Hi,
I would like to listen to the conversations from behind a wall !! , Just for entertainment !...
Please if you have parts and circuit details post it here.
Thanks.
 
You could bug the room with an fm transmitter and then hear the conversation on an fm radio with an earpiece....but then what's to stop others listening in by accident?

You could hold a sensitive microphone up against the wall and listen but that's a bit conspicuous....


Try the FBI if they have anything they can spare....
