Too bad but I hope the manual helped you avoid waisting coultless hours
trying to fix the unfixable.
I had good luck several years ago using the 1 PPS from a GPS receiver to
compare with the 1 PPS from a divider from a frequency standard to track
the frequency standard's drift. I used a frequency couter in the period
measurement mode and logged it daily. After observing the log I would
adjust the frequency standard. Earlier adjustments let me calibrate the
adjusment, which was on a 10 turn pot with a nice dial. Once I had the
dial calibrated in frequency shift, I could pretty much put the standard
on frequency. Once I got good at that, I could predict the daily drift
of the standard and could make the adjustment based on that.
I found it very educational doing all this. Its nice to share my hard
earned knowledge. I hope you enjoy doing it too.
Best new year and 73
