[time-nuts] WWVB BPSK Receiver Project? (fwd)

Hi

With a reasonable sized data set, I suspect we would learn some things about
the phase shift process. The better we can model the process, the better we
can anticipate it and correct for it in the code.

Bob,

To address that diurnal phase issue, for fun, we could set up a
cloud-based time-nuts WWVB common view network. With a
couple of sites in each state, imagine the wonderful daily or
hourly animated plots that would result.
