[ARC5] British WWII Avionics

[Geoff]

When I was stationed at NAS Olathe KS 1959-61 the trainers used ARC-5's on 
HF, ARC-28 on VHF and ARC-27 on UHF. I used to see them regularly in the AT 
shop.

This was a GCA/CCA training command and had USN, USAF, USA and USMC 
students. Later the base was closed and moved to Glencoe GA.
