We are not seeing ADS-B equipped aircraft on our two antenna system (978 and 1090) until they are more than a few miles away from our gliderport, Soaring Club of Houston. I know for certain that the aircraft are transmitting properly. I can see the aircraft on my iPhone (almost live) via the FlightAware app, down to 200 feet AGL. All the aircraft have clean PAPR’s (Public ADS-B Performance Reports). I cannot see the above aircraft (four total - all 1090) on the local computer hooked up to the two orange FlightAware boxes. This has been the case from the beginning until now, about four months. At first, I assumed that the problem existed in our local aircraft ADS-B systems. Now, I’m pretty darn sure that the problem is not on the airplane. I’m guessing that the problem is on the user end, me.
Yet, we can see almost hundreds of other aircraft up to 100+ miles away.
Is there setting that I need to change?
Today, I watched a 1090 equipped airplane start its taxi (transponder ON) that was parked 50 feet from the antennas, takeoff and then fly towards the NW. The airplane didn’t appear on our local viewer until it was about 8 miles away. Yet, I could view the airplane almost live on my FlightAware app on my phone.
