CWSkimmer is a neat little program that decodes multiple cw signals all at the same time. This is my particular information relating to setting up CWSkimmer to work with my SDR-1000 and Edirol FA-66  soundcard.

  • PowerSDR and the SDR-1000 must already be setup to operate CW with either a key or using the CWX (keyboard) form to send CW.
  • A virtual com port (Com0Com or vCom) must be setup for CAT control.
  • The CAT parameters must be setup in PowerSDR (port, baud rate, and number of stop, data and parity bits)

The program can be downloaded from Afreet Software and has a 30 day trial period after which it must be purchased for a nominal fee. Installation of the program is straightforward by following the prompts.

You can see the PowerSDR program in CWU mode with standard settings (VAC is NOT enabled)

For the Audio settings (Figure 2), I selected:
  • Signal I/O = Edirol FA-66 In 2
  • Audio I/O = Edirol FA-66 Out 1 (not applicable, but it needed a selection)
  • Left/Right = Q/I

For the Radio Settings (Figure 3), I selected:
  • Hardware Type = SoftRock-IF
  • Audio IF = 9600,
  • Sampling Rate = 96kHz (same sampling rate as the FA-66),
  • CW Pitch = 600 (same as the Pitch frequency in PowerSDR CW Mode Controls - see Figure 1)

Default settings for CAT control set up to match the CAT configuration in PowerSDR for the virtual com port data parameters

Here are a few stations being decoded at the same time - what a neat little program!
