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.
