2009年9月24日 · 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.

WWV is a shortwave ("high frequency" or HF) radio station, located near Fort Collins, Colorado. It has broadcast a continuous time signal since 1945, and implements United States government frequency standards, with transmitters operating on 2.5, 5, 10, 15, 20, and 25 MHz. [1] .

2015年5月28日 · WWV and WWVH continuously broadcast a binary coded decimal (BCD) time code on a 100-Hz subcarrier. The time code presents UTC information in serial fashion at a rate of 1 pulse per second. The information carried by the time code includes the current minute, hour, and day of year.

wwv 是一个短波（“高频”或 hf）广播电台，位于科罗拉多州柯林斯堡附近。 它自 1945 年以来一直广播连续时间信号，并实施美国政府频率标准，发射机以 2.5、5、10、15、20 和 25 MHz 运行。

The 10 and 15 MHz frequencies were chosen as harmonics, or multiples of 5 MHz. WWV continues to use all of these frequencies today, as well as another harmonic (20 MHz), and a sub-harmonic (2.5 MHz). The Beltsville area was the home of WWV until December 1966 (although the location name for the broadcast was changed to Greenbelt, Maryland in 1961).

The stations, WWV and WWVB, located near Fort Collins, Colorado, and WWVH, located on the island of Kauai in Hawaii, are the only radio stations located in the United States whose sole purposes are to distribute standard time and frequency information.

The frequencies transmitted by WWV and WVH are held stable to better than 2 2 parts in lo1' at all times. Deviations at WWV are normally less than 1 part in 10l2 from day to day. Incremental frequency adjustments not exceeding 1 part in 10'l are made at WWV as necessary. Frequency adjustments made at WWVH do not exceed 2 parts in loll.

2022年10月16日 · I have a Browning Laboratories RH-10 WWV Standard Frequency Calibrator that I would like to repair. I have not been able to find any info on it, except a paragraph in a 1947 Browning catalog. Anyone familiar with this?
