Thanks Mike - That makes sense as we used to consider 20 to 25 khz per rev.
ideal in the good old days. Thoes PTO's and LMO's didn't have a free
spinning knob. 15 khz per rev. should work just fine, even with the smaller
knob on the K1. -Rick -

problem is *not* that the frequency changes too fast while tuning. It
doesn't. Rather, the real problem results from the the VFO potentiometer
having very very little resistance to rotational motion. This makes it hard
to remove one's fingers from the dial without imparting some small amount of
undesired pot motion.

the front panel. Put in just enough until you get that small amount of
rotational resistance that allows the dial to remain in position as you let
go of it.

There's a lot up there. Then there's the bonus of being able to copy 10000
kHz WWV on the 30m band (but you'll have to install that alternate 30m
hetrodyne crystal to get that).
