[Milsurplus] Fw: [RCA] SRR-13 conversion to SSB

[John Vendely]

Howdy,

Regarding your question about other military radio AM to SSB 
conversions, two others come to mind.  There was the conversion of the 
AN/GRC-26D RATT van to the SSB (and frequency synthesis) AN/GRC-129, and 
the conversion of the AN/FRT-24 to the SSB (and frequency synthesis) 
AN/FRT-24A.  Both were done by Manson Laboratories.

I have an AN/GRC-129, but am sorry to say I've never heard of anyone 
with an AN/FRT-24A.  Does anyone know of one still in existence?

73,

John K9WT
