[Elecraft] K2 Anomaly

[Masleid, Michael A.]

--- and so, if you want the problem to go away, move the control
just a touch to get it away from the switch point.  On the other
hand, if you want the value to pop up from time to time, move the
control to the switch point.  Of course, that's like dropping a
penny on edge, it never sticks when you want it too.

A few years ago that anomaly got a lot discussion along with the one in
which the code speed will suddenly pop up on the display. 

IIRC, the most likely cause was that one of the DAC's that monitor the
controls and reports any change was right near a switch point, so very minor
variations on voltages or even just tiny changes in the response when it is
polled for data will sometimes cause it to report an change in the value by
one increment. Of course, the K2 is designed to display the change whenever
something like the power or keyer speed is changed, so it pops up on the LCD
for a moment.

I've always figgered it was due to my having brushed one of the knobs with 
my finger as I 'thumbed' the VFO knob around while tuning.
