    I have the same problem with the newest 2013 adsbox version on my RPi, but the previous version (2012 something) works quite good.

    Hi everyone!

    Here is my testing report of RTL8232 820t DVB-T USB dongle+ original antenna supplied with stick and 1090 software + Plane plotter trial . Antenna mounted on the car roof. It was very funny finding ads-b signals on the spring day in northwest part of Bosnia and Herzegovina .

    drina_pd, try using ADSB# it picks up even fainter signals and therefor you get a longer range. Today i broke my own record as well:

    You can grab adsb# from here: http://sdrsharp.com/index.php/downloads

    RTLSDR mini ( http://x264.nl/dump/rtlsdr_big-mini.jpg bottom one ) + ADSB# ( http://sdrsharp.com/downloads/adsbsharp.zip ) + a proper antenna ( mine http://x264.nl/dump/ads-b-antenna-gr...ane-proper.jpg ) = seems to give the best results. Other testers have also confirmed these findings .... http://www.rtl-sdr.com/adsb-aircraft...-with-rtl-sdr/

    Thanks Jarod!

    Good work! You have really wide range.
    Today we have local HAM radio FM contest and i will make some test with ADSB# which you recommend and J-pole antenna from new contest location. I saw now trough my windows that weather is pretty stormy and it is really dangerous to be on the top of the Mountain . I will post new pictures here after all test would be completed.

    We have now published a guide how to setup a DVB-T USB-stick with FR24

    We have some extra DVB-T sticks (including antenna) in the office that we'll send out for free to the first 50 applications we get from locations where we currently don't have coverage (check map on Flightradar24.com).

    Why on earth would you recommend rtl1090?
    ADSB# has much better reception and runs much simpler. (Also a lot of code has been "borrowed" from ADSB# as it's open source. Still the DSP is much better than rtl1090.
    You can simply test yourself. But the true colours or commercialism always are shown when it comes to money, so one could only guess why a lesser product is endorsed instead of testing and using the best.

    I am picking up much more planes on the ground from Amsterdam Schiphol (EHAM) then those professional tuners.
    Or my location is just very good, or this setup is working very well.

    Edit:
    Never mind on the not promoting adsb# .... they of course have their own hub which could be considered "competition" for FL24. (However i know it's creator wouldn't mind FL24 linking up to that hub.)
    If FL24 and it's members are truly interested in having the best reception, it might be possible a none hub function could be made especially for FL24.
    I would have to ask it's creator.... but only if you guys are interested...

    If you need help installing, come to irc.freenode.net and join #sdrsharp
    And we'll fix you up with adsb# sharp as well...
    And if the guys from FL24 had done a little more research and/or read my forum posts they would have found out that the R820T is MUCH better than the E4000 tuner for ADS-B.
    And.... that the RTLSDR R820T mini even more better working than the big version.
    http://x264.nl/dump/rtlsdr_big-mini.jpg (bottom one)
    The mini has a lower noise floor and much less spikes.... 1090MHz reception skyrocketed with the mini.
    Compare: http://x264.nl/dump/rtlsdr-r820t-big-sdrsharp.jpg vs http://x264.nl/dump/rtlsdr-r820t-mini-sdrsharp.jpg

    And then there is the antenna, you can buy a "ADS-B" antenna for nearly 200 EURO (which is just a piece of coax cable) or you can actually do some testing and find out a proper GP works so much better.
    Like so: http://x264.nl/dump/ads-b-antenna-gr...ane-proper.jpg

    But let's have the results speak for themselfs: http://x264.nl/dump/rtlsdr-mini-virt...1.1-record.jpg (yes this is my reception, all planes on the map are from my setup)

    Let me add some valid ebay links as well:

    $12,66
    http://www.ebay.com/itm/USB-2-0-DVB-...item337f93cc26
    http://www.ebay.com/itm/New-USB-2-0-...item337f34b0be

    $12.86
    http://www.ebay.com/itm/New-USB-2-0-...item337f151ebb

    Don't have the numbers fool you, they have thousands, they change price depending on how much are sold.
    $12.66 has been a fixed price for months now, as they still keep selling, they started out as low as $10.

    Sometimes there are multiple sellers as well, myflash168 and gbox_au are two good sellers..... however all rtlsdrs i ordered came from the same warehouse in Hong Kong.
