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.

1921 NY Railroad Storm could have surpassed intensity of 1859 Carrington Event

Scientific American magazine reports new data suggest the 1921 ‘New York Railroad Storm’ could have surpassed the intensity of the famous Carrington Event of 1859

In a paper published in the journal Space Weather, Jeffrey Love of the U.S. Geological Survey and his colleagues reexamined the intensity of the 1921 event, known as the New York Railroad Storm, in greater detail than ever before. Although different measures of intensity exist, geomagnetic storms are often rated on an index called disturbance storm time (Dst)—a way of gauging global magnetic activity by averaging out values for the strength of Earth’s magnetic field measured at multiple locations. Our planet’s baseline Dst level is about –20 nanoteslas (nT), with a “superstorm” condition defined as occurring when levels fall below –250 nT.

Studies of the very limited magnetic data from the Carrington Event peg its intensity at anywhere from –850 to –1,050 nT. According to Love’s study, the 1921 storm, however, came in at about –907 nT. “The 1921 storm could have been more intense than the 1859 storm,” Love says. “Prior to our paper, [the 1921 storm] was understood to be intense, but how intense wasn’t really clear.”

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.”

Lavina Shaw: History of a Canadian railway brass pounder

Many thanks to SWLing Post contributor, Eric McFadden (WD8RIF) who shares the following post by James Wade (WB8SIW) from the QRZ.com forums:

The CBC recently interviewed Lavina Shaw, Past International President of the Morse Telegraph Club. In this biographical documentary, Lavina talks about her experiences working as a railroad and commercial telegrapher as well as her experiences as a woman working in a man’s world. Like many telegraphers of her era, Lavina had a front-row seat to history.

In addition to railroad and commercial operations (telegrams, cablegrams), the telegraph was widely used in a variety of applications such as stock brokerage operations, commodities and board of trade work, press operations, and so forth. Even the telephone company used Morse telegraphy extensively for its internal operations well into the post war era.

Radio amateurs in general, and CW operators in particular, will undoubtedly find this video interesting, not just for the human interest content, but for its insights into the antecedents of radiotelegraphy.

The Morse Telegraph Club is a non-profit historical and educational association dedicated to preserving the history and traditions of telegraphy and the telegraph industry. MTC members and chapters demonstrate telegraphy at historical events, design and construct historically correct museum exhibits and conduct presentations on the history of telegraphy. MTC also publishes an excellent quarterly journal entitled “Dots and Dashes, which includes articles on telegraph history and first-person accounts of telegraph industry employees.

Thanks, Eric, for sharing this fascinating piece about Lavina Shaw!

Radio Caroline North via Ross Revenge for Easter fundraiser

(Source: Southgate ARC via Eric McFadden)

Join us this Easter, our 55th Birthday, for our Annual Fundraiser.

We will be broadcasting Radio Caroline North live from our radio ship, Ross Revenge, anchored in the estuary of the River Blackwater, from 9:00 am on Easter Friday until 2:00 pm on Easter Monday (all UK times).

You will be able to hear us on 1368 AM (courtesy of Manx Radio) in the north west of the UK (and parts of Ireland) and on our own 648 AM frequency in the south east, and also round the world online at www.radiocaroline.co.uk and on our mobile app.

In addition, you will be able to hear our regular Radio Caroline album format and Radio Caroline Flashback programmes on their normal channels, when they are not carrying the Radio Caroline North programmes.

It’s been quite a year, with our 648 AM and London DAB transmissions both building a substantial new audience for Radio Caroline.

However, with each expansion, our annual running costs increase substantially. And there’s lots more we would like to do.

This year, we have created a stylish Radio Caroline Bell teeshirt, based on a design that  was originally used for the Radio Caroline Roadshows.

Starting on Easter Friday, and ending at midnight UK time on Easter Monday, if you are able to make a one off donation of 25 Pounds or more, or join the Radio Caroline Support Group (for a minimum monthly donation of 7.50 Pounds, cancellable at any time), we will send you your Retro Radio Caroline Bell teeshirt.

And remember, donations of any amount will always be gratefully received.

The donation button will go live on our website early on Easter Friday.

After deducting the cost of the teeshirt, we are planning to use approximately one half of your donations to maintain and expand our broadcast operations, and the other half for the maintenance and upkeep of Ross Revenge.

Happy Easter!
