Decoding a TETRA voice signal is as simple as opening the program, tuning to the TETRA frequency and clicking on the signal.

Tetra consists of two complementary standards: A standard Time Division Multiple Access (TDMA) cellular communication system for voice and data communication on 25-kHz channels.

If you want to log all voice communications you can by pressing "shift+R" (upper case R) in the telive window. Did you find any solution to this? Save my name, email, and website in this browser for the next time I comment.

The decoder implements a soft synchronizer allowing missing frames (50 bursts) before loosing synchronization. - solved center frequency issue (DC problem)

WebTETRA Trunk Tracker reads DATA that is output from the SDR# plug-in TETRA Demodulator (by TSSDR) via the 'Network Info' calls log window. Imagine the possibilities.

You can, of course, get commercial equipment to monitor these radios, too, but what fun is that?

Yippi!

I had the same error. That is in use today and it encrypts communication. if its encrypted then you cant listen to it with this software.

With good signal strength voice comes through very clearly. SECURE. WebTETRA radio system supports semi duplex operations for group communication.

TETRA is a RF digital voice and text communications protocol often used by authorities in European and other countries due to its ability to be secured via encryption. File /usr/local/lib/python2.7/dist-packages/osmosdr/osmosdr_swig.py, line 28, in Finaly found the time to install it and test it (using the install script) and for most part it went well.

Sometimes it'll pick up a full transmission. (Not overloaded CPU usage.) TETRA is a type of digital voice and trunked radio communications system that stands for Terrestrial Trunked Radio.

The changelog reads: 6/4/2020 Back in May 2016 we posted about Dejan Ornig, a then 26 year old student at the University of Maribor's Faculty of Criminal Justice, Slovenia who was almost imprisoned for using an RTL-SDR and finding a security flaw in Police TETRA communications. And 2nd release for (TETRA Trunk Tracker v0.99.6s - Simple)

The TETRA plug-in currently been developed by TSSDR is also in early development. Worked for me. TETRA radio uses /4 DQPSK modulation scheme.

(question mark). Just found out a solution to this problem.

It is used heavily in many parts of the world, except for the USA. It interprets this DATA to determine when a call is set-up, then instructs SDR# (VC) to move to the carrier (frequency) that the call will be on. A physical layer transforming PI/4 DQPSK rf signal to bits (RF frontend is NESDR at 2MBPS), A decoder, which is the actual TETRA stack reading bits and transforming it to Json text, A recorder, which read Json stack output and reorder speech frames into separate files. Programmed and wrote software for the CCII & +/Embassy.

fixed-working now once i plug in the dongle just before launching the play button. A small USB receiver, such as a Funcube dongle, can be inserted into a notebook, and software, like the OsmocomTETRA presented by Welte, could then be used by anyone to receive and listen to the TETRA radio communications of utilities and public transport providers. Larry writes: [TETRA-Kit] is inspired by a lot of existing stuff (see 'Previous work' in the project page) but started from scratch with those following ideas: The decoder implements a soft synchronizer allowing missing frames (50 bursts) before loosing synchronization. Listen to this page.

What is the process you followed? Everything ok, but when I run gnuradio this is the error message: If the TETRA Demodulator does not work for you this program will do nothing to change that. Starting the receiver1 1 creates the following error : Traceback (most recent call last):

Finally adjust the SDR Input Gain setting for best reception.

Then ive seen something like this on every tetra cahnnel over here both fields are equal to 1

Then delete "Tetra-trunk-tracker.dat" as it has changed and old one will cause error on load. Lee was a crazy site! I continued to test and experiment, with no luck. The amount of filler on this site is getting rather excessive. It is only meant to be a temporary solution until something better comes along.

Mael Dorne has updated details to Garden Defender. The latest version currently supports the decoding of FM/AM, TETRA, DMR, Pocsag and ADS-B. WebDigital data transmission is also included in the standard though at a low data rate. Unzip the file, making sure to unzip with lower case letters by using the following unzip command.
