Thanks to Brian KB9BVN for posting this link on QRP-L:
The film is entitled "Radio at War" and was produced by RCA. Obviously a film to make the folks at home proud of their soldiers and sailors. It was interesting to watch as my Dad was in the Signal Corp during WWII.
He never spoke too much about it; but I do know he was stationed in Great Britain for a while before going over to the Continent. He was working on the joint project between the Brits and the Yanks to further develop the new concept of RADAR.
Maybe that's where my Ham genes formed so long ago?
