Hi Hans,
One possible reason why the problem does not show up on all K2s, assuming that they are all exposed to the same strong signals, is that all K2s are not exactly the same in terms of actual component values due to allowed tolerances, which in turn can result in a different behaviour of unwanted 'sneak paths'. There are several other possible reasons which include mechanical construction, but to keep this short I'll not go deeper now :-) A related subject is 'Birdies'.
73,

This is my second K2, and I didn't experience something even similar to this in my previous one.
