Bernd - Get a gps with 10Khz or more out , i think the 10Khz jupiters are "gone" , but a LEA5-T or LEA6-T could output ie. 1Mhz , the divide the OCXO by 10 and phaselock the 2. Use "millers" XOR http://www.jrmiller.demon.co.uk/projects/ministd/frqstd0.htm Or this one using a 4046 http://gpsdo.i2phd.com/ Pure "Analog" CFO Denmark _______________________________________________ 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.
