Thanks for the information Scott. Since the only difference I see is the two capacitors, I wonder what makes it more stable. Perhaps it is a difference in the crystal itself. Have you ever seen a place where the subject of how the channel elements are individually temperature compensated (as when you send your channel element into the crystal manufacturer) is explained?
