DSDPlus-Raw-Input_2014-03-27@103407.wav
Not sure what link will work, but it's in 2 places.

I got the following (as it appears to be a fairly weak raw NXDN capture):

C:\Users\br0adband\Desktop\sdrsharp\dsdplus>dsdtune_v3.exe -i DSDPlus-Raw-Input_2014-03-27@103407.wav -fn
Checking option -dr
Running dsd.exe < DSDPlus-Raw-Input_2014-03-27@103407.wav -o0 -O NUL -fn -drXXX

Switches you want to use :
-dr3 -dh2 -ds68 -dd15 -dv3

Input level seemed to be about 8-9% overall, might have better luck with trying to improve the reception just a bit even in spite of the tuning potential (which isn't all that great to begin with).

That was the City PD Dispatch, since the switch to NXDN, it seems that their signal is over half of what I use to get.
The Campus PD seems stronger, same type of system as the City.

Switches you want to use :
-dr3 -dh2 -ds68 -dd15 -dv3

Those cleaned it up a bunch.

Thank You.

Here is what it sounds like after adding the switches.

DSD - YouTube

Seems like an awfully strong signal there considering the peak on the spectrum, and it still required the tuning even in spite of that strong signal?

Yes it did.
Thank You again for your help.
I also changed antennas.

While you can have other run that program, DSD Tune was meant to give you the best numbers from your setup. It's design was to take your computer and your reception and give you the best numbers your setup can provide.

It may be a strong signal, but the raw audio being fed to DSD+ looks like it has frequency response issues.

The raw audio is from the OP's setup. His/your/anyone's copy of DSD Tune and DSD+ isn't going to behave any differently with that audio file than anyone else's.

I did run it, and got the same results.
After changing antennas, and rerunning DSDTune it changed, and sounds much better.
Again Thank You Every One for the help.
