Barry,
I had CW skimmer installed on my old winXP computer but was not
impressed with CW detection of weak CW (same for the K3). But I was
using K3 line-out audio so maybe I will try it with my new i5 64-bit
machine and feed IF via LP-Pan and UADC4 (brand new A/D converter
which supplies 96KHz dual IQ for diversity Rx).
The UADC4 is the latest toy for the digital-eme crowd (but should
find use outside of eme for general digital op). Its not cheap but
has totally flat audio bandwidth which is supposed to improve IMD
performance for urban users.
I am just building my new i5 win-10pro so haven't used it on the air,
yet. I will add a webpage for the UADC4, once operational.

Dave,
Your last comment is correct. However, CW Skimmer comes into its own
when you feed it IF I&Q data. You can see what is happening across the
band or a portion of it and still read the signal narrow band. You do
this by clicking on the signal you want to pursue and and listen in
narrow band. By clicking on the wanted signal, the radio is tuned to it.
This does require a little set up and setting offsets, but it is really
worth it. A little interesting point: in a little less than rigorous
testing, I found that that Skimmer seems to work a bit better using I&Q
data rather than just the receiver audio. But, that was not a rigorous
test and someone who is really interested can do the follow up.
