Gentlemen, good day! I use the ADSBX image and want to add the command option "--modeac" to readsb.... if i use Code: sudo nano /etc/default/readsb i'm able to add the option, but after restart of the service and also after a reboot of the pi and check the status of readsb, the --modeac parameter is still missing in the shown command line! Any hint what i'm doing wrong? Tnx in advance!
