PowerSDR must already be setup to operate CW with either a key or using the CWX (keyboard) form to send CW.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.
