yeh, Fa’s discussion search is not the best.
It doesn’t seem to do partial matches well.
You can do 978 UAT on the same RPI(RPI2 is better. much more CPU). I found it easier to setup that way(dump1090 or piaware tries to steal the USB Dongle at startup)
Look at
github.com/jprochazka/adsb-feeder
ads-b-flight-tracking-f21/ads-b-feeder-project-setup-scripts-t36532.html
He has a script to set everything up in one go.
It also installs the better Mutability version of dump1090.
This colours the aircraft base on Alt and allows you to sort based on country, call sign, squawk, distance, altitude and more.
You can also enable 2.4Mhz bandwidth mode.
I get about 25% more traffic with the mutability version of dump1090.
