Aaron who created and maintains the DragonOS SDR Linux distribution has recently uploaded a new video where he uses a KrakenSDR to simultaneously receive and decode multiple aircraft tracking, telemetry/messaging signals including ADS-B, UAT, ACARS and VDL2.
In the video Aaron uses his WarDragon which is a Mini PC that comes preinstalled with DragonOS. It is currently available on his website for $220, or $550 including a carry case, and Airspy R2.
The video shows how to setup all the software including FlightView GUI which is a graphical user interface that allows users to manage and configure various Docker based aircraft-related services including tar1090, readsb and acarshub.
