If you want better performance than the 5370 frequency multiplier chain you should use a low phase noise frequency multiplier such as one of those listed or depicted at: http://www.eds-fl.com/~bruce/FrequencyMultipliers.html <http://www.eds-fl.com/%7Ebruce/FrequencyMultipliers.html> Bruce _______________________________________________ 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.
