Slope conversion is the hard part, once it's AM just about any energy conversion will do. abs(x) and |x|^2 are plenty nonlinear. [VIDEO]

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? [VIDEO] [LINK]
