Digital Radio Mondiale Releases the DRM Consumer Radio Receiver Functionality Recommendation (DRM Consortium)

The DRM Consortium (www.drm.org) releases today its DRM Consumer Radio Receiver Functionality Recommendation (rxspec.drm.org). The document describes and defines the core functional parameters of consumer radio receivers capable of receiving DRM radio broadcasts. As DRM is being increasingly rolled out, adopted and demonstrated globally such a document is necessary to offer a guide to receiver manufacturers, but also broadcasters and regulators, so that consumers get a common and consistent DRM digital radio experience.

[…]The DRM Receiver Functionality Recommendation applies to all types of consumer-targeting DRM radio receivers, with detailed application-specific requirements for automotive receivers, personal mobile devices (such as mobile, feature, and smart phones or tablets incorporating built-in radio receiver functionality for terrestrial broadcast radio), and general-purpose receivers (all types of stand-alone receivers, including home and desktop radios).

The Consumer Receiver Recommendation builds upon the more technical DRM MRR – Minimum Receiver Requirements Specification (mrr.drm.org), which must be implemented and followed by any DRM receiver.

The new Consumer Receiver Recommendation covers DRM digital radio in all broadcasting bands: in the LW, MW, SW and VHF bands (Band I, II and III) and analogue AM and analogue FM radio. [Continue reading…]

WorldDAB Summit: Ensuring Radio Stays Prominent in the Car (Radio World)

Summary: At the WorldDAB Summit 2024 in Zagreb, industry leaders emphasized the importance of keeping radio front and center in the evolving connected car landscape. Gregor Pötzsch of Volkswagen Group’s CARIAD stressed the need for easy findability and engaging multimedia content, while Tomas Granryd of the EBU Connected Car Playbook highlighted the challenges posed by hidden FM/DAB buttons, voice activation inconsistencies, and increasing competition from global digital platforms. With 70% of in-car audio still coming from radio, broadcasters have the leverage to shape dashboard integration, ensuring seamless hybrid reception and intuitive voice control.

Many thanks to SWLing Post contributors Dennis Dura, and Alan for the following tips:

Radio Apocalypse: HFGCS, The Backup Plan For Doomsday (Hackaday)

To the extent that you have an opinion on something like high-frequency (HF) radio, you probably associate it with amateur radio operators, hunched over their gear late at night as they try to make contact with a random stranger across the globe to talk about the fact that they’re both doing the same thing at the same time. In a world where you can reach out to almost anyone else in an instant using flashy apps on the Internet, HF radio’s reputation as somewhat old and fuddy is well-earned.

Like the general population, modern militaries have largely switched to digital networks and satellite links, using them to coordinate and command their strategic forces on a global level. But while military nets are designed to be resilient to attack, there’s only so much damage they can absorb before becoming degraded to the point of uselessness. A backup plan makes good military sense, and the properties of radio waves between 3 MHz and 30 MHz, especially the ability to bounce off the ionosphere, make HF radio a perfect fit.

SDR: The Next Level of Shortwave Radio Listening (Radio World)

Where have these things been all my life?

There is a new breed of RF receivers known as software-defined radios, and they are revolutionizing the way in which people listen to shortwave (SW) radio, or indeed any form of radio broadcast.

SDRs combine plug-in radio receiver dongles/boxes with personal computers, with the computer serving as the user interface. What makes this interface so useful is that the listener’s screen displays a wide swath of the bandwidth being tuned to, with each station’s signal shown as a visual vertical line that moves and grows/shrinks with its signal strength.

In other words, the listener can literally see what is happening across the band in real time, rather than having to turn the dial or push the Up/Down scanning buttons on a conventional shortwave radio, checking one station at a time. [Continue reading…]

Many thanks to SWLing Post contributor, David Iurescia, who shares the following news release via the DRM Consortium:

DRM RNZ Shortwave Transmitter For Pacific Inaugurated

On August 1st the New Zealand Deputy Prime Minister and Foreign Minister came to RNZ House in Wellington to mark the start of the use of the new analogue and DRM transmitter, replacing a 34-year-old transmitter at the Rangitaiki broadcast site.

In a $4.4-million-dollar project, the public broadcaster RNZ has installed a new Swiss-made Ampegon shortwave transmitter.

Chief Executive and Editor-in-Chief Paul Thompson said it’s a significant infrastructure upgrade and secures the future of the RNZ shortwave service into the wider Pacific.

RNZ Pacific broadcasts into the wider Pacific on shortwave 24 hours a day, broadcasting in English and Pacific languages, in collaboration with 22 broadcasting partners across the region.

“The attraction of the shortwave service is that it delivers our unique voice and content to all parts of the Pacific via a signal which can carry over great distances, and achieve good audiences,” said Thompson.

“RNZ Pacific is an essential source of information, especially so during the cyclone season or during a crisis such as the Tonga eruptions,” he said.

RNZ’s Transmission Engineer Specialist Steve White said the project to replace the 34-year-old transmitter at the Rangitaiki broadcast site near Taupo had gone smoothly – being on budget and achieved without disruption to service. “We have appreciated the close working relationship with Ampegon for the new transmitter installation,” he said.

This Shortwave Station’s Transmitter Site Sits Pretty in the Tropics (Radio World)

KTWR’s home is on Guam, which makes for some interesting broadcasting

If you’re an avid Radio World reader, you know that we love to highlight unique radio facilities, whether they be local or abroad. If you happen to love that sort of content, you’re in luck!

Broadcasting since 1954, Trans World Radio, or TWR, is a Christian radio distributor that collaborates with U.S.-based radio stations to spread the gospel via local FMs, mediumwave or high-powered AMs and shortwave transmitters.

According to its website, TWR’s programming is broadcast in 200-plus languages on air, online and on the ground in 190 countries. It is celebrating its 70th anniversary this month.

With such an extensive résumé, TWR was bound to have at least a few unique transmitter sites. One such site that we’ll share with you here can be found “Where America’s Day Begins,” floating just above the equator in the western Pacific Ocean.

In Micronesia, TWR’s shortwave member station on Guam, KTWR, serves listeners across most of Asia, spanning Siberia to India to Indonesia. [Continue reading…]

Video: DRM at BES (DRM Consortium)

The recently concluded BES Expo 2024 has occasioned the presentation of several new DRM achievements under one single (stall) roof.

For those who could not join the DRM Consortium members in India, here is a tour of the best under the guidance of Alexander Zink, vice-chairman of the DRM Consortium:

Radio Poland marks 88 years on air (Polskie Radio)

Radio Poland is celebrating its 88th anniversary on the air.

The station, launched on March 1, 1936, is part of Poland’s public radio network.

It broadcasts programmes on developments at home and abroad, Polish foreign policy, the economy, business and foreign investment.

Radio Poland, also known as Polish Radio’s External Service (Polskie Radio dla Zagranicy), aims to provide objective and impartial information about Poland and the country’s stance on international affairs.

It reports on developments in Polish society, its daily life as well as scientific and cultural achievements.

The thenews.pl website, part of Radio Poland, is a leading English-language resource for Polish news.

Updated regularly all day, every day, the website covers domestic and foreign affairs, economy and business, culture, sports and human interest stories.

Polish Radio launched shortwave broadcasts in English and Polish in 1936. They were discontinued with the outbreak of World War II in 1939.

After the end of the war in 1945, the shortwave channel Warszawa III resumed external broadcasts.

In 1990, Polish Radio started broadcasting in Ukrainian, Belarusian, Lithuanian, Czech and Slovak.

Then in 1994 the External Service began daily broadcasts in several languages via the World Radio Network.

In 2007, Polish Radio’s External Service launched its news website, now available at www.polskieradio.pl.

Today, Radio Poland broadcasts in Polish and five foreign languages: English, German, Russian, Ukrainian and Belarusian. [Continue reading…]

Now Is the Time to Save AM in Cars Using Digital (Radio World)

“DRM eliminates unstable and degraded audio, saves spectrum and, more importantly, a lot of energy costs”

The author is chairman of the DRM Consortium. Her commentaries appear regularly at radioworld.com.

Much ink has been used recently on the topic of carmakers dropping AM reception capability in cars, especially in EVs. Hence the “for and against” discussions in the U.S., at least, about the “AM for Every Vehicle Act.”

Shortwave reception, with is large coverage possibilities, has often been criticized for its audio quality which can be noisy and subject to annoying levels of variations. In cars, there are other drawbacks like less than optimum antennas, which are mostly tuned for vertical polarization while shortwave is horizontally polarized.

It is undeniable that analog AM Shortwave reception in cars can be quite unreliable, also due to lower average-SNR over time. But all these negative points are not always present. In some places (take Nigeria and the BBC broadcasts) the shortwave transmissions are great, in a quality that is not much different from that of a FM broadcast. [Continue reading…]

Bong! Big Ben broadcasts to return to Radio 4’s regular schedule (The Guardian)

Westminster’s famous bell will be heard live from next week after years of only occasional appearances

It is one of the most recognisable sounds in the UK, and one that hasn’t been heard on BBC Radio 4 since New Year’s Eve last year, but from next week the famous bongs of Big Ben will be heard once again on the station.

The most famous bell in the UK will be heard live once again on Monday 6 November, just before the 6pm news bulletin and again before midnight. Listeners will be able to hear the chimes again before Radio 4’s Westminster Hour political discussion programme at 10pm on Sundays.

And after years of only occasional appearances, the chimes will form part of Radio 4’s regular schedule where they will be heard live twice daily and three times on Sundays after new microphones and a live set-up were installed.

To mark the nation’s two-minute silence this Remembrance Sunday, Big Ben will also be heard live on 11 November at 11am, and the bongs will air at 3pm on Christmas Day, before the king’s speech is broadcast on Radio 4. [Continue reading…]
