Tonight propagation was pretty good into my area, while listening to WWV for some testing, I heard a faint female voice buried under the WWV ticks. It announces the time just before the WWV male voice announces his. Does anyone know which station is this female voice originate from?

Thanks

That is WWVH, located at Kekaha, Hawaii. Here is a short bit of information from the NIST Web site (http://tf.nist.gov/timefreq/stations/wwvh.htm):

"NIST radio station WWVH broadcasts time and frequency information 24 hours per day, 7 days per week to listeners worldwide. The station is located on the Island of Kauai, Hawaii on a 12 hectare (30 acre) site near Kekaha at Kokole Point. The information broadcast by WWVH includes time announcements, standard time intervals, standard frequencies, UT1 time corrections, a BCD time code, geophysical alerts, marine storm warnings, and Global Positioning System (GPS) status reports.

Broadcast Frequencies

WWVH operates in the high frequency (HF) portion of the radio spectrum and radiates 10,000 W on 5, 10, and 15 MHz, and 5000 W on 2.5 MHz. Each frequency is broadcast from a separate transmitter. Although each frequency carries the same information, multiple frequencies are used because the quality of HF reception depends on many factors such as location, time of year, time of day, the frequency being used, and atmospheric and ionospheric propagation conditions. The variety of frequencies makes it likely that at least one frequency will be usable at all times."

With a male voice on WWV and a female voice on WWVH it makes it pretty easy to identify which one (or both, as you found out) are being heard. They also stagger the voice announcements (as much as possible anyway) to prevent the announcements from being harder to understand if both signals are strong and both were to talk at the same time.

Although this is done by a government agency, they appeared to have thought things out on these transmissions.

As an aside as long as propagation allows you might find some pirates on 10MHz USB and in the guard frequencies either side. When you hear WWVH usually the Pacific path is open to the Far East, fishing boats are the usual suspects.

That was well done by the National Bureau of Standards long before they became the National Institute of Standards and Technology or the ISO was a gleam in a boffin's eye. Remember we're not dealing with the FCC here. (;->)
