[Elecraft] [K3] APF and Pitch

[Ron D'Eau Claire]

Right, Pf. 

Also, the larger percentage of difference between two signals at lower audio
frequencies makes it easier to filter the unwanted signal out, either with a
physical filter or using the "gray matter" filter between our ears.

thanks Ron, I guess this relates to Q=f/deltaf ? Didn't even think of this,
and it's interesting that the effect is noticeable at these frequencies.
