Ron, AC7AC, said: The K2 does this by using a PLL that tunes in about 5 kHz "steps" and then varies the PLL reference oscillator's frequency to tune smoothly in between those steps. So the tuning has the true smooth feel and spectral purity . I say: When I tune my K2 past a signal, I can hear the steps. I also sometimes think I can hear steps when I tune my K1 thru a signal. I assumed that this is due to the nature of the multiturn pot. I think it is wire wound and that the wiper cuts the wire turns suddenly. It could also be due to jerky tuning , in spite of efforts to the contrary. It is very subtle, unlike the K2. Give me a smooth PTO with the K2 signal path. My long term idea is to build a stable analog VFO, using my Sierra band modules for premixing, to drive my K2.
