History:

The American one-channel portable radio PRC-6 was modernized again and again, using the same housing. The German BW used the 6-channel PRC-6/6 . Both still used tubes.
Telemit built a one-channel solid state "banana", called PRC-6T. Telemit also built the radio shown here:
 
  AN/PRC-6/180/GY , a 180-channel-"banana".
 
PRC-6T as well as PRC-6/180 were built for former friendly states and never were used in the NATO. That is why they are so hard to find.
Both need only 12 V to run, provided from 8 D-cells. (PRC-6 and PRC-6/6's battery had to provide four voltages, 90 V, 45 V, 4.5 V and 1.5 V.)
