SignalsEverywhere: Driving around with KerberosSDR and Locating a P25 Transmitter

On this weeks episode of SignalsEverywhere, host Corrosive tests out our KerberosSDR coherent RTL-SDR unit for radio direction finding. If you didn't already know KerberosSDR is our experimental 4x Coherent RTL-SDR product. With it, coherent applications like radio direction finding (RDF) and passive radar are possible. Together with the KerberosSDR direction finding Android app it is possible to visualize the direction finding data produced by a KerberosSDR running on a Pi3/Tinkerboard.

In the video Corrosive uses the KerberosSDR together with the recently updated companion Android app to determine the location of a P25 control channel. By driving around with the app constantly collecting data he's able to pinpoint the location within about 15 minutes.

If this interests you, we also have some more driving demo videos available here.

Direction Finding With Kerberos SDR

In addition to his video, Corrosive has also created a very useful calculator that can be used to calculate the required antenna spacing for a circular or linear direction finding array that can be used with the KerberosSDR.

    This video is amazing. I have a KerberosSDR on a Tinkerboard-S and another on a RasPi 3+ and they are the cutting edge for RDF. Our club bought 4 KerberosSDR’s for hunting down some bad actors in our area who are intentionally jamming repeaters. We have been using an app called SigTrax to create a team of mobile DF stations. Is there anyway to make the KerberosSDR compatible with SigTrax so that we could automatically ‘network’ our mobile DF stations? It would help us to find the bad actors much quicker.
