Mayhem is open-source firmware for the HackRF One combined with the PortaPack H1/H2/H4/H4M add-on, turning the SDR into a standalone touchscreen RF device. It is a feature-rich fork of Havoc/PortaPack firmware with many apps for receiving, transmitting, and analyzing radio signals.

Use cases

• explore and analyze radio frequency signals with a portable SDR
• receive and decode RF transmissions without a computer
• replay captured RF signals for security research
• flash custom firmware onto a HackRF+PortaPack device
• use a handheld alternative to a Flipper Zero for RF work

When to choose

• you own a HackRF with a PortaPack H1/H2/H4/H4M and want a maintained, feature-rich firmware
• you want standalone RF reception, transmission, and analysis without a laptop
• you want an actively developed fork with frequent nightly releases

When to avoid

• you need SDR software for a different radio than HackRF+PortaPack
• you want a stable production-grade product rather than experimental nightly builds
• you need legal-compliance guarantees - transmitting with it can violate radio regulations
