Raspberry Pi SDR
summary
Raspberry Pi paired with cheap USB radios (notably an RTL‑SDR dongle) becomes a portable radio lab: builds include a touchscreen frequency analyzer running Adafruit’s “freakshow” Python UI, a PiAware ADS‑B receiver using dump1090 that logs 1090 MHz aircraft transponders (claimed multi‑hundred‑mile range with a good antenna), and an APRS igate/digipeater stack using Direwolf. Higher‑end options mentioned are HackRF (half‑duplex) and LimeSDR (full‑duplex). Listening is legal; decoding pager or encrypted traffic and transmitting without proper license is not.
