Once upon a time, Royce Williams <royce () techsolvency com> said:The La Crosse 404-1235UA-SS UltrAtomic (not affiliated, just a fan) tracks DST - and even leap seconds. They have much better reach than previous similar clocks.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. -- <a href="http://www.catb.org/~esr/">Eric S. Raymond</a>
