John told me once that an easy way to deal with many classes of jumps is simply use a pair of OCXO. This is an easy solution for a time-nut (driven by interest and passion), perhaps much less so for a manufacturer (driven by market and profit). If we as a group find that unpredictable phase or frequency jumps are limiting GPSDO performance then that would be a fun group discussion on how best to implement a N-way XO GPSDO. If done to the extreme it could also reduce phase noise as a by-product. But let's not jump (!) to conclusions that Mike's problem is necessarily all quartz related. Given how little testing any of us have done on this particular GPSDO, speculation should take a back seat to measurement. /tvb _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
