[Milsurplus] RE: Milsurplus Digest, Vol 8, Issue 1

Fri Dec 3 09:10:34 EST 2004

Good Morning,

I am mostly interested in Spy Radios, WW2 Submaine Radio Rooms, etc. However, my employer maintains a small archive of "Company News Letters", etc., dating back to 1946.  We aquired other companies (Emerson Radio, and part of North American Philips) in the early 50's in the Boston area. Sylviania (and other famous names we have D.B.A.) built the RS-6, TRC-77, PRC-71, PRC-63, PRC-90, ARC-113,114,115, and others. We also have copies if articles from the Sylvania Technologist (tube and sub-minitaure tube development in example)from the 1950's. I don't have access to technical manuals, drawings, etc. I don't think they exsist anymore in house. I do know that the news letters contain information about product development, contract awards and so on. The last time we built these types of products was 30 years ago... If anyone is looking for historical information for these systems let my know, and I will see if we have anything for your area of interest. 

73,
John KB1KRN

Nameplate should be on top of the cover. The coil unit you posted the number of plugs into the right side. On the transmitter nameplate, it will say something like "A Unit of Model GF-??...". I have manuals on a few of the GF and GF/RU models. Aircraft Radio Corporation (CBY) built the earlier models. Western Electric (CW) built the later ones, or at least some of them. I'm far from an expert on the GF/RU (or the Signal Corps versions SCR-183 and SCR-283) but these are/were all also called Command Sets. A set consists of transmitter, receiver, stack of plug-in coils, junction box, common dynamotor and miscellaneous accessories and connectors. Came in 14 volt and 28 volt variants.

The crystal was cut for 200 kc and came in two types. DC-12 apparently came first and plugs directly into the 5 pin socked provided. After serial No Dennis D.

After serial No. 17,691, the DC-24 in a FT-241-A case was used (mostly). The 5-pin to octal adaptor 2Z262 was required when this later crystal was used. Info from TM 11-275, 24 January 1944.

Sponsored by the Collins Collectors Association. Cedar Rapids, Iowa - Wednesday December 1st on 3880 kcs at 7:30PM local East Coast time marks the start of the latest chapter of First Wednesday AM Night, drawing hundreds of vintage stations from across the country. The event is anchored by a "tall ship" AM station in each time zone. The East Coast will run for 90 minutes in response to the tremendous participation in the Eastern Time zone. The remaining time zones will be an hour. We encourage stations to check-in on AM using Collins and other transmitters, new and old. It's an opportunity to revel in this nostalgic mode, enjoy giving vintage equipment a "run," and sharing some storytelling about classic vacuum tube homebrew and commercial designs. Typically more than a hundred stations take part in the evening's coast-to-coast AM event; by the time it concludes at 10P, PDT (1A EDT). A logbook of check-ins, with the equipment used, appears in the "Announcements & Events" section of www.amfone.net on the page's "AM Forum - BBS." In months past, anchor stations have included those running the beautiful Collins 300-G, pictured below, as well as those running the amateur KW-1, and other noted models. http://www.amwindow.org/pix/jpg/300g.jpg LISTEN for the following anchors and stop by to say hello, won't you? You don't have to be running Collins or vintage gear to be welcomed into the group. 7:30P-9P East Coast Anchor: Bob W0YVA 8P-9P Central Anchor: Jim W0NKL 8P-9P Rocky Mountain Anchor: Jim WA0LSB 8P-9P West Coast Anchor: Bill N6PY comments please to wa9vrh at mtco.com ------------------------------ Message: 11 Date: Thu, 2 Dec 2004 15:54:30 -0800 (PST) From: michael tyler <michaeltylerwv at yahoo.com> Subject: [Milsurplus] sem-52a wanted To: milsurplus at mailman.qth.net Message-ID: <20041202235430.1810.qmail at web20325.mail.yahoo.com> Content-Type: text/plain; charset=us-ascii looking

Problem is ratings and model application. The parts lists in all of the manuals that I have on all three major groups (EMOPS, HKLR and JNQ) give 220 volts @ 70 MA as the dynamotor output rating. Some of the manuals have changes incorporated as late as 1954. But, I have two here with output ratings of 230 volts @ 100 MA. One is loose and I don't know for certain that it came off of a DM-28 base, although the tapped holes in the field housing are in the correct locations. The other is on a typical DM-28 base, and the condition of the components and wiring is grungy enough that it is probably if not original, at least older than most of the list members. The base is not for a JNQ as the B- goes to the terminal strip but does not go to ground, and the sheet aluminum cover is full length. Neither dynamotor proper has a DM-28 nameplate. Both do have the contractor dataplate indicating that they were made either for or by Bendix Radio. Does anyone know anything that would shed any light on the mystery? 73 Robert Downs - Houston <http://www.wa5cab.com> (Web Store) <wa5cab at cs.com> (Primary email) <wa5cab at houston.rr.com> (Backup email) ------------------------------ Message: 13 Date: Thu, 2 Dec 2004 20:11:07 EST From: W7QHO at aol.com Subject: [Milsurplus] Re: 3 Sig.

Of particular interest here because he processed into the Army at Ft. MacArthur down in San Pedro, CA, where I volunteer.
