It sounds like the original crystal may not be a standard cut that would be used for that frequency. Did you tell ICM that the crystal was in a VXO? Did you send them a schematic of the oscillator? I would think that they would still want to make things right with it. 73 -Jim -- Ham Radio NU0C Lincoln, Nebraska, U.S.S.A.
