Been tracking on and off over the year but only now starting to look into improving my setup. Started off with a low cost usb stick with one of those tiny antennas, I cut the length to 52mm as suggested on a few forums with respectable results considering it was just placed beside my bedroom window.
I’ve since purchased the FA pro plus and installed an AirNav antenna at high level outside (cant get up to the chimney yet which will be my next improvement), I’ve also installed graphs1090 and a few scripts to check on noise etc. After checking the new noise graph I could see lots interference from the GSM bands here in the UK between 800-820MHz and 920-940MHz, purchased the light blue FA filter which has cut out the lower band but not the 920-940MHz, have purchased the newer filter (dark blue) which has a narrower band and should in theory cut out all of the GSM noise.
One thing i need advice on is my performance charts. Im seeing a huge amount of red single message tracks, is this normal?
My current setup is Rasp Pi Model 3B+, Piaware 3.8.1, dump1090-mutability, multiple feed sites.
