EU vehicle digital radio legislation

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!

Silicon Chip: Building a AM/FM DAB+ tuner

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

[The January 2019 issue of the Australian Silicon Chip magazine] commences a series of construction articles on building your own DAB+/AM/FM receiver. Australia was the first country to start permanent high powered DAB+ broadcasting which was in Aug 2009.

It is now extensively used in Europe but in the UK there are only 4 program streams in DAB+ the rest are in DAB which uses a less efficient audio compression and poorer error correction for noise and reflected signals.

Could Norway and NATO clash over DAB frequencies?

(Source: NewsInEnglish.no via Mike Hansgen)

Thousands of ordinary Norwegian citizens aren’t the only ones frustrated and dissatisfied after Norway’s forced transition to DAB radio. It meant shutting down FM radio, and now NATO may find itself in conflict with the civilian DAB frequencies it was granted for exercises in Norway.

Norwegian politicians and authorities were reportedly warned before they imposed DAB on the civilian population that it could cause problems in crisis situations.

Newspaper Aftenposten reported on Tuesday that civilian radio and the military use the same frequency of 225-245 MHz. NATO had long ago pointed to that frequency as its own when Norway decided to switch from FM to DAB and Norway’s national communications authority (Nkom) allocated space on the network.

[…]The biggest test will come this fall, when around 40,000 soldiers, 130 military aircraft and 60 vessels from 29 countries will take part in NATO’s huge military exercise called Trident Juncture. Asked whether there will be problems with radio communication, divisional director at Nkom John-Eiving Velure gave Aftenposten an “unconditional yes.” Per-Thomas Bøe, spokesman for the Norwegian defense department also confirmed that NATO can override civilian DAB radio if it needs to.

That means civilian radio broadcasts can be cut out, like they allegedly were during the NATO exercise Dynamic Guard outside Bergen in February. Military communication among aircraft, vessels, army divisions and the commando center can also be disturbed.[…]

UPDATE: SWLing Post contributor Mike Barraclough points to the following article in telecompaper and notes:

The Norwergian Communications Authority has diplomatically stated that this article “has caused unnecessary concerns.”

Nkom denies DAB frequency use is at odds with NATO usage

Norwegian communications regulator Nkom said an article by newspaper Aftenposten reporting conflict with NATO over the use of airwaves normally reserved for DAB radio has caused unnecessary concerns. The regulator says Norway can decide for itself how to use frequencies, providing there is no breach of international agreements that it has signed. Anyone using radio frequencies in Norway must obtain a permit from Nkom, even the national armed forces and Norway’s NATO allies.

Nkom said use of frequencies for the Norwegian DAB network has been coordinated internationally and agreed with more than 30 European countries. Nkom would not allow anyone to use airwaves if this would disrupt normal broadcasting services.

UK digital radio listening now eclipses analog according to study

(Source: Radio Mag Online via Marty Kraft)

LONDON — In the United Kingdom, the use of digital sources for radio has reached 50.9%, up from 47.2% a year ago, accounting for the majority of all listening for the first time, according to RAJAR Q1 2018 data.

“With the 50% digital listening threshold now met, it is anticipated that the UK government will undertake a review to assess digital radio progress and determine next steps in due course,” according to a Digital Radio UK press release.

Digital listening share is comprised of listening across all digital platforms: DAB in homes and in cars, apps and online (which includes the growing number of smart and voice-controlled speakers) and DTV — and this is the first time that listening to digital has been greater than analog platforms — FM and AM.

[…]The UK’s three leading radio broadcasters — the BBC, Global and Bauer, which collectively account for over 90% of UK radio listening — are “fully committed to delivering a digital future for radio and look forward to working with government and the supply chain to continue the transition to digital radio.”
