I m using an rsp2 on a raspberry pi and need to change the config setting to select port B and bias t.
I have the rps pi package installed, and I can invoke ADSb but its using the wrong antenna port (i need b because I have a lna mounted at the antenna)
where can I fing the config file to edit the settings? I have looked high and low on the PI,
I have a win10 version of dump1090 and can find it on my win machine
please help a raspberry noob.
