Can the KX3 RX I/Q output be used with CW Skimmer?

Hi all,

First post here.
Can the KX3 RX I/Q output be used with the CW Skimmer program?

Anyone any experience with this…love to hear.

Gerard,

The simple answer is yes, sure. If you are using the I&Q data for
spectrum display, you tell CWskimmer to use that very same data
stream/sound card. It only really works with the Windows MME driver and
only sometimes works with the ASIO drivers. Ihave been doing this now
for about 6-8 months with absolutely no problem.

I have successfully used the KX3 RX I/Q with CW Skimmer. You will need a sound card with stereo input (Signalink won’t work) and possibly isolation transformers on the input to the sound card to remove spurious signals. I used a Griffin iMic which is not the world’s best sound card and isolators from Radio Shack. If you are going to buy a sound card for this application get one with at least 96K bandwidth so you can see the entire CW sub-band on most bands. Also, I had to change the Skimmer settings to use Q/I instead of I/Q. Once you get it set up it is great. My goal is to get a PX3 and run Skimmer off of the PX3 output. I got to play with it one weekend and it is the ultimate setup for CW contests that allow assists.

What settings do you use? I was just using the 3kHz radio option.

Re: Can the KX3 RX I/Q output be used with CW Skimmer?

Gerard,
You will need to set up using:

softrock-IF
CW Pitch to what ever you set it to
Audio IF = 8000 - CW pitch

There will need to be a little adjustment of the IF due to your sound
card not being exact.

You will also need to set CAT to KX3 and appropriate com port. When you
get Audio IF set correctly, the frequency readout in the box at the top
of skimmer will read your radio's frequency and the little green
indicator will be right on the signal you want to read.

Scott,
OOPS! I picked up Gerard in the thread. However, my response of
just a few minutes ago is correct. In your case I should have added that
you need to set the signal I/O device to the sound card you use for the
spectrum display. This way you get more than just the 3 KHz bandwidth
you are using and you can use narrow filtering for listening without
effecting what skimmer is doing. I hope this is all clear.
