DRM receiver module cuts power and costs

DRM is the world’s leading digital radio broadcast standard able to provide rich, high quality digital content over vast areas using medium-wave (MW) and short-wave (SW). In addition to high-capacity local broadcasting at Very High Frequencies (VHF).

The DRM1000 is a complete ‘antenna to speaker’ module, containing all hardware, software, IP and patent licenses required for a radio equipment manufacturer to easily realise a dual mode (digital and analogue) DRM capable receiver.

The module offers a 60% cost reduction and 80% power reduction over existing DRM technologies in the market. The device can run effectively from solar or wind-up rechargeable batteries: in addition to small primary cells.

Low power operation directly improves accessibility to vital educational and public digital radio services across many emerging nations and opens the great features of DRM to many millions of potential listeners around the world.

In offering the DRM1000, CML Micro enable customers to design a complete DRM /AM /FM broadcast receiver solution, which is attractive, highly featured and accessible for all. The module allows these innovative receivers to be manufactured locally in emerging nations in addition to traditional technology manufacturing locations.

In addition to introducing the DRM1000, CML Micro announced that the device has been adopted by Gospell Digital Technology for two new DRM portable radio families to be shown for the first time at the recent IBC 2023 DRM Showcase Event.

Haochun Liu, Head of Research and Development at Gospell, said: “At Gospell, we've always held a steadfast belief in the pivotal role that the accessibility and ubiquity of DRM radios play in enabling people to access high-quality information. This unwavering commitment has driven us over the years to design and manufacture user friendly DRM receivers, constantly pushing the boundaries to make them more accessible and attainable for all. The introduction of the DRM1000 module, with its impressive low-power consumption, cost-effectiveness, and high performance, has been a game-changer. We are truly honoured to collaborate with CML Micro in launching two groundbreaking DRM receivers based on the DRM1000 module, namely the GR-220 and GR-221. We're confident that our combined efforts will not only deliver unparalleled value to people but also pave the way for the next chapter in DRM technology.”

One third of the world’s population remains without an internet connection. Many millions of people will benefit from widespread DRM adoption. Increasing access to DRM enhances public services in remote areas, or where an internet connection is very expensive.

This includes a disaster and early warning service that can be used in the event of interruption to communications caused by natural disasters.

CML Micro’s VP of Global Marketing, Matthew Phillips, said: “The benefits of DRM are already being enjoyed by listeners in the Indian market with 70% of the population covered by DRM broadcast services and 6 million new cars already fitted with DRM capable receivers.  We believe the market for DRM capable receivers is set for significant growth over the coming years. The DRM1000 provides an ideal platform to serve this emerging market with low cost, battery-powered portable receivers sold in millions of units.”

DRM in the medium-wave or short-wave band delivers FM-like quality to listeners spread over many thousands of square miles, from a single transmitter. This makes DRM the optimum digital radio solution for emerging nations. DRM uses existing long-, medium-, short-wave and very-high frequency (LW, MW, SW and VHF) radio frequency bands, operating seamlessly alongside current analogue services.
