As a new K3 owner, this gave me trouble for the first few days because the
behaviour I expected was indeed that selectivity would be increased as I
turned the control clockwise.

Although I have adjusted my head, it still seems wrong (to me).

Perhaps the reason for my expectation is different, though: I think of
decreasing bandwidth as if it were tightening a screw or making an aperture
smaller. Logically it seems like either of those operations would be
accomplished by a clockwise motion. Maybe it's just me.
