    Hello all,

    first a big thank you for the great adsbexchange site. I'm a flightradar subscriber since some years and found now this great site here.

    So I started last weekend with setting up the adsb image on my raspi 2+, attached my SDRplay receiver with a quarterwave antenna for 1090 Mhz, everything looks good, I receive about 20-30 Airplanes when I check it via SSH CLI. However when I connect to the Grafana Interface my Pi stats are ok, but feeder stats show no data. Feeder connection and MLAT connection are both green. Also when I connect to my Pi at 192.xxx/tar1090 I get a white screen, only with an empty table on the right side.

    Looking for any idea or help in solving the issue!

    Many thanks,
    Frank, DD7ZT

    Which feeder stats?
    Screenshot?

    You also haven't really described how you configured everything and which software you are using.

    How do you check on the CLI?

    local map empty

    SSH CLI command:
    sdrplay_dump1090 --dev-sdrplay --quiet --net --interactive --fix --mlat

    output:

    Software I just flashed the adsb buster Version adsbx.1.0.3 on my SD Card.

    Thanks!

    Well this is not how this works.

    This actually starts the decoder: sdrplay_dump1090 --dev-sdrplay --quiet --net --interactive --fix --mlat
    The decoder that's installed for the image to work can't use an SDRplay, so it's not running.

    Really the SDRplay is not supported by the image, maybe come by the discord and we can get it configured so that it works ....

    Really the easiest and best thing to do would be using an rtl-sdr compatible device.
    SDRplay is probably somewhat wasted for ADS-B and i'm not sure about the performance in regards to ADS-B either.

    Ok, thanks so far. My SDRplay was actually not planed for a longer period here. If this is my problem here thats ok for me. No need to invest further time. I had already a look for something suggested. So I will order a rtl-sdr, improve my antenna and install it on the roof. I will update the thread when I replace the SDRplay.

    Check the coax you'll use for attenuation at 1000 MHz.
    The entire run shouldn't have more than 5 dB attenuation, more optimally less obviously ;)

    It's suggested to either put dielectric grease into even an (already supposedly watertight) N-connector or just use self-fusing tape to waterproof the antenna connection.
