ABC video highlights the Dooen transmitter on World Radio Day

Standing 201-metres tall with a 19-metre wide capacitive ‘top hat’, the 3WV mast in western Victoria stands out in the vast flat landscape that stretches below it.
Celebrating 75th years of service, the occasion of World Radio Day seemed a worthy time to pay tribute to this impressive technological structure.

“It really meant a lot to us. It must’ve been a big undertaking in 1936 to build it because cranes and things that are about today weren’t even heard of,” says long time Horsham resident James Heard.

And while the locals are proud of the trusty Dooen mast, its power reaches far wider than just this wide brown land.

In fact 594 AM has even been heard as far as Canada, Japan and South Africa.

The staggering reach is aided by the distinctive ‘top hat’ and the low frequency of the AM band. While obviously a success, the antenna was the first of its kind in Australia and acted as a prototype for other services.

“It’s the first solid-state 50-kilowatt broadcast transmitter installed for the ABC and it was the test bed for the installations across the rest of the country,” says Tim Hughes, Transmission Coordinator for ABC Victoria.

So whether you’re tuning in from snowy Canada or just down the road, thanks be to the 3WV transmitter.

I’m sure many an ultralight DXer would like to snag this transmitter! Watch the 3+ minute video on the ABC website.

The Guardian on World Radio Day: celebrating an unsung hero

Radio is the predominant source of information in areas of the world that are sometimes too remote to get a newspaper delivered, let alone access the internet. This is why Unesco has noted that radio is a “low-cost medium, specifically suited to reach remote communities and vulnerable people”.

Attention given to technology for information communications has recently been captivated by web-based applications, especially “new” or “social media”. But about 65% of the world’s 7 billion people do not use the internet. In addition to those who are offline due to lack of access, there are also those who are unaware, unable or simply do not want to use social media.

People listen to the radio in their cars, on the move and at work. Radios don’t require large amounts of electricity, and wind-up radios don’t need an electrical source at all. Moreover, radio reaches large groups of people, being easily shared among families or listener groups. It is a medium often used as a focal point for community discussion on subjects including politics, elections and service provision. Radio efficiently reaches large audiences in real time.

RNW: radio = free access without app or web

Brilliant article from Radio Netherlands Worldwide. Hat tip to SWLing Post reader Mike Taniwha!

(Source: RNW)

On World Radio Day, 13 February 2012, UNESCO will remind the world that there is a medium which reaches parts that other media can’t reach.

Radio is still a vital form of communication because a radio station can be set up much faster, and at much lower cost, than a terrestrial or satellite TV station. Radio is especially useful for reaching remote communities and vulnerable people such as the illiterate, the disabled and the poor. It also provides a platform for such groups to take part in the wider public debate.

Radio also plays a vital role in emergency communication and disaster relief, which was illustrated following the tsunami in the Indian Ocean in December 2004. RNW was able to help several partner stations in Indonesia by sending out “radio stations in a box” – self-contained mobile FM stations providing a temporary studio and transmitter ready to be used by broadcasters whose own facilities had been destroyed.[continue reading…]

Thanks, RNW, for reminding us why radio is the the most effective information medium. Read the full article at Radio Netherlands Worldwide.

Guardian article on “the rise and rise of radio”

Leave a reply

(Source: Susanna Rustin, The Guardian)

What is it about radio that has made it so durable, and able to coexist not only through the age of television, but the age of new media too? As social networking giant Facebook prepares to float itself and raise an astonishing £5bn, what has enabled radio to stand its ground?

[…]Radio can be made at a fraction of the cost of television, meaning that programme-makers, DJs and entrepreneurs can all have a crack at it. Commercial broadcasters as well as the BBC value it as an incubator for future TV talent. Added to which, radios themselves are cheap, and all over the place: by people’s beds, in the bathroom, in the car.

“Despite the fact you think we’re a visually saturated culture, there are all sorts of places where you get radio and nothing else. The technology of radio is cheap, simple and idiot-proof, and older listeners in particular are going to be very reluctant to let it go,” says [Mark] Damazer.

[…]There is a confidence among many of those who work in radio that what they do will carry on. We remain attached to radio and its rhythms, to the hum and the sound of it. And we get attached to the people who present it, when we don’t violently take against them. Radio is personal.

Couldn’t have said it better myself. Another article filed under “why radio?”

Charles Caudill believes in the power of shortwave radio

2 Replies

Charles Caudill, is president & CEO of World Christian Broadcasting. This week, he wrote a piece in Radio World about why his organization still firmly believes in shortwave radio.

(Source: Radio World)

In order to make [our] budget go as far as possible, there is no question that we can reach more people on a regular basis with shortwave than with any other method. With an annual budget of something over $3 million, we will be able to broadcast 50 to 60 hours daily from our two broadcast facilities. Those 50 to 60 hours will be produced by six different services: English, Russian, Chinese, Arabic, Latin American and African.

Obviously, we cannot do everything on that limited budget, but we can literally talk to millions of people using shortwave. We don’t have the luxury of being able to cut $40 million or even $14 million from our budget as some international broadcasters can. Our idea is that God has given us the ionosphere. Our job is to make use of it.

There are millions of analog receivers in the world — some say 600 million, some say 1.5 billion, some say as many as three billion. Regardless of the number, those receivers will not be turned off tomorrow. Those receivers will have listeners for years and years.

Look around; even though technology advances with great rapidity, there are still newspapers. I receive mine every morning. There are still AM radios and FM receivers and they are still making more. And you can still buy books. They are still being published. Even though Amazon is making a fortune selling electronic digital reading devices, they still sell books.

[…]My point is, no medium disappears overnight. Our belief is that shortwave will be here for a long, long time.

Chucho Valdés: Inspiration from VOA Jazz Hours

Leave a reply

(Source: Kim Elliott via the Hartford Courant)

24 Jan 2012, Owen McNally: “Still very much an irrepressible life-force at 70, Chucho Valdés, the renowned Cuban pianist, composer and bandleader, is on a winter tour of the United States that sets down for high-energy maneuvers … at the cabaret series at the University of Connecticut’s Jorgensen Center for the Performing Arts. … The title track [of his new CD], ‘Chucho’s Steps,’ … is a 50-bar adventure in challenging harmony in which he pays tribute to John Coltrane’s intimidating masterpiece, ‘Giant Steps.’ Valdés notes that as a young man in Cuba he would listen on short-wave radio to a program called ‘The Jazz Hour’ on The Voice of America, an experience that opened his ears to Coltrane’s innovations and the creative fervor of the new, iconoclastic music that was fermenting in the States.”

NSA declassifies “Receiver Dynamics” primer

The Watkins-Johnson HF-1000 (and NSA version, WJ-8711) are mentioned in this article

On January 11, 2012 the National Security Agency (NSA) released a pre-1995 article entitled “Receiver Dynamics” from its classified internal magazine, Cryptologic Quarterly. It contains an excellent, well-written explanation of the specifications of shortwave receivers used by some of NSA’s K4 divisions.
