I just installed a new TX crystal into a KXN1052 channel element on a Micor exciter today. The crystal is from ICM. It will not come on channel. The ordered frequency is 445.125; it comes no closer than 445.1375. The crystal arrived late Friday PM, and upon installation Friday evening, the problem was discovered.
I realize I may need to contact ICM when the office opens on Monday since this is a new crystal. But, is there an easy and reliable way to warp it down without the need to perhaps send the crystal back? A small cap across the crystal? Related question--why would a crystal from a reliable manufacturer be off in the frist place. Are there tolerances in the channel element that can sometimes add up the wrong way? I have some other elements of the same number; is it worth trying the crystal in another one? Laryn K8TVZ
