The ARC-4 was based on a commercial rig developed by Western Electric before the war. They had a journal called "The Oscillator", and one issue had an article about their work on VHF aircraft radio entitled "Aviation clears it's Voice" if I recall right. I will look to see if I still have the journal.

10uV input for 50mW audio output doesn't seem all that bad for a receiver with no RF amplification. Was this a civilian aviation VHF transceiver drafted into the military early in WW2? I seem to remember that the ARC-4 was in service before either the ARC-1 or ARC-3, but you know how memory can confuse things!Jim

______________________________________________________________Hi,
I am an ARC-4/WE 233 person in recovery.
I pursued it because they were installed on USS Massachusetts, and because they work on the 2m Amateur band.
I used to take mine around to shows and talk between it and my ARC-1.
Read the description of the exercise K4CHE and I did, which revealed the relative deafness of the ARC-4.
