SDR# TETRA Plugin Updated: No longer requires MSYS2

Last week we posted about the release of a new TETRA decoder plugin for SDR#. The plugin made setting up a TETRA decoder significantly easier compared to previous methods, but it still required the installation and use of the MSYS2 environment on Windows. 

Thanks to reader Zlati for letting us know that the TETRA plugin has recently been updated once again and now no longer requires MSYS2 to be installed first. Now it is as easy to install as any other plugin, just drop the .dlls into the SDR# folder and add the magicline to the plugins.xml file. We tested it out and decoding worked fine. At the moment the "Net info" button is not working however.

In the future news and download lines for newer versions will probably be available on the programmers radioscanner.ru forum thread which is available here (use Google Translate to read): http://www.radioscanner.ru/forum/topic50051-9.html

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 Audio Streaming TCP Server Plugin for SDR#

Over on his site rtl-sdr.ru, Vasilli has been back at work creating new plugins for SDR#. The latest plugin is a TCP server that takes the demodulated mono audio stream from SDR# and sends it over TCP (note that the site is in Russian but the Google translate button on the right can be used). This can be used to easily stream audio over the internet or a network, or even locally on the same PC to another program. If enough programs support TCP audio streams, then the plugin could potentially replace the need for software like Virtual Audio Cable or VBCable by allowing another method for piping the audio from SDR# into a decoding program.

Installing the plugin is the same as usual. Just extract the SDRSharp.TcpServer.dll file to the SDRSharp folder, open plugins.xml with a text editor and paste in the 'magic line' specified in MagicLine.txt.

To test the server you can connect to it with VLC media player. Some special commands need to be specified to VLC in order for it to understand the audio format. To enter them go to Media->Open Network Stream and make sure 'Show more options' is checked. Enter the network URL as 'TCP://' (without quotes), and enter the Edit Options field as ':demux=rawaud :rawaud-channels=1 :rawaud-samplerate=48000 :rawaud-fourcc=s16l' (without quotes). Ensure the first colon in the line is copied over properly. Then enable the TCP server in the SDR# plugin, and click Play in VLC. Ensure the SDR# is muted, and the volume in VLC turned up. Audio should now begin streaming through TCP.

Hopefully in the future we can see some audio compression algorithms and more decoding software supporting TCP audio connections.

Vasilli has also updated many of his other plugins too, including creating a DSD_TCP plugin which allows you to transmit the digital audio directly to DSD+ via a TCP connection.

SDR# Frequency Scanner Plugin Updated

The popular frequency scanner plugin for SDR# has recently been updated (in Russian, use Google Translate). The frequency scanner plugin allows you to quickly scan through a definable slice of spectrum, stopping to listen on active signals. The new features are outlined below

1. Added the selection of multiple ranges to scan. Ranges can be different modulation and bandwidth scanning step. To select multiple ranges, use Ctrl .

2. The scanner operates completely independently of native squelch SDR #. To determine the end of the activity, a new parameter Hysteresis – is the level below which the signal is considered inactive. When using the option Use Mute , you can disable the squelch SDR #.

3. In setting the added options – choose the scanning signal with the maximum level and the width of the spectrum used.

4. Parameter Detect moved from the window in the panorama scanner settings.

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.

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.

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.
