RNZ welcomes Pacific infrastructure investment

Released at 3:19 pm on 19 May 2022

RNZ Chief Executive and Editor-in-Chief Paul Thompson has welcomed the budget investment in RNZ Pacific shortwave transmitters.

In Budget 2022 the Government announced $4.4 million dollars capital funding for a new transmitter for RNZ Pacific.

RNZ Pacific broadcasts into the wider Pacific on shortwave 24 hours a day, collaborating with 22 broadcasting partners across the region. Its current primary transmitter is nearing end of life, and its other transmitter has in effect already been retired.

“The value of the RNZ Pacific service can’t be underestimated. Our voice reaches all parts of the Pacific, at times with critical information such as cyclone warnings. During the Tonga eruption, when the undersea cable was cut, RNZ Pacific short wave was a lifeline source of information,” said Thompson.

This investment secures a productive future for our unique voice. The attraction of the shortwave service is its robustness, and the ability to have the signal travel great distances, and achieve good audiences,” he said.

RNZ Pacific broadcasts enhance the Government’s Pacific strategy as we share our history, culture, politics and demographics. The strategy is underpinned by the building of deeper, more mature partnerships with Pacific Island countries, and by supporting their independence and sustainable social and economic resilience.

Since the ABC ceased its shortwave broadcasting the only other shortwave broadcaster in the region is Radio China. Thompson says RNZ can now start work on its infrastructure development with a new transmitter likely to take approximately 12 months to get in place depending subject to further project planning.

Public Service Media Continue To Mobilize Wide Range Of Support For Ukrainian Refugees (EBU)

More than 14 million people have fled their homes since Russia’s invasion of Ukraine and the war shows no sign of ending. For World Refugee Day on 20 June, we are highlighting some of the issues faced by displaced Ukrainian people – and reaffirming that the support from the EBU and its Members will continue.

That support has manifested across a range of projects:

Air strikes on the TV towers in Kyiv and Rivne underlined the vulnerability of broadcast communications in a war zone. Together with our Members, we have coordinated the supply and delivery of critical equipment such as IP connectivity solutions, satellite phones, AM transmitters, and studio support to enable the uninterrupted transmission of vital news and information.

In these circumstances, being able to rely on accurate news sources is key. Many EBU Members have launched dedicated news services specifically for refugees in their own language, so that they can tap into vital updates from home, wherever in the world they are. Rai News in Italy has a daily news bulletin in Ukrainian; RTBF UKRAINE is a new web-based radio station for Ukrainian refugees in Belgium, with 100% of its content in Ukrainian; and Yle in Finland has a Ukrainian-language news service for providing the latest news bulletins in Ukrainian. Many public media outlets are also re-transmitting content directly from Ukrainian public broadcaster, UA/PBC for Ukrainian refugees.

Providing practical information to help people navigate the uncertainties of settling into new homes has also been a priority and has seen the launch of many dedicated programming and channels: GPB has a hotline for Ukrainians in Georgia; Czech Radio and Radio Prague have launched a podcast, ‘News for Ukrainians in Czech Republic’, that offers practical information for incomers. While ARD in Germany presents How To Deutschland Insta; Swedish Radio’s Ukrainian service for new arrivals includes practical advice on how to access medical care or education facilities for kids and RTP’s online service helps with learning a new language.

For children, displacement through war is particularly traumatic. TVP in Poland has developed a site for kids from Ukraine which, as well as showing selected content in Ukrainian, also presents lessons in learning Polish; ARD and ZDF in Germany have included content in Ukrainian for children, including German-language learning programmes, and Czech Radio has recorded fairytales in Ukrainian.

Noel Curran, Director General, EBU, said “Few of us can understand the trauma of being forced to leave our homes, not knowing when or if we will return. I’m proud to belong to a community that has mobilized a wide range of practical support so quickly while ensuring trusted news and information continues to reach those who need it, wherever in the world they are. World Refugee Day is a moment to reflect on a situation that continues to need targeted support. And to reaffirm our commitment to giving it for as long as it takes.”

Rising Energy Costs Could Spur Digital Migration (Radio World)

Projected cost reductions cited as reason for Germany to accelerate the migration to DAB+

As energy costs rise, Deutschlandradio Director Sefan Raue sees a further reason to hasten an FM switch-off for Germany.

“We will not be able to afford two terrestrial distribution channels in the long run. The signs are clearer than two or three years ago,” Raue told German press agency dpa, according to Hadelsblatt. “FM is an energy guzzler.”

A public broadcaster, Deutschlandradio is based in Cologne and Berlin and operates several national channels on DAB+ and FM. The channel been steadily replacing its remaining FM transmitters with DAB+; six of its short-range analog transmitters are going dark at the end of June 2022. The broadcaster expects to have at total of 161 locations broadcasting its DAB+ channels nationwide by year-end, reaching some 90% of the German populace. [Continue reading at Radio World…]

Radio Waves: Solar Cycle 25 Looking Up, Vintage Radio Flea Market Finds, the SBITX SDR, and More Power to Radio Caroline

Radio Waves: Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers. To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Revised prediction for Solarcycle 25 (Southgate ARC)

A revised prediction from the NASA High Altitude Observatory based at the University Of Colorado.

NASA Heliophysicists have released a revised prediction for Solar Cycle 25.
The report generated by Ricky Egeland a Solar Physicist working in the NASA Space Radiation Analysis Group now calls for the peak of Solar Cycle 25 to top out at a value of 195 ± 17 based upon the new scale for calculating Smoothed Sun Spot Number. For reference Solar Cycle 21 peaked at an SSN 233 (new scale) while Solarcycle 23 peaked at an SSN of 180 (new scale). If this predictions holds up Ham Radio will see Excellent Worldwide F Layer Conditions on 10 Meters for several years around Solar Max. 6 Meters conditions should be good in the Equinox Periods before and after Solar Max with consistent openings on Medium Haul Polar Routes. 6 Meter routes traversing the equator should experience consistent openings ± 9 months from Solar Max.

Ricky Egeland is a particpating member in the group headed up by Scott McIntosh and Bob Leamon that published a paper 9 months ago outlining the existance magnetic bands within the Sun that govern the Sunspot and Hale Cycles. At the time of its publishing the paper went on to predict the peak of Solar Cycle 25 could be as high Solarcycle 21. Today’s released is a revised prediction based upon data observed since the original paper was published. To be sure we are still in early days.

The Solar Rotation Cycle as marked by Sunspot Activity was established on April 19, 2021 so we are only 90 Days into actually observing Cycle 25 Activity. It is now agreed the dramactic run-up in Sunspot Activity we experienced late Last Fall while tied to Cycle 25 was an outlier. When asked directly about whether they can declare if the Terminator Event they wrote about in the Fall 2020 Paper has occurred Scott McIntosh stated “We can’t be sure just yet but we are very very close”. It also should be noted that while it has been over a year since the sun produced a Cycle 24 Region with a Sunspot worthy of a NASA Classification the Sun has been steadily producing Spotless SC 24 Active Regions the last of which formed right on the Solar Equator at N00-W54 on July 24,2021 as recorded by Jan Alvestad’s Solar Terrestial Activity Report Website. These Active Regions being part of a Solarcycle in its final stages of existence produce no spots and only last for a few hours before they dissipate away. The previous SC24 Active Region formed on June 28, 2021. Once the SC24 active regions cease forming Solar Cycle 25 will take off in earnest.

Flea Market Finds at the Vintage Radio & Communications Museum of Connecticut (KE1RI)

I have an addiction to old radios, especially anything that was manufactured in the 1923-1950 period. That may seem like a long time to some folks but when you gain senior citizen status 25 years is a blink of the eye. This love of old radios is tempered by the limited display space that I have in my home. I am at the point where I am very selective when it comes to buying a new radio. Although there is always room for another ‘small’ radio I am somehow attracted to the larger models. A rough count of the full-size consoles in this house (and garage and shed) comes to about 11. Just in this room (second floor radio shack) there are 5 console radios, two of which reside in the closet. The only surprise is that my wife has not tossed the radios and me out by now.

So, it is no surprise that I enjoy attending radio flea markets. Most of the events I frequent are either in Connecticut or Massachusetts. Rhode Island has very little in the way of antique radio flea markets (although we do have a great wireless and steam museum). And you can forget about eBay. Radios on eBay usually have inflated prices and descriptions. Even if you do find something reasonable the shipping for anything bigger than an All American Five table model is very costly and hazardous (many are damaged during shipping).

This is where the Vintage Radio & Communications Museum of Connecticut (VRCMC) comes in. This is a wonderful museum that has an enormous collection of radios and other communication-related technological wonders. They also hold regular flea markets to help raise funds needed to run the museum. During the cold months the events are inside (limited space) and during warm seasons (April, June, September) they are outside (plenty of space). This year I attended the first Spring event that was held on April 13, 2021. It was a great success! [Click here to continue reading…]

SBITX: Hackable HF SDR for the Raspberry Pi (Hackaday)

Cheap, easy to use SDR dongles are an immensely powerful tool for learning about radio technology. However, building your own SDR is not something too many hackers are confident to tackle. [Ashhar Farhan, VU2ESE] hopes to change this with the sBITX, a hackable HF SDR transceiver designed around the Raspberry Pi.

[Ashhar] introduced the project in talk at the virtual “Four Days In May” annual conference of the QRP Amateur Radio Club International. Watch the full talk in the video after the break. He first goes over the available open source SDR radios, and then delves into his design decisions for the sBITX. One of the primary goals of the project was to lower the barrier of entry. To do this, he chose the Raspberry Pi as base, and wrote C code that that anyone who has done a bit of Arduino programming should be able to understand and modify. The hardware is designed to be as simple as possible. On the receive side, a simple superheterodyne architecture is used to feed a 25 kHz wide slice of RF spectrum to an audio codec, which send the digitized audio to the Raspberry Pi. The signal is then demodulated in software using FFT. For transmit, the signal is generated in software, and then upconverted to the desired RF frequency. [Ashhar] also created a GUI for the 7? Raspberry Pi screen.[…]

Ofcom agrees for Radio Caroline to turn up the power (Community Radio Today)

A power increase has been agreed for Radio Caroline to extend its coverage area from Suffolk and Essex to include Kent as East Sussex.

The station is broadcasting under a community radio licence and was originally granted 1kW of power on 648 AM in 2018. The actual power increase amount has not been announced.

Ofcom says a power increase was agreed to combat man made noise and interference in the existing coverage area, and to extend coverage to adjoining areas.

While the subsequent increase in the licensed area was considered to be significant, the decision-maker deemed there to be exceptional circumstances in order to approve this request, saying the service has experienced high levels of background noise and interference, particularly in urban areas.

The licensee also serves a ‘community of interest’ as opposed to a defined geographic community meaning the service is positioned to be accessible to the community of interest in the proposed extended areas.[…]

Radio Waves: Stories Making Waves in the World of Radio

Many thanks to SWLing Post contributors Mike Terry, Dave Zantow, and John Figliozzi for the following tips:

WLW-AM Begins 100th Year On Air (WVXU)

It wasn’t Cincinnati’s first radio station, but WLW-AM is still the biggest.

Cincinnati industrialist Powel Crosley, Jr. began broadcasting WLW-AM over a 20-watt station from his College Hill home on March 2, 1922 – which means that the station is entering its 100th year today.

WLW-AM wasn’t Cincinnati’s first commercial radio station, but it is the oldest surviving station from the 1920s. WMH was operated by the Precision Instrument Co. from Dec. 30, 1921, to January 1923. WMH was sold to Crosley and merged into WLW, says Randy Michaels, the former WLW-AM programmer and Jacor/Clear Channel executive who is the best radio historian I know.

In 1934, WLW-AM became “the Nation’s station” when President Franklin D. Roosevelt flipped a switch in the White House to activate the station’s unprecedented 500,000-watt experimental transmitter under its Tylersville Road tower. WLW-AM broadcast at “super power” around the clock for five years, through 1939, and continued the mega-wattage output midnight-2 a.m. until 1943. For years WLW-AM has boasted that the 50,000-watt signal reaches 38 states. (I’ve heard the station in New Jersey, Maryland, North Carolina, Florida, Georgia, Illinois and Missouri.)

For 99 years, WLW-AM has broadcast some of the most popular personalities in town: Jim Scott, Gary Burbank, Bob Trumpy, Marty Brennaman and Joe Nuxhall, Cris Collinsworth, Jim LaBarbara, Bill Cunningham, Mike McConnell and Dale Sommers. Before them came Ruth Lyons, Bob Braun, Doris Day, Rosemary Clooney, newsman Peter Grant, sportscaster Red Barber and comedian Red Skelton.

Although WLW-AM likes to promote itself as “news radio,” it’s perhaps best known for carrying Reds and most Bengals games, plus University of Cincinnati football and basketball and Xavier basketball.[…]

WWVB broadcast system upgrades may include temporary outages (WWV)

The WWVB broadcast system is being upgraded with new equipment to improve the reliability of the signal. In order to install this equipment, beginning on March 9, 2021 the WWVB signal may be operated on a single antenna at approximately 30 kW radiated power for periods up to several days in duration, and may have occasional outages. Periods of reduced power operation lasting longer than 30 minutes will be logged on the WWVB Antenna Configuration and Power web page, and any outage longer than five minutes’ duration will be recorded on the WWVB Outage web page. Upgrades are expected to be complete by March 31, 2021.

Ofcom released age of radio amateurs data (Southgate ARC)

Following a Freedom of Information request about the age of radio amateurs Ofcom said they do not hold Date-of-Birth information for many radio amateurs but released what information they do have

Ofcom say “We do not hold a full breakdown of the age of issued amateur radio licensees as date of birth is not a mandatory field for licence applications.”

In September 2000 the then communications regulator (RA) abolished the ban on people under 14-years-old holding a Full amateur licence, since that time a person’s date of birth has served little regulatory purpose.

The data Ofcom released showed they only had Date-of-Birth information for:
7,312 out of 28,845 Foundation licences
4,104 out of 12,127 Intermediate licences
44,944 out of 54,072 Full licences

As of March 1, 2021 there was a total of 95,044 valid UK amateur radio licences.

Unlocking the Airwaves (UMD)

Unlocking the Airwaves: Revitalizing an Early Public and Educational Radio Collection is a comprehensive online collection of early educational public radio content from the National Association of Educational Broadcasters (NAEB). The forerunner of CPB and its arms, NPR and PBS, the NAEB developed and distributed educational radio programs and accompanying print materials to schools and communities across the United States. What’s more, the NAEB lobbied extensively to unlock the airwaves—to access precious frequency space—in order to bring the voices of poet Robert Frost, architect Frank Lloyd Wright, anthropologist Margaret Mead, and conservationist “Ranger Mac,” among many other individuals, into American homes and classrooms.

The NAEB’s history is the dramatic story of idealists who believed in the utopian possibilities of technology for education and social uplift and who faced considerable challenges in pursuit of those goals, including economic depression, world war, and the scarcity of the electromagnetic spectrum. It’s a story that has much to tell us about 20th century American culture, as well as the 21st century’s environment of online educational technology and podcasting that we live in today.

Despite its historic importance and contemporary relevance, most of the NAEB members’ programs were never heard again after their initial brief moments on the air. The archives for the radio programs and their related paper documentation have been split for over 25 years between two institutions: the University of Maryland and the Wisconsin Historical Society. Unlocking the Airwaves reunites the split collections, finally realizing the potential of the collections of the NAEB for exploration and and the broader public.

Radio Waves: Hacking Satellites, “Close-Knit” Ham Radio Culture, TV Drama Diplomacy, and Ofcom Relaxes Restricted Service Licence

Radio Waves: Stories Making Waves in the World of Radio

Many thanks to SWLing Post contributors BJ Leiderman, London Shortwave, and Michael Bird for the following tips:

Hacker Used £270 of TV Equipment to Eavesdrop on Sensitive Satellite Communications (CBRonline.com)

“Vulnerable systems administration pages and FTP servers were publicly routable from the open internet.

An Oxford University-based security researcher says he used £270 ($300) of home television equipment to capture terabytes of real-world satellite traffic — including sensitive data from “some of the world’s largest organisations.”

James Pavur, a Rhodes Scholar and DPhil student at Oxford, will detail the attack in a session at the Black Hat security conference in early August.

Pavur will also demonstrate that, “under the right conditions” attackers can hijack active sessions via satellite link, a session overview reveals.

The news comes as the number of satellites in orbit is expected to increase from approximately 2,000 today to more than 15,000 by 2030. (Elon Musk’s SpaceX alone has permission to launch 12,000 satellites.)[…]

A close-knit culture, with separation at its core (Christian Science Monitor)

Ham radio operators are a global collective with a common aim: to forge human connections in an expanding network. As COVID-19 makes us all ‘distance,’ we wanted to tune in to their world.

https://youtu.be/BMeVY_JyLFk

You’re logged in, the Zoom meeting underway, and suddenly faces freeze. The best you can do: Reboot the router and cross your fingers. You’re on the phone with a friend, deep in conversation, and the audio gets garbled as the bars on your phone drop from one to none. Technology can fail us at inconvenient times. But imagine a communications technology that could hold up even in the most rugged and remote situations.

It exists, and it’s much older than the smartphone.

Amateur radio, or ham radio, has been around for more than a century, functioning as both workhorse and recreational hobby. After the Boston Marathon bombing in 2013, amateur operators coordinated communications as cellphone systems became overloaded. They played a key role in Puerto Rico in 2017 after Hurricane Maria took down much of the communications infrastructure. Though there hasn’t been as much of a need during the pandemic – with traditional systems up and running – amateur radio is keeping its own user communities in touch, informed, and emotionally grounded.[…]

Australia criticised for TV drama diplomacy (Radio New Zealand)

[Listen to full interview above or at RNZ.]

Australia has been told it should not send low-brow TV dramas and reality shows to the Pacific, but find out what the region really wants.

Canberra has announced plans to stream television content to the Pacific as part of efforts to promote Australia’s relationship with the region, and to counter Chinese influence.

But a spokesperson for advocacy group, Australia Asia Pacific Media Initiative, Sue Ahearn, says sending programmes like Neighbours, Border Force is not the answer.

She believes Australia could provide a much greater service for the Pacific.[…]

Update: Licensing drive-in movies and church services (Southgate ARC)

Drive-in movie and church service event organisers could be granted temporary radio licences by Ofcom, which may allow film lovers and congregations to come together while still observing social distancing.

Ofcom has today updated its licensing information to offer guidance to individuals or organisations who may wish to hold these types of events. They require a ‘restricted service licence’ from Ofcom, so that people in their cars can hear the film soundtrack, or what is being said, on their FM car radios.

Given the current coronavirus pandemic, we are waiving the usual 60-day notice period for licence applications. We will also process applications quickly, with the aim of providing an answer to applicants within two weeks of it being received.

We recognise that these events may be a way for communities and congregations to enjoy a film or to worship, while still observing social distancing. In granting any licence, however, we are not authorising the event itself. It is for licensees to ensure that any events are permissible under Covid-19-related laws and guidance.

More information, including on how to apply for a restricted service licence, is available.

Small-scale DAB could lead to hundreds of new UK radio stations

2 Replies

(Source: Southgate ARC)

Hundreds of new local digital radio stations could start broadcasting in the UK from next year, under proposals outlined by Ofcom

Ofcom say:

With over 40% of the UK’s radio listening now taking place on the Digital Audio Broadcasting (DAB) platform, today’s proposals mark a major step towards expanding local DAB coverage, giving listeners an even wider choice of new digital radio stations.

Small-scale DAB is cutting-edge technology, pioneered in the UK by an Ofcom engineer. It provides local commercial, community and specialist music stations with a low-cost route to hitting the digital airwaves.

The consultation sets out:

• our proposed spectrum and licensing process;
• our approach to developing a coverage area plan; and
• how we intend to advertise licences and assess applications.

We would like to hear from interested parties by Friday 4 October and intend to start advertising licences early in 2020.

The Internet and community licenses have changed the London pirate radio scene

2 Replies

Many thanks to SWLing Post contributor, David Korchin (K2WNW), for sharing the following article from The New York Times:

London’s Radio Pirates Changed Music. Then Came the Internet.

LONDON — In 1993, the illegal radio broadcasters at Kool FM came up with a plan to keep the regulators from raiding their studios.

In those days, the rooftops of South and East London still bristled with unauthorized antennas. Installed by pirate radio stations on top of public housing blocks — the city’s tallest and least secure buildings — they transmitted sounds rarely heard on the BBC or commercial stations. Kool FM was at the heart of the scene, broadcasting jungle, rave, and drum and bass music from the Hackney district of East London.

All the pirates needed was a key to the building — easy to buy off a building worker or tenant — and a cheap transmitter. But they had a problem. Illegal broadcasting is, well, illegal, and, in Britain, pirates can face up to two years in prison, unlimited fines, bans from appearing on legal stations and equipment seizures.

So the pirates at Kool FM covered their studio door with concrete. To get in, they had to scale the outside of the building, jumping from balcony to balcony, said one of the station’s founders, who declined to give his real name but who broadcasts as Eastman. On a recent afternoon, he was standing outside Kool’s current studio in a warehouse on London’s outskirts. Drum and bass sounds from a D.J. called Papa G. emanated from behind the wall.

The regulators rarely bother them now, he said, and capers like the one he described are scarce. In the early 1990s, Kool “was the in thing,” said Eastman. But he estimated that Kool has lost 90 percent of its advertising revenue since its heyday. “We’re struggling because it’s hard to raise money to keep the station going.” Kool has recently rebranded as Kool London, and started focusing more on broadcasting online, though its shows still go out on the old pirate FM frequency.

Kool’s problems are part of a broader trend: Ofcom, the British communications regulator, estimated there are now just 50 pirate stations in London, down from about 100 a decade ago, and hundreds in the 1990s, when stations were constantly starting up and shutting down. Ofcom considers this good news, because illegal broadcasters could interfere with radio frequencies used by emergency services and air traffic control, a spokesman said.[…]

[T]wo things happened that changed the landscape of underground radio: first, the internet, and second, new licenses that encouraged pirates to reinvent themselves along more official lines.[…]
