TETRA Control Channel Decoding

[RadioDitch]

Are there any programs available which can reliably decode TETRA control channel data? There's a couple systems I'd like to work on getting into the database.

SDR# - TETRA Demodulator Trunk Tracking Demonstration

I've been messing around with SDR# TETRA Demodulator plug-in to see what I could come up with in regards to trunk tracking TETRA. I did this as a stop gap until the big players have come up with something. And in true SDR form, here is the setup. I used 2 instances of SDR# (for CC and VC)...

Thanks. The spoonfeed comment was impolite and beyond unnecessary though. Additionally, my question was specifically regarding reliable decoding of site and system information. I've experienced issues obtaining such data with those programs.

RadioDitch,
On internet a linux version floating around that possible do what others not do.

Vasilli has recently released the SDR# TETRA plugin on his website RTL-SDR.RU (note that the site is in Russian, but can be translated with the Google Translate option in the top right of the page). Previously it was only available via ever changing forum links, so it's good to see that it has a...

TETRA Decoding on Windows with Telive

TETRA is a type of digital voice and trunked radio communications system that stands for “Terrestrial Trunked Radio”. It is used heavily in many parts of the world, except for the USA. Telive is a decoder for TETRA which is compatible with RTL-SDR dongles, and has been around and in use for...

Both will show most of the useful channel information I'd expect you would need.

To my knowledge many people use TTT and the SDR# plug-in with success. Even just using the plug-in with success.
What "experienced issues obtaining such data" do you refer to? Only with feedback can something be improved.

The plug-in I have modified (to work with TTT) decodes just about everything from the physical layer to layer 2/3 protocols (MAC, LLC, MLE, SNDCP, CCME, MM and audio) as well as showing the activity of encrypted traffic to some extent, I don't think any of the other TETRA decoders does this.

Any chance you might share your modified plug-in?

Already have, it can be found in the link provided above by slicerwizard.
Download link for latest version is normal provided in one of my posts.

Thank you!

There is a linux version only show all channel traffic data, without voice decoding.
