Radio World: “The Internet’s Impact on International Radio”

The Edward R. Murrow Transmitting Station Control Room

Many thanks to SWLing Post contributors, Dennis, Eric, and Michael who share the following story from Radio World. Please note my comments below following a short excerpt from this piece:

OTTAWA — During the height of the Cold War (1947–1991), the shortwave radio bands were alive with international state-run broadcasters; transmitting their respective views in multiple languages to listeners around the globe.

The western bloc’s advocates were led by the BBC World Service, and included Voice of America, Radio Liberty/Radio Free Europe, Radio Canada International and a host of influential European broadcasters. The eastern bloc’s de facto team captain was the USSR’s Radio Moscow (with its unique hollow, echoing sound), supplemented by broadcasters in Soviet satellite countries (like East Germany’s Radio Berlin International) and allies like Fidel Castro’s Radio Havana Cuba.

Then 1991 arrived, and the Cold War apparently ended with the fall of the Soviet Union and the destruction of the Berlin Wall.

In the seeming peace that followed, many governments no longer saw the sense in spending millions on multi-megawatt transmitters and vast antenna farms to keep broadcasting their messages globally.

The leader among them, the BBC World Service (BBCWS), trumpeted the web and webcasting as modern, cost-effective alternatives to expensive shortwave broadcasting (along with satellite radio and leasing local FM airtime in the countries they used to broadcast to). This is why the BBCWS ceased shortwave transmissions to North America and Australia in 2001 and Europe in 2008, while retaining SW broadcasts in less-developed parts of the globe.[…]

The full article is available here and quite a good piece exploring how the Internet has had an impact on shortwave radio broadcasting.

I, along with a number of fiends in the shortwave community–Bob Zanotti, Jeff White, Colin Newell, and Ian McFarland to name a few–we’re quoted in this piece.

As with most any published piece, quotes and statements are trimmed and edited to fit the print space. If you read the full article, you will have noticed some quotes from me. Here’s a larger portion of my full statement for this piece:

Most audience analysts agree that the number of shortwave listeners has been on the decline at the same time Internet access has been on the rise. Moreover, shortwave listener numbers are hard to quantify due to the very nature of anonymous listening; no one can truly “track” a shortwave radio listener. On the other hand, there is nothing anonymous about those who listen to or watch Internet content–not only can the audience be measured by numbers, but a much deeper and more invasive set of data can be gleaned from an online audience. Thus the decline in shortwave also denotes a loss of anonymity on the part of the listener.

This is not to say there aren’t shortwave listeners. A significant number of listeners are radio enthusiasts/DXers who appreciate the shortwave medium. But perhaps more meaningfully, shortwave listeners are those living in rural and remote parts of the world who benefit from the instant, free, and anonymous information shortwave provides.

At Ears To Our World, we received this photo from a school in rural Tanzania in June 2019. The teacher has been using one of our self-powered shortwave radios to listen to news and improve language skills.

Some broadcasters effectively target both of these audiences. Large government broadcasters, however, have always tried to reach the “influencers” in a country–those who might eventually help guide a country’s policy and international relationships. And the great majority of these influencers, according to audience research, have moved to social media and the Internet as a source of information.

Note that I received the photo above in June. At Ears To Our World, we still work with communities that appreciate the accessibility of radio. Perhaps our partners are more the exception than the rule, but there are still those who benefit from radio–especially those living in rural and remote areas. Where large government shortwave broadcasters are pulling out of the scene, often community-driven stations are taking their place. We’ve been working with Radio Taboo in Cameroon, for example, and they are an amazing case in point.

As a radio enthusiast, I’ll also add that I love the homegrown nature of shortwave broadcasting these days. As private broadcasters have a larger market share of the airwaves, individuals have an opportunity to buy their own broadcast time and produce amazing, unique shows like VORW, Free Radio Skybird, Encore, From the Isle of Music and Uncle Bill’s Melting Pot. These are just a few examples–if you’d like more, just check out the latest edition of Alan Roe’s guide to music over shortwave.

VOA exhbition: “a fascinating look at early shortwave radio”

Many thanks to SWLing Post contributor, George Herr, who shares the following item from the LA Times:

Long before cell towers started sprouting up everywhere, the federal government commissioned telecommunication companies to build five massive fields of shortwave radio antennae. The structures, which reached up to 450 feet, were located in out-of-the-way places in California, Ohio and North Carolina. Each was designed to bounce radio waves off the ionosphere, allowing federally produced programming to be transmitted all over the globe.

The U.S.’ international radio broadcaster Voice of America was born during World War II. It expanded during the Cold War. As technology advanced, its programs were carried via television and digital platforms. Today it is part of the U.S. Agency for Global Media, providing news and information in 50 languages to a weekly audience of 275 million.

Its early years are traced in a fascinating exhibition at the Center for Land Use Interpretation in Culver City. “Voice of America: The Long Reach of Shortwave” takes visitors back to the predigital world, before our political leaders began tweeting their innermost sentiments and policy decisions. Back then, international audiences were addressed more formally, via carefully scripted programming.

[…]The antennae are the stars of the show. They appear in photographs, in videos and on touch-screen monitors. Arranged in grids, arcs and asymmetrical arrays, they resemble high-tech fishing nets, impossibly spindly bridges, supersized spirit catchers and otherworldly telephone poles. Sculpturally impressive, they make Land Art look fussy, precious and small.

All but one of the five transmission stations have been abandoned. The most haunting component of the exhibition is a three-minute video documenting the destruction of the antennae. In sequence after sequence, little puffs of smoke appear before the towering antennae yield to the tug of gravity and topple to the earth in seemingly slow motion. Some crash into others, causing them to fall like skyscraper dominoes. It’s a sad ballet that marks the end of an era.

A pair of touch-screen slideshows is also bittersweet. It takes visitors on a virtual tour of Transmission Station B (the only one still functioning) and Transmission Station A (its twin). Both are near Greenville, N.C. To see the up-and-running station alongside its vandalized, disused doppelganger is to glimpse a living world next to a dying one.

Both are ours.

Radio World: “Radio’s Essential Role in Asia”

Many thanks to SWLing Post contributor, Marty, who shares the following article from Radio World:

STOCKHOLM — Radio is part of the lives of people around the world. In Asia this can amount to where hundreds of millions of listeners who tune in every day. Radio is a strong, inexpensive and effective medium to reach mass audiences.

Many of the challenges facing traditional radio elsewhere in the world are about to hit Asia. These include the expansion of music streaming services and ad investments being divided among other platforms such as social media. But the structure and maturity of the region’s radio industry differs a lot.

[…]Private radio is fairly new to many countries in Asia. India is one such example, where programs are mainly music-based and stations are still developing their brands and formats. Also, there is little standardization in tracking listening habits in many Asian countries and many groups tend to rely on their own figures. This leads to confusion for agencies that want to know what radio can deliver.

Public-service media is often closely monitored and controlled by government. But entertainment, music and sports offer broadcasters the potential to build strong radio brands they can further expand into social media, events and other activities. Something many are now exploring.

There are also new, more speech-based stations, such as business stations in Singapore and Kuala Lumpur. A particular strength for radio is its closeness to its audience, in many countries manifested by stations broadcasting in the various local languages. This is also true for community radio, which are vibrant and widespread in parts of Asia, especially India, Nepal and Bangladesh.

Radio plays an important role when natural disasters strike, frequently making the difference between life and death for millions of people. It’s often the only way of conveying information, be it earthquakes in Nepal, storms in the Philippines or tsunamis in Japan.

Radio´s easiness to use is an asset, but radio sets in homes are not as common as you might expect. FM radio saw a rise in listenership in India when nearly everyone had a mobile phone with built-in FM receivers. But today with new mobile phones coming into the market without FM, there is a new challenge. Will internet audio in phones lead the way to podcasting, as in the west? Or will Spotify and music streaming´s personalized offers replace traditional radio listening?[…]

New Silicon Labs automotive radio tuners support DRM and built on “SDR-friendly technology”

Many thanks to a number of SWLing Post readers who shared this latest press release from Silicon Labs. This is certainly a major upgrade to the Silicon Labs line of tuners/DSP chips. Native Digital Radio Mondiale (DRM) support will, no doubt, meet the needs of car manufactures in countries (like India) that have adopted DRM rather than HD radio and DAB/DAB+.  Of course, perhaps this might lead to an affordable DRM portable in the future:

Silicon Labs enhances Si479xx automotive tuner family with software-defined radio (SDR) technology.

(Source: Silicon Labs)

AUSTIN, Texas, July 29, 2019 /PRNewswire/ — Silicon Labs (NASDAQ: SLAB), a leading provider of automotive radio solutions, has introduced new hybrid software-defined radio (SDR) tuners, expanding its portfolio to meet the growing need of automotive radio manufacturers to support all global digital radio standards with a common platform. The new Si479x7 devices are Silicon Labs’ first automotive radio tuners supporting the Digital Radio Mondiale (DRM) standard. The Si479x7 tuners are an extension of Silicon Labs’ popular family of Global Eagle and Dual Eagle AM/FM receivers and digital radio tuners, providing the same outstanding field performance, pin and package compatibility between single and dual tuners, and bill of materials (BOM) cost advantages.

In addition to introducing new DRM-capable tuners, Silicon Labs is enhancing its Si4790x/1x/2x/5x/6x automotive tuners with unique “SDR-friendly” technology, effectively transforming these devices into hybrid SDR tuners. Silicon Labs’ hybrid SDR technology includes advanced DSP-based automotive features such as Maximal Ratio Combining (MRC), Digital Automatic Gain Control (AGC), Digital Radio Fast Detect and Dynamic Zero-IF (ZIF) I/Q. These features enable automotive radio manufacturers to support global digital radio standards with a common radio hardware and software design. This added flexibility helps OEM and Tier 1 customers reduce design, qualification, sourcing and inventory costs while avoiding the complexity and inefficiency of supporting multiple automotive radio platforms.

“Silicon Labs’ automotive tuners with hybrid SDR capabilities deliver the highest integration and reception performance and the lowest BOM cost of any automotive SDR tuners in mass production today,” said Juan Revilla, General Manager of Broadcast Products at Silicon Labs. “Our tuners with advanced digital radio features enable radio manufacturers to develop a single platform to demodulate and decode worldwide digital radio standards, greatly simplifying car radio designs and reducing system cost.
