Sadly, WWVB is damaged. At midnight on April 7, 2024, WWVB's south antenna was disabled due to damage sustained during high winds. WWVB now broadcasts exclusively from the north antenna, at a reduced power of 30kW. This situation is expected to continue "indefinitely", presumably because of a lack of budget for repairs.
This looks like a great candidate for crowd funding.

The US Bill of Rights is copied almost word-for-word from English legislation: https://en.wikipedia.org/wiki/Bill_of_Rights_1689
A copy of the Magna Carta was in the National Archives for a while, and John Locke was a notable influence on founders such as Jefferson. Nihil novi sub sole.
Assuming salt water, a 1024 Kb message should take around 3 hours to transmit.
> I’m not particularly patriotic, but this kind of thing feels particularly American. Maybe that tinge of patriotism is why Americans don't even bother to see if something isn't an American invention - https://en.wikipedia.org/wiki/Time_from_NPL_(MSF) - they'll just claim it anyways since they barely read outside their borders.

Existed everywhere in the world since radios became common. I have an old solar powered Casio g-shock multi-band watch and it gets signals from transmitters located in US, Germany, UK, 2X Japan and China. I have never needed to put watch on time, or change batteries. https://gshock.casio.com/intl/technology/radio/
If for some reason you are a few standard deviations more paranoid about not having the correct time than the average person, they now apparently have models that can get the current time via GPS, time beacon, or Bluetooth from a connected smartphone :)

But calling it "almost copied word-for-word" is not justifiable. On a trivial basis, it's literally not word-for-word in any way. On a more serious basis, there are significant changes in the laws, and enshrining something in an Act which can be changed by future Parliaments is a lot different that enshrining something into a Constitution which is much harder to change.

Sure-- as we've discussed endlessly here: compression and ML are really very close cousins. I never said it was a bad question.
You can even win a prize for that https://en.m.wikipedia.org/wiki/Hutter_Prize .

>The first radio time signal, sent by telegraphic code, was broadcast in September 1903 by the United States Navy. Most sources list Navesink, New Jersey as the site of this broadcast, but the reference clock was located at the United States Naval Observatory (USNO) in Washington, DC. The first regularly scheduled time broadcasts began on August 9, 1904* from the Navy Yard in Boston. By the end of 1905, the Navy had…
There are AM stations broadcasting at only two or three times that frequency that broadcast voice and music.
Perhaps they meant that it is the most practical for small receivers like watches.
BBC R4 Longwave is at 198 kHz (formerly 200 kHz). The transmitter at Droitwich has been broadcasting voice and music since 1934.
