#135772 - are you sure it is not 1/3? Responding to: ???'s previous message |
In fact they start at a slower speed (always at about 1/4 of the normal)
To me it sounds as if you are lucky that most of your 3rd overtone crystals actually do 'overtone'. Verify that you are using a fundamental crystal and, if not replace it with one. OK, a guess. Erik |
