Taiwan radio enthusiasts tune in as Chinese, U.S. warplanes crowd sensitive skies (Reuters)

SYUHAI, Taiwan, May 24 (Reuters) – Shortly after dawn on a southern Taiwanese beach, Robin Hsu’s iPhone pings with the first radio message of the day from Taiwan’s air force as it warns away Chinese aircraft.

“Attention!” a voice says on the radio, speaking in Mandarin to a Chinese military plane flying at an altitude of 3,500 meters. “You have entered our southwestern air defence identification zone and are jeopardising aviation safety. Turn around and leave immediately.”

Taiwan, which China claims as its own territory, has complained for years of repeated Chinese air force missions into its air defence identification zone (ADIZ), which is not territorial airspace but a broader area it monitors for threats.

Although Taiwan’s Defence Ministry details these almost-daily incursions on its website, including maps outlining the activity, a band of Taiwanese radio enthusiasts like Hsu has been tuning in to related radio traffic and publishing the recordings online. [Continue reading…]

ABC’s oldest medium, radio, still vital in a world of streaming and podcasts (ABC News)

Thelma Denny doesn’t know life without the ABC.

Now 84, the resident of Apple Tree Creek near Bundaberg, was born six years after radio announcer Conrad Charlton announced to the country: “This is the Australian Broadcasting Commission.”

As a young girl, Thelma remembers her father “always had the radio on”, especially for the cricket or her mother’s favourite long-running radio drama Blue Hills.

These days the radio is her comfort and companion, especially since her husband, Ronald, died in 2016, two days after their 58th wedding anniversary.

Still living independently, the great-grandmother loves nothing more than to unwind with Phillip Adams talking from her bedside table each weeknight as she falls asleep.

But ABC radio is also her lifeline, so when her radio went on the blink, Thelma was at a loss.

“That’s been the problem, I can’t get an update on the weather,” she said.

“If there is a storm on, I have to turn off the television and the computer which has the weather bureau site.”

In times of emergency, it’s recommended battery-powered radios are part of home emergency kits, with power outages, poor internet and phone coverage meaning many regional areas’ only source of information is the radio. [Continue reading…]

Funklust is back on air with a boost (Red Tech)

ERLANGEN, Germany — Funklust, a German Digital Radio Mondiale shortwave station that began broadcasting in 2003, has returned to the air after undergoing extensive improvements.

Funklust is the student radio station of Friedrich-Alexander-Universität Erlangen-Nürnberg in Germany. The station is a partnership between the university and the nearby Fraunhofer Institute for Integrated Circuits.

Friedrich-Alexander-Universität describes itself as “one of the largest research universities in Germany,” while Fraunhofer bills itself as “Europe’s largest application-oriented research organization.”

A joint effort

The students produce the program content and schedule. Fraunhofer handles the technical side of Funklust. Programming is mostly non-stop music, but it does carry a few external programs, such as Radio Goethe. The station was originally on the air as BiteXpress in 2003 and switched to Funklust several years later.

Fraunhofer recently updated the station’s equipment, and Funklust returned to shortwave in October 2021 after going off air in 2018.

The original transmitter was a 1,000 watt Telefunken S2525 DRM-capable transmitter. Fraunhofer replaced it with a new RFmondial 250 watt transmitter, which feeds the signal into a vertical lambda/four-monopole antenna mounted on a concrete mast at a height of 58 meters (just over 190 ft.)

A shortwave broadcast station typically broadcasts an analog signal using amplitude modulation. A single transmitter would only carry a single audio service, nothing more. By contrast, a DRM transmitter offers additional signal options, including the carrying of transmission information and other data. [Continue reading…]

Public Media and Direct Democracy (Public Media Alliance)

By Gilles Marchand, Director General of SRG SSR

“The fate of democracies will depend on their ability to produce and disseminate quality information.”

This article was originally published in Le Monde on 15 April 2022.

The debate surrounding funding for public service broadcasting is wide open and has, in particular, been covered by this newspaper. The French Presidential election campaigns have provided various different proposals, ranging from replacing the licence fee with an allocated budget to privatising the entire sector.

Clearly, this is a sensitive issue. It concerns a fragile ecosystem that has been disrupted by international pressure from streaming platforms and turned upside down by social media. It also fascinates politicians who enjoy the rush of being regulators, clients and media consumers all at the same time. Switzerland, with its direct democracy model, is an interesting testing ground as the citizens of this small multilingual and multicultural federal state get to decide regularly on the fate of the country’s public service with a vote.

Switzerland: a testing ground

As such, SRG SSR (Swiss Broadcasting Corporation) is the only public service provider in Europe to have come face to face with universal suffrage. In 2018, a referendum on abolishing all forms of public funding for it sparked fierce, unprecedented debate surrounding SRG SSR’s radio, TV and online programmes. The European broadcasting industry watched on in amazement as the battle lines were drawn between those for and against the existence of public service media. In the end, following a lot of intense campaigning, there was a convincing outcome at the polls as over 70% came out in favour of this public service and a licence fee which at the time amounted to around 360 euros a year per household!

Russian radio voices sow fear in Ukraine war zone (France24)

Lysychansk (Ukraine) (AFP) – The portable radio in the dark cellar of the rocket-damaged kindergarten was transmitting news in Russian over whistling airwaves about the Kremlin’s military triumphs in Ukraine.

The six frightened women and lone man cowering in the heart of the east Ukrainian war zone had no idea whether to believe the monotone voice — or who was actually patrolling the streets of the besieged city of Lysychansk above their heads.

All they knew was that their building was hit a few days earlier by a Grad volley that left the tail end of one of the unexploded rockets sticking out of the pavement at a sharp angle just steps from the back door.

Their feverish fears vacillated between the idea that their shelter’s lone entrance might get blocked by falling debris and that the Kremlin’s forces might come knocking unannounced.

“The Russians on the radio just said that they have captured Bakhmut. Is that true?” Natalia Georgiyevna anxiously asked about a city 30 miles (50 kilometres) to the southwest that remains under full Ukrainian control. [Continue reading…]

Thoughts on Shortwave’s Heritage and Future (Radio World)

In this guest commentary, DRM’s Ruxandra Obreja dives back in to the shortwave debate

Radio World’s “Guest Commentaries” section provides a platform for industry thought leaders and other readers to share their perspective on radio news, technological trends and more. If you’d like to contribute a commentary, or reply to an already published piece, send a submission to [email protected].

Below is perspective from Ruxandra Obreja, consortium chairman of Digital Radio Mondiale (DRM), in response to the commentary “Shortwave Revival a Non-Starter? The Authors Respond.” Her commentaries appear regularly at radioworld.com.

Seldom have we seen so much passion and polarizing views as in the recent articles for and against shortwave. From “it’s dead and gone” to “this is the revival,” all shades of opinion concerning this simple and all-encompassing platform have been expressed vigorously.

Shortwave Has a Pedigree

Shortwave, currently used for large-area, regional and international coverage in the developing world, certainly registered a decline in the past two decades (but it never died, as you can see here). This loss of pre-eminence in the developed world after the Cold War is not surprising. The platforms available nowadays, in the so called “global village,” include “basic” internet connections (browsing, emails, messaging apps of any type), to the prolific social media products (Facebook, Instagram, Twitter, Reddit), as well as video, radio and TV apps, satellites, mobiles give the impression that the whole world is truly connected!

At least this is the view from Washington, London, or Berlin. But there are the same proportion of people in Europe and America with everyday internet access as there are in Africa with no way to access to it. In such regions, shortwave and mediumwave radio remains essential for many, one of only a few reliable means to receive communication.

Since the arrival of AM and FM some seventy years ago, the invention of at least three largely recognized digital broadcasting systems (DRM, DAB/DAB+ and HD) is the most notable radio development. Digital Radio Mondiale — the DRM open-source global standard — is the latest and most advanced of the three systems, but the only one that can digitize radio in all frequency bands and the only digital option for shortwave.

Closing shortwave transmitters and then trying to restart them presents a huge time, effort and financial challenge. However, nowadays, broadcasters can often buy shortwave transmission hours, in digital, too, from third party distributors, and do not necessarily need to rebuild a comprehensive infrastructure.

Russia to close CBC/Radio-Canada Moscow bureau (Public Media Alliance)

The closure of the public media organisation’s bureau demonstrates further curtailment of independent and free press in Russia.

CBC/Radio-Canada – the only Canadian news organisation with a permanent presence in Russia – has been ordered by the Kremlin to close its bureau. After more than 44 years of reporting from Moscow, CBC/Radio-Canada staff have been told to leave the country. However, Vladimir Proskuryakov, deputy chief of mission of the Russian Embassy to Canada, said they would not be rushed out of the country. He told the CBC News the staff would not be forced to leave in “less than three weeks.”

CBC/Radio-Canada currently has 10 employees working in Moscow, including locally hired staff.

The move is retaliatory and comes two months after the Canadian telecommunications regulator, CRTC, banned Russian state TV stations RT and RT France from broadcasting in Canada. [Continue reading…]

Radio station elevates voices of Hungary’s Roma minority (AP News)

BUDAPEST, Hungary (AP) — Intellectuals, broadcasters and cultural figures from Hungary’s Roma community are using the airwaves to reframe narratives and elevate the voices of the country’s largest minority group.

Radio Dikh — a Romani word that means “to see” — has broadcast since January on FM radio in Hungary’s capital, Budapest. Its 11 programs focus on Roma music, culture and the issues faced by their community, and aim to recast the way the often disadvantaged minority group is perceived by broader society.

“Roma people in general don’t have enough representation in mainstream media … and even if they do, it’s oftentimes not showing the right picture or the picture that is true to the Roma community,” said Bettina Pocsai, co-host of a show that focuses on social issues.

Radio Dikh, she said, aims to “give voice to Roma people and make sure that our voice is also present in the media and that it shows a picture that we are satisfied with.”

Some estimates suggest that Roma in Hungary number nearly 1 million, or around 10% of the population. Like their counterparts throughout Europe, many of Hungary’s Roma are often the subjects of social and economic exclusion, and face discrimination, segregation and poverty.

Adding to their marginalization are stereotypes about Roma roles in society, where they are often associated with their traditional occupations as musicians, dancers, traders and craftspeople that go back centuries. [Continue reading…]

BBC World Service: Licence fee spending to be cut £30m

3 Replies

Many thanks to SWLing Post contributor, Jonathan Marks, who notes that BBC Director General Tim Davie announced a digital strategy along with a number cuts following the BBC licence fee settlement. This was all outlined in his “A digital-first BBC“ speech to staff this afternoon.

I’ve pasted the full copy of his speech below, but regarding the BBC World Service, here is an excerpt: 

“The Government’s commitment to extend its £94m annual funding for the World Service for a further three years is very welcome. But UK licence fee funding for the World Service, which has been around £254m in recent years, is now running at over £290m including World News – a level that is unsustainable following the licence fee settlement.

We will set out plans in the coming weeks for how we will initially reduce licence fee spending on the World Service by around £30m by the start of 2023/24, while protecting the full breadth of languages.

At the same time, our strategic review will identify the right longer-term model for a digital-first World Service and lay out a strong case for more investment from government over the coming years. This case for a strengthened World Service is compelling but we can only expect UK licence fee payers to fund so much.”

In addition, they hope to save £500m annually by cutting services such as Radio 4 Extra, Radio 4’s Long Wave service, and Radio 5 Live’s mediumwave transmitter network.

The Director General’s speech to staff, of course, primarily focused on being a world-class digital and on-demand provider. 

Here’s the full text of the speech via the BBC Media Centre:

A digital-first BBC

BBC Director-General Tim Davie’s speech to staff on 26 May 2022

Published: 26 May 2022

Good afternoon everybody.

Today, in our centenary year, I want to set out a vision of how we keep the BBC relevant and offer value to all audiences in an on-demand age.

I will cover three things: the pressing need to build a digital-first BBC; how we spend our money now that we have the certainty of public funding for six years; and how we keep reforming the way we work. Continue reading →

Spotlight on Broadcast Tower Climbers in New Documentary (Radio World)

NATE, in collaboration with Storybuilt Media, has created a feature-length documentary titled “Vertical Freedom,” which highlights the professional and personal lives of six communications infrastructure workers in the United States.

Throughout the film, these cellular and broadcast tower climbers share what compels and excites them about their line of work. Plus, how to overcome every-day danger in order to connect us all.

Ky Nguyen is just one of the climbers featured in the film. He has worked with RIO Steel and Tower out of Alvarado, Texas for the last 10 years.

After the Great Recession, Nguyen wanted to move away from his job in construction and — while he is skilled at his craft now — he was initially hired onto the tower communication service’s team with zero experience.

“I started as a climber and then just kept working my way up,” he said. “Then I became foreman and began project managing. I’m one of those types of guys where, if you want it done a certain way, you have to be with them, showing them, leading by example – so I’m climbing every day.” [Continue reading…]

Repairing the Sony ICF SW1 Receiver — Used for Numbers Station Reception? Why no replacement for C-625? (Soldersmoke)

Ten years ago, my friend John gave me this tiny Sony receiver. It wasn’t working. I tried to fix it but quickly discovered that the tiny size of the device made repair difficult. All you needed to do was to swap out some leaking electrolytics, but they are surface mount electrolytics — replacing them is not for the faint of heart. Kits are available, but again, this is not easy.

In 2020 I got one of the kits, but didn’t try to use it until yesterday. It only supplied six of the electrolytics. In the video above, they discuss replacing seven electrolytics, including the one that seems to be placed in the round black holder. C-625. Why didn’t my kit include a replacement for that one? Could it be that this capacitor was not one of the leaky SMD caps?

Replacing these caps really wasn’t easy. At one point I inadvertently removed not just the bad cap, but also a nearby surface mount resistor. Luckily the schematic showed it to be 0 ohms. That was easily replaced. I lifted one of the pads on one of the other caps — I just slid it back into place and hoped for the best. [Continue reading at Soldersmoke…]

FCC Report 5/22: FCC To Consider Franken-FM Status And Whether To Expand Radio Service On Channel 6 (Radio Insight)

The FCC has introduced a proposal for rulemaking to determine whether to permanently approve the use the spectrum of television channel 6 for analog radio service on 87.75 MHz and will vote on whether to proceed with it at its June meeting.

In July 2021, all of the remaining analog low-power television stations were required to convert to digital, which would then lead to thirteen of them resuming analog audio transmission within their ATSC 3 broadcasts on an experimental basis. The rulemaking proposal seeks comments whether FM on channel 6 operations server the public interest and should be authorized to continue, whether they should be authorized as ancillary or supplementary services and if so subject to a new rule that permits their operation subject the certain technical and operational requirements, whether they can limit future channel 6 FM operations to those stations with active STAs, whether to consider a proposal to license additional non-commercials FMs on 82-88 MHz in areas where no television stations are operating, and whether to eliminate or revise the distance separation rules between television stations on channel 6 and radio licenses in the non-commercial band.

The full proposal can be read at this link.

The petition by Educational Media Foundation and antenna manufacturers Dielectric, Jampro Antennas, Radio Frequency Systems, and Shively Labs to allow FM antenna directional pattern verification by computer modeling was approved at the FCC’s monthly open meeting.

The improvised Led Zeppelin song that was lost by the BBC for over 40 years (Far Out)

During Led Zeppelin’s 12 years together, the group released eight studio albums, each composed of tracks Jimmy Page and company believed to be the best representation of the group at that specific moment in time. When amassed, these albums trace the evolution of Zeppelin’s style, approach to production, individual musical skills, and songwriting habits. And while we might have assumed this rendering of Zeppelin’s musical life to be complete, it would seem that we’ve not been given the full picture. Indeed, there are certain Led Zeppelin songs that even some of the group’s most die-hard fans never knew existed.

Following the release of the Led Zeppelin compilation album BBC Sessions in 1997, Jimmy Page began hearing a bootleg version of a song he hadn’t heard in just under 30 years. The band had never attempted it during an album session, and it never appeared on any of their records. After a bit of digging, Page realised that the track had come from a BBC performance Led Zeppelin made in the first months of 1969. Unfortuantely, it transpired that the BBC had managed to lose the tape from that day, meaning that Page was forced to track down a copy of the song a fan had recorded off the radio back in ’69.

How One Music Station Covered The Buffalo Massacre (Radio Ink)

(By Tom Langmeyer) The unfortunate conventional wisdom that has prevailed in radio during the last 20 years is “We are a music station. We don’t do news.” Unfortunately, this sentiment represents many people who set the tone for the industry and make these proclamations proudly, as the radio business becomes more and more irrelevant.

There is some truth to the statement that a “music station should not be covering news” by those who think completely linearly. However that culturally process-driven approach that has zero to do with results.

A music-intensive radio station is not expected to do news in the traditional sense, nor should be competing with news stations. It’s not a music station’s role.

However, all radio stations must have a component of “news. Now, before folding your arms across your chest, think about it this way.

“News” is really what your listeners need and want in the radio experience. What does “news” mean for your station? What is it? How is it delivered? How much? How do we activate our listener? That’s where things are different and need to be defined.

Think about a great country station that’s talking about a concert that’s happening in town and building an experience around it. That’s NEWS.

No one is saying a music station should be WINS, WBBM, KNX or KCBS.

No matter the music format is, there needs to be a playbook for how and what information (relevant “news”) gets presented.

On the advising side of Great Lakes Media’s business, we create customized plans for stations committed to localism and winning on the revenue hill. Sure it’s different – and that’s why it works.

It’s called the “Great Lakes Media Way.” [Continue reading at Radio Ink…]

FCC Sends Pirate Radio Notices to Property Owners (Radio World)

Agents traced signals in Pennsylvania, Maryland and Oregon

The Federal Communications Commission has sent notices to several property owners of alleged pirate radio activities on their properties.

The letters from the Enforcement Bureau are headlined “Notice of Illegal Pirate Radio Broadcasting.” They remind the owners that federal law now provides for fines of up to $2 million “if we determine that you have continued to permit any individual or entity to engage in pirate radio broadcasting from the property that you own or manage.”

The bureau said its agents used direction finding techniques to source these FM signals. It mailed letters to Richard Manson for broadcasts on 103.5 MHz in Philadelphia in January; to Maria V. Hernandez of Kissimmee, Fla., for signals on 87.9 MHz in Hazleton, Pa., in January; to Edwin and Joyce Pitt of Baltimore, Md., for signals on 91.3 in February; and to Kent and Deanna Coppinger for signals on 100.5 MHz in La Grande, Ore., in March.

Hamvention to kick off this weekend in Xenia; Thousands expected to attend (Southgate ARC)

After nearly three years, Hamvention is back.

The convention is the world’s largest amateur radio gathering at Greene County Expo Center, according to the event’s website.

Around 30,000 visitors are expected to come to the event from all over the world.

Michael Kalter, the spokesperson for Hamvention, said that based on numbers from the Greene County Convention Visitors Bureau, Hamvention adds $30 million to the local economy.

He said amateur radio, also known as ham radio, is something people of all ages and backgrounds can be a part of, which is why he thinks the convention draws such a large crowd.

Kalter shared how it feels to bring so many people from around the world together. “That makes me feel really good,” Kalter told News Center 7?s Kayla McDermott. “I’m glad that the hobby seems to be really growing and flourishing,” he added.

There are no COVID-19 restrictions in place for this year’s convention. With thousands of people expected to attend, safety is a top priority. Before entering the convention center, people must have their bags checked. The Greene County Sheriff’s Department said they have prepared for the event.

Major Shawn Prall, with the sheriff’s office, said they have a plan in place to make sure traffic moves along smoothly as there are only two lanes to get to the grounds. Crews will also keep an eye on the weather, in case there is a chance for it to turn severe. Prall said this will be his fourth Hamvention and he has never had an incident. “We’re taking precautions, both that the public will see in uniform presence and also things that they can’t see. Just trying to keep everybody safe and be ready for any kind of incident, whether it be weather or manmade or anything like that,” Prall said.

The convention runs this weekend 9 a.m.-6 p.m. Friday, 9 a.m.- 5 p.m. Saturday and 9 a.m.-1 p.m. Saturday.

Sherwood Tools Available (K4FMH Blog)

The work that Rob Sherwood NC0B has contributed to the public over the past decade is unique and an amazing service to hams worldwide. I’m talking about, of course, his summary Table of receive bench tests published at this Sherwood Engineering website. He is independent so no one can think that advertising dollars could skew his assessments or how he presents them. As a CW contest operator, he is very clear that he sorts his table on the basis of what his experience and training has shown him to be the single most important measurement in his table: the narrow dynamic range.

I am not a CW operator or accomplished contester (lol) but enjoy the latter with my small team of fellow hams. But I am a statistician who likes to focus on problems where analytic tools can help foster a wider understanding of the data surrounding the problem area. So, working with Rob NC0B, I’ve created a set of “Sherwood Tools” to visualize his data as well as link them to a couple of other critical aspects of a rig purchase: market-entry price, consumer satisfaction, and the year the radio entered the market. These four vectors of data drive all of these tools, now available over at foxmikehotel.com.

The tools include a sortable Sherwood list where you can sort on any of the nine tests he publishes as well as the composite index of them that I created and included in my two-part NCJ articles in 2021. A set of 3D data visualizations are available to simultaneously view radios on four data elements (that does make it 4D, technically). Several graphs illustrate key aspects of the data, including how to not get tripped-up in the “ranking” of radios where the bench measurements are just not appreciably different. Seeing how the past 50 years of radios appearing in Rob’s Table have made a remarkable and clear progression toward the best receiver performance that modern test equipment can detect is in another tool. In addition, how the trend in getting a receive bang-for-the-buck has progressed over this 50 year period is there, too. Finally, I’ve used the industry-standard tool by Gartner, the Magic Quadrant, to help isolate radios in Rob’s Table that perform and are rated above average at various price points. I call these the Golden Quadrant Lists. Continue reading →
