A how-to on making a simple AM radio transmitter using the ESP32 microcontroller by Bitluni:

AM Radio transmissions are based on a carrier signal which is modulated by the audio signal. It’s a very basic principle but prone to noise from the environment. Using the ESP32 it is really simple to generate an analog signal using the built-in DACs. With the provided code here just a wire as an antenna has to be connected to the pin 25 of the ESP32. The transmission will end up on the AM frequency ~835kHz.
