I agree with above commenter -- must have been some really exceptional ionosphere conditions or something! By the way, what's the latest on the retirement/phasing out of these time signal stations? I was under the impression from years ago that they were on the way out / being defunded with some kind of decade-long timescale (in favor of GPS).

There was a 2019 NIST budget proposal to shut down WWV, WWVB, and WWVH, but this was reversed in the final budget. The Wikipedia page has some details. See the last paragraph under "Time signal transmissions", especially the two footnotes. https://en.wikipedia.org/wiki/WWV_(radio_station) https://en.wikipedia.org/wiki/WWV_(radio_station) That said, no one knows what the future holds.

> I was under the impression from years ago that they were on the way out / being defunded with some kind of decade-long timescale (in favor of GPS). There's actually an effort to get more systems in addition to GPS going, as it is a SPoF. eLoran is one option, and has an advantage of actually being in production in other countries already. There are others. The US DoT published a study in January 2021 (PDF): * https://www.transportation.gov/sites/dot.gov/files/2021-01/FY%2718%20NDAA%20Section%201606%20DOT%20Report%20to%20Congress_Combinedv2_January%202021.pdf https://www.transportation.gov/sites/dot.gov/files/2021-01/F... So I doubt reducing time signals generally is really on the menu.

Owners of casio waveceptor watches will be very sad if these stations are ever decommed.

  I already am. Random interference will change the time on mine constantly.

  I replaced the clock movement on two analog clocks at home to sync with WWVB. It's pretty nice not having to set them up at all, and replacing the battery (not even once a year) is almost fun.
