Hi Ron,
   As Dave mentioned, I run softrock panadapters for both my K3 and K2.

They're cheap but work very well. I have a Clifton Labs Z10000 bufferamp
between the softrock and the K3 (both are mounted within the same Altoids
tin). I'm using a Delta 44 soundcard and 96KHz sampling rate.

I simply followed the very detailed instructions on the Clifton Labs web
site: http://www.cliftonlaboratories.com

You have to be able to work with surface mount components for both boards.
Within a few weeks I got the kits from Clifton Labs/Tony Parks and with
minimal effort was up and running.

On the downside I currently have 2 mirror image and a one centre noise
spikes on-screen. I can't seem to get rid of them, but apart from that most
of the spectrum is useable. I can see signals that I can barely hear on the
K3. There is no K3 rx noise evident when the softrock is attached to the
KXV3.

My main useage is the following:
1) Monitoring for a band opening.
2) During each contact in a contest (search and pounce), I find it helps to
look where the next station is. This prevents me tuning over him when I've
finished the current contact and he isn't transmitting any more.
