22 Sep A New Era Begins for Brazilian Radio Broadcasting
A new era begins for Brazilian radio broadcasting with the arrival and installation of a first shortwave digital radio DRM transmitter developed and manufactured in the city of Porto Alegre by BT Transmitters. The transmitter will be sited at the public broadcaster (EBC) Rodeador Park, near the capital Brasilia, to be connected to one of the huge HF antennas of EBC (National Amazon Radio is transmitted from there).
The equipment (a transmitter of 2.5 kW) will be tested on an experimental and scientific basis with the help of the University of Brasilia (UnB) and the Ministry of Science, Technology and Innovation.
The National Radio of the Amazon broadcasts from Brasilia especially to the Northern, Amazonian region of Brazil. The signal will be also available in the neighbouring countries to the north of Brazil. This is primarily a domestic shortwave digital project aimed at the Amazon where about 7 million riverside and indigenous people live. They are far from any other means of communication as there is no mobile phone or internet coverage.
Rafael Diniz, the Chair of the DRM Brazilian Platform, thinks that: “Shortwave digital radio (DRM) for the Amazon region will ensure a new level of communication and information as Nacional’s programming is both popular and educational. It brings audio and much more at low energy cost to whole communities there. With the adoption of digital radio, one of the major problems, that of poor sound quality affecting at times shortwave, will end. Listeners will be able to enjoy DRM broadcasts in short wave with a quality similar to that of a local FM station together with textual and visual multimedia content.”
“This is a huge step forward, says Ruxandra Obreja, DRM Consortium Chair, “not just for Brazil but for the whole of Latin America. When everything else fails or does not exist, DRM will provide information, education, emergency warning and entertainment at reduced energy costs.”

Po przerwie spowodowanej epidemią Indie wracają do rozwoju DRM-u na falach średnich:
"29 Sep All India Radio (AIR) to Expand DRM Digital Radio Services
After the disruption caused by the pandemic, All India Radio (AIR) decided not only to restart transmissions in pure digital mode but also to expand DRM MW digital Radio services.
According to a recent decision of AIR, the stations with single DRM MW transmitters are to carry two digital audio channels in simulcast mode and three audio channels in pure digital mode with Journaline. Timings of the pure digital mode are likely to be announced shortly. In the meantime all the DRM MW stations have been asked to carry out test transmission immediately, to ensure readiness and sustainability of the transmitters for regular transmission of DRM in pure and simulcast modes. This will be an opportunity to carry out field survey . In simulcast mode two digital audio channels and one Journaline (if feasible) is to be tested. In pure digital mode, three audio channels will be available with one Journaline (if feasible). Whether in simulcast or pure DRM the first channel will be News 24×7. In pure DRM the third channel will be the popular Vividh Bharati music programme.
It has further been decided that five major stations (Delhi, Mumbai, Chennai, Kolkata and Rajkot), which have 2 MW DRM transmitters each, will operate one of these transmitters in pure Digital mode throughout the day.
Six more stations (Hyderabad, Vishakhapatnam, Jagdalpur, Bhawanipatna, Sambalpur and Jeypore), which have digital ready MW transmitters, have also been asked to test these transmitters for DRM digital transmissions. Infact test transmission in DRM has already started from Hyderabad and Vishakhapatnam is almost ready."

Taka ciekawostka:
"02 Dec DRM Shortwave Transmissions Relaunched in Hungary
On the occasion of the 95th anniversary of radio broadcasting in Hungary, the Budapest University of Technology has re-launched on 1st December the Digital Radio Mondiale (DRM) shortwave transmissions, currently the only digital radio broadcasts in the country. Their prime objective is to demonstrate the technological capabilities and benefits of DRM digital radio to a wide circle of stakeholders.
The DRM shortwave transmissions in Hungary’s capital have improved once the transmitter was moved to a more suitable, elevated site in Budapest (Janos Hill). At the same there was an important technical upgrade. This improvement is the result of the installation of a new ContentServer. This was provided by Fraunhofer IIS in Germany and their staff gave professional assistance during its installation. The transmissions have now excellent audio quality as the latest audio codec xHE-AAC is now being used. The programmes also benefit from the advanced text feature of DRM called Journaline. This can present on radio screens text in various languages, if needed, as well as graphics and pictures.
Some technical details about these shortwave transmissions:
Frequency: 26.06 MHz
Parameters: Bandwidth = 10 kHz, Mode A, interleaving depth 400 ms, FAC and SDC constellation: QPSK, MSC constellation: 64 QAM
Transmission power: 50 W, which will be increased to 100 W in a few weeks’ time
The primary target coverage area is Hungary’s capital city, Budapest."
