Radio Waves: Radio Marti DRM, Push for Shepparton Museum, APRS on the History Channel, and Radio’s “Major Cultural Opportunity”

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 Alan Hughes, Michael Bird, Zack Schindler, and Dennis Dura for the following tips:


Radio Marti Begins Shortwave DRM Transmissions (Radio World)

Radio Marti began Digital Radio Mondiale (DRM) shortwave transmissions on Feb. 4. Part of the U.S. Agency for Global Media (USAGM), Radio Marti broadcasts news and other programs to Cuba. The DRM shortwave transmissions are from USAGM’s Greenville, North Carolina, site.

USAGM has transmitted in DRM before. There were some transmissions from Briech, Morocco, in the early 2000s. Greenville tested DRM in 2009 in partnership with what was then known as HCJB Global Technology. So why are they back now after an absence of over a decade?

“We want to experiment a bit with different modes and services available on DRM. We also want to help push the development of low-cost receivers and the best way to do that is to put some transmissions on the air, explains Gerhard Straub, director of USAGM’s Broadcast Technologies Division.[]

Push for museum at Shepparton’s Radio Australia site (Shepparton News)

Amateur radio enthusiasts are pushing for the former site of Radio Australia in Shepparton North to be upgraded and retained as a national museum of radio broadcast history.

Members of the Shepparton and District Amateur Radio Club and The Vintage Radio Club of North East Victoria are due to present a 25-page proposal to an anonymous consortium of buyers said to be interested in acquiring a 258ha block of land along Verney Rd.

The block includes two buildings and several large broadcast towers on the former site of Radio Australia. The site is currently owned by BAI Communications.

The Shepparton club’s assistant secretary, Geoff Angus, said the proposal would be presented to Greater Shepparton City Council for forwarding to the consortium.[]

APRS usage seen on the History Channel “Secret of Skinwalker Ranch”

Zack Schindler writes:

I have been watching a show about paranormal activity on the History Channel called The Secret of Skinwalker Ranch. In the episode this week they hired a professor to do a balloon launch with some RF sensors. In this episode they also showed the APRS.FI webpage and I was able to read his callsign from an APRS tracker, KM4MRH.

The professor used an APRS tracking device. On the right side of the page link below you can click on Other SSID’s to see other balloon launches he has done. Normally when there is a balloon launch you can see the data from it going up and down. This page shows the Skinwalker balloon launch data transposed over a map. https://aprs.fi/#!call=a%2FKM4MRH-3&timerange=3600&tail=3600

Sadly they are using these for measuring RF fields rather than these.

In a Crisis, Radio Should Be Bigger Than Ever — So Why Isn’t It? (Rolling Stone)

Terrestrial music stations have a major cultural opportunity right now, but employees say a muddied strategy is standing in the way

Radio personality Kevin Ryder was “baffled” by KROQ’s “cold, heartless attitude” when he and his morning-show team were fired at the end of March. The station has long been an alternative/rock staple in Los Angeles, the second-largest market in the country, and Ryder had been on the air for more than 30 years.

“The new people in charge now weren’t here for the building of the world-famous KROQ,” Ryder, one-half of the popular Kevin & Bean Show, said on air when the station let him go, live one final time. “I don’t think it means anything to them. It’s a numbers business, and there’s no family aspect to it anymore. It’s only numbers, but this place was built without numbers. It was musicians, artists, and the special relationship between music, the station, and our fans.”

AM/FM radio provides localized, round-the-clock information and entertainment via friendly neighborhood voices — so in theory, it’s the perfect platform in a global crisis that forces hundreds of millions of people to stay home. But Ryder is one of many in the radio community — including on-air hosts, music directors, program directors — who have been shocked by sudden job losses in recent weeks as COVID-19 has spread across the U.S., and news out of the industry has been one bad thing after another. Why is terrestrial radio missing the opportunity here — and how should it be fighting to get back on top?[]

Frequency coordination news and IRDR updates

Many thanks to SWLing Post contributor, Alan Hughes, who shares this article by WRMI’s Jeff White in Radio World magazine. Besides covering updates in the A19 broadcast season, and Radio Exterior de España’s increased broadcasts, Jeff notes frequencies and updates for the International Radio for Disaster Relief initiative.

For more information about the IRDR, check out the information below taken from this page on the HFCC website:

International Radio for Disaster Relief (IRDR)
Humanitarian Aspects of HFCC Activities

From its infancy since 1920s shortwave radio has been associated with its potential of being a communication tool in emergencies. This use of shortwave radio is still very much present among amateur radio enthusiasts for example, who discovered its long distance properties early in the twentieth century. Amateur radio provides a means of communication on shortwaves and other frequencies “when all else fails”. This role of amateur radio is well recognised, valued and appreciated both by the public and by the world institutions managing and regulating the use of the radio spectrum.

In contrast the huge technical potential of international shortwave broadcasting that operates transmitter facilities tens, or hundred times, more powerful than those of amateur radio, remains almost unused in emergencies. At the moment when local and even regional communication and information networks are needed most, they are destroyed or overloaded and the population suffers from an information blackout. Shortwave radio is capable of remaining the only source of information.

Although the life-saving role of radio broadcasting is widely recognised by the public, and confirmed by surveys conducted after the recent disasters – and even acknowledged by world leaders – no concrete projects have been ever designed and no regulatory framework has been developed.

That is why the HFCC – International Broadcasting Delivery in co-operation with the Arab States and Asia-Pacific broadcasting unions are working on an International Radio for Disaster Relief (IRDR) project that is based on the system of online co-ordination of frequencies managed by the HFCC in accordance with International Radio Regulations.

The HFCC is aware of the humanitarian aspects of international broadcasting. It pointed out in 2012 – as the UNESCO partner for the preparation of the World Radio Day – that terrestrial shortwave radio in particular is still considered as a powerful communication and information tool during emergency situations. Read more >>

Receivers are inexpensive and require no access fees. Shortwave radio is important for people living in remote and isolated regions of the world. It reaches across the digital divide to the most disadvantaged and marginalised societies. This is also in keeping with the Declaration and Action Plan of the World Summit on the Information Society.

The annual edition of the World Disasters Report of the International Red Cross and Red Crescent Societies (IFRC) issued in October 2013 stressed again that with only 6 percent of people in low-income countries using the internet in 2011 the digital divide is still stark, and access to low cost media technology is really the key.

The HFCC is a strong advocate for incorporating terrestrial broadcasting permanently on the disaster risk reduction agendas of the ITU and other UN agencies and institutions. It submitted two documents for the ITU-R Working Party 6A November 2013 meeting:

HFCC – The Importance of Terrestrial radio in International Broadcasting
HFCC – The International Radio for Disaster Relief Project

Both documents are annexes in Section 8 of the ITU-R Study Group 6 Report BT.2266 “Broadcasting for public warning, disaster mitigation and relief”. The report can be downloaded via this link.

A workshop was held during the November 2013 meeting addressing these issues. The web site of the Emergency Broadcasting Workshop can be accessed here. The web site also contains copies of all the presentations that were made at the workshop, and a Video interview with Christoph Dosch, Chairman of ITU-R Study Group 6 (Broadcasting service)

The HFCC has applied for membership in the CDAC (Communicating with Disaster Affected Communities) Network in keeping with the conclusion of the debate on emergency communication during the Bratislava B13 Conference. Read more >>

The HFCC is staying in touch with the Information and Communication Sector of the UNESCO agency on the preparation of the World Radio Days that are celebrated each year on February 13th.

Humanitarian aspects of terrestrial broadcasting were also on the agenda of the Global Kuala Lumpur conference in January 2014. Read Opening Remarks.

The “Tecsun Radios Australia Q-3061” DRM Shortwave Radio

Many thanks to SWLing Post contributor, Alan Hughes, who notes that Tecsun Radios Australia have announced a new DRM stand-alone receiver: the Q-3061.

When I first received Alan’s tip, I was surprised that I had not been been given some advance notice or even a hint about Tecsun developing and producing a DRM radio. Then I saw the Q-3061 product image and it looked to be a spitting image of the Gospell GR-216 DRM radio. A quick look at the radio’s back panel and the connection with the GR-216 was confirmed.

Reading through the product description, it appears they worked with Gospell to badge this for Tecsun Radios Australia’s primary markets:

“The Tecsun Radios Australia Q-3061 DRM Shortwave Radio is for experienced shortwave users. There a limited number of DRM signals available in our region although the total number of DRM broadcasts are increasing. This radio is squarely aimed at radio enthusiasts and DXers, most signals require an external antenna, experience, and patience. We recommend our Tecsun Radios Australia Q-3061 DRM Shortwave Radio be used in conjunction with our Tecsun Shortwave and AM Outdoor Antenna for the best results (this is the setup we have in our Brookvale NSW office).

The Tecsun Radios Australia Q-3061 DRM Shortwave Radio is the culmination of several years work. Tecsun Radios Australia has worked in close co-operation with the manufacturer providing testing results from locations across the Pacific, including Samoa, Vanuatu, Solomon Islands, Fiji, and New Zealand. Reception of DRM signals in Australia requires many factors to be optimised, because we are outside the traditional coverage area of most broadcasters. Nevertheless, with an optimised antenna, correct selection of DRM broadcaster, schedule and good propagation conditions DRM signals can be received. New DRM broadcasters are appearing every month.”

After the product description they also include this disclaimer:

Note: This DRM radio has no association with Tecsun of China and is an exclusive initiative and product of Tecsun Radios Australia

The price is $500 AU or approximately $357 US.

To recap, this isn’t a new Tecsun DRM radio, rather it’s a rebadged GR-216 for the retailer/distributor Tecsun Radios Australia.
