Thanks Frank,

The trace on the scope was derived from the oscillator. It was used to provide a more usable signal to the PIC chip. The oscillator was producing a near sine wave but nowhere near a pure sine wave. I thought it was pretty good to get that oscillator up to 20MHz on a "push-in" breadboard, but that was after I made the video. My oscillator was only an LC tank circuit so I needed a more accurate clock source for a reference to achieve an accurate reading. So I configured my PIC to run off an external XTAL.

Through good placement of components on the breadboard of which was learnt by trial and error.

Oh, I hate that, but been there done that. Well, not at 20MHz on one of those things.
