I built two of the GPS Stabilized Oscillator circuits (G3RUH as modified by N1JEZ). They seem to work, except that I still have not been able to confirm that the 10 MHz XO (FOX) is truly locked up to the GPS signal. I can verify that the GPS Engine is locked, but I still cannot prove to myself that the XO is locked.
I made one up to lock up a 1 GHz PLO that I can use for calibration of my Service Monitor and the other to use as external references to a couple of EIP counters. Any thoughts or suggestions (other than using the services of NIST !!). 73, Dick, W1KSZ _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
