>>17268633You're not an electrical engineer, if you were you'd know about the sort of precision needed to achieve a high quality accurate quartz crystal. For example, if you're into radio (you're not LOL) you'd know that a precision receiver requires an oven stabilized quartz crystal to maintain accuracy. Every year we hams have a competition to see who can regulate their receiver the best actually.
Good quality precision quartz crystals can not be manufactured in bulk, they have to be individually selected for their material properties, or engineered / grown, then laser trimmed, aged, and possibly trimmed again.
You're probably a bot. It's sad. Post an image to prove you're not a bot. One showing some quartz crystals aging in an oven.
