You can do that. In fact I did that initially, I now use a Minicircuits
Lab 2 way splitter and an about 6 db gain buffer amp between my K3s and
the divider. This seemed to give me a bit better spectrum display. You
will need NO SDR protection as you are using the receiver IF.
I did use HDSDR during one of my early configurations. It just seemed
harder to set up than what I use now. But, it won't require spending for
an LP pan and sound card. Hmmm. I think I just got the answer to a
question I had raised about using the I&Q data available from the K4 USB
connector for CW Skimmer. I suspect the formats are the same.
Your description at the bottom of your note will work if all you want is
spectrum display, but to do serious integration like marrying up
logging, spotting spectrum display CW skimmer and then a contest
configuration, you are going to need to distribute and receive K3 band,
frequency, and mode data. Using Win4K3 suite with com0com does make that
easy and you could use what you describe using a pair of virtual ports.
Should work well.

Why not take the RX OUT of the K3 to a BNC T and the RX IN of the K3 to the
other side of the BNC T and with a BNC T in that path, feed that to the SDR
receiver. Then on the K3 press the RX ANT button and both are fed the entire
band from the same antenna and they are protected during transmit. You can
use HDSDR and OmniRig to control both the SDR receiver and control the K3.
With HDSDR and OmniRig it communicates both ways.
Two short BNC to BNC jumpers, a BNC T and a short BNC to the input on the SDR
is all that is needed.
