Within the past few years, numerous folks have devoted their time and energy to writing software applications that allow you to use your computer and scanner to decode trunked radio system control channels. Many of these applications are freely available from these pages for scanner listeners and hobbyists. They also allow Trunktracking for Motorola and EDACS trunked radio systems using a two scanner setup.
Please note! To implement these applications, a good bit of technical skill is required. You must have a good knowledge of electronics, computer systems, and trunked radio systems.
For more information, check out the Trunker Yahoo group
Steps to getting Trunker / Etrunker running
2. You need connect this interface to the discriminator output of your scanner, NOT the audio output. Trunker will NOT work with anything but the discriminator output from your scanner. Most scanners do not have a discriminator output jack, so you'll need to tap it yourself and provide the output.
Source Code / Compiling Yourself
- Trunker 3.83 source code - available for download.
You'll need the Watcom 9.0 C++ Compiler to compile the source for your own application.
Receiver Specific Notes
- Here is a schematic (PDF file) for an interface used with Trunker and a Icom IC-R7000. For this example, a PRO-43 scanner is used to obtain the data channel. The interface obtains power from the Icom, so there is no issue with weak ports not being able to power the slicer. The IC Chip used is a MAX203 for minimum parts count, but a MAX232 would work just as well. The MAX203 can be obtained from Digi-Key. This interface has also been tested with an Icom IC-R7100. This interface may also work for other radios that use TTL serial levels if another source of 9-12V is available, or 5V if the regulator is left out. (Thanks to Gene!)
