I read the paper, but I could use an expert ruling from the list:
What does this actually mean for my Spectracom 8170 and Spectracom 8164,
i.e. the twins? The latter I frankly don't use much (I'm early in the
time-nuts disease progression), but the 8170 I want to continue to rely
on, at least to set itself. A little phase noise I can tolerate. But
the recent transmission-format experiments coincided (to a first
approximation) with the recent coronal mass ejection that knocked the
8170 on its ass for most of a week, so my observations are not conclusive.
The circuit (still a-building) to set my SWCC clock will take the 1PPS
edge, but the speed of the solenoid, not to mention the time constant of
the current-loop, I'm sure vastly outweighs this new source of error.
Right? Will the strip-chart recorder on the 8164 provide a new source
of amusement, as it tries to plot the 180-degree phase changes every second?
