Please refer to the HelpDesk article, How to Setup Virtual Audio Cable (VAC) 4.0x with PowerSDR for instructions on how to configure VAC. In this example, Com0Com is used for the virtual com port. This allows for wide-band reception of CW signals.
PowerSDR v1.14.0 and later has the ability to send the digitized I/Q data stream generated by the SDR hardware directly to CW Skimmer via a VAC audio channel. It uses I/Q data streams for the decoding of multiple CW QSOs. As noted previously, CWSkimmer is a program that decodes multiple CW signals all at the same time.
