NIST FY2019 budget includes request to shutdown WWV, WWVH, and WWVB

Many thanks to a number of SWLing Post readers who have pointed out the NIST 2019 Presidential Budget request which has now been posted online and includes a desired reduction of:

“$6.3 million supporting fundamental measurement dissemination, including the shutdown of NIST radio stations in Colorado and Hawaii

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

I’ve always considered WWV and WWVH to be the heartbeat of the shortwaves here in North America–a constant, timely companion and brilliant gauge of HF propagation. Indeed, on a personal note, WWV was actually the first station I ever remember hearing on shortwave.

I assumed both stations would be some of the last to go silent on the shortwaves.

No doubt, I find this budget request very disappointing. Let’s hope, somehow, this does not come to fruition. We will certainly post any/all updates here on the SWLing Post. Follow the tag: NIST

UPDATE: I’ve received a number of questions about Fort Collins-based station WWVB and if it would also be included in the closures. As the budget states, it includes: “the shutdown of NIST radio stations in Colorado and Hawaii.” At the budget’s current iteration, this implies all NIST radios stations including WWVB.

I’ve pointed out WWV and WWVH in particular as they’re the shortwave time stations of the NIST. WWVB, on the other hand, provides a continuous 60 kHz carrier wave that, among other things, is used by self-setting “atomic” clocks used by consumers and industry.

I’ve amended the title of this article to reflect WWVB’s inclusion in the budget cuts.

Sound Designer Ben Burtt Reveals Radio’s Influence in Star Wars films

Today is popularly known as Star Wars Day––and I’m reminded of one of my favorite posts, featuring Star Wars sound designer, Ben Burtt, who to my surprise, contacted me to answer a question I published here on the SWLing Post.  Once again, here it is. Enjoy!  And “May the fourth be with you!”


StarWars-LogoSWLing Post readers may remember a post I published in which I believed I’d identified a familiar shortwave time signal station in the Battle of Hoth scene from The Empire Strikes Back.

To recap, here’s the scene in The Empire Strikes back–listen carefully:

Now listen to the recording of Canadian Time Station CHU I made recently–note the tone and duration of the data pips:

Upon hearing this, I went so far as to muse that the Star Wars sound designer might be a radio listener. I asked our readers if anyone could confirm this–?

Well, we’ve got our answer!  I’m truly indebted to an SWLing Post reader who passed my post along to his friend, Ben, who could provide this definitive response:

“This is Ben Burtt, sound designer of the Star Wars films. A friend sent me a link to this blog thinking I would like to comment.

Ben and old recorders

“The answer is yes, I have always been a ham radio enthusiast.”

“My grandfather, Harold Burtt, operated W8CD out of his home in Columbus, Ohio 1930s-1960s. I was enthralled as a kid listening to the sounds on his receiver. I heard alien worlds and cosmic ‘voices.’

“So not only did I record his radio, but continued to do so on the Star Wars series and Star Trek as well.

My memory of the Hoth transmission was that it was WWV but it could have been CHU since I was recording all that interested me on the dial.”

Terrific! Thank you, Ben, for taking the time to respond. As I said, you’ve certainly started off this radio enthusiast’s year on the right wavelength…no doubt some of our readers will agree.

Indeed, the powerful sonic experience of the Star Wars and Star Trek films has, in my estimation, helped shape many of us into the radio/sound enthusiasts we’ve become–myself certainly included. Thank you, Ben, for this!  You’ve sharpened my ear to a greater appreciation of sound, especially filmic sound, and your work in particular.    

For readers who are less familiar with Ben Burtt’s work, check out his Wikipedia page and IMDB profile–you’ll find he’s been the sound designer on numerous influential films including the recently released Star Wars: The Force Awakens.

A special thanks to Ben Burtt for sharing these wonderful photos and kindly giving me permission to use them here on the SWLing Post.  I must say, considering my love of radio in the thirties, I especially like that photo of Harold Burtt (W8CD) in his shack.

India to employ long wave radio technology

Two towers, about three times the height of the Qutab Minar, are likely to be erected at as-yet-undecided locations in the country for disseminating Indian Standard Time.

The National Physical Laboratory, an organisation charged with ensuring that Indian time stays accurate, has signed an agreement with IFR Information Dissemination Services (IFR) Ltd., which will set up the towers and employ long wave radio (LWR) technology to purvey this time to a range of users, from phone companies to railway stations. Customers will need a microchip that can be embedded into everything, from wall-clocks to servers.

“Long range radiowaves from the towers can be reliably transmitted even during major disasters. Other than time, information such as a tsunami warning or weather warnings can also be sent,” Pawan Kumar Kasera, director, IFR, said at a press conference. IFR is affiliated to the Germany-based EFR GmbH, which is in the business of providing similar services in Germany.

The company now requires a plethora of permissions from other government departments to host these towers, each with a range of 1,000 km, and an investment of about Rs. 600 crore, which it will raise privately.

The NPL would help IFR keep their caesium clocks (located in the tower) calibrated but wouldn’t be involved in setting up the infrastructure related to time dissemination. Last year, the Council of Scientific and Industrial Research-body had tied up with the Indian Space Research Organisation to provide time-related services for its satellites. “The advantage of LWR is that the waves travel close to the ground and so can reach out to far-flung locations, even to submarines. We’d advertised through newspapers asking private players to help us disseminate NPL-time to the public. Five companies approached us and we’ve selected IFR,” Dinesh Aswal, director, NPL, told The Hindu .

WWV Scheduled Broadcast Outage February 21 & 22

(Source: WWV)

NOTICE OF SCHEDULED BROADCAST OUTAGE:

Due to an electrical upgrade, Radio Station WWV will be off the air on all frequencies on February 21 and 22, 2017. The outages will occur between 7:00 AM and 5:00 PM Mountain Standard Time, and will not exceed 8 hours duration each day.

I’m not sure that I’ll be around to do this, but it might be fun trying to record the moment the outage occurs and the moment it recommences.

Leap second added to 2016

(Source: NPR)

Here’s a timely reminder for all you would-be revelers out there: Be careful with your countdowns this New Year’s Eve. There will be a little extra time to bask in the glow of a retreating 2016 — or curse its name, as the case may be.

Whatever your inclination may be, one thing is certain: Before the year is out, the world’s foremost authority on time will be adding one more second to the clock.

In a bulletin released this summer, the International Earth Rotation and Reference Systems Service, or IERS, said it would be necessary to introduce a “leap second” at the end of December. Timekeepers use this added second much as leap years are used — to bring the world’s atomic clocks in sync with the Earth’s own distinctive rhythm, which in this case is determined by its rotation.

This leap second isn’t the first. Since 1971, the world has added leap seconds with some regularity — typically every two to three years — and the latest leap second was added only last year, in June.

Continue reading at NPR…

Last year, I recorded the 2015 Leap Second via WWV–click here to read that post. Though such a subtle change, it is fun to hear that extra second added. I plan to record the full 31 meter band New Year’s Eve–hopefully, I’ll also catch the 10,000 kHz WWV Leap Second!

Paul discovers Firedrake in an unexpected place

Many thanks to SWLing Post contributor, Paul Walker, who writes:

From time to time, I get some interesting shortwave catches here in Alaska.

Sometimes on 10 MHz, I get WWV. Sometimes I get WWVH. Sometimes I get BPM China. And from time to time, I’ve heard all three at once.

Well this clip is something a bit different…

From April 20, 2016 at 1707 UTC here is my Tecsun PL880 connected to a 225 foot long wire with audio set at 3.5 kHz while tuned to 10,000 kHz (10 MHz).

This time, I am hearing WWVH Hawaii and […] the Chinese Firedrake jammer. What’s happening is Firedrake is jamming the Sound of Hope on 10005 kHz and the signal is so wide, it’s [competing with] WWVH.

I am making no adjustments to the dial tuning or audio settings as this happens. Listen to how things fade in and out.
