It sounds like a really nice oscillator. I'm sure that everyone would
love to hear about the challenges and tradeoffs in designing such a high
performance quartz oscillator.
Do you guys cut your own crystals? How much of the improvement comes
from a better SC-cut crystal and how much from better electronics or
better ovens? I could go on and on, you wouldn't want to sit next to me
on a plane.
