WWV

WWV is a radio station in Fort Collins that broadcasts continuous time signals and announcements on frequencies of 2.5, 5, 10, 15, 20, and 25 MHz. This facility transmits precise time information around the clock across multiple shortwave bands.

The National Bureau of Standards founded the station in Washington in 1919 and later relocated it to Maryland. The final move to Colorado occurred in 1966, where it has operated since.

The station uses the call sign WWV since its founding and holds the oldest continuously used call letters for a broadcaster in the United States. Many amateur radio operators and technicians tune in daily to verify their clocks and instruments.

Reception is usually possible throughout North America but can vary depending on time of day and atmospheric conditions. A standard shortwave receiver is sufficient to pick up the broadcasts, and a telephone service offers an alternative for users without radio equipment.

The facility transmits weather alerts and solar activity data alongside time signals, which are important for radio operators. These additional pieces of information help listeners predict disruptions in radio communication and plan accordingly.
