SigDigger AIR-T Install¶

This tutorial will walk you through how to install and run the SigDigger tool on an AIR-T. SigDigger is a free digital signal analyzer for GNU/Linux and macOS, designed to extract information of unknown radio signals. It supports a variety of SDR devices through SoapySDR, and allows adjustable demodulation of FSK, PSK and ASK signals, decode analog video, analyze bursty signals and listen to analog voice channels (all in real time).
