Live demos use USRP B200/B210 and GNU Radio flowgraphs to capture and inject real signals: POCSAG and proprietary pager protocols are decoded and spoofed end‑to‑end; FM RDS/TMC items are collected and a 16‑bit key/31‑daily-keys lookup method recovers encrypted location entries; ADS‑B/Mode S streams drive a 3D Google Earth visualiser; a bistatic experiment maps primary radar returns (power lines, bridges, moving trucks) from a simple whip antenna; toll‑tag backscatter and car/keyless transactions are read; Arecibo uplinks re‑enable a heritage probe’s telemetry but thruster firings fail due to lost pressurant.
