Radio Republik Indonesia (RRI) has just conducted measurements proving the DRM in FM is spectrum, energy efficient delivering audio and text in superior quality without any interference even in very crowded FM environments.

RRI has always been on the forefront in the field of radio broadcasting and on-line radio.
The successful testing and measurements carried out in July came on the back of pioneering DRM deployments in the FM band.


On 10 June 2020, a digital radio transmitter was installed and commissioned by RRI at Pelubharan Ratu in Sukabumi province, West Java. For this purpose, the Digital Radio Mondiale (DRM)[1] digital radio system was used: this innovative step meant this is the first ever digital radio broadcasting station in Indonesia and in Southeast Asia.

Currently, the Pelubharan Ratu digital radio station is broadcasting three programmes in digital form, RRI Pro 1, RRI Pro 3 and, through its digital technology, news and current affairs information in textual form (in writing) in Bhasa Indonesia. The data provision is done through a digital system known as Journaline. The possibilities are immense as the system can cater to news and other information spanning 64,000 pages.

The second such digital radio transmitter was installed and commissioned on 11 June 2020 at Pantai Labuan in Banten Regency, West Java. Following this, the third DRM FM digital radio transmitter was installed and commissioned in July 2020 in Cilacap, Java Tengah province. These stations also provide similar programmes and digital services. In addition, by August 10, RRI plans to install and commission two more DRM FM transmitters in Painan, West Sumatra and in Labuan Bajo, Nusa Tengarah Timor province in eastern Indonesia.

In July RRI conducted the evaluation of trials and measurements of the Digital Radio Mondiale (DRM) technology in Pelabuhan Ratu area, Sukabumi, West Java, an area often struck by natural disasters.

These activities carried out on Wednesday (23/7/2020) and (Thursday (24/7/2020) were conducted in preparation for the implementation of digital radio.

DRM is an open all-band standard digital audio broadcasting radio technology recommended by ITU and ETSI (EN 302 245 and ES 201 980). DRM has several features and benefits including the incorporated feature of Emergency Warning Functionality (EWF).

DRM can be a digitisation solution both in the MF radio frequency band, or VHF Band II (FM). Irrespective of band, since the DRM standard is one, each DRM radio frequency channel can accommodate up to three broadcast programs (audio) along with text data (presented as news media, advertising, public information, and so on).

DRM is both spectrum and energy efficient and delivers local, regional, national and international coverage. Unlike analogue DRM can be used to achieve broader coverage using the Single Frequency Network (SFN) feature.

DRM can be used on the MF radio frequency bands using the same bandwidth as analogue (AM) and this was successfully demonstrated in Indonesia during the Bogor and Bali trials.

If DRM is used in the VHF Band II it only utilises a 96 kHz that can accommodate up to three audio channels and one data channel. This was also demonstrated by RRI in their trial conducted with the DRM Consortium in Batam. So, half the spectrum for up to three audio channels and one data channel, rather than one analogue audio only programme in FM.

In Indonesia FM is widely used in large cities, so there are not many FM radio frequencies available now. To avoid interference between FM radio broadcasts, the FM broadcast radio frequency channel is ideally separated by 400 kHz (adjacent-4). As DRM can fit in these guard spaces DRM can be a solution even in the cities with a very congested FM spectrum.

The DRM for FM RRI measurements in West Java were carried out for two days, namely 23 and 24 July 2020. The first day, they started with six Test Points (TP), namely TP1 on Karang Hawu Beach, TP2 Karang Papak Beach, TP3 Kadaka Beach, TP4 Vihara Nam Hay Kwan Se Im Pu Sa, TP5 Batu Bintang Beach and TP6 Pantai Loji.

The sixth test point location was obtained based on the results of simulated computer predictions of radiation coverage of an analogue 1 kW FM transmitter.

Measurements were aimed at technically evaluating DRM transmissions and features that can be broadcast through DRM transmitters.


Based on the results of the field measurements obtained in the six test points covered by the 1kW transmitter it was noted that these can be served with only 50 watts of DRM power delivering throughout a good DRM audio quality. In testing a simulcast broadcast using 1 kW and 800 Watt with spacing distance 150 kHz between the middle frequency FM and DRM, the measurement showed no interference between FM and DRM. The DRM quality was at least equally good to FM, but the sound quality of DRM was even better than FM.

The field test results are thus consistent with the ITU-R Recommendations BS. 1114 and BS. 1660. The next measurement is scheduled to be held at RRI Central Jakarta in August 2020.

BBC announces all time record global audience

The BBC's global reach increased by 11% year on year in 2020 to 468.2m people a week - the highest number ever.

BBC News accounts for 438.4m of the total with an annual increase of 13%. Digital platforms are key to the success, with an increase of 53% in BBC News users. A total of 151m users now access BBC News digitally according the annual Global Audience Measure which measures how many individuals the BBC reached weekly with its news and entertainment content in the year 2019/20.

Tony Hall, BBC Director-General, says: "We are without question one of Britain's strongest and best-known brands, synonymous with quality and accuracy worldwide. Our international news services rank first for trust and reliability and the World Service remains a beacon of democratic values. Independent research shows that there is an exceptionally high correlation between places where people are aware of the BBC and places where people think positively about the UK. More than that, the BBC helps UK trade. This has perhaps never been more important. The UK will forge a new relationship with the world in the decade ahead, built on an ambitious vision of 'Global Britain'. Success will mean drawing on all our considerable international assets, and that means unleashing the full global potential of the BBC."

In late March 2020, as the Covid-19 virus spread and trusted sources of information were in demand, BBC News recorded the highest reach of any international media organisation in the world with 310m people accessing coverage across 42 languages.

BBC global content is increasingly popular on global platforms like Youtube with a 129% increase in audiences to 47m a week - overtaking Facebook with a 31% increase to 43m. Twitter reach has doubled to 6m and Instagram also reaches 6m weekly.

Other highlights of the 2020 Global Audience Measure:

- BBC World News channel made significant gains to reach 112m - with growth in the Americas at 50%.  

- BBC World Service languages up 13% to 292.1m with a big uptick in digital engagement among audiences aged 15-24 who now make up a third of the total. BBC News Hindi is now the second most popular service with 25m - behind Arabic with 42m (+67%). BBC Chinese saw an increase of 141%, Russian is up 32% and BBC Mundo 40%. Other big percentage increases include Serbian (+327%), Yoruba (+166%) and Afaan Oromoo (+143%).

- BBC Studios increased reach by 5.8m to 49.1m up 13%.

- BBC World Service English audiences up by 8% to 97m. The Global News Podcast remains the BBC's most popular with audiences approaching 1m a week. Italy contributed 1.4m new listeners on DAB radio.

- BBC Media Action - the BBC's international charity that helps to strengthen governance, improve people's health and humanitarian response - saw an increase in audience of 4m to 18m.

New content funded by the UK government's World 2020 initiative attracted new audiences, with Sport Africa - including extensive Premier League coverage; Africa Eye with groundbreaking investigative journalism; and What's New for young African audiences performing particularly well.  

The top 10 countries by BBC News audience are:

India - 60,400,000
United States - 49,500,000
Nigeria - 37,200,000
Kenya - 14,600,000
Tanzania -14,000,000
Bangladesh - 11,900,000
Afghanistan - 11,400,000
Iran - 11,300,000
Canada - 9,700,000
Pakistan - 9,700,000

The Global Audience Measure is an annual update of how many people are consuming the BBC weekly for all services in all countries across all platforms (television, radio, website and social media). Key to this is de-duplication i.e. ensuring that a person who consumes multiple BBC services or platforms or on multiple devices is not counted many times in the top level totals, which means those totals are often not the sums of their constituent parts.

DRM digital radio standard recommended by the South African government

DRM digital radio standard recommended by the South African government

The South African Minister of Communications and Digital Technologies, Stella Tembisa Ndabeni-Abrahams, issued on July 1st 2020 the policy direction regarding the introduction of digital sound broadcasting (DSB) in South Africa which recommends both DRM (for AM and FM bands) and DAB+.  

This is a momentous decision for South Africa, the African continent and also a first for digital audio broadcasting as it brings together the two ITU recommended open digital radio standards, DRM and DAB+.

The directive is based on the regulatory South African acts, the ITU Radio Regulations of 2016, the SADC (LINK) band plans and the Broadcasting Digital Migration Policy. The aim is to provide a licensing framework and optimum allocation of radio frequencies for the South African three-tier system of public, commercial and community broadcasting services. This will stimulate, where economically feasible, the South African industry in the manufacturing of DSB receivers and ancillary gadgets and encourage investment in the broadcasting sector. This is both a positive sign and encouragement to the broadcasting sector to attain the goals for universal service and access to all.

The recommendations are:

DRM Digital Radio Mondiale to complement analogue AM service in the MW band (535.5- 1606.5 kHz), analogue FM services in VHF band-II (87.5-108 MHz); and to be deployed in the allocated VHF band-III (214-230 MHz).

DAB+ transmissions to complement in the allocated VHF band-III (214-230 MHz).

All DRM and DAB configurations of the respective standards to complement the existing analogue sound broadcasting in any other applicable sound broadcasting band within the confines of the prevailing radio frequency plan and consistent with ITU Radio Regulations for Region 1.

Here's the policy document on the introduction of digital sound broadcasting in South Africa :
