That signal almost sounds like you could make a clock from it. Like you manually set it and it syncs to beat in the video.

- NobodyNada 5y agoThat's the whole point: https://en.wikipedia.org/wiki/WWV_(radio_station)#Broadcast_format https://en.wikipedia.org/wiki/WWV_(radio_station)#Broadcast_... The "clicks" are second markers, and the low-frequency hum that follows each click encodes a single bit of a binary datastream conveying the current time. If you've ever had an automatic clock in the US, it sets the time by tuning in to WWV and decoding this signal.
- sciurus 5y agoI think most automatic clocks are setting themselves based on WWVB, not WWV. It broadcasts on longwave rather than shortwave and uses a different modulation. https://www.nist.gov/pml/time-and-frequency-division/time-distribution/radio-station-wwvb https://www.nist.gov/pml/time-and-frequency-division/time-di...
- jaywalk 5y agoYou don't even need to manually set it, the date and time is encoded in the tones.
