp plug-in unit with manual for $50. For some strange reason, some things go for reasonable prices (if not downright cheap) while others sell for astronomical prices that defy all logic. For example, I shopped around for a long time for some scope probes on E-Bay but could never touch the prices. I had a good idea of the open market value of what I wanted based on contacts with the Tektronix gurus (like Deane Kidd) and posted prices on the web. One item that I was following began to soar above that level so I alerted the high bidder of his cheaper direct purchase options via e-mail. He had already bid +50% by the time he read my e-mail!

It appeared in the ARRL "How to Become a Radio Amateur" handbook about that time. My cousin and I started in the ham game together and both built one. We thought we were real cool when we changed the tank coil to a B&W 80JEL (80 meter junior end link, remember?) plug-in tank coil instead of the lollipop stick wound job. Thinking back, the home brew coil with insulated wire was safer because this little rig uses a series tank, so the coil is hot with B+. We ran the poor little 6V6 to the gills. In the circuit, the screen is run at the same potential as the plate, which was about 350V. It really cooked. I soon got a crystal for 40 meters, but didn't bother with doubling - ran it straight thru. Sure enough, the crystals (I still have them) ran hot, but I don't remember ever blowing one. I remember straining to the static of my old (at THAT time) Hallicrafters Sky Buddy (my first "commercial" rig after my homebrew regen using a single 3S4, described in the same "How to Become" handbook) into the wee hours and working a station in NY State, on my end fed Zepp. Not bad from Houston! I was so excited I felt sick to my stomach! Almost threw up! When was the last time you felt that kind of thrill with radio? The little 6V6 was cooking along, the plates would start a cherry glow if you keyed down for a time. I had gone to water cooling via one of my socks dipped in water and pulled over the tube!! I don't remember ever blowing the tube either! We later plugged in a 6L6 and thought it was WAY cool! I recently had a fit of nostalgia (allowed, for us OF's) and wanted to recreate that old rig. I picked up an identical Sky Buddy at the Puyallup flea market here in Wa., and tracked down a copy of the ARRL HTBARA booklet describing the 6V6 rig and the regen. I want to recreate the little 3S4 regen, also, even if it is a cantankerous little booger. The soft music of the tube microphonics when bumped were magic! Hey gang, I had thought about offering a little kit of parts to get started building one of these little tri-tets. Maybe like the tube and socket, a nice variable cap (I have some new ones, about 150 pf, ceramic insul, teflon shaft, panel mount), maybe a pvc coil form (better than lollipop stick?), some fahnstock clips (think old timey), and some good mil-spec hookup wire to do the job, and a copy of the article from the book. The only other parts are one resistor, three fixed caps, and the crystal. After all the bad press on the tri-tet, though, I'm not sure there would be any interest. Or would there? I am going to throw one together breadboard style with a front panel - I like that old look. I'll see how it goes. How many others built that little 6V6 rig in the past to provide fond memories? 73, Jim W7HPK jimbowman@seanet.com Sandy W5TVW wrote: > Ah! The "tri-tet"!

The main reason why tuning a tri-tet's cathode tank too close to the crystal frequency is dangerous is that the triode oscillator section of the tube, as is true of any screen-grid-tube oscillator that uses the screen-grid-cathode triode as the oscillator, runs with essentially no output load. With this being the case, tuning a tri-tet's cathode tank too close to the crystal frequency results in excessive feedback, heating that, if carried to extreme, can fracture the crystal. Keeping this from happening is simple: *Don't make the cathode tank tunable.* If you're so inclined, you can spend considerable time at the bench fiddling with the LC ratio of the tank, and the frequency to which it's tuned, to optimize the oscillator's output on whatever frequency while minimizing crystal current. I'm not interested in such hairsplitting, so what I do is tune the tank to 5.9 MHz for 80-meter rocks and about 10.5 MHz for 40s. A fixed cap; a toroidal, powdered-rion-core inductor wound per the formula in the ARRL Handbook. No variable capacitor in the thing; it's sure-fire, and presents no more danger to the crystal than other circuits if used properly. (Keeping the screen voltage below the point at which yoopy keying occurs is another must. Back when these circuits were developed, keyed LC oscillators were the "rotten signals" to beat, and even a badly overloaded crystal sounded much more stable than an LC set. Nowadays, frequency stability can come before power output--it does in my station!) And no bent tank-tuning-cap plate or "short out the tank" switch, either. Why? Because, I find, the directive not to use the tri-tet for fundamental output is *misguided*. Using the tri-tet circuit, or some other configuration that uses the screen-grid-cathode triode of a screen-grid tube as the oscillator, does an important thing: It (largely) isolates the oscillator from the effect of load shifts at the tube plate. This is not only important for frequency stability. Using a standard "pentode" or "tetrode" oscillator (which Lamb aptly termed "tuned plate crystal grid") endangers the crystal in the sense that load shifts at the plate greatly vary the power fed back to the crystal. In the worst case sudden loss of plate load--such as the antenna connection failing in an instance where such an oscillator drives an antenna directly--makes the circuit's full feedback available to the crystal, at the crystal's peril. Circuits in which there is little or no feedback from the tube plate to the crystal, of which the tri-tet is one, are much more protective of the crystal in this sense. In practice, I've invariably found that, with a given tube (I've used the 59, the 6L6, the 12A7 [yes, *7*],) using the tri-tet configuration for fundamental output gives better keying (no yooping) and more freedom from frequency shift with plate tuning. Again, for 80 m crystals I shoot for a tri-tet tank resonance of 5.9 MHz; for 40-m crystals, 10.5 MHz. Because 40-m crystals are considerably thinner than 3.5-MHz ones, avoiding yoop with 40-m rocks usually means running the tube at a lower screen voltage than with 80-m rocks. (For best keying at 40 m, I use an 80-m rock and double. Hint: When doing this right into an antenna, don't use a pi-net at the output--it's a low-pass network that will barely attenuate the subharmonic at all!) Psst: Yes, the 12A7 suppressor is tied to its cathode. But it still made a nice QRP tri-tet. > Hanging a pilot lamp in series with the xtal is cheap insurance for any > power oscillator and well worth the extra 50 cents.

But keep in mind that the lamp is a variable resistance, and may therefore introduce chirp or yoop if it lights much. (Idea: I believe it should be possible to roughly determine the crystal current by comparing the brilliance of an RF-light lamp with lamp lit to equal brilliance with metered dc--perhaps with photocells or phototransistors would do it--but haven't gotten around to trying this yet.) 73, Dave Newkirk, W9VES dpnewkirk@home.com From glowbugs-owner@piobaire.mines.uidaho.edu Thu Jun 24 08:01:06 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id IAA06113 for ; Thu, 24 Jun 1999 08:01:06 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id HAA13550; Thu, 24 Jun 1999 07:53:32 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id EAA18289 for glowbugs-outgoing; Thu, 24 Jun 1999 04:40:13 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from mail.rdc1.nj.home.com (imail@ha1.rdc1.nj.home.com [24.3.128.66]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id EAA18284 for ; Thu, 24 Jun 1999 04:40:09 -0700 (PDT) Received: from cc328679-a.vron1.nj.home.com ([24.5.103.17]) by mail.rdc1.nj.home.com (InterMail v4.01.01.00 201-229-111) with SMTP id <19990624114002.TUXK1309.mail.rdc1.nj.home.com@cc328679-a.vron1.nj.home.com> for ; Thu, 24 Jun 1999 04:40:02 -0700 Reply-To: From: "David Newkirk" To: "Glowbugs List" Subject: GB> VFO Drive for Your Tri-Tet Date: Thu, 24 Jun 1999 07:40:03 -0400 Message-ID: <000001bebe36$4c938400$11670518@cc328679-a.vron1.nj.home.com> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 (Normal) X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook 8.5, Build 4.71.2377.0 Importance: Normal X-MimeOLE: Produced By Microsoft MimeOLE V4.72.3155.0 Sender: owner-glowbugs@piobaire.mines.uidaho.edu Precedence: bulk Status: RO Gang, In the 11th edition *Radio Handbook*'s "Simple Operating-Table V-F-O Unit" writeup (pp. 293-297) comes a useful "drive your crystal oscillator with a VFO" hint that some of us may not have considered: "The center conductor of the coaxial cable [from the VFO buffer output] may be coupled directly into the grid circuit of a 6L6, 6V6, 6AG7, or 7C6 tube. . . . A better arrangement affording a much improved impedance match from the coaxial cable to the first tube is to operate this tube as a grounded-grid amplifier. With this circuit arrangement the inner conductor of the coaxial cable is [ac coupled to the cathode of the first tube, with the first tube's usual cathode bias resistor to ground]. With this grounded-grid arrangement . . . no tendency toward oscillation will be experienced and improved output from the tube can be obtained either operating the stage as an amplifier or a frequency multiplier." I tried this in connecting a 12SJ7-12A6 VFO to a 6JC6-12HG7-6JB5 transmitter I'm developing and found such an embarrassment of drive that I can run the 12A6 screen at a quite low voltage and still get sufficient drive with the 12A6 plate far detuned. This hint is a particularly useful in retrofitting VFOs to oscillator tubes configured to run with the cathode above ground. Oscillator tubes without the suppressor or beam-forming plates internally tied to the cathode will give the best isolation. (Hint: This is why unaltered 6L6s, 807s, 1625s and other such tubes are poor choices for grounded-grid power amps: The grid can't act as a screen if it's bypassed by plate-to-beam-forming-plates capacitance.) 73, Dave Newkirk, W9VES dpnewkirk@home.com From glowbugs-owner@piobaire.mines.uidaho.edu Thu Jun 24 11:10:00 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id LAA06316 for ; Thu, 24 Jun 1999 11:09:59 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id LAA04655; Thu, 24 Jun 1999 11:02:23 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id HAA19832 for glowbugs-outgoing; Thu, 24 Jun 1999 07:44:54 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from postal.indy.net (postal.indy.net [199.3.65.16]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id HAA19827 for ; Thu, 24 Jun 1999 07:44:50 -0700 (PDT) Received: from indy1.indy.net (root@indy1.indy.net [199.3.65.5]) by postal.indy.net (8.9.2/8.9.2) with ESMTP id JAA25606; Thu, 24 Jun 1999 09:44:30 -0500 (EST) Received: from localhost (rbarmore@localhost [127.0.0.1]) by indy1.indy.net (8.8.7/8.8.7) with ESMTP id JAA17179; Thu, 24 Jun 1999 09:43:20 -0500 (EST) Date: Thu, 24 Jun 1999 09:43:17 -0500 (EST) From: "Roberta J.

Millen was not the only outfit to do so! In such cases, the user is better off running the osc as a TPXG if they're after fundamental output. New construction is another thing, and builders will do well to heed your ideas. The toroid coil/condenser for each band would fit neatly in an old tube base. Another version on the general theme is the Jones "regenerative oscillator," which uses an RFC in the cathode circuit bypassed by a few hundred pF. Haven't really analyzed it in depth but it looks to be doing similar phase-shifting tricks to the classic Tri-Tet. I built a single-6L6 version of this (on a breadboard, with an unfortunately high-pass output coupling scheme and other Crimes Against Something) and it works well on 40 and 80m, doubling or fundamental--mildly cooked a *very* tiny colorburst xtal with it once but larger ones and FT-243s survive happily, even with no load on the plate at all! A word to the wise, high-Q plate tanks and link coupling (or couple the tank to a pi-net as used to be done) are a *really* good idea for the Jones ckt; it's a good producer of harmonics. (Trust me--I used a low-C tank and bid fair to qualify for a "Worked All TV Sets" award). In re pilot lamps as current indicators, congratulations! You've re-invented Fred Sutter's "What, No Meters?" method *and* the grease-spot photometer. The latter item uses a pair of lamps, one fed with RF and the other from a variable voltage source with meters for current and voltage. The lamps are put in light-tight boxes with a common dividing wall, and a small hole (1/2" or so but I am working from memory) is drilled in an outside wall of the box assembly, centered on the divider and covered by a translucent substance. The original ham versions used a sheet of paper with a grease spot on it, hence the name. Anyhow, one applies RF power to the test bulb, then varies the voltage on the reference bulb until the brightness of each half of the grease spot is equal. Then you read the voltage and current and you've got power. Accuracy is said to be very good--human perception of "compared to what" is quite keen when the things compared are side-by-side. Fred Sutter's pilot-lamps-as-milliammeters notion isn't so precise, but he did publish (in "Hints and Kinks") a nice chart of perceived brilliance/color vs. percentage of rated current that will give the user reasonable "ballpark" numbers. An RF power-mesauring method akin to both of the above (and from the same time period) used a light-bulb test load and a photographer's light meter, working up a little calibration chart by running the lamp from line voltage through a variable autotransformer, measuring voltage & current as above. Disconnect the variac et al, apply RF and hey, presto, a terminating RF wattmeter. (A light-tight box is a good idea here, too, for obvious reasons). ...The "gotcha" with the RF power mesaurement schemes described above is, of course, that modern Mazda lamps have an ugly resistance vs. applied power variation, so load Z varies proportionately; if the only question is "power?" they'll answer it but if you want to know "power into a certain load Z," you're out of luck. (There are some tricks that can be played with combinations of tungsten- and carbon-filament lamps to flatten the delta-R/delta-P slope but carbon-filament lamps are scarce these days). Fred Sutter's meterless wallet-savers, however, don't suffer so much from the way light bulbs behave; since we don't really give a hang about the actual power (and the resistance of the lamp & delta thereof as current changes is negligable in most but not all cases--readers should have a look at Dave's very valid points about hangin' 'em in the xtl/grid circuit and why one should not choose for maximum glow there), they'll do a fine job. Not as precise as a fine old Weston 301 (might give a Readrite a run for the money!) but quite adequate for tune-up and answering the eternal question, "Am I gonna fry this tube?" :) ...A closing thought: Dave's new-old ideas* about light bulbs as measuring devices and the known limitations of light bulbs as loads makes me wonder if a clever person might be able to use a small lamp and a voltage-dividing pure resistive load to measure power. You'll still suffer from delta-R/delta-P effects but they could be minimized by swapping lamps to keep brightness in the upper range and using correction factors worked out from the known hot resistance of the lamps; load resistance of the device would stay reasonably constant, with the lamp's effect attenuated by the amount of voltage division used. Grease-spot photometry could still be used--throw a little Ohm's Law/Power Law math at the results and you're there! 73, --Bobbi ________________________________ * Lest someone consider that comment unduly critical, I'll say right here in print that it is a very fine conceptual leap; Fred Sutter was no slouch and a fellow who independantly comes up with the same notion starting from the same place (lamps as xtal-protecting fuses) is no slouch either!

I have what appear to be original 160 M coils, and they have a large air padder in the middle, but it cannot possibly be large enough. Thus far I have it working, but output is low. (I haven't checked the bypass and coupling capacitors yet.) Roberta's suggestion to make the cathode tank fixed-tuned is a good one; tuning the cathode tank does not have a gross effect on output, but it does on the crystal current! The lower you tune the higher the crystal current goes. By eyeball I think I am seeing about 100 Ma in the series lamp. This is OK for FT-243 types, but don't try the smaller ones! For a nearly correct schematic see QST, June 1937, pages 48-49, 80, Willard S. Wilson, "A 28 Mc Mobile Installation." The actual schematic also has some cathode bias, and only the screen voltage is variable. For a similar oscillator see Hints & Kinks, Volume 3, page 26, Dunning & Lindquist, "Composite Oscillator." 73 Richard Brunner, AA1P, rbrunner@gis.net From glowbugs-owner@piobaire.mines.uidaho.edu Thu Jun 24 20:26:41 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id UAA07350 for ; Thu, 24 Jun 1999 20:26:41 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id UAA09861; Thu, 24 Jun 1999 20:18:56 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id RAA24977 for glowbugs-outgoing; Thu, 24 Jun 1999 17:02:06 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from mail.rdc1.nj.home.com (imail@ha1.rdc1.nj.home.com [24.3.128.66]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id RAA24971 for ; Thu, 24 Jun 1999 17:01:53 -0700 (PDT) Received: from cc328679-a.vron1.nj.home.com ([24.5.103.17]) by mail.rdc1.nj.home.com (InterMail v4.01.01.00 201-229-111) with SMTP id <19990625000115.PZT1309.mail.rdc1.nj.home.com@cc328679-a.vron1.nj.home.com>; Thu, 24 Jun 1999 17:01:15 -0700 Reply-To: From: "David Newkirk" To: "Roberta J.

Lamb explains that topology, which had pretty much become standard by the 1960s, in his 1937 survey article. It's essentially a triode-tetrode circuit in which the oscillator is a grounded-plate Pierce. (I'm a fan of the "modified Pierce" myself, the essentials of which I've traced, in QST, to the mid-1930s.) > In re pilot lamps as current indicators, congratulations!

Being familiar with both ideas (and a great fan of Sutter, who I hope is smiling down at us as we converse) I don't rate as their re-inventor. :-D (The only place I'm sure I've seen a reference to grease-spot photometry is in my WWII RSGB Handbook.) What I'm after is the indication and measurement of crystal currents too small to appreciably light a bulb, and what I suspect is that a suitable lamp will be giving off detectable, invisible-to-the-eye IR at current levels well below that which results in a glow detectable to the eye. I'm hoping that an IR phototransistor might be a useful responder to such an emitter. > ...The "gotcha" with the RF power mesaurement schemes described above > is, of course, that modern Mazda lamps have an ugly resistance vs. applied > power variation, so load Z varies proportionately; if the only question is > "power?" they'll answer it but if you want to know "power into a certain > load Z," you're out of luck. (There are some tricks that can be played > with combinations of tungsten- and carbon-filament lamps to flatten the > delta-R/delta-P slope but carbon-filament lamps are scarce these days). How about this? I suspect that most of a lamp's resistance change with current occurs from cold to, say, 1/2 rated current. That being the case, how about feeding the load lamp with dc (or low-frequency ac) via a suitable RF choke, *and* (via a capacitor) RF? The dc would be a sort of bias--light the lamp to half its rated current to bring the R shift under more or less under control--and the RF would take the lamp the rest of the way to full brilliance. The control lamp would be fed only by low-frequency ac or dc, as before. We'd subtract the known load lamp bias power from the known control lamp power; the difference would be the RF power. And then we'd call CQ into the bulb to see who answers.

( i find the 1929 barrier to be a bit > arbitrary, though > i understand some demarcation must be in place ). The 1929 barrier isn't as arbitrary as it sounds. January 1, 1929, was when the new radio regulations adopted at the 1927 Washington Conference went into effect. On that date, hams suddenly had considerably narrower bands, in all: 40 meters changed from 7 to 8 MHz to 7 to 7.3 MHz; 20 meters went from 14 to 16 MHz to 14.0 to 14.4 MHz. Spectrum-gobbling signals that might have been tolerable in the older, wider bands had to go--so by order of the ARRL Board of Directors, Ross Hull undertook a Technical Development Program, the results of which appeared in QSTs of 1928, to develop better transmitter and receiver circuits capable of producing "1929 signals" and receiving those signals under "1929 conditions." Although I'd have to reread my old QSTs to confirm the details, I believe that part of the new regs also called for adequately filtered dc to be applied to the transmitter plates -- or at least the plates of the tube(s) supplying power to the antenna. So what AWA has done in setting the 1929 "barrier" is bias participants toward using hardware capable of producing a reasonably good transmitted signal today. Hull's work was pivotal in hams' continued enjoyment of their narrowed bands back then; his transmitter articles, in particular, were blueprints to success under the tougher regulations of "1929 amateur radio." 73, Dave Newkirk, W9VES dpnewkirk@home.com From glowbugs-owner@piobaire.mines.uidaho.edu Sat Jun 26 10:21:46 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id KAA09215 for ; Sat, 26 Jun 1999 10:21:45 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id KAA09678; Sat, 26 Jun 1999 10:13:31 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id FAA12236 for glowbugs-outgoing; Sat, 26 Jun 1999 05:54:49 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from m6.boston.juno.com (m6.boston.juno.com [205.231.101.197]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id FAA12230 for ; Sat, 26 Jun 1999 05:54:07 -0700 (PDT) From: mnhopkins@juno.com Received: (from mnhopkins@juno.com) by m6.boston.juno.com (queuemail) id ED2S6D8Y; Sat, 26 Jun 1999 08:53:04 EDT To: Boatanchors@theporch.com, Glowbugs@piobaire.mines.uidaho.edu Date: Sat, 26 Jun 1999 07:50:04 -0500 Subject: GB> FMLA: Talking Trash Message-ID: <19990626.075007.-181959.0.MNHopkins@juno.com> X-Mailer: Juno 2.0.11 X-Juno-Att: 0 MIME-Version: 1.0 Content-Type: text/plain Content-Transfer-Encoding: 7bit Sender: owner-glowbugs@piobaire.mines.uidaho.edu Precedence: bulk Status: RO All the QRPers don't drive SUVs and go backpacking on weekends. I learned that when I went down to Austin to a dinner for QRP Guru George Dobbs, G3RJV, and sat across from an OT. Frank, my pal who wants to take back 56-60mc with a Five Meter Liberation Army refused to go, saying QRPers were "transferring the receiving problem to the other guy." But I wanted to get him a memento and the OT needed part of a Command Set TX for something. I had one in the car and traded it for a little solid state TX. "Is that a snuff can?" Frank asked as he examined the offhanded style of the builder. I explained it was a cat food tin standing in as the chassis for a "Tuna Tin Two." An entire series of Doug DeMaw revivals from the '70s is underway, I told him, and mentioned the Herring Aid Five RX and the CB (chipped beef can) Slider VFO. I was able to trade for this piece only because the builder succumbed to the widespread QRP obsession for circuit board clone projects -- the fellow tossed his homebrew for a ".38 ACP," or some such will-of-the-whisp West Coast board kit. Frank sneered at that, but he was engaged by the "ugly" style of building evidenced on the Tuna Tin TX. I soon forgot about the trinket, but not Frank. Three days later I happened down to the basement to find Frank resplendent in rubbish. He explained his new VFO would never settle down on a solid tin base so he ended up putting a 12A6 Tri- Tet on the metal end of a paper Magnesium Citrate carton he termed his "Epsom Salts ECO." Then he saluted Native Americans with the visage of a warrior on the base of his interstage "Calumet Coupler" which used a baking powder can to hold a 6AQ5 set up as a buffer. Next came a mildly pear shaped platform with tapped coils and a dual variable. He called it a "Deviled Ham Doubler," and he must have rushed it into service as Charlie, the demonic white ferret, was clawing at its lower edge despite the considerable potential danger from the microwave oven chassis Frank was using to power all this stuff. The output was single ended, which is strange for Frank, but he said he was working out the kinks on 10M before he took it up to 5. His receiver, termed a String Bean Super-Gainer, used 303 cans for shields over the coils he wound on paper product tubes and someone's old cabinet door supplied the base. Frank always prefers to build on wood, and it is a good thing since he won't use a transformer unless he needs big voltage. He rigged two mayonnaise jar tops on threaded shafts for a neutralizing cap. He had a Hellmann's and a Kraft and said he was careful to put the Kraft on the low side because, he felt, Hellmann's caps took HV better. I just ignored that. These old timers have all kinds of superstitions. He fired up the rig and dipped the 813, which he mounted on a big can that once contained "Polish" sausage, altho that is not what it said. Frank won't say "German." It is something left over from the war, I guess, but when he sees a Rin-Tin-Tin looking dog he calls it an "Alsatian." In short order he was working some of his pals at a CW clip I cannot follow, but on tune up the final plate cap, cut from tuna cans, arched over. The ferret took off and Frank said, "must have been some dolphin in that one." I could not see if he was joking and was afraid to ask. The whole set up was impressive, like some adult's electric train, and it took up about as much space, but Frank is not into miniaturization. It covered our 6-foot bench and at the end he stacked up some milk cartons to hold the final, which was partially obscured by a grocery sack to keep the ferret out of the high tension leads. "What kind of output are you using on your Polish Sausage PA ?" I asked. (I decided to go along with the WWII convention.) "Link, of course," he said. I still could not see his face. de ab5L, michael in dallas, MNHopkins@JUNO.com Student of Tecraft, ICM and Six Meters' Golden age: 1957-58 Box 226841, Dallas, TX 75222 Copyright FMLA XLII From glowbugs-owner@piobaire.mines.uidaho.edu Sat Jun 26 11:00:33 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id LAA09244 for ; Sat, 26 Jun 1999 11:00:33 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id KAA11309; Sat, 26 Jun 1999 10:52:20 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id GAA12474 for glowbugs-outgoing; Sat, 26 Jun 1999 06:51:34 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from m6.boston.juno.com (m6.boston.juno.com [205.231.101.197]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id GAA12468 for ; Sat, 26 Jun 1999 06:51:10 -0700 (PDT) From: mnhopkins@juno.com Received: (from mnhopkins@juno.com) by m6.boston.juno.com (queuemail) id ED2WF27C; Sat, 26 Jun 1999 09:50:46 EDT To: Glowbugs@piobaire.mines.uidaho.edu Date: Sat, 26 Jun 1999 08:47:27 -0500 Subject: GB> AWA and the 1929 rule, TTT?

I scored one off the Ebay, which arrived yesterday. Seems like it would make a good IF and foundation receiver for use with VHF UHF converters to reach the higher bands, like 2300, etc., with a lighthouse tube based converter. Would also work as an IF for 2 & 6 meter work. I'd like to use it without tearing it up, since it is so nicely designed and built. Also need information on the JAN6AJ5 and JAN28D7 tubes, which it uses. I found a diagram for the 6AJ5, which seems to be a pentode, but that's all the info that I have. The JAN 28D7 (if it is similar to the 7D7, appears to be an triode/pentode, with the grid of the triode connected to a grid in the pentode. The receiver has a long strip of what looks like audio transformers - some of which may be audio filters, used to separate out the three signals commonly used to control three lamps on the pilots instrument panel - the outer marker lamp, the middle marker lamp and the inner marker lamp. This seems to agree with the seven of pins in the front panel connector, which should include: ground, +28 Volts, DC, some form of B+ (based on the voltage ratings of the capacitors, inside), a remote audio output lead and the three lamp driver leads. I am building an adequate power supply for it (as well as for use with some ARC-5 receivers) and can probably reverse engineering it sufficiently to get it working. But, it would be nice to have the military maintenance manual for reference, since often there are sublties that one might overlook. I would appreciate any data that anyone might have leading to the acquisition of such a manual.

I guess radiomen can be classified according to whether they desire to hear only pure DC T-9 signals, or whether they search out and work those rough AC, somewhat modulated, rowdy-sounding, multitoned signals. I fall in the latter category! Hearing a "rough" signal on the ham bands immedi- ately takes me back to those joyous evenings sitting the Central Pacific USCG 500 kc watch "looking after" dozens and dozens of ships plying the shipping routes in all directions of the compass. Some slop-buckets must have been running AC on their plates, others (like myself at NMO) pur- posely kept our transmitters in A2 (with a tone modulating our CW signal) which gave our signals an orchestra-like sound, complete with dozens of AF harmonics filling the guard band (495-505). Listening to the cacophony of discordant tones, growls, buzzsaws, banshees, foghorns, bells, buzzers, and whistles on 600m made me feel like the luckiest radioman in the world, and to think I was getting *paid* to hear this beautiful-sounding symphony every night made it even sweeter! (Some signals had tones which varied in freq'y with the roll of the ship.) BTW, I have a home-made "chopper": It's a motor-driven toothed wheel in series with my hand-key, providing a make-break circuit - probably provides a square-wave of a couple hundred CPS super-imposed on my signal. Now, I've never used it on the air (but have into a dummy load), but I smile at the thought that I do have ICW capability, just in case... Post script: By design, 500 kc Auto Alarm receivers *only* responded to A2 tone-modulated signals; part of the ITU-dictated distress procedure was to send the distress message send in A2.

When, I was a kid and working rare DX, the rarer the DX the stranger the signal. It was easy to pull them out of the QRM because they sounded unique, something signals seem to lack, today. And, I would wonder what the guy's rig looked like. Was it built on a board? Did it look like the wall full of panels and meters as many of DX stations, pictured in the ham magazines of the day, looked like? In those days, one had to have a terrible signal before anyone complained. Nobody ever told me my crystal controlled rig drifted objectionably until about a year ago, or was it two. Chirp? Just about everybody had a little chirp. But, today, chirp is not to be tolerated. I even had a guy break into a QSO, just to tell me that I had a little chirp. I've been told that anything less than a pure DC smooth signal does not belong on the air and is not good practice - as if I never knew that. But, it's true, though, what can I say? The Future is always kinda strange in that it brings things of beauty and then sweeps them away. They linger like the fragrance of a flower as if only for those who can sense them. And, then they are gone. Maybe it's enough to have heard a "cacophony of discordant tones," on a late night watch, in a world which lives in caos yet worships order. The game has changed. Maybe, all the guys (like me) that miss signals with a little character should exodus to 160 Meters, where there are few purists to bother. We could hold a "Chirp and Buzz In," and nobody else would know anything about it.....

I fall > in the latter category! I'm there, too, with the qualification that those signals are okay during special 'tests, but less okay at other times. (A bit of yoop or chirp is okay with me anytime, but I confess that I work hard to keep *my* signal from sounding that way! :-D) And to put it into perspective, in the late 1980s and into the early 1990s, when I was working at ARRL, every Friday I had the privilege of sitting in on a special lunch in the office of QST Managing Editor Laird Campbell, W1CUT, attended by a number of key retired ARRL staffers. (On a typical day, it'd be Laird; John Huntoon, W1RW; By Goodman, W1DX; Joe Moskey, W1JMY; George Hart, W1NJM; me, and several others; with luck, Perry Williams, W1UED, would sit in, as would Dick Baldwin, W1RU, if he was in town for an IARU function. One Friday in 1989 I had the privilege of reintroducing my dad to the group; he'd worked with them in the 1950s when ARRL was based in West Hartford.) Talk about a group with a handle on history! One Friday I brought in a cassette tape of a bandscan during a just-concluded AWA Old Time Transmitter party in which Goodman and I had participated. Everyone leaned in and listened, almost holding their breaths. Finally, listening to a particularly wonderfully chirpy VE3, Huntoon leaned back in his chair, shook his head and said, "That's just beautiful--*beautiful*!" It brings tears to my eyes." I think Jeff conveyed the romance well. Those of us who haven't lived through the times when daily use of radio routinely involved such signals can only approach an understanding of how evocative their sounds can be. At base, what's going on has to do with what Alastair Cooke, who I never miss in his "Letter from America" talk each week, said at the beginning of a particular Letter: What we mean when we say "Back in the good old days" is really "When I was young." In this case of radio old-timers, it means "When radio and I were young." This is as good a time as any for me to announce that I hope to meet more of you on the air sooner rather than later now that we just closed on a house here in Montclair. There are plenty of tall, 70+-year-old trees on the property, and I'll be getting some wires up in time for considerable fun in the fall and winter. 160, 80, 40, and 30 will be my mainstays, although I find myself greatly attracted to 80 (especially 3650 to 3725) these days. I'll be getting back to work on my special SKN rig, for which I expect to work up keying circuitry capable of giving my signal a lovely bong--*that's* the signal sound that gets *me* misty, and I've been licensed "only" since 1969! 73, Dave Newkirk, W9VES dpnewkirk@home.com From glowbugs-owner@piobaire.mines.uidaho.edu Sun Jun 27 01:05:53 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id BAA09895 for ; Sun, 27 Jun 1999 01:05:52 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id AAA14861; Sun, 27 Jun 1999 00:57:29 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id UAA18662 for glowbugs-outgoing; Sat, 26 Jun 1999 20:56:42 -0700 (PDT) Received: from localhost (keng@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with SMTP id UAA18654 for ; Sat, 26 Jun 1999 20:56:14 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: keng owned process doing -bs Date: Sat, 26 Jun 1999 20:56:04 -0700 (PDT) From: Ken Gordon X-Sender: keng@piobaire.mines.uidaho.edu To: glowbugs@piobaire.mines.uidaho.edu Subject: GB> FD-99...

Now, I have never minded a bit of chirp or yoop, and not so very long ago worked a fellow who had put an ol HB xmtr back on the air that drifteted 10kc or more during a transmission [1]; my rule's always been that if it was clear enough to copy, the sigs were okay (though really funky ones deserved to be told). There's an AF-67 on the BA air with *amazing* chirp...and it's armchair copy, so who minds other than a little kidding? But the recent thread reminds me of the SS British kit I built a couple of years ago. I was running it with a power supply I *knew* was inadequate; just wanted to see if the smaller-than-a-postcard xcvr [2] really did work. First station I worked kept tellin' me over and over that it chirped; I acknowledged and explained why, but the poor fellow just couldn't hardly stand it. (Maybe he thought an OO would go after *him?*[3]) Seemed a bit odd at the time; now I'm starting to understand--he'd probably never even *heard* a less-than-perfect note! All the more reson to get on the air with old gear and let the folks hear 'em. Nothing too egregious--raw AC is right out and most modern xcvrs aren't so good for following major drift unless the op's got a good handle on split operation--but sheesh, a little "character" just makes the sigs easier to pick out of the clutter! (As does hand-sent Morse, or maybe I'm just getting old--some of those "perfect" keyers are as rough to swot as a 15-wpm bug with 40-wpm dits, especially when handled by a nit who doesn't understand word spacing otta be longer than character spacing!) ...Would love to work a little 160; sadly, around here, there's *heaps* of crud down there, so I need to look into the various noise-cancelling schemes before making any serious efforts. 73, --Bobbi _____________________________ 1. I've always tended to set the receiver where it can be tuned left-handed. Just from habit--*that* QSO explained why the OTs recommended the practice! Good ol' Drake receiver, it was easy to track right along after the drift. 2. A Walford Electronics "Wedmore," very fine with a good supply; if a person's going to mess with sand, it's worth finding out what Tim Walford's got available--very nice stuff, from QSL-sized rigs worthy of Fred Sutter through some nicely sophisticated gear and none of it very expensive. Easy to build but not paint-by-numbers; he assumes the builder's got a clue. 3. Have we done *too* good a job of making newcomers fear rotten sigs? Poor guy seemed to fear he'd get a late-night knock on the dorr from FCC, FBI and CIA for working a chirpy station! KB9GKX "RJ" rbarmore@indy.net Roberta J.

I listened on a Yaesu general coverage RX I later sold for $300. It sounded OK so I began to click them off one afternoon. But the third guy I worked was obsessive about my signal -- especially after I recited the TX. I listened again -- no change. I was keying only the PA. Turns out his compliant was that the THIRD little red number right of his digital readout was not steady. Another Obsessive-Compulsive ham, of course, but the experience set me thinking , again, of one of the great paradoxes of radio. One would suppose the signals would become less stable as one went up in the spectrum. But in fact, I hardly ever hear a really bad 6M CW sig and the home of chirp and such is 80M, where dwell also the lids with the cursed Vibroplexes that send dits at 80 WPM and dahs at 18.

The U.S. Air Force acted as the regulating body for all (military) communications in Japan as the FCC had no jurisdiction in a foreign country. They also regulated use of amateur radio frequencies & power levels by US forces operating from the military bases. One of the restrictions imposed at that time was that hams operating from US military bases could not communicate with local Japanese nationals. Imagine calling CQ and not being able to reply to the amateurs calling in your own backyard! Curiously, there was no restriction made on contacts with hams in the Soviet Union. So when propagation was poor I ended up working bushel baskets full of UA0 stations on 40M CW. The time period was 1970 and the years following, i.e. part of the Cold War era. For a newly licensed ham this was great fun and a real eye-opener. Those UA0 stations had some really awful sounding signals!, but there was no mistaking them even as they drifted and chirped across the salt-water path from Russia to Japan. Actually I found it easy to copy them despite their somewhat raspy and drifty signals. Power supply regulation was an obvious problem for many of them, but it didn't stop them from plying the ether. It didn't discourage me from working them either!

Ohboy, airplane stuff! The frequencies of the resonators in this receiver can be found from this bit, found at http://www.rvs.uni-bielefeld.de/~ladkin/Reports/navigation.html#ILS ---------------------- ILS marker beacons have a rated power output of 3 watts or less and an antenna array designed to produce an elliptical pattern with dimensions, at 1,000 feet above the antenna, of approximately 2,400 feet in width and 4,200 feet in length. Ordinarily, there are two marker beacons associated with an ILS, the OM and MM. Locations with a Category II and III ILS also have an Inner Marker (IM). When an aircraft passes over a marker, the pilot will receive the following indications: OM - blue lamp, 400 Hz tone MM - amber lamp, 1300 Hz tone IM (also labeled FM/Z, BC or airways) - white lamp, 3000 Hz tone The outer marker (OM) normally indicates a position at which an aircraft at the appropriate altitude on the localizer course will intercept the ILS glide path. The middle marker (MM) indicates a position approximately 3,500 feet from the landing threshold. This is also the position where an aircraft on the glide path will be at an altitude of approximately 200 feet above the elevation of the touchdown zone. The inner marker (IM) wll indicate a point at which an aircraft is at a designated decision height (DH) on the glide path between the MM and landing threshold. ------------------------- Some of the uses of markers went away with the demise of the old radio range systems, such marking the 'cone of silence'. I know of no fan markers (FM) currently active in this area (north Alabama). A description of some of the obsolete uses can be found in Terman's Radion Engineers' Handbook (1943), pp 897. -- Dan Kerl dlkerl@ro.com From glowbugs-owner@piobaire.mines.uidaho.edu Mon Jun 28 11:53:51 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id LAA11535 for ; Mon, 28 Jun 1999 11:53:51 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id LAA20614; Mon, 28 Jun 1999 11:45:02 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id IAA09158 for glowbugs-outgoing; Mon, 28 Jun 1999 08:33:41 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from weedcon1.cropsci.ncsu.edu (weedcon1.cropsci.ncsu.edu [152.1.207.51]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id IAA09153 for ; Mon, 28 Jun 1999 08:33:38 -0700 (PDT) Received: (from na4g@localhost) by weedcon1.cropsci.ncsu.edu (8.8.8/8.8.8) id LAA12550; Mon, 28 Jun 1999 11:31:59 -0400 (EDT) (envelope-from na4g) From: User Na4g Boatanchor Bob Message-Id: <199906281531.LAA12550@weedcon1.cropsci.ncsu.edu> Subject: Re: GB> Light bulb DX (What about Buzzer DX???)

I might suggest also, that due to power supply filtering constraints of the early 20's, running AC power was musical, at best, with things like slop jar rectifiers and 1ufd filter caps. But, even the early sets can put out very respectable signals with battery power and reasonable coupling. For example, the earliest reference to a ``Hartley'' sending set that I can find, touted as the worlds simplest sending set, dates from about 1921 in Gernsback's Radio News, in one of the newcomers columns. I have built many sets using that exact design, running on batteries, and loosely coupled, and they work rather well for 1w or less output. Almost any tube that you have can be dropped in, and still work. Only two things are well to keep in mind about the early sets. 1) never direct couple them. 2) never overload them. Other than that, if it will run stably on battery power, without an antenna, or with just a small dummy load, it will usually do fine hooked up to the antenna. > The dual triode won't appear 'till 1934.

There were some combined tubes back in the early 20's, but they were very expensive, and mostly experimental. The name of Scott (Brit?) seems to be associated with that, and there was a Brit or German firm that made BC sets with such combined tubes, because taxes were less on them with only one valve in the set as opposed to several. Any Brits on the list that can confirm that? > I have some 19s but could not afford to buy more at the present asked > price. But if I could use a 6SN7 I could field a two valve station or, > by copying C.F. Rockey and others, even a one-tube station. Folks, there is Nothing, repeat Nothing wrong with subbing a later tube in an early circuit, and still calling the thing an early repro set. If you are not running the AWA thing, where the real tube counts, then put anything there that will work and allow you the fun of GB'ing the beastie. I swear by the 6SN7ish sort of thing, because they are still relatively common for play tubes and they can be wired up double to make one triode with a little adapter to fit an '01A socket (plus the right voltages), or run separately as independent triodes. > Perhaps we need a Tandem Triode 'Test for those more interested in > circuitry than historic accuracy. That is the joy of a triode.... singly or doubly or triply they are still a triode. Remember, one of our early GB folks (now sadly not on the list) ran 833's in his regennie detector. A triode is a triode is a triode..... (well that one was a little hotter than the rest.....) Pick a design from an article, and use that as the period.

Hartleys love it down on those ``short useless waves''. I was running the 40M vertical loaded up on 160. It works, fair, but it works. Anything from 45 feet of end fed whatever, worked against any kind of 45 foot or longer counterpoise wiiiiilllll load up on 160. Even a 15 foot fishpole whip loads on 160, but won't do transcons, very well. You will have to have a series antenna tuner of maybe 300pf-500pf cap and a coil of roughly 4 inches diameter, and 50 turns of no. 14 copper household wire. Tune for max out with a FS meter and run with it! My favorite antenna for 160, still, is an end fed roll of 100 feet of storeboughten wire with a similar counterpoise laid out on the ground. I can work everything out to 1000-1500 miles, easily, in winter and out to 300 miles or so in summer with only 25 watts or so. Cranking up Big Bertha Radiomarine to 250 watts, gets me transcons in winter on 160. There is a fellow, Gene, up in VA, that is on 160 CW yearround.

My guess would be anything from about 1955-1965 should have one design for a 50-75 watt or 90 watt set using maybe a 6AG7/6CL6 oscillator and the 6146 buffer. Before that time (1946-1954) I would expect a 6L6/6AG7 oscillator and an 807 final as typical. There was even a mid 60's single 6146 set that had about 35 watts output using the 6146 as the xtal oscillator (1964?). I dunno how well they worked, but the Johnson Viking Adventurer, or the Globe Scout or Heath DX-60 circuits would have been very typical of what to expect. If you can find one of those schematics, it should serve as a good starter, or find one of those handbooks. My novice Adventurer was always marginal. The Globe Scout was fair. But the DX-60 always was rock solid. I would say that to copy it would be a fairly good strategy. (Dave Newkirk, are there any particular HBK years you can recommend from your experiences?) (Jeff, send me your snailmail and I will copy you off a couple of schematics.)

Good Point, Bob.... I was thinking receiver and transmitter would be of the same period, in the above, but it would be good to break it out to where the regennie folks or such had a receiver advantage. Maybe something like: (Pre-1930[4]/1930-1942[3]/WWII[2]/Postwar[1]) TX power (5W[3]/50W[2]/500W[1]) mode (CW[3]/AM[2]/SSB[1]) type (HB[2]/commercial-military[1]) (Pre-1930[4]/1930-1942[3]/WWII[2]/Postwar[1]) RX type (HB[2]/commercial-military[1]) For equalizing distance effects, 0-1000 miles = 1 1000-2000 miles = 2 >2000 miles = 3 Points for a qso would be: TX(vintage x power x mode x type) x RX(vintage x type) x DISTANCE. All of this is based upon info you are going to want to minimally log, anyway. Most of us would make maybe 50 QSO's so that would entail a little calculating, but might not be too unduly reasonable. Folks with peanut whistles would get the advantage over big guns. Maybe adjust points to favor the lesser stations, even more? Would something like that make more sense? As a prize, the top 5 points stations get a certificate to throw darts at?

I tried a few of these kinds of things in the early 50's, but surely did not know what the hades I was doing then..... I have always wondered about setting up a spark set with some proper coupling and proper tuning (the real spark sets were not well tuned but had only one ``tank'' circuit). I would think that a 3 stage tuned circuit of tanks, link coupled at critical coupling or less would sharpen up the historically poo-pooed spark wave, until it actually would meet modern requirements as to harmonics and out of band operation, etc. It would still be as wide as a broad AM wave, modulated with 100% modulation and a complex audio wave form. It might be fun to try that with a buzzer setup, and run it into a spectrum analyzer and actually do the response curves for frequency and harmonics. The type of spark discharger (plain gap, rotary gap, quenched gap) also has an effect on the purity of wave and sharpness of wave. If you actually look at the frequency response of a real spark set (see Elmer Bucher, again, for a plot of the actual wave of a marine spark set), the wave is not as ``broad'' as misconceptions lead us to believe. Also, with reduced coupling, it could be improved. Although the spark set would never match up to a good tube set for purity of wave, it might still be an interesting pre-GB thing to play with, for fun, assuming it could be tamed a little. It is one of those interesting oddities from way back in time.....

Interesting, that would be an untuned plain gap circuit, and the most prone to harmonics, etc. Now, what if that were well shielded and filtered on the power supply leads, DC was used as the power source, the ``gap'' was adjusted carefully to give a good note, and several tuning tanks were used to keep the wave sharp? Hmmmmm..... Neato..... I tried it once with an auto vibrator, 12V, if memory is correct, pulled from a car radio. Mine also had no tuned circuit, and I could hear it in the sw rx about 500 feet away, with several feet of wire antenna as the radiator. With no antenna attached, it could only be picked up around 100 feet away. That was when I was a GI, and the folks in the barracks thought I had totally gone goonie lugging a car battery and funky board all over the grounds. I proved to myself that it did work...... sort of.....(:+\\..... I did not know Morse then, so I couldn't try sending anything but an odd pattern of dits by connecting the battery on/off. There is a friend in town with a couple of real spark sets. One a plain gap ham set from the early 20's, one a rotary gap set from some school that used to teach radio up in Philly, and the third I don't remember offhand what it is. It is fun to take them to local ham classes and set out the regens and key a few dits..... sans antennae, of course. They can be real hash, ahh, err, signal generators, untuned. But, that still begs the question of whether or not a buzzer set could be cleaned up enough to try some QRPP part something-or-other demos or experiments. Any one else got any odd spark set experiments to report? This is getting interesting.....

I was in a bit of a hurry when I wrote that. Maybe I should explain what I meant before everyone thinks wrong thoughts about me. I am all for rigs sounding like they should. If a rig is expected to chirp, let it chirp and let others enjoy it. RAC and A2 sounds great to me too. What I am objecting to are rigs that are set up to exaggerate the chirp or note. I have heard a few Hartleys on the air that sounded perfect and I know that with even the smallest amount of care one can be made that only chirps maybe three or four hundred cycles or so. What I am objecting to are some rigs I heard that were chirping four or five kc/s with clicks going out past that or A2 that sounded like a bad AM rig modulated with a kazoo with a wet reed. Stuff like that isn't making any friends, especially with other ops that are trying to operate close by. I think one of the 'missions' of the GB list is to educate other hams in the way of the firebottle. One excellent way of doing this is by working them with old-style gear. If they hear a clean, stable (within the limits of the technology, of course) signal then they will be impressed and hopefully be inspired to make their own firebottle rig. If what they hear is a mess then they will not want to waste time and money on something that they would be embarrassed to sign their call with. I am sure a lot of really foul signals were put on the air back in the old days. Parts were scarce and expensive and I am sure the desire to get on the air forced many into making do with what they had. I bet the guy running RAC would have been glad to use a filter if he had one and I bet he made one as soon as he could. If there was one thing I wish I could transplant from the ham radio era our grandparents knew to the ham radio of today it would be the ham's spirit of continual improvisation and improvement. The ham of the 20's and 30's strove for the best signal possible and I think we do them a disservice if we represent their efforts with anything less. I enjoy a nice clean A2 signal and a bit of RAC is good too from time to time just to show the newbies what it sounds like if nothing else. Go wherever your heart leads and do it well. Build it, get it on the air and tell us about it. 73 and ZUT!

He said that over the headsets it sounded like a beautiful violin. The tone or pitch was determined by the pull of the magnetic field on the arc. Has anybody ever come across one of these things?

A friend of mine, who is also AWA, calls it ``scary'' rather than disgraceful. He is now known to old hands by his ``scary'' note, after a report from a fellow down Atlanty way. Also, ol' Bruce Kelly, now hobknobbin' with Fred Sutter, about the virtues of Miss ``Tuffy'' 6L6, regularly had one of the finest sounding primary keying sets you have ever heard (that set is sorely missed these days with that slow and steady fist). It's note rang like a fine crystal bell, of goodly note. Both of these AWA folks, could/can/do/did run with the best on their sets. It be kindof ``interesting'' to compare notes, then go back and fiddle some more with Grandma Hartley. They know/knew how to get the period signal, and they were old enough to have lived in those days. Sadly, many of them are now going SK, and we will miss those ``interesting'' sigs, down the road aways. >I am all for rigs sounding like they should.

Folks, Conard has it exactly right..... a period set should sound like its period. Hartleys can be as good as most late model sets, so period sets can be pretty fine with a little care and TLC on the things. Most folks don't realize just how fine the period sets can really be. A good period Hartley can run with the big dawgs, just like a Ten-Tec. Yer Hartley ain't had a good wringin' out till it be hustled along QSK at 35wpm or better. If it can handle that, well, it be well adjusted. If it can't, it still needs some fiddlin'. Once properly fiddled, then it be pure musick, sans bloops, whoops, klicks, swishes, an' buzzes. I would agree that there were some AWA sets that were more than scary. Any set that traverses more than 5khz up and down at one keydown is probably overloaded/overcoupled, and could use some revising. I have noted that not everyone on the AWA fracas seems to have all the bits together, as one might expect. Mebbie that is the AWA crewe in training..... We, Glowbuggites, of course, being better of the training and technical artes, can do better, right? Rah, Rah, Rah! Actually, we share a lot in common with the AWA folks, in history, traditions, knowledge, and fun. We just get on the air, all the time, with our olden sending sets! >I think one of the 'missions' of the GB list is to educate other >hams in the way of the firebottle.

Yes, we must carefully educate others in ``the way of the firebottle''. Mebbie paraphrase that to ``the way of the glowbottle''. That includes not only the QSO's but also hands-on GB'ing and getting them to mix up their own sending sets. I sense many do not have a yardstick of comparison as to what is expected out of good ancient sets, vs really rotten QRM, as T.O.M. was wont to say. That also, should be part of our mission, i.e., to help all hands understand what a real period set can do, and what it sounds like when purring along like a kitten, rather than a feisty, touchy ol' alleykat. >I am sure a lot of really foul signals were put on the air back in >the old days.

But, usually, with some knowledge and fiddlin' many of the old parts can be made to work well, still, and we will make/sub as necessary to get the beastie going, with as good a note as reasonable, for the period. Too bad about the ACW/ICW/A2 bit... I like the sound of that, too, and, it can be read on a tuner with a xtal detector! IF AM is allowed, still, why not A2.... just thinking out loud.....(:+}}... We are a scant bit off from that scarce parts bit of old, in that it is like we are on the far other side, where getting parts of old is a problem. But, even with hand made parts, we can and should try to put out the best signal that our period set can rightly be said and shown to do. They can usually do much better than most folks think. For sure, let us all do it and report it, and also MAKE it work, and work WELL. Even old early 20's sets can be made to sound like yer sandysolidstate thing, with a touch of care, and the right knowledge. It behooves us GB folks to share that ``right'' knowledge, so all can learn and enjoy..... Then we can one-up even them thar AWA folks (although they can run some right fine '29 style MOPA sets that are easily comparable to a Ten-Tec....., but we GB folks can put up easily as good a run on Hartleys.....(:+}}.....). We GB folks can do and will do to make it work and work well, right?

If you follow the things that you are interested in, on the Ebay Auction, for a while, you'll get a feel for what the prices on things generally are. Track the things that you are interested in, but, don't bid on them until minutes before the auction on the particular item is about ready to close. By then, the competition has "shaken out" and the price is closely established, although one can be surprised, occasionally. If the price is already above what you are willing to pay, don't bid. Some manuals go for practically nothing. But, there is another factor. Things keep coming along - the same kind of item continues to show up as often as two or three being offered for sale, within a few days. It's like things show up in jags, with folks bidding the most on the first to show up and then as more of the item continue to show uip, the price declines. That is usually a good time to bid on something. More often then not, it seems like, the items that I am interested apparently do not appeal to a wide following of people. As a result it is possible to separate the bidders into different groups, which narrows the field of folks who will bid on any one thing. So, far, I have isolated the following groups: 1. The Audiophiles - bid on a narrow selection of parts, mostly tubes like 211's, 300's and other hyped audio tubes, which have had intense media exposre in audio. 2. The what I call "Heritage ham builders," who go after tubes like 45's UV-201's, those tubes which have had the most media exposre in early wireless circles. 3. The none builder, boat anchor user/collector - likes to buy high end stuff like Collins, National, etc. wants pristine stuff in working order - only....no scratches, no dents, no modifications, all the right knobs, must be guaranteed to work. 4. The collector - usually also a dealer- buys to fill holes in his collection but pays for what is in his collection by dealing in the same line of stuff. Will buy a whole box of tubes in order to score the one he wants and then will sell the rest, usually for more than he paid for them. Knows that a tube sold by itself or in pairs will bring a great deal more than sold as one tube in a large box of tubes (as an example) and knows what folks are paying for tubes, because he tracks tubes and tube prices. What is said here, applies to any item that has collectable value. 5. The restorer/collector - likes to tackle projects which have a high degree of potential successful restoration. Likes to buy shabby looking, but complete and usually workable equipment to basically cleanup, touch up and to make simple repairs to. May buy things which "light up," but don't work, but are otherwise clean and complete. 6. The solid state user - likes to buy later models of useable solid state gear and is willing to pay higher prices to get it. Equipment must be in working order and in good shape. 7. The boat anchor user. Equipment must be in working order and in good shape and will pay high prices to acquire good equipment. 8. The homebrew builder/rebuilder - buys parts and hulks of gear. May buy several to get enough parts to build one that works and looks good. Also, buys parts and tubes for use in home brew projects. Usually seeks the most popular tubes, like 6146's, 807's, 6AG7's and 45's. 9. The military collector/user - prefers to buy pristine old military gear, as opposed to 'butchered' military surplus. 10. The explorer/experimenter - usually doesn't have a lot of money to spend, but will buy odd things to mess around with. 11. The buff - indiscriminately buys random things that seem interesting, but usually doesn't have a lot of money. It is possible to run any item seen on the ebay auction through a mental filter and "psyche out" who the most probable buyer will be. This usually has great bearing on the price the item will inevitably rise to - usually in the last several hours of the auction on that item. With even casual observance of the kind of items that one might have interest in, one quickly learns which items will almost automatically bring a high price and which ones will bring a moderate price and which one will run through the auction bringing a low price if in fact rthey actually sell. The principle factors which determine the saleability and price of an item seem to be applicability, useability, physical condition, historic significance and relative scarcity. Relative scarcity seems to modulate the price more than anything else, followed by useability, and historic significance and it's a toss up which is the most important. Speaking soley for myself, I have found that most of the things of most interest to me are usually passed over and sell for rather low prices. This is especially true of tubes. Most people go after the tubes which have been hyped the most, ignoring many tubes which in fact are more useful than the ones which have been greatly hyped. Also, I have noticed - where tubes are concerned - that many very rare and at the same time very good and useful tubes - slide through the auction virtually un-noticed and can be purchased for a song. There are basically only two tube buyers: the collectors and the users. The users are looking for tubes which mostly fit commercial gear, be it old or new. The collectors are looking to fill holes in collections and for resale, but even they are more interested in "collecting" the most marketable tubes and seem to let other not so well known tubes pass by. So, there is a whole spectrum of tubes - including later television tubes which apparently few people want or are interested. Ironically, amond these - not so interesting tubes - there are some real jems, when it comes to homebrewing useable equipment and gear which is oriented toward the construction of 1930's to 1940's kinds of gear. It is also wise to carefully select search words and combinations of search words, since many items actually can only be found with certain search words and often seem mis-listed because of other descriptive uses of that particular search word. For instance, the search word, "receiver," will dredge up radio receivers, hair receivers weapon receivers, and little silver boxes with glass sides used to store trinkets and jewelery. However, it will recover any radio receiver listed as a 'receiver.' "Transmitter," will recover anything listed as a transmitter. But, "radio reciver," will recover only those items described by the seller as radio receivers. So, it pays to play with different search words and see what it is that they recover from the search engine. Once one gets into the "spirit" of the auction, it becomse a wonderful place to find what one needs, and to study things that one might not be able to study (in pictures) otherwise. I have seen many strange and rare tubes, as an example, that prior to that, resided exclusively as a number in my mind - something known of, but never actually seen. This is also especially true in the case of earlier model airplane engines, which I also track - but rarely buy. One can 'knock' the Ebay auction, but in full honesty, I feel that it will have a profound impact on every hobby endeavor, including Amateur Radio, and will inevitably severely compete with all other forms of marketing of used and even new things. It would not surprise me at all, to see it replace classified ads, flea markets, swap meets and the tradional ham swap-nets, as the preferred way to sell anything, which lends itself to cost-effective transportation from the seller to the buyer. (not a good place to sell old army tanks?) There is one rather somber note to the Ebay Auction, where ham radio is concerned. Right now and for the next few years there is going to be a surge of older ham gear and military surplus, dating from WWII. Then, this surge may go to a trickle, until the next generations of hams gets ready to go silent keys. Right now is a good time to pick up those old military rigs and many rare tubes. The next "round" of stuff may not be so plentiful and as useable. I am truly amzed at the quantities of things, which I thought would be rather rare that are showing up on the Ebay Auction. Especially older antique radios, parts and tubes. It's simply amazing to watch. Things which I have not seen since I was a young kid are suddenly showing up in fluxes that boggle the mind. And, the quantities of such items on the Ebay exceeds my expectations a thousand times over. In fact, many items touted as being "rare" are not rare at all, based on the numbers which are showing up in the auction. Now again, for the first times in almost a century these items are actually becoming so plentiful, that anyone who might have wanted one, could have one - at a price that is becoming more reasonable every day. -- Conrad, W7WLM From glowbugs-owner@piobaire.mines.uidaho.edu Mon Jun 28 15:30:44 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id PAA12217 for ; Mon, 28 Jun 1999 15:30:44 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id PAA19630; Mon, 28 Jun 1999 15:21:52 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id MAA13623 for glowbugs-outgoing; Mon, 28 Jun 1999 12:04:23 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from littontech.com (mail.littontech.com [209.77.76.11]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id MAA13613 for ; Mon, 28 Jun 1999 12:04:14 -0700 (PDT) Received: from littonengr.com (207.215.90.145) by littontech.com with ESMTP (Eudora Internet Mail Server 2.2.2); Mon, 28 Jun 1999 12:05:15 -0700 Message-ID: <3777C7DA.2003FB8C@littonengr.com> Date: Mon, 28 Jun 1999 12:07:45 -0700 From: Conrad Warren Reply-To: cwarren@littonengr.com Organization: Litton Engineering X-Mailer: Mozilla 4.5 (Macintosh; I; PPC) X-Accept-Language: en MIME-Version: 1.0 To: "Robert M.

That sounds very much indeed like the old sealed-arc transmitters, that ran an arc (and yes, carbon electrodes, I think) in a magnetic filed in some of the dee-darnedest environments; one version used an alcohol drip, I think, and I believe there were some that ran in hydrogen. Can't let *air* get to 'em, of course! Dunno why they used such stuff, maybe cooling--hydrogen has pretty good thermal conductivity, maybe better than air and an alcohol drip probably carries heat away as it evaporates, but that's just a guess. Excluding oxygen also prevents the electrodes burning away (and hydrogen is one of the gases it is *easy* to get in pretty pure form). Exotic stuff and not to be idly trifled with--and I think the big UHF TV rigs are spooky! Not hardly.

That is Dr. Valdemar Poulsen's arc converter. He was a Danish engineer(?) that took Duddell's ``singing arc'' used as an external heterodye radio frequency source, and made it into a viable low/medium frequency transmitter. That was around 1907-1912. They were commercially made until vacuum tubes took over around 1920. > Archie said it was basically a carbon arc such as is used to burn litho > plates > with, and the arc was pulled by a magnetic field and coupled through > some coil arrangement to the aerial.

Has anybody ever come across > one of these things? ( i'dve loved to see one in operation ) The arc has two electrodes, one carbon, that is adjustable, and one platinum(?) or platinized copper (and water cooled). It is burned in a strong magnetic field in a hydrogen atmosphere in a strong metal chamber. The hydrogen atmosphere was made with water dripped into the chamber. The arc, thus burned, is connected between antenna and ground and emits radio frequent energy at the natural period of the antenna, of continuous waves (thus its ``musical'' note when used with a beat or heterodyne or autodyne oscillating valve detector). I am not exactly sure of how the magnet works, but it is a DC field in a strong magnet that possibly holds the arc plasma together. Someone check Bucher or Sterling or other works to confirm that. Typically, they were used at waves shorter than Alexanderson alternators but below 200 meters. Most use was in the 300/450/600M marine waves. To key the arc converter, you use a dummy load or an inductor to detune the antenna to another wave (at a keying rate). The arc, once struck, stays on during operation. My OM, was also a shipboard op in those days, and recalled the ``musical note'' of those arc converters. He also recalled having to strike the arc, with care, else the electrode holder blew out into your hands, not a nice happenstance. Arc converters came in standard sizes, typically 2kw at the low end, up to 100kw (which magnet therefrom became the first Berkeley cyclotron and still sits on the campus somewhere). The 2kw sets were standard size marine sets of the period, and used until the WWII era, in remote places. Most arc converters in this country were made by the Federal Telegraph Company (later absorbed by Mackay and ITT [here in Raleigh] and now sold to some British company. One of the AWA members had a home brew arc converter that was supposed to run on 160M, at a meeting about 10 years back, but I missed its demo. I heard one of the members say that it was not supposed to work on waves that short. I dunno for sure. IFF it could work on 160M, it might make for an interesting CW rig.....(:+}}..... If magnets could be obtained and wound, and suitable electrodes and chamber fabricated, it is not that hard to assemble the needed parts. I would be real careful of striking off the hydrogen atmosphere. It is probably not all that dangerous, but might be unsettling. That is all I can remember, offhand, but it is coverd in Bucher or Sterling's or other 20's radio manuals.

Typical spark sets would have one tank oscillation circuit in the spark discharger circuit. Then the antenna would be inductively coupled with or without added series capacitance. By modern standards that would be rather crude, and could be much improved with several tuned circuits, perhaps. We all need a decremeter for our shacks, right? (hint... today we probably call it a wavemeter). In practice, it was a very precisely calibrated wavemeter with a field strength meter, and you measured the bandwidth or decrement of the spark wave by plotting the frequency and the meter output across the wave. See the end sections or possibly the appendix of Bucher around page 250 or so, and there is a neat plot of a spark wave and its decrement. As I remember Bucher's arc diagrams, they were directly coupled or maybe coupled with a 1 turn link. I need to consult Bucher, tonight. There was a good 1932 radio manual by Duncan and Drew, that has some diagrams and descriptions of the marine arc sets. Sterlings has some, but Loomis or Bucher seem to be the heavy hitters in details.

Well, let's see; you can coarse-tune a spark rig by the size, shape and distance of the electrodes, and probably by picking the RF freq at a harmonic of the applied AC or interrupted DC; that's step one. Step two, loose coupling into a tank at Fo. Come otta there into a wavetrap at 3Fo (especially with interrupted DC, odd harmonics wil predominate and for reasons that are intuitively obvious but take a few pages of math to explain, the first odd harmonic will be the biggest--there is one major-league squarewave at work here and if you take apart a squarewave you get a poetical succession of odd harmonics); another double-tuned, loose & variably-coupled transformer at Fo (or some other flexible topology, this one just happens to be both historically correct and low parts-count), and sniff it with a spectrum analyzer. Retweak the gap & interrupter for the cleanest sigs. At *that* point, either 5Fo or 7Fo will predominate, and probably take another trap. With a lot of luck, you might have an airable signal at that point; and likely to be greatly attenuated. It's not going to be frequency-agile. (The next term level-wise *should* be 5Fo but real-world parallels--the glonking sync pulse power-draw of a TV rig, f'rinstance--lean to 7x so I'm hazarding a guess). The whole lash-up calls for very careful and complete shielding, isolating each section from the others, or the RF will sneak right around. It will not look a lot like a spark rig, though you might sneak by with hardware cloth (so you could, at least, see the sparks).

Hmmmmm..... I didn't think about that back then. Just playing with radio & that simple spark gap. It sure tore up the AM band! How far I don't remember.

Federal was a San Francisco based company, with roots in Stanford. I believe there was a Federal installation in the North Bay area, possibly at Bolinas or Pt. Reyes. Historians can correct me on this. Either way, when the transmitter was decomissioned, Berkeley got the magnet, which, if I'm correct, Ernest Lawrence of Berkeley helped design. The magnet can be seen on the U.C.

Don't forget the MIGHTY RK-34, also called the 2C34, a twin triode with seven pin base and the plates coming out the top to plate caps. These tubes are floating around and have shown up a couple of times on the Ebay auction - once as RK-34's and once as 2C34's. They are also available from Vacuum Tubes, Inc., on the internet (jim@vacuumtubesinc.com), phone/fax (513) 385-3855, for $6.50 new! I have built a lot of transmitters with these tubes, which will run an easy 25 watts push/pull - push/push service, and make keen Jones push/pull oscillators, both crystal controlled and otherwise. You can drive one with a 6SN7 jones push/pull crystal oscillator, if you want to take it easy on the crystals. Jones used them for VHF self-excited oscillators up to a couple hundred megs or so. They are rugged, stable and friendly tubes. Remember in push/push amplifier service, the output is at twice the frequency of the input and NEUTRALIZATION IS NOT REQUIRED. And, these tubes shine in that kind of service. They are definitely a 30's period tube, which seems to have fallen through the cracks of Amateur radio consciousness. They require 6.3 volts of filament voltage at 800 mils, and up to 300 volts of plate power at80 milliamperes. They are listed under V27, in the older ARRL Radio Amateur's Handbook and the base diagram is Figure 70. Physically, they are about the same size as a 6Y6 ( same envelop) and run reasonably cool at rated power. I have also used them for push/pull tripler service, where they make efficient power triplers, feeding an antenna on 21 Mhz, using a 7 Mhz crystal in a 6SN7 Jones push/pull crystal oscillator. Cathode keying works very well and no key clicks were observed on the other end, even with the simplest cathode keying circuit (The key lead bypassed with a 0.01 ufd, at the fron panel jack and another .01 ufd disc across the cathode socket pin to chassis ground.)

You might want to try powering the Ameco with regulated plate and screen supplies (or at least regulation on the screen) to see if it still chirps. If it does, you're probably overheating, and therefore endangering, your crystals. If the chirp goes away, voltage regulation is the cause.

The magnetic stablized arc is not a difficult device to build - as long as one does not expect the mechanism to advance the arc rods as they burn off. Then, the design gets a little dicey. There are many carbon rods still available that would serve nicely in this application. The best of those available are used in motion picture projectors and short pieces can be obtained from just about any theater projectionist, if one simply asks for them. Generally, they are burrned down to about three inches in length but, that's long enough. Actually, one can build an arc transmitters whose rods can be adjusted from the front panel by turning an insulated knob, which advances a carbon rod afixed to a threaded screw. A neon sign transformer of about 12 - 15 kilo-volts will yield a 300 - 500 watt transmitter. These are readily available, too, from neon sign servie companies, who are always removing old signs and tossing the transformers, which are generally good. Also, can find them at flea markets and second hand stores. The small transformers, used in Bar liquor signs are of an ideal size and are easy to come by both used and new. The plate capacitor needs to have a plate spacing of at least 3/8 of an inch, but 1/2" is better for 15 KV. The tank coil can be wound out of solid #16 wire or one can use copper tubing which can be made self supporting, or nearly so. Keying is usually done by keying a relay in the primary of the high voltage transformer. The navy seemed to prefer the quenched arc, made from a stack of discs or plates - especially in their emergency transmitters and their smaller simpler transmitters. But, the carbon arc is easier top make and works very well. I built one as a kid and sneaked it on the air one night after I had contacted somebody with my AT-1, just to see if he could hear me. He did, alright! But, I never used it again, although I was sorely tempted on numerous occasions.

Don't get the two confused or use the terms interchangably! There is an enormous difference in the two. The "other" CW stuff before Vacuum tube oscillators was the Alexandersen Alternator.

Actually, 6146s were relatively uncommon as finals in published "beginner" transmitter articles. I'm guessing that this was so because the 6146 was a current tube for the Novice power level (and two will do 100 W out), and therefore about as pricy in dollars per watt as you could go. So even into the late 1960s we see TV sweep tubes and 1625s in 75-W (input) rigs. > (Dave Newkirk, are there any particular HBK years you can recommend > from your experiences?) I'm flattered that you consider me a source. :-D I think Jeff has his hands full of offers of suitable schematics already. There was one in the mid 1960s (the 1966 Handbook has it on pp. 185-189; 6AG7-6146B) and another in the early 1970s (6GK6-6146B). Psst: There's no reason to confine yourself to a two-tube transmitter if you want the best in keying. A three-tube rig, with the first tube acting as an unkeyed oscillator (you can key it if you like, of course), will let you achieve no-compromise key waveshaping with chirps and yoops and no backwave. 73, Dave Newkirk, W9VES dpnewkirk@home.com From glowbugs-owner@piobaire.mines.uidaho.edu Mon Jun 28 21:28:46 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id VAA12795 for ; Mon, 28 Jun 1999 21:28:46 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id VAA22536; Mon, 28 Jun 1999 21:19:49 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id SAA20918 for glowbugs-outgoing; Mon, 28 Jun 1999 18:05:57 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from mail.rdc1.nj.home.com (imail@ha1.rdc1.nj.home.com [24.3.128.66]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id SAA20913 for ; Mon, 28 Jun 1999 18:05:53 -0700 (PDT) Received: from cc328679-a.vron1.nj.home.com ([24.5.103.17]) by mail.rdc1.nj.home.com (InterMail v4.01.01.00 201-229-111) with SMTP id <19990629010514.PGZQ1309.mail.rdc1.nj.home.com@cc328679-a.vron1.nj.home.com>; Mon, 28 Jun 1999 18:05:14 -0700 Reply-To: From: "David Newkirk" To: "User Na4g Boatanchor Bob" , Cc: Subject: RE: GB> AWA and the 1929 rule, TTT?

The first announcements of metal tubes included the 6D5, a sort of indirectly heated 45 equivalent. It didn't stay in the lineup for long. But the issue of the 6D5 reminds me to inject here that if you want a really nice low-mu power triode with first-rate shielding, you can use a metal 6F6, 6L6, or 6V6 with its plate and screen connected. Likewise, you needn't feel locked into using a solenoidal coil that's grossly oversized for the job (as was traditional); a good toroidal inductor of suitable design will be far less prone to microphonics and the effects of nearby objects. 73, Dave Newkirk, W9VES dpnewkirk@home.com From glowbugs-owner@piobaire.mines.uidaho.edu Mon Jun 28 21:55:04 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id VAA12813 for ; Mon, 28 Jun 1999 21:55:04 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id VAA24604; Mon, 28 Jun 1999 21:46:08 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id SAA21836 for glowbugs-outgoing; Mon, 28 Jun 1999 18:34:37 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from orford.valley.net (orford.valley.net [198.115.160.32]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id SAA21830 for ; Mon, 28 Jun 1999 18:34:34 -0700 (PDT) Received: from lyme.VALLEY.NET (lyme.valley.net [198.115.160.11]) by orford.valley.net (2.5 Build 2639 (Berkeley 8.8.6)/8.8.4) with SMTP id VAA07737; Mon, 28 Jun 1999 21:33:55 -0400 Date: Mon, 28 Jun 1999 21:33:55 -0400 Message-Id: <199906290133.VAA07737@orford.valley.net> Received: by lyme.VALLEY.NET (blitz.valley.net) via SMTP from plainfield-175.valley.net id <8785510> 28 Jun 99 21:36:30 EDT X-Sender: Brad_Thompson@pop.valley.net X-Mailer: Windows Eudora Light Version 1.5.2 Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" To: "Roberta J.

The system I know of is x-V-y, where x stands for the number of RF stages before the detector, V stands for the detector, and y stands for the number of AF stages after the detector. I would guess that a usage like 1-1-2 would be a variant. (It's possible to use more than one tube in the detector, but that wasn't so common in heyday of this loose code.) Almost surely, the numbers stood for *stages*, not envelopes; a 6F7 used as a pentode detector and triode audio, for instance, would surely have been referred to as a 0-V-1. 73, Dave Newkirk, W9VES dpnewkirk@home.com From glowbugs-owner@piobaire.mines.uidaho.edu Tue Jun 29 00:40:14 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id AAA12920 for ; Tue, 29 Jun 1999 00:40:14 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id AAA04714; Tue, 29 Jun 1999 00:31:16 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id VAA24244 for glowbugs-outgoing; Mon, 28 Jun 1999 21:23:58 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from postal.indy.net (postal.indy.net [199.3.65.16]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id VAA24235 for ; Mon, 28 Jun 1999 21:23:54 -0700 (PDT) Received: from indy2.indy.net (root@indy2.indy.net [199.3.65.7]) by postal.indy.net (8.9.2/8.9.2) with ESMTP id XAA12506; Mon, 28 Jun 1999 23:23:11 -0500 (EST) Received: from localhost (rbarmore@localhost [127.0.0.1]) by indy2.indy.net (8.8.7/8.8.7) with ESMTP id XAA02656; Mon, 28 Jun 1999 23:24:47 -0500 (EST) Date: Mon, 28 Jun 1999 23:24:44 -0500 (EST) From: "Roberta J.

Somebody asked if there were any rotating parts (as in fast, motor-driven) to an arc, and the answer is 'no." ...However, please note that an arc rig emits an *undamped* wave! That's right folks, a good arc rig is legal as church on Sunday (or pick your own day and institution, we got lots of both). But tricker to do. Darned if I cannot find any photos; know I've seen 'em. Turns out my "Bucher" is really Rupert Stanley, "Text Book on Wireless Telegraphy," 1914. He covers arcana like the Goldschmidt alternator under "undamped waves," and just a smidgen on the arc. Both Stanley and Sterling make it plain that the arc is excited by *DC.* Yup, direct current, same kind of stuff Tom Edison sold Manhattan (a sweeter deal than $24 in beads, if you happened to be him--not so good if you lived there many years later). Yep, you lay DC on the arc and strike it up just like anything making pictures in the projection booth down at the Pantages (or the Rialto or whatever the movie show in Yourtown called itself; we had the much-missed and creepy "Egyptian," and just up the street from me, the "Vogue" and a zillion more). The electromagnet is in the form of a pot-core inductor (shaped like a hatbox for doughnuts), with the gap on the inside; top pole, we drip alcohol down the center, and the arc runs right across a diameter intersecting the poles; alcohol (you could use kerosene [paraffin, outside the US] but it smokes up the chamber more rapidly--some land stations used city gas!). Front electrode is carbon, the back is copper; cooling water is circulated above and below the arc chamber, which has a nifty little regulator arrangement to keep the gas pressure ever so slightly above atmospheric. Thus we now have a DC arc running in a hydrogen (more-or-less; it's really a hydrocarbon vapor, as Sterling points out) atmosphere. Just to make life interesting, the electromagnet is in *series* between the DC source and the carbon electrode, where it acts as a current-limiting choke and an RFC; the copper electrode is grounded. (Unless you speak the Queen's English, in which case you must earth it instead). You may wonder, "what the heck good is all that?" and the answer is, not much! Nope, it takes a resonant circuit to make it produce useable RF. Hook a seres LC between the carbon terminal and ground, and we'll go from there (we'll get our real "series C" in an interesting way, see below, so don't get a condenser out). Paraphrasing Sterling, as the arc starts, there is a considerable current-flow; and some of the current is diverted to the antenna-ground system (which he models, rightly enough, as a condenser) via a series RF inductor. The aerial charges up, arc current goes down proportionately, and the arc voltage *rises.* (I'm gonna be lazy here and invoke the conservation of energy to account for that). As the voltage goes up, the antenna robs more current until it gets "fully" charged (umm, there's a liitle Zeno's Paradox lurking here; turnover point is where current into the condenser has dropped so that Z gets substantially higher than the arc's impedance). Now the arc gets most of the current, it's impedance drops, and the antenna capacitance discharges back through the arc; this makes the whole LC circuit ring and as it crosses zero headed into negative voltages, that current opposes the normal flow through the arc and pfft, it goes *out!* And immediately starts up again (the LC is still ringing, you see, and heads back across zero in the other direction, where it aids flow across the gap). All the magnet-and-hydrogen does is make the arc *easy* to put out; hydrogen has a *high* rate of diffusion and the magnetic field acts on the arc (see "Singing Flame," I think a websearch might turn up some good/odd stuff) to increase path-length; something counterintuitive here but I *think* the weaker arc is more easily pulled away from the ionized atmostphere it exists in. Adjustment is likely critical--you can model this in a manner akin to that of a tube in Class C; the tube only conducts over a very small portion of half of each cycle but it's a great *big* slug of current, and as its period is conincident with that of the plate tank, the tank rings like a bell and we get simon-pure sinewaves (assuming we picked reasonably-high Q for that tank and took care to avoid unexpected modes). ..But in an arc, we get some work out of the "bottom" half-cycle of the ringing: it puts the arc out, and, unloaded, zings back the other way and helps to start it up again; and once the arc starts up, it dumps in another nice jolt of energy and thus the whole thing is self-sustaining. Sterling shows a number of ways to key it; the classic example of frequency-shift keying (with a chopper, no less!) by a loop coupled to the antenna inductor, but he calls that an "emergency method." He details a "dummy load" method, keying the RF back and forth with a contactor *ahead* of the inductor/aerial (another tuned circuit in the dummy load), and an absolutely Goldbergian stunt that uses one *more* electrode as an "ignitor" with a keyed solenoid to wriggle it--this one actually *does* turn the arc off and on as you key. All of 'em have a FSK chopper so the fellow with a damped-wave detector can copy 'em. Some of the older info in Stanley (op. cit.) shows the arc with RF chokes to feed in the DC and a series LC ckt across the arc (which it is in Sterling's too, but not obviously, as part or all of the series C is the antenna-ground capacitance*). He stresses that the arc must be short and thick (thus arc resistance is low), and if the arc's good, then F equals 1/(2*PI*SQR[L*C]), an equation that should be verrrry familiar. So in short, how an arc works is, it shock-excites a tuned circuit; and the tuned circuit quenches the arc at Fo thanks to some very clever shading of the odds. Small wonder you can't key the input power--it's a metastable system and takes a push-start to get going! Could you make it work on 160 meters? I don't know; it's probably pushing things, as the physical process of making the arc go out takes finite time. Somebody with a background in Real Fizzicks can probably make a better guess. 73, --Bobbi _______________________ * And--aha!--here's where flat-top antennas and multi-wire counterpoises are handy: we need enough C to keep L reasonable, and how better to do so?

The current flow meets resistance as the circulation in the tuned circuit changes direction and full cutoff is achieved by 'blowing out' the plasma with a steady state magnetic field resulting in one arc per cycle. To operate on higher frequencies than the maximum that the arc can be created and 'blown out' the only option is to pick a harmonic and filter the $h!t out of iit. Right so far????? Intrigued by the concept of blowing out the arc every cycle and the negative resistance attribute that makes the puppy work, one wonders if, rather than using a DC to make the field that blows out the arc and the plasma/tank circuit 'spring' to bounce the arc, one might use the same tank circuit to make the field that blows out the arc. This would save the energy used for the magnetic bias ala resonant TV flyback scheme, and rather than blow out the arc, perhaps one could 'train' it by having the two resonant circuits coupled a bit differently. My physics is very rusty but the idea is that, just maybe, we could operate at a higher frequency because now the field made by the tank is actually pusing the electrons in the opposite direction (stiffer spring) rather than just increasing the resistance. It might even train the arc into a 'string of beads' which would be kinda pretty to look at :-) Let's say the electron flow in the arc is from left to right on the page producing a toroidal magnetic field as shown (o's out of page, x's into page) o o o o o =>=>=>=>=> x x x x x now this mass flow of electrons is in a springy plasma/gas so we know the mass from the current and the springiness from the plasma/gas properties. We build a contradictory field by feeding this same current through a toroidal winding surrounding the electron current. dots and #'s represent the field built from the current in the toroid which is shown my dashes and arrows ->->->->->-> ^ o#o#o#o#o# | slice of toroid | #o#o#o#o#o v <-<-<-<-<-<- =>=>=>=>=> arc <-<-<-<-<-<- | x.x.x.x.x. ^ v .x.x.x.x.x | ->->->->->-> _____________ | | | _____ | | | | | | | X | | | |_____| | | | |_____________| end view of toroid with X representing arc electron flow into page, I did not draw toroid wire but consider the double box as the 'form' (don't really use a form) that the toroid would be wound on, i.e. wire If anyone has the physice background to model this, please let me know how high a freq we might expect this thing to work at.

Back in the 50's Motorola used them as power amplifiers tubes in their 450 Mc FM mobile radios. The 1981 ARRL handbook describes the conversion of the transmitter strip from one of these radios to use as a transmitting convertor for 432. A look through VHF handbooks from a couple of decades ago will likely yield a few construction projects for power amps at 432 or 1296.

Not really. The electrodes were adjustable, but there were no particular rotating parts. A motor generator was used to generate the magnet power voltage of several hundred volts dc. Caution --- When the arc is in operation the upper end of the loading inductor may be as much as 20,000 volts above ground and the operators should not approach to within six inches of the coil. Antenna current was rated at 7 amperes at 2400 meter waves on the 2kw Federal sets, but it would be much higher on the 100kw sets. The arc draws 8 amperes at starting on Federal 2kw rigs. Arcs were used on wavelengths from 300m to 18,000M, according to Bucher. The wave could be modulated by a coupled compensation loop attached to a key and a chopper, or keyed by a backshunt (dumping to dummy load) or frequency jump ``compensation'' (pulling the frequency several kc), or by an ignition key electrode that short circuited the arc from the antenna to a dummy load. The positive electrode (anode) connected to the antenna circuit and was a water-cooled copper tip electrode on a porcelain sleeve insulator. The negative electrode (cathode) connected to the ground and was also water cooled. So, a true carbon arc, was not used in commercial gear. Apparently, the copper electrode design was a Federal innovation. That would make it relatively easy to whip up electrodes, perhaps, for some experimental gear. Theoretical voltages can be 200-1200vdc (even storage batteries), but currents seem to be up to 10 amperes for 2kw sized sets.

The best part is that the rig acts in a familar manner, only working when the key is down; but it's a complex assembly. The "backshunt" method, using an SPDT RF relay ahead of the antenna inductor, is probably the most promising for practical (???) experimentation, as there's no backwave (the folks a few kc away appreciate this!) and any arc, spark and Tesla-coil fan can slap together such a relay from junkbox parts in a trice.

In the meantime I found some reference material and in Nilson and Hornung, "The arc flame must be subjected to a powerful transverse magnetic field to clear the ionized path as soon as possible." They have a diagram of the current and potential in various parts of the circuit and explain the starting and continous operation of the arc and explain that the inductance of the choke (if I'm reading this right) causes the emf from the antenna coil to discharge through the arc and restart it. So, my first thoughts appear to have been rather hairbrained, because the opposing magnetic field will not kill the ionization. You are probably right and I bet it's the chokes that limit the upper freq more than anything.

Thought I'd share it with everyone else. DISCLAIMER: The following information describes what works on MY TCS and in not intended to suggest this method/circuit arrangement is superior to any other! Connect one end of a 2.5MH RF choke to the 1625 grids where the two 22K grid biasing resistors intersect and remove grounding jumper. Connect a 1N4007 diode to pin 5 (grid) of the buffer 12A6 with the 'arrow' pointing away from the pin. Connect other end of diode to the just added RF choke at the end NOT connected to the 1625 grid circuit. At this intersection apply -150v to 'block' the buffer and finals with key up. When the key is down this point drops to -60v. My bias supply starts at -500v and through a simple network of high value resistors gets reduced to -150. These resistor values need to be calculated to match your available voltage supplies, ( a chance to exercise Ohm's law ). There is no 'power' involved in supplying bias voltage, so calculate for 1MA or less current flow in the circuit. You need to 'shape' the keyed waveform, so add a capacitor at the intersection of the diode and RFC. ( .01 works for my circuit values). This little mod allows the "Master" oscillator to run all the time. My TCS has a good external ground connected to the panel and I can just barely hear the oscillator on my own receiver. In other words, 'backwave' isn't a problem. 73 de W5FRS Dennis From glowbugs-owner@piobaire.mines.uidaho.edu Tue Jun 29 13:05:59 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id NAA13930 for ; Tue, 29 Jun 1999 13:05:59 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id MAA01939; Tue, 29 Jun 1999 12:56:36 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id JAA03265 for glowbugs-outgoing; Tue, 29 Jun 1999 09:38:42 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from weedcon1.cropsci.ncsu.edu (weedcon1.cropsci.ncsu.edu [152.1.207.51]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id JAA03259 for ; Tue, 29 Jun 1999 09:38:34 -0700 (PDT) Received: (from na4g@localhost) by weedcon1.cropsci.ncsu.edu (8.8.8/8.8.8) id MAA00338; Tue, 29 Jun 1999 12:36:39 -0400 (EDT) (envelope-from na4g) From: User Na4g Boatanchor Bob Message-Id: <199906291636.MAA00338@weedcon1.cropsci.ncsu.edu> Subject: Re: GB> carbon arc wireless --- ignition key method In-Reply-To: from "Roberta J.

As I understand it, the ignition key is an internal electrode with a power absorbing resistor that basically dumps the generator power to ground by short-circuiting the arc electrodes. Keying physically moves the ignition key electrode short, like a relay armature away from ground allowing the arc to strike. I would think that the positioning of the three electrodes would be important, since when that keying short is removed the arc must restrike itself. Rather than dumping the RF to load, the ignition key dumps the generator power to load. > The "backshunt" method, using an SPDT RF relay ahead of the antenna > inductor, is probably the most promising for practical (???) > experimentation, as there's no backwave (the folks a few kc away > appreciate this!) and any arc, spark and Tesla-coil fan can slap together > such a relay from junkbox parts in a trice.

Wonder if that's one reason for > full-duplex working in maritime MF CW comms?) Dunno, although I would expect that could be an issue. The arc was continuous, unless ignition keying was used, so probably it was struck when ready to send, and left running until traffic was passed. I doubt it would be left running for a full watch. That would consume a lot of power and electrodes. With Federal's use of copper for both electrodes, it would seem that one might be able to use something like ordinary welding rod or even bolts turned to a round end, as electrodes. I wonder how strong the case needs to be? Maybe something like large diameter iron pipe would work? The arc chamber is a water cooled bronze casting, on Federal models, and has a lid that will raise slightly in the event of an explosion to allow the seal to give a little and vent. The seals are sealed with grease. The chamber is vented to outside with a hose, through a one-way vent seal. A 15 gallon recirculating tank of water was used for cooling, with a small motor driven pump. On the Federal sets, the arc/magnet generator supplied 250-400vdc at 2kw (around 8 amperes --- wowser, a biggie current mg set). I don't exactly get how the magnet is positioned. It looks like coils are wound around the case of the chamber, but that seems to be mostly magnet. The actual chamber seems to be rather small, maybe the size of a coffee cup. The rest is all magnet and water cooling. Apparently, the ends of the magnet N/S poles were positioned on either side of the arc juncture. Sterling indicates that the anode tip should always be positioned midway between the magnet poles. On the carbons used on the cathode, they were 1/2 inch in diameter and 7 inches long, which seems like a standard lighting carbon? The copper holder positioned the carbon via a guage and special wrench. Although, I don't see how we could easily reconstruct a 2kw arc converter, I think there is enough there to run it down to maybe a 10 watt sized monster, and not melt the house down. Gee, what a winter's project it could be.

The resonant circuit is the antenna and ground/counterpoise. There is no tuned tank, although apparently one was used originally, but dropped in favor of just putting the arc across antenna and ground. Bucher (1917, Fig 278) shows a fundamental diagram which looks like a spark set with the spark capacitor and spark tank condenser physically swapped and then the arc from the generator to ground, thus..... + generator -------choke--+--capacitor--+ +----- ANTENNA | | | ARC coil coil | | | - generator -------choke--+-------------+ +----- GND Later, in Fig 279, he shows a ``modern'' arc transmitter, thus..... + generator -------choke--+----- ANTENNA | ARC | - generator -------choke--+----- GND Then, (p 266), he suggests ``In the latest naval installations, the arc gap is connected directly in series with the antenna circuit as shown in Fig. 279, which is a duplicate of the connections of the U.S. Naval Station at Radio, Va., and other naval stations.'' And, ``It is claimed that connecting the arc in this way has increased the range of such transmitters to a remarkable degree, and that the operation of the whole system has been simplified.'' It emulates the Alexanderson alternator hookup, in that regard. The ship sets seem to have the same connections. > The current flow meets > resistance as the circulation in the tuned circuit changes direction and > full cutoff is achieved by 'blowing out' the plasma with a steady state > magnetic field resulting in one arc per cycle.

But, the arc may not be totally blown out between oscillations, but only the plasma ion stream halted. Mention is made of blowing out the arc, and having to resstrike the arc when that happens. I am assuming that the plasma is affected but the burn is continuous. Sterling, (1st ed., p 397) seems to be saying that the RF inertia in the antenna circuit (inductive/capacitive reactance) allows the current to build up and decrease cyclically. The DC power supplied to it may be biasing it in some way, sort of like grid bias. The thump of starting the arc, probably is acting like the impulse of a spark hit. But, rather than generating discontinuous waves or damped waves, the arc ion stream allows the cycle to go continuously. It does seem to be an LC ringing phenomenon that generates the continuous wave after the arc is struck. I am expecting that the maximum frequency would be dependent upon the stray capacity of the arc converter, perhaps? Sterling suggests that sets could go to 450M on Independent Wireless Telegraph Company arc sets with no problems. > Right so far????? So far... .....interesting diagrams.... I don't think it is physically blown out, but the plasma is biased to cutoff or something like that, perhaps. > If anyone has the physice background to model this, please let > me know how high a freq we might expect this thing to work > at. Or maybe someone will build one and see... I think the oscillation frequency probably has more to do with the natural LC constants of the shipboard antennae and the actual apparatus.

The negative resistance effect depends upon having hydrogen in the arc chamber. Kerosene and alcohol are disassociated by the arc, giving hydrogen, and maximum frequency is limited by the gaseous conductor recombination time, which is fastest for hydrogen. I have seen (somewhere) a graph of conversion efficiency versus frequency, and it varied from maybe 45% at low frequencies to 15% at 600 Meters. These are actually quite good numbers, and compare favorably with tube and solid-state equipment. Arc converters were also noted for harmonic production, which is no surprise considering they were using only one tuned circuit. There is probably little chance of successful operation on 160M, but maybe a harmonic could be used - an interesting prospect! Also, they will work very well at 160-190 kc which may become a ham band within our lifetimes. We could theoretically do it now (at 160-190 kc) under Part 15 rules, but it would be hard to hold it down to 1 Watt. At LF, realizable antennas are a very small fraction of a wavelength and radiation resistance is very low, but what little power is radiated propagates VERY well. The Navy loved the arc transmitters; a 30 kW arc transmitter readily outperformed a 100 kW spark transmitter in field tests.

Let me quote from Peter Schroeder's excellent book, Contact At Sea (a wonderful history of maritime radio comms): (keep in mind he wrote this book in 1965 -- one year prior to spark finally being prohibited): "... The latest attention to the question of spark in maritime communications is seen at the Geneva Conference of 1959. In the Geneva Radio Regulations there is reiterated the previous authorization that a mobile station in distress may attract attention to its plight by any means available, which includes the use of spark if available and necessary. A new proviso makes its appearance at this point, where it is stated that `in exceptional circumstances' a land station may aid a mobile station in distress by `any means at its disposal.' That is to say, it could use spark, or broaden its radiotelephone or modulated CW (A2) emissions beyond the frequency tolerances specified and normally used. "At long last it appears that the terminal date previously sought for spark transmitters has been designated by the Geneva Regulations, bringing to a solution a problem second in importance only to that of obligatory intercommunications. It is categorically stated that Class B emissions will be allowed for distress calls and distress traffic only until January 1, 1966. By this time some thirty-nine years will have passed during which attempts have been repeatedly made to eliminate from maritime communications a mode of transmission rapidly reaching obsolescence, increasingly inefficient in the light of advancing technology, and a wasteful user of spectrum space. As indicated, this long process has been marked by the slow attrition of frequency assignments to spark stations, by imposing stricter technical requirements which spark could not meet, by the belated awareness on the part of shipping concerns that their own interests could best be served by communications equipment of modern design, and finally by outright prohibition." Schroeder fully details that 39-year struggle, which occured in conference after conference. I'll provide a summary of what transpired during each of those conferences in regard to spark. 73, Jeff KH6O From glowbugs-owner@piobaire.mines.uidaho.edu Wed Jun 30 07:09:30 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id HAA15192 for ; Wed, 30 Jun 1999 07:09:30 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id HAA15666; Wed, 30 Jun 1999 07:00:09 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id DAA16047 for glowbugs-outgoing; Wed, 30 Jun 1999 03:52:07 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from snipe.prod.itd.earthlink.net (snipe.prod.itd.earthlink.net [207.217.120.62]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id DAA16042 for ; Wed, 30 Jun 1999 03:52:02 -0700 (PDT) Received: from COMPUTER (ip124.winterpark.fl.pub-ip.psi.net [38.11.233.124]) by snipe.prod.itd.earthlink.net (8.9.3/8.9.3) with SMTP id DAA00048 for ; Wed, 30 Jun 1999 03:51:48 -0700 (PDT) Message-Id: <199906301051.DAA00048@snipe.prod.itd.earthlink.net> Comments: Authenticated sender is From: "Brian Carling" Organization: http://www.home.earthlink.net/~af4k To: glowbugs@piobaire.mines.uidaho.edu Date: Wed, 30 Jun 1999 06:50:47 -0400 MIME-Version: 1.0 Content-type: text/plain; charset=US-ASCII Content-transfer-encoding: 7BIT Subject: GB> GB on-the-air contest Reply-to: af4k@earthlink.net Priority: normal References: <377596A3.EB48B77A@littonengr.com> In-reply-to: X-mailer: Pegasus Mail for Windows (v2.54) Sender: owner-glowbugs@piobaire.mines.uidaho.edu Precedence: bulk Status: RO Having cut my teeth on the 40m novice band during the 6 months before they allowed reciprocal licensing for UK radio amateurs residing in the USA, (and having to invent a new callsign each week to avoid detection!), I can tell you that I very much miss the proliferation of chirpy, drifty, sometimes T7 signals one used to hear back then.

I have spent many enjoyable evenings browsing and studying, and tinkering with circuits at the bench. However, I'd like to suggest an idea: Why not develop a series of small projects, and provide several "tracks" simultaneously-- for example: 1. beautiful photos of vintage rigs, or copies of vintage rigs 2. construction information 3. circuit design information 4. results of on-air operations, hints-kinks, etc. 5. a "feedback" area, where folks can post their own views, experiences, etc. related to a particular project. For me, what I desire most, is to learn "why" every component was included in the design. Most articles in print don't go into the "why" very much. I miss that. I am a newby, and I am more interested in learning "why", than in just building a circuit and trying it out. That is fun too, but in my case my main goal is to learn how to design circuits of my own, or how to modify an existing design. With the "web site", we can actually provide all of the above, and let the user browse around, and dig into which ever "tracks" they are most interested in, and easily skip over what to them might be obvious or boring. And post questions about issues that haven't been covered in advance. Here are some examples of the sort of "design info" that I am looking to learn about-- "bypass caps", "audio shaping", "interstage coupling", "voltage regulation". "rf amp" stage, "mixer" stage, etc. By the way, I am aware that this sort of info is available in various places, but wouldn't it be nice, to be able to click on an area of a schematic, and have that portion of the design explained. What I find myself doing, is juggling several handbooks on my lap, nite after nite, trying to figure it out. thanks for your consideration, -bill AB4YD From glowbugs-owner@piobaire.mines.uidaho.edu Wed Jun 30 20:20:26 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id UAA16145 for ; Wed, 30 Jun 1999 20:20:26 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id UAA27571; Wed, 30 Jun 1999 20:10:49 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id QAA24773 for glowbugs-outgoing; Wed, 30 Jun 1999 16:58:28 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from mtiwmhc07.worldnet.att.net (mtiwmhc07.worldnet.att.net [204.127.131.42]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id QAA24768 for ; Wed, 30 Jun 1999 16:58:23 -0700 (PDT) Received: from SandyBlaize ([12.73.240.34]) by mtiwmhc07.worldnet.att.net (InterMail v03.02.07.07 118-134) with SMTP id <19990630235719.GTDW3470@SandyBlaize> for ; Wed, 30 Jun 1999 23:57:19 +0000 Message-ID: <003101bec353$ea2ef380$22f0490c@SandyBlaize> From: "Sandy W5TVW" To: "Glowbugs Reflector" Subject: GB> Canadian etc. allocations Date: Wed, 30 Jun 1999 18:53:58 -0500 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.1 X-MimeOLE: Produced By Microsoft MimeOLE V4.72.3110.3 Sender: owner-glowbugs@piobaire.mines.uidaho.edu Precedence: bulk Status: RO -----Original Message----- From: Sandy W5TVW To: Bill Griffith Date: Wednesday, June 30, 1999 18:52 Subject: Re: GB> Date spark finally outlawed > > >>Hi Sandy (and all); >> >>At 10:15 99/06/30 -0500, you wrote: >>>I don't know where the Canadian sub band stops. 3550 perhaps? >>>Anybody know? >> >>Here's the "official" 80m band plan from the Radio Amateurs of >Canada >>webpage at : >> > >Many thanks!

What's interesting to me is how relatively early on radio amateurs cleaned their houses of spark. In the United States, spark was expressly outlawed only well after hams had alredy stopped using it; the beginning of the its regulatory end occurred when, in 1924, US hamdom received new frequency assignments--at 80, 40, 20, and 5 meters--in which spark was left out of the list of authorized emissions. Also of interest to me is this: Considering the arguably amateur-hostile regulatory climate of the years immediately following World War I, we were lucky to receive a great (and surely unintentional) gift from the US authorities as we made the transition from spark to continuous wave: even though continuous wave was, input watt for input watt, considerably more efficient than spark, *the power limit for continuous wave operation remained at the limit (1 kW input) already in place for spark.* Had the regulators really had their wits about them, they might have lowered the input power limit in the new, continuous-wave-only amateur allocations to keep us on a commensurately shorter leash. 73, Dave Newkirk, W9VES dpnewkirk@home.com From glowbugs-owner@piobaire.mines.uidaho.edu Wed Jun 30 22:15:31 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id WAA16234 for ; Wed, 30 Jun 1999 22:15:30 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id WAA03675; Wed, 30 Jun 1999 22:05:57 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id SAA26386 for glowbugs-outgoing; Wed, 30 Jun 1999 18:55:33 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from pacs03.infoave.net (2610507E@pacs03.InfoAve.Net [165.166.0.13]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id SAA26380 for ; Wed, 30 Jun 1999 18:55:27 -0700 (PDT) Received: from pentagrid ("port 1032"@[207.144.106.166]) by InfoAve.Net (PMDF V5.1-12 #23426) with SMTP id <01JD0YVKZUS6A9QIOX@InfoAve.Net> for glowbugs@piobaire.mines.uidaho.edu; Wed, 30 Jun 1999 21:54:16 EDT Date: Wed, 30 Jun 1999 20:54:19 -0500 From: Conard Murray Subject: GB> forwarded message To: GlowBugs Message-id: <000701bec364$a2ec65a0$a66a90cf@pentagrid> MIME-version: 1.0 X-Mailer: Microsoft Outlook Express 4.72.3110.1 Content-type: text/plain; charset="iso-8859-1" Content-transfer-encoding: 7bit X-MSMail-Priority: Normal X-MIMEOLE: Produced By Microsoft MimeOLE V4.72.3110.3 X-Priority: 3 Sender: owner-glowbugs@piobaire.mines.uidaho.edu Precedence: bulk Status: RO Don't reply to me.....

If someone says his Globe Scout is "running 70W," we don't ask if he means Input (probably), or output power (surely not). We never dream of asking if Effective Radiated Power (ERP) is specified. It doesn't matter, anyway, if we can hear him, and ithe issue tends to lead to arguments. Twenty years ago the QRPers fought it out, decided wrongly, and persist in the error. Here are the words of one of the winners: "[W]e have long known that input power is no criteria for judging...what the circuit can deliver to the antenna." Weiss, A. (K8EEG, then), "Simple and Accurate RF Power Meter," Ham Radio, Oct., 1973 p 26. The answer to that was, sure, that's right, but Input power is easy for the newcomer to meaure and, besides, it puts a premium on improving circuits if you can run all you can get at a given power input. That view was shared by the British low power fraternity, but the output power folks here won a suspect election and the Brits changed over for comity. Since then (1980 or so) the case for measuring what we take out of the power supply, to the final usually, has not been made. But it is worth restating: The fellow with the $7.95 Radio Shack VOM can tell you what he is feeding his final, but the price for even a low power kit Wattmeter starts at about $100. Moreover, if you are good at tinkering with circuits to get more power to the load, you get to keep it in any Watt Input system. If you go by Watts out, a one-tube Hartley using an 813 is the same as a push-push 40m signal from an 80M VFO as long as they bend the bimetal the same distance. So it is a good idea to be polite, still, but if someone asks how we should measure power, tell 'em, "Input, of course, so it can be a hobby for anyone." de ab5L, michael in dallas, MNHopkins@JUNO.com Student of Tecraft, ICM and Six Meters' Golden age: 1957-58 Box 226841, Dallas, TX 75222 Banned for life from QRP-L mailer for various truths.

Now that you mention it: There were some hams in the period around 1925 who were working with arc and operated entirely on harmonics. but they were working with an arc that ran between tungsten electrodes. They wrote a paper for QST in 1925. Allen Miller has a copy of that article, he sent me a copy a few years ago. Alan is at the Wireless and Steam Museum in Massachusetts. I will have a look for the article. A teacher at City College New York named Lester Israel had a diagram published that showed" how amateurs can operate on "short waves"with the the arc." I tried his circuit a few times but was never able to get the advertised results. I will have a look for the Israel paper. Regards David Quinlan Ken Gordon wrote: > > Hello Ken!

Amateurs knew quite well that they had everything to lose if they didn't embrace change (memories of trying to get back on the air after WWI were fresh on their mind). OTOH, the maritime industry had never felt the threat of losing frequencies (every international conference resulted in favorable results for them); in many ways the industry had a rather arrogant manner of thinking, believing wireless was created exclusively for its use. In conference after conference, the industry argued that it couldn't financially replace spark with CW -- the monetary figures to upgrade the industry were presented at each meeting, and smaller maritime nations said they'd be especially hit hard, monetarily. Remember, change within the ITU came about only through ballot, while change within a nation (The FRC and amateur radio) was swift and usually one-sided. Thus, we see provisions for spark lingering within the maritime industry to 1966. 7.3W, Jeff KH6O From glowbugs-owner@piobaire.mines.uidaho.edu Fri Jul 2 01:39:01 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id BAA18070 for ; Fri, 2 Jul 1999 01:39:01 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id BAA22896; Fri, 2 Jul 1999 01:29:08 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id WAA13676 for glowbugs-outgoing; Thu, 1 Jul 1999 22:15:38 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from phnxpop1.phnx.uswest.net (mail.phnx.uswest.net [206.80.192.1]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with SMTP id WAA13670 for ; Thu, 1 Jul 1999 22:15:33 -0700 (PDT) Received: (qmail 25326 invoked by alias); 2 Jul 1999 05:14:18 -0000 Delivered-To: fixup-glowbugs@piobaire.mines.uidaho.edu@fixme Received: (qmail 25292 invoked by uid 0); 2 Jul 1999 05:14:17 -0000 Received: from dialupq136.phnx.uswest.net (HELO asu.uswest.net) (209.181.111.136) by phnxpop1.phnx.uswest.net with SMTP; 2 Jul 1999 05:14:17 -0000 Message-ID: <377C4AAF.BD580D4E@asu.uswest.net> Date: Thu, 01 Jul 1999 22:14:46 -0700 From: Will White Reply-To: wcw@asu.uswest.net Organization: Hartley, Pierce, & Colpitts, Ltd.

This is similar to the argument being made by the wireless telephone industry lately for why they need Federal laws against manufacture and sale of scanning receivers capable of receiving the cell portions of 800 MHz. THey say it is too expensive for them to go to using an encryption scheme! For shame! Why is it, in the Teens or Nineties, big business invokes the catachism of Free Enterprise/Market {sic}, except where the market operates in their disfavor: then they are only too happy to have government regulation!

I believe AM would be targetted before CW. If CW were ever banned, I think there would be more bootleggers (utilizing that banned mode) on the ham bands than ever before... The argument for keeping CW is that it's really the only mode in which equipment can readily be built by the average ham, thus helping us to abide, in part, by S97.1: 97.1 Basis and purpose. The rules and regulations in this Part are designed to provide an amateur radio service having a fundamental purpose as expressed in the following principles: (a) Recognition and enhancement of the value of the amateur service to the public as a voluntary noncommercial communication service, particularly with respect to providing emergency communications. (b) Continuation and extension of the amateur's proven ability to contribute to the advancement of the radio art. (c) Encouragement and improvement of the amateur service through rules which provide for advancing skills in both the communications and technical phases of the art. (d) Expansion of the existing reservoir within the amateur radio service of trained operators, technicians, and electronics experts. (e) Continuation and extension of the amateur's unique ability to enhance international goodwill. If CW ever comes under threat, we could form a loose association with FISTS and QRP-L -- that in itself would result in well over 2,000 hams conducting a letter-writing campaign (of course, tens of thousands more would be just as vocal). I'm proud of the fact that we're now the only radio service capable of utilizing this mode. That certainly makes us unique!

I doubt the FCC would take any requests to outlaw CW, or even AM, seriously. For the most part, CW and AM operation is transparent to SSB operators. AM is so rare, and there are many SSB ops who couldn't tell a CW signal from a heterodyne anyway. Ham radio is nostalgia for some, cutting edge experimentation for others. Emergency service is part of the ARS too. There is room for everyone, except the few little piggies who want it all to themselves. But the arguments, if anyone is making them, for phasing out modes that are less than up-to-the-minute are specious as far as the ARS is concerned. After all, we aren't talking about maritime, commercial, and military radio operation, where ultra-modernity is vital to save lives and money.

And, if they did, they would have to get it by the FCC, who, incidentally, happens to be one of the best friends that Amateur Radio has, today. And, they would have to get the cooperation of the WARC, which might not be so easy, in lieu of the fact that amateur radio is more popular in other countries than it is here - judging from the efforts of the member nations of such conventions and conferences. I wish more hams would spend less time worrying about their spectrum and more time using it. Worry has never helped anyone do anything. But, action speaks louder than words. Congress is moved by statistics. Dead bands always look statristically bad and all the words in the world won't help. And, it doesn't hurt to let your representatives know how you feel. If you feel concerned, do somethng about - find a dead band and work it back to life. A routine spin across the spectrum, from 1600 KHZ, to 20 Mhz, reveals great gobs of spectrum that is almost totally abandoned. There are few users, since many uses have transferred to satellite communications systems (or something else, like fiber) people want "reliable" communications channels - not solar impacted noisy radio. I am will to predict that if there are any users left in the lower radio bands, at the end of the 21st century it will be the last few hams using up the last of the surviving 6L6's. I think that it is pretty obvious that the hams will loose everything above 100 Mhz, within 25 years, but with the mediocre uses they are making of these higher bands - due to repeaters and channelization, so what? It seems apparent that the hams are going to get more spectrum shortly than they have ever had, and I expect that trend to continue. and for one very simple reason - for every kilo-hertz of spectrum there is below 100 mega-cycles, there is ten mege-cycles of useful spectrum above 100 mega-hertz - actually, much more than that. In the next twenty years, advanced microwave technology will push the frontiers of microwave to well above 70,000Mhz, although much of this spectrum is what I call "blue sky spectrum." Even in the Soviet Union, there were hams, who had CW and (as far as I know) voice capability. All through the "Cold War" years, they could talk to us. Isn't it a little strange that (theoretically) the most suppressive government and ideological social structure would allow hamming, and that hams, who live in a "free" society should be worried about loosing their amateur radio priviledges? What's wrong with this picture? Another last thought. Even a casual glance at "Industry" will reveal that "the Capitans of Industry," have never been interested in anything unless it looked like a sure deal and one that could be maneuvered into some form of water tight monopoly - like wire communications, fiber - even microwave. But, radio? Hah! Even J.P. Morgan realized that radio could never be owned and why? Because the signals travel by themselves and nobody can control them, once they are launched. That was why he refused to support Tesla's "atmospheric power distribution schemes." Even the most serious attempts at "jamming" are never completely successful. And, I imagine that the US Governments hopes of being able to control propogation via Haarp technology has failed sufficiently to indicate to them that they need to spend more money in other ways. Radio is the sociological mercury that has always slipped through every body's fingers. That is why there is a big push to grab the "High" ground, so to say.(Notice that no one is trying to forbid listening to short wave, like they are UHF and Microwave.) The Amateur Hams and the Indians have always had two things in common: they started out with the most furtile ground and ended up with the least. But, "fertile" is a frame of mind, as was demonstrated when oil was struck on the Indian Reservation in Oklahoma, after the turn of the century. Same old, same old. But, the nice thing is, that what makes the lower bands fun, challenging and interesting to work, makes them a nightmare for the communications business man - the guy who wants all communications to flow through his hands and he wants in for 15% - forever! This guy is the antricipated problem. But, another way to look at it, is, that shortwave is not reliable enough for him, anymore. He wants something better - and he's found it - UHF, Micro-wave and Laser communications. So, relax - if there was an urgent plot to take away ham radio, it would simply happen - boom, done! Just like tha ban on fireworks, cigarettes guns and drugs, and we all know how really successful these programs are! Right?!

A bare-bones CW transmitter can have a lower parts count than a bare-bones SSB transmitter, but if you're capable of reading a schematic and soldering together parts, an SSB transmitter is just as buildable, even without PC boards, as a CW rig. It will probably be *more expensive* as a result of the necessary sideband filter and will take more time to build, but it will not be *less buildable.* (As for what an "average ham" is, I welcome trustworthy data.) And then there's AM, a bare-bones transmitter for which can be just a CW transmitter augmented by an audio power amplifier -- also eminently buildable by *anyone* capable of reading a schematic and soldering together parts. My late uncle had a saying: "You don't need a license to build things; your FCC license is for *operating*." And he was right. Yes, the amateur radio service is one of the few services, perhaps the only service, in which an operator can operate with self-built equipment that isn't subject to type acceptance. But at least in this country, *building, testing, and troubleshooting* one's own ham equipment can be done *without a license* (a dummy antenna is necessary for transmitter tests; antennas can be tested in receive, or with low-power test equipment for which a license is not required). To put it another way, nearly all of the "build radio gear yourself and learn by doing" territory we traditionally and self-propagandizingly claim for amateur radio demonstrably *isn't* really our territory because it is demonstrably accessible to *anyone* interested in radio, licensed or not. The only time an amateur radio license is legally operative is when its holder is *operating* a transmitter that emits a signal, at a frequency allocated for amateur radio use, that is sufficiently strong to require identification by the callsign printed on the license. 73, Dave Newkirk, W9VES dpnewkirk@home.com From glowbugs-owner@piobaire.mines.uidaho.edu Thu Jul 1 11:04:17 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id LAA16949 for ; Thu, 1 Jul 1999 11:04:16 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id KAA28513; Thu, 1 Jul 1999 10:54:34 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id HAA04265 for glowbugs-outgoing; Thu, 1 Jul 1999 07:37:34 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from tntech.edu (SYSTEM@gemini.tntech.edu [149.149.11.7]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id HAA04260 for ; Thu, 1 Jul 1999 07:37:29 -0700 (PDT) Received: from tetrode ([149.149.42.10]) by gemini.tntech.edu (PMDF V5.2-32 #30682) with SMTP id <01JD1NEZQ5W48WXRFS@gemini.tntech.edu> for glowbugs@piobaire.mines.uidaho.edu; Thu, 1 Jul 1999 09:37:05 CDT Date: Fri, 02 Jul 1999 09:39:15 -0500 From: Conard Murray Subject: GB> web site proposal To: glowbugs@piobaire.mines.uidaho.edu Message-id: <01c401bec498$a8ac74a0$0a2a9595@ece.tntech.edu> MIME-version: 1.0 X-MIMEOLE: Produced By Microsoft MimeOLE V5.00.2314.1300 X-Mailer: Microsoft Outlook Express 5.00.2314.1300 Content-type: text/plain; charset="iso-8859-1" Content-transfer-encoding: 7bit X-Priority: 3 X-MSMail-priority: Normal Sender: owner-glowbugs@piobaire.mines.uidaho.edu Precedence: bulk Status: RO Mornin' everyone, I think Bill has a good idea here.

Very good point, Jeff. I think that if CW bit the dust tomorrow ( as a requirement ), it would result in an elevation of that mode. In spite of all i read from the no-code people about how there's no need for it, CW has always held a mystique all it's own, and not just with the communication folks. I have had more than a couple digi-maniacs tell me " . . . well, morse code, well, that's more like a language . . .) In my small mind there is no catagory to put CW into ; it is it's * own * discipline and art. It is that mystique that keeps it alive. Some may think it will die out with technology, i think it has a life of it's own. Besides, if it weren't for CW, how would the world be saved in " Independence Day " ? :>D *** Small bit of trivia: How did T. A.

I believe you're giving that "average ham" a bit too much credit, and are also dismissing the parts count as something of little importance. I think today's average ham will be more attracted to the 20-component transmitter over a 200-component transmitter, especially when that average ham has only an average junkbox and an average amount of time to search for and order speciality components. Our average ham also only has an average collection of test equipment, and an average knowledge of trouble- shooting (every CW transmitter I've ever built worked the first time I powered it up -- not so with the more complex gear I've struggled with). Maybe we should look at what hams are building today. If kit manufacturers are any indication, we see a huge number of CW kits being offered FS, but hardly any phone kits. Considering that what's being offered by the manufacturers reflects upon what folks desire to build, it would seem that phone kits are just not popular. > (As for what an "average ham" is, I welcome trustworthy data.)

"Well, since a conventional wisdom has not developed, yet, for me to parrot, I'll just fall back on Professor Pangloss and say that the Administration must know what it is doing by invading the Vatican." "Human rights are foremost in the New World Order, and time will tell." "What a fool!" Frank snapped as he pulled the plug on the chassis of an ancient Admiral and shorted the filters with a clip lead and a screwdriver. "I remember when he was a promising young reporter, but now he's banished to Sunday morning talk shows." "It's like he wanted to be overlooked." As Frank began to pull the 21 mc IF parts from the old black and white, I settled back in repose on a rusting 388 case. I pulled a Ralph W. Emerson that morning by skipping church to avoid Communion, and Frank tossed his off Saturday at Our Lady. Frank, an ex choirboy in addition to being leader of a Five Meter Liberation Army to take back 56-60 mc, skips when out-of-town troupes bring a non Latin Mass. My kids were being ecumenically shuffled on cross-faith visits and Christie, Frank's chief bodyguard, attended All Apologies Unitarian with her boyfriend, Press, so she could join the gun control debate. Only Frank and I were in the basement as the other bodyguard, who I call the WARmon, was upstairs teaching Christies' pet ferret to attack Texas' 10-gallon water bugs. Frank's interest in TV is sporadic. We don't have one and his trailer, where he spends less time than in our basement workshop, lacks even a broadcast band radio save the special coils for his Super-Gainer RX. But he pulls a lot of junkers down for parts and especially likes the pre mid-1950s sets for their 21 mc intermediate frequency. He once had me build a VHF front end from a Standard turret tuner, but now he re tunes the cans for 12 Meter transmitters. When TV moves up from the bottom six channels, Frank reasons, he can pull the TXs up to 28 mc and push-push to 5 meters with any big twin triode. Untill then he operates them on 25 mc and jumps up to 6M. You'd think someone would notice his 80-100 kc wide modulated oscillations on the Magic Band, but he stays above 50.125 and no one catches him. If he inches up into Channel 2 and puts a herringbone on Sesame Street, the Feds drive down the street in a Crown Victoria with an antenna. "Barney's Brigade," the WARmon calls them, and they have yet to find Frank's unshielded pair of 250 THs. "So Frank," I asked searchingly (just talking to my 1930esque pal seems to bring out Tom Swifties), "How is today, at the end of the century," different from the Depression Era?" I expected the usual recitation about character and adversity but, to my surprise, he said: "Not at all." I must have looked puzzled because he motioned to a breadboard on the bench and said, "just listen." This was another of his regens, I could see. He names them and this one says "Bobbi" on its panel, which has silver foil on the back to shield the 34 and pair of 19s from hand capacity. It was a 0-V-2 in the parlance of its day as it had no RF amp, a detector and two stages of audio to a pair of Baldwin 'phones. I cranked down the bench supply to 2 volts and fed it 135 more from a Lambda in a nearby rack. I walked up the pointed black regen control and searched with a Type B dial for signals. An old voltmeter read 32 when the feedback went critical, without a 'pop,' and I could hear signals. I was looking for another pair of 'phones when Frank said, "just listen" again. What a mess. I could hear AC on most of the signals when I could keep them in the Blooper's passband. With some difficulty I was able to copy one of the errant ECOs at least enough to learn it emanated from a Hartley. There was no mention of the TX's tube type and his RX was said to be a 1-V-2. He wandered out of range and a chirpy Colpits, or something, came by with the OT signing, I think, "8GZ." No one was giving a name but everyone reported QTH. I did not listen long. The funny keying was troublesome, like when Frank uses his hacksaw blade sideswiper, and I have never mastered the trick of copying one sig out of five without a direct conversion RX to let me zero beat the worst offender. Since it was broad daylight, I assumed the coils were for 40M, but I suspected a trick. I cut the voltages and looked under the wooden base for a tape recorder input, but found only some wing nuts and mismatched fasteners of all sorts. Frank calls Electric Radio magazine "a pitiful pit of form-over-function priggism," and they would not want to picture his home brew style, thank you. One does not ask an obvious question of Frank, so I continued to consider the cacophony carefully after replacing the probably perilous potentials prudently. In seven monitored QSOs I heard one commercial allusion. Someone had a "Super Wasp." I heard Frank's favorite 210 tubes, literally, all over the band and I was glad when the WARmon broke my concentration by setting down the red eyed weasel. "She ate three and bloodied a Malamute in four attempts," he said. I wondered what Sgt. Preston was doing in Dallas. Then the tattooed skinhead turned to Frank and let the ferret, as it were, out of the bag. "How is that ADA contest, Frank?", he asked revealingly. Of course he meant Antique Wireless Association, but maybe ADA fit too. All the OT sigs seemed to have marked disabilities. de ab5L, michael in dallas, MNHopkins@JUNO.com Student of Tecraft, ICM and Six Meters' Golden age: 1957-58 Box 226841, Dallas, TX 75222 Copyright FMLA XLIII From glowbugs-owner@piobaire.mines.uidaho.edu Sat Jul 3 11:49:17 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id LAA19494 for ; Sat, 3 Jul 1999 11:49:17 -0400 Received: from bigboote.WPI.EDU (root@bigboote.WPI.EDU [130.215.24.2]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id LAA02820; Sat, 3 Jul 1999 11:38:58 -0400 (EDT) Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by bigboote.WPI.EDU (8.9.3/8.9.3) with ESMTP id CAA15046; Sat, 3 Jul 1999 02:37:16 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id XAA01223 for glowbugs-outgoing; Fri, 2 Jul 1999 23:24:39 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from mtiwmhc06.worldnet.att.net (mtiwmhc06.worldnet.att.net [204.127.131.41]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id XAA01218 for ; Fri, 2 Jul 1999 23:24:33 -0700 (PDT) Received: from SandyBlaize ([12.73.240.207]) by mtiwmhc06.worldnet.att.net (InterMail v03.02.07.07 118-134) with SMTP id <19990703062315.HSXW9368@SandyBlaize>; Sat, 3 Jul 1999 06:23:15 +0000 Message-ID: <007d01bec51c$358de380$4cef490c@SandyBlaize> From: "Sandy W5TVW" To: "Glowbugs Reflector" , "Gary G Johanson" Subject: GB> Re: Super Gainer and chirp Date: Sat, 3 Jul 1999 00:45:05 -0500 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.1 X-MimeOLE: Produced By Microsoft MimeOLE V4.72.3110.3 Sender: owner-glowbugs@piobaire.mines.uidaho.edu Precedence: bulk Status: RO - >By th' way, i was listening to 20 mtrs on the super gainer this morning >at >6:00 eastern, and there were a lot of DX from the Pacific.

A field Signal Battalion consists of three companies, each with special communication services within a combat division. Company A is known as the Radio Company, Company B as the Wire Company, and Company C as the Outpost Company. Unlike so many combat line companies, the Outpost Company is not made up of civilians from all walks of life. The majority of personnel consists of telegraph operators, lineman, and telegraph and telephone technicians. The rest are unbranded mavericks usually thrown in at the last minute to bring the company to full complement. The telegraph operators come from the railroads, commercial telegraph companies, and press news services. Among them are train dispatchers, wire chiefs, experts, and third-rate artisans who go through life classified as "lids". The experts were born this way, and the lids never get any better. Telegraphers make a strange fraternity that borders on the eccentric, consisting of a veritable army of nomads. In their strabge and mysterious devotion there is an unyielding class distinction which divides them from boomers, floaters, and home guards. A close study of the specie reveals the best of them to be idealists dreaming of greener pastures just over the hill. The bravest, and often the best, are afflicted with a strange malady called "foot-itch", and drift along with the tide bucking the extra board and keeping a few steps ahead of their creditors. The boomers, consisting chiefly of lids, are the most boisterous of the lot, and take great pride in admitting they have "flagged" on every railroad in the company during their relentless dodging of sheriffs and loan sharks. To work under an assumed name seems to impart a certain degree of craftiness to their mental behavior. They know each other intimately "over-the-wire", although they may be meeting physically for the first time. I have oftem wondered if Samuel Morse realized when he invented telegraphy what a strange breed of cats he was to turn loose on society. Their every waking thought is of telegraphy and they live in a strange world where the clicking of the sounder is like unto the trumpet of the Angel Gabriel. To them telegraphy is the highest form of art, and like musucuans, they belong to a class considered erratic outside their selected realm. Of all the signalmen they are the most clannish, and like to mix only among themselves. They can be seen promenading in little groups or gathering in ginmills, all reminiscing at the same time and speaking a jargon only they understand. Telegraphers are never crapshooters, the sport being too strenous or below their dignity. They will often indulge in a friendly game of poker among themselves for low stakes. Their playing of poker is often a sham, merely a means of getitng together, and very little money changes hands during the lull in their strange expressions. The linemen are are the rough an ready lot, or the boys that wear the number 44 tunics and size 6 hats. Occasionally there is a great runt among them, but he is usually looked upon as a kind of mascot, or the recipient of their horseplay. Linemen are boys who refuse to grow up, and are selected to their craft solely from the measurement across their backs. these pole climbers usually stick together come hell or high water, and it's a rare instance when military policy bring a group of less than six of them at a time. They cling together like birds of a feather, and their antisocial aspect is not of their own choice. There worldly knowledge is centered on pole line work, and their total conversation is related only to that which has to do with cutting phantoms, hanging loadcoils, and stringing wire. Telegraphers and technicians shun them like the plague; they are too rough and full of fun - no telegrapher or technician would dream of mixing with them socially. Thet judge fellow linesmen by their speed and ability in climbing poles, and some of them are rather fancy Dns. Thet gather in the ginmills where they feel very much at home, and between elbow bendings they set poles and string wire far into the night. I have heard that more miles of pole lines have been built in these French bistros than any place on earth. Unlike the telegrapher who is violently attached to his art of telegraphing, the lineman takes great pride in demonstrating his physical prowess, whether it be the scuffling of fellow-signalmen or the guzzling of great quantities of rum at one time. Linesmen are all natural-born crapshooters, and to them "Ada from Decatur" and "Nina from Dinah" are living symbols. Very few of them go in for poker due to the mental hazards of the sport, or the fact that they are easy prey for the professional slickers. The telephone and telegraph technicians are more of the studious type and are looked upon as the boys with the single-track minds. Their every waking thought is of telephone and telegraph circuitry. And fellow-signalmen are inclined to consider them as necessary evils, or the boys who have somehow managed to escape the butterfly nets. They never agree among themselves, and each of them has devised a special circuit that will eventually revolutionize the communications industry. They gather in the ginmills not to partake of the essence of the vine, but to argue over the merit of some new circuit. French bistro keepers have learned to spot them from the wild look in their eyes, and once they are seated there is a hurried removal of tablecloths before they become criss-crossed with the heiroglyphics of their frenzied minds. These technicians are constantly drawing new circuits, or testing instruments, or killing time in mental gymnastic that produce a phony atmosphere. The lineman, whose work produces much sweat from the brow, is prone to look upon this environment as a maleficent scheme of gold-bricking. He syas nothing, but in the back part of his head he knows he will have his day. The poles are set and there is wire to string, and there is always a shortage of groundmen. Nothing pleases the line sargent more than harnessing a technician to the stringinh reel/ These are gala days that bring forth almost a fiesta spirit, and over the hills of old Lorraine is heard: The Song of the Lineman: The sound of the saw, that mighty claw Opening the way for the sun to the soil. The digging of holes, the setting of poles Is the groundman's contribution to toil. But the greatest desire is the stringing of wire, And the lineman climbs and shouts for joy; Bucking the reel over stream and field\ Is the task that separates the man from the boy! The technicians are compelled to stick together for self-preservation as the lineman are too rough and the telegraqphers look down their noses at them. The unbranded mavericks, unable to classify in any of the special crafts, become steady and reliabel groundmen. Those of slight physique are assigned to the pigeon detail where they become entranced with the love-life and habits of these noble birds. Our signal company has its share of knuckleheads, slickers, phonies and goldbricks. A knucklehead is an honest and hard-working boy who is placed in this classification by the others simply because he lacks the skill of getitng out of work. HTey seldom grumble or complain, and this demeanor has caused them to be classified as dumb. The slickers are the ones that turn first sargant's hair grey and they appear in all the groups. They are born with the instinct of a fox, taking short-cuts and shifting the menial tasks to fellow-signalmen by every ruse and strategem. The phonies are a slight bit off their rocker, and suffer from hullicinations; they are usually little fellows wanting to be mental giants and afraid they will be overlooked in the shuffle. No one, with sincere apologies to the psychologists, has entirely figured the goldbrick, and the common conception that he is lazy is certainly misleading. He will perform more genuine labor getting out of work than the actual task involved. He is a rebel at heart and. like the common house cat, refuses to be bossed.

Thanks to everyone who responded about the beam filter. Not sure what version I have--seems to be ex-Navy (US) from the "U(anchor)S" stamp, has two 1/4" output jacks, a flying-lead input plug (PL-55 marked "1136-1 UTC") and an angled front panel marked for either way up mounting (horizontally or vertically, I presume). No extra terminals on the internal connection strip, so it is either 4K or 600R and the only way to find out is to try it! Panel is labelled "BEAM FILTER" at the top, "N. A. F. 68304" and a serial number at the bottom. Nice little case, modern accessory filters should be so solid and clean. ...And for those who suggested an active filter, I have built and used 'em and find them not really well-suited to Morse work, or at least simple ones aren't, especially plugged in to the output of a receiver. Too prone to do annoying things when overdriven and they call for knocking the level down and than hanging an amp on the output, way too much stuff for a simple job. (Pat Hawker shows a neat one in the latest set of Technical Topic reprints; but it's not suited to these lists without subbing a dozen tubes for the original active devices; a tube comparator, you don't wanna build! Or maybe you do if you have a lot of free time). (Yes, there are plenty of ways to make an active filter act nice, both subtle things per Deane Jensen and overtly simple ones like a clipper at the input and real audio amp--6V6, LM380, something with some oomph--at the output, but that's fancier than I'm looking for). My old set-up, which I may yet clone, started out with a nifty clipper (three switchable steps--1N34s, 1N34s, 1N4007s) and then the filter, nothing more than a 5mH RFC & condenser tuned to about 700cps with small condensers to top-couple the signal in and out. Worked well, despite a likely-crummy Q. The clippers whomped the noise bursts most severely and the filter took away the clipping artifacts while making sigs near Fo stand out. Lost it one of the times I moved house. If I can dope out the beam filter, adding a stepped clipper will be easy. (Advantage over the continuously-variable ones? No batteries! ...Though a triode starved for plate volts will do a very fine job here as well). Next topic! Does anyone know what happed to the "Rag Chewer's Club?" Used to be the easiest wallpaper to get; received one under my first call about a week after going on the air! The '97 HB still talks about the award but you don't see 'em on hamshack walls any more. :( It would seem a natural for tube-fan on-the-air gatherings, you can't hardly swap the dope about your rigs, haze each other over keying & note and so on in much less than the required half-hour. 73, --Bobbi KB9GKX "RJ" rbarmore@indy.net Roberta J.

Think i had to apply for membership with ARRL or something; but nobdy i knew then had RCC either, and there was never any talk about it with the eriudite stiffs on the club machines then, so i just let it go, like so many other things.

If I were in charge of QST's Hints and Kinks column--which I was, for something about eight years--I, also, would reject a hint about using spiral-binder wire for general-purpose inductances, for the reason that because it's steel, the Q of inductors made with it is *terrible*. I admit that it can work well if you're trying to quash an unwanted resonance, as in a parasitic-oscillation suppressor for the low (say, 160 through 40 m) bands--I've used it for that purpose myself. But even at those frequencies, a few inches of that steel wire in a circulating-current path will introduce measurable loss compared to copper wire of the same length. > But as an example, the '56 rig calls for a 40 MEL plug in coil.

I believe I saw someone mention this nomenclature in passing in the Boatanchors within the past couple of weeks, and some elements of it appear to be elegantly simple: JEL mentions "Junior ("75 W") with end link"; JCL means "Junior with (fixed) center link"; JVL means (uh-oh) "Junior with variable center link." My 1959 Allied Radio catalog also mentions the "Baby" series (no power/voltage ratings given), which I think B & W considered as "mini" in naming its members: MC (center-tapped, no link), MEL (mini with end link), and MCL (mini with center link). 73, Dave Newkirk, W9VES dpnewkirk@home.com From glowbugs-owner@piobaire.mines.uidaho.edu Tue Jul 6 22:08:55 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id WAA23636 for ; Tue, 6 Jul 1999 22:08:55 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id VAA30139; Tue, 6 Jul 1999 21:57:33 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id SAA20832 for glowbugs-outgoing; Tue, 6 Jul 1999 18:43:42 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from smtp6.jps.net (smtp6.jps.net [209.63.224.103]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id SAA20824 for ; Tue, 6 Jul 1999 18:43:38 -0700 (PDT) Received: from compaq (209-239-194-155.oak.jps.net [209.239.194.155]) by smtp6.jps.net (8.9.0/8.8.5) with SMTP id SAA09135; Tue, 6 Jul 1999 18:42:29 -0700 (PDT) Message-ID: <01dd01bec81a$4dfec640$9bc2efd1@compaq> From: "Mike Silva" To: "Brad Hernlem" , Subject: Re: GB> Regulator Circuits Date: Tue, 6 Jul 1999 18:44:31 -0700 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.1 X-MimeOLE: Produced By Microsoft MimeOLE V4.72.3110.3 Sender: owner-glowbugs@piobaire.mines.uidaho.edu Precedence: bulk Status: RO I'd guess they should be fine. On the subject, one thing that's kind of hidden in the fine print regarding such circuits is the large voltage difference that can exist between the heater and the cathode. Normally I doubt we give much thought to the heater-cathode rating of tubes, but in this case you must pay attention to this rating. This is why the heater transformer for such circuits was usually referenced to a voltage other than ground -- the top of the VR tube was a common spot. This way the heater-cathode voltage for the amplifier tube is zero, while the heater-cathode voltage for the pass tube is reduced by Vref. The 6AS7 dual triode pass tube has a 300V rating, making it very useful for such service. Most of the other tubes used as pass tubes seem to have a 180-200V rating, but note that sometimes the early production tubes were only rated for 90V, with this rating rising in later years. For example, both the 6L6 and the 6Y6 in my 1946 Sylvania manual are only rated at 90V, though they're twice that in later manuals. 73, Mike, KK6GM >The ARRL Handbooks show regulated power supply circuits using 6L6 or 6Y6 >type tubes for the series regulator tubes.

The JCL and JEL have their links wound over the tank coil, at the center and end respectively. The JVL puts the link in a gap of about 1/2 in. at the center of the tank, which consists of two series-connected sections; thus the link's coupling can be varied to an extent. In the case of the 20 JVL, there is a sixth terminal, from a tap two turns from one end of the tank, to a pin mounted outboard from the nearest mounting eye. The 40 JVL lacks this tap. I also have a few Bud coils that resemble the '40 JVL' construction. Their part labelling was apparently similar to B&W's, but began with "O." My catalogs describe the "Junior" as 75W, 850 V, able to take the output of an 807. The Bud coils are also rated for 75W. The "Baby" coils were rated at 25W. The 75W coils were to be offerred in my '42 Allied Radio Catalog, all three styles by '53, only the B&W lines by '56.

Just came back from visiting some of the old stomping grounds around Daytona and Dunedin ( east and west coasts, respectively: i think Florida is the only state in the lower 48 where you can watch the sun rise and set over ocean ) and as i checked out what was left of the lighthouses, i wondered why no mention was made in the literature concerning these structures abt the radios installed therin. These sentinels were largely closed up after the war, and certainly maintained a radio presence at least from the twenties through the late thirties. I remember the antenna masts in ruin as a kid. I know there are indices of operating lighthouses across the U.S. but i wonder if there is a roster of associated frequencies that were used? Wouldn't it be cool to do a field day from one of these things?? ****************************************************************************** ********* As for the trivia question, about Al and Mina ( the Thomas Edisons ) How did he propose to her under the constant scrutiny of her folks?

An arc is not a relaxation oscillator. A spark sort of is. Put the arc where C1 is, and put C1 in series with the secondary tank, perhaps, would make it closer to an arc in operation. When I saw him mention sawtooth waveform, that told me it was not operating as an arc should. An arc is supposed to generate sine waves. You can replace the arc electrodes with a pair of points and it will be an ordinary spark set. I would sense that allowing the tank circuits to flywheel might smooth out the sawtooth and make it more sinusoidal. If so, that would mean it might work on 160M. But, it is a very interesting idea and approach to generating waves.

Enjoy. 73, Mark, AB0CW ------------------------------------------- Yes, the acid test is in listening with a receiver. A spark transmitter generates damped waves, and will sound like anything between keyed static to a fairly musical note, without the BFO. An arc transmitter generates continuous waves and may have some arc hiss on it, but requires a BFO for reception.

It's the 12GC6, which appears to be a 12DQ6-A with a different pinout. The 6DQ6/12DQ6/etc family was a very commonly used sweep tube, and ended up in a lot of transmitters as well (there were also lots of compactron and other versions -- just look for sweep tubes with 17.5 or 18 Watt plates). Anyway, the good news is that AES is selling the 12GC6 for all of a buck fifty. There are lots of other good buys on the flyer, but this is the one that caught my eye. BTW, the 12GC6 is even cheap when it's not on sale -- around $2.50 to $3. 73, Mike, KK6GM From glowbugs-owner@piobaire.mines.uidaho.edu Fri Jul 9 14:59:31 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id OAA28207 for ; Fri, 9 Jul 1999 14:59:31 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id OAA24567; Fri, 9 Jul 1999 14:59:24 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id LAA29823 for glowbugs-outgoing; Fri, 9 Jul 1999 11:37:16 -0700 (PDT) Received: from localhost (keng@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with SMTP id LAA29798; Fri, 9 Jul 1999 11:37:09 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: keng owned process doing -bs Date: Fri, 9 Jul 1999 11:37:09 -0700 (PDT) From: Ken Gordon X-Sender: keng@piobaire.mines.uidaho.edu To: User Na4g Boatanchor Bob cc: glowbugs@piobaire.mines.uidaho.edu Subject: Re: GB> This Weekend's 30/40/80/160M QRGs?????

Old Snuffy, the comic hillbilly of "Barney Google and Snuffy Smith" back when newspapers just had one color ink, liked to grab the poker 'stakes after shooting out the light. And his caplock was but a short step from the WARmon's Tech 9 that darkened a room as he backed out the door thru which his boss Christie pushed Frank. The skinhead sprayed the ceiling again and the last fluros fell among the 9mm cases in a Wagnerian darkness. The only pieces of unbroken glass were on Frank's breadboard. Frank, my pal who wants to take back 56-60 mc with a Five Meter Liberation Army, meant well. He really just wanted to encourage the home construction and understanding of radio devices like he did before 1938 on 5 Meters. But the unrequested bodyguards who attached themselves to him are, well, humorless when it looks like anyone is going to harm their pal. Frank does communications for their WAR social club, for the Nation of Islam, and for anyone who has an anti-government slant. He never forgave the Feds for outlawing modulated oscillators on 5M. But this time we were just taking in a suburban ham club meeting. Frank sets his browser to call him to his KayPro when the term "homebrew," or "home brew" + "contest" appears on any amateur radio mailer or website. He saw a posting for a QRP transmitter contest and thought he had a chance, even though his pair of 45s on pine lost to a Pack Ratt board kit mounted in a wood box at the HamCom regenerative RX contest. So Frank went all out and we drove to Irving, Texas, which is the home of the Dallas Cowboys who are not in jail at any given time. The ham club over there has a nice meeting room in a cafeteria, but we never really got to try the cuisine. Truth is we did not get past the registration table and it was not just because of the bodyguards. In fact, Christie is quite presentable. She is 20 something and carries a baby bag that says "Nite, Nite, Baby." Don't ask what's in it. You cannot see her tattoo, but her backup is covered with them. He has a shaved head, red muscle shirt, suspenders and jackboots plus a ring with a skull on it and it does not help a bit that he carries a huge dictionary sized book with a craft paper cover that says, "Therman, last ed." Still, we usually get in places as I look like any other worn out 50-something guy with a white beard and Frank is positively natty in double breasted brown suit with shoulder pads, Navy last shoes and spats. But the woman with the little sticky name tags that say "Hello, my name is," took one look at Frank's offering and called a KA5-something who asked, "What are those?" He was pointing at a 50L6 and 25-something. It was not a good sign. Frank explained he had built up a MOPA with a full set of plug in coils from 160 thru 5M. Frank ignores non-harmonically related bands and did not have time for a 12M/6M rig too. He showed them the coils in an Admiration Coffee can as an Old Timer wandered up and pushed thru the crowd to get a better look. Seeing the non polarity line plug, he said,"No transformer," and the KA5-something asked how it could work without one. When Frank said there was a fine transformer right outside on a the pole, the OT laughed and explained that Frank had the filaments in series with a dropping resistor and was using a voltage tripler for about 400 volts of B+, no load, direct from the line. A couple of Neon bulbs operated as voltage regulators and a 25W bulb so old it actually said "Mazda" on it took the initial surge. The OT cautioned about plugging in the cord the right way and Frank showed him a pocket line tester. But after an animated side discussion, the folks decided Frank could not enter because of insurance fears. That led to a spirited conversation in which, I fear, some things were said that many might now regret. And the menacing WARmon, as I call the skinhead, made the registration woman nervous. She said "Officer?" to a passing security guy so obese he could not throw Christie out, or even the red-eyed white ferret who was peeping out of the baby bag now. But Christie did not even look around. She does not like police of any type so she shouted "Time's a'waistin'" and the WARmon opened the book. The thing inside looked mildly like my Tom Corbet Space Cadet raygun and flashlight, but it made a lot more noise. I covered my ears as he hosed down the ceiling. We headed for the door but were met by a pair of policemen. One of them said, "Everybody back inside." "Were they're shots fired?" "Yes there were," said Christie, stepping up to the big cop. She showed him a picture ID saying she was a field rep for Handgun Control Inc. "We were illustrating the devastating effect of these immoral firearms and now I've got to go to the car for more copies of a Congressional Record speech by Senator Kennedy." "Would you like one, too?" she asked as the cops pushed past us. "Commie," I heard one say. The Irving Police are pretty good and might have caught us had not Christie simply driven down the block in Frank's Frazer and parked behind a Denny's. We went in for Frank's favorite "California Dreamin" sandwich and the WARmon joined us after parking his Toyota Land Cruiser in a closed car lot next door and affixing a pair of signs that said "One Owner" and "Nosotros Financiamos." As the ferret growled over the skin from the "all white" chicken order the WARmon insisted on, Christie called her boyfriend to bring her Lincoln, just in case. We rode home with him after they finally took the barricades off US 183. I opined, as we turned onto Loop 12, that I hoped this experience at least taught us something. There was a silence, but finally Frank said, "Yes, I think you're right." "There are some situations in which a transformerless power supply might not be the best route." de ab5L, michael in dallas, MNHopkins@JUNO.com Student of Tecraft, ICM and Six Meters' Golden age: 1957-58 Box 226841, Dallas, TX 75222 Copyright FMLA XLIV From glowbugs-owner@piobaire.mines.uidaho.edu Sat Jul 10 08:06:43 1999 Return-Path: Received: from smtp.WPI.EDU (root@smtp.WPI.EDU [130.215.24.62]) by blargh.wpi.edu (8.9.1/8.9.1) with ESMTP id IAA29047 for ; Sat, 10 Jul 1999 08:06:42 -0400 Received: from piobaire.mines.uidaho.edu (root@piobaire.mines.uidaho.edu [129.101.8.252]) by smtp.WPI.EDU (8.9.3/8.9.3) with ESMTP id IAA19773; Sat, 10 Jul 1999 08:06:24 -0400 (EDT) Received: (from domo@localhost) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) id FAA12405 for glowbugs-outgoing; Sat, 10 Jul 1999 05:02:02 -0700 (PDT) X-Authentication-Warning: piobaire.mines.uidaho.edu: domo set sender to owner-glowbugs using -f Received: from postal.indy.net (postal.indy.net [199.3.65.16]) by piobaire.mines.uidaho.edu (8.8.3/8.6.12) with ESMTP id FAA12400 for ; Sat, 10 Jul 1999 05:01:59 -0700 (PDT) Received: from indy1.indy.net (root@indy1 [199.3.65.5]) by postal.indy.net (8.9.3/8.9.3) with ESMTP id HAA26016; Sat, 10 Jul 1999 07:02:08 -0500 (EST) Received: from localhost (rbarmore@localhost [127.0.0.1]) by indy1.indy.net (8.8.7/8.8.7) with ESMTP id HAA25452; Sat, 10 Jul 1999 07:03:32 -0500 (EST) Date: Sat, 10 Jul 1999 07:03:31 -0500 (EST) From: "Roberta J.

I am missing pages 51 through 54, the cover, and any pages after 72. This book has some interesting circuits and tube descriptions in it. Page 54 describes a neat little VFO transmitter which uses an 802 as the VFO tube followed by an 807, on 160,80,40,20 and 10 meters. Page 57 starts the description of the RCA Economy Transmitter, which uses a 6L6 Tri-Tet crystal oscillator followed by an 809. (This particular book uses Tri-Tet crystal oscillators practically exclusively). Page 59 starts a description of an RCA-815 UHF Transmitter, covering 2 1/2 through 20 meters, complete with modulator (another 815) and power-supply. Page 64 describes the RCA SIngle-Control 360-Watt Transmitter: 6V6-G driving an 813. The 6V6 gets its plate voltage from the screen of the 813. Neat idea. Lastly is the RCA 5-Band Plate-Modulated 'Phone CW Transmitter. 450 watts CW, 310 watts 'phone, 10-160 meters. Push-pull 812s in the finals, push-pull 811s as modulators. Does anyone have a copy of this book from which they could copy my missing pages?

That's what I got here too. The above was shortly after 2300Z, then silence from both stations til after at least 0000.

Truly the end of an era. It's been a long and honourble run since before the Titanic to the age of video telephones and internet communications over HF radio (the same frequencies used for morse code) with ships at sea. A proud history marked by proud Radio Officers whose dedication to duty saved many a sailor's life. Morse code is still used at the Globe Wireless HQ via MF (500 Khz) and HF facilities at New Orleans (WNU) and San Francisco (KFS and KPH) to serve some ships that still use CW. Some because they missed the GMDSS deadline and some because their modern equipment has failed and the Radio Officer (now often serving as an Electronics Officer) has fired up old equipment to solve the immediate problem. It is surprising how often this happens. We, at Globe Wireless, intend to offer a CW service via our US based stations for as long as there is a real need. We are very fortunate that we have wonderful and exciting new uses for the HF frequencies that have served us so well for so many years. We welcome comments from shipping companies, ships and all interested parties. If you foresee a specific or general need for CW service, please let us know. The following frequencies are currently available. KFS/KPH 500 4274.0 Call on channel 3/4 8444.5 12 16 WNU/WCC 4 Call on channel 3/4 8 12 16 All of the regular services are still available.

I would expect CLA to be there for a while, since they run a lot of third-world ships out of there. As long as they don't make port in a GMDSS country, or stay out of the USCG's way, they probably will be keeping the CW for some time to come. I would expect some of the SA countries and African/Asian countries to do likewise, for a while longer, in the backwaters. Some of the Cuban/SA ops will rattle an' bang like the breeze on their bugs and keyers.... a nice round of code to hear, at speed. Also, WLO is still running CW tfc lists and wx bcsts on the odd hours (0100/0300/0500, etc) on 4343, plus others (http://wloradio.com) and we might want to monitor what o' Mobile Marine Radio is doing. I dunno if they are manning a CW position, still. The wx is not the full navtex like it used to be, but is still good cw copy. It seems to be just an automaton sending. After 0000Z last night I did some serious scanning of the marine bands, for call tapes, and heard about 25 or 30 call tapes going on 4/6/8/12/16/22mhz. Not too many there, though. I will put a list of QRA/QRG's out if I remember to bring it in. So, all hands listen up tonight, too, just in case we had the raday off by one......(:+{{.....

Also found some links to a material using the same name which is allegedly GLycerin and PhThALic anhydride, also used for high vacuum seals. Is this the same stuff? Is there any good reason NOT to just leave the windings uncoated? I did some preliminary tinkering with this idea (the HV supply idea, not failure to use insulating varnish idea) by taking an old horizontal hold coil (the one with apparently several thousand turns of approx. #35 wire) and adding a hundred turns of #24 wire next to the fine windings (there was room on the form adjacent). Feeding the 100 turn winding with my Heathkit RF generator, I watched the output of the fine winding on my oscilloscope. There was a peak at about 180 kHz (about 20 V P-P out for less than 1 V in). I am assuming that this is the natural resonant frequency of the output winding with its distributed capacitance. The plan is to create another winding on the form so that the 100 turn winding will be part of the plate circuit of an oscillator (with caps to tune to 180 kHz) and using the final winding to feedback to the grid. Does this sound workable? Brad >Glyptal is a trade name for a General Electric company insulating product >that can be >purchased in arosol or liquid ..

Yup - according to what Dick says, it is tonight (Monday). Below is part of his message sent to the Boatanchors reflector: From: Dick Dillman In my posting a couple of weeks ago I mentioned that the Globe Wireless stations, the last coast stations in North America to use Morse, would be closing down their Morse operations on Monday, 12 July. I now have the time and frequency information for that event that many readers asked for. The call signs involved are WCC/WNU which will be keyed from Lousiana and KPH/KFS which will be keyed from Half Moon Bay, CA. I use the term "call signs" instead of "stations" because in the cases of WCC and KPH, formerly the calls of the two great RCA stations on the east and west coasts, their original transmitting plants were shut down years ago. Still, it will be your last chance to hear these calls on the air. The official beginning of the event will be at 1600PDT (2300Z) with messages from WCC/WNU followed by messages from KPH/KFS with the final sign-off at 2359Z. However certain personal or organizational messages may be sent from KPH/KFS beginning at 1500PDT (2200Z). So my advice is to start your listening watch a little before 2200Z to make sure you hear everything. WCC/WNU 500 Kc. 12826.5 Kc. 17117.6 Kc. KPH/KFS 500 Kc. 8444.5 Kc. 17184.8 Kc.

This is from a 1966 QST. This is a 1-tube (12AU7 or 12AT7 or 12AX7) audio amp and audio filter combination. Between the two tube amplifier halves is an audio circuit with two resonated LC circuits. The resonators use those ubiquitous 88 mH toroids, and a switch can lift one resonator connection out of the circuit, for when the user wants less selectivity or less ringing. There aren't too many parts, and this looked like a simple place for me to start on my superhet.

Also, I caught a real autoalarm from VCS, back about 5 years, when the M/V Salvador Allende went down. Someday, long after we are gone, someone might find such things interesting, perhaps.....

Let us make sure we get the copy exact. I know I am picking at nits, but it would be good to get the formalized record copy, as it would have been received, and not as automatons might have received it. If you look carefully at the copies, that are posted, you will understand what I mean. I noticed what might be errors not by the sending operators, who did make some sending errors due to the emotion of the time, but also on the receiving end. Sandy, Jeff, Dick and others help out to make sure all is correct. Someone has some of the bcsts online at http://hfradio.org/lastmorse.html I hope he can put them all there for us to use and enjoy. I don't have a wav player, so I cant run them on my NT machine, yet. I will recheck carefully my tapes from last night to make sure I get it exactly right, as a cw operator would have copied it and written it down. It may be good to have the as-sent copy, with errors, and the record clean copy, etc. Who actually has readable tapes of all the goings on? Mine run from about 2200 on, scanning the 5 given frequencies, but I sure wish I had thought of 4310 like Sandy did. WCC/WNU was only QSA 1 here on 17117, and nil on 12886. KFS/KPH was QSA5 on 17178 and nil elsewhere. 600M was nil. Thanks all, and remember, this is history we have had the fortune to hear. ZUT DE NA4G/Bob UP Afterthoughts......

I dunno exactly how transparent, though.... a few hundred feet maybe. You could use hydrophones to send morse. I dunno what the DX would be but it should be a few miles. They can hear subs at several miles or more. Whales' songs can be heard at 100 miles or more. It would probably take a lot of audio power and transducer power to get DX, but it might be doable, and my expectation is that folks have probably tried that kind of thing in the Silent Service. Any pig boat folks around to add some insights? I will check with my neighbor, an old diesel fleet boat op (whose boat was the one that was sunk at dockside in Buenos Aires durinig the Falklands conflict - ex Sea Cat, I think).

A sad/memorial day. I worry about the future of maritime communications. We have most of our eggs in one basket: satellite communications and the SITOR stations really don't have enough traffic to survive financially, in the long run, without government support. I don't really see Globe Wireless (KPH/WCC/WNU) and Mobile Marine Radio (WLO/KLS) being around 10 years from now. On most of my voyages, even though deck officers have the new GMDSS licenses and are now doing much of the communications work, they often don't understand what they are doing. The GMDSS false alarm rates still exceeds 95% due to transmission errors, improper forwarding of DSS transmissions, etc. Either the deck officers make the mistakes themselves or they get exasperated and turn the equipment off. Thus the reliablility of the GMDSS system for ships that are truly in distress is being compromised. This has been a subject at internatinal conferences but no one wants to "rock the boat" and admit that the GMDSS system isn't perfect and that a licensed WELL TRAINED operator is still needed. Cost savings are the orders of the day. It will take a major maritime tragedy before this is truly addressed. To answer your question: Last year, when I got my GMDSS license, the FCC was still offering the commercial radiotelegraphy licenses thru the volunteer examination system. It may have changed by now but I doubt it - I've heard of no regulatory changes and the FCC is always slow to react. 73, DougLas Losty/WA1TUT (ex-maritime Radio-Electronics officer and ex-owner/operator of WKM/West Haven, CT Radio).

The end came yesterday. We knew it had to come. But the end had been predicted so many times for so many years while Morse soldiered on, paying no attention, providing good, reliable service for decades after it was declared dead... maybe some of thought the day would never come. But when KPH/KFS signed off the air for the last time yesterday it was the end of commercial Morse in North America. It was a sad day but one I knew I couldn't miss. Tom Horsfall, WA6OPE and I were invited along with many others to be present at the Half Moon Bay master station of Globe Wireless from which the final messages would be sent. I held in my hand two messages I hoped to have transmitted. They were messages of greeting and farewell from the Maritime Radio Historical Society and the San Francisco Maritime Historical Park - typed of course with a mill on historically correct Mackay Radio radiogram blanks. I secretly dared hope that I myself might be permitted to send these messages. I brought along my favorite straight key in its carrying case and my radiotelegraph license just in case. I have visited KFS many times over the years. On my first visit the operating room had nothing but Morse positions. Over the years the number of computers steadily advanced as the Morse positions retreated to the west end of the building. When we walked in yesterday both sides of the operating room were lined with racks holding sleek black computers and monitors. And way down at the end was the one remaining Morse operating position. Tom spotted him first... Paul Zell, the morse operator on duty. We knew him by his green eyeshade. All real radiotelegraph operators seem to wear green eyeshades. Pictures I have taken at KFS and KPH decades ago show men in green eyeshades at the key or the Kleinschmidt. Pictures taken at those stations decades before that show the same thing. I am convinced that there is a secret ceremony of the green eyeshade in which the distinctive headgear is carefully placed upon the head of the operator newly welcomed into the fraternity. This is of course a ceremony we have not been permitted to witness, a ceremony that will never again take place. I sat down next to Paul Zell as we listened to Russian and Cuban ships calling their respective coast stations. I realized that true to its nature, Morse will carry on in other parts of the world even after the keyes in North America are finally silent. I had to ask Paul the question... "How are you feeling about today?" An impossible question to answer but he answered it. "CW was my life," he said and turned back to the receiver. More people started to arrive, a surprising number of reporters among them. But the real dignitaries in my eyes were the radio men and women who knew they had to be there on this day. Jack Martini, manager of KPH when it shut down (he intentionally left the receivers on when he left). Ray Smith, the operator who sent the farewell message when KPH at Bolinas/Pt. Reyes shut down. John Brundage, manager of KFS in its golden age of Morse. Denise, the first female coast station operator on the west coast. Rex Patterson, chief engineer at KFS in its glory years. And many more. We swapped stories and I showed them my photo album. We ate from the delicious spread of food provided by Peter Kierans of Globe Wireless. But our eyes kept glancing at the clock. It was now less than two hours to the end. I finally screwed my courage to the sticking place and asked Tim Gorman, Director of Operations, if my messages might be sent and if, perhaps, I might be permitted to send them. Tim had met me only that day. I might be a fumble-fisted lid for all he knew. And he was busy with the press and with all the details of the ceremony. "We'll see...", he said. And that was enough for me. Now the final transmissions from WCC/WNU began. We copied them off the air. The room fell silent. I noticed one man in particular. He was probably the oldest person there but had a presence that we used to call "spry". He had a quick laugh and twinkling eye. I watched him now. He stood leaning forward, eyes closed, as the sound washed over him.... drinking in... the Morse. He was a pioneer operator, the genuine article, no doubt about it. I wanted to meet him, to ask his name at least. But of course I couldn't possibly interrupt his reverie. Paul Zell sent the first of the KFS/KPH sign off messages from the local position. Again we were all silent and when he finished... there was a round of applause! Applause for a radiotelegraph operator! Well deserved applause, deserved by every radiotelegraph operator everywhere, applause unheard for 80 years. Paul made a small, embarrassed nod of his head, accepting the tribute for himself and for all the operators on all the ships and at all the coast stations over the years. Then he copied the last commercial message KFS would receive, from the Liberty ship Jeremiah O'Brien/KXCH on 500kc. The op on the O'Brien said he would standby until 15 past the hour. Zell replied "better make that 18 past, OM." The operator on the O'Brien understood and said that yes, he would observe the silent period - which of course is no longer required by regulation but is absolutely required by tradition. Then Paul said that he'd standby "on 600". The crowd got a big kick out of that - 600 meters instead of 500kc. Subtle, but all the more meaningful for that. I saw Tim approaching me across the room. "Get your key...", he said. Get your key! Holy mackerel, they were going to let me do it! So I got out the key, gathered up my messages, and plugged in. But then I realized: the best Morse operators in the country... the best Morse operators in the world, probably... would be listening to every dot and dash I sent! They would be too polite to say anything if I flubbed it of course... but they and I and everyone else in the room and all the ships at sea would know! My palms started to sweat at that thought but there was no turning back now. I took Paul Zell's seat. I sent a couple if Vs to see if there was side tone in the 'phones. The knob on the key was loose! I tightened that up... and began to send. I sent the first message from the Maritime Radio Historical Society and all went well. Then I signed the station calls.. "de KPH/KFS". Tom and a few others noticed that I sent KPH first and understood why. Then the second message from the San Francisco Maritime Historical Park. And the calls again... followed by my "sine"... and K. I had gotten through it! And there was a round of applause for me! Thoroughly undeserved but very much appreciated. Someone even said, "Nice fist". High praise indeed in that crowd. Then the final messages from KFS/KPH began. Paul Zell sent the first ones. Then Tim Gorman sat down and proved himself to be much more than just a competent manager. He sent the final message in meticulous Morse using the chrome-plated Vibroplex, signed off with "What hath God wrought"... then SK... and it was over. There were wet eyes in that room, mine among them. I heard more than one tough-looking old timer mumble, "I didn't think it would get to me, but..." and then turn away. I had one further item on my agenda: to get my license endorsed showing me as an operator at KFS/KPH on the last day of North American Morse. Once again Tim Gorman showed himself to be a gracious and understanding man as he took pen in hand to write "satisfactory" in the blank provided for operator evaluation on the back of the license and add his signature. Finally it was time to go. I gathered up my key and my photos and my papers and shook hands once more with all the great men and women who were there. And finally we were heading north on highway 1 with the beautiful Pacific sunset on our left and the green coastal hills on the right. "That was one helluva day," Tom said. "Yep," I agreed.

I left the US Navy 20 years ago as a ballistic missile submarine officer. A program had been started on board just as I was leaving to upgrade the CW capability of the radiomen, who up to that time never used CW and most of whom could not do 5 wpm. It seems that someone, at what level I never found out, had decided that if the missile boats ever had to perform their function, it was unlikely that most of the exotic communications systems, including satellites and land-based VLF stations, would be in service afterwards. Thus, maybe the old standby of HF CW might be useful. On my boat, an engineering officer was given the collateral duty of providing the CW instruction, since he was a ham with better CW proficiency than any of the radiomen or other officers on board at the time. I think they practised copying the NAVAREA and HYDROLANT broadcasts from NAM/NMG/etc. on 8080 kHz. Apparently this program was not universal, as I have spoken with radiomen on active duty elsewhere in the Navy at the time who report no such additional emphasis being placed on CW by their commands. It sure did seem to make sense to me then, and still does now. Regards and 73, Mike / KK5F PS: I never did use my 2nd Telegraph license, but I still fondly remember copying WCC news/sports/stock bulletins every evening to get ready to take the exam. (But the exam's random code groups almost killed me!)

That is why they have/had multiple bands/calling/working frequencies. Pick whichever one was the strongest to move the traffic. The shore stations monitored many bands and scanned calling frequencies in each band listening for someone calling them, then came back at them and moved to whichever frequency worked best. The modern freqency hoppers would be doing effectively the same thing in an automaton mode by packet rather than morse. Packetizing it would reduce the size of units (we might call them morse letters), and allow transmission in bulk with requests for fills at the end, or singly until received, or broadcast ratcheting across all bands sequentially or en masse, or something like that...... There is probably a whole potful of scenarios you could imagine that could be used. I am curious as to why the military would use those kinds of schemes for images, which could be quite large, where VHF or UHF satcoms might be faster or less hassle. Were they wanting to use it as an encryption method by increasing the numbers of channels to catch all possible packets? The more frequency agile the system was, the less interception of packets for reassembly by the enemy. Also, the more complex it becomes, which could introduce many unexpected problems. Interesting. The Enigma Channel Hopper Scheme.... ECHS encoding.... Nah..... CW is more fun.

I left the US Navy 20 years ago as a ballistic missile submarine officer. A program had been started on board just as I was leaving to upgrade the CW capability of the radiomen, who up to that time never used CW and most of whom could not do 5 wpm. It seems that someone, at what level I never found out, had decided that if the missile boats ever had to perform their function, it was unlikely that most of the exotic communications systems, including satellites and land-based VLF stations, would be in service afterwards. Thus, maybe the old standby of HF CW might be useful. On my boat, an engineering officer was given the collateral duty of providing the CW instruction, since he was a ham with better CW proficiency than any of the radiomen or other officers on board at the time. I think they practised copying the NAVAREA and HYDROLANT broadcasts from NAM/NMG/etc. on 8080 kHz. Apparently this program was not universal, as I have spoken with radiomen on active duty elsewhere in the Navy at the time who report no such additional emphasis being placed on CW by their commands. It sure did seem to make sense to me then, and still does now. Regards and 73, Mike / KK5F PS: I never did use my 2nd Telegraph license, but I still fondly remember copying WCC news/sports/stock bulletins every evening to get ready to take the exam. (But the exam's random code groups almost killed me!) >> Greetings I also had the pleasure of serving Uncle Sam on a fast attack on the west coast & on a fleet ballistic missile sub on the east coast. This was in the early '80's & it seemed that more emphasis on learning CW was placed on the missile sub. The Navy had practically given up stressing the use of CW before I enlisted. The old time radiomen were quite proficient but the new men coming out of Radio school were never taught CW. Only a few new radiomen were trained in CW in Radio school. There was one missile tech onboard who was an Advanced class ham who the CO allowed into the radio room so that he could help the other radiomen copy CW during radio drills. He & I got blisters from rapidly changing frequencies on our R-1051B's. We both loved CW but the other non-ham radiomen were convinced we had some loose screws. Perhaps they were right. The reason we were given for the increased emphasis on learning CW was because it was very easy to disrupt communications with EMP, jamming & a carefully aimed shotgun blast from an enemy satellite to one of our NavSats. The thought being that if any thing can be copied through that mess would be CW by a trained operator using the best filter ever devised: the human brain. Being a ham & a radioman who could copy CW faster than 5 wpm I was given the order to train the other radiomen on board with daily CW practice. I had a blast. The command provided me with a Bencher paddle & an iambic keyer. After a few days of practice of sending random 5 letter code groups the men got bored. In order to pique thier interest I started sending selected passages from various Adult publications I had previously snuck aboard. Needless to say thier boredom disappeared & they were able to get thier code speed up to about 15wpm. The submarine group that my boat was attached to also had monthly offcrew CW testing sessions. The object was to copy 5 letter code groups at 20 wpm with no errors. The award for such a feat was known as the "Gold Key". It was a coveted prize among all submarine radiomen. It was a standard Japanese golden colored staight key mounted on a wooden plaque with your name, rate, date of solid copy & command. My "Gold Key" was presented by the Admiral himself & I still have it displayed next to my DXCC, WAC & WAS. Toward the end of my enlistment, CW was still being stressed as a desirable attribute of a submarine radioman. I just hope CW is still considered that by the submarine community. Diesel Boats forever & CW forever! Roman Dementiuk, N2CDD ex: RM2(ss) (I made RM2 twice - but thats another story.)

In the shortwave spectrum, noise and path loss not only vary with frequency but also vary with time in ways that are not predictable except in a general sort of way. And, one does not know how successfully a transmission has been made until after it has occurred. Therefore, it is not so easy to "characterize" a given transmission path as it is in the case of transmission along a twisted pair, a modern modems do, since the characteristics of a given propogation path from moment to moment, on a given shortwave frequency vary in short term unpredictable ways, due to fading and rapid fluctuations in the reflective medium ( the ionosphere) and transmission attenuation in the atmosphere due to turbulence and other factors. The packet system only works because a given packet can be re-transmitted until it is assumed to have been received correctly. If the number of packets being sent is relatively small, and the packets are relative simple (small),this re-transmission process is acceptable and requires a relatively small additional amount of time. However, if the number of packets becomes very large, and the individual packets become more complex, re-transmission times become much more significant, even to the point of throttling the datra rate to such an extent that the process basically fails - the needed data rate cannot be obtained. Another factor is noise. One can never get rid of noise. The only thing that can be done is to obtain and maintain an exceptable signal to noise ration. In the presence of the combined affect of atmospheric, stellar, man made, antenna/transmission line and receiver noise, variations of the signal strength can have a profound affect on the quality of data arriving at the receiving end. To date no one has ever completely eliminated the affects of noise on data and methodologies which "process" the data to reduce the affects of noise require more time., which must be added to the time required to send additional packets to ascertain the data got through. It is not possible to "process" a signal, from which data is missing are retrieve the missing data. The best that one can hope to to is to attempt to "characterize" the missing data, making assumptions about what it might have been and replacing the missing data with this assumed data, which actually becomes analogous to the inclusion of artificial circuit/signal noise. This also takes time. There would be some advantage to sending the same packet of a variety of channels and then combining the data streams at the receiving end so that bits missing from one stream would be added by another stream which had not lost that bit. But, now we are tying up gobs of spectrum to get the required data quality, defeating the original purpose - unless the demand of the system for spectrum is not a criteria and sufficient spectrum is available. The great race to the higher frequencies has resulted from the fact that any problems associated with propogation diminish almost proportionally to the increase in complexity of the radio/antenna part of the problem, but system vagueries are more predictable and controllable than propogation vagueries. So, the idea of using HF to send images would automatically work better at higher frequencies - all other things being equal. It is probably true, that barring low achieveable data rates, the human operator can make better use of the shortwave spectrum than a machine, unless very large antennas and great transmitter power are available. Even then, it boggles the mind to think of writing software that would run in a computer, adequate to the task of sorting out all the vagueries that a good morse operator deals with routinely in the accomplishment of his/her work. But, we have netered into a new age - one in which the human operator has become the imagined villian of higher states of productivity and product quality. Even a cursory look at the history of the "Industrial Revolution," will reveal that the owners of business have been trying to rid themselves of "manpower" ever since the water wheel was invented as a source of power. All the improvements in machine design and automation has been with the expressed purpose or reducing man power requirements. Now, the goal is to eliminate manpower requirements, as machines increasingly demonstrate their ability to preform simple tasks which can be structured in such a way that all vagueries have been eliminated or reduced to inconsequential levels which are acceptable in terms of final product. Every area of modern eandeavor is being impacted by thisd attack on human involvement is product production processes and it doesn't seem to matter what the process is. The FAA, as an example has been studying automatic landing systems for years to get rid of the need to have a pilot in the airplane. Right now, unmanned vehicles are plying a large oval track South East of Carson City, Nevada, for the expressed purpose of developing unmanned over the road trucking and transportation. The car of the future will drive itself, using GPS to get you from door to door. Computers and robotics are beginning to invade the operating room and doctors are no longer allowed to prescribe drugs and treatments in Emergency - patient data is fed into a computer and the computer makes a diagnosis and prescribes the treatment - the insurance underwriters are pushing for this, because apparently people make too many mistakes! We live in a dollar driven world. The dollar is the only thing that counts. Virtually everything in our culture gets pushed through the "dollar" filter and either makes it through or doesn't. Human values seem to play a very small role in modern commercial thinking. When I was a young engineer, companies had "personnel department." Now, they have "Human Resources" departments. I looked up the word "resource" in the dictionary and found that it means, "something exploited for profit." That is the best indicator of the "modern" attitude of business people to everybody else - something to be exploited for profit. And, when a better resource comes along which is easier to exploit for profit, the human "resource" is cast aside. There is nothing new in this process...it has been going on for ten thousand, only in those days, the weak slave was killed so that the strong slave could be fed. Simple mathematics. Today, we are just a little more compassionate about that - we let out weak slaves waunder around the street, living under card board boxes. It's not nice to kill them, you see - it erodes the opinion other people have of us. For many people, land and water and shinning mountains are just real estate. The Sky is just another form of real estate. Wind and radio waves are just real estate. The Sea is real estate - something to be controlled, consumed, bought, sold, fought over and then, like everything else, thrown away - just like we do toilet paper and dixi cups. Now, people have decided that the Shortwave bands are more trouble than they are worth - just as they did vacuum tubes, steam , sails and telegraph operators. So, what else is new. -- Conrad, W7WLM Brad Hernlem wrote: > John W7ZFB writes: > >Before I'm gone I expect to see hams using most of HF... > >Who else would want such a noisy, unpredictable place? > > The New Scientist magazine carried a story a week or so ago about a project > by the military to use HF for transmission of images.

We all like the CW, and I guess I am one of the biggie basketcases with it (but hey, I do the latest internet/unix/web/etc stuf all day, so it is refreshing to use CW and GB and BA to get the head back on straight). Enterprise is strictly to blame in the case of shipboard CW. When the USCG dropped MF and HF CW, it was strictly a bottom line bean counter thing, and not at all related to the new technologies. I have that directly from the fellow in charge of making those decisions, back then (1992). Alas, I can't find those emails anymore, so my word will have to be taken with a couple of grains of sea salt. As to the commercial marine CW traffic, that too, was a bean counter thing, where replacing a 100K a year crew member with a one-time 50K investment in gear, was the way to go, by the ship owners. For routine traffic, that is not necessarily a bad thing, but for emergency traffic, it has lost the human touch, and we have yet to see how well that really works, under fire. My best guess is that it will take about 10 years for the dust to settle in the system, before all the bugs are out. > As for the almighty dollar, wake up and smell the roses.

Hey, I luv that open software. It makes it possible to live with and around the NT toyz around here. I tend to be a BSD freak, but that is my bent. Interestingly, it is the internet, that has opened up marine telecoms to the point where it is becoming an email operation.

In order to practice, dilligently, the art and craft of the Brass Pounder or CWist, on the air, and with like minded stations, I propose we meet each Friday evening QTR 0300Z QRG 7147 KCS for an informal roundtable and friendly discussion. Call will be CQ BP CQ BP DE K. The reason for 7147 is to allow those with lesser skill to join in and for the novices to hear us and maybe tag along to ratchet up their skills. We need to try to mentor all hands along. In winter, if it stays going, we can try an 80M novice QRG. If you have a straight sending iron, use it. If you have a bug, use it, but slow it down if appropriate. If you have an automatic key, use it, but slow it down if appropriate. If you have a keyboard, use it, but slow it down if appropriate. The point is to put it to use with your CW skills. If you have Glowbug gear, use it. If you have BoatAnchor gear, use it. If you have modern gear, us it. The point is to put it to use with your CW skills. QRQ will be appropriate for the slowest operator. Some short traffic/info may be appropriate. Short discussions of CW, radio history, Glowbugging, or BoatAnchoring are appropriate. Short discussions of operating practices and skills are appropriate.

Back when I first thought seriously of going out to sea, in the late 70's, the base was 20K and you effectively got as much overtime as you could work so the total was 30-40K. After Desert Storm, the base, from what my friends told me, was double that plus, so 100K was reasonable, with union contract vessels. Alas, the ROU has apparently filed for Chapter 11, and the era is over..... Anyone have the web site for the ARA or ROU or MEBA? I wonder if my buddy (ROU) who did go out from 1977 on, has a job or retirement, now..... I always have wondered what would have happened had I gone out starting in 1977, or earlier.

Yeah, we wuz born too late. > Old dreams and all..... oh, well, we do it ham style, now.... I thought seriously of doing that back in the late '60s and early '70s. I worked like heck to get my code speed up above 30 WPM by copying the Navy VLF stations on my RAK-7 and simultaneously taught myself to type on an old Remington portable my cousin gave me. The Navy had not yet changed completely over to TTY at that point and was till sending 5 letter code groups at a pretty fast clip. Sure got my code speed up in a hurry. I also was NTS laison from RN7 to PAN and eventually became TCC. I was a Conditional Class licensee then. I got an interim job with a local TV station and had to have a 1st Class 'Phone, so one day I went over to the FCC office in Seattle, which was about 400 miles from Missoula, Montana where I was living, and spent the whole day taking tests: General, Advanced and Extra, 1st Class 'Phone and 2nd Class Telegraph. I went in there at about 8:00 AM and walked out at 5:00 PM with a splitting headache...and passed all tests and got all three licenses. I then tried to get in the ROU, but, due to my poor eyesight, had difficulty getting past the Coast Guard requirements. I am legally blind without my glasses. The ROU even had a ship lined up for me...drat! I wanted to travel. The pay was excellent, and if one stayed out of the country for 18 months or longer, one didn't have to pay income taxes on what one brought back in. Perfect job for a single man. Instead, I ended up staying in Missoula, working first for radio and TV stations, then the University of Montana. I sure wish I had been able to go to sea instead.... Oh, well. Man proposes...God disposes.

Well, we all were a little gunshy at first dit..... For heavens sake, this kid froze up solid into a block of mushy ice on my first reply to my first CQ. It so blew me away I totally lost it. My second CQ came back with a kind Canadian ham (DX no less!) in the upper reaches of Quebec that came back to me on voice (15M)! I am sure he understood my total fright, showing through on the key. I still have that QSL up on the shack wall. After the first nukem attempt at a QSO, it kindof made my day. Then, with the palms still sweaty, I sent out a 3rd CQ, and the rest is history..... I do think, now on the other end of the voyage, that it is a good idea to mentor the newer hands, on the air, if possible, because it is a totally different experience, there, compared to the Instructograph tapes, cassettes, or computer programs. Also, there is a lot of the operating skill/proficiency end of the art and craft that is best demonstrated. We learn a little, about it every day, or every QSO under our belt. My net skills are a tad rusty, although I used to pass a fair amount of mars traffic on CW, about 20 years back. But, now is the time to polish up all those kinds of things, now that we, as the amateur radio service, are ``the last stand for brass pounders.'' (By the way, can anyone tell me where that phrase comes from?.... more later on it). > Vis-a-vis traffic, that reminded me that within 24HRS of my call going up on > QRZ, I got a Radiogram from a ham in MS or AL.

Anyone still handle CW > traffic, including Radiograms? Tfc is handled every day, although it is mostly net reports and that kind of thing. There is some msg tfc that comes in on holidays and the like. Although, I did not intend to start a real net, it would be good to occasionally pass some tfc, just to keep the fingers honed, and introduce the new folks into the practice. Even us olden pfartes need the practice, now and then.... All hands.... how many folks aboard are regular tfc handlers? occasional past Mebbie we can coordinate some training examples for the group, or such?

Hope to see you there..... ZUT DE NA4G/Bob UP (p.s. the reference to ``The Last Stand for Brass Pounders'', comes from the title of an article on shipboard radio operating in the Merchant Marine, published in one of the popular electronics rags of the time (PE or Popular Mechanics, or Modern Electronics or something like that) from about 1965 or so. That article always fired up my radio imagination, most heartily. If anyone finds the citation to that sometime, do holler! I would like to find a reprint of it. TNX/NA4G/Bob.)

Mostly CW, but also 'phone and RTTY. Several times, the Montana Section Manager tried to see if he could overload NTS during the annual SET. I did the first one totally CW and handled LOTS of traffic. By the next year, I had the RTTY set up and I we didn't have much trouble handling his load. I don't exactly remember the number, but it was around 500 pieces over the 24 hours. I even had an 80-to-20 meter RTTY repeater set up which worked surprisingly well. I used a TTL2 for the receiving converter, connected to a BC-779 to which I had added a triode product detector, and a modified VF-1/DX-35/BC-610 for the transmitter. Had a complete model 15, 14 typing reperf, 19, and a tape sender setup. My mother didn't like the noise much, but I really enjoyed the rythmic clack-clack-clack. Thank heavens I was in the basement! The BC-779 was interesting: I could hear the signals on 20 drifting slightly back and forth. Didn't seem to bother the TTL2 enough to prevent copy though. But, boy, was that '779 sensitive with its two RF amp stages and the product detector! And SO quiet! It was a real pleasure to use. I used 1/2 of the 6N7 noise-limiter tube for the product detector. You can probably tell that I am getting to be an Olden Pharte, what with all the reminiscing...

How about a 6146 (with all the screens tied together)? I just happen to have one that's asking to be used for something. What value should R1 be changed to? I'd like to change the lightbulb output indicator to an RF ammeter. What's the highest antenna current you'd expect to see?

Hmmmm. How does this sound re. the amount of RF amps coming out of the 6146: assume it puts out 50-watts into a 50-ohm load, like a matched antenna---the formula P = I (squared) x R would translate to power equals current (squared) times resistive load (antenna impedance). To secure current alone, power would have to be divided by resistance, and then the square root of that would have to be taken. In our 6146 example, power (50-watts) divided by resisive load (50-ohms) equals one, the square root of which is one...thusly, one might expect one ampere of RF current delivered to the load...

Oh, he would take a tributary toke on a cheap cigar to commemorate a new baby, but he never took up smoking despite being from an age when it was considered a badge of manliness. I saw the end of that age and succumbed for a while. But my pal who plans to take back 56-60 mc with a Five Meter Liberation Army knew a simple truth. The differential diagnosis between males and men was made in bar ditches like this one, with the sun making little apparititions on the macadam, the bugs regrouping, and time moving more slowly, but more more completely, than it ever does indoors where they sell Camels. He took some of it for himself and handed me the package of Bull of the Woods. It was an ancient but still moist sample. I could tell because the bull was still just that, not a steer like he, or it, is now. Frank has a lot of old fashioned things. I took some tobacco and put it in my cheek. We men, if we, or I, qualify, have silent rituals and this was one of them. It was one of the easier ones, too. You could tell what it asked and know what to do about it. The real tests come on you so fast you don't have time to prepare --except for all of your life up to that moment. Frank was well prepared. I could see the stock was plain hardwood without any fancy spacers or little porches for a fellow to lay his cheek while he squints thru some little telescope. Frank told me once he enjoyed bullfights. I thought that strange then, but today, at the entrance of a ramp off I-20 in the afternoon, I understood why. No one would applaud if the Matador took out the bull from the stands -- he has to face it. It was a Drilling, the way Europeans say it, but we, in our feigned Proletarian parlance call it an "over and under." The bottom, the bigger one, had to be from the '60s because no one makes them that way anymore. It was for the 2.4 S Band and it was adorned in the old way with an animal, a totem I suppose, along with the legend "Bear Buster." Above it sat the modern one. It did X at 10.5; K at 24 and, in the bargain, the Ku at 33 Gc. It said, "Sharpshooter," and another animal, a Cobra, coiled on it. Those devices were like Frank's old super-regenerative receivers in that they put out as much signal as they "detected." They were wired together to a single trigger and a line ran from there to a chest crossing bandoleer of D cells that made Frank, in his bush jacket, look like a comically miscast Pancho Villa. The D cells said simply "Ray-O-Vac," but I noticed Frank's shoe sole had a cat on it and the handy talkie he answered now bore ducks -- several yellow ones and the legend "Sleepy Time Sentinel." "I need at least 5 points," he told the WARmon, which is what I call his assistant, on the recrystaled baby monitor. We looked over the trench edge and a three pointer roared by. It started up the long, banked incline past us with it's Bug Catcher leaning back in the wind. I could not make out the other two antennas, and Frank just spat some of the 'Bull and said, "an appliance operator, yeah, but not an old one." It seemed we had been there forever, but then it all happened quickly. The WARmon called out a 6 pointer and, to Frank's question, replied, "no tailgaters." We waited. I could not have done it alone. I thought he decided, for some reason, not to do it but, at the last minute, he sprung up and, always the follower, I did too. It was a Land Rover, and he told me later he was glad as they are one of the simple, useful things that are now "so feminized as to be perfect fits in a woman's world, but useless in a man's." He watched it. I guessed he might be counting the antennas and calculating the store-bought appliance each represented. He did not say. Not then. Not later. He had the weapon at his side and in the near-frozen time I noticed it said "Law Enforcement Wideband Impulse Simulator" in Duco letters on its butt plate. He never raised it. He fired from the hip and stood his ground. You never know what they will do when you hit them. It might have come right at us when the hash from 8 thru 30-something Ghz radiation hit its bank of detectors. Frank had eye contact, of course, but he lost it as the guy, a fat guy who looked somehow familiar, turned to look over his shoulder and, at the same time, sat on the brakes. The Rover passed us so close I could smell the stench of the tires. But it did not really make the bridge. It sideswiped the left side, then the right, and finally righted itself. But a huge, center-loaded whip sheered off and fell to the old, dry creek bed below. I looked at Frank to see if we should go after it. "I'm not a trophy hunter," he said, "Let's go." We moved quickly then, or as fast as we could go with my various infirmities, but Fate missed me that day and took Frank. His Navy last Brogan slipped into a hole, spat and all. He fell and by the time I helped him get it out of the indention, he was already swelling. He regarded it cooly, like it was something, or someone, else despite what must have been significant and growing pain. "I can't go on," he said, "Leave me the LEWIS gun and go on without me." As the WARmon, (who is an ex-Boy Scout if that is possible), and I lifted Frank onto a stretcher made from sheer-away road sign posts and the seat cover from the Frazer, I said, "The Spanish Civil War was over 60 years ago, Frank." "Maybe so," he answered. I saw he was not looking at me, or his ankle, but at the setting sun. "But tomorrow," he counseled, "when you wake at first light and hear the birds, remember that every day is a new war."
