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. In addition, except Pro96com, UniTrunker and some MPT-1327 apps, you must 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.
If you have questions about these utilities, please post on the Trunker/Etrunker/T4Win Decoders forum at Radioreference

MultiProtocol Decoders

These decoders support multiple trunked system types:

  • UniTrunker - auto-detects and decodes the control channel data for APCO Project 25, Motorola, EDACS, EDACS ESK, and MPT-1327 systems. Limited support for LTR. GRE PSR-500 / PSR-600 and Radio Shack Pro-106 / Pro-197 and Uniden BCD396XT / BCD996XT do not require discriminator tap (Unitrunker can use the PC/IF data stream output from these radios via the programming cable). All other radios require discriminator tap.
  • UniTrunker (Retro) - auto-detects and decodes the control channel for Project 25 9600 baud, Motorola 3600 baud, EDACS, EDACS ESK, and MPT-1327 systems. Earlier generation limited to a single decoding session. Also capable of using PC/IF data from GRE and RS scanners.
  • T4Win - development has ceased in favor of Unitrunker, above
  • TrunkMon for Motorola and EDACS systems
  • TrunkPCR Motorola and EDACS trunking for the Icom PCR computer-driven receivers
    • See our TrunkPCR article for tips on how to use this software. The PCR-100 requires a discriminator tap, the other supported radios don't.

Project 25 9600bps decoders

  • PRO96Com
    • Description:: This utility is designed to log and map 9600bps APCO-25 trunked systems only using the following models of scanners:
      • Radio Shack (GRE): Pro-96, Pro-2096 (trunking stream monitoring only), Pro-106, Pro-197 (trunking stream monitoring or as secondary radio)
      • GRE: PSR-500, PSR-600 (trunking stream monitoring or as secondary radio)
      • Uniden: BC250D, BC296D, BC785D, BC796D, BCD996T, BCD396T (secondary radio only, controlled by PRO96Com) BCD396XT (trunking stream monitoring or as secondary radio) Note: The BCD396XT must have the control channel in a programmed system and be in the hold mode to decode.
      • AOR: AR5000 (secondary radio only, controlled by PRO96Com)
    • Plans for 3600bps Motorola support is planned for a later release for GRE PSR-500/600 only (the Pro-96 cannot be supported due to the fact it does not output the necessary data). Of note, PRO96Com does not require a discriminator tap.
    • PRO96Com Yahoo group support

Motorola Decoders

  • Trunker - The original DOS based Motorola Control Channel decoder. Provides scanner control and basic talkgroup/id tracking.
    • The Yahoo support group for Trunker and its variations can be found here
  • MTrunker ported to Win32
    • A forum for this software can be found here
    • You will need .RAR decompression software, such as WinRAR to decompress this file
  • Treport - mainly displays diagnostic information for a Motorola trunking datastream
  • Trunk88 - A Trunked Radio Decoder for Motorola Systems. Very similar in operation to trunker, will control most Uniden radios, will accept data slicer or SB16 compatible sound input. Program download is here. Support can be found on the TRUNK88 Yahoo group.
    Now supports The PSR500/PR-106, PRO-107, and Uniden "XT" radios. Note: The XT radio and PRO-107 must have the control channel in a programmed system and be in the hold mode to decode.

EDACS Decoders

Description: Displays EDACS Diag Information for EDACS systems.

Description: A version of the Etrunker EDACS decoder that supports EDACS System Key (ESK) systems.

Description:The E-Trunker Utility. Decodes and Displays information from the EDACS Trunked Radio Datastream. This version is dated 07/27/2001

Description:Utility for managing EDACS talkgroups in the Etrunker program. Note this is a DOS application, but is compiled to only run under Windows.

Description: Translates decimal IDs to EDACS AFS format. Select from the left frame about 1/2 of the way down

MPT-1327 Decoders

LTR Decoders

Description: Eric Cottrell has graciously compiled LTR, Passport and MultiNet Tracking support into a trunker like interface. 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 and an updated version here


Winradio Trunking Decoders

Development and Source Code

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.

Description: Source code for the Trunker / Etrunker decoding applications. This is the full C++ code for both applications

Miscellaneous Utilities

Description: DOS Type I utility to convert hex or decimal values to all Sizecode variations. And now supports converting a hex or decimal number to Uniden AFS.

Description: Conversion utility for DUMP.TRE to TREPORT.OSW [Initiate load with 'O'] "OUT2OSW /6 treport.osw"

Description: This spreadsheet for MS Excel allows you to figure various options for frequency defined systems (VHF/UHF). 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 800 or 900 frequency, and define a configuration for programming a Motorola radio or system.

Description: kNACk is a tool for receiving the NAC codes for Motorola APCO-25 trunked system control channels and non-trunked channels using APCO-25 digital modulation. (NAC codes are roughly equivalent in APCO-25 systems to PL or DPL codes in analogue radio systems. Presently the only radios on the market that can auto-decode NAC codes "on the fly" are the GRE PSR-500 and PSR-600, Radio Shack Pro-197 and Pro-106, and Uniden 396XT and 996XT models.)
