KUWAIT, March 8 (KUNA) — Minister of Information Mohammad Al-Jabri on Thursday opened a project updating shortwave transmitters from analogue to digital radio mondiale (DRM) broadcasting systems, at Kabd radio station.

This is a new achievement for the ministry to be added to a series of vital projects that aim to keep pace with the rapid technical progress around the globe, Al-Jabri told KUNA and the Kuwait TV.

Kabd station, through the new DRM system, will allow “Kuwait’s voice” to reach the entire Middle East region, Europe and Asia, he noted.

Kuwaitis have planned and supervised the project, the minister said, noting that updating the infrastructure of radio stations aims to cope with latest digital broadcasting development, the minister said.

Al-Jabri praised officials, and all the personnel at the ministry’s Engineering Affairs Sector, for their hard sincere efforts.

October DRM Consortium news

Many thanks to SWLing Post contributor, Ed, who shares the following news from the DRM Consortium via their newsletter:

Digital Radio Mondiale: Audio Codec xHE-AAC at No Additional Cost
to Boost DRM Receiver Industry

Via Licensing Corporation, a global intellectual property solutions
provider, announced that the highly efficient MPEG xHE-AAC audio codec
(Extended High Efficiency AAC) will become a default feature of the
popular Advanced Audio Coding (AAC) patent pool. The move to include
the XHE-AAC audio codec into the current patent pool at no extra cost,
is a move that could boost DRM receiver manufacturing. Read more.

benefits to be realised if Governments and manufacturers were to fully
exploit the emergency warning feature embedded in DRM and digital
radio technology. Read more.

Digital Radio Mondiale Delivers at IBC 2017

Participants in the four DRM events organised at IBC by Gospell, Thomson Broadcast, Nautel and Ampegon between 15th-17th of September have had an insight into a wide range of DRM activities, from big projects in Morocco (Thomson Broadcast), India and Hungary (Nautel), to the progress of DRM in South Africa. And DRM used not just for broadcasting but for other vital activities was demonstrated by Rfmondial involved in a wide-ranging application for the US Coast Guard.

One constant for all events, each unique and so different from the other, was the positive messages about DRM in both AM and VHF and the increasing availability of new receiver and receiver solutions, many always on display. The first event on Friday the 15th (Gospell) saw the launch of GR-227 the multi-standard (DRM/DAB/DAB+) car adaptor that is compatible with any car stereo with USB port and able to work with Android Smart Tune App. As the manufacturer explained, this after-market solution can be a significant development allowing digital reception in cars initially fitted with analogue receivers.

Of equal major interest was also the Titus II multi-standard digital radio receiver produced by Titus SDR, a division of PantronX. The consumer software-defined radio digital receiver platform, which is the result of collaboration between Titus SDR/Patron X, Jasmin-Infotech, TWR, and Fraunhofer IIS, supports multi-standard radio reception, including DRM, DAB and DAB+ and core data applications. The representatives of PantronX and TWR received lots of questions about this receiver system based on a custom Android tablet platform, featuring multipoint touch, WiFi/Bluetooth and stereo sound.

Other receiver possibilities: the tablet solution presented by Fraunhofer IIS, the Indian receiver Avion, and a new concept DRM receiver produced in South Africa all enforced the idea that the excellent work done by transmitter companies like Thomson Broadcast, Nautel and Ampegon in providing a digital transmitter infrastructure in many parts of the world can link now with the innovative receiver solutions.

The Thomson event came alive with the presentation about the huge project in Morocco and the Nautel event attracted lots of guests already familiar with the big projects of this established transmitter manufacturer recently in India and now in Hungary.

The last of the DRM events, hosted on the 17th by Ampegon was a moment of celebration. First of this company (now 75 years old) displaying solid-state transmitters of all capacities successfully used globally, as well. As Ampegon has been also involved in Africa and supported the first DRM trial in South Africa two years ago, they were the natural hosts of a special DRM award moment. The DRM Enterprise Award 2017 (Africa) has been awarded to 3 pioneering experts in promoting DRM digital radio in South Africa. The winners are Dr Roelf Petersen on behalf of Radio Pulpit (member of the Pulpit Media Group) and Broadcom International involved in the trial of DRM in mediumwave. The other two winners Thembeka Khaka (Thembeka Khaka and Associates) and Johannes von Weyssenhoff have been very active in getting the legal framework and conducting the current trial (DRM for local coverage) that is taking place in conjunction with a community station in Johannesburg. (This event was streamed on Twitter click here to view.)

As Ruxandra Obreja, Consortium Chairman, remarked: ”All those who have hosted successful DRM events, the new and old supporters and specialists interested in digital radio and DRM, all the other companies supporting DRM and present at IBC (BBC, Babcock, Becil, RFI, Riz, NXP, Rfmondial, Sentech, to mention just a few) all the guests from countries as far apart as India, Argentina, the Netherlands, Belgium, Pakistan, the Philippines have seen how much effort goes so that DRM can deliver for all, globally.”

The GR-227: Gospell introduces a new SDR digital radio car adaptor

Many thanks to SWLing Post contributors Ed and Richard Langley for sharing information about the latest receiver from Gospell: the GR-227 digital radio car adaptor.

According to Radio World:

[…]The compact GR-227 can be added to car stereos, via a USB cable, in order to receive digital radio programs and corresponding data. Based on software-defined radio technology and using the xHE-AAC audio codec, the GR-227 is compatible with both modes of the Digital Radio Mondiale standard as well as the DAB/DAB+ digital radio standards.

According to Gospell, the GR-227 works with car stereos that are fitted with a USB port. Using the firm’s patent-pending technology, the adaptor behaves like a thumb drive when plugged into a USB port, making it compatible with most in-car receivers.

In addition, the GR-227 also features the Gospell Smart Tune App for Android. When partnered with an Android-powered car stereo, this lets users play back the broadcast audio program or benefit from data services.[…]

Read the full article at Radio World.

Richard comments:

“They call it an adaptor but perhaps it’s just an Android-controlled SDR receiver supplying audio output via a USB port, which could be connected to a computer or any other audio device with a USB audio input capability.”

I think he may be correct in that assumption because it may be the only way to get cross-manufacturer compatibility in a device like this.

The product information sheet noted that the receiver is supplied with a “triple band active antenna.” No doubt, the GR-227 will require adding a small external antenna to your car.

Still: an interesting product for sure! Perhaps the price point will be more reasonable that of previous DRM receivers? We’ll post updates from Gospell with the tag: GR-227
