AIR Pushes Toward 2017 Date With DRM

A pair of 1 megawatt transmitters are ordered

At the recent BES Expo 2010 in New Delhi, All India Radio outlined its “Road to Digitization” and confirmed an order for two 1 megawatt DRM-capable medium-wave transmitters.

AIR is aiming for a 2017 digitization of its operations, including digitization of studios and studio-transmitter links, as well as of transmissions using DRM and DRM+ technologies.

The two new transmitters will replace aging analog megawatt medium-wave transmitters in Chinsurah, West Bengal, and Rajkot, Gujarat. Broadcast Engineering Consultants India Ltd. (BECIL) is handling the installation, according to tender award documents posted by All India Radio.

Alokesh Gupta reports on his RadioActivity blog that the transmitters in question are Thomson S7HP units.

According to the DRM Consortium, AIR is already broadcasting in DRM from a high-power shortwave transmitter at Khampur near Delhi.

During the BES Expo, AIR conducted DRM multicast demonstration broadcasts, airing two different services on 6100 kHz simultaneously.

AIR is aiming to have 76 medium-wave, nine shortwave and 64 FM transmitters digitized by 2013, with the remaining transmitters in its network digitized by 2017.
