DRM Receiver Developments

Excerpt from the report on HFCC A11 meeting at Prague .....

During the closing plenary, Ludo Maes of the DRM Consortium and TDP gave an update on DRM receivers. He mentioned the receivers that are currently available, including the Himilaya DRM 2009 for 199 euros, the Morphy Richards DRM 27024 which has been discontinued but is still available online for 99 euros, the Technisat MultyRadio which is also discontinued but available for 149 euros, and the Uniwave Di-Wave 100 which has had production delayed several times but which may be available by May 2011 for 249 euros. A Starwaves car radio add-on is available for 249 euros, and the professional use Fraunhaufer DRM 30 receivers are readily available. Ludo said at least 10 companies sell DRM receivers - most of them in Germany, but also a few in Australia, the U.K., the Netherlands and the United States.

"The tendency," said Ludo, "is to develop more software-defined radios." These include the HCJB Pappradio, which connects to a computer and costs about 60 to 65 euros; and Ten-Tec, Winradio and other SDR's. 

The DRM Consortium set up a receiver task force, which in October of 2010 visited chipset manufacturers in China and Hong Kong. Ludo said they showed a big interest in DRM, and some have committed to developing DRM receivers. The task force made similar visits to India, where All India Radio plans to broadcast in DRM. 

The receivers will be built in India and China. Ludo explained that new receivers will be on the market soon, including the Himalaya 2008 and the Sarapulsky car radio, both of which will use a chipset from Analog Devices. 

Ludo Maes showed a slide of a prototype DRM receiver for use in India which was to be presented the following week at the Radio Asia Conference. A new Chinese radio called the DR111 was also to be introduced at this conference, and live DRM transmission demonstrations were to be conducted. All India Radio was scheduled to be present, as well as manufacturers of cars and car radios in India. 

In Korea, new DRM 30 and DRM Plus USB receivers are being developed. "Chipset developments will mean a big reduction in receiver prices," according to Ludo. He said chipsets will eventually cost less than one U.S. dollar. By September to November of 2011, when AIR launches its DRM services, Ludo said that two-chipset DRM receivers should be available for around 50 to 60 dollars. And by 2012, he said single-chipset receivers should cost around 15 dollars.
