I just got DSD plus hooked up with unitrunker, using VB cable as audio input on DSDplus/output on unitrunker, trying to listen to ARMER Allied Radio Matrix for Emergency Response (ARMER) Trunking System, Various, Multi-State Have frequencies on Hennepin East's control channels but only hear little bits of p25 audio. I have followed multiple tutorials and have gotten nowhere. My health is always at 0. I keep getting what I think is an error on DSDplus's output. Any help is appreciated in advance

Bad signal or simulcast distortion would be my guess.
Edit: Might want to turn the audio output for the signal vfo in unitrunker off, maybe they are clashing, but not sure why you're health would still be zero unless its a qpsk system and not c4fm?

The OP
Unitrunker 1 + DSD is obsolete. Try Unitrunker 2 which does not require janky virtual audio cables and offboard DSD decoders. Also, your SDR driver installion is problematic as you *should* be installing the composite device. Head over to the Unitrunker Google Group.

You're never going to decode anything with a window value of 100+. You need to apply correction to the dongle in order to center the frequencies. You want to get the window as close to 0 as possible, +/- 5 is usually close enough. Start by applying whole numbers in the correction field, starting with either 3 or -3 and go check the window value. Tinker with that until you see it lowering. Then fine tune it by using decimals, normally only need to apply tenths like 3.2, 3.5, etc.

Dumb question but...

I got it installed and 2 SDR's running. Now what? Is there some tuning mechanism or a place to enter control channels?
