rpitx is a software-defined radio transmitter that runs on a Raspberry Pi, generating radio frequency signals from 5 KHz to 1500 MHz using only a GPIO pin. It functions as an analog and digital modulator, an RF signal generator, a radio protocol emulator, and a signal capture and replay system, all without requiring additional hardware. The project achieves this by combining sample precomputation, direct memory-mapped GPIO toggling, and an interrupt-free timing loop to produce precise carrier frequencies and modulation patterns. It supports a wide range of modulation types including AM, FM, S
