Hi all, I’d like to ask for your opinions. Currently, my feeder setup is an OrangePi Zero LTS with Piaware 4 on Armbian, RadarBox Outdoor ADS-B Antenna, and ADS-B RTL-SDR Discounted Bundle (got it last month from RTL-SDR Blog), and a FlightAware Dual UAT/ADS-B filter. I wasn’t able to acquire the FlightAware ADS-B only filter due to lack of stock and I thought it’d do just as well (stupid decision). Also apparently I live within 200m of a cell tower (this fact was just recently known to me).
When I went to finish the setup this morning, I was greeted with an awful message rate (avg at 8msg/s, maxing out at 20) with unreliable tracking, even though I live within 20km of a major international airport (CGK/WIII). Then, I went ahead and did a spectrum scan and got these results:
scan w/ FlightAware Dual UAT/ADS-B
So it seems to me that the ~900MHz GSM signal is overwhelming the 1090MHz signal. And I’d have to get a better filter/dongle. In your opinion, would something like this Aliexpress filter work?
EDIT: Removed a sentence which didn’t fit my current circumstance
