[R-390] Matching transmitter?

[Nick England]

The R-390/URR and 390/URRA were general purpose HF receivers. Military
installations sometimes had transmitters located 20 miles from the
receivers to avoid interference. (the 40kw AN/FRT-40 was a medium size
transmitter)
Shipboard the R-390A's and other receivers were in one compartment
(radio central) and transmitters were in another. The transmitters
could be anything from 1930's CW rigs (TBK, TBL) to 1950's AM/FSK rigs
(AN/SRT-14) to 1960's synthesized 1kw SSB xmtrs for RTTY (AN/WRT-2).
And an intercept site would have a hundred receivers and no transmitters at all.
So there was no really such concept as a "matching" transmitter.

HOWEVER, the standard AN/GRC-26D communications shelter was more like
a ham shack - receivers, transmitter, and RTTY gear. Consisted of two
R-390's and a T-368. This combo was probably relicated for many small
comm sites. The T-368 is thus an excellent "matching transmitter"
choice.

Now if you mean matching as in "made by Collins, looks somewhat like
an R-390(), PTO controlled, etc." then there was an oddball prototype
SSB exciter that used an R-390 as part of the freq synthesizer.
T-???/URT George Rancourt wrote an article in Electric Radio about it
- I think only one example is in existence.

DISCLAIMER - I've probably overlooked something completely obvious and
my only excuse is that the New Year's party ended at 0230 this AM and
I did my part to make sure there wasn't any leftover champagne.....
