DMR Decoding with DSDPlus
DMR Decoding with DSDPlus
In this simple guide to setting up DSD, I show what you will need, and how to get started, along with a few other bits of useful information that I'm sure will come in handy when listening to digital voice. I also show some MOTOTRBO going through a repeater, and listening on the repeaters input channel.

DSDplus Trunking Setup 1.08t
DSDplus Trunking Setup 1.08t
This is how to install DSDplus to do trunking using version 1.08t available from the fast lane early access.
Some note from the maker of DSDplus:
FMP and DSD+ audio device numbers are "different" because FMP uses output devices and you were looking at DSD+ input devices (which is correct when linking to FMP/SDR#); in/out numbers can be different because you might have different devices, like an extra input or output device, which can shift all of the following devices numbers.
Also, if you make a device the default in or out device, it becomes in or out device #1 (IIRC), which again, shifts the other device numbers.
Network and site names have to be manually added to the DSDPlus.networks and DSDPlus.sites files. Systems do not broadcast these names.
When trunk voice following, the four FMP/DSD+ console windows ("DOS windows") do not provide much useful information; they can be minimized (by clicking minimize button in upper right corner of window)

RTL-SDR Tutorial: Following Trunked Radio with Unitrunker
RTL-SDR Tutorial: Following Trunked Radio with Unitrunker
The popular trunking decoding software Unitrunker now supports the RTL2832U R820T RTL-SDR directly in its new version. This means that extra SDR receiver software like SDR# is no longer required to use Unitrunker.
You can download the latest version of Unitrunker here.
In a normal radio system, one company (or talkgroup) might use a single frequency for radio communications. However, this is very inefficient as the frequency may not be in use for the majority of the time. In a trunked radio system, a small set number of frequencies are shared between a large number of talkgroups. Each radio receives a special computer controlled control channel. The control channel determines a vacant frequency that a particular talkgroup should use. This helps to make radio frequency allocations more efficient.
Because a talkgroup might switch between various frequencies often, it can make listening to a conversation difficult for radio scanners. Unitrunker can be used to decode the control channel and follow a voice conversation as it hops across various frequencies. With two RTL-SDR dongles you can set up a trunking receiver station with just Unitrunker. What follows below is a tutorial on how to set this up.

Improved digital voice P25 decoding with DSDPlus
We previously posted about the DSD digital decoding software
and it’s usefulness with the RTL-SDR dongle and other signal sources.
Now there’s a newly released version known as DSDPlus which promises to
deliver improved decoding and clearer audio of unencrypted APCO Project
25 (P25) radio signals.
This program is designed to be used with your RTL-SDR receiver software such as SDR#, with the receiver’s output piped to the DSDPlus program using a program such as Virtual Audio Cable or similar. Unfortunately, DSDPlus is a Windows-only offering at this time, and the anonymous author isn’t releasing the source.
DSDPlus is available for download from MEGA. You can find more the program user guide in the README file.
