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
Dick,
A newer dual trace 'scope some patience can tell you a bunch.
A 500Mhz 'scope set to 2nS/div with the 10MHz OXCO outputs on chA chB,
triggerred on A (or B) has
a sensitivity of 2E-9/s for the traces drifting apart 1div. If you can get
both zero crossings on screen (variable delay
line
for that Invar rod !!
Thanks, Dick, W1KSZ
