NEW DRM RECEIVER UNVEILED at HFCC MEETING IN MIAMI, FLORIDA THIS WEEK!

The HFCC meeting is being held 22-26 August in Miami and on this occasion there was a live DRM transmission form Radio Vaticana received on  the new Titus2 DRM receiver (pls. see attached document with picture and details) http://www.drmna.info/.

Here is also a little testimony of how this prototype to be sold “at under 100 dollars” performed from Ray Robinson, Operations Manager at KVOH (Voice of Hope / Voz de Esperanza):

I’m currently at the HFCC conference in Miami, and reception of the DRM broadcast here this afternoon was very successful.  Reception was made outside the hotel on two receivers – a  NewStar DR-111 and a brand new pre-production receiver from Pantronix called the Titus 2, with a cluster of attendees gathered round taking photos and videos.  The latter receiver is based on an Android tablet in a stereo radio format with one speaker each side of the central horizontal tablet.  Reception on both radios was solid throughout, on a day when analog reception on 16m was plagued with a lot of atmospheric noise.  We haven’t done detailed calculations, but figure there were probably at least three hops from Italy to Miami, and for a daylight path, the reception quality was nothing short of astounding.

Radio World: The evolution of shortwave radio

Panasonic-RF-2200-1

Many thanks to SWLing Post contributor, Richard Langley, who shares the following article by James Careless in Radio World Magazine.

The article includes interviews with Andy Sennitt, Kim Andrew Elliott, Nigel Fry,  and even yours truly. The following is a short excerpt taken from the introduction of the article:

(Source: Radio World)

OTTAWA, Ontario — With the advent of radio in the 20th century, the shortwave band (1710–30,000 kHz) soon became a hotbed of long-distance radio broadcasting. Used primarily by state-run international broadcasters, plus ham radio operators and ship-to-shore radio communications, the shortwave band was prized due to its astoundingly broad reach.

That reach was — and is still — made possible by the tendency of ground-based shortwave radio transmissions to bounce off the ionosphere and back to earth; allowing shortwave broadcasts to “hop” repeatedly, increasing a broadcast’s range while minimizing its decay.

[…]At the height of the Cold War, the shortwave bands were packed with content as the Voice of America and West Germany’s Deutsche Welle (Voice of Germany) traded ideological punches with Radio Moscow and East Germany’s Radio Berlin International. This is because analog shortwave radio broadcasting was the only way for both sides to make their political cases cross international borders: There was no satellite TV, let alone any internet.

This article is well worth reading and one of the more in-depth pieces I’ve seen in a trade publication or news site recently.

I should add that I completely agree with James Careless’ conclusion:

“[T]he research that went into this article suggests that the shortwave band is sufficiently alive to be still evolving.”

The fact is, the shortwave landscape is not what used to be in the Cold War. Many of those big voices have left the scene and, in the process, left the door open to others.

The shortwaves are a dynamic communications space that continues to evolve.

That’s why I keep listening.

First DRM European Workshop

drmlogoFirst DRM European Workshop “Flexible and Complete Digital Radio for Europe”
asks European Stakeholders to Support and Manufacture DRM and DAB+ Receivers

Following from a very successful General Assembly, the Digital Radio Mondiale (DRM) Consortium, and the German DRM Platform held a most comprehensive European workshop hosted by Fraunhofer IIS in Erlangen, Germany from 6th to 7th April 2016.

This was a first such DRM event aimed at offering solutions to all broadcasters large or small. During their presentations and discussions participants stressed that DRM is the ITU endorsed and internationally adopted standard for the distribution of programmes internationally, nationally and up to local coverage level. DRM can also provide an economic and complementary solution to exactly those coverage scenarios that the established DAB/DAB+ networks in Band-III were never designed for.

Following their deliberations the participants urged all stakeholders of Digital Radio in Europe – including European organisations, regulators, broadcasters and the receiver and automotive industry – to embrace publicly the duality and complementarity of the open DRM and DAB standards as the complete Digital Radio solution for Europe (and worldwide). This means a digital future for all broadcasters, offering more programme choice to listeners, extra multimedia services with text and images, increased energy savings and spectrum efficiency. The participants ask ‘all European stakeholders to promote actively the manufacturing and distribution of multi-standard Digital Radio receivers, comprising at least the DRM and DAB standards.’

The first session, held in conjunction with the open part of the DRM General Assembly, took a brief look at the status of DRM adoption around the world, including the DRM roll-out in India, ready to become the largest digital radio market in the world with over 600 million people being reached by DRM broadcasts. Presentations given by experts from various European countries showed that the digitisation of radio progresses in Europe. At the end of the first day Fraunhofer IIS (Bernd Linz) demonstrated the latest development to provide traffic and travel services in DRM radios, soon to be installed in Asia. Afterwards Martin Speitel demonstrated the features of the Fraunhofer software package for car radios with DRM. With this solution, radio manufacturers can quickly build or enhance radio platforms on a proven modular system covering the full DRM and DAB standards including their full feature sets, thus shortening their development times and, in turn, reducing their costs.

On the 7th April benefits and opportunities of DRM were shown with practical applications. Ampegon (Matthias Stoll) showed how easy and cost-effective the transition from analogue AM to DRM can be. Marc Holthof of the German Navy gave an example of how to use DRM over shortwave for maritime broadcasting of information and entertainment to ship crews at sea. Csaba Szombathy, Technical University of Budapest, demonstrated his original monitoring programme of DRM transmissions. Then RFmondial (Jens Schroeder), demonstrated how to provide DRM services in the crowded FM band compatible with all the existing FM stations. Joachim Lehnert, German DRM Platform Chairman, showed that DRM is a suitable system for local/regional coverage in VHF Band III, fully compatible with DAB/DAB+ and DVB-T networks and in keeping with RRC-06. RFmondial (Detlef Pagel) also referred to the use of DRM in VHF Band III and stressed that DRM+ is the most suitable digital system for the local and regional single-station broadcasters, as a complement to multiplexes, while sharing all the listener related features with the DAB+ standard. Finally, Manfred Kühn, Mobile Broadcast Consult, demonstrated the flexible transmission of multiple DRM channels in a single DAB frequency block in VHF Band III.

This session was followed by a status report on the development of digital multi-standard radios, presented by Robert Bosch Car Multimedia, NXP, Fraunhofer IIS, PnP Networks and Panasonic. All the speakers finally emphasized the market and framework requirements for the production of multistandard radios for Europe.

Joachim Lehnert, Chairman of the German DRM Platform, concluded that the workshop was an important step to bringing national activities together and added; “With all the European DRM activities presented over the past two days and the encouraging messages from the receiver industry, I believe that the famous ‘chicken or egg’ problem can be solved from the receiver end by adding DRM as a complement to existing digital receivers. This will eventually help all radio broadcasters across Europe, whether national, local or community stations, and will ensure each has a digital home in the future.”

Extended HE-AAC: DRM to upgrades audio codec

drmlogoMany thanks to SWLing Post reader, Mike, for sharing this news item on RadioInfo:

(Source: RadioInfo)

The latest upgrade to DRM’s audio codec was demonstrated in a presentation at this week’s Digital Broadcasting Symposium in Kuala Lumpur.  Digital Radio Mondiale (DRM) is the first global broadcast standard to adopt the Extended HE-AAC (xHE-AAC), which promises improved quality for DRM broadcasts in SW, AM and FM.

Alex Zink, the Senior Business Development Manager for Digital Radio at Fraunhofer, outlined the benefits of DRM in emergency situations, particularly the ability of DRM transmissions to signal receivers to turn on automatically and deliver emergency warning messages in a crisis.

“Unlike consuming radio on a smart phone, there is no gatekeeper in between digital free to air broadcasting and the consumer,” said Matthias Stoll in his presentation during the afternoon workshop.[…]
