Just put up a video of one of the AN/GRC-9 that I have been playing with. Interesting radio and it appears there were many produced and many more options for powering by AC, Dry Battery with hand crank and Vehicle. Somehow get the feeling
that the GRC-9 was something like the PRC-25/77 of its day.

Also attached an image from the FM, like the picture! Very sexy for a nineteen fifties radio with the M-38 and all that. Only thing is not certain if the vehicle in the circle is a M-38 or maybe a GPW looking at the bumper?
