Abstract

AN outline of the policy and plans of the broadcasting organization known as All India Radio for the erection of broadcasting stations in India was given in a recent issue of the Indian Listener. The two main features of the problem of providing a broadcasting service in India are the relatively large area of country to be covered, and the intense atmospheric interference. It is considered to be desirable to provide as quickly as possible some sort of broadcasting service for the whole area of India, and with this object in view five short-wave transmitting equipments have been ordered and will be located at Delhi (two stations), Bombay, Calcutta and Madras. At the same time, five medium-wave stations have been ordered to provide a first-grade broadcasting service for the towns of Lahore, Luck-now, Trichinopoly, Dacca and Madras. These will supplement the existing medium-wave stations at Delhi, Bombay, Calcutta and Peshawar, so that shortly All-India Radio will have in operation five short-wave and nine medium-wave stations, the aerial power ratings of these varying from 0·25 to 10 kw. Bearing in mind that, in contrast with the practice in other countries, the short-wave stations have to provide an internal service in India, the operating wave-lengths will probably be between 30 and 50 metres for daytime and between 60 and 90 metres for night working. It is considered unlikely that there will be any interference between these stations working an internal service in India, and European and other short-wave stations operating an international service. The new medium-wave stations will operate on wave-lengths between 200 and 400 metres and will have large frequency separation so as to facilitate the provision of simple cheap receivers.
