Years ago, people figured out Raspberry Pi’s can accidentally double as FM radio transmitters without a need for any radio front-end (if we don’t count a single jumper wire working as an antenna). They achieved this by tying a GPIO pin to a software-controlled clock around 100 MHz to modulate audio. This created a low-powered FM radio transmitter. Due to the pin producing a square wave instead of a neat sine wave, it also emitted weaker harmonics at 300MHz, 500MHz, etc., but any basic FM radio could pick up the audio. I wondered if a similar feat could be achieved by much less powerful Raspberry Pi Pico microcontrollers.
