It's not bas extreme as a filling, but I've encountered several accidental radio receivers over the years. A solar powered race car I worked on had a problem with going to 100% throttle whenever someone transmitted on a handheld radio nearby. A stereo audio pre-amp I built from a kit would readily pick up AM stations. When I first visited my in-laws home, I discovered that their subwoofer was preaching evangelical gospel.

I've got a few guitar distortion pedals that can pick up AM when the knobs are in a certain position. It's fun to turn it on in between songs at a gig when we're checking our tuning.
