One thing I have observed is that the input to VRS from ports 30005/30106/30105, after conversion to Basestation MSG format by VRS, has Call Sign missing. Is the Call Sign supplied by databases of VRS and dump1090 for their map display?
Output from VRS after converting input from dump1090 port 30005 to Basestation MSG format.
