Does anyone know about a 200MC receiver that was made is a case that fit a ARC-5/SCR-274 receiver rack? I had a couple of these around 1960. I gave thought to converting one to 220MHZ operation but we had no local 200MHz activity and I never found a manual for it. Bob Macklin K5MYJ Kent (Seattle), Wa, "Real Radios Glow in the Dark"
