Installed the RTL-SDR 1090 LNA this morning to see how far out the antenna can receive (195 miles post-install). My setup uses the blue pro stick with the FA 1090 antenna up in the attic. LNA is up at the antenna. Prior to the LNA install, strong messages approximated 20% with auto gain. Post LNA install, it’s running 67-70%. Also, almost no close-in GA traffic is showing despite a good day to fly. Is there a correlation with the strong message count and lack of close-in traffic?
I set the gain (currently 39) based on a rough aircraft/distance count. Not sure how to proceed other than playing with the gain to see if the GA flights show up again. Advice appreciated on what else to tweak.
