Yep, that is how the hot tub time machine does its magic....

I think that's how our hot tub self-sets its time.

I heard a lot lot about it at the time. Their thinking was (IIRC), they were
going to shut off the oldest, least useful of their few platforms that did it.
People whined. The shutdown was postponed.

Sorry, 60 kHz is correct.
This is where I saw that it was on the budget chopping block:

Fake news?

WWVB is solidly supported by the guvmnt. No worries about that signal. I
thought it was 60 KHz. In any event you can pick it up almost everywhere. You
should not have to wait more than a half hour for a clock to lock on. You
might have a bad clock or something in the environment making the signal a bit
weaker.
I was doing a solar panel tracker a few years ago and was wanting to use this
signal to get RTC info. Turns out the only receiver chip manufacturer had
stopped making the chip. Reason was, an antenna, capacitor and perhaps a
transistor is all you need to feed the raw RF directly into a MCU chip. It is
pretty strong.

I am trying to get a cheap “atomic” clock to synchronize, not sure if I have
to wait until night time propagation or what, it is only showing 1 signal bar.
But I did a couple Google searches, and was the federal government actually
planning about a year ago to defund WWV and take it off the air? Seriously?
And that didn’t happen, right, WWVB is still transmitting?
I was a little surprised to realize there is just the one transmitter site in
Colorado, and that WWVB transmits on such a low frequency (50 kHz) and sends 1
bit per second of data.
