    You can have multiple stations per account on FR24 and FA.

    But if it's the same location, another station is probably not required.
    No matter enjoy the upgrade on both accounts i guess :)

    You need to reduce the gain.

    Try a gain of 28

    The percentage mentioned in the first graphs should be 1 to 10 percent, not 55 like yours.

    It just doesn't work if you're not on armhf or maybe even just not on a Raspberry Pi.

    pi24 image is not the correct Raspbian version for the RPi4 and therefore does not work on the RPi4.
    At least that's my understanding.

    You'll need to use Raspbian Buster Lite and then run the...

    You can't run FR24 MLAT twice on the same device.
    The 8754 webpage will only work once.

    It's not resistance, it's impedance.
    Going from one impedance to a different impedance creates some attenuation.

    I won't add links to FR24, just type in the call sign or tail number, it's simple enough.

    Why don't you just test if you can see a difference?
    Might be better to leave it off if you are using a VM, might be some USB problems which make MLAT go bad.

    So just leave it off.

    The filter only comes after the internal LNA, which is often too late.
    With a discone i suspect the internal LNA will get overloaded and produce noise on all frequencies.
