    graphs1090 does not use mysql.

    collectd with rrd-tool uses a round-robin database for each parameter captured.

    Even if you are going to write your own data collection, it will be worth taking a look at this:

    You can also extract data from the database...

    It's the same code for handling the receiver, so same performance in regards to reception of messages.

    dump1090-fa can decode and show some more extended data.

    When you already have the graphs...

    Have you checked the local map?

    If you want some statistical graphs or a better map, checkout this thread:

    You're probably running 1.15

    The addons are based on the dump1090-fa json format, at least some of them.
    If you don't want the addons or different local map, no need to change.

    But there is no...

    what's the problem with the current setup?

    You can always switch to dump1090-fa: https://github.com/wiedehopf/adsb-scripts/wiki/Bundle-install-for-dump1090fa

    Then the dump1090 will run...

    I think you are assigned the closest airport (from FR24s list of airports).
    Then the flag is chosen according to that airport probably.

    So in short: tough luck!

    If you had the default dump1090 that comes with the image (1.14), the newly installed dump1090-fa should even improve your message count and range a bit due to improved demodulation.

    1.14 is...

    Glad it's working, i assume you installed dump1090-fa as well DarkBlue?

    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:

    This LNA filters out quite a bit, so you might even be able to continue receiving ADS-B while you transmit: https://www.rtl-sdr.com/new-product-rtl-sdr-blog-1090-mhz-ads-b-lna/

    Any difference you find will be due to other factors.

    It is the same code, only other parts of the program have changed.

    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.
    Also the...

    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...

    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.
