Ampegon Puts Focus on Shortwave Transmitters (Radio World)

Ampegon Power Electronics highlights progress on the company’s third-generation solid-state shortwave transmitters, which it says will offer “significant advances in efficiency.”

The company says this work will pave the way toward higher-power broadcast outputs and meet current expectations of a shortwave equivalent to medium-wave and FM transmitters. “Combined, these two developments will bring FM-quality broadcasts with all the benefits of shortwave,” said Simon Keens, Ampegon sales and business development manager.

Ampegon has also developed a retrofit upgrade to current UCS generation control systems for previous generation 100 kW, 250 kW, 300 kW and 500 kW transmitter systems.[…]

Listening together, listening alone: A music professor sounds off on his shifting industries (CBC)

Brian Fauteux reflects on the way COVID-19 is affecting his two passions: music and teaching

A lot of great songs effectively reflect the feelings that accompany isolation. The experience of being alone, however, is often constructed in opposition to a longing for togetherness. Heart’s “Alone” (1987) — maybe the greatest power ballad ever recorded — confidently asserts, “‘Til now I always got by on my own.” But this is no longer the case when the song’s protagonist meets and develops undeniable feelings for another: “And now it chills me to the bone.” In another iconic 80s anthem, “Dancing in the Dark,” Springsteen grows tired and bored with himself against the desperate urge to join up with “something happening somewhere.” The act of dancing in the dark can be fun, sure, but it’s much more fun with others. Inspiration in isolation is insubstantial.

I’m an Assistant Professor of Popular Music and Media Studies, and I teach and write about the role of music in society. I’m interested in how our listening practices shape, and are shaped by, issues of sustainability in the music industries — that is, how artists make (or struggle to make) a living in this day and age.[…]

EU directive on digital radio in cars (Times of Malta)

Directive (EU) 2018/1972 of the European Parliament and of the Council of December 11, 2018, establishing the European Electronic Communications Code (‘EECC’) entered into force on December 20, 2018. Member states have two years to incorporate it into national law, except where specifically mentioned.

Radio is an important medium through which citizens access a diverse range of information news and entertainment services. The EECC leverages on the ever-increasing connectivity of new generation cars as well as on the digital platforms of radio broadcasters to guarantee a more robust radio experience to all drivers, ensuring good coverage, a wider choice of radio stations and more effective access to information at all times. The EECC ensures that car drivers have access to the benefits of digital terrestrial radio wherever in the EU they have bought their new car.

On April 21, the minister responsible for communications, in consultation with the Malta Communications Authority, published Legal Notice 151 of 2020 amending the Electronic Communications Network and Services (General) Regulations, implementing the provision of the EECC dealing with the interoperability of car radio devices. In line with the regulation, any car radio receiver integrated in a new vehicle of category M which is made available on the market for sale or rent in Malta from December 21, 2020, shall comprise a receiver capable of receiving and reproducing at least radio services provided by digital terrestrial radio broadcasting of type DAB+. Radio programmes in Malta are broadcast terrestrially on DAB+.

The car radio requirement only applies to new cars.[…]

EU vehicle digital radio legislation

9 Replies

Many thanks to SWLing Post contributor, Mangosman, who shares the following:

The European Union as asking its member states to legislate the following, which Germany has just done today.

EU Vehicle Directive

This directive requires all new car radios sold in the European Union to be capable of receiving digital terrestrial radio, in addition to any FM or AM functionality which manufacturers may want to include. The code also grants EU member states the power to introduce rules requiring consumer radios to include digital capability.

Following its adoption by the European Council, the directive was published in the Official Journal of the European Union (OJEU) and came into force on Dec 20 last year. For the automotive industry, the key section of the European Electronic Communications Code is Article 113, XI:

“Any car radio receiver integrated in a new vehicle of category M which is made available on the market for sale or rent in the Union from … [two years after the date of entry into force of this Directive] shall comprise a receiver capable of receiving and reproducing at least radio services provided via digital terrestrial radio broadcasting. Receivers which are in accordance with harmonized standards the references of which have been published in the Official Journal of the European Union or with parts thereof shall be considered to comply with that requirement covered by those standards or parts thereof.”

The policy commences 21st December 2020 and applies to any vehicle with 4 or more wheels. It does not apply to amateur radio equipment. The radio must be able to display the broadcasters’ name.

Note the way the type of receiver is phrased is digital terrestrial radio, it does not specify what type. It obviously applies to DAB+ because there are many DAB+ transmitters in Europe, but could also apply to DRM. With the advent of Software defined receivers, it is easy to have both standards. This would then open they way for high frequency (short wave) DRM in most vehicle radios. Remember that there are now 1.5 million factory installed DRM car radios in India which has been achieved in 18 months.

This decision will open the way for all new radios to include DAB+/DRM in all markets except the USA/Mexico.

Thank you for sharing this!

“Pirate DAB multiplexes take to the air in Dublin and Cork”

3 Replies

(Source: Radio Today Ireland via Mike Terry)

Pirate radio stations are appearing on unlicenced DAB digital multiplexes in Dublin and Cork, and more are planned for other cities in Ireland.

The “FreeDAB” platform, now carrying around ten stations, was born out of frustration over the procedures in place to broadcast legally on DAB in Ireland.

During the recent 12-month legal DAB multiplex trial operated by ‘éirdab’ in Cork, a radio station wanting to broadcast via this method would need to pay upfront for a five-year Section 71 licence (a list price of €14,000 (plus VAT)) and wait up to five months for the application to be processed.

But waiting five months for a licence and paying five years up-front to be on a 12-month trial are just two of the issues holding back DAB in Ireland.

The technology required to broadcast a multiplex is now easier to acquire and is mostly controlled by software whilst costs to broadcast illegally via the multiplexes also appear to be very low.[…]

Small-scale DAB could lead to hundreds of new UK radio stations

2 Replies

(Source: Southgate ARC)

Hundreds of new local digital radio stations could start broadcasting in the UK from next year, under proposals outlined by Ofcom

Ofcom say:

With over 40% of the UK’s radio listening now taking place on the Digital Audio Broadcasting (DAB) platform, today’s proposals mark a major step towards expanding local DAB coverage, giving listeners an even wider choice of new digital radio stations.

Small-scale DAB is cutting-edge technology, pioneered in the UK by an Ofcom engineer. It provides local commercial, community and specialist music stations with a low-cost route to hitting the digital airwaves.

The consultation sets out:

• our proposed spectrum and licensing process;
• our approach to developing a coverage area plan; and
• how we intend to advertise licences and assess applications.

We would like to hear from interested parties by Friday 4 October and intend to start advertising licences early in 2020.

Radio France’s digital ambitions and AM radio in Australia

3 Replies

Many thanks to SWLing Post contributor, Jason Whiteley, who writes:

Hi Thomas,

[T]here is a really interesting interview with Radio France here around their DAB+ expansion and the possible shut down of FM in France later [click here to read].

I used Google Translate to bring it to English.

[Y]ou might also choose to link to this article about AM radio being dead in Europe (written in 2015):

https://www.radioinfo.com.au/news/am-radio-dead-europe

The article is bang on though – AM radio is still very strong and thriving in Australia & the USA. Here in Australia at least, it’s DAB that has a minimal audience compared to traditional AM broadcast.

I just found both of these articles very interesting reading and thought you might like to put them up.

Have a great day,
Jason

Thank you very much for sharing these articles, Jason! Earlier today, we posted a note about digital AM here in the States (AM HD). There is a movement to increase this offering, but for true market penetration it would require car radios that can receive AM HD. Many a DXer dislikes AM HD because the digital signals are (unlike DAB+) inserted between analog signals. These band crowding sometimes causes interference to adjacent analog stations and certainly affects mediumwave DXing.

Eton/Grundig Satellit: Michael seeks advice on enabling DAB reception

7 Replies

Many thanks to SWLing Post contributor, Michael Meyer, who writes:

Hi Thomas.

I have a question regarding the Eton Grundig Satellit’s DAB function – or rather: It’s missing DAB function.

The Eton Grundig Satellit was reviewed in WRTH 2016 by John Nelson, demonstrating its capability of receiving DAB (Digital Audio Broadcast in Europe – some politicians want to shut down FM-band and replace it with DAB only). Since I live in Denmark, where DAB+ is widely implemented as a supplement of FM broadcasts, I do find this function unique, since it must be the only shortwave radio with DAB on the marked.

The SWLing Post have had some reviews as well as a link to Amazon.com, which tempted me to buy the “Executive Edition” at an attractive price. It arrived in early December 2018, and I am happy with most of the features of this radio. Good audio, sensitive and a nice size for a portable. I do agree with other reviewers regarding the mediocre sync-function, but I got truly surprised regarding the selectivity on shortwave, which on my model is poor! Strong broadcasters can easily be tuned 5 kHz away from their “true” frequency – even when putting bandwith to 3 kHz, there is not much difference in audio on VOA on 15580 kHz tuning to 15575 nor 15585 kHz. But when tuned, reception is stable and audio is good. Another very weird issue is the “double-click” feature, where first press on any button activates the light only – and the user has to press again to actually activate button function!

But now to the main reason for me writing this: How does the user activate DAB? I wrote to WRTH to get their opinion on this – I paste in my correspondence with them (I have got their permission to do so in writing you):

Dear Mr Meyer,

The version we were sent for review had a DAB+ function. Several readers
have since written to say they could not find the function despite the fact
that it is shown in the display. We have raised this matter with Eton but
have not received an answer. We may be wrong but our impression is that the
company did not apply for CE approval and as a result never implemented the
DAB function in the production models. The FCC approved versions of the
receiver of course would not require DAB.

It might be worth putting the question on the DX chat groups and see if
someone has found a solution.

Kind regards,

WRTHdx
