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, but we suggest browsing to the last few posts in the forum thread to find the latest version.
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.
Hey. help me. Why is this happening?
Tetra plugin exception -System.DlINotFoundException: He yaaetca sarpysire DLL
“tetraVoiceDec”: He naiigen yrasannsit moayn. (Vcknrowene us HRESULT:
# SDRSharp.Tetra.NativeMethodstetra_ decode init)
# SDRSharp.Tetra.TetraDecoder.ctor(Control owner)
# SDRSharp.Tetra.TetraPanel.ctor(SharpControl control)
There is a bug in Tetra Plugin (I think only in last version, because in past I didn’t have this problem).
If voice channel is in “auto mode”, it stops decoding after exactly 5 seconds and “from” field turns to 0 but remains red; but if I manually set voice channel to the correct channel it doesn’t stop decoding.
At beginning I though it was somethink as “demo version” of software but I think it’s a bug.
How could I tell it to authors?
hi, when the audio comes out as a robot to call it in some way is because the communication is encrypted?

Are you investigating to decoficate tea 2? Thank you
Hi. Just to know if this plugin is meant to “pipe” Telive (Windows) to SDR#?
is thee anyway to keep the audio unmuted all the time, the audio is clipping on and off on me
Hello everybody, im new with this ,,tetra plugin”, and is work verry good but not understand that:
“””PDU encrypted:2 Data incorrect! SSI:………… Reserved26
PDU encrypted:2 Data incorrect! Carrier:….. TimeSlot:,,,,,,, SSI:…….. Reserved25
PDU encrypted:2 Data incorrect! Carrier””””
pdu encrypted:2 what it means. or how to solve it.because normaly,don t apear that pdu.
Is there any way to filter or silence the encrypted data? I have one frequency with a few different users but one is encrypted. It would be nice to un-select them as the audio is quite loud and garbled
hmpf,, cant select the proper output device, 2 sound card, always picks a SPDIF device
I have the plugin working successfully with SDR# 22.214.171.1246. Does anyone know the rules syntax for audio recording?
Same problem. Any solution?
Regards from Barcelona, Catalunya.
I have experienced an error in my windows 7 Ultimate 32 bit.
I have installed Net Framewort 4.6 and visual studio c ++ 2017.
Previously I tested with visual studio c ++ 2015 and gave the same error.
I know that the SHEHZAD user, as I was able to read the comments below, had an error in his SdrSharp.
Shehzad solved it by installing visual studio c ++ for 64 and 32 bit machines.
In my case I can only install for 32 bit, so I can guess that your problem was solved in the installation of 64.
All the steps followed and tested again and again with the same error.
I always run as administrator of my system
I have also tried plugin installations in SdrSharp from other users that work, two installations from different users and always throws the same error.
This is error:

I use both, Tetra Telive (over Ubuntu) and SDR# Tetra Plugin (on Win 10)
Tetra Telive has teh very useful way to filter exclusive ssi group, and you can “follow” de communication develope. Activating or desactivating selected ssi group. I have still some audio drops issues, but the filter and the complete activity audio record .ogg files is great.
My first impression about SDR SHARP TETRA PLUGIN is positive, the audio quality is better and easy to customize. I m looking and add to my wish list, we can RECORD THE AUDIO QE LISTENING TO (without open Audacity or similar tool) and It would be fantastic filter ON/OF SSI groups to follow full conversation. Somebody know is there is some tip or setup to add SDR PLUGINS these functions ? This plugin open a big way to learn and enjoy about fantastic radio, asdr and tetra universe.
the ssi filter is a great idea!
how do you improve the quality of the audio you receive its all bubble gum gargiling noises for me
Maybe you’re trying to listen to an encrypted station
