[Elecraft] K2 - NOISY POLLING

[Hank Kohl K8DD]

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!!
