Is WWV going away?
The time stamp is regulated by an atomic clock. But a 2019 budget proposal for NIST would close WWV, WWVH in Hawaii and WWVB, which syncs up the time for about 50 million radio-controlled clocks, wristwatches and appliances. So if the WWVB signal goes away, these devices will have to be changed manually.
Can I listen to WWV on the Internet?
NIST has considered streaming the audio from WWV/WWVH via the Internet, but because of audio buffering, the time announcement could be several seconds off and would vary for different users.
Do atomic clocks still work?
The radio controlled clocks (atomic clocks) sold in North America are permanently tuned to receive and synchronize with the National Institute of Standards and Technology atomic clock radio station WWVB in Boulder, Colorado.
How can I listen to WWV?
The audio portions of the WWV and WWVH broadcasts can also be heard by telephone. To hear these broadcasts, dial (303) 499-7111 for WWV (Colorado), and (808) 335-4363 for WWVH (Hawaii). Callers are disconnected after 2 minutes.
How accurate is WWV?
When I listen to WWV or WWVH, how accurate is the time? The time is kept to within less than 0.0001 milliseconds of Coordinated Universal Time (UTC) at the transmitter site, but the signal is delayed as it travels from the radio station to your location.

What is the WWV time?
Voice announcements are made from WWV once every minute. The WWVH announcement occurs first, at about 15 s before the minute. The WWV announcement follows at about 7.5 s before the minute. The announced time is “Coordinated Universal Time” (UTC).
Where is WWV?
Fort Collins
WWV is located near Fort Collins, Colorado, about 100 kilometers north of Denver. The broadcast information includes time announcements, standard time intervals, standard frequencies, UT1 time corrections, a BCD time code, and geophysical alerts.
Is WWV AM or FM?
WWV operates in the high frequency (HF) portion of the radio spectrum. The station radiates 10 000 W on 5 MHz, 10 MHz, and 15 MHz; and 2500 W on 2.5 MHz and 20 MHz. Each frequency is broadcast from a separate transmitter.
What freq is WWV?
The tallest tower, for 2.5 MHz, is about 60 m tall. The shortest tower, for 20 MHz, is about 7.5 m tall….WWV Antenna Coordinates.
