I stand corrected! While the K2's local oscillator moves in an analogue fashion, the encoder steps under the control of the optical encoder according to the tuning rate setting. The minimum tuning rate is 10 Hz.
And, as Stephanie (VA3UXB) observed, if one chooses a larger tuning rate, the step rate moves up with it. Even though the PLL's reference oscillator is tuned by an analogue voltage, that voltage is developed in the digital circuits that moves it in step increments.

My K2 sounds continuous at 10 Hz only when tuning quickly. I can hear the steps easily on moving the knob slightly to a frequency 10 Hz higher or lower. 10 Hz with a BFO frequency of 600 Hz isn't as wide as a semitone, but it's an obvious step to me.
