SDR# (SDRSharp) is released under the MIT license for the GUI and the plugin parts, and under the MS-RSL for the DSP.
As such, you can:

  • Create, Modify and Redistribute plugins
  • Create, Modify and Redistribute the GUI in both its binary and source code forms under a different name (it’s no longer SDR#!) preserving the original copyrights and licenses

But you cannot:

  • Modify or Redistribute the DSP (SDRSharp.Radio.dll and its corresponding code)

Important note for RTL-SDR users
You can use this quick installation script to test the latest development version:

    Hi Youssef!

    I downloaded the new 459 version, but Windows 7 will not start.
    Trouble is: Sharp SDR operation is stopped, the windows looking for the problem.

    In the previous 451 version went perfectly.

    What has happened?

    Thank you for your answer

      I personally have never developed applications for the visually impaired. There are some constraints I should learn before doing anything.
      May be adding tooltips can help? In any case, check the download page as often as possible for new features.

    Hi Youssef.

    Excellent software full of future.
    I use essentially FC0013 because these tuners work fine 22 in 1700 Mhz without the hole between 1,1 and 1,25 Ghz.
    I noticed that SDR# does not manage any more the PLL below 33 or 34 Mhz.
    Think you be able to improve this problem of management of the FC0013 ?

    Still thank you for all this work !

    A fantastic program keep up the good work. I also get the above error on the last two dev releases when switching frequency. Do you have any sort of bug logging system ?

    A memory system so you could just fire it up and go would be great.

    Keep up the good work.

    last two development releases have a new error. When I enter new frequency, I can get one or another error (it’s ok to press continue – it keeps working).

    Would be good to mention that the .Net framework 3.5 is required. My PC has 4.0 and the program quit with a non informative message. After getting the source in C# , the compiler (VC#10 express) warned about the wrong framework. After a recompile SDR# is running fine.

    My very very big THANK YOU for developing this software. I noticed frequency correction in frontend, bravo!

    Is it possible to produce ExtIO_RTLSDR.dll suitable for use with PowerSDR and WRPlus every time you release new dll frontend for SDR#? I tried to rename dll and use in PowerSDR, but without success…
