    are you running the image from the first post of this thread?

    can you show the output of (redact the line with the fr24key):

    cat /etc/fr24feed.ini

    also the output of the following commands:

    grep -i gain /etc/default/dump1090-mutability

    pgrep -fa dump1090

    Hello,
    thank you very much. Now it's ok..
    The gain I must setup in menu fr24 and in dump1090 from "max". to my choice.
    But the gain must be from the list, not -10dBi, or 10..
    This is supported list of gains
    Supported gain values (29): 0.0 0.9 1.4 2.7 3.7 7.7 8.7 12.5 14.4 15.7 16.6 19.7 20.7 22.9 25.4 28.0 29.7 32.8 33.8 36.4 37.2 38.6 40.2 42.1 43.4 43.9 44.5 48.0 49.6
    sudo nano /etc/default/dump1090-mutability
    setup all you need
    press ctrl+x to exit and save Y
    sudo service dump1090-mutability restart

    grep -i gain /etc/default/dump1090-mutability
    pgrep -fa dump1090
    This sudo will help me, thanks.

    That is why I gave you the command for --gain 2.7, because you said 2.7 and that is valid

    Hello again,
    I have a question, how many receivers is needed for coverage area around 350nm..
    Is it only 4? For MLAT coverage..?
    Or more plane=more receivers?
    Because my country isn't so big, so we have around 189 receivers..Isn't so much?
    Thank you very much for the answer.

    Are you loging to Pi using a Monitor connected to RPi by a HDMI cable, and a keyboard plugged into USB port of RPi?

    Hello,
    how often do you change micro SD card? How lifetime the uSD is? I have 16GB.. Because I read something about lifetime and cycles in Rpi..
    Thanks..

    I personally don't know anything about this....but searching the forums/web would probably turn up some good general guidelines that would help you.

    Don't worry about it, i think the problem was mainly with the first RPi generation or the micro sd-cards available at the time.

    You shouldn't have to change it at all and if it quits on you it'll likely not be related to how much was written to it.
    But they are cheap and you could always transfer the contents to a new sd-card every 3 years or so?
    Might be statistically useful when you don't want to have to react to a failure.
    (Or make a copy of the sd-card and keep the second one around so you can switch in case of a failure)
