On 40 CW, there were some strong signals to my 28' vertical.  30-40 dB
over S9 was not uncommon.  I noticed with one of these stations, I could
hear "clicks" up and down the band for +/- several KHz.  I though he had
key clicks.  Then I found a 2nd signal that produced the same results.
Then a 3rd and a 4th.  I suppose it is possible that all of them had
issues with key clicks but it is also possible that I've hit a limit in
the K2's ability to handle strong signals close in.

All of the signals were strong.  K2 doesn't do this as a rule on S9
signals.  In fact, this is the first time I've noticed it so I'm going
to say that signals 20 dB over S9 don't produce it (I'd have to double
check that though).  This makes me think it is an issue with only very
strong signals.

Keith, just for clarification, You say 30-40dB over S9 for 4 stations caused 
key clicks.
Then in the second paragraph you say that signals 20dB over S9 don't produce 
it.
I think you are saying that before you installed the KAF2 the 20dB over S9 
signals
did not have key clicks. Is that correct? If so why not take the KAF2 out of 
the
circuit and see if that was the case?
