There is a bug in the latest version ( that effects some users.

To Recap:
They ran SDR#+plug-in and TTT then clicked 'Start' in TTT, it set-up SDR# and then TTT retrieved the MCC/MNC/LA then did not continue processing any calls.

You can see more about and a workaround here:

NOTE: This has been fixed for next release.

15th Public Release - TETRA Trunk Tracker and TETRA Demodulator plug-in - v1.0.15.9

This package (version) of TETRA Trunk Tracker and TETRA Demodulator plug-in (with codec libtetradec.dll) are only meant to be used
with each other and with no other previous versions. To do so will most likely cause issues.

No changes to TETRA Demodulator plug-in in this release.

If SDR# is crashing when 'Demodulator' is enabled, it's because you have not set-up the plug-in correctly.
You MUST do this 1st. This is NOT TETRA Trunk Trackers fault.

You generally need to get these installed:
"Microsoft .NET Framework 4.6.2 (Offline Installer)"
"Microsoft .NET Framework 4.7.2 (Offline Installer)"
"Microsoft Visual C++ 2015 Redistributable" and install both 32/64 bit versions (if you use 64 bit OS)

This should fix the issue as reported here

This TETRA Trunk Tracker version changes/adds and fixes some items:

Code: Select all

v1.0.15.9 - Minor update

FIXED: String handling issue that affected some causing TTT not to start in non-English locales

FIXED: On 2nd start (after initial set-up) a pop-up error "LRRP path is not valid" would show when path
 field was left blank. Blank is valid (saves LRRP to TTT folder). The error should only show if set 
 path no longer exists.
Has been tested on Windows 7 - Basic (64 bit)
Has been tested on Windows 7 - Professional SP1 (32 bit), English
Has been tested on Windows 10 - Professional (64 bit)

I have created it to suit my needs. And it currently works for me with the TETRA network I monitor.

I make no claim that it will work for other networks.

Please read the provided files for set-up and usage:
  • TTT_set-up_manual.pdf
  • TTT_Features_and_Usage.pdf

I have tried to be as thorough as possible with the documentation to explain usage and features.
I believe any questions can be answered by reading these files.
These files most likely are not complete and contain errors and are not laid out as good as they could be.

The TETRA plug-in is now been mainly tested with SDR# 1700 on Windows 7 Professional 32 bit with no issues seen.
The TETRA plug-in with SDR# 1700 on Windows 7-10 64 bit PCs is untested by me and is known.

It only works with the provided TETRA plug-in supplied in zip. (2019-May-10).
This version uses a custom compiled version of 'Net Remote' supplied in zip

It is only meant to be a temporary solution until something better comes along.

Note: This link now is to a folder that stores the download, which means the link to the location of the files will stay the same but the files in it can vary.
