[MRCA] Military radios

[KENNETH R ENGELBACH]

I have recently became interested in Military radios, as I have come into 
possession of a few.  I am really interested in finding out information 
about one in particular.  I have a PRC-1 radio, I'm told it was a spy radio, 
but I do not know for sure.  I would greatly appreciate it if I could find 
out any information on it or how to use it, I've seen a video on YouTube, 
but it does not explain how to use it or even power it.  Thanks, Ken
