That’s kinda bad advice.
The FA setup described includes the decoder.
So does the default rbfeeder setup.
So if you do that install, rbfeeder will need reconfiguration. (not that it’s super complicated but it should be mentioned)
I’ve got install scripts for readsb and dump1090-fa, both capable decoders (they share quite some code), the scripts will reconfigure fr24feed / rbfeeder to use them without the user needing to do anything: Raspbian Lite: ADS B receiver · wiedehopf/adsb-wiki Wiki · GitHub
Oh nvm … don’t know about 360 stuff, they have literally zero documentation.
Anyhow if you want to keep the old UI, installing dump1090-fa can be an issue.
