As long as you don't have sunset or sunrise between you and the transmitter,
WWVB is reasonably stable. At night you will get more signal, but also can
have some skywave stuff in the mix.
One man's noise is another man's signal.
The NIST coverage maps vary widely from night to day. I

Hi
The zero crossing is very arbitrary. If it's correct at the transmit site, it
will then be off everywhere else by the speed of light / distance. You will
appear to be correct once every wavelength away from Colorado (roughly every 3
miles). You won't really be correct because you are

Yes nights are bad for me, east coast and MSF interference.
So it could be any number of 60 KHz crossing its just odd it lined up the
way it did and I double confirmed that I was not doing something silly like
using alternate triggers.
Very careful analysis does show a 1-2 us jitter and at

Hi
Well between now and midnight, you will completely loose signal at least once.
It's a pretty dramatic amplitude dip as sunset gets right to the wrong place.

Might loose the signal not unusual and it did shift +5-8 us tonight aligned
to the diurnal shift.
So maybe this is not so crazy of an approach.
