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

    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

    • totally

      If it uses a 128-bit encryption key, which would be the equivalent of a 32-character hexadecimal password or a 40 character decimal password, you could use similar methods used to crack those. So say at a million brute force password attempts per second, if that were possible, it would only take 10 thousand million trillion years roughly to search through the entire key space once.

      Unless some fundamental flaw is found in the encryption algorithms used is found, no would be my answer.

    Hello

    I have trasteado with my RTL-SDR in my Notebook with W7 x86.
    Installed Framework 4.7.1 (before 4.6), important upadate updates, and Visual Studio c ++ 2015 (probe with 2017 as well)
    I get an error when I start the DEMODULATOR key.
    Can someone say what is happening?
    ** I tested on my Aspiere ONE notebook ** with w7 x86 and it does not give errors … it is very little hadware to support the decoding and it ends up being blocked **

    Could you please upload a video to youtube to show where to files too and from and of this working

    Cheers. Andy

    Read carefully….
    REQ0.WINDOWS XP NOT FOUND…
    REQ1.WINDOWS 7 ONLY WORK WITH SP1 INSTALLED
    REQ2. INSTALL visual c++ 2015 redistributable (BOTH VERSION! x86 and x64 – Download a install both version!)
    (a lot of hours invested in solving this!)

    • Zox

      I have both installed, but I still get this error when I click “Demodulator”
      Sender to tetra-rx – An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

      I tried using the x86 version of the plugin as well but that one wouldn’t even come up in SDR# on the left side.

    • Nope

      No, at least not until quantum computing has advanced enough to fully obsolete pretty much all of the current encryption technology in use today.

    I get this error when starting the Demodulator:
    —————————
    Sender to tetra-rx – An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)

    In this latest version there are a few drawbacks, not just positives, but of course it differs to different people:
    – Net info is not working
    – The disappearing of the polarity invert button
    – The polarity of the signal (number shown to increase / decrease frequency to get a better decoding)
    – Missing the MSYS shell window also removes the option to see what’s happening with the data, You could for example test several settings, filters, gain and small frequency adjustment to observe the effect on the decoding. ‘could not find successive burst’ is a common problem when you have a weak signal or other misconfigurations. Since there is no current way to observe any of this information, it’s a lot harder to reliably decode weak networks.

    I understand there is a diagram / signal representation but this is pretty useless whenever there is a lot of TETRA networks in close proximity of each other. Other than that, thanks a bunch

    Overall, great work to the dev! just putting out my thoughts on this
