Build 2 or 3, and compare them against each other. (can't have too many frequency and time standards...<grin>) or, take it to somewhere that has a higher quality standard and compare or, just trust that the performance is inherent in the design, and if it works at all, it's good enough. Typically, if you are building a copy of a known good design, this is a good start. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
