AN/PRC6 vintage military radio.

New video here:

A few images and information regarding the use of this set.

Crystal conrolled between 47 - 55 mhz (hence covering 6 meters) and with ~1/4 watt output. The set operates from 45vdc on receive and 90vdc on transmit (the extra 45vdc going to the 3B4 miniature PA valve).

All filament voltages use 1.5vdc. -4.5vdc is used for bias in the audio stages.

13 subminiature pencil valves and one B7G base miniature for the PA.

I now have a pair and set -to -set range, at best, is about three miles in open country. The unit above is german surplus, although they also used their own, very similar, licence-built 6 channel sets (PRC6/6).

Greece too made extensive use of them (PRC6-E) and one of those is currently receiving in the shack.

@XtalQRP yes you are right , in open field you should get about 3 miles range ; but under " military " conditions the range was greatly reduced , to about a mile , the other trouble with that radio is the battery going dead very fast ! I remember also a lot of failure with the tube filaments .

Funnily enough, this set had was dead when it arrived. The culprit? O/C heater filaments in one of the subminiature valves...

Using alkaline cells I get around 14 hours use at a 1:6 tx/rx ratio.
