View source for Trunked Radio Decoders

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. Newer applications such as UniTrunker, DSD and DSDPlus don't require the use of a data slicer. See the applications' page for more information.


Some of these utilities may also be directly addressed by [[Software Defined Radios]], such as the [[RTL-SDR]], or may be used via piping. For this unit, and possibly many others, see the [http://www.rtl-sdr.com/big-list-rtl-sdr-supported-software/ Big List of RTL-SDR Supported Software].


If you have questions about these utilities, please post on the [https://forums.radioreference.com/forums/voice-control-channel-decoding-software.26/ Voice Control Channel Decoding Software] forum. [[Software Defined Radios|SDR]] related questions should be posted in the [https://forums.radioreference.com/forums/software-defined-radio.193/ Software Defined Radio] forum.

===DMR Utilities===
* [https://github.com/IanWraith/DMRDecode DMRDecode]

=== MultiProtocol Decoders ===

These decoders support multiple trunked system types:

* [[Digital Speech Decoder (software package)]] - Decodes many voice trunking systems, including a few currently not supported on todays scanners (see below)
* [[DSDPlus]] - Software that decodes audio for NXDN4800 (Kenwood NEXEDGE and Icom IDAS), NXDN9600 (Kenwood NEXEDGE), DMR/MotoTRBO (TDMA inputs + both output slots), P25 Phase 1,  X2-TDMA, and ProVoice.  D-STAR & dPMR can be decoded but without audio.
* [https://github.com/chaoyi996/openear OpenEar]   Decodes [[DMR]], [[TETRA]], [[ADS-B]], [[NXDN]], POCSAG

* [http://osmocom.org/projects/op25/wiki OP25] 
** [https://github.com/boatbod/op25 BoatBod Fork of Op25, current development... ]
*** DMR (base station)
*** Yaesu Fusion - both halfrate vocoder (DN) and fullrate vocoder(VW)
*** Dstar
*** NXDN48 and NXDN96
*** P25 - Phase I, Phase II, and TDMA-CC
*** Please note that OP25 also contains a full stack of software encoders to enable voice transmission of all the above modes (for P25, o only P1/FDMA/FSK4 is supported). The TX package also includes a P25 P1 trunking control channel / voice channel simulator known as "fakecc" which broadcasts a P25 CC and one voice channel concurrently. An SDR with transmit capability (such as the HackRF or USRP), and/or suitable analog radio transmitter(s) are required for any of these TX modes.

===Development and Source Code===
* [http://www.radioreference.com/digital/wtrk/capture.zip Capture.Zip]
'''Description:''' Holds some C++ source code of a crude port of crucial portions the Motorola Trunker program. 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 .NET. This example runs in console mode and displays talk group information as it is decoded from the microphone input of the soundcard.
