    [FAIL] Receiver: down ... failed!

    Hi

    I am a total newbi to Raspberry Pi.

    After seeing a webpage describing how easy it is to feed data, I bought a 3B+ and a RTL-SDR V3-based kit. I setup the Pi with a new install, updated the system with sudo apt-get update and sudo apt-get upgrade-dist.

    I then ran the command

    Code:
    sudo bash -c "$(wget -O - hxxp://repo.feed.flightradar24.com/install_fr24_rpi.sh)"
    to install the feed. Followed the questions and filled out everything and I ended up with a working installation, or so I thought.

    I can access the webpage on the ip-address:8754 but it does not feed any aircraft.

    At first I checked for the fr24feed-status and get the following result:

    Code:
    pi@raspberrypi:~ $ fr24feed-status
    [ ok ] FR24 Feeder/Decoder Process: running.
    [ ok ] FR24 Stats Timestamp: 2019-08-10 12:19:18.
    [ ok ] FR24 Link: connected [UDP].
    [ ok ] FR24 Radar: T-VHHH169.
    [ ok ] FR24 Tracked AC:.
    [FAIL] Receiver: down ... failed!
    [FAIL] FR24 MLAT: not running ... failed!
    So, the Receiver is down, but I'm not quite sure as to why or how to fix it. When testing the dongle, it seems it is fine and working as described in a post here:

    Code:
    pi@raspberrypi:~ $ sudo systemctl stop fr24feed
    pi@raspberrypi:~ $ sudo systemctl stop dump1090-mutability
    pi@raspberrypi:~ $ rtl_test -t
    Found 1 device(s):

    Found Rafael Micro R820T tuner

    [R82XX] PLL not locked!
    Sampling at 2048000 S/s.
    No E4000 tuner found, aborting.
    When running the fr24feed directly I do get the following output with the ERROR: rmmod: ERROR: Module dvb_usb_rtl28xxu is not currently loaded. Is this the problem?

    Code:
    pi@raspberrypi:~ $ sudo systemctl start dump1090-mutability
    pi@raspberrypi:~ $ sudo fr24feed

    How can I fix this to connect to the receiver? Thanks a lot for your help.

    Since it was a new install, I tried again from scratch and followed the awesome and very easy to follow tutorial here by

    forum.flightradar24.com/threads/10232-How-to-Install-dump1090-mutability_1-15-dev-on-RPi

    Now it all works just fine. Thank you so much for that.
