Could someone be so kind and could explain me what the problem with
the BPSK modulation is? I mean the phase of WWVB shifts around several 10us
during sunrise/sunset already... Not to talk about the changing propagation
conditions. Just see  for an example of what's happening.
Yes, for those devices that lock on the phase, you'd have to change
their correction/detection loop, but overall, they should still work.
The trouble with you, Shev, is you don't say anything until you've saved
up a whole truckload of damned heavy brick arguments and then you dump
them all out and never look at the bleeding body mangled beneath the heap
