If you have set-up ModeSMixer on your Feeder, it is very possible, that you own more than one Feeder and you split data into one Radar. ModeSMixer allows you to Re-Broadcast data to RawFlight.
WHAT IS MODESMIXER?
ModeSMixer is free tool that allows to merge data from 1+ Feeders into one merged Feed. Also, it accepts data in BaseStation and Beast/AVR (binary) format. This application is pretty lightweight and can work on Windows and on Linux.
To start feeding this way to RawFlight, you simply need to execute one command:
./modesmixer2 –outConnect beast:rawflight.eu:48581
