The image of the advertising campaign informs of the switch from medium waves to FM Source
Within six years, more than 90% of Japan’s commercial stations (44 out of 47) will leave medium-wave to switch to frequency modulation. In September 2028, only three stations will remain active in northern Japans Hokkaido and Akita Prefecture. But the airwaves will begin to empty from next year: the first channels will be turned off in the fall of 2023. The advertising crisis has prompted broadcasters to ask the communications ministry to migrate to FM to reduce operating costs: AM systems are energy-intensive, maintenance expenses are high, and antennas at least 100 meters high are needed to transmit. The last to leave the airwaves will be three Tokyo-based broadcasters-TBS Radio, Nippon Cultural Broadcasting and Nippon Broadcasting System-and some will continue to keep AM transmitters on after 2028. In Japan, the FM band goes from 76 to 95 MHz because the higher channels, before the digital switchover, were occupied by television. Written by Fabrizio Carnevalini
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

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
The cable carrying the radio signals was severed by a TIR, interrupting radio listening Source
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 byFabrizio Carnevalini)
The shot sent by the reader to Radio San Marino. The image is not of good quality and retouches have been made to mask the face reflected on the screen. We apologise, but it was not possible to trace the listener and take a professional shot Source: Radio San Marino
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
Founded in 1990, Radio Rossii is part of the public broadcasting company VGTRK and is Russia’s leading broadcaster: it has regional branches throughout the country and 1800 repeaters Source
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 brand logos of Radio San Marino and the second Classic channel Source
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 byFabrizio Carnevalini)
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 Source
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
RNZ’s shortwave broadcast schedules can be seen on this page. The programs are also distributed via satellite Source
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 bysatellite from Intelsat 19 on C-band: coverage extends from Singapore eastward to the Cook Islands, including Fiji, Tonga, Niue and Samoa.

The broadcaster bid farewell to its listeners by posting on Facebook a summary of the vicissitudes it went through Source
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…
The article in the Grantham Journal, a daily newspaper published since 1854, shows the headquarters with the sticker on the large window Source
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
On the MB21 site, created by Mike Brown, we found a photo of the old malt factory that housed Gravity FM’s antennas Source
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 byFabrizio Carnevalini)
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 243frequencies: 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.
