OP25 is a program that decodes P25 Phase 1 and Phase 2 digital radio. Some municipal areas are upgrading to P25 Phase 2 so almost gone are the days that you can track them with a police scanner since P25 is a Trunked Radio system and not just a thermo king apu compressor frequency to monitor. The only things that do Phase 2 are hardware scanners and hardware radios and OP25 for software radios.

Bear in mind Phase 2 could be encrypted and nothing you can do will decode it. There are tutorials out there, some good but everybody leaves out the good stuff or the stuff they took for granted.

In a pinch I guess the first thing you could do is to install gqrx which would pull in all the necessary RTL stuff you need. Follow the directions here if you need to. Download from the repository using this command. But you only need one of these to track a trunked radio system. Lets find the trunked system to follow. This page will not always be spot on. Letter of interest for teaching position actual control channel at the moment they change it sometimes is It will sound like digital noise.

And the signal will be a constant spike. As you can see I found my Control Channel at You may also have to adjust the -2 number depending on your individual SDR. Have fun with that. You just have to play around until you get your signal centered on the plot. As per the pic below ………If where it says Keep messing with the q number until the signal is centered on the plot. Something like the box above should pop up. Copy your NAC for your frequency. Now you should still be in the apps directory.

Double click on the file named trunk. Make sure the file looks like this and has these settings. Now take note of the way I changed the file. Save this and exit. Now open the file tompkins. Make sure the settings are the same as depicted above.This page contains links and downloads for utilities that can be used to decode the data streams of various trunked systems.

Many, though not all, of these applications require audio from the Discriminator output of your scanner. Some of the older utilities like Trunker require you to convert the audio from your scanner into serial data by using one of the circuits or pre made units shown on the Data Slicers page.

See the applications' page for more information. If you have questions about these utilities, please post on the Voice Control Channel Decoding Software forum. Description: The E-Trunker Utility. Note this is a DOS application, but is compiled to only run under Windows. This is the latest beta release RC4. Some modifications to the discriminator input are necessary to add additional filtering for using this utility. The schematic for these changes is shown here.

This program served as a proof of concept for using a sound card instead of a serial port for input. Persons so inclined may wish to compile this into an executable using Visual Studio 6 or Visual Studio. This example runs in console mode and displays talk group information as it is decoded from the microphone input of the soundcard. And now supports converting a hex or decimal number to Uniden AFS.

You can calculate a base frequency for each allowable offset, print out a full range with a given base and offset, convert a channel hex id to an or frequency, and define a configuration for programming a Motorola radio or system.

OP25 is a not-for-profit project to bring together folks that are interested in implementing APCO P25 using a software-defined radio. APCO Project 25 is the digital communications standard used by many police and emergency services throughout the world.

Compared to existing analogue systems P25 offers improved spectrum use, coverage and flexibility. Provision is made to ensure the confidentiality of traffic, to allow the use of trunking and the provision of data in addition to voice services. For example, software radio approaches can receive many channels at once, handle both voice and data including the trunking control channeldecrypt encrypted traffic when the key is known and log traffic to disk for later analysis.

With the right software an SDR is a powerful analysis tool for debugging and monitoring of P25 networks. That's the sales message. The reality is software-defined radio isn't yet as simple as the plug-and-play of hardware radios. You will need a lot of patience and a fair amount of software skills to get working. To get an idea of the work involved you can check out Hardware for your software radio by Stephen Cass. In that sense this really is an amateur radio project and requires the same kind of skill and dedication but we've a few people who will help out if you run into trouble.

A project like this needs many different skills so even if you're not technical you maybe able to help in other ways. As all Wiki pages, this page is editable so these ideas are not fixed in stone. Developers can simply click on the "Edit this page" link at the bottom of the page although it is worth familiarizing oneself with Wiki formatting beforehand. Please realise that this is developmental software and it does take a fair degree of skill and understanding of hardware and software development under Linux to get it working.

The mailing list opdev is there to help people that try to help themselves.

No need to implement this as there are plenty of other solutions out there already that are quite good.

Hardware -- The recommended hardware for this project. Software -- An overview of the project software. Patching WireShark -- Patches to!Digital Speech Decoder is an open source software package that decodes several digital speech formats.

It uses the mbelib library a separate open source package to synthesize the decoded digital speech. It does not allow decoding of encrypted communications. It can save the compressed digital audio bits to "mbe" data files. It's discussed in this forum. Any linux distribution should work as long as it has support for your audio devices.

DSD version 1. The forum for discussion of this package can be found here. This means that as far as copyrights are concerned it can be freely copied and used, including for commercial products as long as the original copyright notice is included. However, see important patent issues section below. While DSD was intended to be patent-free, mbelib describes functions that may be covered by one or more U.

The source code itself should not be infringing as it merely describes possible methods of implementation. It is unknown if DVSI will sell licenses for software that uses mbelib. If you do not have a license and are in a jurisdiction protected by the DVSI patents you should not compile or use this source code. If this list gets large enough I will move it to its own page so as not to detract from the overview of DSD.

A: Yes, if you want to listen live or save mbe data files, and are using a scanner for input. No radio or discriminator tap is required to play saved mbe data files. It should be easy for someone familiar with Mac audio programming to port it to the Mac. The RadioReference Wiki.
