Hope some of the experts can help.
Running a flightaware pro plus stick with black flightaware antenna. Cean pi install with piaware main software and fr24 feeder. Been getting really good hits with this setup. Thought I’d add a AirNav RadarBox 1090 MHz ADS-B Filter behind it since I’m in the NY/NJ metro area. Now with the filter I’m getting a weird phenomena. On piaware the total aircraft and positions dropped by almost 15%. Yet on fr24 I gained nearly 20%. Its pretty significant. You can see the results immediately after installing the filter. I remove it and everything evens out again.
Also noticed over all everything has dropped. Maybe due to the bad weather in the area.
I might just yank off the filter and leave it be. Maybe I’ll try the uptronics preamp with filter.
