WWV Centennial Committee Prepares for Trial Run of WW0WWV Special Event

The WWV Centennial Committee reports that it will conduct a trial run of special event station WW0WWV over the August 24/25 weekend.

Radios and antennas began arriving last week, and a tower and beam will be erected, along with several vertical antennas. WW0WWV will be set up adjacent to the WWV transmitter site in Fort Collins, Colorado. WWV turns 100 years old on October 1.

“We’ll be testing band and notch filtering, in an attempt to reign in the extreme RF environment created by WWV and WWVB,” said Dave Swartz, W0DAS, of the Northern Colorado Amateur Radio Club (NCARC).

The club will carry out the special event operation in conjunction with the WWV Amateur Radio Club and the National Institute of Standards and Technology (NIST), which operates WWV/WWVH/WWVB.

The special event site is within 1/3 of a mile of all six WWV transmitters and the 50 kW WWVB transmitter. “On-air tests will start Saturday afternoon, August 24, and run through Sunday, August 25,” Swartz said, adding that organizers will post specific times and frequencies on the WWV Centennial Committee website.

The WWV Centennial special event is set to run from September 28 through October 2, and round-the-clock operation will take place on CW, SSB, and digital modes. Operations will shift among HF bands following typical propagation and will include 160 meters as well as satellites (SO-50, AO-91, and AO-92) and 6-meter meteor scatter.

Up to four stations will be on the air for routine operations. A fifth station will schedule contacts with schools, universities, and museums, as well as conducting unscheduled contacts. The additional station will periodically broadcast an AM carrier from a radio locked with WWV’s 10 MHz signal.

“At this point we have filled our operator’s slots and met equipment goals, but we need more financial resources to cover basic operating expenses, return shipping, and site logistics,” Swartz said. Members of the Amateur Radio industry have contributed equipment, including radios, amplifiers, and antennas.

NIST has announced that it will not be able to open the doors of WWV to the public for the event. “Due to a number of reasons, the scope of the formal celebration will be limited to only 100 invited participants,” the WWV Centennial Committee announced. “WW0WWV will be the main public event for the centennial celebration.”

HF military communication exercise announcements on WWV/WWVH

(Source: ARRL News via Eric WD8RIF)

The US Department of Defense (DOD) plans to start making use of a provisional time slot on WWV and WWVH to announce upcoming HF military communication exercises and how the Amateur Radio community can become involved in them. The announcements will occur at 10 minutes past on WWV and at 50 minutes past on WWVH. WWV and WWVH transmit on 2.5, 5, 10, 15, and 20 MHz.

“DOD’s use of the broadcast time slot on WWV/WWVH will benefit the MARS program’s mission of outreach to the Amateur Radio community,” said US Army Military Auxiliary Radio System (MARS) Program Manager Paul English, WD8DBY. “The actual messages to be broadcast are coordinated by the DOD Headquarters that the MARS program supports.”

The initial announcements are set for the period April 20 – May 3, which coincides with the “Vital Connection” interoperability exercise to be held in Wisconsin. Future time slots will coincide with the Vital Connection exercise Ohio in June; DOD COMEX 19-3 in August, and the DOD COMEX 19-4 in October. Following the proof of concept this year, DOD anticipates making use of the WWV/WWVH broadcast time slot full time, year-round.[…]

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.

FOR IMMEDIATE RELEASE – JANUARY 11, 2019

WWV Centennial Celebration and Special Event Amateur Station September 28 – October 2, 2019

Northern Colorado Amateur Radio Club Logo NCARCThe Northern Colorado Amateur Radio Club (NCARC) will operate a special event amateur radio station in conjunction with the WWV Centennial Celebration, a tribute to radio station WWV, the oldest continuously broadcasting radio station in the world, as it turns 100 years old on October 1, 2019.

Operating from alongside the historic and scientific long wave (WWVB) and short wave (WWV) radio stations, the NCARC effort will use 4 simultaneous operations on a variety of amateur shortwave bands. The goal is to contact as many amateur radio stations in the world as possible during the 5-day operating period, September 28 through October 2, 2019, using a variety of operating modes (Morse code, voice, and data).

The National Institute of Standards and Technology, NIST, (US Dept of Commerce) lists the official 100t?h celebration on their events calendar from 8am until 7pm, October 1, 2019.

NCARC and NIST are working on coordinating the celebration and the special event amateur station. Because of the present shutdown of the US Government, planning and discussions have been put on hold. We look forward to the end of the shutdown, a future press release from NIST, and getting back to work on planning the celebration of this historic event.
NCARC deemed it necessary to issue this press release on our own due to the uncertainty of the length of the shutdown and the need to get this event, at least the special event station, on everyone’s planning calendar as soon as possible.

The exceptional challenge of operating this station will require the help of amateurs and radio clubs throughout Colorado, the surrounding states, and from across the country. Amateurs who are interested in traveling to Fort Collins this fall and taking part in the operations are encouraged to apply starting February 15, 2019. Please see the Operators page on the website.

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.
