KOLKATA, India�Today the CEO of Prasar Bharati, the Indian public radio and television organization, Mr. Jawhar Sircar inaugurated the new 200kW medium wave transmitter of All India Radio Kolkata (657 kHz) at Aamtala making AIR Kolkata digital-ready, according toDRM news.
This brings the total of new DRM medium wave transmitters commissioned in India to 21 (out of planned 35).
The previous transmitter was vacuum-tube based, whereas the new one is purely solid-state with higher efficiency, meaning significant electricity savings for AIR. �This transmitter will cover the whole of South Bengal, adjoining regions in the eastern part of India, and part of Bangladesh. The transmitter will start with simulcasts but can be switched to pure DRM very quickly, which will bring extra energy savings.
Engineering Chief of Kolkata, Animesh Chakraborty, said the new digital system would work simultaneously with analog until all the radio sets switched to digital sets in next few years.
