SDR# TETRA Decoder Plugin Updated

The TETRA plugin for SDR# has been updated a few times since our last post on it back in March. The latest version can be downloaded directly here, and the original link comes from the Russian scanner forums.

In the new version the 'Net Info' button is now functioning and it is possible to see the current calls, groups, and meta information on the current cell and neighbour cell. It also appears that it has been updated to allow for multiple SDR# TETRA decoder instances to be opened simultaneously now for wider band monitoring.

    i had the same problem with crashing the program when clicking on demodulator.
    my problem was solved when i copied the libtetradec.dll to my SysWOW64 and System32 Folder

    All was ok from a long time, but today SDRSHARP crashed. I think windows update something during the night. So, I updated SDRSHARP with the last and is runing ok, but now, after add the magic line i have an XML exeception error when i launch SDRSHARP. I have the same error if i check the TETRA DEMODULATION plugin. What is the problem ?

    Clean windows 10 x64 with HackRF
    1. install zadig driver
    2. download SDR#
    3. download plugin, edit files (just as instructed).
    4.SDR# radio settings: NFM, Step Size 25kHz – it may vary in your case

      Check that your Microsoft .NET is the latest version/patch from Microsoft.
      I run 4.7.2 on my windows 10 and SDR# is very stable running the Tetra plugin.
      Another computer running Windows 7 crashed with SDR#+Tetra almost immediately after I activated the plugin
      and the solution there was to update .NET.

    O have this latest version as 06/06/18 working correctly, what is the significance of the frequency shown in blue in th plugin, is that the current voice channel, as opposed to control channel?

    • scansweden

      Seems to be the main/control channel in the Location Area, if you click on it SDR# jumps to that frequency.

    Has anybody been successful getting the recording option to work? I have not. Everything else seems to work fantastically! Thank you for your work on this.
