    Hi all,
    I'm a newbie to rtl-sdr and raspberry pi.
    I just set up my first ADS-B receiver, using the scripts located at:
    github/jprochazka/adsb-receiver

    I am running dump1090-mutability, on Raspberry Pi 3, raspbian sketch w/ desktop.

    I have the following feeders working:
    - FlightAware
    - FlightRadar24
    - Plane Finder

    But I can't seem to get the ADS-B Exchange feed to work.
    I'm located in Hagerstown, MD - and am currently not showing on the feeder map.

    The contents of my "adsbexchange-mlat_maint.sh" file is: (location is redacted):

    #!/bin/sh
    while true
    do
    sleep 30
    /usr/bin/mlat-client --input-type dump1090 --input-connect localhost:30005 --lat XX.XXX --lon -XX.XXX --alt XXXXX --user gumanov --server feed.adsbexchange dot com :31090 --no-udp --results beast,connect,localhost:30104
    done


    Changed the feed URL above to bypass forum spam filter..

    Any tips on what the issue could be?
    Thanks

    Oh.. looks like I spoke too soon. I just appeared on the feeder map.
    So separate question then:

    Does the MLAT data back-feed (from ADS-B Exchange to my dump1090) automatically display in my live dump1090 map? Or does something need to get configured?
    Does the same apply for the FlightAware MLAT back-feed?

    Thank you!

    When you are getting MLAT data back - I believe traffic will appear on your local display as well. I do not know about FlightAware ...


    Welcome to ADSBexchange and thanks for feeding!

    Just tested this, and yes you are correct.
    I can see both FA and ADSB Exchange MLAT back-feeds on my dump1090 display automatically.

    One thing I've noticed so far is that dump1090 displays "FA MLAT "aircraft with correct heading(track), but all aircraft from "ADSB Exchange MLAT" feed have an unknown heading. Track displays "N/A".
    Any thoughts?

    Works fine in VRS - ADSBX MLAT feed displays correct heading in VRS.

    Thanks
