I measured mine again last night. About 5k also. I think I must have
been regurgitating the 32k as a result of the Q measurement which
was definitely about 6. You must be right - there is some non-
linearity going on there. However, I still think the resonant
frequency method of determining Xl is valid. Forget the Q measurement.
