    Once you have dump1090-fa installed using the bundle, the underlying image doesn't matter.

    Installing dump1090-fa first via the bundle (or another way) is required for all addons except the...

    tar1090 shouldn't interfere with the graphs. neither my graphs nor other graphs.

    If you switched from dump1090-mutability to dump1090-fa, you'll have to delete collectd.conf:

    The demodulation is the same code as far as i know.
    So should be the same message rate.

    dump1090-fa can show you some additional parameters like IAS and TAS and some other details.

    It quite depends but i would imagine that the range won't go down when you reduce the gain by 5.

    The range will only significantly decrease once the weakest signal is around -25 to -30.

    Sometimes it's a tradeoff between receiving very close and very distant aircraft.

    Normally i recommend 1% to 5% Messages >-3dB.

    That's also what my automatic gain adjustment adjusts to, it's...

    Hello, i've been maintaining some addons for dump1090-fa, i've linked them sometimes but they might as well have their own thread here.
    They are meant for Raspbian Stretch and later, but they should...

    You'll have to run the install again and it's sufficient to select installing the web interface and the graphs.

    Purging dump1090-fa will not purge its dependencies like lighttpd.
