THE MIL LIST This is an ongoing project. Any and all are invited to contribute. If you have entries, PLEASE CHECK THE SUBMISSION GUIDELINES (appendix C). There have been numerous formatting headaches due to the various mail programs and the ASCII>WordPerfect>ASCII conversions involved in the editing. I'm also a detail freak. If you have little bits of info on equipment that is already listed, by all means speak up! I'd also appreciate feedback on the list. I don't know how it looks after it gets bitcrunched and packetted into a dozen different mail packages. My job situation is changing and I haven't had as much time to edit the Mil List. I want to keep the project going so I've relaxed my standards. I'll be more of a "melder" than an editor. In other words, the format and content of the entries on the list will vary depending on the contributor's style. I'd like to keep it relatively uniform, but my experience is that everyone sends entries in a unique style. From this issue on, I will no longer include entries received in non-left justified format. It simply takes too much time. PLEASE READ THE SUBMISSION GUIDELINES BEFORE SENDING ME ENTRIES. Thanks this time around to Tom Marcotte, A. Padgett Peterson and Jack Taylor. A special thanks to Jerry Proc.

The receiver was comprised of four wide band radio frequency amplifiers, one for each of the four antenna bearing angles. Each RF amp could be selected with a switch. Radar emissions from ships or aircraft would be received and displayed as blips on a small CRT mounted in the unit. These blips would also trigger an audible alarm whose volume level could be adjusted. There was only one drawback to the UPD501 - it could not be used if the ship's own radar was operating.

Thus contract 14214-PH-51 (an important Collins contract) was issued in Philadelphia in 1951. Equipment was often manufactured the same year (14214-PH-51 is a notable exception. See "Electric Radio", #27 for further information). ----------------------------------------------------------------- ----------------------------------------------------------------- APPENDIX C: Military equipment list volunteer guide: ---------------------------------------- Additions, corrections and suggestions are welcome. I am particularly interested in nailing down information on variants, like the differences between various BC-348s and BC-610s. Little details are as welcome as large blocks of new info. Everything helps. The Mil List will be available via the boatanchors archivesas long as it can be sent via e-mail. I will post a note on boatanchors whenever a significant revision has occurred. To keep this thing manageable, I'd like to limit it to radio related stuff, i.e. receivers, transceivers, transmitters, amplifiers and accessories (like converters, antennas, pan-adapters, couplers, filters...). Test equipment and other electronics may emerge later. E-mail is plain ascii text. You can type entries with any word processor program that can export plain ascii text. I use either Wordperfect or the DOS text editor than comes with v5.0 and later. I'd like entries to be as complete as possible, BUT every little bit helps. I'd like to keep the elements of the descriptions in somewhat similar order. If you can oblige, fine. If that's too much trouble, just type away and I'll try to keep up with the editing. Please submit your entries in the following format: (Note that submissions are in a different format than the guide. Everything starts in column 1 (left justified). It is easier for me to strip all the ASCII hard returns and edit the text if it is submitted in this form.)

I will assemble the list in alphanumeric order (that's why each description should start receiver, transmitter...). Each time I receive a submission from you, I will forward a current copy, with your additions included. If you don't submit entries for a while, be sure to request a copy before you start typing. I'd like to keep duplicate keystrokes to a minimum. It will take some time to build a decent list. With the work spread out among many hands, it will develop quicker and in greater depth. Thanks. ------------------------------------------------------------------- ------------------------------------------------------------------- Contributors: Tom Adams, Jim Beyer, Michael Crestohl, Bill Detschel, Bob Folwaczny, Dennis Gibbs, Emil Kasprzyk, Takashi Maeba, Don Merz, Tom Marcotte, Terry O'Laughlin, A.
