    DIY Feeder problems

    Hello there guys,

    I am trying to build a feeder using a rPI and a DVB dongle but I encountered some problems and I'm not sure of what can I do now.

    The dongle I am using is an generic one that also had an antenna. My question is how can I figure out what is the problem, whether the dongle or the antenna are not good?
    And if the one of them are not supported, what can I do to fix them?

    Here is a picture of the dongle&antenna:

    Thank you in advance for your answers!

    What software have you installed on RPi?

    Please run this and show the output:

    Code:
    sudo bash -c "$(wget -O - https://raw.githubusercontent.com/wiedehopf/adsb-wiki/master/rtl_test.sh)"
    Or you can run rtl_test manually like described here:

    A start could be to check if you have the right tuner in your dongle. I bought a tuner from china that was mislabeled and unable to receive ADS-B signals. Search for "How To Test If Your DVB-T RTL SDR Dongle Is Healthy" (don't think I can post links yet here due to new account)

    dump1090-fa and dump1090

    The rPI is running Raspbian Stretch.

    Lost samples in the first 2 seconds after starting the test are common and not a problem!

    More than 2 lost samples per million or other errors probably mean the receiver isn't working correctly.
    Try another power supply before condemning the receiver though!

    Your power supply is not adequate, consider the Official Raspberry Pi power supply.
    Any constant voltage supply with 5.1 to 5.2 Volts and 2.5A capability is also a good choice.
    Inadequate power supplies can lead to many different problems!

    Most likely you are running dump1090-fa and dump1090 at the same time.

    That won't work properly.

    Follow the guide or use the script described as on this page:

    I posted my rtl_test output but the post needs to get approved.

    Regarding running both dump1090 and 1090-fa, I think only fa is running by default. The behaviour was present event before having the dump1090.

    Edit: wiedehopf, that's what I used when I firstly installed dump1090-fan.

    Luckily I was still up (2am!!) to approve

    I've highlighted the issue, It's not the right stick type.
