Here is my configuration for using CW Skimmer. Below is a screenshot of the working program on 20m - multiple stations are being decoded at the same time.
Here the Anan interface of PowerDSRmrx shwoing VAC enabled.
To get to this point, you must have VAC enabled with Direct I/Q output to VAC enabled in the PowerSDRmx VAC section
To control frequency, I have ID’d my radio as a Kenwood TS2000 in the PowerSDRmx CAT section.
Here are some screenshots of the set-up tabs as I have them configured in the CW Skimmer options
