You can build a public safety radio scanner for under $100 using the Raspberry Pi 4. This video walks through what digital trunked radio is and how to set up the hardware and software on the RPi 4 to decode Project 25 radio traffic and stream to an icecast server. The icecast server, running on a separate Linux system provides client access to the stream and archives the streams using systemd timers/services. You can use VLC on a laptop or phone to connect over WiFi to the Icecast server and listen live to public safety radio traffic. In this video, Rich Lucente shares his experiences assembling and operating this system. Watch and hear what you can pick up.
