[Milsurplus] T-827 transmitter questions

[W2HX]

Ray, this is an interesting idea. One could conceivably compare the manual of the T-827 PA interface section to the PA interface section of the AM-3349 to see what similarities could be leveraged. Very interesting!

The AM-3349 may have possibilities, that’s the amplifier for the AN/GRC-106 and with +10Dbm or so drive will give 400 watts peak to peak. The GRC-106 uses the same rotating drum from of  tuned circuts as all that Navy junk like the R-1051, URC-35, WRC-1 and the T-827 exciter. Think that’s all part of a technology that General Dynamics had a lock on back then. Although I have no direct evidence to prove this would speculate that the command and control for selecting the appropriate band element on the AM-3349 may be closely related to the AM-3007.
I always wanted to play around with the URC-35 but they still sell for stupid money. Do know from a distance that the AM-3007 is supposed to be an issue with a PA tube that’s imposable to get and when it was working only good for 100 watts or so. The AM-3349 from the 106 is way cheaper to buy, at least at ham fest and the like have seen them for as little as $250.00 working and $100 broken and from my experience a more robust and dependable design. But that’s just my opinion and until I own a URC-35 it’s biased.

Hey all,

Question for those more intelligent than I in regards to radio design (ie, all here, lol).  Does anyone know of a homebrew amp, or a particular commercial amp that would work well with the T-827 exciter?  Granted, there's the AM-3924 (no chance of 3 phase power here though),  and then there's the AM-3007, but that requires 8223 and 8116 tubes.  Neither of those tubes are easy to get, with one damned near impossible from what I can tell.

Someone mentioned converting the 3007 to use more conventional tubes but that's (as of yet) above my ability without some help, so that leaves the original question.

As always, thanks in advance and 73
Reuben
