Unfortunately the RigBlaster series of interfaces are not soundcards 
nor do they - as far as I know - provide any receive interface.  They 
are essentially a transmit interface that provides isolation and 
switching for the mic line. 

If you are getting started, connect the line output from your 
computer sound card to the Line In on the K3 and connect the 
Line Out of the K3 to the Line in on your computer soundcard 
and have fun learning all about PSK31.  If you don't want the 
Windows sounds getting from your computer to the radio, consider 
one of the interfaces with a dedicated USB soundcard, radio 
control (CAT interface) and other features in one box.  Such 
devices are made by several companies - I'm partial to the 
microHAM products (www.microHAM-USA.com) but then I distribute 
them in North and South America.
