[BC] German Radio Spying 1938

[wpio-fm]

We have a German music show hosted by an 85 year old lady who grew up in 
Berlin.

Along 1937-39, as kids they had to be sneaky to listen to BBC (British) 
radio and she remembers the Nazi's driving through the streets with a 
small dish on the roof top of their vehicle.

I first thought it was an RF device trying to pick up an I.F. signal, 
but then I wondered if it were just a highly sensitive and directional 
microphone.  Or it was just plain bluff, and it was neighbors who would 
report you.

I'd like to know if anyone knows what the the "litle dish" technology 
used at that time was.  Ruth says, if you were caught, it was bad news 
for you.
