Building for a Billion

Nautel has completed the installation of 27 MW-AM DRM transmitters and associated equipment ordered in 2013 by India’s Prasar Bharati for All India Radio (AIR). This massive project has the goal of bringing digital radio to nearly a billion residents of India.

The first 27-unit order of eleven 100 kW NX100, ten 200 kW NX200, and six 300 kW NX300 DRM-enabled MW-AM transmitters comprised the world’s largest digital radio deployment to date. A second six-unit follow-up order includes four 100 kW NX100, and two 200 kW NX200 DRM-enabled MW-AM transmitters.

All transmitters are configured for DRM30 transmission. The first set of 27 transmitters are on air throughout India with the second set of six transmitters shipped in July, 2017; click here to see a detailed map.

Working with Nautel on this large-scale deployment was Comcon, Nautel’s in-country partner along with Altronic, provider RF test loads; Digidia, provider of DRM modulators/content servers and Kintronic Labs, who supplied matching systems.
