"I used a Off the shelf clock Osc,, must have gotten lucky as the thing has
NO drift,,,, it will copy QRSS 60 for hours and stay on track"

Hi Bob,

Yah, you sure were lucky. I'd place the chance of seeing diftless QRSS60 performance with that setup at 1 in 100. If you don't believe me look at the specs for that clock osc and convert the PPM drift to Hz.
