In order to use you radio in ANALOG and DIGITAL Mode, you will need to download the following software from these locations. It is best you put them all into a separate download folder as not to have to search for these after you download in what may be a crowded download file you may already have.
HDSDR - Graphical Interface Radio Program
(Use the stable Version 2.76 (February 02, 2017))
When you execute the install make sure you put into PROGRAM FILES (x86) 32 bit folder if you have a 64 Bit Machine. If not put into PROGRAM FILES FOLDER.
If you are not sure if you have 64 bit technology, look in your C: Drive and see if you have two Program File Folders. One will say (x86)
Install the program and make a shortcut to your desktop.
This program can be opened multiple times. You will start one for each radio in your device. You will size the program screen to accommodate two or more screens.

ZADIG - Driver installation Program
Download the Driver Program ZADIG. You will find it here. Please note IMPORTANT. There are two versions. One for Windows XP and one for all other Operating Systems (OS) Make sure you download the correct one..
Once downloaded copy it to the same folder where you HDSDR program is. Paste in in the folder and make a shortcut to your desktop.

RTL2832U Dynamic Link Library
Put this .dll file also into your HDSDR program folder.

DSDPLUS Digital Speech Decoder
You need to create DSDPlus Folders under your C; Drive and unzip both files and their contents into one, two or three folders and call them DSD+1, DSD+2 and DSD+3
___________________________________________________________
VB CABLE - Virtual Audio Cables
Virtual Cables (software - VB Cable)
You will need to download 1, 2 or 3 cables from the website
VBCable (ZIP FILES)
Download Cable C for single radio. It is on the left side above the orange cable picture
Donationware. Consider purchasing additional cables via donation to enable multiple digital band monitoring as they will allow you to hear channels transmitting simultaneously without voice cancellation.
Just like DSDPlus these are ZIP Files and you need to create VBCable files under your C: Drive. Example VBCableC, VBCableB and VBCableA.
Extract the Cables into their folders and install them. Please note there is a SETUP and a SETUP64 bit. Choose the correct one. IMPORTANT - When installing the Virtual cables make sure you ARE THE ADMINISTRATOR of your computer. If not run "as administrator" when installing the cables.
Make a shortcut to your desktop for the DSDPlus application (exe file)
____________________________________________________________
DUAL RADIOS or MULTIPLE UNITS
You have two or three versions of DSDPlus and Three VB Cables. If you wish to follow digital channels on each version of DSDPlus then you need to have each running on it's own cable.
EXAMPLE:
DSD+1 - VBCable A
DSD+2 - VBCable B
DSD+3 - VBCable C (it shows as VB without the "C")
___________________________________________________________
So you need to start two or more instances of HDSDR and you need to start DSD+1,2 and 3 and when you start them you want them to automatically use specific cables. This can be easily done by using a batch file.
___________________________________________________________
You saw on the operation information how to set your sound setting defaults. When you open any DSDPlus.exe it will automatically open the default setting
EXAMPLE
input device - default VB Cable
output device - default - Speakers, Soundcard or Headphones
When you start the DSD+ program the screen will give you all your recording devices and all you Playback devices followed by the two default selections from that list.
This is fine when opening one DSD+ decoder. But when you open #2 and/ or #3, you do not want the same cable but instead VBcable A or B.
WRITE A BATCH FILE
Go to the DSD+1 and make shortcut to desktop. Run the program and make a list of the input/output devices which DSD+ numbers. Your recording cables may be #''s 1,3 and 4 for example with #1 being your default for DSD+1. That's fine.
Go to DSD+2 folder and create a new text file. When notepad opens you type the following
start DSDPlus.exe -i3 -o2
You have instructed DSD+2 to open the file using VBcable A or B instead of the default DSD+1 cable C. This is indicated by the number placed after the "i" for input. The output number is always your sound default which is probably
Playback output device 1 but if it is another number like -o2.
Now you need to save this into the DSD+2 folder. Name it DSD+2.bat and save as "all files" and NOT Text file. Then make a shortcut to your desktop.
Do the same procedure for DSD+3 and if you have a fourth or more you will have to duplicate one of the 3 VB cables.
The benefit is that if you are running multiple radios and there are simultaneous transmissions coming in, the decoders and sound will not cancel each other out with silence.
HAPPY HUNTING!!!
