Quick and dirty conversion of excel .csv files to SDR# frequencies.xml here.

SDR# has changed and matured since this quick start was written. Currently the best way to install SDR# is to download the installer from The install will download all the necessary files for installing and running a full installation of SDR#, plus the ADSB# and adsbhub executables.

Quickstart guides for SDR# by Youssef Touil.

The SDR# QuickStarts contain illustrations for an older version of SDR#. While the main screen design has changed, the basic information in the QuickStarts is still applicable. All appropriate updates and changes will be in the next version of the QuickStart as soon as the final (until the next revision) SDR# layout is completed.

NOTE: I’ve been asked by several people for translations of the pdf into other languages. If anyone is willing to contribute, I’d gladly post here with due attribution. I’ve been asked for French, Spanish, Italian, Swedish, Danish, and German. Of course, any language would be welcome.

    I must modify ADSB# “Decoder Confidence” value “4” to “3” but nothing …
    I post something here :

    Best regards and happy future new year 😉

  2. atouk says:

    If the dongle is on the same machine as VRS, try changing the IP to instead of using the local IP of that machine (

    The only things I can suggest is that having your antenna too close to your wi-fi hub will overload the front end noise that ADSB# will try to decode into raw hex data, and that I see you are using a dongle with an E4000 tuner. While the E4000 is a great tuner, some of them have trouble with 1090 as it’s right at the beginning of the frequency gap.

    You can try using the osmocom rtl-test to check the frequency limits of your dongle. It’s available at, in the /x32 folder.

    This is a command line tool, and the proper command will be;

    rtl-test -t

    Good day!

    Is it possible to predefine the step-values from AM NFM ….?
    For example: When I change to AM the step is always 1Khz. But I want it have fixed to
    5 Khz.

    Would be nice if you could help me, I don’t know another E-Mail, where I could ask.

    Thanx a lot.

    best regards

    I just (1/11/2012) installed SDR# on my WIN7 computer, in accordance with the process outlined in the Jan 2013 QST magtzine, using the version “Dev” – the upper left corner of the SDR screen shows SDR# v1.0.0.1110. My issue –

    The screen display on my computer does not quite match the screen shots from the magzine or your quick start guide. In particular, the frequency displays, and apparently the functions, appear to bt different. Mine shows VFO freq above the spectrum display and a Shift freq in the Radio control box. How are these supposed to be used?


  6. atouk says:

    I’ll be updating soon to include the new frequency entry system. But a quick explanation. If you click on the uppper or lower part of any digint, you increase or decrease that nuber. Also. if you place your mouse pointer over the leftmost (or any other) digit, direct keybard entry starts at that position.

    For example, if you are tuned to 350,000,000 and you wish to tune to 470,000,000, place your mouse over the 3, and enter 47, and then enter.

    Direct tuning entry can start at any position and use andy number of available digits. If the entered digits do not include the ones position, and enter will enable the new frequency. If a digit is entered at the ones position, the enter is unnecessry and the program will change frequency as the ones digit is entered. Do not use the comma while entering a frequency, as this is only used by the programto make the display easier to read.

    Drag tuning withn the FFT or Waterfall remains unchanged. Simply left click and hold your mouse, and drag either left or right as desired. You will also notice taht the “center” frequency is o longer displayed or required for frequency ently.

  7. robert kastelic says:

    The radio panel does not look like that in my copy. Its up on top and I can not figure out how to control it. When I enter a new frequency and move the mouse it dissapears(sp?). Please help.

  8. atouk says:

    Working on the new version and I should have it up soon.

    There’s a quick explanation of the tuning in a post or two above this one.

  9. robert kastelic says:

    Hey – I got it – dumb me – I was not hittin enter – Thanks.

    I could translate the guide into german. If the author is interessted I’d like to help.
    Pls contact me.

    Any translation of any document here greatly appreciated, with due credits to the translator.

    I downloaded and installed the software on my computer running Windows Vista a few days ago. I received my RTL2832U & R820T device yesterday -8/22/2013. I put it all together this AM. No problems other than a slow learning curve for a senior citizen.

    The developers of this software have done an excellent job on this software! Please pass this on to all involved

  13. Richard says:


    Do you plan to update your manual for the version of SDR#?

  14. atouk says:

    The quickstart will be updated with the next major update. SDR# has been updated and improved so much, that keeping it current with each minor change was almost a daily job.

  15. Lee says:

    Is there a Unix or Mac OSX solution?

  16. pe-jot says:

    Is there a RDS decoder integrated? How to enable it? I’ve read something related to it in the changesets of SDR# but I havn’t found anything.
    Thanks a lot!

  17. atouk says:

    RDS is built in. If there is an RDS signal in the carrier, display is automatic. However, for weaker signals, the signal to noise level may prevent it’s detection or cause erratic decoding. CPU use is so minimal that there is no On/OFF option.

    The SDR# instructions are a must and they have been well discussed and illustrated. I had been having difficulty operating it on the Windows 8.1 system, as compared to the ease of implementing it on Windows 7, but the instructions made understanding how to install and calibrate reception on my USB dongle until reading these instructions. Thanks Atouk Alunda Vita!

  20. PittyBoy says:

    Can anybody tell me, how to startup ADSBSharp together with Windowsstart, without to press that stupid Startbutton? I want to start it automaticly by Windows autostart without taking any Hands on it.
    So my question is: Is there any commandline to do so?

  23. Dominic says:

    Thank you for the converter!! Worked really well. Needed to correct the Shift field from a null to a 0. Otherwise it worked like a charm. This needed to change from “” to “0”.

    Also, on your page, you might want to include the header format of your sample CSV. It was easy enough to figure out but would save someone some time.

  24. Piter says:

    Hi! a question about the very nice ADS-B antenna: can i double (or more) all the wire length to have a better gain (dB)??


  25. atouk says:

    The antenna length is based on a 1/4 wavelength of 1090 MHz, the frequency that ADS-B signals are transmitted on.

    Changing the length will change the resonant frequency of the antenna (longer = lower). While this one is designed as a 1/4 wavelength, dipoles have also been designed for 1/2, 5/8 or full wavelength. Each one has it’s own response profile, advantages and disadvantages.

    There are countless pages and resources online for basic antenna theory from “Gee, that makes sense” to “Ooh, look! Pages of math. My brain hurts!”
