HACKETT'S COVE, NOVA SCOTIA – Nautel has completed the manufacturing phase of transmitters for a large digital radio deployment in India. 27 DRM30-equipped medium wave AM transmitters and associated equipment were ordered in 2013 by India''s Prasar Bharati for All India Radio. All transmitters have been shipped and installation/commissioning is underway, according to Nautel. The first site, AIR''s flagship installation in Delhi, went on-air on May 30, 2014.
Dubbed “Building to a Billion,” the project aims to bring digital radio to nearly a billion residents in the country of India. All India Radio currently serves the entire country via an analog broadcasting service. The transition to digital broadcasting allows AIR to use alternate platforms, and will enable a 24-hour news channel along with other programming. Additional services such as Interactive Text Transmission and disaster warning are also planned.
Transmission sites are located throughout the country. Eleven Nautel NX100 (100kW), ten NX200 (200kW) and six NX300 (300kW) DRM-equipped transmitters were ordered for the project. Nautel NX Series MW transmitters were first introduced in 2007. The NX series transmitters are 90% efficient, occupy a smaller footprint than comparable transmitters, and feature AM precorrection with high linearity, and Nautel's Advanced User Interface.
The current phase of the project will soon place three NX300 sites on-air at Jammu, Jalandhar and Lucknow, along with an NX100 system at Panaji. Nautel is also providing project management services for the installations. Working with Nautel on the deployment is Comcon; Nautel''s in-country partner in India. Altronic is providing RF test loads, Digidia is providing DRM modulators along with content servers, and Kintronic Labs is supplying matching networks for the project.
