Wintelive: Tutorial and Updates to the Windows Telive TETRA Decoder Implementation

Earlier this month we posted about “cURLy bOi”’s release of his Windows port of telive. Telive is a popular TETRA decoder created by SQ5BPF which until recently only ran on Linux systems. TETRA is a digital voice radio system used in many countries other than the USA.

Now cURLy bOi has just updated his software adding new Windows GUI features and simplifying the install process. The software and text install instructions can be downloaded from his web server, and the code can be found on GitHub.

In order to show the new features and how to use the software cURLy bOi has also created a tutorial video up on YouTube, which is shown below.

    Hi guys.

    I just downloaded Visual Studio 2015 Community Edition and made some changes in the code.
    I am not into C# (I am into Java) so it is a quick and dirty hack to get rid of this int16 error,
    the wav recording is disabled now and it is possible to close the SDS window without a crash.

    Since this is not a real fix of the int16 error you probably will get some errors with frequencies
    above 1GHz added to the frequeny list while listening. Never tried if this is working correctly now.
    I can tune to this frequencies but i never see any signals there.

    The problem with the stumbeling voice (multiply channels playing the same time) still exists and the
    scanner still sometimes have probs to find any frequencies. It also seems that the code verson in github
    is an older one. The option to change stepsize for scanning is gone. Maybe I can fix it in the future
    if I find more free time.

    Anyway I only was able to compile it with debug options so the exe file is a little bit bigger in size
    than the original. Everytime I used the realease option I got dll errors while starting the prog but I
    didn’t found the source for this dlls so I can’t try a complete new compile.

    Get it here: http://s000.tinyupload.com/?file_id=82874511767130783086

    A precompiled exe and the changed source code is in the zipfile. Make a copy of the original wintelive.exe
    and then copy the new one into your wintelive directory.

    If you have doubts to start the exe just grab a copy of Visual Studio 2015 Community Edition (it’s free)
    and compile it by yourself.

    Have fun … Holger

      the problem stumbeling voice should depend on the parameter “mutessi” whose active command removes this effect
      It is what I understand by using telive in Linux System
      If you can intervene in this would be welcome
      Thanks for the work on the routine

    Hello,

    I encounter the following error when opening wintelive_10channels.grc would you have a solution?

      @cordialy
      Have the same problem.
      You should switch sdt-rtl files from another version and copy into gnu.
      If you play with SDR – sharp you have working ones.
      It is posssible to solve your problem.

    nstalled all at the start of Win Telive get the following error message nuhaded excpetio ……… Unable load DLL libtetradec dll not found hresult form 0x8007007e
    I thank those who can give help thanks

    Hi

    Someone might be able to help?

    Everything seems to work, but GRC cant enable device:
    “usb_open error -12”
    “fatal: failed to open rtlsdr device”

    But I can use SDR# without problems. Seems to be located to Gnuradio issue

    Thanks

    Hi everybody,
    I have a problem. Gnu radio, mssys, and wintelive works fine.
    The receivers tunes the signal, in discovered frequencies I se the signal but when I press Tune New and the receivers tunes the signal in Usage Identifiers don’t appears nothing.

    Where is the problem?
    Ciao!

  6. phil (correction)

    sorry this is a correction got the classes thr wrong order

    class 3 (encrypted) = No sds messages but get encrypted voice
    class 2 (encrypted) = No sds messages and No voice just 64k wav files
    class 1 (unencrypted) = No sds messages but Clear voice

    • Maurizio

      hello Phil
      I want to understand this project some things that escape me and I try to ask you
      the “gurgling” continuous “that generates the wintelive software you can ‘eliminate because it generates wav files also mostly empty and you can not delete the recording from being generated?
      The messages do not receive them, but this fact of the voice that is not encrypted transmission but overlaps
      idea?

      • phil

        hi Maurizio
        i know what you mean about the gurgling when 2 or more voice channels are transmitting. in cURLy bOi”’s video he says that in later versions he will enable us to just listen to one voice at a time. but we have not heard anything from cURLy bOi ??? disabling the saving of voice files would be great. i beleave it as something to do with the script files receiver1udp and murec but we dont seem to be able to contact cURLy bOi and seen no activity on his github or webserver so looks like things have come to a halt

        • maurizio

          hi
          thanks for the reply
          perhaps the project is dead so
          I did several tests with “receiver1udp” and ./rxx files but after a few minutes of receiving an abortion with a series of errors
          Linux Mint works perfectly but does not have the interface of “wintelive”
          Maybe the author looks to read these messages bohh
          Greetings and Merry Christmas
          I always read this blog and if there is

  7. phil

    i see we still haven’t had any updates to wintelive ?
    and still having some trouble as listed below

    class 1 (encrypted) = No sds messages but get encrypted voice
    class 2 (encrypted) = No sds messages and No voice just 64k wav files
    class 3 (unencrypted) = No sds messages but Clear voice
    still have to enter frequencys manually as wintelive wont lock on to signals in scan. tryed different bandwidths and still wont lock. also looked at murec script to try and see why i get no sds messages and to see if i can turn off the saving of wav files with NO luck
