TECHNOLOGY: RADIO IN TUNNELS/Part 1

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.

Cable or radio wave transmission systems are used for communications. In the first case, ‘slottedcoaxial 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)

ITALY: TUNE IN TO RADIO SAN MARINO IN THE CAR AND THE RUSSIAN FLAG APPEARS

A few days have passed since the outbreak of the conflict in Ukraine. One morning, a listener of Radio San Marino is stunned: on the car radio screen of his Audi, a new generation model displaying the brand logo of the stations tuned in, the Russian flag appears. Yet the programme he is listening to is precisely that of Radio San Marino. He thinks of action by hackers: these are days when the invasion is taking its first steps, the information is confused but the propaganda is very active. He wonders what it could be about: in the previous days, nothing was visible. He takes a couple of photos and emails them to the broadcaster. The message reaches the technical management, which turns to an expert.

There was already an anomaly

Let’s go back two months. Radio San Marino has been experiencing problems with some car radios for some time: their brand logo does not appear. Therefore it commissions an investigation from Radio Data Center, a German company specialising in new-generation multimedia systems that display the broadcasters’ logos. Research shows that the problem is confined to the brands of the Volkswagen Group (including Audi, Lamborghini, Porsche, Seat, Skoda) and Ford. During the research, a technical incompatibility emerges: the station is not using an identification code reserved for the San Marino state, as prescribed by international regulations. It has inserted a number reserved for Italy in the equipment that generates the RDS: a correct one is identified and communicated to the technical office. The broadcaster repositioned itself correctly in February 2022 and… a few days later, the picture of the screen with the Russian flag shows up.

What had happened?

Radio Data Center does the first test on an Audi Q5 at the Reggini dealer in Falciano: nothing appears on the screen. Not even the Radio San Marino brand, but that’s normal: the RDS change was announced 30 days ago, but since the car is not connected to the Internet, you have to wait for the update to become available, download it onto a memory stick and do the upgrade (but the company is late: it is still suffering from the slowdowns caused by the pandemic and has not released it for some time). The anomaly is therefore confined to older-generation, Volkswagen-made car radios and shows on the screen Radio Rossii, the most important Russian state broadcaster, which has the flag in its logo. The update will correct this.

But the devil got in the way

On the broadcaster's website, with streams of TV and the two radio stations, you can see at the top the brands of Radio San Marino and the second Classic channel

The change, announced in February, is on the waiting list: with tens of thousands of radios to chase, and constant changes, those managing the logos have so many backlogs. The request is examined after six months. But there is a setback: due to an error, only the data of the second network Radio San Marino Classic (which has similar problems) is updated. It’s therefore necessary to wait for the next update, scheduled for December 2022. (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

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.

UNITED KINGDOM: BUREAUCRATIC ERROR, COVID, SITE TO BE DECOMMISSIONED, POWER CUT… IT CLOSES

BUREAUCRATIC ERROR, COVID, SITE TO BE DECOMMISSIONED, POWER CUT... GRAVITY FM CLOSES
The broadcaster bid farewell to its listeners by posting on Facebook a summary of the vicissitudes it went through

All that was missing was an earthquake and locusts (John Belushi in The Blues Brothers): what happened to Gravity FM is textbook for the flurry of bad luck that forced it to close. The staff of the station, which had been on air since December 2008 on 97.2 MHz in Grantham (Margareth Thatcher’s hometown, a town of 35,000 inhabitants 40 km from Nottingham), recounts this on its Facebook page. Gravity is a community station, it advertises, but it has been in bad shape for some time and another company was formed to take it over. But in the transfer of the licence something goes wrong: the UK’s airwaves regulator, Ofcom, makes a mistake. That forces the station to take a long and expensive legal route to get it corrected.

Covid-19 arrives…

It’s November 2019. Two months later the pandemic breaks out. On 23 March 2020, the first lockdown is decreed in the UK: within a few weeks, advertisers suspend advertising campaigns. The station’s revenues plummet by 70 per cent, but the radio station cannot suspend broadcasts, temporarily shutting down as companies do. It performs a public service and the law obliges it not to interrupt it, even if it is forced to work at a loss (the state subsidies are not enough to get it back on its feet). However, the legal process is still long: it ends in November 2020.

…and they also cut the power

As if that weren’t enough (it’s April 2021), the radio station learns that the Malting, the old malting factory in the town that houses the transmitter and antennas on its roof (52 metres high), is being decommissioned. The frantic search for an alternative begins: lighting the city is not easy, due to orography problems. And then the regulations on transmitter sites have recently changed: there is uncertainty and building owners do not feel up to hosting new antennas. In January 2022 comes the warning that the power cut is scheduled for the end of February. The last days of the search are feverish. But the contractors get on with the job and… remove the power cables weeks in advance, shutting down the signal. Radio throws in the towel. (Written by Fabrizio Carnevalini)

FRANCE: EUROPE 2 RETURNS AFTER FIFTEEN YEARS

EUROPE 2 RETURNS AFTER FIFTEEN YEARS
Now Europe 2 will return to “reaffirm its original mission: to nurture the link between artists and audiences, through its musical offer aimed at adults and young adults, by investing heavily in musical events and promoting live sessions”
Source

From January 2023, Europe 2 will return on Virgin Radio‘s 243 frequencies: this is one of the changes envisaged by the reorganisation of the Lagardère Group (of which the Europe 1 and RFM radio networks are also part) announced in June 2022 when Vivendi took control. Europe 2 is a historic brand, which had given way to Virgin Radio in January 2008, after 20 years in business. The agreement with Virgin, which covered frequencies in France, Belgium, Switzerland, Andorra and Monaco, had been signed in December 2007 by Sir Richard Branson, who had appeared on the Champs-Elysées dressed as Father Christmas for the occasion. Originally Europe 2 was a programme distributed to broadcasters. It became a network but left room for local programmes. Now, for Arnaud Lagardère, President and CEO of the group, and Constance Benqué, who heads the news hub, Europe 2 will return to its original mission: to connect audiences and artists.

ITALY: DIGITAL FREQUENCIES PLANNED

The map produced by Agcom divides the Italian peninsula into various interference zones: in each one, international coordination with neighbouring countries exposed to possible interference is required

After years of waiting, the long-awaited planning of the DAB band by Agcom has arrived. The regulator waited for the channels in band III to become free with the switchover to DVB T2 and released the plan at the end of July 2022. There was no shortage of controversy, fuelled by rumours of the switch-off of hundreds of FM frequencies on the Adriatic coast due to interference caused to broadcasters in Slovenia, Croatia, Montenegro, Albania and Greece. A problem due to technical reasons (installations in the mountains point towards centres on the coast), to the high powers used (Italy’s historical problem) but above all to tropospheric propagation. This is a meteorological phenomenon that occurs mainly in summer, when the lower layers of the atmosphere, compressed by high pressure, become denser and reflect radio waves.

Did they just try it?

The specialised periodical Newslinet reported in July 2022 that there was a plan to shut down hundreds of channels on the Adriatic coast because they were disturbing foreign radio stations. It is a problem that has been known about for decades and is due to the fact that since 1990, after the freezing of the airwaves brought about by the “Legge Mammì“, no planning has ever been done for the FM band in Italy. And the interference situations, not well managed by Italy also due to the absence (lamented by the associations) of the Italian delegation at the European planning table, now leave very narrow margins for manoeuvre. Hence the attempt to induce broadcasters to exchange DAB-FM or to scrap it in order to fall within the parameters of the Geneva regulations.

Associations on different levels

The position of the associations varied. Among them, Aeranti Corallo, which has always pushed to accelerate planning, continues to be critical, reiterating that the frequencies are not sufficient to allow the transition from FM to digital. On the other hand, Confindustria Radio Televisioni applauds the planning: will it be because the networks it represents already have one or more channels in the DAB band? But what does the plan say? It confirms the three existing national networks (Rai, DAB Italia and EuroDab, for a total of about 50 channels) and envisages 54 local ones with regional coverage, of which 27 can be broken down into sub-basins, and another 36 in the local area to cover one or more provinces. Beyond the technical data, in some provinces there could be space for six multiplex (for a total of about 120 channels), but not in the southern Adriatic regions, due to interference problems.

USA: FORMER STATION MANAGER NOW LEADS STUDENT RADIO WHERE HE STARTED HIS CAREER

FORMER STATION MANAGER NOW LEADS STUDENT RADIO WHERE HE STARTED HIS CAREER

It comes full circle, Michael Mallace told Radio Ink, a US radio newsmagazine. He will direct KVIT-FM, the high school station in Chandler, a city in the Phoenix metropolitan area, where he started his career. In fact, the East Valley Institute of Technology (EVIT) has appointed him as general manager of 88.7 FM The Pulse, the high school radio station that aims to engage students to acquire the necessary skills to make their way in the world of radio. Over the past 30 years, he has run various radio groups in the Arizona capital, not just chasing ratings and profits, but valuing people and nurturing talent.

A very American phenomenon

The Pulse is one of more than four hundred US campus radio stations (one in 15 of the approximately 6400 active FM stations) that have been in existence since the 1960s when the FCC (Federal Communication Commission, the US airwaves regulator) began issuing licences. They operate with an identifier (call number) similar to that of commercial and public stations. In Canada there are 52 of them, in FM and even on medium wave: the first was CJRT, from the Ryerson Institute of Technology (Ontario Department of Education). Known as Jazz Radio, it started in 1949 on 88.3 MHz with a power of 3 kW and today is on 91.0 MHz with 40 kW. The United States and Canada have the largest number of FM student stations, but there are such stations in over 40 countries. Often they operate only on the web because regulations do not offer them space on the airwaves.

Talent hubs and trendsetters

Working in college radio is part of the student experience. Stations are run completely independent but can make use of contributors from the community to which they belong for programmes. Some are set up to train professional radio staff, others to make educational programmes or to be an alternative to commercial and public radio. They often uncover musical trends or emerging artists before they make a name for themselves. One example among many? Music promoter Marco Stanzani writes that Anderson Paak, a pop artist of worldwide notoriety, had been noticed when he was still in the early stages of his career by Italian rapper Mondo Marcio thanks to tracks broadcast on a US college radio station. So much so that since 2010, with his agency Red&Blue Stanzani, he has organised Uniweb Tour – a real live acoustic live tour on the web radios of major Italian universities – to promote the artists he covers.

FRANCE: THE GOLDEN YEARS OF LOCAL RADIO IN RENNES

Forty years ago, the French state broke the monopoly in the FM band, authorising the emergence of private associative broadcasters. At that time, the FM band was populated by a few channels: the public ones of Radio France and a few private ones, such as Europe 1 and RTL. From 9 November 1981, the phenomenon exploded, immediately making radio a popular medium: within a year, there were two thousand free radio stations. The next step came in 1984 when advertising was authorised, and radio stations could choose between two organisational formulas: remaining an associative broadcaster, relying on state subsidies, or standing on their own two feet, becoming a commercial station living off the revenue from commercials.

The epic told in a book

In Rennes, there were two pioneers: Gaby Aubert, a butcher’s boy turned bistro owner, who launched Radio Rennes, which is still in operation today, and Pierre Giboire, a 23-year-old student who created Fréquence Ille on 14 July 1981: it was an immediate success, quickly becoming one of the radio stations that symbolised the liberalisation of the airwaves. Not much time passed and in the Breton capital, other stations followed the path opened by the pioneers: Rennes FM, Radio Congas, and Radio Vilaine. They are mainly music stations, each distinguished by its own style. It is of this creative period that ‘Il est libre Max‘ (in homage to the name of the first song broadcast by Fréquence Ille), a book written by Yvon Lechevestrier, a former journalist for the French daily Ouest-France, is about. With testimonies and period illustrations, it brings the fabulous 1980s back to life.

Standardisation arrives in the 1990s

The golden age of local radio continued until the end of the decade, interspersed with episodes from the city’s history. But after the initial enthusiasm, business began to take hold: the most important commercial radio stations, such as NRJ, grew and became national networks. In the 1990s, with the first economic difficulties, most of the pioneers threw in the towel and many stations were absorbed by the networks. The FM band is still very musical, but also, often, very commercial.

Forty years later, the radio scene is still vibrant: at the end of 2020, according to the Conseil Supérieur de l’Audiovisuel (CSA), there were 1,021 private operators and more than 6,000 frequencies. The book, published by AR Editions Collection, costs EUR 29 and can be ordered from arcollectioneditions@gmail.com or directly from the author at ylechevest@gmail.com.

The WRTH is an indispensable reference for orientation in radio listening. Initially, the book addressed DXers with an interest in shortwave and the “tropical bands”, as well as medium wave. The FM band, as used by the national / public broadcasters, was also covered, but not completely: the liberalisation of the airwaves, which began in Italy in 1975 and spread throughout Europe, saw the emergence of thousands of stations in just a few years, making it impossible to publish their tens of thousands of frequencies in WRTH. For reasons of space, WRTH was often limited to the major networks (12233 stations are active in the Old Continent alone, of which 8786 are commercial). Full data can be found on FMLIST (founded in 1986 by Günter Lorenz), which under the management of Radio Data Center has strengthened the worldwide team of contributors, expanding the database to a professional level, e.g by producing an identikit for each radio station. Future editions for WRTH will make comprehensive use of data from FMLIST. This synergy will make the WRTH also more attractive to professionals interested in a global directory including FM and all variants of digital broadcast (DRM, DAB, HD Radio).

It was the El Guardián, a newspaper in Costa Rica, that shed light on the amounts paid to the state by radio stations as frequency licence fees. It wrote to the press office of the Ministry of Science, Innovation, Technology and Telecommunications (MICITT), which provided the list of stations with the relevant amounts in Costa Rican colón (it takes 667 for one US dollar, at the current exchange rate). The amounts are small, considering that the annual average income in 2020 was USD 12,076.81 and the monthly minimum wage USD 402. FM stations pay an average of 6,000 colóns per year (about 9 US dollars); 1,000 to 2,000 for medium-wave broadcasters (1.5 to 3 US dollars) and 1,500 to 5,000 for transfer bridges (2.25 to 7.50 US dollars). Here is the list of broadcasters, whose names are listed in the concession.
