[R-390] 390A contractors

[Les Locklear]

There are many PTO's with a Raytheon sticker on them. Raytheon didn't build PTO's that was a rebuild contract. There is a list out there that has contractors that were building modules on a spare parts contracts. Most of them were also the R-390XX manufacturers. Some weren't.

So in the subject of contractors, were there suppliers of just subchassis? I have been told that Teledyne, Amelco, and Imperial all worked together to build their radios. So we know of 5 contractors of PTOs- Collins, Cosmos, Motorola,Dubrow, and Progressitron. Perhaps others?
So my real question is were running spares made up separate? I know there were new IF strips made. I saw some at a hamfest. As always, fascinating info. 73s Russ.
