What is this?

GopherTrunk is a software-defined-radio scanner that follows digital trunked-radio voice calls and decodes them to audio. It runs on a pool of RTL-SDR (every osmocom tuner), HackRF (One / Jawbreaker / Rad1o), Airspy R2 / Mini, and Airspy HF+ dongles, has no C dependencies at build or runtime (no librtlsdr / libhackrf / libairspy / libairspyhf / libusb / libasound2 / libmp3lame), and ships as a single ~10 MB static binary for Linux, macOS 12 (Monterey) or later, and Windows.

Completed calls stream to Broadcastify Calls, RdioScanner, OpenMHz, and live Icecast / ShoutCast mountpoints out of the box. Why does this exist? Read The Story of GopherTrunk.
