Looks like somebody finally brought a clock to market that uses the
new-format phase-modulated signal.  Hopefully there'll be more, but with
the WWVB funding threats, I wouldn't be surprised if companies don't
want to invest in any new products that use it.

Interesting - first device I've heard of that uses the new-format
fine modulation, and as NTPsec's tech lead I keep as close an eye on such
developments as anybody.

Before this I had thought that a combination of clock vendors feeling burned by
the modulation change and cheap GPSes entirely killed the market for devices that
can get high-precision time from WWBV.

Anybody know of anything fitting that description that you might want
to deploy in a data center as a Stratum 1? If such a creature exists I shall
contrive to get my lunch hooks on one and write a driver for it.
