David,

I just wanted to know if your cable was still in place before opening my K2. 
I have the same noise problem, especially on 20 m, and guessed that the 
cable was the cause of it.

So, I just removed the counter cable.. (and changed the ribbon's position), 
but that noise is still present. So, back to square one.. ??
