I did ask, using the contact email on the NIST page (John Lowe). I'll
forward any replies to the list.
Perhaps we could encourage a more ambitious DCF77-like scheme, if
that's really not in the current plans for WWVB. Especially given the
recent demise of Loran-

I suppose this will help coherent receivers somewhat, but I was
expecting something DCF77-like. A pity.
Thanks for posting your data. You certainly ha
