[time-nuts] Second Units? KS-24361

[Bob Stewart]

Hi Paul,
I saw the phase of the 10MHz signal dip by about 60ns twice today as compared to my homebrew GPSDO.  Given what I know about the design of my unit, it's hard to believe it could follow the path the phase difference took, but I suppose anything's possible.  Bob posted a graph showing the KS moving about +/- 15ns recently.  I would certainly like to know if others have seen this big of a phase movement.  It's been on about a week since the last power-off to replace REF-1.

I will say that I am watching the noise of the pps ti in the z3811 program.
Granted its been running 30 some hours now. Virtually nothing in time. My
fingers are crossed it will clean up.
I do like the unit quite well. Have to thank Bert for even cluing me in.
So I do agree quite a nice unit.
Regards
Paul
