Wrote Stretch Lite image to microSD card, booted RPi with it, and ran J Prochazka’s script
(1) The script did NOT proceed further unless I chose one of dump1090 to be installed. I chose dump1090-mutability and then dump978. Installation successfully completed, but dump978 map not displayed at
(2) Ran J Prochazka’s script again, and installed web portal. Now dump978 map visible at
(3) Removed the dump1090-mutability (which was force-installed by J Prochazka’s script) by following command
sudo dpkg --purge dump1090-mutability
sudo rm -rf /usr/share/dump1090-mutability
Now the dongle is in use by dump978 as dump1090 has vanished.
However due to no UAT 978 traffic at the moment, cannot say if it is working or not. Will have to wait for say half a day or more. Even the ADS-B 1090 traffic is almost zero here at this hour.
