Thanks for  the comments, everyone.  An SDR certainly makes the experience
in the shack even better.  Steve, I do have VAC on my PC but I have not
figured out what it does yet, your comments are interesting.  AFter 24
hours, I have used my SDR-IQ with CW Skimmer ( amazing with an SDR) ,
SDR-Radio, Winrad, and SpectraVuew.  I have finally figured out Winrad and
SpectraVie, while both appear "geeky" they do work quite nicely and have
useful features.   The only thing I have not got running is Multipsk with
SDR-Radio, Multipsk with wide panadaper display PLUS SDR-Radio is too much
for my PC.  I am surprised because I would have thought a P4 with 2.3 CPU
and 1 gig of RAM would have been able to run just these two applications.
However, SDR-Radio in is "technology preview" takes about 55% of my CPU even
at the lowest display settings and least bandwidth.  I assume beta releases
will see that improve.  Multipsk in is regular use takes about 15% CPU but
increases to 30-40% when I activate the SDR features, even with just 44 kHz
display .  The two combined crawl to a halt.  So I need to play around with
my PC some more and see if I can dump any loaded background applications.  I
will also try Multipsk with Spectravue and see what happens...
