    After a couple of days hacking away at this, I'm really stuck getting things going on the RPI4.
    I have the pretty desktop with faux mountain background, but that's all I can do.

    The first thing that happens is at the two green face test only shows one green face and one
    red one. Can this be fixed?

    Then it calls for ab IP address but not how to obtain how to get it. How do I show what IP is
    assigned to the PI?

    Then the second question is, how exactly do I do the following?

    Edit adsb-config.txt located on the SD card after burning image file.

    I have the dongle plugged into the PI4 since before boot. I'd like to get this on the air as I live between class D & class B airports, and have much air traffic over my house.

    Thanks for your help!

    The image I downloaded is: 2021-05-07-raspios-buster-armhf-full.img
    It's 8gb+ large and the requested upgrade during installation has been done.

    I have the normal Raspberry PI 4, with 4gb ram. I'm hoping to use my
    NooElec R820T SDR & DVB-T NESDR Mini as the receiver.

    I'm more than willing to download & install another image to make these
    otherwise idle items work. I am not very experienced, and need clear
    instructions to get it on the air.

    Thank You!

    https://github.com/wiedehopf/adsb-wiki/wiki/Raspbian-Lite:-ADS-B-receiver

    Just follow this guide, it should be straight forward.
    As you already have the base image, the first thing from that guide above would be:

    https://github.com/wiedehopf/adsb-scripts/wiki/Automatic-installation-for-readsb

    Once that decoder works, you can start feeding:
    https://github.com/adsbxchange/adsb-exchange#install-the-adsbexchange-feed-client
    https://github.com/adsbxchange/adsbexchange-stats

    Note that usually people run the pi without keyboard monitor and just connect via SSH to configure and browser to view the local webinterface.

    I'm trying to reply, with links and such, but I keep getting rejected because
    my replies are "spam-like" with "inappropriate content". So frustrating after
    spending time to explain what (exactly) I did and tried. I hope this one will
    get through. are there specific characters that trigger this? Since I've never
    used Gethub before and I didn't know which links to start with above, this
    may be the end of the road for me...

    You start with the first one, then continue with 2nd and 3rd one:

    1: https://github.com/wiedehopf/adsb-scripts/wiki/Automatic-installation-for-readsb

    2: https://github.com/adsbxchange/adsb-exchange#install-the-adsbexchange-feed-client

    3: https://github.com/adsbxchange/adsbexchange-stats

    This link i put at the top is the general guide with lots of useful links: https://github.com/wiedehopf/adsb-wiki/wiki/Raspbian-Lite:-ADS-B-receiver
    As you can see the above 3 links are mentioned in this guide.

    If that wasn't already clear, the commands are all for the command line.
    Usually you'd copy them and paste them in putty.
    But as you have the gui, open each webpage on the RPi.
    Open a console / terminal (black box in the shortcuts i believe on RPi gui).
    If the page shows you a command to install, copy it and paste it into the terminal.
    To paste into the terminal should work with right click -> paste or Ctrl-Shift-V.

    That worked just fine... Thank you for your help.
    I'm feeding now with the little whip antenna that came with the dongle.
    Time to get a real antenna -
    Thanks again!

    One more question. In an effort to get better reception, I replaced the little 4.5 inch whip antenna with a random length 'long wire' of about 3.5 to 4 feet high.
    Now the reception which is indicated by an aqua colored 'ragged star' pattern, but -NO- aircraft are displayed after a reboot.

    It worked just fine until I re-booted the Raspberry PI, after installing the new 'antenna'. Is there something you must do to get the tar1090 to display the aircraft?

    The reception outline is the maximum over the last 24.
    To reset it use this command:

    sudo systemctl restart readsb

    Anyhow you're saying something is not working, check the log as described on the page you used to install the decoder: https://github.com/wiedehopf/adsb-scripts/wiki/Automatic-installation-for-readsb

    Common issue is low voltage.
    In general i'd recommend connecting via SSH and removing the monitor and keyboard ....

    Things are working well now. Thanks again for your help.
    Only thing I miss are the origination and destination airports
    that the other similar services show and also who the owner
    of the aircraft. Is there some kind of plugin or upgrade to
    see these things?

    A long wire antenna is unlikely to improve reception a single element antenna wants to be about 69mm long the antenna that came with the dongle is to long
