How to Build a Raspberry Pi FM Radio Transmitter
https://circuitdigest.com › microcontroller-projects › raspberry-pi-fm-transmitter
So by writing a code to perform frequency modulation using the spread-spectrum clock signal we can tweak the Pi to work as a FM transmitter. The modulated signal will be given out through the GPIO pin 4 of the Raspberry Pi. We can simply attach a normal wire of 20 cm maximum to this pin to act as an antenna.
One might be able to 3D print fractal antennae, but my print only does 0.2mm resolution.
