Not radio related, but I recently saw 'The Monument Men' which, briefly, is about a largely American squad sent in at the end of world war two to try to recover artworks squirreled away by the Germans.
The characters spent a lot of time talking openly to each about their plans on phone (voice) field radio sets within easy listening distance of the enemy lines - not a wise thing to do, I would have thought.
But the one I really liked was the characters arriving at an American - occupied British airfield instantly recognisable to any warplane nerd as Duxford - it went OK to begin with, as the camera swept across a parked B17 ('Sally B)' and a P-47 Thunderbolt, swung past the iconic hangars and then finally paused on the WWII control tower, which had appropriately costumed officers milling around on the balcony.
Only problem was, they didn't remove the added-on modern storey with its outward-tilted tinted glass windows
