TECHNOLOGY: SWITZERLAND THE FIRST RADIO IN EUROPE TO USE ARTIFICIAL INTELLIGENCE

Couleur 3 is the first European radio station to go on the air for half a day with programs created by artificial intelligence: lyrics, music, and speaker voices. Only the news remained handled by the traditional newsroom. Here’s how it went

The Swiss are not afraid of innovation. After all, it is through innovation that their watch industry has achieved world leadership. In radio, they are ahead of their time: in the early 2000s, RSI (Swiss Radio International) moved to the web by dismantling the powerful shortwave transmitter at Sottens (500 kW) in 2004. Twenty years later they are ready to switch off FM for DAB (from 2024), but unlike Norway, they have prepared the transition methodically: widespread coverage of the territory and information campaigns to buy digital receivers. And artificial intelligence sees them as pioneers once again: while in the States they are announcing software, Colour 3, the third public radio network in French-speaking Switzerland, has already gone on air on 27 April 2023 with programmes made by AI.

Although the experiment lasted half a day, it was meticulously prepared for months, experimenting with ten types of artificial intelligence and selecting five of them, including ChatGPT. The texts of the programmes were generated by algorithms, the music composed by AI, and the digital voices of five female and male animators of the station, cloned by Respeecher, a company specialising in film productions, were put on air. Only the information was handled in the traditional way, with articles written and read by live editors. Speakers, however, can rest assured, because artificial intelligence, as Antoine Multone, head of Colour 3, pointed out, is ‘cold’ and cannot replace the creativity, improvisation, and humour of a human.

But the path is now marked out and the experiment is considered interesting by Pascal Crittin, director of RTS (Radio Télévision Suisse) because the energy that can be saved by entrusting the management of part of the programming to artificial intelligence can be concentrated on the originality of the content. Also, he adds that RTS and SSR (Société Suisse de radiodiffusion) want to use AI in an ethical manner, offering verified information and protecting the public from fake news. All of this is in the DNA of Couleur 3, which was one of the first Swiss radio stations to computerise its schedule, use samplers and, more recently, try out binaural sound, create social network videos and new musical currents before they spread.

ITALY: Will there be room for all radio stations on DAB?

The allocation of licences is approaching and we asked an expert what will happen. Pending final guidelines, as of today, those who broadcast on FM can participate (as members of a consortium, otherwise they will compete for the remaining space). Those who only operate in the digital band, on the other hand, have two options: buy an FM frequency or buy half the band that will be allocated to a radio station that is entitled to it

The allocation of DAB frequencies in Italy is approaching and the scarcity of radio resources will not allow all consortia to obtain them. As a result, not all radio stations will be able to have a channel, particularly those that do not have FM frequencies. With Massimo Lualdi, who with Consultmedia has been assisting hundreds of publishers on regulatory issues for almost thirty years, we take stock of the situation regarding the prospects and steps to be taken by traditional publishers and those who have taken advantage of the current availability of channels to bring their web radio to DAB.

A premise: in Italy, the digital band has two limits: the unused channel 13 (reserved by the Ministry of Defence for the VHF links used by the Army) and the interference problems raised by neighbouring countries, which limit the number of channels that can be used, aggravated by the Ministry’s absence at the coordination tables over the last decade, which have left Italy with ‘the crumbs’.

What timeframe is envisaged for the contest and the subsequent allocation?
It is difficult to answer since the final guidelines for participation in the calls for tenders have not yet been published by the Ministry of Enterprise and Made in Italy. It was thought that they would be published by the end of February 2023, resulting in the publication of the calls for tenders in the current month of March and with the deadline for the submission of applications within the following 30 or 60 days (it is not even known how long this will be), but this has not happened. I assume it will be soon so we can estimate that by the beginning of the summer, the ministry will be able to start the screening and, barring any surprises, conclude the allocation by the end of the year.

For how many broadcasters will there be space on DAB?
Since the draft guidelines indicated a maximum limit of 72 CUs (capacitive units: allows 12 channels with a bitrate of 96 kbps on a multiplex) for each broadcaster, but (rightly, to avoid DTT errors) not a minimum, it is difficult to answer. Theoretically, 36 CU (equal to 48 kbps per channel) is considered a suitable value to carry the existing analogue to digital. But since not all broadcasters will give up the maximum due, the picture is still undefined.

Will those operating on FM have priority in the allocation or only a higher score?
They will have it to the extent that only analogue licensees can participate in a consortium as partners. But if they have not done so before the tenders, they will have the same chance as independent, i.e. digitally native, providers.

Will a radio born on DAB still be able to broadcast? What steps will it have to take to avoid having to switch off and protect the investments made so far?
A few digital natives acquired analogue dealer status (by taking over the concession and FM plant in the region of interest). A few others have secured a 50% share of the 72 CUs due to an analogue dealer (allowing them to cut costs pro rata in the consortium). For the others, it will depend on the remaining spaces. As Consultmedia, we are convinced that the market will stabilise in the use of 36 CUs, which, if handled well from the point of view of the audio chain (source files, high-quality sound processing and Fraunhofer codecs), guarantee more than decent sound quality. With this in mind, all current independent providers in the experimental muxes should be able to survive.

Buy a concession and an FM channel? Some have already done so: will this new interest in FM drive up prices? (Which, as you write in the Newslinet magazine, have plummeted by 90% in recent years)?
Absolutely not. This is a transitory phenomenon related only to participation in tenders. In fact, we will see a new collapse immediately afterwards. I’ll say more: it is very likely that incentives will be provided at the ministerial level (at the instigation of Agcom, which has already expressed its opinion on the point) for the voluntary decommissioning of installations in exchange for a guarantee that analogue status will be preserved in digital form (hence the possibility of competing for contributions and other support measures, and of course of participating in consortia as members).

UK: HEART ATTACK LIVE

Suffolk's GenX Radio presenter Tim Gough dies on air — The BBC website dedicated a lengthy article, with testimonies from former colleagues who remember him for the time they spent together behind the microphone
Source

It’s as good a day as any in Ipswich, a Suffolk town where GenX Radio is based, a web station that within a year has been so successful that it has taken the leap into the airwaves, submitting an application to Ofcom to open a DAB channel (the authorisation will come a few days after Tim’s death). Even though it has no competition, because it is the only commercial station in the region, it needs to upgrade its palimpsest in order to land in the digital band. So it recruited a veteran of the airwaves for its most important programme: the breakfast slot, which between 6am and 9am takes listeners from waking up to resuming their activities. And Tim Gough is an exceptional presenter: he has decades in the business behind him and, above all, began his career in 1986 at Radio Orwell, a station based in Ipswich (transmitted on 1170 kHz on medium wave and 97.1 MHz on FM).

A morning like any other

The sun rose at 7.37am. The sky is grey but not cold, it’s 13 degrees. It’s Monday, a new week begins and it’s time to get the energy going. Tim is happy. These are the first broadcasts he is conducting after ten years away from the microphones. He lives 30 km from the station and to avoid travelling to the studios before dawn he has equipped himself at home. He has been on the air for almost an hour when he plays Grey Day by Madness, a ska group that in 1981 with this song parodied a grey morning like that, but in which you still have to get up and drag yourself like zombies to the office after a night of revelry.

Suddenly the music stops

Grey Day is a track full of energy, evoking for Tim the years when he took his first steps at Radio Orwell, in 1986, and he thinks it’s the right push to face a new cloudy week. But shortly afterwards, at 7.50, the music suddenly stops: Tim is taken ill, probably from a heart attack. The ambulance arrived and the paramedics tried to revive him, but after 25 minutes of effort, they had to throw in the towel. Tim left live. As soon as the news spreads, the emails start arriving: hundreds of messages of love. After all, Tim is a well-known personality: after his debut on Radio Orwell in 1986, he became a specialist in morning host. He moved on to Saxon Radio and SGR-FM and made appearances on Smooth Radio, several stations in the East Midlands and other national radio stations. The BBC article collects several testimonials from former colleagues, who agree that he is a friendly, funny and very talented guy. (Written by Fabrizio Carnevalini)

SPAIN: WILL THE CONSTITUTIONAL COURT OPEN UP TO DIGITAL RADIO?

The Collserola tower, a daring construction designed by British architect Norman Foster in 1992 for the Olympic Games, is 288 metres high and also houses the antennas of the DAB multiplex for Barcelona — The Collserola tower, a daring construction designed by British architect Norman Foster in 1992 for the Olympic Games, is 288 meters high and also houses the antennas of the DAB multiplex for Barcelona

The Iberian country is lagging behind in the transition of radio to DAB. Eighteen years after the activation of multiplexes, digital broadcasting seems not to have emerged from the experimental phase: they are active in Madrid and Barcelona, and a few other cities, still broadcasting in the old standard DAB and not in DAB+. The few programs carried are those of Radio Nacional de Espana (Radio 1, Radio 5: Radio Clásica, and Radio 3 remain excluded), and the main networks (the missing ones are, for example, Cadena Dial, Los 40, Rock FM). Similarly to FM, where inertia in granting authorizations has proliferated illegal frequencies, to which networks also resort, unauthorized multiplexes have been turned on. The number of official ones active mainly in tourist areas (the Costa del Sol and Canary Islands) is doubled.

Avalanche of appeals

Given the competition made to official radio stations by unauthorized ones, many broadcasters interested in digital broadcasting have appealed to the Spanish Constitutional Court, which between September and October 2022 upheld sixteen “recurso de amparo”, which added to those already pending bringing the total to 22. This ”recurso” is a legal formula that allows Spanish citizens to appeal to the supreme court when they believe constitutional norms have been violated. Giving an accurate picture of the situation is the magazine Panorama Audiovisual, which reconstructs its evolution since 2018 when broadcasters began turning to autonomous communities to apply for authorizations. Since some regions have refused, despite having an obligation to grant them, even though they did not proceed with the allocations, a law firm has recommended appeals to the Constitutional Court. Will they be upheld? Let’s keep our fingers crossed! (Written by Fabrizio Carnevalini)

TECHNOLOGY: RADIO IN TUNNELS/Part 1

If a tunnel is not equipped with appropriate communication systems, the car radio remains mute
Source: Photo by Stain_Marylight from Pixabay

When travelling by car and driving through a tunnel, the signals picked up by the radio are quickly attenuated. Only when the repeater is close by or has its antennas pointed towards the longitudinal axis of the tunnel, the waves are able to make their way through and you can keep the station tuned for longer, but then the signal disappears. Those travelling by car may also like a few minutes of silence, but in the event of an accident, the signal blackout would prevent the rescue vehicles from communicating with the outside world. Therefore, for safety reasons, communication systems are installed in the longer tunnels that can carry emergency signals and allow FM and DAB radios to be heard.

What the law says

If a vehicle stops in a tunnel due to a breakdown or following an accident, emergency vehicles must be able to communicate with the outside world.

The problem of communications has been addressed by the legislator, who in Europe has stipulated (with Directive 2004/54/EC) that in tunnels longer than 500 metres the minimum safety requirements of the trans-European road network must be met. If the tunnels exceed 1,000 metres in length or are located on particularly busy arterial roads (with more than 2,000 vehicles passing through), the road manager is obliged to install special radiocommunication systems that allow contact between emergency vehicles (ambulances, breakdown vehicles, fire brigades, road maintenance company vehicles) and the police.

Technology

Cable or radio wave transmission systems are used for communications. In the first case, ‘slotted‘ coaxial cables (with openings drilled at regular intervals, from which the signal comes out) are laid along the tunnel. The system has the advantage that it can be used to simultaneously transmit and receive on the different frequencies used by emergency vehicles, and to allow to listen to radio in the car. But since signals propagate differently depending on their frequency, corrective measures must be taken and amplifiers are introduced at regular intervals to compensate for attenuation. This requires careful design and a lot of maintenance (with increased costs). However, the system is delicate and vulnerable to fire and accidents, and there is a move towards radio wave transmission. (Written by Fabrizio Carnevalini)

NEW ZEALAND: ENHANCED SHORTWAVE BROADCASTING FOR THE PACIFIC

Radio New Zealand's current outdated transmitter will be replaced: the New Zealand government allocated NZ$4.4 million (about US$2.5 million) in May — Radio New Zealand’s current outdated transmitter will be replaced: the New Zealand government allocated NZ$4.4 million (about US$2.5 million) in May 2022

As of September 2022, New Zealand’s public broadcaster (RNZ) has increased its shortwave broadcasting hours aimed at the Pacific region. The four morning hours, suspended in 2016, restarted thanks to new government funding, on three frequencies: at 5 a.m. local time on 7425 kHz, 6 a.m. on 9700 kHz, and 8 a.m. on 11725 kHz. The most listened news program is also repeated by the BBC Pacific Service. Shortwave broadcasting, largely abandoned since the 1990s at the end of the Cold War, still remains the most effective means of covering very large areas. As in the Pacific Ocean archipelagos, where many communities still use the old analogue radios with the SW (Short Waves) band to inform themselves.

It also broadcasts digitally

In the middle hours of the day, however, the station broadcasts with the DRM standard: a digital transmission system that eliminates all the typical hissing due to atmospheric and electromagnetic interference. The audio is stereo, but it is out of reach of the old analogue radios. In order to receive the DRM you have to buy a receiver that is set up to decode the digital signal, which costs between 50 and 100 euros. Alternatively, the signal is broadcast by satellite from Intelsat 19 on C-band: coverage extends from Singapore eastward to the Cook Islands, including Fiji, Tonga, Niue and Samoa.

SPAIN: TURNING OFF FM AND MW TO SAVE ELECTRICITY?

Citing the examples of Switzerland and Norway, the Compromís party has asked the Pedro Sanchez government to consider switching to digital broadcasting by abandoning frequency modulation
Source

To cope with a possible energy crisis, Compromís, a political party in the Valencia region, has asked the government to consider among emergency measures whether to change the broadcasting technology for radio stations. Switching to DAB, as Norway did in 2017 and Switzerland plannes to do at the end of 2024, could reduce electricity consumption by up to 90 %, according to Carles Mulet, the party’s spokesman in the Senate. But first Mulet proposes rationalizing the medium waves by employing the savings in the implementation of a DAB network and finally turning off FM. He then cites the costs declared by Radio Nacional de España after the parliamentary question submitted by the party in March 2022: between maintenance and expenses at transmitters in 2021 the medium waves absorbed 6,823,026 euros, and 6,287,503 euros were spent for the FM network.

BETWEEN SAYING AND DOING

**Research by OFCOM (Swiss Federal Office of Communications) shows that in the last quarter of 2021, three out of four people listened to radio digitally while FM continues to lose importance**

Shutting down a band takes years of planning (while the energy crisis could occur in a few months, with the arrival of winter) and if the transition is not well managed it can cause ratings to plummet. As was the case in Norway, where it was public radio that decided to switch to DAB (also not to renew an outdated and expensive ground network: commercial and community broadcasters are still active) and the loss of audience five years later has still not been fully recovered. Switzerland, on the other hand, is a small country that between public and private radio does not reach 200 stations but has been preparing for the switch-off for years, with advertising campaigns in favour of digital radio so much so that now only 14 out of 100 people listen only to FM. In Spain, on the other hand, there are 163 medium wave transmitters (of which 103 are public and 60 commercial) and approx. 2,500 radio stations with over 6,000 transmitters on FM, of which it is estimated that at least a thousand are unlicensed, and only a few experimental DAB radio stations in Barcelona, Madrid and in a few cities (as well as a few unlicensed private muxes).

TECHNOLOGY: The evolution of receivers

An article written by a researcher from EuroScience (European Association for the Advancement of Science and Technology), traces the evolution of radio receivers. Debojit Acharjee, a software engineer and “geek,” as the author likes to call himself, starts from the prototypes invented by Guglielmo Marconi to digital ones. Novelties that have come since the 2000s: from the first pocket radio for listening to the DAB digital band (launched by Pure in 2003), to one for listening to broadcasters streaming on the Web (3com’s Kerbango, which debuted in the 2000s). To arrive at those without the tuning knob, there are the SDRs (Software Defined Radio): receivers that in their more advanced versions (but sold at a price comparable to that of the “transoceanic” radios of the 1970s, such as the Grundig Satellit) allow you to see the full spectrum of the FM band and record 24 MHz. The impetus to innovate? Behind every discovery is the improvement in listening quality, such as that which prompted General Electric in 1940 to invent frequency modulation, demonstrating that it was less susceptible to electromagnetic interference than amplitude modulation, used on medium waves.

UKRAINE: MEDIUM WAVE SWITCHED BACK ON TO SUPPORT FM NETWORK

To counter possible damage to its FM repeater network, Ukraine has switched back on some radio stations operating on medium waves. They had been switched off in 2018, like so many energy-intensive installations supplanted over the years by the frequency modulation network, which has the advantage of offering better audio quality. But reactivating them has become strategic because they are installations that can serve large areas of the country and are often located in areas far from those affected by the conflict, and could operate undisturbed. Of the six reactivated, mainly between 24 and 26 February 2022, only one was damaged. They all broadcast the first programme (UR1 Pershiy Kanal).

Rumours coming from the back

UK: NO FM SWITCH-OFF UNTIL AT LEAST 2030

In the UK, frequency modulation will not be switched off, at least not for the next ten years, media minister Julia Lopez said a few days ago. Although it is estimated that analogue radio will only account for 12 to 14% of all radio listening in 2030, FM remains popular with many listeners, particularly the elderly or vulnerable, who drive older cars or live in areas with limited DAB coverage. The fate of mediumwave broadcasters is sealed: with 3% of all listeners, they will have to plan to switch off, to reduce the costs of a substantially duplicated network. There are currently more than 300 analogue stations operating in the UK and over 570 in DAB. Sixty percent of all listening comes from DAB or other digital platforms. Programme offerings are expanding as new franchises in DAB are giving many small local stations the opportunity to broadcast.
