Abstract
THE August issue of the Journal of Scientific and Industrial Research published in Delhi contains an article by S. P. Chakravarti entitled “Manufacture of Wireless Apparatus in India”. The growth of radio in India began in 1926, when two low-power broadcasting stations were set up in Bombay and Calcutta. In the following seven years radio telegraph and telephone beam stations were installed linking India with Great Britain and later with Japan. Since 1936, a broadcasting service has been operated on progressive lines under a separate department known as All India Radio. In spite of these developments, however, the production in India of radio equipment, including broadcasting receivers, prior to the outbreak of war in 1939, was confined to the assembly of sets from imported parts and components. In the following years these imports became increasingly difficult to obtain, and many firms had to abandon the manufacture of radio sets. In 1942, a systematic examination of the manufacturing position was carried out by the Government of India in connexion with the development of military radio sets. Investigations leading to the development of certain components from materials available in India have since been carried out under the auspices of the Radio Research Committee of the Board of Scientific and Industrial Research. It is now known that sufficient facilities for the manufacture of all components except valves exist in India, and that the organisations-some twenty in number-possessing manufacturing facilities are in urgent need of special basic materials and appliances.
