On sideband, tight skirts (the electronic kind, gentlemen!) are

important, maybe more so than on CW. There is nothing neater than
listening to
a weak SSB signal through an IF system that has a 1.2:1 shape factor.
That
complete absence of interference on the sides is marvelous to hear.
I'd be
surprised if the KSB2 manages 2:1. Just tune through loud broadcast
signals on
forty meters sometime; listen to the audio "images" the other side of
zero
beat even on moderately strong signals.
Of course, every K2 is subject to variability in its construction and
alignment. While I'll agree the filter in the KSB2 isn't perfect, I am
not experiencing this kind of performance. I do not hear images in my
KSB2, even with the strongest 40m signals.
I would suggest something is amiss either with your BFO alignment or
with the construction of your KSB2.
