List of SDRSharp Plugins

There are a number of SDRSharp plugins that extend its functionality. Here is a collection of all the plugins and download links that I could find. The installation of most of these plugins will require editing the Plugins.xml file with a text editor such as notepad. Most files will contain a readme.txt or magicline.txt file that shows what line to add to the Plugins.xml file. Just copy and paste the plugin .dll into the SDR# folder and add the magicline line to the plugins.xml file to install the driver.

Note: Now that SDR# has updated to the .NET4.6 platform (October 2015), many old plugins that are not maintained may no longer work. However the actively maintained plugins have all been updated and are listed below.

Unitrunker Serial Based Trunking Plugin

Allows Unitrunker to interface with SDR#. For example it can be used to allow unitrunker to control the frequency setting in SDR# to following trunked conversations over various frequencies.

Frequency Manager + Scanner and Scanner Metrics and Frequency Entry Package Plugin

This is a plugin package which comes with three plugins. It comes with a more advanced frequency manager than the one shipped with SDRSharp.

It also has a scanner option which can quickly scan through a group of your saved frequencies, looking for an active signal.

It also has a scanner metrics plugin, which records frequency activity to a database. Later this database can be analyzed to find out which frequencies are the most active, saving you time searching manually for active frequencies.

Finally, this package also has a frequency entry plugin, which works like the old SDRSharp frequency entry used to work. Basically, it just allows you to choose a center frequency and IF frequency easily by typing it in instead of adjusting it with the mouse.

Plugins that no longer work

These plugins no longer work, but may still work with older versions of SDR#. Usually they stop working because of an SDR# upgrade that requires some minor modification to the plugin, but the plugin is no longer maintained. Some provide code so there may be hope in getting these running again if someone is willing to make the changes and recompile the code.

Orbitron Plugin (Not working with 1400+)

Allows the Orbitron satellite tracking software to control the frequency in SDRSharp. This is useful as Orbitron can automatically correct for the Doppler shift when listening to satellites.

Other Plugin Lists


  1. Bill N4DM

    SDR# v 1430 AirSpy Win10
    Is there a plugin that extends the range of “Spectrum Speed”, i.e. X10, X100 X1K? I would like to make the waterfall ~12 hours top to bottom with scaled time markers.


  2. Thomas Morgan

    I have tried these plugins but need something they do not provide or I am not setting it up right.
    I would like to scan a frequency range and log the entire list data set including Noise Floor to and database .
    lets say 400 too 700 mhz logging the signal at intervals I set. Just measure, report and log,
    If anyone thinks they can help me email me for details.

  3. Schalk Nell

    i am new to sdr but not to radio and would like to know if a plugin has been developed that can decode DTMF,ANI,ZVEI ect .Has anybody tried this or experiment with it that can help me with this .I found a program on the net ‘Wintone” but it was written for windows 95 and it looks like no more support on it

    • noname

      Man, do you understand that Windows 95 is an operating system from the year 1995 ? That is 20 years ago. Maybe you should focus your search on something more recent?

  4. DD1US

    I am searching for someone who could help me in writing a small plugin for SDR#.
    I have a network controlled antenna switch and would like to be able to switch the
    antennas out of SDR#. The first step would be to integrate some buttons to switch
    4 output signals on and off. I would be already very grateful if someone could help
    with this. Of course there are additional options like selecting the antennas automatically
    as a function of selected frequency etc, but that might be too sophisticated. Any help
    is very much appreciated.
    Kind regards
    Matthias DD1US

  5. Jim

    I would like to see a wideband spectrum analyzer application. I understand that they are limited to 2 MHz of spectrum, but take a sweep, move 2 MHz and take another, and so on. It would be slow, but usable. I’d like to be able to see 100 MHz in one sweep.

  6. CJ

    Hi all,

    Is there a plug-in to scan set frequencies? I’d like to monitor know airband freqs in my area but the only scanner plug-ins I can see are ones which monitor from (lets say) 133.500 to 143.500 not pre-defined channels such as 133.900, 145.000, 122.700, etc. I hope that makes sense.

    • adriaan

      Looks like “Frequency Manager + Scanner and Scanner Metrics and Frequency Entry Package Plugin” is what you are looking for:

      “This is a plugin package which comes with three plugins. It comes with a more advanced frequency manager than the one shipped with SDRSharp.

      It also has a scanner option which can quickly scan through a group of your saved frequencies, looking for an active signal”

      (i’m new to SDR to, just ordere my stick and was looking for the same, looking to log for about a day with fast scan of a wide range of frequencies to find interesting parts, and then let it scan with audio on the frequencies.)

  7. Perth SDR Guy

    Hi, Is there a way to use it like a scanner, enter the frequencies with different ctcss for each frequency as channels, enable or disable each freq/channel and scan through them? The individual ctcss for each freq/channel seems to be missing. Thanks in advance

  8. gerald

    hi ,I have got sdr and virtual audio cable running to to try some decoding … how do I get command prompt running on sdr software ………I have seen videoes on utube with command prompt running on the screen…look forward to your reply

  9. Terry Gaff

    Hi, I’m successfully decoding DMR voice traffic using SDR Sharp and DSD+ via VB Cable software. When the VB Cable is selected as the ‘Output’ I hear only the decoded speech that DSD+ outputs to my speakers. Is there a way that I can hear the un-decoded signal also ?
    Many thanks.

    • Marcin Kowalski


      To hear the undecoded signal from SDR# piped to VB Cable, go to Volume Mixer / Recording Devices, select VB Cable Input properties, Listen tab, check “Listen to this device” and select your speaker or headphones as playback device.


  10. Peter van Stralen

    Hi There,

    Is it possible to make a update or new plugin for the AutoTuner?
    I only can find a old version of SDR Sharp where is can not correct the AGC settings.
    For the rest the functions are fine. I love the software.

  11. Leandro

    To enable the “Level Meter Plugin” in sdr# v.1299 must add the plugin key in the file “Plugins.xml” present in the root of the program, not inside the general config file as stated today in the plugin package.

    • Danie

      The Level meter and SDR# is working but I can’t do anything, like freq, mode or change anything els on the program, the spectrum an waterfall is working.


  12. Danie

    I miss a signal strength meter plugin, must be able to calibrate and read in S units and db……..There is one but does not work in the later versions of SDR#

  13. alexander

    can someone make a plugins or dll file, to “sum up” the reception bandwidth three RTL2832 dongle so you have about 6-8MHz?
    for example, to set the desired frequency in the first dongle and dll file or plugins to the second dongle to gather F +2.5 MHz 3rd f+5 MHz ( or F+2, F+4 )
    Something like this ..

  14. James C Miller

    How do I get the SDR SHARP to display the converted Freq from the HAM UP converter?
    Is this a manual calculation Subtracting 125MGHZ from the Freq Displayed on the SDR SHARP ?

    • Tehrasha

      Under the modulation type, there is a checkbox labeled ‘Shift’ and to its right a field to enter a frequency.
      Enter -125000000 in the field and click the checkbox. SDR# will now display the shifted frequency in the HF range. The crystal on your upconverter will not be a perfect 125Mhz though. Tune to a known frequency (such as WWV on 10Mhz) and adjust the value in that field appropriately. For example, mine ended up being -125,000,580

  15. Mike

    I have downloaded the satellite tracker plugin and added the line from the readme file to the sharp plugins section of the sdrsharp.exe.config file. But when I open SDRSharp and I go to the Satellite Tracker plugin next to the Tracking Software title is an empty box. There is no dropdown to choose Orbitron from. I have uninstalled the plugin and re-installed it but it does the same thing every time. Anyone have any idea why the plugin acts that way?

    Hello, I have a Problem with unlocking locked frequencies in the Fast Scanner Plugin, when I am scanning like in this Picture: It will be better if the scanned frequencies where stored in a XML file, so after a scan I could edit this file how I like.
    The other Problem is when I am scanning and switching with skip, I could get angry If it do not swith to the next band, there should be a button in the scanner which can tell the scanner it not to Switch only the frequency, it have to Switch to the higher band I am scanning.
    Do you dudes think you can code it? – I would be very happy for this and I think not only me wanne tank you for this modification in the next Version of the fast scanner plugin! ;D

    I’m currently looking for a plugin (Autotuner) previously downloaded from this website:“; on the webiste I may still find the presentation and a link to download it. Once downloaded the file named “” (with a size of 1046 Kb), then unzipped it, I have tried to run the “SDRSharp” but it does not contain anymore
    the desired plugin (Autotuner).
    Does anyone know where I can find an Autotuner plugin?
    Thanks for your help
    73 de Sergio

    • admin

      Hi Sergio, I have tested the download and I see that the AutoTuner plugin is there and it is working. Perhaps you have missed it as by default it is minimized. Underneath the Frequency Manager you must click the [+] button next to the word AutoTuner to maximize the AutoTuner options.

  20. IN3IEX Giorgio

    I am very interested in the scope plugin.
    I develop old style AM transmitters and the scope view is very useful to see the envelope (rx in USB or LSB)
    It should be necessary to have two “speed” controls for the scope.

    1) trace speed, like ms to have a full trace, going from maximum speed to about 1 second for a full trace (to see individual words)

    2) hold off time, that is time between one plot and the following one, useful to have time to “see” the individual plot, going from the minimum possible to a full second or even more.

    Super accuracy or calibration is not necessary, so do not invent anything new, just change actual speed cotrol to these two suggested controls.

    Thank you again.

    • IN3IEX Giorgio

      After a week spent learning C# I was able to write two new oscilloscope plugins.
      The first one is the one I needed for TX monitoring, the second one is the “stereo panoramic” oscilloscope display, a rotated XY unipolar plot, similar to a plot I saw on Sequerra FM tuners.
      Both available on SDRSharp Yahoo group files section (you will need to join the group first to download).

    i purchased a dongle,,a small square dongle to get radio aircraft frequency,,but it doesnt work,,i plug into a windows and a mac,,both do not even recognize the dongle,,nothing happens,,i have a small mini disc i loaded into windows machine,,nothing in it,,nothing worked,,it doesnt work on my mac,,disc wont load on mac,,to small,,this thing is worthless or i dont know how to work it,,what do i do??how do i get this dongle to work,,it is,,dvb-t r820t 2832u dongle,,why doesnt it work,,why doesnt computer even recognize and driver loads??no driver at all,,where to get drivers and other plug in,,,?????help.

  22. Petri Toivonen

    Has anyone considered using GPU in SDR? I think that many DSP processes could benefit from using CUDA or ATI STREAM, or just OpenCL.

  23. Jeff Knapp

    Hi, just a note to say thanks for including my plugins in your list and to say thanks for updating your link to the installer. I appreciate it.
