If you can get audio they work. The documented accuracy for WWV is within 1
millisecond of the time pulse.
Where is that documented and/or can anybody verify that they get results in
that range?
What is the (ballpark) of the day/night shift?
https://www.febo.com/pages/hf_stability/ shows the "about 1 Hz"
variation one sees in various places.
That's the apparent variation in frequency which is really the phase
shift changing during sunrise/sunset.
Looking at the 10 MHz data, it looks like there's a 0.1 Hz change
lasting about 2 hours. I think that's a change of 720 cycles, or 72
microseconds at 10 MHz.
