NEW DELHI: Production facilities are being digitised at 98 centres to further enhance the reach of medium wave band transmissions of All India Radio.

AIR sources told indiantelevision.com that despite the growth of FM Radio, medium wave is being received by 98.41 per cent of the population and 90.63 per cent of the area.

The MW transmissions are being provided through 146 MW transmitters of various capacities, according to AIR sources.

A survey by AIR in 2010-11 had also found that respondents in both rural and urban areas had rated the reception quality of AIR?s Primary channel and Vividh Bharati as satisfactory.

In an effort to improve the transmission, the sources said that 17 transmitters had recently been replaced by Digital Compatible transmitters.

In addition, several new schemes are under implementation under the 11th Plan. These include installation of new transmitters at two places, replacement of old transmitters by new Digital Transmitters at 31 places, upgradation of old transmitters by new Digital transmitters at five places, digitisation of existing compatible transmitters at 36 places, and digitisation of connectivity and linkage at all places. AIR is planning to continue digitisation under the 12th and future Plans.
