I grew up in a house that was next door to a radio rebroadcasting facility, and we could definitely hear the radio station coming from the walls of our house sometimes, e.g. even their station identification so there was no ambiguity. I assumed it was the house wiring (mostly knob and tube) acting as an antenna. I'm reasonably sure that was AM, though. Was the sound you heard like either of these? https://www.youtube.com/watch?v=uo9nGzIzSPw https://www.youtube.com/watch?v=uo9nGzIzSPw https://www.youtube.com/watch?v=b9UO9tn4MpI https://www.youtube.com/watch?v=b9UO9tn4MpI
