SDR# Plugin: FFT Window Screen Grabber

Recently Eddie MacDonald has been pumping out simple but useful plugins for SDR# including the SDR# Dark Mode and Visual Tuner Knob plugins. Recently he released a new plugin called "FFT Window Screen Grabber". This plugin simply helps you to easily take a screenshot of the FFT and waterfall displays in SDR#. It could be a useful plugin if you are constantly finding interesting signals that you want to document, or upload to sigidwiki.com.

The plugin can be downloaded from his thread in our forums.

Visual Tuner Knob Plugin for SDR#

Thank you to Eddie MacDonald for submitting his new SDR# plugin to us via our forums. Eddie's plugin is called the 'Tuner Knob Plugin', and simply enables a visual tuner knob on the screen for adjusting the frequency. This plugin could be useful especially for those running SDR# on touchscreen tablets or laptops. To install the plugin copy the .dll file to the SDR# directory and copy and paste the magicline.txt into the plugins.xml file. We tested the plugin on our PC and found it to run well.

We have uploaded the plugin here for all to download.

Eddie writes about the plugin:

Programming the plugins is not so easy considering their is very little documentation and few examples on the net. There may be a few bugs I have not caught (but i hope i have caught them all.)

This DLL was compiled and tested on a Windows 7 x64 machine and the DLL is compiled for both x86 and x64 platforms. I have tested it on SDR# Version v1.0.0.1635

I am not certain which previous versions it may or may not run on. However, being built on the 4.6 .Net framework it should work with Win7 on.

I built this plugin because i got tired of holding down buttons and waiting for the frequency changes. I figured this was a simpler method (even though some people hate rotary style controls on windows) It works exceptionally well with a touch screen.

As previously mentioned in the forum post I created the 'remote' to test my programming for future plugins for DSP

While some may not find a use for the remote I made it this way for my wife who like to cruise the dial and just see what she can pick up.

TETRA Decoder Plugin for SDR# Now Available

Back in 2016 cURLy bOi released a Windows port of the Linux based "Telive" TETRA decoder. Now the latest development in TETRA decoders is that a TETRA decoder plugin for the SDR# software has been released. This makes setting up a TETRA decoder significantly simpler than before.

The plugin doesn't seem to be officially released anywhere, but we did find it thanks to @aborgnino's tweets on Twitter, and he found it on a Russian language radio scanner forum. The plugin is available as a direct download zip from here. Installing the plugin is a little more difficult that usual, as you first need to install MSYS2 which is a compatibility layer for Linux programs. The full installation instructions are included in the README.TXT in the zip file. One clarification from us: you need to copy the files in the msys_root/usr/bin folder from the zip file into the /usr/bin folder that is in your MSYS2 installation directory. 

We tested the plugin and found it to work well without any problems. With the plugin turned on you just need to simply tune to a TETRA signal in WFM mode, and you will instantly be decoding the audio.

TETRA is a type of digital voice and trunked radio communications system that stands for “Terrestrial Trunked Radio”. It is used heavily in many parts of the world, except for the USA. If you have unencrypted TETRA signals available in your area then you  can listen in on them with an appropriate SDR like an RTL-SDR and decoder software like the aforementioned plugin.

New SDR# Audio Waterfall Plugin

The old audio waterfall plugin for SDR# seems to be no longer available for download anywhere (it may have gone out of date and is no longer compatible with the latest versions of SDR#). Alan Duffy decided to write his own version of the audio waterfall plugin and make it available for download. An audio waterfall shows the demodulated audio in waterfall form, essentially creating an audio spectrum analyzer. This can be useful for understanding the demodulated frequency structure of a signal.

To install the plugin simply download the dll from his website and place it in the SDR# folder. Note that for us Chrome detected this file as malicious, but this is a false alarm as Chrome does this often with unknown .dll files. To recover the file we had to go to the Chrome menu -> Downloads, then select “Recover File” to download the file. (If you still have problems with the download then check out the comments as some users have kindly mirrored it). Then open plugins.xml file with a text editor, and add the magicline specified on his page.

Demonstrating the IF Processor and Notch Filter Plugin in SDR#

Over on YouTube user  FMDX HUN (Luc1f3rk0) has uploaded a video showing how useful the SDR# IF Processor and Notch Filter Plugin can be when attempting to DX FM broadcast stations. He shows that it can be used to listen to stations that are almost overlapping by cutting out the unwanted signal.

The plugin itself can be downloaded from http://rtl-sdr.ru/page/para-novyh-plaginov.

New SDR# Plugin: File Player

A new plugin for SDR# has been released by Vasilli over on rtl-sdr.ru. The new plugin is called File Player and replaces the default SDR# IQ file source player (page is in Russian, use Google translate if necessary). The new features include:

  • The ability to play 32-bit WAV files up to 4GB.
  • The ability to play very large 64-bit WAV files.
  • Adds a new display that shows a compressed image of the entire waterfall and shows where in time the playback is up to.
  • Allows you to modify the waterfall play time position with the mouse.
  • Adds a stop and pause button.

Note that to install this plugin you do not add the magicline to the plugins.xml file. Instead you need to add it to the <frontendPlugins> section of the SDRSharp.exe.Config text file.

List of all SDRSharp Plugins from rtl-sdr.ru

Vasilli, an SDR# plugins programmer has released a list of all his available SDR# plugins on his website rtl-sdr.ru (in Russian, use Google translate). Some even which were missing from our own list. The ones we hadn’t seen yet were:

  1. MPX Output plugin. Allows programs like RDS Spy to work with the audio output from SDR#
  2. Aviation band 8.33 calculator. Automatically converts the current frequency input to an aviation one according to the standard 8.33 kHz channel spacing.
  3. Frequency Lock. Simply locks the frequency change settings in SDR# to prevent accidental changes.
  4. SDR Update Script. Not a plugin, but a script that automatically updates SDR# and installs most of Vasilli’s plugins all at once. To use this script, it must be placed in a subdirectory of the SDR# folder.

Here’s an example video of SDR# running the MPX plugin so that RDS Spy can be used.

New SDR# Plugin: IF Recorder

On rtl-sdr.ru, the author of several SDR# plugins has uploaded a new one called “IF Recorder”. This plugin allows you to easily record an IQ file of just the intermediate frequency (IF). In SDR#, the IF is the shaded area with the red line which you use to tune with.

This plugin looks to be great for recording example IQ samples of signals because the output file will be significantly smaller and more manageable compared to recording the entire bandwidth. It is also useful for recording IQ files for use in decoding METEOR M2 weather satellite images, as the decoding software requires an IQ file of the LRPT signal. The plugin also has a schedule option which could be used to start and stop recording the METEOR M2 weather satellite signals automatically.
