Hi Tony;
Are there any specific instructions on how to access the appropriate files?
Get your RTL/E4000 tuners working and calibrated with SDR#.
SDR# Quick Start Guide
Don't bother with the following steps until SDR# works with both tuners.
Install VB Audio Cable (like VAC but free). Each "cable" is a separate driver - you'll need two.
VB-Audio Virtual Cable
Install DSD or DSD+.
Digital Speech Decoder (software package) - The RadioReference Wiki
DSDPlus - The RadioReference Wiki (suggested)
Install Unitrunker (current version is Release 27).

You'll need to create two folders for two separate copies of SDR#. Make a copy of your existing (working) SDR# folder with a different name. We'll call them "A" and "B".
Configure a discriminator only signal receiver in Unitrunker.
UniTrunker | Receivers
Configure SDR# "A" to send it's audio to VB Audio cable #1. Configure the signal receiver in Unitrunker to accept the audio from cable #1 as its input.
Tune SDR# "A" to a known control channel. Use narrow FM demodulation with a bandwidth of 7 khz. Clear the check box that says "Filter Audio". The signal receiver window in Unitrunker has an oscilloscope tab where you should see an active audio waveform. Mute this receiver so you won't hear the control channel noise.
At this point you should see a site window appear displaying call activity.
If you can get this far, you're half-way there. Let us know your progress and we can walk you through setting up SDR# "B" for voice following.
