    Apologies for our light banter on the thread.
    Us folk who stay inland, always joke with those from Cape Town and their mountain. Then again, they call us Vaalies - referring to the Vaal River, the old Transvaal province, meaning "Over the Vaal(river)" (Vaal being a greyish/beige non-decrepit color.)

    But as PeterHR remarked: indeed a good location to get your antenna . SAFlyer, perhaps you can shed some light on antenna locations your side

    Jeez peterhr, I would give what to get my antenna on top of THAT little mountain!!!!

    Back on topic - for some obscure reason, Planeplotter is today not showing any data from my Pi - and I've changed nothing!

    Just another piece of software out the which also works on the Pi - ModeSDeco. What is also cool is that you can specify the dongle to use by selecting it's index. I have an idea of running 2 dongles on the Pi (different antennas) and then outputting to a single source

    What I am really liking is that there is also a modesmixer which can combine sources and feed to a single output.

    I have fr24feed_arm_le_241s running on my RPi and all appears sweet and dandy except thaI am left with a defunct child process every 10 minutes. If I do a ps -ef I get this:

    Code:

    pi        8222  7833  0 Mar09 ?        00:00:00 [bash] <defunct>
    I start the feed from a bash script which looks like this:

    Code:
    sleep 10
    export FR24AUTHIP=83.140.247.20
    /home/pi/modesmixer2/fr24feed_arm-le_241s --fr24key=416c0c6d1b30f4f2 --bs-ip=192.168.1.5 --bs-port=30003 > /dev/null &
    so after a 10 second wait while my modesmixer2 decoding programme starts the script starts the feed.

    Does anyone have an idea why all these child processes?

    I believe the defunct/zombie processes will only be purged when the owning process 7833 (fr24feed) exits, dies or gets killed - difficult to get rid of otherwise.

    I don't have access to my Pi presently to see if this is happening to me

    See the response in http://stackoverflow.com/questions/9...y-shell-script (suggests it might be a [harmless?] bug in the feeder)

    Hey folks. I just started feeding my data to flightradar24 and I'm a bit confused about what the site is telling me. I'm using dump1090 on Ubuntu 12.04 in combination with the fr24feed software. I got my sharing key today, put it all in, and everything looks OK. dump1090 is doing it's thing (I see all the traffic as I normally do), fr24feed is running and giving me messages such as "[i] sent 1 planes in 1 packets" or if there is nothing in range "[n] pinging the server" so I'm assuming that means that it's successfully connected to the server and uploading data. In addition to that my premium account went active a few minutes after I started running it so I'm sure it's connected.

    My confusion is on the feed stats details page. It says "Status: Online, since N/A", "Current upload rate: 0KB/s", and "No recent data for this radar". This makes me wonder if my data is actually being used.

    To make this even more confusing if there is no plane on the radar for a few seconds my status changes to "Offline". I'm not sure if there is a configuration issue on my end or if this is normal behaviour. Is there normally a delay or something showing the upload stats, etc?

    Apologies in advance if this isn't the right kind of post for this thread, but as a brand new user this seemed like the best place to start.

    Thanks for any advice/tips you can share!

    EDIT: I was impatient, it's showing all kinds of data now . Still "Online, since N/A" and 0KB/s upload but the graphs and things are there so I know it's working which is all I care about. Leaving this post here for posterity in case someone else comes along with the same questions.

    Agreed. I'm using a set of UHF/VHF TV "rabbit ears" at the moment. I'm new to amateur radio/SDR in general so I'm trying to decide if I want to buy or build an antenna. I've seen a few relatively simple DIY J-pole antennas around that people say are great for ADS-B but I'm still doing my research.
