I've just broadcast the starwars theme tune over 108FM using this https://github.com/markondej/fm_transmitter

But this one is very interesting it allows you to broadcast over from 5KHz upto 500MHz so your looking at FM & AM and a few others I believe https://github.com/F5OEO/rpitx

Just make sure you have looked up what the FCC (or foreign equivalent) allows for personal radio stations, you really don't want to piss those guys off.

I have been doing the cables not overly long so should be small enough to limit the area it's broadcasting, if it's not then I think a few people just heard the purge announcement
