WWVH, Radio clock in Kekaha, United States

WWVH broadcasts time and frequency signals from its location at Kokole Point, operating multiple transmitters on different frequencies throughout the Pacific region.

The station began operations in 1948 on Maui before relocating to Kauai in 1971, where it continues its time signal transmission service.

The station employs a female voice announcer for time declarations, distinguishing it from its Colorado counterpart which uses male voice recordings.

Radio controlled clocks receive WWVH digital time codes through integrated antennas, applying mathematical corrections to display accurate local time.

Three cesium atomic clocks maintain precise timing at the facility, with one clock broadcasting while two others serve as comparison and backup systems.
