check out the SoftRock Lite II SDR receiver from Tony Parks KB9RG.
You can use his 8.215 MHz SoftRock Lite II for K3 IF application that comes
with the xtal for the K3'a IF.
Then tap the K3's IF through a buffer amp and bandpass filter from Clifton
Laboratories.
Run that output into a sound card capable of at least 48khz and you have your
feed for the CW Skimmer software.

get out your soldering iron Gary, this can be done the old fashioned way for way
less than $500 bucks.... did I mention it's also fun? <g>
P.S. if you spring for a better sound card (96khz or 192khz) you might get a
kick out of the NaP3 software. Using LP-Bridge you can even use them all at the
same time off the one K3 Serial Port.

Ah, I'd never heard of sdr-iq but I just looked for info on it and
for a $500 price tag, I'm not interested. The limitation of +/- 12
KHz with an additional piece of hardware doesn't thrill me either. To
just have the audio be worked with has for me no practical function
so I won't bother. I've heard the K3 described as a SDR radio and
thought the needed outputs would be readily available. Apples &
oranges I guess.
That's what I needed to know & thanks.
Now back to DX

If you use an sdr-iq with the K3 CWS will decode up to 190 kHz I
believe.

CW Skimmer is indeed a pretty cool piece of software, but it doesn't
work like that. Unless you also have some sort of SDR front end,
all you'll be able to get with CW Skimmer is a display of the audio
passband. For a display of stations outside that passband you need
an additional piece of hardware that takes the IF out from the K3
and processes it so that it can be handled by your sound card and CW
Skimmer. Even then, CW Skimmer has a limitation in "IF mode" that
restricts what you see to something like +/- 12 KHz.
Even if you decide to go with something else, there's a lot of good
information on the LP-Pan website.

I'm always curious to try a new software & I thought CW skimmer
looks interesting. I'm wondering if anyone here is using it with
their K3 and if so, what did you find was the best way to connect
it to the K3?
I have both the internal Realtek soundcard built into the PC
motherboard and I have a E-MU USB soundcard which has XLR & 1/4"
inputs for left & right. There's optical & S/PDIF inputs as well
but the K3 doesn't have those outputs.
Thanks,
