[Milsurplus] Looking for info on WWII USN TX

[Roger Basford]

Hi,

Just joined the group. Excuse me taking up a lot of b/w with a first 
posting!

I have a piece of WWII USN equipment here that I have been unable to locate 
any info for, so it's time to ask the experts. The radio is a GWY-2A AM/MCW 
TX made by Doolittle Radio Inc of Chicago in 1944. It also has a plate on 
the top of the outer case reading "Radio Transmitter Navy Type GS-5, 
Contract No 3259, Procurement Directive 14008-44, serial No 15".

It is quite a distinctive looking rig, with four identical Triplett meters 
on the front panel. It's similar in size to a ARC series TX, maybe a little 
larger, and is designed as a part of a modular system to plug into a 
backplane. Inside it runs a 1625 final modulated by a pair of 6L6Gs with a 
set of Thoradson transformers. Looking at the tank circuit I'd guess it runs 
on a single frequency of about 7-12 Megs with a octal-based crystal 
operating at one-quarter carrier freq. One quirk is the use of the same type 
of coaxial connector for both antenna and microphone, but the type used is 
unfamiliar to me.

I bought the rig this summer at a UK hamfest and found absolutley zilch on 
the Net. I have discovered another mil collector locally (G4XWD) who has a 
GWY-2A but again no info. An advert in the UK Vintage & Military Amateur 
Radio Society newsletter produced a little more info, in that there were 
originally six of these rigs in the possession of a UK collector but they 
have been disposed of and he now has only one left, again no info. I have 
enquired through the Electric Radio listed manuals dealers but they were 
unable to help, Robert WA5CAB did post to this list but got no replies. I'm 
hoping ER will run a "wanted" ad for me this month.

So, anyone recognise this rig? It's in very good condition and I'd like to 
put it on the air. Photos available!
