Dave,
I suppose it could be something in the encoder, but I can't tell from your
description. But if it's not...
Hold the dial skirt steady and turn the knob slightly. That will reduce (or
increase--depending on direction; I'm at work and can't recall which direction
does which) the friction from the pads on the chassis.
Sometimes the felt pads that are used for drag wear out. You can remove the
main tuning knob (slide off the rubber ring and unscrew the set screws, then
slide it off the encoder shaft). You can see if the pads are worn out and
attach fresh felt to the springs.
Now, if it's the encoder that's squeaking, I am aware of nothing you can do
to fix that save replacing it with a new encoder.
73 and good luck,
