If microwave ovens could be an issue, could current popular mobile phone/tablet
(Qualcomm Snapdragon, Samsung Exynos, Apple A7/M7) and low power desktop (Intel
Core) processors running at nominal 1.4GHz also be an issue?

If so, don't miss the Nobel Prize potential :-)

Jim,
Check IF level and H2 pressure. Also see if OCXO tuning is near a rail. Go back
through the past month and look at trends on all the parameters. You are
logging all channel data, I hope.
Also check your microwave ovens: http://arxiv.org/pdf/1504.02165v1.pdf ;-)

How are related the three locations' jumps? Do they occur at the same
time? One more than the others?

Is there a direct digital divider chain to the PLL which steers the
5Mhz OCXO ?
If so the obvious t
Hi all,
Has anyone here who is familiar with hydrogen masers ever experienced a
sudden jump in phase of the 5MHz output?
We have found they occur semi-regularly (few times a week) and are trying
to find a culprit.
The weird thing is that the jump is ~0.7ns and that 1/0.7E-9 is close-ish
to 1420.
