Github repo: https://github.com/BatchDrake/SigDigger

it's called SigDigger. plug in a cheap $20 SDR dongle and it decodes literally any radio signal floating in the air around you.

wireless mics. baby monitors. garage remotes. analog security cams. walkie-talkies. all of it.

→ demodulate FSK, PSK & ASK signals in real-time → decode analog video transmissions → listen to analog voice channels → analyze unknown & bursty signals live

it's built by one guy in Spain (licensed ham, EA1IYR). the DSP core, the GUI, the widget library, all his own projects, all open source.

Linux and macOS. self-contained AppImage means zero compilation to get started. plugins for Deep Space Network amateur reception, weather satellites, and AntSDR are one flag away.

signal intelligence work that used to require a Rohde & Schwarz analyzer. now runs on your laptop.

100% Open Source.
