Thank you Darrell,
I checked the pulse width, and in fact it is 500 usec or broader, while
the KNB2 spec is 10 to 70 usec.
Seems I have to play with C11 and C12.
Still, if could get hold of a diagram, that shows what to measure
where, it would be appriciated.

Karsten,
Sounds like the noise is outside of the KNB2's range. There is a mod for wider
spaced noise like you describe. See
http://www.qslnet.de/member/la3za/K2/modAny.html#KNB2
What you describe sounds like an electric fence.
There was some discusion about an improved noise blanker on the mailing list a
while back. Perhaps Wayne or Eric might comment on whether Elecraft will be
introducing a new noise blanker in the future.

I have sharp pulses on all bands hitting the band about once per second,
which the noiseblanker of my old IC 735 kills, but not so my K2 S/N 4765.
I can - more or less - read a circuit diagramm (I don´t understand each
components function in detail yet) I´ve tried some signal tracing,
couldn´t identify a faulty component and can´t find out, what is wrong.
Is there an info-sheet available, what has to be seen with a
dual-scope-oszilloscope at which point and at what siganl level?
