Taiwan: Breaking through censorship via shortwave

Many thanks to SWLing Post contributor, David Iurescia, who shares the following story:

How Taiwan breaches censors’ barriers (VOA News)

Breaking the barriers of censorship in China, Myanmar and North Korea is a daunting task, as these countries have built almost impenetrable firewalls against outside news and information. But Radio Taiwan International is successfully using shortwave radio to break through.

“We potentially have 70 million to 1.2 billion listeners who rely on shortwave to get information [from] outside of their country,” said Isis Lee, RTI’s vice president.

On the air since 1928, RTI say their mission is to bring listeners stories they won’t or can’t hear or see on television, radio, online or in newspapers.

“One of our most important audiences to reach is the Mandarin-speaking society in China, which has very limited internet access,” Lee told VOA. “We have a very big audience in China, and they rely on RTI shortwave service to get perspective outside of China in their mother language,” she added.

Kim Elliott: Why We Need “Shortwave 2.0”

Many thanks to a number of SWLing Post contributors who share the following article written by our friend Kim Elliott for Radio World:

Why We Need “Shortwave 2.0”

by Kim Andrew Elliott

Debate about the future of shortwave broadcasting focuses on the correct observation that shortwave listening is no longer a mainstream activity in most of the world.

The future of shortwave broadcasting — “Shortwave 2.0” — will not involve any revival of those large audiences. Instead, it will be an activity of communications enthusiasts and professionals. They would comprise a reserve corps able to relay information to larger populations in their countries when newer media are blocked or otherwise become unavailable.

The beginning of the end of “Shortwave 1.0” was described in “Shortwave Broadcasting Begins Its Long Slow Fade,” an article I wrote in the 1995 World Radio TV Handbook. I noted the elimination, in the post-Cold-War media environment, of shortwave broadcasts in some languages, as well as some entire transmitting sites, e.g. Trans World Radio on Bonaire and Far East Broadcasting Company in California (KGEI). In my (then) role as audience research analyst at the Voice of America, I listed examples of declining shortwave audiences.

The really big chunk fell from the shortwave glacier six years later, when BBC World Service ended its English broadcasts to North America. In the following years, other international broadcasters followed, first dropping shortwave to North America, and eventually to other parts of the world. The aforementioned 1995 World Radio TV Handbook listed 27 European countries with English broadcasts on shortwave to North America. Now only Radio Romania International has shortwave English to North America.

The exodus from shortwave (for both international and domestic broadcasting) was due to competing media, including relays on FM stations in the target country, satellite broadcasting (mostly television) and, especially, the internet.

For the audience, internet content is easier and more reliable to receive. It also allows content to be received on demand, and text or video in addition to the audio to which shortwave was restricted. As an audience researcher, I could see in the datasets that audiences for international media were migrating from radio to internet-based media. [Continue reading at Radio World…]

Radio Waves: QSL Book, Ham Radio in Taiwan Civil Defense, Radio Silence in Venezuela, and ARRL Handbook 100th Edition

Radio Waves:  Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!


New Book: QSL? (Do You Confirm Receipt of My Transmission?) (Standards Manual)

A collection of over 150 “QSL cards”, QSL? chronicles a moment in time before the Internet age, when global communication was thriving via amateur, or “ham”, radio operators.

Discovered by designer Roger Bova, the distinctly designed cards follow the international correspondence of one ham, station W2RP, who turned out to be the longest-standing licensed operator in The United States.

If China declares war, these ham radio enthusiasts could be crucial (LA Times)

TAIPEI, Taiwan — On Tuesday nights, BX2AN sits near the Xindian River, motionless but for his thumb and middle finger, rhythmically tapping against two small metal paddles. They emit a sound each time his hand makes contact — from the right, a dit, or dot; from the left, a dah, or dash, the building blocks of the Morse code alphabet.
“Is anyone there?” he taps.

The replies come back in fits and starts: from Japan, then Greece, then Bulgaria. Each time, BX2AN, as he is known on the radio waves, jots down a series of numbers and letters: call signs, names, dates, locations. Then he adjusts a black round knob on his transceiver box, its screens glowing yellow in the dark.

There can be no doubt that this is his setup. That unique call sign is stamped across the front of his black radio set, scrawled in faded Sharpie on his travel mug and engraved in a plaque on his car dashboard. On the edge of his notepad, he’s absent-mindedly doodled it again, BX2AN.

In the corporeal world he is Lee Jiann-shing, a 71-year-old retired bakery owner, husband, father of five, grandfather of eight and a ham radio enthusiast for 30 years. Every week, he is the first to arrive at this regular meeting for Taipei’s amateur radio hobbyists.

[…]The self-governing island, about 100 miles east of China, is weighing wartime scenarios in the face of growing military aggression from its vastly more powerful neighbor. If cell towers are down and internet cables have been cut, the ability of shortwave radio frequencies to transmit long-distance messages could become crucial for civilians and officials alike.

Radio silence grows in Venezuela as government shutters dozens of stations (Reuters)

CARACAS, Oct 26 (Reuters) – In July officials from Venezuela’s telecommunications regulator entered the Moda 105.1 FM radio station, in the northwestern state of Cojedes, accompanied by members of the national guard and demanding to see all the station’s licensing.

Hours later they stopped it broadcasting – making Moda one of at least 50 stations in Venezuela’s interior which have been closed so far this year by the Conatel regulator because it says they lack valid licenses.

The accelerated closures are a new step in efforts by the government of President Nicolas Maduro to control information and give state media hegemony over communications, journalist guilds and non-governmental organizations say, continuing a policy begun under his predecessor Hugo Chavez.

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!


The Termination Event has Arrived (Space Weather Archive)

Feb. 26, 2022: Something big just happened on the sun. Solar physicists Scott McIntosh (NCAR) and Bob Leamon (U. Maryland-Baltimore County) call it “The Termination Event.”

“Old Solar Cycle 24 has finally died–it was terminated!” says McIntosh. “Now the new solar cycle, Solar Cycle 25, can really take off.”

The “Termination Event” is a new idea in solar physics, outlined by McIntosh and Leamon in a December 2020 paper in the journal Solar Physics. Not everyone accepts it–yet. If Solar Cycle 25 unfolds as McIntosh and Leamon predict, the Termination Event will have to be taken seriously.

The basic idea is this: Solar Cycle 25 (SC25) started in Dec. 2019. However, old Solar Cycle 24 (SC24) refused to go away. It hung on for two more years, producing occasional old-cycle sunspots and clogging the sun’s upper layers with its decaying magnetic field.  During this time, the two cycles coexisted, SC25 struggling to break free while old SC24 held it back.

“Solar Cycle 24 was cramping Solar Cycle 25’s style,” says Leamon. [Continue reading…]

The tiny radio station broadcasting Russian propaganda in D.C. (Washington Post)

For a few seconds every hour, WZHF-AM interrupts its round-the-clock schedule of talk to air a curious disclaimer: “This radio programming is distributed by RM Broadcasting on behalf of the Federal State Unitary Enterprise Rossiya Segodnya International Information Agency, Moscow, Russia. Additional information is available at the Department of Justice, Washington, D.C.” Continue reading

RadioWorld: Radio Reaches Blocked Countries

(Source: RadioWorld via Southgate ARC)

International radio remains the most reliable, robust source of information for people in some nations

North Korea is rated as the second most censored county in the world after Eritrea, according to the Committee to Protect Journalists.

North Koreans who are caught accessing information not approved and disseminated by the government can be sent to brutal prison camps for extended terms, or face execution.

Yet such is the human hunger for reliable outside information, that many North Koreans brave these risks by tuning into international radio and cross-border TV broadcasts wherever practical.

Many also watch banned South Korean TV programs on black market DVDs, SD cards, and USB sticks; plus computers and mobile phones smuggled in from China. (South Korean movies and soap operas are hugely popular in the North, according to the New York Times.)

The conclusions they draw from this content are subsequently shared with other North Koreans by word-of-mouth; despite the fact that such sharers can get in serious trouble with the Kim Jong-Un regime.

Remembering Radio Beijing: 25th anniversary of the Tiananmen Square massacre

Today is the 25th anniversary of the horrible events that took place in Beijing’s Tiananmen Square on June 4, 1989, during which Chinese troops opened fire on unarmed student demonstrators.

In this off-air shortwave radio recording of Radio Beijing, made on June 3rd, 1989, you’ll hear the news reader/editor depart from the script and comment on the massacre of protestors in Tiananmen Square:

It’s believed this brave news editor was detained shortly after the broadcast and spent years in a detention (re-training) camp.

Rest assured, you will hear no mention of the Tiananmen Square protests on China Radio International today–even though this year marks the 25th anniversary of the event. China’s state media goes to great lengths to keep this sort of on-air protest from happening again. State media even tries to limit on-line research of the protests; last year, we posted a fascinating article which listed banned search engine terms in China.

I also encourage you to check out Jonathan Marks’ comments (from a broadcaster’s perspective) on this particular Radio Beijing broadcast.

The 24th Anniversary of Tiananmen Square

Tiananmen Square_man_blocks_tank_238Yesterday, I had two reminders of how important shortwave radio is in China.

The first was this incredible recording shared by David Goren–an unidentified Radio Beijing announcer who departed from the script and commented on the massacre of protestors in Tiananmen Square in 1989. It’s believed this announcer is still imprisoned:

The second was an article that a journalist friend had posted. It’s simply a list of search terms that the Chinese government blocked on Sina as of June 4th. Of course, the list contains words you would assume would be included, like: 1989, 89, vigils, and memorial ceremony. But it also includes words like: Internet block, sensitive word, and inappropriate for the public. Think of how many sites and posts this blocked (certainly ours!). Of course, there are many more terms on the list–check out this article on China Digital Times for more information.

So why is shortwave radio still important in China? It’s impossible to block those search terms on radio.
