Another interesting detail, I think. For the KX3, if I recall
correctly, both the QST review and Sherwood's tests indicated that the
audio image (opposite side of zero beat) wasn't all that far down, like
60 dB, and limited close-in dynamic range. I don't recall any such
qualifications for the KX2, and indeed mine doesn't seem to have an
audible image even on the strongest signals. (Not a scientific test, I
know, but I think I'd hear an image 60 dB down.) If this is so, what is
the difference responsible?
Note that the optional "roofing" filter in the KX3 is really just an
audio filter. While it may improve dynamic range beyond a few kHz, it
has no effect on the image.
