Of course, on the RPI there is the good ole GPIO4 abuse: https://tutorials-raspberrypi.com/build-raspberry-pi-radio-t... Works a lot better and has been around a long time.

From reading the comments there it seems newer RPi (>3) don't work for this or mangle the GPIO port in some way to prevent this. I do have some 3s lying around so I may try this soon.

I used this to jam mobile phones by tx'ing on a harmonic of the band they were using (CDMA iirc)

Just to see if it would work and then a little science demo for my kids. I never did it outside of the house.
