[ARC5] CBY-46104 Receiver

[Gordon White]

       The original   Command receivers were designed to cover eight 
frequency ranges from 190 kc to 27 mc. To my knowledge only fifty of the 
complete eight-receiver sets were built, under nomenclature RAV. Some of 
these have actually surfaced. The most rare receiver is the 9-13.5 mc 
model. I have only seen one, and it  was pretty much a wreck.  I have 
heard that these were used early in the War in patrol blimps. The RAT 
and RAT-1 receivers covered 13.5-20 and 20-27 mc. The more common 
SCR-274-N and AN/ARC-5 receivers ran from 190 kc to 9.1 mc, plus crystal 
controlled  vhf sets and tuneable vhf receivers, 100-125 and 125-156 mc.

    There were various rather minor differences in the receivers under 
the various different nomenclature.

    Some hand-built  Type K receiver prototypes had slightly different 
frequency ranges.
