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.

With modern SDR# installing a plugin is usually a simple matter of copying the plugin files to a subfolder within the SDR# Plugins folder. SDR# should automatically recognize the plugins.

Some plugins might require editing the Plugins.xml file with a text editor such as notepad. These plugins 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.

We note that SDRSharp can now be downloaded with a community plugin package, which includes many of the plugins listed below. However, sometimes some plugins get broken with newer SDR# versions, so if you have issues with the SDR# community edition, it may be wise to download the vanilla edition and install plugins manually.

Frequency Manager + Scanner and Scanner Metrics and Frequency Entry Package

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.

Frequency Manager + Scanner Plugin

Fast Scanner

Similar to the Frequency Manager and scanner plugin in that it automatically tunes to active signals above a certain power.

I want to use to make new databases for my rtl-sdr, how do i make my own custom made databases, please?

Neil Mudford

I presume you are wanting to cut and paste the returned listing and convert it to a SDR# frequency file?

Assuming you are using Windows and have Excel, you cut and paste the file into a new worksheet and using the provided SDR frequency file as a template, extract the data into a new list.

In (very) simple terms, once you have pasted the data and within Excel, press to open the VBA tool and create a new module to hold your code to output in the required format.

You need to press the ALT and F11 keys to access the VBA tool.

Hi experts,

I want to use the schedule for this baseband recorder.
I have set the times I need the recording.
It seems not to work.
Do I initiate the recording first before I start the schedule or what is the process.
I cannot minimize the schedule panel too to start recording when I draw the schedule
How is it used?
I want to record IQ at specific times at same frequency.

Thank You

Tom Gibson

Think you might be better off with rtl_power function from the Linux terminal with a crontab to schedule the events.


I’d like to propose a more “generic” type of plugin with only a few HW-related limits: e.g. 16 or 24 bit samples, 100Msps sample rate maximum. As of now I see that most HW-related dlls (hackRF, RTL-SDR) are limited on their input and output interface: usb and transfer to the next dll (e.g. 8bit samples, 3.2Msps max for rtl-sdr and 8bit samples, 20Msps for hackRF).

What do think about a #define line or function that SDR# can call to retrieve details about maximums instead of hard-coded limits. I.e. the HW-related dll would define the limits according to the HW it links to. E.g. rtl-sdr: 3.2Msps, 8bits and in case there’s a … let’s say … similar chip which could do 8Msps the dll could be updated and re-compiled instead of re-compiling the complete chain to get the 8Msps into the GUI. I think this could give us a more uniform interface to SDR#.

As an alternative, is there something like this related to TCP? If so I could connect to localhost:1234 and provide the details about the HW using the TCP server…

Does that make sense to you?

Hello admin,

like many other people these days, I stepped up from an RTL dongle to the SDRplay RSP. As you may know, the RSP is not compatible with SDR# builds newer than 1361, which is a major letdown for many RSP owners. Some of the greatest SDR# plug-ins have been updated to work in newer versions and the older versions still compatible with SDR#1361 are not available anymore, all the links lead to the (for us) incompatible new versions. :`(

These older versions are probably floating around on their author’s harddisks though and I was thinking a post on this prominent blog, asking the plug-in authors for making the old versions available again for us poor RSP users would be a great way to spread the word? I’m sure any SDR# user who has an RSP would appreciate that.

Thank you in advance for considering this.

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.


Bob K

is there a plug in that will allow you to have the channel names shown on the tuner area above the waterfall?


“Frequency Manager” plug will let you same stations found with a name showing in the waterfall

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.


The standalone “spektrum” program can show across a large slice of spectrum (larger than RTL-SDR bandwidth). Unfortunately no data export function, but you could screen shot the plot.

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


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?


I’m sure he knows that…that’s why he asked if there was somthing more up to date….

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

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.

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.


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.


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”

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.

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.


It’s never gonna happen. Sorry.


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.


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.



I did add the key to the “Plugins.xml” but then everything stop working……



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#

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 ?


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


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 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.

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).

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