Turn Raspberry Pi’s GPIO into an FM Transmitter

I know nothing about how this all works, how do people know who did it / where it came from? I presume its possible to get a rough location but in a built up area I'd imagine its pretty much impossible to find the person that did it unless it's left running right?

If you're interested, Hams do an activity called a "Foxhunt" where they're trying to triangulate the position of a broadcasted signal. It's sort of like wargaming, but for Hams.

This, in conjunction with whoever owns the plot of land the offending device happens to live on, determines who is to blame when someone is broadcasting illegally.

Here's a link describing the activity, in case you're interested: https://hamradioplanet.com/what-is-a-fox-hunt-in-ham-radio/

If you are blocking an essential services channel (eg Aircraft, Police, Ambulance, military), the authorities can get a triangulation (within meters) on you in just a few minutes.

You can use radio triangulation to determine where the signal source is while it is transmitting

Unless the transmitter is moving.
