In season 3, Episodes 7 and 8, resistance members parachute in from London. They are equipped with what looks a lot like a paraset. One of their tubes develops an open filament. The Germans engage in radio direction finding. The Morse code is fairly good (but not great). All in all, there is quite a bit of radio-related material.
“A French Village” is a very well-done series. But it is (of course) quite dark.
