Is there source code available for TTT and the TETRA demodulator plugin? I'm trying to make a full-system decoder based on tetra-kit and trying to understand why I'm not getting D-RELEASE or D-TX CEASED PDUs when i expect and want to compare implementations.
Thanks.
Thanks.
You can find a old source here: GitHub - vgpastor/SDR-Tetra-Plugin: Plugin to SDR# to interprete TETRA signals.
Hello,I have the programs in the following versions.
-Tetra Trunk Tracker v.1.8.9.0
-Airspy SDR# Studio V.1.0.0.1920
My AirSpy Studio have the SDRSharp.Tetra.dll on your folder.
But TTT shows the following message "Is SDR# open for CC?".
The firewall has all ports open for both programs.
Anyone help me?

I know TTT is quite limited when it comes to call recording and probably doesn’t support what I’m aiming for, but maybe someone has an idea for a workaround using an extra bit of software? Ideally, I’d like to save each call as a separate file, named using the format: DDMMYYYY_HHMMSS_GSSI_SSI. I want to ingest them into Rdio Scanner.
I have a fork of tetra-kit that does this GitHub - adryd325/tetra-kit-timeslots: OFF PLATFORM FORK OF https://gitlab.com/larryth/tetra-kit
you can edit the output format in recorder-js/call.ts getFilename()
It seems to be working well – everything that should be received is coming through. The only issue is that it’s combining individual calls into one long recording of the whole conversation. Is there a way to turn that off and save raw files as separate calls instead?
Unfortunately, I’m not too familiar with JS, so if it’s possible, would you mind sending me a modified version of `call.ts` in a private message – one that stops combining the calls and uses the filename format: DDMMYYYY_HHMMSS_GroupID_RadioID? Would really appreciate it!

Because of an instable old laptop I've switched to a new Windows11 laptop with SDR#, Tetra Plug-in and TTT. Like on the old one. Everything is working fine again but if it comes to reording the calls an error occures: " #5: The specified parameter is out of range for the specified command" and TTT doesn't record audio. Without recording I've no issues. If I start recording in TTT this error comes up, in single mode and in dual mode. I use record method #2, Virtual Audio Cable, with all settings equal to the old machine as far as I've seen. Is this error known and, more important, where to look for a solution?
I've fixed the issue with recording in TTT as mentioned earlier. I now use a really old version of VB Audio Cable. With that old version the error is gone and recording is fine now.
Can I use 2 instances of TTT on my PC, every instance with it's own Plug-in, if I change the portnumbers as stated in the documentation?

Hi all, I have the program and it's running, on an unencrypted Freq. Originally I had one SDR, and it received cntl traffic perfectly. However, I have just gotten another SDR to listen to voice. However, the only thing I hear is the tones when someone keys up.
Is there something that I'm missing to receive? VC? VC comes through fine in open ear so it's absolutely unencrypted

Probably. Read the instructions that comes with the program very carefully where it deals with audio routing.

I've read through and done everything to spec but no game. So weird...

Could it be that the SDR that you only use for the control channel have captured the voice port and left none for the voice SDR?
Set the control channel SDR to also do voice and see if that works. Do you really need two dongles? The system I'm monitoring have all the important talkgroups being announced on the voice channels and my single dongle jumps from a lower priority to a TG that I have set to a higher priority.

So weirdly I had the same problem just using one SDR however when using openear I could get voice calls from exactly the same channel...
The only thing I hear is the tx call sound from the demodulator.
It's driving me mad

It's not comming from the demodulator or the audio from the dongle. It's generated by the TTT program as a windows sound that triggers from the data info of the control channel.

I cannot find the right parameter to open TTT with a different port. I opened a second instance of SDR SHARP en opened port 3423 for TTT.
I tried the parameters below without success.
Can someone post the correct parameter please?
tetra_trunk_tracker.exe -p 3423
tetra_trunk_tracker.exe /p 3423
tetra_trunk_tracker.exe p 3423
tetra_trunk_tracker.exe port 3423
tetra_trunk_tracker.exe /port 3423
tetra_trunk_tracker.exe -port 3423
tetra_trunk_tracker.exe -P 3423
tetra_trunk_tracker.exe /P 3423
tetra_trunk_tracker.exe P 3423
tetra_trunk_tracker.exe PORT 3423
tetra_trunk_tracker.exe /PORT 3423
tetra_trunk_tracker.exe -PORT 3423
tetra_trunk_tracker.exe 3423
Thanks in advance!

Why set the port from the command line?
Open TTT and click 3 times on O, there you can set the TCP port.

It mutes the audio so you do not have to listen to the data noise or encrypted signals.
When it monitors a conversation it will unmute and go to the audio level you have sat in the TTT window.
If you conversations pop up in a little window and you still get no audio then the TCP link between TTT and #SDR are not working.
