[ARC5] [Milsurplus] Interesting ARC-3

[WA5CAB at cs.com]

In 1967/68, VHF AM capability aboard USS Valley Forge and at least two 
other Gators in the squadron consisted of a single RCK and TDQ pair.  I don't 
know about the other four but the Valley Forge pair were installed in 1946 
when the ship was commissioned.  I and ETCS Ring may have been the only people 
aboard who knew where they were and what they were.
