WWV & WWVH marine storm warning announcements continue

Many thanks to SWLing Post contributor, Richard Langley, who notes that WWV & WWVH marine storm warning announcements continue despite a recent announcement that they would end.

Richard has been monitoring WWV/WWVH broadcasts and shared the following note earlier this month:

The weather broadcasts (storm information) were still there at 8, 9, and 10 minutes past 0:00 UTC on 1 November on WWV as monitored here in NB. Haven’t had a chance to check them since. Are they actually gone? If so, when were the last ones broadcast. The warning at the 4-minute mark hadn’t been heard for days. I’m wondering if the decision to terminate the broadcasts was reversed.

Yesterday, Richard added the following:

[…]And still there on WWV (and presumably WWVH) on 16 November at 03:08 UTC on 10 MHz. So I guess this conclusively means that the proposal to cancel the broadcasts has been rescinded at least for the time being.

Thanks for sharing this, Richard.

Your observation prompted me to check the NOAA Marine Forecast page. I discovered that it has been updated it since the notice to stop marine forecasts was first announced last month.

Before, it stated that the “end of the high seas warnings [is] scheduled for October 31, 2017.” Either NOAA made the decision to end the the forecasts in 2017 and never followed through, else the individual who posted the announcement mistakenly noted 2017 instead of 2018.

NOAA does not note edit dates on this page, so there’s no way of knowing when the page was updated. Regardless, there is no longer a firm termination date mentioned on the page. Now the National Weather Service simply states:

“the NWS is considering a proposal to discontinue this service.”

So I believe, Richard, you are correct: the NWS has at least temporarily rescinded cancellation of the service.

Thanks for following this development, Richard!

WWV & WWVH to drop NOAA marine storm warning announcements October 31, 2018

Many thanks to SWLing Post contributor, Dave Zantow (N9EWO), who notes that WWV and WWVH are announcing the end of marine storm warning announcements on October 31, 2018.

This morning, I made the following recording of the announcement via WWV 5 MHz at 4 minutes past the hour:

Last year this time NOAA announced the end of the high seas warnings scheduled for October 31, 2017.

Marketplace: “Time may be up for timekeeping radio stations”

The Trump administration wants to shut down two shortwave radio stations that broadcast time signals from the nation’s master clock.

The administration’s budget proposal would eliminate nearly $27 million in funding from the National Institute of Standards and Technology for the two stations. WWV, based in Fort Collins, Colorado, has been transmitting one rock-steady pulse per second for more than 80 years. Its sister station, Hawaii’s WWVH, has been extending the time signal across the Pacific for nearly 70 years. WWV is also the world’s longest continuously-broadcasting radio station. (NIST doesn’t stream the stations online because signals are often delayed as they stream over the internet. 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.)[…]

Synchronizing “atomic” clock’s final tock? Time may no longer be synchronous

Do you have a self-setting “atomic” clock or watch?

Yep, so do I.  A number of them.  In fact, although I’m a tech geek of a sort, I don’t even know how many of my standard, everyday devices––devices I rely on every day––fall into this category…But I may find out soon.

Many of us own self-setting clocks known as “atomic” clocks.  Indeed, a large portion of wall clocks, alarm clocks, and watches, not to mention weather stations, cameras, and potentially a number of other devices, have a built-in receiver that self-calibrates. And all of these sync to a radio station you use more than any other, yet likely have never heard of: NIST Time Signal Station WWVB in Fort Collins, Colorado.

Here’s the issue: WWVB, the atomic clock time signal station that synchronizes time devices, may be shut down next year if a presidential budget request passes as proposed.

WWVB is a time station operated by the National Institute of Standards and Technology (NIST) which derives its time from a system of atomic clocks with frequency uncertainty of less than 1 part in 1012.

Translation: How accurate is this time signal? Crazily, insanely accurate.

And that’s a good thing, as so many of the things we rely on all the time (and often take for granted) rely on it. WWVB provides a continuous 60 kHz carrier wave that, among other things, is employed by self-setting “atomic” clocks used by consumers and industry. WWVB receivers are embedded in so many consumer appliances from cameras to irrigation controllers, these devices depend upon the very accurate timing the station imparts.

Per the NIST:

For huge numbers of people in North America who spend their days in schools, offices, stores, factories and public facilities, the time of their lives comes from clocks controlled by a single radio station that few people have ever heard: WWVB in Ft. Collins, Colorado, operated by PML’s Time and Frequency Division.

According to the latest estimates, there are at least 50 million radio-controlled clocks in operation (and another few million wristwatches) all receiving accurate time from WWVB’s 60 kHz broadcast—and approximately a million new commercial radio-controlled products are sold each year.[…]

Regular readers of the SWLing Post are already aware that the NIST Fiscal Year 2019 Presidential Budget Request includes a call to shutdown WWVB and two shortwave radio NIST time stations, WWV and WWVH.

What happens if WWVB is shut down?

This budget was not approved by Sir Topham Hatt!

If the budget is passed as proposed, after WWVB is closed your atomic clock synchronized devices will no longer be accurate, nor will they automatically be able to toggle the time between Standard to Daylight Savings Time.

They’ll continue to operate, albeit without a self-setting function…thus eventually leading, in the words of Thomas the tank engine’s ubiquitous station master, Sir Topham Hatt, to “confusion and delays.”

And, unfortunately, should the closure occur, there may not even be any public announcement to that effect.

But what does this have to do with us?

These devices are so embedded in our lives here in North America, we scarcely notice them, and many consumers likely assume they’re set by the Internet.

They’re just an overlooked part of our lives that help keep us ticking––quite literally. Until a shutdown happens, we won’t know how many of the millions of devices that we rely upon will be affected. While there may be (arguably lesser) alternatives to this station’s time-setting provision, such as those provided by the Navy and the Internet, we will be without the one we rely upon most for accuracy.

The bottom line…

Something that belongs to all of us, and that we all rely upon to help us keep accurate time, may soon be taken away.  If you feel strongly about keeping the atomic clock signal on the air, I urge you to contact your local representatives,and sign this White House petition.

Otherwise? Time will tell. Or not, as the case may be.

Information from the NIST regarding possible closure WWV radio stations

WWV’s transmitter building in Fort Collins, Colorado (2014)

Regarding the NIST FY2019 budget which includes a request to shutdown WWV, WWVH, and WWVB, many of you have been asking if there has been an update.

We will keep you posted as this budget moves through the process, but in the meantime I’ll share the feedback and links provided by Gail Porter, Public Relations Director for the National Institute of Standards and Technology (NIST).

Ms. Porter writes:

We are proud of the time and frequency services we provide through our radio stations and understand that these services are important to many people.

As you likely know, the President proposes budgets for executive branch agencies and then the Congress considers that request before determining funding levels for each agency and passing an appropriations law to implement a budget for a given year.

The President’s full NIST FY 2019 budget request to the Congress is available at the link below, including a brief description of why the shutdown of the radio stations is proposed: http://www.osec.doc.gov/bmi/budget/FY19CBJ/NIST_and_NTIS_FY2019_President’s_Budget_for_508_comp.pdf. see page NIST-25.

[…]The sentence below, which appears on page NIST 25, is the best description we have available to respond to your question.

“To consolidate and focus work on NIST efforts in quantum science, while maintaining essential core capabilities in measurement science research and measurement dissemination NIST will eliminate efforts that have been replaced by newer technologies, measurement science work that lies outside of NIST’s core mission space, and programs that can no longer be supported due to facility deterioration.”

[…]Here is a link to the NIST Budget Table for the FY2019 Presidential Request.

Also, in case these are of interest, here are links to press releases issued in May and June 2018 by the U.S. House of Representatives and the Senate Committees’ on Appropriations about the FY2019 budget process:



Hope this information is helpful.

Many readers have been asking if all NIST stations are included in these cuts–the answer is yes.

If this budget passes as written, WWV, WWVH, and WWVB will all be closed.

If you value these NIST time stations, I would encourage you to contact your local representatives, and sign this White House petition.

WWVH: “Working at NIST Hawaii”

Many thanks to SWLing Post contributor, Eric McFadden (WD8RIF), who shares a link to the following article from the NIST website authored by Andrew Nobleman, a Grants Management Specialist at NIST. Eric notes that he first discovered this piece from an article in The Spectrum Monitor magazine:

Time on the Beach: Working at NIST Hawaii

The National Institute of Standards and Technology (NIST) has campuses in Maryland, Colorado, South Carolina and Hawaii.

Now, I know what you’re thinking, “Hawaiian campus? How do I get a job at NIST?”

Perhaps calling it a “campus” is a bit of an exaggeration. Ensconced within the U.S. Navy’s Pacific Missile Range Facility on the western Hawaiian island of Kauai (pronounced ka-why-ee), sits one of NIST’s shortwave radio stations, perhaps best known by its call sign, WWVH.

Kauai is a beautiful and remote island with unique climate diversity. In the middle of the island, you have one of the wettest places on Earth, Mount Waialeale (pronounced why-ah-lay-ah-lay), which receives an average of 1,148 centimeters (452 inches) of rain per year. Twenty-five kilometers away, the island’s western coast gets a mere 56 cm (22 inches) of rain per year. This is where you will find the NIST radio station.

WWVH’s main objective is to broadcast Coordinated Universal Time (UTC)—the official time for the entire planet—throughout the Pacific region. Those signals help their audience coordinate, calibrate and synchronize their clocks and equipment, which are vital to telecommunications, internet connections and a whole host of other services.

In addition to accurate time and frequency information, the station also broadcasts weather alerts and space weather reports.

“At the tone …”

From Alaska to Australia and from California to China, if you tune your receiver to WWVH, you’ll hear Jane Barbe speaking to you. If you don’t already know her by name, you may know her voice. It was her recorded voice that in past decades told callers who left their phones off the hook for too long (ask your parents), “If you’d like to make a call, please hang up and try again. If you need help, hang up and then dial your operator.”

Although Barbe died in 2003, her beloved voice lives on.

WWVH actually broadcasts her voice using several frequencies: 2.5, 5, 10 and 15 megahertz. The different frequencies cast a wide net so that users of the broadcast will receive a signal regardless of interference from mountains, atmospheric activity or the time of day. This technique allows users to always have access to the correct time as well as the other information provided by WWVH.

WWVH’s sister station, WWV, broadcasts out of Fort Collins, Colorado. Both stations broadcast on the same frequencies. While WWVH uses Barbe’s voice, WWV uses that of former San Francisco radio host Lee Rodgers, who died in 2013. If the ionospheric conditions are just right, users can hear both stations. In addition to using different voices, WWVH and WWV make their announcements at different time intervals to prevent overlap and confusion.

Why Hawaii?

In 1947, NIST determined it needed to create a second station to supplement WWV and expand its coverage area to the Pacific Rim. The WWVH broadcast station was originally built at Kihei on the Hawaiian island of Maui in 1948. After 20 years, however, the encroaching ocean began damaging the property and equipment. So in 1971, WWVH moved nearly 322 km (200 miles) west to its current home on Kauai. This more-westerly location proved to be ideal, as it allowed the station’s signal to reach even more distant locales.

At one point, there were nine employees at WWVH, including an on-site groundskeeper for the station’s 12 hectares (30 acres). Back then, the station was manned around the clock, but automation has whittled the staff down to four, who are now responsible for all station and land maintenance.

Taken together, engineer Dean Okayama, electrical technician Dean Takamatsu, electrical technician Chris Fujita, and administrative assistant Adela Mae Ochinang, have nearly 100 years of experience operating the facility.

In addition to the staff on location, John Lowe, leader of the Time and Frequency Services Group at NIST’s Boulder, Colorado, campus, manages WWVH and WWV, as well as the long-wave station WWVB, which is also in Fort Collins.

The Pros and Cons of ‘Paradise’

“Oh, you’re going to go out to Hawaii. Lucky you, you get the easy work,” is something Lowe has heard often from his fellow NISTers. He says he seldom explains the intense labor he puts in while on Kauai because people don’t believe him anyway. He comes to the station at least once every two years, and the staff capitalizes on the extra set of hands by saving challenging projects for his visits.

In addition to Lowe’s visits, there is a yearly rotation of staff between WWV and WWVH for continuity purposes in case of an emergency. Fujita says the exchange “usually involves more work at the Kauai location than the Fort Collins location due to shorthandedness on Kauai, but nothing a few beers can’t fix after work.”

The marine environment, while great for beach relaxation, poses a constant challenge for the station. The salty air and heat have literally caused the transmitters to catch fire! One time when that happened, the naval base’s fire department was alerted before the radio station staff was. Unfortunately, the firefighters put out the fire with a dry chemical agent, a corrosive material that rendered the transmitter useless. Shortly after replacing that transmitter, its backup failed. Fujita says, “It feels like we’re chasing transmitters. Once you replace one, it seems like you have to replace another.”

Despite all the staff’s projects and problems, they maintain a 98 percent on-air rate, which, according to Lowe, is amazingly good. Someone is always on call, and it’s all-hands-on-deck during inclement weather, such as the April 14-15, 2018, monster storm that deluged the northern part of the island with 127 cm (50 inches) of rain in 24 hours, but which thankfully spared the area around WWVH. Checks are done daily to ensure the broadcasts are in close agreement with the UTC.

For Okayama, these major responsibilities translate into a passion for the job. If Monday is a holiday, he has to be reminded on Friday not to come in.

For the staff, the work is both fascinating and challenging. But what about all the fun that comes with working right next to a Hawaiian beach?

Surf’s up?

When the clock strikes noon, Fujita packs up his gear and walks down to the beach carrying a surfboard to catch some killer waves. He and Takamatsu have been excitedly eyeing the waves since the moment they walked in that morning.

At least that’s what would happen on TV.

The reality is much more in line with what happens at the other NIST locations: You go to the lunchroom to eat your packed lunch. When Okayama is asked if they spend their lunch break on the beach, he laughs. “It’s like asking someone who lives next to Disneyland if they go every day,” he says. “We don’t eat outside and lay under the palm trees. It’s hot and humid. There are bugs flying around.”

You would expect Lowe to soak up some rays during lunch on his occasional visits, but he is adamant that he runs for the air conditioning when the clock strikes noon. He believes it’s a unique place to work, but the blistering sun isn’t exactly comfortable.

Not to say that no one has ever surfed during lunch. Fujita tried it once, but says, “It’s too cumbersome to go to the beach at lunch. To change and get all your stuff ready, walk to the beach, wax the board, maybe get one or two waves, then come back and shower. It’s cutting it close.”

A Visit from the Boss

In its entire history, WWVH had never had a visit from the director of NIST. But that changed on March 7, 2018, when newly minted NIST director Walter Copan and his wife, who were on a long-planned Hawaiian vacation, took the opportunity to stop by the site.

“The WWVH team are truly NISTers, and they are our ambassadors of metrology on America’s westernmost shores,” says Copan. “The WWVH team was also recognized by a 2008 NIST Bronze Medal, now on display in their entrance hallway, for the development and installation of a new antenna array by the employees themselves. Their work is a true example of the NIST values, which include perseverance and inclusivity.”

It was a great experience to interact with the NIST director, says Ochinang. Copan shared with them his vision for NIST’s future and some interesting things about himself, like the fact that he is a trained opera singer.

When asked if they took advantage of the extra body to get more work done, Fujita says, “We did not subject the NIST director to intense manual labor, no. That wouldn’t be good … especially not on his first visit.” Fujita adds that, since the Copans’ vacation was not a government-sponsored trip, “We would have to reimburse him for work performed.”

I guess they’ll have to wait until Lowe is back in town.

The Kauai Life

Outside of work, life on Kauai is generally more laid back than the mainland or even the larger islands of Hawaii.

Although it sounds great, living in a tropical paradise is not for everyone. Many of those who move to Hawaii succumb to “rock fever,” the claustrophobia that comes from being on a small island.

Fujita and Ochinang were both born on Kauai, and though they left for a few years, coming back was easy. Okayama and Takamatsu are both from Honolulu, which is on the island of Oahu, the third largest Hawaiian island. Still, they seem to have acclimated well to life on a tinier island. Kauai reminds Okayama of a quieter Oahu in the 1960s when his family used to camp peacefully under the stars at the beach. Takamatsu’s father was from Kauai, so in a way, it feels like he’s returned to his roots.

The Kauai lifestyle and close working quarters have created a family atmosphere. They all take care of each other and no one wants to leave. Ochinang has been at WWVH for 35 years and doesn’t plan on going anywhere. “Sometimes people joke around,” she says, “but sorry, this is a good place to work and I’m not retiring anytime soon!”

So, if you want a job there, you’ll have to hang up and try again later.
