Is WWV still transmitting?
WWV, based in Fort Collins, Colorado, has been transmitting one rock-steady pulse per second for more than 80 years. But you can hear the stations by calling (303) 499-7111 for WWV or (808) 335-4363 for WWVH . There are also online recordings of the stations’ gentle announcements.)
What mode is WWV?
WWV Broadcasts National Institute of Standards and Technology (NIST) time and frequency signals from a location near Fort Collins, Colorado. WWV uses a male voice. The transmission mode is DSB AM.
What frequency does WWV transmit on?
Broadcast Frequencies 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.
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.
When did WWV move to Fort Collins?
WWV moved to its present location near Fort Collins on December 1, 1966, enabling better reception of its signal throughout the continental United States. WWVB signed on in that location three years earlier.

What is WWV and WWVH?
WWVH is the Pacific sister station to WWV, and has a similar broadcast format. WWVH uses a female voice (Jane Barbe) to distinguish itself from WWV, which uses a male voice. WWVH time signals can also be accessed by telephone.
How accurate is Wwvb?
For example, WWVB broadcasts a continuous 60 kHz sine wave signal, but drops the carrier power by about 98% (17 dB) every second, restoring it to full power a fraction of a second later.
Why is it called WWV?
The radio broadcasting craze started after World War I. NIST, then known as the National Bureau of Standards (NBS), got the call letters WWV for its experimental radio transmitter on Oct. 1, 1919. WWV began broadcasting in May 1920 from Washington, D.C., at a frequency of 600 kilohertz.
What is the purpose of WWV?
WWVB sets clocks by broadcasting a digital time code on a frequency of 60 kHz. The time code bits are sent by raising and lowering the power of the signal.

What is the difference between WWV and WWVH?
Discrimination between the two stations may be accomplished as WWV uses a male announcer for announcement of time, while WWVH uses a female announcer. 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).
