While perusing the July 1938 issue of Radio News this weekend, I came across an article with a design for a nice 6L6 MOPA 160M xmitter with choke-coupled plate modulation. The article includes coil winding info. The tube lineup is (3) 6L6, (1) 6F5, (1) 6C5, and (1) 83. I'll gladly send a photocopy to anyone who sends a SASE (32 cents should do it). P.S. Thanks to Mike, KK6GM for the reminder that this is the 60th anniversaary of the 6L6 and the 807. P.P.S. Post me at the Westminster address. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % % Michael A.

It was a Millen 90800 (I think that was the number). ARRL handbook back in late thirties had the design for it and MILLEN appears to have copied the ARRL design exactly (even the mechanical details). I had a full set of coils for it. Open construction. This was long before TV came to my area. Even got a QSL from the FCC one time when I made the mistake of using a crystal whose 2nd/3rd harmonic was outside the next higher band (learned to always calculate harmonic frequencies after that - heh heh! - Oh, and tune carefully, too...)

Date: Sunday, February 04, 1996 1:07PM Many think this R-390A/URR is the best all-around receiver ever made. This one is a late model (one of the last production runs), made by EAC. It is big, heavy, uses tubes. Quality look, feel, and performance. 110 or 220 VAC. Even has ovens for oscillator stability. Upper tuning limit 31.999 MHz Has 6 IF selectivity filters ( 0.1, 1, 2, 4, 8 and 16 KHz). Also 2 audio filter positions (Wide and Narrow). 2 meters (Line Level, Carrier Level). Total of 17 knobs (Line Meter sw, Line Gain ctl, Ant Trim ctl, AGC sw, Limiter ctl, Audio Response sw, Break-In sw, Bandwidth sw, BFO Pitch ctl, Function sw, BFO sw, Dial Lock ctl, Zero Adj ctl, Local Gain ctl, RF Gain ctl, Megacycle Change ctl, Kilocycle Change ctl) Rack mount style (no cabinet, but has all covers). 19 in wide, 10.5 high, about 15 deep.

I thought that I saw somewhere that they were still available [surprise]. Anybody got any ideas Thanks, KIM ------------------------------ End of GLOWBUGS Digest 97 *************************
