Kali Linux - Cubic SDR and DSD Plus

The overall goal here is to connect a Nooelec USB antenna to Kali linux and listen to police frequencies that are digital and trunked. You will use the Cubic SDR frequency tuner and a virtual audio feed while DSDPlus decodes a digital signal to analog audio. The flow is as follows: antenna -> digital signal input -> Cubic SDR -> DSDPlus -> analog audio out.

Download DSD Plus v1.101 and v1.101 DLL and put all extracted files into the same folder. https://www.dsdplus.com/download-2/

sudo apt-get install cubicsdr

From the command line, temporarily set up virtual audio sink with:

pacmd load-module module-null-sink sink_name=Virtual_Sink sink_properties=device.description=Virtual_Sink

Click volume control to see a Virtual Sink in the pulse audio i/o devices.

If not, then try restarting pulse audio with killall pulseaudio, systemctl --user restart pulseaudio.service

To make the virtual sink option permanent, open the configuration file (sudo gedit /etc/pulse/default.pa) and add the following line at the bottom of file)

load-module module-null-sink sink_name=Virtual_Sink sink_properties=device.description=Virtual_Sink

If wine is not already installed then,

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install wine:i386
sudo apt-get install wine32

From your DSDPlus directory run wine DSDPlus.exe

At first I got an error: wine_process_init L"C:\\windows\\system32\\-h.exe" not found,
so I deleted the /HOME/.wine directory
and ran regedit to recreate the .wine directory.
Then I ran wine winecfg and selected auto detect drives.
Finally, I was able to run wine DSDPlus.exe successfully.

Start CubicSDR, which should be in the Kali Linux Menu

Tune to desired frequencies. Both Cubic SDR and DSDplus should display wave activity.

This is what volume control playback should look like:

These are Los Angeles Police frequencies: 506.937MHz and 507.212Mhz
