I’m quite new to ADS-B tracking. I started last month and it all went really well. FA Pro Stick Plus, Raspi 4, spiderantenna and a nice range of more than 150 nm from within the building. From one minute to the other I lost the range down to 15 to 20 nm and the amount of aircrafts per day went down from >1200 to 200. This change happened when noone was at home. So no change of equipment, no change of antenna position, no SW change, nothing.
I thought of a broken stick sent it back. Yesterday I got a replacement and the range is still around 15nm. And also the amount of aircrafts is back at around ~200 per day.
Can anyone guide me around to figure out what happened?
I’m quite familiar with linux as os, so working in the shell is not a problem, but I don’t know where to start.
The SW I use is an install of openhabian (based on raspian), FR24 feeder, piaware and adbsexchange feeder.
