That's the way the K1 works, unless the leads to the VFO pot have been mis-wired. > I think the manual said it tunes the other way... 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*. > No one makes a 15 turn 10K pot? That would make it tune nice 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.
