All India Radio (AIR), the public service broadcaster in India, has adopted the international DRM (Digital Radio Mondiale) standard for the digital terrestrial radio transmissions in the MW and SW bands. DRM allows for multiple FM-like radio services plus associated data such as multi-lingual news articles to be carried in place of or as an extension to the former analogue radio services, while maintaining the large-area service coverage of the AM bands.
35 MW transmitters of AIR, of power ranging from 20 kW to 1000 kW, continue to operate in DRM – 2 of these in pure DRM and 33 in simulcast. 25 of these are working in pure DRM daily for one hour. 2 SW transmitters are also carrying services on DRM.Two more transmitters, 100 kW each, are under trial in Delhi and these are expected to be operational soon.
