Likely a worn/dirty encoder. They can be changed if you are
comfortable doing so, otherwise Elecraft service are experts
in restoring the K3/K3s.

My Elecraft K3, Serial # 6375, I bought in 2012 and built. It has been and
still is a great rig. The only problem now that is irritating is the power
control is erratic. Sometimes it will not change, sometimes it moves the
power increments slowly, erratically. The Comp position of the control
exhibits the same erratic behavior. I am not sure if it is the potentiometer
or something else.
Any ideas on the cause would be greatly appreciated.
