I may have a chance to acquire an ARC-2 in half decent shape along with power supply. Does anyone have any experience with these transmitters? I guess it is both a transmitter and receiver in one box?

Great radio, was used a lot by the Navy back in the old days. Produced right after WW2 and replaced by the ARC-38 that was a fully automatic radio.
Biggest issue will be the rack and the connector for the back of the radio, I know I have never seen one and know at least one person who had to fabricate it from scratch. Also the receiver is somewhat broad. I think they built the receiver with a broad IF because frequency tolerances and control was not that good back in the old days and maybe they felt wide IF was better to account for everyone not being right on channel but thatís just pure speculation on my part.
Do you have the internal dynamotor?

I believe Mike Murphy WU2D was running one mobile for quite awhile.

I  was fortunate enough in my younger days to know some of the OTs who were AAF radio ops; mostly aircraft ops.  In addition to the noted reasons, which somewhat agree with their comments, they said that it was not always easy to tune a receiver exactly if you had to change freqs for some reason due to such things as turbulence, cold and the clothing required to combat it, and flak.  Xtal control of the transmitters apparently was more common than the receivers, but I fail to understand why.
