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.

Many thanks to SWLing Post contributor, David Iurescia, who shares the following news item via SwissInfo.ch:

Swiss Broadcasting Corporation pulls plug on FM radio (SwissInfo.ch)

The Swiss Broadcasting Corporation (SBC) switched off outdated analogue FM transmitters at 11:59pm on New Year’s Eve.

Connections to around 850 ultra-shortwave transmitters throughout Switzerland have come to an end.

Anyone wishing to continue listening to the radio stations SRF1, SRF2 Kultur und SRF3 in the new year, for example, will have to switch to the digital radio technology DAB+ or Internet radio. All other SBC programmes were previously only available via the Internet or DAB+.

SBC, SWI swissinfo.ch’s parent company, now only needs around 260 antennas for DAB+ broadcasting.

Around two dozen private radio stations in Switzerland will continue to broadcast via FM and will not discontinue the service until the end of 2026 at the latest. [Continue reading…]

Radio Waves:  Stories Making Waves in the World of Radio

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 Stefano Rampazzo, David Iurescia, and Paul for the following tips:

SWLtools App for the Belka receiver

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

I am a proud owner of a Belka receiver and I really love it.

The Belka is small, it is simple, it works very well outdoors with its short antenna that outperforms my desktop receivers with long wire antennas

Its size allows you to put it in your pocket, take it on a trip, on vacation, anywhere.
I have often sat in my garden at night with my Belka, away from the electrical noise of the house, and made some really good listening. In these situations I realized that I needed to record my dx. I thought about buying a mini-recorder, but since I always have my iPhone with me I decided to develop an app to record the audio of my Belka. After some time I am happy to let you know that my new app SWLtools is available on the Apple AppStore.

SWLtools allows you to record, play back and share your best listening. Also, since Belka also has an additional output where the IQ signal is present, I also added a function to the app to display the spectrum and spectrogram (waterfall).

As you know, modern smartphones do not have analog inputs and outputs, so to use SWLtools it is mandatory to have a USB audio device.

I bought a cheap USB dongle with a line input and output. Its sampling rate is 44.1 kHz, it is very low, but it is enough for minimal viewing.

SWLtools is available for free on the Apple AppStore (and it is also ad-free).

DAB+ receivers to be woken up in crisis situations (World DAB)

From next year, new DAB+ receivers will have better audio and text alerts in crisis situations. The current standard for alerts is called AAS (Alarm Annoucement Switching) and was introduced in 2020. In a crisis situation, receivers will switch to the station responsible for crisis information and the screen will also provide short text information. DAB+ also allows for the creation of temporary radio channels in crisis situations, which was used during the Brisbane floods in 2011. Over the past two years, the new Automatic Safety Alert (ASA) standard has been developed by WorldDAB and Digitalradio Deutschland in co-operation with chip manufacturer Frontier Smart Technologies and electronics manufacturers such as Technisat and JVC Kenwood. Among other things, receivers with ASA can be switched on automatically in emergency situations.

Rti to launch Arabic podcasts on September 30 (RTI)

On Wednesday, Radio Taiwan International announced that it will launch its new Arabic podcasts on International Podcast Day on September 30 at the 2024 Rti Arabic Day Forum.

Rti’s president Chang Jui-Chang (???), speaking at the event titled “Rti Arabic Day: Taiwan Steps into the Arab World – Taiwan-Arab Cultural Exchange Forum,” remarked on the historical context of Rti’s Arabic programming, which began in 1950 but was halted in 2005 due to budget constraints. It was only on Eid al-Fitr in May 2021 that Rti re-initiated its outreach to Arab audiences through social media, achieving significant success over the past three years.

The forum featured several experts, including Representative Mr. Adel Fahad Althaidi of the Saudi Arabian Trade Office in Taipei, Scholar Ouyang Wen-chin (????), Assistant Professor Tsung Pei-chen (???), Lecturer Fu Yi-hsuang (???) from National Chengchi University’s Arabic Department, and former Associate Professor Hsu Cheng-hsiang (???). Fu highlighted that Taiwanese cinema serves as a window for the Arab world to understand Taiwan, noting the frequent cultural festivals, such as film, music, and dance festivals hosted abroad by the Ministry of Foreign Affairs to promote cultural exchange.

Rearchiving 2 million hours of digital radio, a comprehensive process (National Library – Norway)

The National Library is in the process of a major overhaul of its 2007 bit-repository, replacing it with a contemporary digital preservation system. This new solution is based on an in-house developed system called DPS (Digital Preservation Services), which uses IBM-HPSS as the underlying bit repository for data storage. This transition, which is expected to span over a couple of years, is necessary to ensure the long-term preservation and accessibility of the National Library’s digital collection.

Transition to a New Preservation Solution
In 2023, all new data archiving was transferred to the new DPS preservation solution. At this time, the old bit repository contained over 14 Petabytes of digitized and legally deposited historical material, which needs to be re-archived into DPS. A key part of this process involves analyzing and repackaging the historical data to meet the new DPS requirements.

Historical Legally Deposited Radio
Among the materials to be re-archived are 2.2 million hours of digital radio, equivalent to 2.5 million files and a total of 1 Petabyte of data. This includes both born-digital and digitized radio programs from the period 1993-2022.

In 1993, there were four radio channels delivering 16,500 hours of radio. By 2022, the number of radio channels had increased to 30, collectively delivering 150,000 hours of radio. With the phasing out of the old bit repository, it became necessary to move this data to the new preservation solution.

DSM to DPS: A Thorough Process
DSM (Digital Longterm Storage) has been the National Library’s internal management system for legally deposited radio for the past 20 years. The data has been stored in an Oracle HSM bit-repository in three instances (disk, tape, tape), and the radio material was fetched daily from various broadcasters. Some radio broadcasts were stored as mp3 and wav files, with accompanying checksum files. Other broadcasts were only stored as mp3. [Continue reading on the National Library blog…]

DAB+ digital audio/FM receiver and Bluetooth Audio Player with 2.4 inch LCD Display 

by Mangosman

Digital Audio Broadcasting with improved audio compression and error correction is called DAB+. I have had this radio for a few years.

Retail in Australia DAB+/FM radios are generally double the price and more. There has only been one model of DAB+/FM/AM radios which is now no longer trading.

This is a size comparison, the sound is very clear and is surprisingly good on music as well, despite having such a small speaker. Even at maximum volume there is no audible noise or distortion. The stereo program HE AAC compressed and FM and Bluetooth and is available on cabled headphones. Such a small speaker cannot produce much in the way of bass, but it is present on headphones.  Since DAB+ is a pure digital system, there is, full stereo, no noise as the radiated signal deteriorates, until the receiver mutes when error correction fails. The radio has a 400 mm long telescopic antenna.

On FM this receiver will decode Radio Data System data, I have had more sensitive FM reception.

This is the most sensitive DAB+ receiver I have owned. I am also currently also using two BUSH clock radios. I also have used older headphone radios, but push buttons and headphone sockets haven’t been very reliable.

This screen shows a full  colour album cover which can fill the screen and title. Smooth FM is the broadcaster’s name because it is simulcast in some other cities on FM and DAB+. The indicators on this screen are level of battery change, muting, stereo indicator, when decoded and the signal strength. Continue reading →

“In Lviv, journalist Vitaly Portnikov, who hosts programs on Espresso and Radio Svoboda, found a eavesdropping device at home. It is a voice recorder with the ability to record for a long time. The police were called. They arrived quickly. The SBU was called. They are not going. As a member of the Verkhovna Rada, I ask the SBU to come immediately and disrupt case. We don’t know who installed this device and for what purpose: our services, foreign services or criminality,” the politician said.

Vitaly Portnikov commented on the incident for “Espresso”:

“Today, while cleaning the apartment I lived in at the end of February, when the war started, I found a recording device under the bed. The device had an inventory number. I informed the law enforcement authorities about my discovery so that they could investigate this incident.”

The journalist added that he hoped for a high-quality investigation and clarification of all the circumstances of the case:

“After my statement, the investigators of the SBU of the Lviv region conducted an inspection of the premises and seized a device that is a device for listening and recording information. I hope that the relevant structures will conduct an examination and find out by whom and why this device was placed in my apartment.”

RNZ welcomes Pacific infrastructure investment

Released at 3:19 pm on 19 May 2022

RNZ Chief Executive and Editor-in-Chief Paul Thompson has welcomed the budget investment in RNZ Pacific shortwave transmitters.

In Budget 2022 the Government announced $4.4 million dollars capital funding for a new transmitter for RNZ Pacific.

RNZ Pacific broadcasts into the wider Pacific on shortwave 24 hours a day, collaborating with 22 broadcasting partners across the region. Its current primary transmitter is nearing end of life, and its other transmitter has in effect already been retired.

“The value of the RNZ Pacific service can’t be underestimated. Our voice reaches all parts of the Pacific, at times with critical information such as cyclone warnings. During the Tonga eruption, when the undersea cable was cut, RNZ Pacific short wave was a lifeline source of information,” said Thompson.

This investment secures a productive future for our unique voice. The attraction of the shortwave service is its robustness, and the ability to have the signal travel great distances, and achieve good audiences,” he said.

RNZ Pacific broadcasts enhance the Government’s Pacific strategy as we share our history, culture, politics and demographics. The strategy is underpinned by the building of deeper, more mature partnerships with Pacific Island countries, and by supporting their independence and sustainable social and economic resilience.

Since the ABC ceased its shortwave broadcasting the only other shortwave broadcaster in the region is Radio China. Thompson says RNZ can now start work on its infrastructure development with a new transmitter likely to take approximately 12 months to get in place depending subject to further project planning.

Public Service Media Continue To Mobilize Wide Range Of Support For Ukrainian Refugees (EBU)

More than 14 million people have fled their homes since Russia’s invasion of Ukraine and the war shows no sign of ending. For World Refugee Day on 20 June, we are highlighting some of the issues faced by displaced Ukrainian people – and reaffirming that the support from the EBU and its Members will continue.

That support has manifested across a range of projects:

Air strikes on the TV towers in Kyiv and Rivne underlined the vulnerability of broadcast communications in a war zone. Together with our Members, we have coordinated the supply and delivery of critical equipment such as IP connectivity solutions, satellite phones, AM transmitters, and studio support to enable the uninterrupted transmission of vital news and information.

In these circumstances, being able to rely on accurate news sources is key. Many EBU Members have launched dedicated news services specifically for refugees in their own language, so that they can tap into vital updates from home, wherever in the world they are. Rai News in Italy has a daily news bulletin in Ukrainian; RTBF UKRAINE is a new web-based radio station for Ukrainian refugees in Belgium, with 100% of its content in Ukrainian; and Yle in Finland has a Ukrainian-language news service for providing the latest news bulletins in Ukrainian. Many public media outlets are also re-transmitting content directly from Ukrainian public broadcaster, UA/PBC for Ukrainian refugees.

Providing practical information to help people navigate the uncertainties of settling into new homes has also been a priority and has seen the launch of many dedicated programming and channels: GPB has a hotline for Ukrainians in Georgia; Czech Radio and Radio Prague have launched a podcast, ‘News for Ukrainians in Czech Republic’, that offers practical information for incomers. While ARD in Germany presents How To Deutschland Insta; Swedish Radio’s Ukrainian service for new arrivals includes practical advice on how to access medical care or education facilities for kids and RTP’s online service helps with learning a new language.

For children, displacement through war is particularly traumatic. TVP in Poland has developed a site for kids from Ukraine which, as well as showing selected content in Ukrainian, also presents lessons in learning Polish; ARD and ZDF in Germany have included content in Ukrainian for children, including German-language learning programmes, and Czech Radio has recorded fairytales in Ukrainian.

Noel Curran, Director General, EBU, said “Few of us can understand the trauma of being forced to leave our homes, not knowing when or if we will return. I’m proud to belong to a community that has mobilized a wide range of practical support so quickly while ensuring trusted news and information continues to reach those who need it, wherever in the world they are. World Refugee Day is a moment to reflect on a situation that continues to need targeted support. And to reaffirm our commitment to giving it for as long as it takes.”

Rising Energy Costs Could Spur Digital Migration (Radio World)

Projected cost reductions cited as reason for Germany to accelerate the migration to DAB+

As energy costs rise, Deutschlandradio Director Sefan Raue sees a further reason to hasten an FM switch-off for Germany.

“We will not be able to afford two terrestrial distribution channels in the long run. The signs are clearer than two or three years ago,” Raue told German press agency dpa, according to Hadelsblatt. “FM is an energy guzzler.”

A public broadcaster, Deutschlandradio is based in Cologne and Berlin and operates several national channels on DAB+ and FM. The channel been steadily replacing its remaining FM transmitters with DAB+; six of its short-range analog transmitters are going dark at the end of June 2022. The broadcaster expects to have at total of 161 locations broadcasting its DAB+ channels nationwide by year-end, reaching some 90% of the German populace. [Continue reading at Radio World…]
