Hi,
I have been running my tracking station for many years and have usually had pretty good performance. I have a homemade 1/4 wave ground plane which is amplified due to a long run of RG6. I use the FA Blue dongle into a Pi running the Debian version of 3.8.1.
For a while now I have noticed I am no longer the top feeder in my area. Others get a few more aircraft, but they have significantly higher position counts. All of the feeders with stats better than mine seem to use the SDCard version of PiAware. Is this just coincidence or is there something better about the SDCard version that accounts for the higher position counts?
Are there settings I should check? Gain seems to be the most important knob, and if I set it too high, my message rates plummet as I generally have a lot of nearby GA traffic. If I set it low, I lose a lot of range (before many GA aircraft had ADSB I regularly had traffic out to 250 mm, but now with lower gains I see little outside of 150 nm).
My site is 72026. Any ideas what I should try?
