A C program that transmits AM radio signals from computers and phones that lack radio transmitting hardware by generating precisely timed electromagnetic emissions from the processor. It demonstrates TEMPEST-style air-gap exfiltration and includes a browser-based demo and tune file format.

Use cases

• transmit AM radio from a computer without radio hardware
• demonstrate air-gap exfiltration via electromagnetic emissions
• test TEMPEST-style leakage from secured systems
• play tunes over an AM radio receiver using CPU emissions
• receive computer bus signals with RTL SDR hardware
• study electromagnetic radiation from microprocessors

When to choose

• researching or demonstrating air-gap exfiltration and TEMPEST concepts
• testing electromagnetic leakage of embedded systems like Raspberry Pi
• educational demonstrations of low-level hardware emissions

When to avoid

• you need reliable or long-range radio communication
• you need a compliant, licensed radio transmitter
• you need production data exfiltration tooling with real throughput
