SDR Monitoring Station¶

A software-defined radio setup I'm building in my car in Eau Claire, WI. For monitoring public service radio or ADS-B flight data, or whatever else I think of.

Hardware¶

• HackRF One - wideband SDR receiver (1 MHz - 6 GHz)
• V-dipole antenna - probably not optimal but it's the antenna that I have that works

Capabilities¶

P25 Trunked Radio (trunk-recorder)¶

Monitoring the WISCOM VHF trunked system (Eau Claire Police, UWEC PD, and other public safety channels). Running trunk-recorder in Docker, decoding P25 control channels and recording calls.

ADS-B Aircraft Tracking¶

Readsb built from source with HackRF support and tar1090 for web-based aircraft visualization.

ISM Band / 433 MHz¶

rtl_433 for picking up weather stations, tire pressure sensors, and other ISM band devices.

HF / Shortwave¶

Status¶

I've been messing with live audio playback of trunk-recorder calls via inotifywait. I'm trying to bundle everything together into a cool wrapper script for trunk-decoder that can do everything without too much extra modification. Right now I can handle recording, monitoring both new recordings and logs, swapping and editing config files in a menu/library, and providing some statistics on collected data.
