That's the way the K1 works, unless the leads to the VFO pot
have been mis-wired.

The frequency of the VFO does tune *lower* as the VFO pot is
turned clockwise, but since the VFO frequency is subtracted
from the filter board hetrodyne oscillator frequency to generate
the local oscillator frequency, the operating frequency of
the K1 *increases*.

I have always been perplexed by the persistent claims that K1
VFO tuning is too rapid or too touchy.  It definitely is neither,
even if the 170 kHz VFO option is used.  What is touchy is the
VFO pot *shaft*, since it has no substantial resistance to motion.
When you remove your fingers from the knob, it is almost impossible
to keep from introducing some minor position disturbance.  This can
very easily be eliminated by the addition of some thin soft felt
"washers" around the VFO pot shaft between the back of the VFO knob
and the front panel.  A small amount of shaft resistance to rotation
greatly improves the feel of the tuning, regardless of the VFO span
option used.  I know of no one complaining of K1 VFO touchness who
has bothered to try this often repeated and very simple solution.
