Now this has serious potential! Turning an SDR-based receiving system into a mobile hardware scanner with an old laptop and some free software.
In this video I demonstrate using an Airspy Mini along with the free trunk-recorder and rdio-scanner software. This allows you to set up a really neat interface for selecting which channels to monitor. It works with conventional and trunked networks. Here I am using it on a large P25 simulcast (LSM) system in my area.
I used DragonOS Focal as the Linux distribution.
