VKS-737 Australian HF Communications services for travellers

Many thanks to SWLing Post contributor, Jerome van der Linden, who writes:

At the Adelaide Caravan & Camping Show this last weekend, I picked up a brochure outlining the services of the VKS-737 HF Radio Network operated by a Public Benevolent Institution Established in 1993.

Its mission statement is to provide emergency and general radio communications assistance services to travellers in rural and remote areas of Australia using Base stations located in Adelaide, Alice Springs, Cairns, Carnarvon, Charleville, Charters Towers, Darwin, Derby, Meekatharra, Mount Isa, Newcastle, Perth, Port Hedland, St Marys, and Swan Hill. Some of these stations are Royal Flying Doctor base stations.

The brochure details the Channels / Frequencies used as follows: 1: 5,455kHz; 2: 8,022; 3:11,612; 4: 14,977; 5: 3,995; 6: 6,796, and 7: 10,180kHz

The VKS-737 web site also has an interesting and at times humorous example of a couple of videos showing travellers making use of the system.

Apparently, apart from licensing requirements, the equipment required is not cheap, being in the order of AU$3,800 to $4,300. I think the equipment is made by Codan. The brochure also makes the point that HF radio can be used for entertainment such as to receive BBC World Service and Radio New Zealand. Clearly, the group is up to date in being aware that Australia’s own short wave broadcasting services are now – regrettably – a non event.

Thank you for sharing this, Jerome! I’ve heard of the VKS-737 service, but did not realize their network was so robust and that it piggybacks on a portion of the Royal Flying Doctor network.

Post readers: Anyone here familiar with the VKS-737 network?  Have you ever used the system  Please comment!

United Nations: Radio still a powerful worldwide tool for ‘dialogue, tolerance and peace’

Post-earthquake, Ears To Our World radios continue to be a vital link for those in need in Haiti. Here, Erlande, who suffered a stroke in her early 30s and can barely walk, listens to one of our self-powered Etón radios. (Photo: ETOW)

“Even in today’s world of digital communications, radio reaches more people than any other media platform” explained the UN chief, adding that it “conveys vital information and raises awareness on important issues”.

“And it is a personal, interactive platform where people can air their views, concerns, and grievances” he added, noting that radio “can create a community”.

UN Radio was established on 13 February 1946, and since 2013, the day has been commemorated to recognize radio as a powerful communication tool and a low-cost medium.

“For the United Nations, especially our peacekeeping operations, radio is a vital way of informing, reuniting and empowering people affected by war”, said Mr. Guterres.

Despite the rise of the internet, many parts of the world, especially remote and vulnerable communities, have no access, making radio broadcasting via transmitters, a vital lifeline. Joining a community of local listeners, also provides a platform for public discussion, irrespective of education levels.

Moreover, it has a strong and specific role in emergency communication and disaster relief.

“On this World Radio Day, let us recognize the power of radio to promote dialogue, tolerance and peace”, concluded the Secretary-General.

Radio still sparking ‘new conversations’

The UN Educational, Scientific and Cultural Organization (UNESCO) underscored “the unique, far-reaching power of radio to broaden our horizons and build more harmonious societies”.

“Radio stations from major international networks to community broadcasters today remember the importance of radio in stimulating public debate, increasing civic engagement and inspiring mutual understanding”, UNESCO Director-General Audrey Azoulay said in her message.

Since its invention as the first wireless communication medium well over a hundred years ago, “radio has sparked new conversations and broadcast new ideas into people’s homes, villages, universities, hospitals and workplaces,” she continued. “To this day, dialogue across the airwaves can offer an antidote to the negativity that sometimes seem to predominate online, which is why UNESCO works across the world to improve the plurality and diversity of radio stations”.

The UNESCO chief pointed out that radio has adapted to 21st century changes and offers new ways to participate in conversations that matter, retaining its role as “one of the most reactive, engaging media there is”, especially for the most disadvantaged.

For example, she flagged that rural women constitute one of the most under-represented groups in the media and are twice as likely as men to be illiterate, “so radio can be a critical lifeline to express themselves and access information”.

Ms. Azoulay made clear that “UNESCO provides support to radio stations in sub-Saharan Africa that enable women to participate in public debate, including on often-neglected issues such as forced marriage, girls’ education or childcare”.

Linguistic diversity, and people’s right to express themselves on-air in their own languages, is also crucial – especially true in 2019 which has been designated by the International Year of Indigenous Languages by the UN.“In former conflict zones, radio can dispel fear and present the human face of former foes”, she elaborated, citing North-West Colombia where community radios are healing old wounds “by highlighting the good deeds of demobilized combatants, such as clearing polluted waterways”.

Around the world, the “inclusion of diverse populations makes societies more resilient, more open and more peaceful”, Ms. Azoulay spelled out.

“The challenges we face – whether they be climate change, conflict or the rise in divisive views – increasingly depend on our ability to speak to each other and find common solutions”, she concluded.

End of WWV weather information

Photo taken in 2014 of the sign above WWV’s primary 10 MHz transmitter.

Many thanks to SWLing Post contributor, Richard Langley, who writes:

As monitored here in NB on 15 MHz today (31 January), WWV ended the National Weather Service Atlantic and Pacific marine high-seas and storm warnings after 19:00 UTC. Before that time, announcements about the ending of the warnings were transmitted during minutes 4 and 7 after the hour with the Atlantic information in minutes 8 and 9 and the Pacific information in minute 10. So, the last storm warnings were during the 18:00 UTC hour. After 19:00 UTC, the announcements in minutes 4 and 7 were discontinued and the storm warnings in minutes 8, 9, and 10 were replaced with an announcement about the ending of the warnings. Presumably, there was a similar transition on WWVH.

Thanks for the report, Richard!

In terms of an overall update about WWV in the 2019 NIST budget, there has been no real news to report. It seems the funding level for the Laboratory Programs (where the radio stations reside) will be funded at the same level as it was in 2018. Of course, NIST can internally-allocate many of their funds as they wish. Many thanks to SWLing Post contributor, Richard Cuff, who’s been keeping an eye on this budget process.

I must admit that I find it interesting WWV, WWVH and WWVB all continued to operate as normal during the Federal Government Shutdown.

RTÉ longwave 252: maintenance shutdown June 27 – July 8, 2017

Many thanks to SWLing Post contributor, James Leary, who shares the following news and audio clip from RTÉ:

Hi Thomas, I heard this announcement the other day about RTE 252 and thought it might be of interest for your site. I think it’s also going to shut down permanently in 2019.

Received on a Tecsun PL-390 in NW UK.

Click here to download the audio as an MP3.

Thanks for the news and recording, James!

You’re correct: according to an article from Radio Today, RTÉ has agreed to continue its longwave 252 service until the end of June 2019.

Impressive that RTÉ’s longwave transmission equipment has been in continuous operation for over 27 years! I’m not surprised the antenna needs maintenance.

Video: Icom IC-R8600 sync detector in action

Many thanks to SWLing Post contributor, Dave Zantow (N9EWO), who shares the following:

For your listening pleasure. Here is the best video yet showing the Icom IC-R8600’s Sync Detector in use.

Sounds like Icom “finally” got the Sync Detector performance right with the R8600. Appears to greatly reduce fading distortion, where as with the expensive IC-R9500 it does not help much with fading distortion (if at all).

Click here to view on YouTube.

Good news indeed !!

I agree, Dave. This is most promising indeed!

I look forward to checking out the IC-R8600 at the Dayton Hamvention this year.

The Eleventh HOPE Conference

HOPE-2016

Many thanks to SWLing Post contributor, Ed, who writes:

You might consider reporting on The SWLing Post that there will be several talks at the The Eleventh HOPE conference this Fri/Sat/Sun that might interest your readers, including:

Tuning in to New York City’s Pirates of the Air

David Goren

Pirate radio in New York City is a homegrown cultural phenomenon that is at once aesthetically vibrant, technologically tumultuous, and undeniably illegal. Emanating from clandestine studios and hidden transmitters, the sounds of Kreyol, Yiddish, Spanish, and Caribbean-accented English waft into the urban atmosphere. On an average night in Flatbush, Brooklyn, it’s not uncommon to be able to hear as many as three dozen pirate stations between 87.9 and 107.9 Mhz. This flowering of outlaw micro-radio stations in Brooklyn and throughout the greater New York City region is a major disruption to the status quo of corporate controlled, robo-playlisted mega stations. Their unregulated presence and programming often reflects the throb and hum of a diverse city more authentically than traditional media outlets. Join radio producer David Goren for an audio tour of these stations featuring the music, programs, and personalities that make up New York City’s pirate radio scene.

Monitoring Dusty War Zones and Tropical Paradises – Being a Broadcast Anthropologist

Mark Fahey

Tuning in distant foreign radio and television stations is a conduit to unique and exotic information. These signals are often confronting, uncensored, and unsanitized. In the western world, we blur or pixelate images of death and torture, but signals from war zones or rebellions show tragedies happening live on the air. Other signals broadcast the joy of life on this planet through exotic song, music, and film. Digital wide-band recordings of the electromagnetic spectrum allow virtual time travel, a form of mental teleportation whereby recorded spectrum is tuned to hear stations as if they were being tuned in real time. Take a virtual tour of Mark’s monitoring station in Sydney, Australia which is wired to access the world’s mass media via whatever delivery conduit is needed to capture the content. The station receives hundreds of thousands of inbound digital audio and video channels that let him monitor domestic radio and television from most parts of the world. If he wants to watch breakfast television from Tibet, or maybe the nightly news from the remote Pacific islands of Wallis and Futuna, then it’s available in perfect studio quality. You’ll also see his visits to remote broadcasters and rare, uncensored video from telejournalists that captures the tragedies and joy served up by our planet.
