As Disasters Roil Earth, A New Sun Cycle Promises Calmer Weather — In Space (NPR)

Giant flares and eruptions from the sun can cause space weather, and stormy space weather can interfere with everything from satellites to the electrical grid to airplane communications. Now, though, there’s good news for people who monitor the phenomenon — the sun has passed from one of its 11-year activity cycles into another, and scientists predict that the new cycle should be just about as calm as the last.

That doesn’t mean, however, zero risk of extreme weather events. Even during the last, relatively weak solar cycle, drama on the sun triggered occasional weirdness on Earth like radio blackouts, disruptions in air traffic control, power outages — and even beautiful aurorae seen as far south as Alabama.

Over each solar cycle, the roiling sun moves from a relatively quiet period through a much more active one. Researchers monitor all this activity by keeping an eye on the number of sunspots, temporary dark patches on the sun’s surface. These spots are associated with solar activity like giant explosions that send light, energy, and solar material into space.

Counting of sunspots goes back centuries, and the list of numbered solar cycles tracked by scientists starts with one that began in 1755 and ended in 1766. On average, cycles last about 11 years.

Based on recent sunspot data, researchers can now say that so-called “Solar Cycle 24” came to an end in December of 2019. Solar Cycle 25 has officially begun, with the number of sun spots slowly but steadily increasing.[]

WWJ in Detroit: A 2020 Centennial Station (Radio World)

Iconic AM station just celebrated the 100th anniversary of its first broadcast

It was shortly after World War I that Clarence Thompson, a partner of Lee de Forest, formed a new company Radio News & Music Inc. in New York. His goal was to encourage newspapers to broadcast their news reports by wireless, using de Forest transmitters.

The franchise offer — available to only one newspaper in each city — offered the rental of a de Forest 50-watt transmitter and accessories for $750. Just one newspaper signed up for the deal; it was the Detroit News, led by publisher William E. Scripps.

He had been interested in wireless since investing in Detroit experimenter Thomas E. Clark’s wireless company in 1904. Scripp’s son, William J. “Little Bill,” was an active ham radio operator, operating a station in the Scripps home.

People Might Laugh

Scripp proposed accepting the Radio News & Music offer and building a Detroit News radio station in 1919, but he met resistance from his board of directors. It was not until March of 1920 that he was given the go-ahead to sign a contract.

The de Forest transmitter was shipped to Detroit on May 28, 1920, but was lost in transit; a second transmitter was constructed and sent on July 15. This delayed the installation of the station until August.[]

Czech Radio has expanded DAB + coverage to 95 percent of the population and announced the switch-off of medium waves (Digitalni Radio)

NOTE: This is a machine translation of the original post in Czech.

Czech Radio has entered another, important phase of radio digitization. To date, the ?Ro DAB + multiplex signal has reached 95% population coverage. Ten new transmitters were launched in Bohemia and Moravia. You can find a detailed description of them below.

DAB + technology is becoming a common distribution channel for Czech Radio, which will be placed on the same level as analogue FM / FM broadcasting. All marketing activities will already include the “DAB + More Radio” logo. ?eské Radiokomunikace is planning to start certification of receivers next year in order to protect customers and facilitate orientation in the range for them and retailers.

According to the CEO of Czech Radio, René Zavoral, the public service media is proceeding in accordance with a long-term strategic plan. The head of communication and press spokesman Ji?í Hošna describes the step as a turning point that can affect the direction of the entire radio market.[]

UK amateur radio exam report released (Southgate ARC)

The RSGB Examinations Standards Committee (ESC) report covering 2019 is now available for anyone to download

The report contains statistics for the both the RSGB amateur radio exams and the Air Cadets Organisation (ACO) exam which Ofcom considers to be equivalent to the RSGB Foundation.

Ofcom has been concerned about the participation of women in amateur radio and STEM disciplines. They requested the ESC to publish figures for the number of women taking the exams. Unfortunately the results are disappointing with only 9.9% of all exams being taken by women.

SABA partners with T&A and Sentech to deliver digital radio in SADC (Advanced Television)

The Southern African community will soon enjoy digital audio broadcasts, thanks to an initiative lead by a South African based entity, Thembeka & Associates that has taken the lead in implementing the much anticipated interactive radio solution.

This was announced by the Secretary-General of the Southern African Broadcasting Association, SABA, Mr Cecil Jarurakouje Nguvauva, following the conclusion of initial agreements between the participating entities. Welcoming the digital radio solution to the SADC region, Nguvauva emphasised the need for rural communities to be engaged fully in the developmental agenda of the respective African governments if the planned development is to add value to the lives of the most disadvantaged members of our society.

Chief Executive Officer of Thembeka & Associates, Madam Thembeka Kaka has hailed this initiative a huge success for the continent and a dream come true for her institution. Madam Kaka added that as a member of the National Committee on ICT Chamber Accessible Broadcasting for People Living with Disabilities, she has passionately driven this project for a long while. Madam Kaka added that “Following the announcement of the Policy Directive that has introduced Digital Sound Broadcasting by the South African Minister of Communications & Digital Technologies, Stella Ndabeni-Abrahams in July this year. I have since realised that greater opportunities have emerged for the broadcast industry as a whole. And this initialises an evolution of radio broadcasts going forward,” she stated.

Sentech’s Meyerton Radio Shortwave site in South Africa will carry the Digital Sound Broadcasting Shortwave Transmission from the broadcast centre in Southern Africa to the rest of SADC countries.

For the initial stage, only six countries are earmarked for the coverage, before it is rolled out to the rest of the SADC Region. The targeted countries are Namibia, Botswana, Lesotho, Eswatini, Zambia and South Africa. The rapid deployment is planned to work alongside the existing analogue radio service, which will seamlessly transition to a fully-fledged Digital Radio transmission in SADC. The receivers to be deployed will have the capabilities to receive and transmit both Analogue and Digital radio signal on FM and AM.

The primary purpose of the initiative is for governments and various newsmakers to urgently provide vital information to all citizens, especially the rural, remote and marginalised vulnerable communities. The outbreak of COVID-19 has amplified the need for this undertaking, that has highlighted risk areas in our various communities. Particular emphasis will be given to the following sectors in the respective communities: Education Sector; Health Sector; Socio-Economic factors; Gender issues; Youth & Disability.[]

Listening Out, Listening For, Listening In: Cold War Radio Broadcasting and the Late Soviet Audience (Wiley Online Library)

Abstract

This article interrogates the well?known phenomenon of western broadcasting to the Soviet Union from the little?known vantage point of the audience’s sonic experience and expression. I use the example of the BBC’s main popular music program in the late USSR, Rok posevy, with its remarkable presenter, Seva Novgorodsev, to explore fundamental questions about the who, how, and why of listening to the so?called “enemy voices.” The popularity of Novgorodsev’s show, I argue, is best understood in the context of the Soviet soundscape and, in particular, of longstanding Soviet media practices, including radio jamming and Soviet ideologies of the voice. Novgorodsev’s Rok posevy presented listeners with a powerful alternative sociocultural space, one that promoted models of authority and community very different from Soviet norms and, indeed, antithetical to Soviet norms.[]

Swedish Electrical Safety Agency threatens ban on sale of optimizers (Southgate ARC)

In Sweden the Swedish Electrical Safety Agency may ban the sale of optimizers used in Solar Panel installations due to the high level of RF Pollution they produce

A translation of an SSA post reads:

The Swedish Electrical Safety Agency wants to remove optimizers that spread interference. “It should be easy for the electrician to do the right thing.”

– We want to remove all solar cell products that spread disruption from the market. It should be easy for the electrician to do the right thing, and if you choose CE-marked gadgets and follow the manufacturer’s instructions, the system should be nice, says Martin Gustafsson, who is an inspector in market control at the Swedish Electrical Safety Agency. reports of disturbing solar cells. In addition to radio amateurs such as Anders Ljunggren, the  mobile operator Telia is among those affected . The Swedish Electrical Safety Board has made inspection visits to disturbing facilities, and carried out a market review of optimizers and inverters from eleven different manufacturers.

“They take advantage of a gap in the standard and instead hide behind a general EMC standard.”

The report is not complete yet. However, one of the conclusions is that a number of manufacturers of interfering products have chosen not to use the standard developed for photovoltaic products, but which has not yet been harmonized by the European Commission.

– They use a gap in the standard and instead hide behind a general EMC standard, which does not make any demands on the dc side. This makes our evidentiary situation difficult. But if the disruption problems are not solved, the products can be banned from sale, says Martin Gustafsson.

New Ham Radio Onboard The ISS Is On The Air (K0LWC Blog)

Ham Radio operators have enjoyed making contact with the ISS for many years. The holy grail has always been talking to ISS astronauts on FM simplex (145.800) — but those can be rare chance encounters. Ham radio operators have also enjoyed slow-scan television (SSTV) broadcasts and APRS packet radio via the ISS digipeater. Now we get to work the world’s most expensive FM repeater thanks to the new InterOperable Radio System (IORS) installed on the ISS.

The InterOperable Radio System (IORS) replaces an ancient Ericsson radio system and packet module that were certified for spaceflight over two decades ago. The 5 watt HT that was aboard the ISS was getting worn out after many years of use. The Ericsson radio looks like something from a 1990s episode of Cops.

The new IORS was launched from Kennedy Space Center on March 6, 2020 onboard the SpaceX CRS-20 resupply mission. It consists of a custom space-modified Kenwood D710GA transceiver and an ARISS-developed multi-voltage power supply. The equipment was installed by NASA astronaut Chris Cassidy (KF5KDR).

New Kenwood D710G ‘Space Flight Edition’

The radio now being used is a Kenwood D710G and was engineered specifically for space flight. JVCKENWOOD USA and the ARISS worked closely to modify the D710G. The upgrades were performed by JVCKENWOOD and include:

  • Output power is hardware limited to 25 watts for the safety of the International Space Station
  • Custom firmware and menus tailored for operation onboard the ISS.
  • Higher output/high-reliability fan to allow continuous repeater operation.

Continuous fan operation is an important feature in space for the reliability of the radio. There is no convection in microgravity, so all heat-generating components need to be cooled by moving air or conduction. If the radio burns up, there isn’t a Ham Radio Outlet down the street to grab parts.[Continue reading the the full article at K0LWC’s blog…]

ZOE: More Tristan Da Cuhna QSL cards in the wild–?

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following guest post:


SWLing Post readers may recall the story we published last year about the appearance of a rare QSL card from Tristan da Cunha. ZOE Tristan was for decades one of the most sought after stations — it used 3,290 kHz and had a power of 40 watts.

Recently, I received correspondence from a former editor of the old SPEEDX club bulletin who provided copies of two pages from the bulletin from decades ago. These pages make clear that the QSL I obtained in an Ebay auction was not the card that Dave Sharp received:

Dave was, at one point, editor of the DX Montage section of SPEEDX. As can be seen, the ZOE card that he received was signed by a A.L. Patterson while the one I obtained through auction contained a different signer consistent with a QSL received by South African DX’er Eddie de Lange in 1973. However, the card I received was NOT the one pictured in a story about Tristan published in 2010 — the postmark date is different.

That story noted that three DX’ers from South Africa “did manage to receive and QSL ZOE Radio Tristan – Ray Cader, Gerry Wood and Eddie de Lange were among a handful of fortunate Radio Tristan QSL recipients. I am aware of only two other verifications – UK DX’er Anthony Pearce received a QSL in 1973 and Florida DX’er David Sharp received a verification in 1983.”

Since Dave Sharp noted that his QSL collection was unfortunately lost, the ZOE card I obtained through the eBay auction in 2019 was most likely one received by others in the South African group or possibly by the UK DX’er noted in the 2010 story about Tristan.

The headline out of all of this is that it’s quite possible that other Tristan QSLs are floating around out there.

– Dan Robinson


Wow! Thank you for sharing this follow-up story, Dan!

Readers: Please comment if you have a Tristan Da Cuhna QSL card in your collection! These are rare indeed!

Brazil proposes end of all amateur radio exams (Southgate ARC)

ANATEL, the Brazilian National Telecommunications Agency, recently published a public consultation, CP65, which is available at this link:

In their website, LABRE, the Brazilian Amateur Radio League, was surprised by the CP65 proposal that proposes, among other topics, the extinction of the COER (amateur radio certificate) exam for all classes and replacement by free access to initial class C, as is done today with the Citizen’s Band, as well as access to subsequent classes B and A upon presentation of the Certificate of Technical Course and Graduation in Telecommunications, respectively, or minimum stay of 3 years in each class.

In addition, the aforementioned proposal suggests ending the rules of different prefixes for each of the States of the Federation, remaining only the prefix per class and there would no longer be any special callsigns.

The proposal, in addition to going against what is consensus in the international regulation related to the Amateur Radio Service, is absolutely contrary to the LABRE’s thinking with regard to the minimum requirements to be a radio amateur and also does not match ANATEL’s request for support from LABRE in the revision of amateur radio regulations in Brazil.

For further clarification on the subject, LABRE has already requested a meeting with ANATEL, which will be scheduled soon.

Radio Engineer Files Objection to WIPE (DRMNA.info)

Story by Bennett Kobb:
On September 3, radio engineer Alex Pilosov of Shortwave Solutions filed with the FCC an objection to WIPE, the DRM-based HF station of Turms Tech of New York, presumed to be ready to broadcast from the Armstrong Tower in Alpine, NJ.

WIPE is suspected to be intended mainly for secret, non-broadcast message transmission for private trading clients while broadcasting financial and economic news for the public.

WIPE is not yet operational. The station is waiting on its FCC license, but Pilosov took aim at possible glitches in its license application. He also raises the issue of whether U.S. shortwave stations can legally conduct non-public telecommunications in the broadcast bands in a service limited to broadcasting.

Pilosov is a consultant to HF stations in the Experimental Radio Service, which are not constrained by the broadcast rules; thus he or his clients are prospective competitors to WIPE. This is Pilosov’s second FCC objection. He also filed against the application of Parable Broadcasting for WPBC, a DRM HF station proposed for Batavia, IL.[]

Radio in the Malvinas War (RAE)

In 2020 we celebrate the centenary of radio in Argentina. Such an event can be approached in various ways, since there are several milestones along this century of radio in our country. There are some events that are marked by fire in collective memory.

It is our intention to approach the celebration focusing on an event in which radio was in the spotlight: the 1982 Malvinas War, a conflict waged on various fields: military, economic, diplomatic and, of course, communications, mainly as a means of propaganda.

Most countries over time have recognised the great potential of radio as an effective instrument both in times of war and peace. Historically, Germany was the first country to use this for purely political purposes.

During WWII the broadcasts of Radio Tokyo, Radio Germany, the BBC in London and other stations were used for propaganda and military purposes by combatant nations.

The post-war period and the subsequent Cold War brought along a “war of the airwaves”. During these years, countless stations emerged with their own propaganda styles, looking to advance their social, political and economic systems.

An example of this are the broadcasts of Radio Moscow, Voice of America or Radio Beijing. Along with these stations, others of a clearly political nature emerged, such as Radio Free Europe and Radio Liberty, that targeted countries in Eastern Europe, as well as nations that became independent after the collapse of the Soviet Union. This group also includes the so-called clandestine stations, which generally broadcast secretly from conflict zones or from nearby regions or using rented transmission sites.

Before April 2, 1982, the Malvinas Islands had one radio station: the Falkland Islands Radio Service (FIBS) – with broadcasts in English. Content aired included locally-produced programs as well as news services of BBC London. It broadcast on 536 khz and 2370 khz.

The AM frequency was intended to cover the Port Stanley area, reaching a little further with SW transmissions.[]

Canadian radio stations and TV outlets risk closure (Southgate ARC)

As many as 40 local television outlets and 200 Canadian radio stations could be forced to close in the next three years as the financial pressures faced by media companies intensify under the COVID-19 pandemic, suggests a new study from an industry advocacy group.

The Canadian Association of Broadcasters issued a report on Wednesday warning of potential closures and widespread job cuts as private TV and radio broadcasters face a cumulative projected revenue shortfall of up to $1.06 billion by the end of 2022.

Most vulnerable are the country’s AM radio stations, the report said, as well as other independent private radio and TV operations in smaller markets across the country.

The study, titled “The Crisis in Canadian Media and the Future of Local Broadcasting,” was commissioned by the CAB, which represents the majority of private broadcasters in Canada, and conducted through Winnipeg-based independent media economics consultancy Communications Management Inc.

Bauer closes dozens of regional radio stations in England and Wales (The Guardian)

Replacement of stations with single national outlet described as act of ‘breathtaking cultural vandalism’

Dozens of regional radio stations have been replaced by a single national outlet, in the latest blow to an industry that has seen deep cuts in recent decades.

Outlets across England and Wales owned by Bauer Media – ranging from Wolverhampton’s Signal 107 to York’s Minster FM and Salisbury’s Spire FM – will now broadcast under the single brand Greatest Hits Radio.

Critics said the move was the death knell for traditional mid-sized commercial radio stations, with only a handful of truly independent local radio outlets remaining.

Most of the outlets affected had their own locally employed presenters and management and their own studios in the towns and cities they served. Now, most of the stations on the new network will carry national programming for 20 hours a day.[]

Born at The News: WWJ radio celebrates 100 years since launch as nation’s first commercial broadcaster (Detroit News)

For a behemoth that now dominates the local AM radio dial, its beginnings were surprisingly humble.

One hundred years ago Thursday, WWJ radio — Detroit’s very first station — was born when Detroit News publisher and radio enthusiast William E. Scripps had a 200-watt transmitter set up in a corner of the sports department. (Today? It’s 50,000 watts.) WWJ will air a special show, “WWJ at 100, a Century of News,” at 7 p.m. Thursday to celebrate.

WWJ wasn’t just first in Detroit. Depending on how you slice things, it was the first commercial broadcaster in the U.S., though when it went on the air that Aug. 20 a century back, it was probably picked up by only a few dozen households in possession of what was, at the time, shockingly high-tech radio equipment.

Asked where he’d locate WWJ in American broadcasting history, Specs Howard, founder of the School of Media Arts in Southfield that bears his name, said without hesitation, “Oh, right near the top.”

One-time WRIF program director Fred Jacobs, now head of Jacobs Media Strategies in Bingham Farms, agreed, saying, “It’s really been a remarkable run, especially in a world where brands come and go.”[]

At Voice of America, Trump Appointee Sought Political Influence Over Coverage (KPCW)

At the Voice of America, staffers say the Trump appointee leading their parent agency is threatening to wash away legal protections intended to insulate their news reports from political meddling.

“What we’re seeing now is the step-by-step and wholescale dismantling of the institutions that protect the independence and the integrity of our journalism,” says Shawn Powers, until recently the chief strategy officer for the U.S. Agency for Global Media, which oversees VOA.

Voice of America’s mission is a form of soft diplomacy: to embody democratic principles through fair reporting and to replace a free press in countries where there is none. VOA and its four sister networks together reach more than 350 million people abroad each week.

Since taking office in June, Pack has upended the agency. In a podcast interview last week with the pro-Trump website The Federalist, Pack said he had to take action because many executives and journalists were disregarding the agency’s ethical standards.

“My job really is to drain the swamp, to root out corruption and to deal with these issues of bias, not to tell journalists what to report,” Pack told host Chris Bedford. Pack has declined NPR’s repeated and detailed requests for comment.

But it appears that Pack is, in fact, interested in influencing which stories get told, and how. The senior news editor who oversaw VOA’s standards and practices was reassigned to a corporate position earlier this summer and has since played no role in guiding coverage or scrutinizing stories flagged as problematic.[]
