The Radio System That Keeps Us Safe From Extreme Weather Is Under Threat

NOAA Weather Radio needs some serious upgrades.

In March, a group of massive tornadoes struck communities around Des Moines, Iowa. Seven people were killed, including two children under 5. The crisis received attention not only due to its human cost, but also because of delays in emergency wireless communications: Thanks to a broken fiber optic cable at the Dallas-Fort Worth National Weather Service offices, wireless emergency transmissions were switched to an auxiliary satellite system, which all NWS offices use. Overloaded with extreme weather messages from elsewhere in the Midwest, the satellite messaging system found itself backed up just as the Iowa tornadoes reached their peak. This caused anywhere from a two- to nine-minute delay in tornado warning messages—and may have significantly reduced warning time at a moment when seconds count. The issue lasted for several hours as the deadly tornadoes ripped through the state.

NOAA Weather Radio, on the other hand, continued broadcasting effectively during the crisis. According to Bruce Jones, a weather radio expert and meteorologist with Midland Radio Corporation, “because the NWR broadcast comes direct from the National Weather Service local forecast office, those NOAA Weather Radio alerts and warnings were unimpeded and reached folks immediately.”

Often referred to as the “voice” of the National Weather Service, NOAA Weather Radio is a 24/7 public service that broadcasts weather information from more than 1,000 stations across the United States and many of its territories. And while Des Moines was a great success story for NOAA Weather Radio, the service faces mounting issues with aging technology and infrastructure, raising concerns over whether it will be able to continue protecting communities facing extreme weather.

[…]While NOAA Weather Radio has historically been an important, consistent, and life-saving means of emergency communication, it may not be for long. Outdated technology and failed attempts at modernization are threatening the NOAA Weather Radio system and resulting in extended outages for locations at risk. And as the climate crisis intensifies, this important technology is often vulnerable to the weather about which it’s meant to inform.

Interviews with NWS employees about outages reveal many local technical problems that take out communications, sometimes for weeks or months.

[…]Recent congressional action, however, has given new life to the possibility of systemic weather radio modernization. Rep. Stephanie Bice, a Republican from Oklahoma, has proposed the NOAA Weather Radio Modernization Act of 2021, which passed in the House of Representatives in May but has yet to pass in the Senate. From Oklahoma, Bice was well aware of the need for consistent weather communications during natural disasters like tornadoes, which affect her constituents.

The bill would authorize $20 million to expand coverage to the remaining 5 percent of the country without access to NOAA Weather Radio communications, as well as $40 million to modernize its hardware and software, including upgrading communication from copper wires to Internet services. According to Wesley Harkins, a representative from Bice’s office, “this paves the way for future development and provides failsafe options, so NWR is never down for an extended period of time.”

[…]The NWS itself acknowledges the benefits of this legislation. Maureen O’Leary, deputy director of public affairs at the NOAA, told me via email that improvements would include “expanding NWR coverage to rural and underserved communities, national parks, and recreation areas.”[…]

What are your favorite portables in 2022 and why?

I’m traveling this morning and packing up my EDC (everyday carry) bag here int he hotel room.

Last night, I was using the Tecsun PL-330 to do a little band-scanning and it dawned on me that I’ve used this radio along with the Belka DX quite extensively this summer while on an extended family road trip. Even before this trip, both of these radios were in heavy rotation.

I go through phases of using portables–sometimes I’ll dig out a vintage radio and use it for weeks, then I’ll switch it out for a modern rig. I like variety and giving all of my radios a little air time.

I packed the Belka DX and Tecsun PL-330 for our trip because they’re some of the most compact, lightweight radios I own.

I’m curious what radios you’re using now and why–? Please comment!

Interview about Brooklyn pirate radio (Irish Pirate Radio Audio Archive)

Although Irish pirate radio is our main interest, today we explore the lively pirate scene in the Brooklyn area of New York City. The Brooklyn Pirate Radio Sound Map is a fascinating project established by radio producer and audio archivist David Goren and provides interactive maps and historical and contemporary recordings of the many unlicensed stations in Brooklyn.

This is a longer version of an interview by John Walsh with David Goren first featured in Wireless, a series about radio, audio and media on Flirt FM in Galway. It covers the history of pirate radio in Brooklyn and New York generally, attempts to crack down on the unlicensed stations, the role of low-powered FM, the background to the Brooklyn Pirate Radio Sound Map itself and plans for the future. Many thanks to David for taking the time to explain this fantastic project for us. [Read the full article and listen to the interview on the Irish Pirate Radio Audio Archive…]

The Evolution of the Emergency Radio (Radio World)

From AM-only portables to multi-function machines

With the advent of the 9V battery-powered transistor radio in the 1950s, the “Emergency Radio” was born.

Unlike vacuum tube receivers with heavy batteries or unpowered crystal radios, these handheld AM portables were small and simple enough to keep in a drawer. They could then be retrieved whenever man-made or natural disasters knocked out the power, providing listeners with lifeline connections to news, weather and relief information. Continue reading

The Voice of Greece is no longer on shortwave

I suppose I’ve been holding out hope that the Voice of Greece would magically reappear on 9,420 kHz, but they’ve been off the air for 45 days now and we must assume this time it’s for good.

Over the past decade the Voice of Greece seems to have weathered every storm it encountered; even broadcasting for weeks without a license.

We learned in February 2022 that VOG was on the chopping block, then they were given an additional two months on the air, and according to numerous DXers here and on Twitter, the last broadcast seems to have taken place on June 15, 2022.

I certainly haven’t heard them on shortwave since then.

VOG was one of my favorite, reliable sources of music on shortwave and you’ll notice that in many of my radio photos, the dial is tuned to 9,420 kHz because they were such an easy catch here in eastern North America regardless of propagation.

If you miss hearing VOG on shortwave you can, of course, still listen to them online.

I’ve well over one hundred hours of Voice of Greece recordings in my spectrum archives, at the Shortwave Radio Audio Archive, and here on the SWLing Post.

In fact, I’m reminded of one of my favorite VOG listening sessions which I’ll share here from the SWLing Post archives. This post was originally published on November 15, 2013:


Voice of Greece: walking in on a party

I never know what to expect when I tune around on one of my shortwave radios.  Perhaps that’s one of the things I find captivating about the medium; there’s no playlist, no app, no content controls, other than the tuning knob.

Sometimes, I tune to a station, and it’s as though I’ve just opened a door and walked in on a party–one in full swing, with dancing and incredible live music.

That’s exactly what I felt when I tuned to the Voice of Greece last night. I walked in on a party.  And I needed no invitation; I was welcomed there.

Hear it, just as I did, starting right in the middle of this party:

Jerome’s response from Australian Foreign Affairs regarding shortwave to Pacific

Many thanks to SWLing Post contributor, Jerome van der Linden, who shares the following response from from the Australian Foreign Affairs department regarding any future shortwave services to the Pacific. As Jerome notes, the letter “suggests that all is not yet lost, though it’s lacking in commitment.”

Click here to download a PDF of the response.

Quite correct, Jerome. The letter is noncommittal, but at least acknowledges the government will take this under formal review.  I doubt anyone should hold their breath, of course.

Thank you so much for sharing!

Mark Spots an Atlas in “The Rockford Files”

Many thanks to SWLing Post contributor, Mark Hirst, who writes:

Thomas,

I spotted this radio from an episode of the Rockford Files in a story about Russian spies.

According to IMDB, the episode, “A Material Difference” aired in February 1979.

Astronomers detect a radio “heartbeat” billions of light-years from Earth (MIT)

The clear and periodic pattern of fast radio bursts may originate from a distant neutron star.

Astronomers at MIT and universities across Canada and the United States have detected a strange and persistent radio signal from a far-off galaxy that appears to be flashing with surprising regularity.

The signal is classified as a fast radio burst, or FRB — an intensely strong burst of radio waves of unknown astrophysical origin, that typically lasts for a few milliseconds at most. However, this new signal persists for up to three seconds, about 1,000 times longer than the average FRB. Within this window, the team detected bursts of radio waves that repeat every 0.2 seconds in a clear periodic pattern, similar to a beating heart.

The researchers have labeled the signal FRB 20191221A, and it is currently the longest-lasting FRB, with the clearest periodic pattern, detected to date.

The source of the signal lies in a distant galaxy, several billion light-years from Earth. Exactly what that source might be remains a mystery, though astronomers suspect the signal could emanate from either a radio pulsar or a magnetar, both of which are types of neutron stars — extremely dense, rapidly spinning collapsed cores of giant stars.

“There are not many things in the universe that emit strictly periodic signals,” says Daniele Michilli, a postdoc in MIT’s Kavli Institute for Astrophysics and Space Research. “Examples that we know of in our own galaxy are radio pulsars and magnetars, which rotate and produce a beamed emission similar to a lighthouse. And we think this new signal could be a magnetar or pulsar on steroids.”

The team hopes to detect more periodic signals from this source, which could then be used as an astrophysical clock. For instance, the frequency of the bursts, and how they change as the source moves away from Earth, could be used to measure the rate at which the universe is expanding. [Continue reading…]
