Dave, Easy fix - just loosen the screws on the VFO knob and move it back a bit to create more drag on the knob. Be certain the felt washer is in place, that is the only thing that creates the drag - adjust the knob position on the shaft until the drag is right for your taste. If you initially adjusted the drag for a 'light touch', the felt washer may have compressed a bit and your current drag is not sufficient to hold the knob in position.
As a note for those with older K2s, I have found that the felt washer does compress and wear out after a long while, so for those with a similar problem, you may want to consider replacing it if the range of drag adjustment is not to your liking. 73, Don W3FPR > -----Original Message----- > > Good afternoon, > > Now that I have your attention, I don't really think that my K2 is > haunted, but it does seem to want to tune itself. > > As I tune the knob up and down the bands and come to the frequency that > I want to listen or transmit on, I stop turning the knob and I take my > hand off.
