[ARC5] Need Information

[Bob Macklin]

Start by understanding the ARC-5 units were manufactured for the US navy. 
The SCR-274 units were manufactured for the USAAC/USAAF. SCR stands for 
"Signal Corps Radio".

If I remember right the ARC-5 transmitters were plate modulated and the 
SCR-274 radios were screen modulated.
