    Oh that antenna is just for testing off-site. It does not really matter.
    Under the roof, it is connected to a much better antenna.

    With the fruit crate, i have just to pick a single object and plug it of the power socket, when i need to tinker with it.

    Your Google Translator is broken.
    The matter was that the DFLD organization won an award of 1000€ for its citizen-based aircraft noise monitoring system, that is operated independently of the airline and airports industries.

    You can surely apply for that award as well: you might provide a network of about 300 noise monitoring stations, lease a mainframe to aggregate the results and compute the daily, weekly monthly and yearly statistics for each station according to the strict rules of the european aircraft noise directive.

    You might have a look on its international variant
    Code:
    http://www.eans.net/En/index.html
    .

    The DFLD real-time noise radar (their terminology) is a map with flights à la Flightradar plus a real time display of the noise measurements from the monitoring stations.
    Code:
    http://www.dfld.de/Radar/?L=G&E=E&Lat=51.3686033&Lon=6.9400013&Z=14&FT=1#
    (it is not nice, the aircraft display is very basic, but it shows the current value of the noise stations)

    I visited the site
    Code:
    http://www.DFLD.de
    , it is naturally in German language, but this sentence caught my attention: "Der Preis ist mit 1.000.-€ Preisgeld versehen". I got it translated by Google Translate, and it said "The price is provided with 1.000 € prize money".

    I am now interested to find out how to win this prize money .

    Certainly there are opportunities to overcome technical obstacles without the need for a PC or Mac.USB is a neat connection method in hubs as well as POE but without drivers they are lost. We need to overcome that.

    Cron job to restart dump1090 and feeder - say - every hour ... but do ensure NTP sets the correct time first
    does wheezy support cron @restart (@reboot)? - some linux do, some don't

    The voltage converter is very efficient doesn't get warm at all 1A in at 12 V will probably come out at 2A+ at 5v (if that's within the device rating)

    Were coming down to the same thought - a standard component list (PI + Tuner + whatever is needed to connect to upload), and a standard software image to run it.

    That's right. I've tried today a USB-3G-dongle and the RTL-dongle on a USB-powered (1,5A) Raspberry. No chance! You need a hub. 3G feeding works fine, if you connected. My next task is autoconnecting to 3G on startup. For the feeder-sw I used the dump1090-script for autostart http://www.satsignal.eu/Radio/dump1090.html , but it will works not every time on reboot. Doesn't know why, maybe network isn't established.
    My goal is a fully operational RPI, that feed and connect automatically to my VPN after power-connect.
    You can assemble a cable-adapter to feed the hub. 2 pairs in a network-cable are not needed for 100BaseTX.

    Also

    Anyone have a bat file to start Feeding automatically when an operating system reboots on power interruption?

    Has anyone used 3g Cellular for internet for feeding?

    See post 34 in this thread http://forum.flightradar24.com/threa...and-FR24/page4 ... this will work to do the POE (the only thing I've not done is put it in a box on the mast, but POE does certainly run the whole thing and collect data using just the network cable for power in and data out) - this is to power the raspberry pi (doing the whole decoding job), the Pi powers the dongle.

    The PI starts when power is applied, and the programs to dump1090 and FR24 uploads can certainly be configured to start at boot time - My Pi does this reliably and running POE, so not theory - just not in a box.

    ----

    To do it with windows is slightly harder since you have a whole pile of other stuff to get started before you can start doing your decoding
    - first you need the PC to boot as power is applied - there may be setting in the BIOS for this,
    - then you can run the decoding & upload programs
    - - could be done as
    - - - services with 'auto' start or
    - - - fix the PC to auto logon and put the programs in the startup program group (start > All Programs > Startup)

    (Linux on the PI model B really is simpler than windows for something standalone like this - once you have got past the FUD [Fear, Uncertainty & Distrust] about using a non GUI interface ... you could even push software updates to a PI stuck up the mast)

    POE to just power a dongle doesn't make much sense - the RTL dongle is a USB device not a network device - You might use an active USB extender (I couldn't get the tuner dongle to work with one though)

    If looking to use 3G to upload - are you talking about using a 3g USB dongle plugged into the same machine that has the tuner dongle - if you are, then the whole thing will just need power (could be solar cells, storage accumulator (car battery) and a voltage regulator)

    You can run off linux - it is what I'm using on the Raspberry Pi (when it's on)

    I am a newbie here . Can I use the RTL2832U/E4000 or newer RTL2832U/R820T chip/tuner combinations with a mac computer to feed data to flight radar or only with windows.

    I'm in a similar position with a couple of poles. Putting guys on them would get in the way of people walking around. Another one would only have three sides guyed and of course the prevailing winds come from the side not guyed.
    I replaced all the poles with large diameter aluminium so hopefully there will be a lot of bend and flex but no break and snap :-)

    Rob,

    Again the angle of the pic distorts that somewhat but by the same token spot on mate. Very astute piece of observation. Unfortunately (in hindsight) where the mast was located I realised I couldnt get the guy wire anchorage on all sides far enough away from it- a very expensive lesson all round. I assumed (obviously incorrectly) that due to the extra solid mast anchorage and complying with the positioning requirements re the location of the guy wire brackets on the mast that I would overcome that limitation. 3 sets of guy wires may have helped as I noted in the post above but we'll never know. Dont tell anyone either but the distance at the base of the guy wires from each other (that is the 'triangle' formation) wasnt exactly as it should have been either. Obviously maths a physics are not my strong suits.

    I'm just very glad the antenna survived (and that no damage was done to the roof, skylights or other antennas) so that I was able to start again but do it right this time- the pro's mounted the mast on the roof ridge capping- I just bolted the 1090SJ onto the mast. I'll do a post on the new setup soon. It's decidedly better all round.

    Regards,
    Gregg

    Haven't tried a market discone for air band.
