Bernd Neubig has written a few documents on how to measure crystals properly, which should be available from Axtal's website, if I'm not mistaken.
Yes, I mentionend the Quarzkochbuch above. There was a nonstandard solution proposed by Detleff Burchard in UKW-Berichte / VHF Communications 4/92 but I can't find my copy.

The drawback was that one had to compensate C0, at least at 100 MHz. regards, Gerhard _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
