That's dead. What's left as of March 2012 is a plan to move from AM to BPSK,
which is supposed to make it possible to receive the signal farther away
and in areas with more noise and multipath distortion.

There was a trial in early March, any see any results yet?

How will this affect any old devices that use the AM signal method?

Will someone be selling, as I proposed (and shouldda patented) devices that
get the correct time via NTP and broadcast microwatt signals for local area
time sync?

In 1969 the US could put a man on the moon, now teenagers just howl at it. :-(
