I got rid of the computer polling noise on both of my K2/100's by
removing the right side panel and tucking the ribbon cable up as
high as possible - away from the main board.
Not that I would recommend doing it the way that I did it (with
the power on and CTWin up and running), but I could hear the
polling noise go away on each radio as I tucked the ribbon cable
up as close to the top cover as I could get it.
Again I would not recommend that you do it with power on unless
you like living on the dangerous edge of life .... in the K2 lane!!

I guess that my setup is just plain awkward. I had a lot of computer noise until
I connected the shield end at the computer as well as the K2 end.
Can't explain why it worked, but it did...not a peep now. Worth a try.

Chris,
Just a wild guess, but you may want to check the cable between the K2 and
the computer - make certain the cable shield is connected at the K2 end and
is NOT connected at the computer end - if the shield is connected at both
ends, you can get some induced currents on the cable, but I don't know how
it might be coupled into the K2 audio.

Does anyone else have a problem with noisy polling with their K2 when
used with a computer logging program, and is there a cure for it?
I have two K2/100s which both have the 160m, NB and DSP options and
one has the SSB option. I am using N1MM Logger with an old desk-top
(about 300MHz) computer under Windows 98 and when I listen to the SSB
K2 on any band with the AF gain at minimum, I can hear a soft pulse
every second or so. This does not increase as the AF Gain is
advanced and normally the sound of signals, etc masks it, but it is
slightly annoying when tuning on a very quiet band.
