    Virtuelradar Server,.

    May I remind all using VRS to enter your own location (Lon. Lat.)
    Otherwise from your Link,. It shows South England.
    And not your location.

    Happy Hunting David

    Hello Greg!

    It's tripod from China's telescope
    I already have mounted stones to legs, only tornado can turn it over.
    Antenna mount is good idea, I have a one piece in my garage.
    When I'll get better adbs antenna then I use this mount.

    In background you can see BTS tower. Tower is fenced with barbed wire

    When I improve the results I'll let you know.

    Greetings form Poland

    G'Day Radek.
    Congrats on your successful install. Great to see the range you are getting with mini antenna.

    Now if only you could install this on the Microwave tower I see in one of your pics - in the middle of the night of course ;-)

    Tip:
    I used to have a tripod like that, with my telescope mounted on top. One night one of the legs collapsed, sending my scope crashing on to a concrete / tiled floor, causing considerable damage (to the scope of course!)
    So... BE CAREFUL !

    Also:
    If you have any roof space available under the tiles, you could try mounting your PC etc there instead of wrapped in a plastic bag (which will deteriorate in the sun).
    A bargeboard TV mount should work for you. I have 2 of them for my setup (2 different adsb antennas).
    See:http://www.jaycar.com.au/ShowLargeph...20Mount&IMAGE=

    Good luck with your project.

    Regards, Greg.

    Finally I got BaseStation signal. PlanePlotter transforming AVR signal from rtl_adsb app. I got sharekey in FR24 app.

    But I have more interesting info!
    When I put DVB-T Dongle (R820T) on roof with kit DVB-T antenna I can see planes from 250 kilometers, I can see about 20 planes in one moment. It's only kit antenna. Cost of dongle is 10 euro

    It's hard for me to imagine what happens when I plug in a dedicated 1090mhz antenna.

    I attach a few photos

    Now I fight with planeplotter but it doesn't want to catch the AVR signal by tcpip.

    Hi Radek

    I got my dongle in the post yesterday and discovered this amazing set of instructions to use Virtual Radar to feed Planeplotter and FR24
    http://sonicgoose.com/using-a-rtlsdr-dongle-for-ads-b/

    Unfortunately from my location at the very bottom on New Zealand I seldom get the required minimum 3 flights in range at once to establish a feed to FR24. However, I've ordered a 3m USB extension cable which will allow me to temporarily locate the mini aerial on the apex of my roof. Eventually I hope to build my own weatherproof outdoor antenna.

    Hello again!

    Thank you Eduardo.

    I found another great solution ----> rtl_adsb

    It is server of adsb signal, but AVR, VirtualRadar working great with rtl_adsb and display more planes than modes_rx, I can see planes in the distance 120km with kit DVB-T antenna indoor
    But how to connect AVR signal with FR24 app?

    Now I fight with planeplotter but it doesn't want to catch the AVR signal by tcpip.

    Radek,
    you may try to use an amplified USB extension cable all the way up to the roof and install RTL there, it worked up to 15 meters for me, although must protect from rain/water some how.

    Regards,

    Eduardo.

    Hello!

    I bought RTL dongle with chipset R820T.
    Dongle working well. During testing this dongle with kit DVB-T antenna I saw planes in the distance 60-70km. Antenna was indoor. I want to use better antenna.

    I thinking about make a little server on roof, because I don't want to store my PC on roof.

    I have a Raspberry Pi (a little arm computer), I have already compiled gnuradio, gr-air-modes, but.... Raspberry have to small computing power and gr-air-modes (modes_rx) not working. I saw "ooooo" messages and this means that I have too slow processor.

    However, chances are big to run it.

    Gnuradio have a great app called rtl_tcp
    I can make server that hosting undecoded radio waves.

    I tested it with SDRSharp and works great, it's need only 4mbit link.

    So I need windows or linux client which can receive radio waves by tcpip and decode adb-s signal like (gr-air-modes - modes_rx).

    Does anyone know the method to be able to decode the signal adbs from radio stream received by tcpip?

    Sorry for my english, I'm from Poland and my native language is polish.

    Best Regards
    Radek

    Greg,

    Read this page carefully:
    http://rtlsdr.org/softwarewindows

    You need to run Zadig on the RTLSDR device and update it's driver.
    Sometimes this is needed several times when you connect more than one rtlsdr, or change ports. This differs per system. Read the page.

    ppm is part of the configure as used in many programs, to correct the frequency offset of the dongle.
    Two examples:
    http://x264.nl/dump/r820t.jpg
    http://x264.nl/dump/e4000.jpg

    (This post may seems redundant, but i forgot to press Post Quick Reply ...)

    Hi Greg, I suggest you install SDRSharp from the following, it will run a .bat script and put all the necessary files in the correct location:
    http://sdrsharp.com/downloads/sdr-install.zip

    After installing follow the instructions here:
    http://rtlsdr.org/softwarewindows

    I hope it helps you.

    Eduardo.

    RTL-2832u / E4000
    ADBSScope v2.6
    ADSBSharp
    FR24feeder

    Some tips:
    0. After RTL-2832u driver installed correctly using Zadig.exe
    1. Run SDRSharp and look for some reference signal (ie a vhf/uhf beacon or narrow band FM signal) to determine the necessary frequency correction (ppm) - my case it is 18
    2. Run ADSBSharp inserting the verified ppm correction, unchecked RTL AGC and Tuner AGC, leave RF Gain in the max and start.
    3. Check if there are frames being received.
    4. Run ADSBScope go to other > network > network setup. Leave port 30003 on server and click on ADSB# for raw data client. Start raw data client and start server.
    5. Start FR24feed

    Regards,

    Eduardo
    G'Day Eduardo.
    I've tried a similar system here, but it isn't working.
    Problems:
    1. I can't verify that Zadig is actually installed / running. (There does not appear to be anything called zadig visible using MS Services). Do you know what the service is called ?
    2. SDRSharp is not picking up anything. And I don't understand your comment re frequency correction (ppm).

    Thanks, Greg.

    I am using a RTL-2832u-R820t USB dongle, zadig driver, RTL1090, Planeplotter and FR24feed. All working fine at my location (Tallahassee, Florida, USA). Just have limited receive due to the small vertical antenna that came with dongle. I am getting good coverage up to about 40 nm and sketchy coverage out to 50 nm.

    I am using a 2 meter USB extension cable to get the dongle close to a window and the small antenna is just outside the window. I am awaiting shipment of additional parts to use a better antenna mounted higher.

    This is all Windows-based software.

    Hi GregHudson

    I started on ADS-B in 2007 with SBS-1, then followed with RadarBox.... did several antennas ... including two 21 stacked dipoles coax colinear....
    Since one week started to play around with ISDB-T dongles and become astonished with the results.
    Also noticed that for me it did not worked using a 10 dipole collinear coaxial..... but I a getting eazy 180 NM with the dongle original antenna
    modifyed to clone the whip of the radarbox supplied aatenna and let it on the window... (ok , I live on 15 floor ..)
    Still doing tests ... with one E400 and one R820T... several antennas, several softwares ....
    I found these dongles cheap and marvelous for playing around.


    Cheers - Juan -
