My Antenna of the Radar Box is direct beside a small Airport on the roof of our house. But some of the aircrafts (cessna, helicopters etc) are not visible on the Radar Screen. They are shown in the list beside the radar screen (my flights) but not on the screen. Transponder ID, Callsign, Company and Status - everthing is shown in the list below the quick filter and also they are shown in the "my log" list... but not on the radar screen :-( I´m shure that they have Mode S
I don´t have any active filters for altitude etc.. How can i fix the problem?
Thx, Andi
