[Milsurplus] ARC-5 Receiver and other tube questions

[mstangelo at comcast.net]

Wasn't the ARC-5/BC-45x series of HF Command Sets made obsolete by the British/TR-1143 design SCR-522 crystal controlled channelized VHF Command Sets?

If the VHF sets were available and the crystal manufacturing perfected earler I don't believe we would have seen the widespread production of HF Command sets.

Even though, the HF (and LF) Command set was my introduction to the world of surplus electronics and I still consider them the quintessential Avionic "Black Box" radio.
