Default Re: Quartz crystal accuracy over time

Quote:
Surface contouring is used by better crystal manufacturers to improve activity on chosen modes, and to worsen that on other modes but the effect is slight.
Thanks for clarifying that. So the information I saw is not a myth, but it is not always true and best not relied on even when it is true. I would generally expect to put some LC with the crystal in an overtone oscillator.
