Building for a Billion

The largest digital broadcasting system in the world has expanded to 33 sites; all using Nautel high-power NX Series transmitters. This massive project by India’s Prasar Bharati for All India Radio has the goal of bringing digital radio to nearly a billion residents of the country.

The first 27-unit order in 2013 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 in 2017 included 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 of all 33 sites with power levels and frequencies.

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.
