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!

Many thanks to SWLing Post contributors Mike Terry, Dan Robinson, Ulis Fleming, and William Lee for the following tips:


Switzerland Inches Closer to FM Switch-Off (Radio World)

GENEVA — Switzerland is embarking on the next phase of its digital radio switchover strategy. In May René Wehrlin, media specialist at Switzerland’s Federal Office of Communications (Ofcom) announced the country’s next steps toward the country’s total transition to DAB+.

Ofcom officially confirmed in 2019 that the nation would say “adios” to all FM radio programs by the end of 2024 at the latest. At the time, the “Digital Migration” (DigiMig) working group, set up by the Swiss private and public radio sectors and Ofcom in 2013, stated that 68% of radio listening was digital, 37% of which was via DAB+ and 15% exclusively via FM.[]

Guyana refuses US’ request to facilitate radio broadcasts to Venezuela (Demerara Waves)

Guyana’s President David Granger late Friday said his administration rejected a request by the United States (US) to use the medium wave radio frequencies of this South American nation to broadcast Voice of America programmes to Venezuela.

Mr. Granger said Guyana turned down the request because of security, health and political risks that Guyana could expose itself to with Venezuela which is claiming the Essequibo Region that makes up about two-thirds of this former British colony.

“Given the length of an unpoliced western border, the influx of refugees, the unsettled territorial question and the public health risks, it would not be in our national interest to do anything to contribute to destabilising relations at this time,” the President said.

A US Embassy spokeswoman said the American government was no longer interested in the project. ” The U.S Agency for Global Media is not actively considering this anymore. It is important that the people of Venezuela have access to uncensored news from credible Venezuelan and international journalistic news sources. Guyana has shown leadership in the past, in defense of representative government by joining other Lima Group members from the Americas to strive for a democratic resolution to the crisis in Venezuela,” she said.[]

Close encounter between US-China militaries captured by radio amateur (South China Morning Post)

The Chinese navy has warned off a US military plane that briefly flew close to the southern coast of China, north of the Taiwan Strait, according to a Beijing-based think tank.

In a 34-second scratchy radio recording released by the South China Sea Strategic Situation Probing Initiative (SCSPI), a think tank based in Beijing, a man – purported to be a Chinese naval official – can be heard saying in English: “This is China Naval Air Force on guard, you are approaching Chinese air domain, change your course immediately or you will be intercepted.”
He then repeated the warning in Mandarin Chinese.

The institute said on its Twitter account that the recording was captured on Thursday morning by a radio amateur. It remains unclear which aircraft was involved, or if there was any face-off in the air.[]

Charity Intelligence recommends Farm Radio International (Charity Intelligence)

Charity Intelligence is recommending donors support Farm Radio International for the coronavirus pandemic. Farm Radio has a network of over 1,000 radio programs reaching more than 250 million people in 41 countries across Africa.

To donate to Farm Radio’s covid-response

Communication is critical in the early stages of a disease outbreak to give people information. Rumours swirl that Africans cannot get coronavirus. Tanzania’s president, Magufuli, said churches should stay open because the coronavirus is “satanic” and “cannot survive in the body of Christ.” As all have witnessed, fake news has harmful consequences with the quick coronavirus.

Farm Radio International is a Canadian, medium-sized charity with donations of $3.9m in 2018. Typically, a charity of this size would not be front of mind in a global response. Yet Farm Radio has the existing platform and local operations to play an effective role reaching millions quickly in a coronavirus response. Early communication is an urgent need. []

Pentti Stenman’s impressive collection of SWL recordings, QSLs, and pennants

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

Just ran across this guy’s site Pentti Stenman, who is in Finland.
Check out his audio and QLS, pennants as well…

http://www.penan.net/dx-kuuntelu

Pentti’s collection is impressive indeed! Since he’s in Finland, some of his site is in Finnish, but it’s still quite easy to navigate and you can have Google translate it into any language.

I have pasted direct links below to Pentti’s various galleries.

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!

Ernest Eugene “Gene” Pell 1937-2020 (Radio Free Europe)

As noted in this obituary published by his hometown newspaper, The Paducah Sun, Ernest Eugene “Gene” Pell, 83, died quietly on April 7, 2020, at his home near Syria, after a 3-year battle with cancer. Pell served as President and Chief Executive Officer of Radio Free Europe/Radio Liberty (RFE/RL) from 1985-1993, leading the Radios during the peaceful revolutions that occurred in Eastern Europe and the Soviet Union from 1989-1992.

In Tribute to Gene Pell

In 1989, we who were privileged to serve in the management of RFE/RL as Gene Pell’s colleagues watched the awesome professionalism of RFE/RL’s broadcasters as peaceful revolution swept from the Baltics to the Balkans, and the Radios helped each country share with others the power – even the slogans – of peaceful protest, and the wisdom of restraint by police and armed forces.

Romania was a tragic exception. Ceaucescu’s regime was doomed by RFE’s broadcast of a recording of the shooting of civilians protesting in Timisoara. As Ceaucescu fled Bucharest, and violence by unknown combatants erupted, Gene ordered a million watts of shortwave power from our transmitter stations across Europe diverted to the Romanian service. Before long, Romanian army commanders seeking to restore calm established phone contact with the service in Munich.

In the immediate aftermath of the liberation of Eastern Europe, and the 1991 collapse of the Soviet Union, Gene saw the need and found the resources to open bureaus across the region and begin on-the-ground reporting by talented local journalists – and local rebroadcasting of RFE/RL programming.

And he persuaded the U.S. government to allow RFE/RL for the first time to broadcast to the former Yugoslavia, during the Bosnian War, with a new, multi-ethnic service led by Nenad Pejic*.

On Gene’s watch, Lennart Meri, Foreign Minister of a newly free Estonia, nominated RFE/RL for the Nobel Peace Prize.

Gene’s leadership was crucial as another struggle soon ensued, this time in Washington, as efforts arose to save the federal government money by shrinking or closing the Radios, on the premise that if Europe was free, why did we need Radio Free Europe (and Liberty)? Support from new democratic leaders across the region, notably from Lech Walesa and Vaclav Havel, helped convince a Presidential Commission addressing this question that the Radios’ mission should not end but evolve, as it has.

The views of these freedom leaders were decisive in keeping RFE/RL on the air and positioned to win the enormous multi-media audience it enjoys today. Gene Pell’s vision is alive for future generations.

Two of my closest colleagues, Ross Johnson and Kevin Klose, join me, as I am sure many others would, in saluting Gene for his contribution to a freer world.

A Dangerous Demonstration of the Power of Radio (Hackaday)

Terrestrial radio may be a dying medium, but there are still plenty of listeners out there. What would a commute to or from work be without a check of “Traffic on the Eights” to see if you need to alter your route, or an update of the scores from yesterday’s games? Getting that signal out to as many listeners as possible takes a lot of power, and this dangerous yet fascinating demo shows just how much power there is on some radio towers.[]

White House Criticism of VOA, Unprecedented in its 78 year History (Public Diplomacy Council)

The Voice of America is the nation’s largest publicly-funded international broadcaster, reaching 280,000,000 multimedia users in 47 languages each week, many of whom access it daily for honest, balanced and accurate world news.

To most senior VOA officials, past and present, including this writer, an unsigned White House blog on April 9, 1600 Daily, omitted or misstated vital information about the scale and original date of the coronavirus outbreak in mainland China. That blog asserts in a bold headline: “Voice of America spends your money to speak for authoritarian regimes.”

But that attack was just the beginning.

President Trump went even further at his daily news briefing on April 15, largely devoted to the coronavirus. “If you heard what’s coming out of the Voice of America, it’s disgusting”. The President then assailed Congress for failing to take up his nomination of conservative Michael Pack as chief executive of all five U.S. funded multimedia organizations, the U.S.Agency for Global Media, until recently known as the U.S. Broadcasting Board of Governors.

The USAGM is the oversight body of five overseas multimedia U.S.-funded networks: VOA, Radio Free Europe/Radio Liberty, Radio Free Asia, the Middle East Broadcasting Network in Arabic, and Radio/TV Marti in Spanish to Cuba. Research in approximately 100 countries indicates that collectively, the five networks reach 350,000,000 people abroad every week.[]

Video: Antonio’s Kenwood R-2000 Modifications

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

Antonio Fernandez, who is in Spain, posted this on the Extreme page. Very interesting R-2000 mods:

Major modifications are adjustable RF GAIN (using the former TONE control), BFO Pitch control (former AM Squelch, FM Squelch is retained) and DSP Audio filtering for SSB and CW. Internal DSP module is SOTABEAMS Laserbeam Filter Module. The former DIMMER and NB push switches are used for switching on (bypassing) the DSP module and bandwidth (CW, SSB) selection.

Those are brilliant modifications on a classic receiver!  Thank you for sharing, Dan!

Tecsun PL-990: How to distinguish pilot run and final export versions

The Tecsun PL-990

As I suspected, it appears the Tecsun PL-990 batch that showed up recently on AliExpress for $399 each are the preliminary pilot run units that Tecsun offered in China last year. The final export version of the PL-990 is not ready for production yet and has been severely delayed by Covid-19 quarantines.

Anna at Anon-Co reports that Tecsun factories have been closed since mid-January 2020 and have only recently recommenced production, “but at a very slow pace.”

Since there will eventually be two different versions of the Tecsun PL-990 in the wild–the pilot run for China, and the finalized export version–I thought I’d share a trick Anna has described to tell the difference between the two.

Anna notes:

One way to easily see this is from the labels for the buttons above the keypad, these should be

[ TIME ], [ TIMER A ], and [ TIMER B ] (see picture below)

Tecsun PL-990 Final Export Version:

Tecsun PL-990 Final Export version

Tecsun PL-990 Final Export Version

Pilot Tecsun PL-990 (preliminary China domestic version):

Preliminary Pilot Tecsun PL-990 distributed in China — image from AliExpress.

Anna adds:

I highly recommend [no one] buy these pilot versions, because the software on those devices is also not developed.

There still isn’t a final version or any price indication available yet, but it will definitely not be US$399.99.

So in case it’s not clear: don’t purchase a PL-990 until you can confirm you’re receiving a final export version which has the TIME, TIMER A, and TIMER B labels.

Again, at time of posting, the final PL-990 export version is not yet in production.

When the final export PL-990 is available, I will announce it here on the SWLing Post with links to authorized retailers like Anon-Co.
