Doc,

I am not certain why one would believe a control labeled "WIDTH" would
not increase the width as you moved it clockwise.  OTOH, if it were
labeled "SELECTIVITY", I would expect it to narrow the passband as it is
rotated clockwise.

While mine is one ham's interpretation.  I did not have the problem
because I always thought of it as WIDTH.  The graphic above the knob helps.
