    Ok.. re-did --signup.. Its verified my key but now im getting

    pi@neePi ~ $ sudo service fr24feed status
    [ ok ] FR24 Feeder/Decoder Process: running.
    [ ok ] FR24 Stats Timestamp: 2015-07-02 06:14:57.
    [FAIL] FR24 Link: connecting ... failed!
    [ ok ] Receiver: connected (80 MSGS/0 SYNC).
    [FAIL] FR24 MLAT: not running ... failed!

    On looking at the website:8754 it is receiving data (i can see tracked aircraft).. but not transmitting it i think...

    Edit x 3 .. Changed back to the default DVBT stick (default) and now it connects.. Still failing on the MLAT tho..

    iamnothere, neebong,

    armv7l should work fine on B+, we tested that.
    The problem you have may be related to a still running previous instance of fr24feed and/or dump1090.

    Please try to check it:
    Code:
    $ sudo service fr24feed stop
    $ pgrep -l fr24feed
    $ pgrep -l dump1090
    If anything of it is still running after you issue stop command, please try to kill it explicitly (PID will be given by pgrep output):
    Code:
    $ sudo kill -9 PID
    And then restart fr24feed:
    Code:
    $ sudo service fr24feed start
    If it still doesn't help, please enable logging through signup wizard and post the output here. You will be able to specify the path for logs, log name will be fr24feed.log.

    StDt,
    iPhone GPS would be just fine for that.

    This error:
    Saving settings to /etc/fr24feed.ini...ERROR
    is most likely related to incorrect file permissions. pi user should normally be allowed to read/write to /etc/fr24feed.ini
