> The highest Q I remember seeing were BVA's that reached 2e6 to 3e6 @ 5MHz
What determines the Q of a crystal? Is it atomic level impurities? Crystal defects? ... How has that changed over time? Is there a Moore's law for crystals? How does the quality of crystals used for timing compare to the crystals used for semiconductors? Are there any other economically significant uses of high quality crystals? -- These are my opinions.
