How To Install Libncurses Ubuntu Linux' title='How To Install Libncurses Ubuntu Linux' />Listening to TETRA Radio Channels. TETRA is a trunked radio communications system that stands for Terrestrial Trunked Radio. It is used heavily in many parts of the world, except for the USA. Recently, a software program called Tetra Live Monitor telive was released on Git. Hub. This software can be used along with the patched Osmo TETRA software to monitor and listen to unencrypted TETRA communications. Below we show a tutorial on how to listen to TETRA communications using a RTL SDR RTL2. U software defined radio. This tutorial is based heavily on the telivedoc. Please refer to that pdf file for further details on how the software works. We have modified their tutorial slightly to make it a little easier to understand. As this code is still under heavy development if you have trouble please check their PDF file for modifications to the procedures. Again, we reiterate This tutorial is not a substitute for a thorough reading of the documentation. If you have trouble setting this software up, please refer to the telive documentation first, before asking any questions. It contains a comprehensive FAQ section which solves most of the common problems. The documentation can be found directly at https github. There is also a discussion at http forums. Decoding and Listening to TETRA Tutorial. Most of this tutorial is performed in Linux and we assume that you have some decent Linux experience. I installed the latest version of Cygwin with a number of packages. I soon realised that I need more packages such as wget, etc and I couldnt find a way to install. We also assume you have some experience with the RTL SDR dongle and have a decent antenna capable of picking up TETRA signals in your area. If you dont have a RTL SDR dongle yet see our Buy RTL SDR dongles page. Note As of October 2. Windows port of the Telive decoding software available. This may be an option for you if you prefer to run in Windows. More information here. First, we will need to find some TETRA signals. The easiest way to do this is to open SDR or another program like GQRX and look for them. TETRA signals are continuously broadcasting with a bandwidth of around 2. Hz. In most European countries they can be found at 3. MHz. In some countries they may be found around 8. MHz or 9. 15 9. MHz. There may be several TETRA signals grouped in close proximity to one another. Linux kernel is the life force of all Linux family of operating systems including Ubuntu, CentOS, and Fedora.

In this tutorial we use a 3. Ubuntu 1. 4. 0. 4 virtual machine running on VMWare Player as our Linux system. Some of the commands may vary if you are using a different system. Install the software. Note There is now a telive live Linux image available. This will allow you to boot via a USB drive straight into a Linux OS with telive preinstalled. If you want the easy way out, or have trouble with the install script below, then try this image. Note 2 As of October 2. Windows port of the Telive decoding software available. This may be an option for you if you prefer to run in Windows. More information here. About Electron. Electron is an open source library developed by GitHub for building crossplatform desktop applications with HTML, CSS, and JavaScript. This install script will automatically download the software and all the required prequisites including the RTL SDR drivers. If you have problems consult the documentation or try a manual install. Instructions for the manual install are shown at the end of this post. Running the Software. Open a terminal window and browse to tetraosmo tetra sq. Open a second terminal window or tab and open a specially sized xterm window using the following. In the xterm window, browse to tetrateliveand run. Open another terminal window or tab and browse to tetrabin and run. Open another terminal window or tab and open GNU Radio Companion by typing the following. In GNU Radio open the telive1chsimplegr. Execute the flowgraph by clicking on the play button icon on GNU Radio Companion toolbar. At the bottom of the screen that pops up look for the Frequency text box and enter the centre frequency of the TETRA signal that you want to monitor. You can also click on the centre of the TETRA signal spikes in the Full Spectrum view to tune to a different signal. Enter the PPM offset of your RTL SDR dongle in the ppm text box. Finally adjust the SDR Input Gain setting for best reception. Telive Receiver Window. At this point you should confirm that you see a strong rectangular TETRA signal in the FFT window that pops up. If you do, switch back to your first terminal window where you ran. You should confirm that you see system data scrolling by. If there is no data scrolling by, try adjust the gain and PPM offset in the FFT window. If data is scrolling and the system is not encrypted you should start to hear voice audio. If a system is capable of encryption, the terminal window with the system data will show Air encryption 1. However, note that even if it shows this, there is still a possibility that encryption has not been enabled. Note that for a one channel receiver the frequency you tune to should be a control channel. The control channel frequency is the frequency shown in the top row of the Telive window in the green bar next to the word Down. By pressing t lower case T in the Telive window you can toggle between the usage identifier window and the frequency info window. By looking at the frequency info window you can find neighbour networks. Free Download Beyblade Games Metal Fusion more. If you want to log all voice communications you can by pressing shiftR upper case R in the telive window. This will log. ogg audio files to tetraout. You can also enable a text log by pressing l lower case L which will to tetralogtelive. More options can be found by entering Telive is also capable of decoding SDS messages, which are used to send short text messages or radio locations. If the TETRA system you are monitoring does send radio locations via SDS, then these can be automatically exported to a KML file which is stored at tetralogtetra. If you open examplegoogleearth. Google Earth will periodically read from tetralogtetra. You can also set the TETRAKMLINTERVAL environment variable which defines how often the location file will update. The default is 3. If you happen to close the GNU Radio FFT window and want to run the program again, you will need to restart the . To see how to monitor two or four TETRA channels simultaneously, refer to the telivedoc. PDF file. TETRA Decoding Windows. OLD MANUAL INSTRUCTIONSDont use these instructions unless you cannot use the automatic script install for some reason. Install the RTL SDR Linux Drivers. If you havent done so already, follow the instructions at http sdr. Linux RTL SDR drivers. Remember to blacklist the DVB T drivers on Linux. Install Prerequisitessudo apt get update. Note that if you use a different Linux OS, then some users have reported needing to also install the following extra dependencies sudo apt get install git core autoconf automake libtool g python dev swig libpcap. Install GNU Radio 3. The TETRA decoding software requires installation of the older GNU Radio 3. The easiest way to do this is to run Marcus Leechs install script with the o flag, to indicate that you want the old version cd. This script will run for a few hours and should install GNURadio 3.
