Broadcaster KUNC reports that a little-known radio station in Fort Collins might one day save the world

An array of radio towers sits behind security fences amid farms and pastures north of Fort Collins. This is home to WWV, the country’s oldest radio call letters. The station’s high-frequency broadcasts can be heard around the globe if you have the right kind of radio.

Now playing: pulsing sounds, every second, followed by an announcement of the exact time.

The station is run by the National Institute of Standards and Technology in Boulder, which is home to the atomic clock. WWV is capable of more than telling time. It could, if need be, save the world.

“Could be,” said Elizabeth Donley, chief of NIST’s Time and Frequency Division. “It’s an important part of our work.”

This year the station conducted communications exercises in coordination with the Department of Defense. Thirty-seven states, National Guard units, emergency management agencies and others participated in simple announcements. They were meant to see how many listeners are out there and how far away they can be reached. The answer: there are thousands of listeners as far away as Australia and New Zealand.

Mark Jensen, a civilian planner with U.S. Northern Command, the military’s homeland security operation in Colorado Springs, called WWV a “most essential asset to our nation.”

Should an emergency arise, volunteers would jump into action. They’re part of a program the military dubs MARS, which stands for Military Auxiliary Radio System. While jokes abound that the operators should not be confused for Martians, their work is serious. It’s doomsday stuff, like responding to the aftermath of a nuclear attack because the associated electromagnetic pulse could wipe out most communications.

FY 2019 NIST budget looks good for time stations

Many thanks to the number of SWLing Post readers who have forwarded this article from the ARRL News that notes the WWV Special Event Station, planned for later this year, is a go. This is great news indeed.

With regards to the FY2019 budget uncertainty surrounding NIST radio stations WWV, WWVH and WWVB, the ARRL notes:

“The NIST budget for WWV, WWVH, and WWVB will remain level for FY 2019.”

As I mentioned in a recent post, this is the feedback I’ve received as well–that the portion of the budget that includes NIST radios station will remain the same as it was last year. Last year, the NIST internally-allocated funds for the stations and it appears it will this will happen again! Brilliant news, indeed.

With that said, I do wonder if the next budget request (which is only a few months away) will include all of the NIST radio stations.

Time will tell…

End of WWV weather information

Many thanks to SWLing Post contributor, Richard Langley, who writes:

As monitored here in NB on 15 MHz today (31 January), WWV ended the National Weather Service Atlantic and Pacific marine high-seas and storm warnings after 19:00 UTC. Before that time, announcements about the ending of the warnings were transmitted during minutes 4 and 7 after the hour with the Atlantic information in minutes 8 and 9 and the Pacific information in minute 10. So, the last storm warnings were during the 18:00 UTC hour. After 19:00 UTC, the announcements in minutes 4 and 7 were discontinued and the storm warnings in minutes 8, 9, and 10 were replaced with an announcement about the ending of the warnings. Presumably, there was a similar transition on WWVH.

Thanks for the report, Richard!

In terms of an overall update about WWV in the 2019 NIST budget, there has been no real news to report. It seems the funding level for the Laboratory Programs (where the radio stations reside) will be funded at the same level as it was in 2018. Of course, NIST can internally-allocate many of their funds as they wish. Many thanks to SWLing Post contributor, Richard Cuff, who’s been keeping an eye on this budget process.

I must admit that I find it interesting WWV, WWVH and WWVB all continued to operate as normal during the Federal Government Shutdown.

Update: Discontinuation of NWS High Seas and Storm Warnings on WWV and WWVH

Many thanks to SWLing Post contributor, Mohamed, who comments with an update about the loss of NWS High Seas and Storm Warnings on WWV and WWVH. Mohamed writes:

The decision to terminate the broadcasts has not been retracted. It has only been delayed to January 31, 2019:

Subject: Discontinuation of NWS High Seas and Storm Warnings
over NIST Time Frequency Broadcasts Effective January 31, 2019

Effective Thursday, January 31, 2019, at 200 pm Eastern Standard Time (EST) or 1800 Coordinated Universal Time (UTC), the NWS will discontinue dissemination of High Seas and Storm Warnings portion of the National Institutes of Science and Technology (NIST) time frequency broadcasts as issued by WWV and WWVH “shortwave” radio covering the Atlantic, Gulf of Mexico and the Pacific.

This service is being terminated because weather information in the current broadcast format does not support frequent enough updates for changes in marine weather and cannot provide enough detail in the allotted window required by mariners to avoid hazardous weather. Additionally, alternative technologies and numerous media outlets that provide weather information in various formats have overtaken the need for providing weather information through the NIST frequency signals.

Other sources of marine weather and high seas alerts and detailed forecasts are available over satellite, telephone, the Internet, Marine Fax, Radio Fax and VHF radio. Currently the NWS, U.S. Coast Guard (USCG), and the U.S. Navy (USN) provide multiple dissemination methods for storm positioning, high sea areas, observations, forecasts, outlooks and warnings for both coastal and oceanic marine zones near the United States using Navigational Telex (NAVTEX), Global Maritime Distress and Safety System (GMDSS) and High Seas SImplex Teletype Over Radio (HFSITOR) in compliance with World Meteorological Organization (WMO) policies and the International Safety of Life at Sea (SOLAS) Convention.

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”

(Source: Marketplace via Richard Cuff)

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.)[…]

If you feel strongly about keeping the atomic clock signals on the air, I urge you to contact your local representatives,and sign this White House petition.
