Navy R-4D aircraft of the period that I have seen restored or museum had ARC-1 and ARC--8 setups. Just a thought. Also, the MIL common VHF frequency was 126.18. Hence all those CR-18 (?) crystals we used to see.

Exploring putting together a USAAF SCR-274 set for a USAAF C-47 based here in NY ( yes, the C-47 was equipped with the SCR-274-N ). Here’s the rub. We need at least 1 VHF set pair ( transmitter & receiver) for the aircraft to talk to ATC if they want to use the 80 year old comms to do anything useful in the aircraft. Now I know that the USN ARC-5 had such a set up available, but the C-47 won’t be set up for the USN ARC-5 system, and the the transmitters for the two systems are not compatible with one another. Did the SCR-274 have a VHF transmitter/receiver set. If so, what is the nomenclature of the transmitter and receiver? Gives me something to start looking for.
