A Streamlined Approach to DRM Receiver Design

Software defined radio turns digital radio reception into an application
ALEXANDER ZINK AND MARTIN SPEITEL

Software Defined Radio (SDR) turns the hardwired, task-specific and very elaborate chip development of the past into a flexible software-based design running on a generic, efficient and mass-produced hardware platform. It is not a new concept, but it is becoming a reality in more and more technical systems. Digital radio receivers are one major example for SDR technology, because modern processor platforms offer enough computing power to build almost the complete radio functionality in software.

Digital Radio Mondiale General Assembly 2018 at Spain succesfully concluded


Under the banner "Digital Radio Mondiale Drives Forward", the 2018 General Assembly of the DRM Consortium took place on Tuesday 17th and Wednesday 18th of April, at the Palma Bellver Bay MeliĆ” Hotel on Mallorca hosted by Bosch and RFmondial.

The General Assembly set the strategy and working plan for the next year for DRM. This year's Assembly also elected the Chair and the main bodies of this not-for-profit organisation.  The only additions to the existing Steering Board are Nautel and RRI (Indonesian public broadcaster).   The other Board members are: Ampegon, BBC, Babcock International, Fraunhofer IIS, NXP, RFmondial and Thomson Broadcast.  Thomson Broadcast also joined the Executive Board and Ruxandra Obreja was re-elected Chair of the Consortium.

The busy and friendly meeting was an excellent opportunity for members and guests from Asia, Africa and Europe to review all the activities of the past year, receive updates from country representatives and specialists from all the corners of the globe on an outstanding year of progress for DRM.   On both days they enjoyed direct live transmissions in DRM shortwave from the UK and Bulgaria on receivers like Avion, Gospell and Titus SDR.  A special receiver session was held before the conclusion of this successful event.

For Ruxandra Obreja, DRM Chairman, this was a moment to take stock "and review the excellent progress made by DRM in India and other countries in the Asia-Pacific region, as well as South Africa, other countries in Africa, Middle East and Europe and in the automotive industry. DRM as a flexible and economical provider of audio and extra benefits like emergency warning functionality is now in a unique position to give users a powerful, all-band solution for local, regional, national and international coverage. The General Assembly gave everyone  a reason to be proud but also to step up  the efforts of getting DRM transmissions and receivers in the market."

Listen to the special DRM transmission of BBC World Service content relayed by Babcock International was recorded on the DRM Gospell receiver and the Titus SDR including Journaline

World Amateur Radio Day

Every April 18, radio amateurs worldwide take to the airwaves in celebration of World Amateur Radio Day. It was on this day in 1925 that the International Amateur Radio Union was formed in Paris.

Amateur Radio experimenters were the first to discover that the short wave spectrum — far from being a wasteland — could support worldwide propagation. In the rush to use these shorter wavelengths, Amateur Radio was "in grave danger of being pushed aside," the IARU's history has noted. Amateur Radio pioneers met in Paris in 1925 and created the IARU to support Amateur Radio worldwide.

Just two years later, at the International Radiotelegraph Conference, Amateur Radio gained the allocations still recognized today — 160, 80, 40, 20, and 10 meters.  Since its founding, the IARU has worked tirelessly to defend and expand the frequency allocations for Amateur Radio. Thanks to the support of enlightened administrations in every part of the globe, radio amateurs are now able to experiment and communicate in frequency bands strategically located throughout the radio spectrum.  From the 25 countries that formed the IARU in 1925, the IARU has grown to include 160 member-societies in three regions. IARU Region 1 includes Europe, Africa, the Middle East, and Northern Asia. Region 2 covers the Americas, and Region 3 is comprised of Australia, New Zealand, the Pacific island nations, and most of Asia. The International Telecommunication Union (ITU) has recognized the IARU as representing the interests of Amateur Radio.

Today, Amateur Radio is more popular than ever, with more than 3,000,000 licensed operators!

World Amateur Radio Day is the day when IARU Member-Societies can show our capabilities to the public and enjoy global friendship with other Amateurs worldwide.

April 18 is the day for all of Amateur Radio to celebrate and tell the world about the science we can help teach, the community service we can provide and the fun we have.

We hope you will join in the fun and education that is World Amateur Radio Day!

DRM Drives forward with big successes in the automotive industry. Continuous work goes on to provide ingenious standalone and car receivers. DRM as a provider of more than audio and especially emergency warning functionality puts it in a unique position giving users a powerful, all-band solution they can use for their specific needs and coverage at local, regional, national and international level."
