Abstract :
This paper relates to investigations extending from January to August, 1938, (including winter, summer, and rainy seasons) on atmospheric disturbance in medium- and short-wave bands (0.6 to 6 megacycles) prevalent in the eastern part of India. A suggestion has been made for broadcast transmission standards to be adopted in India on the basis of atmospheric field-strength measurements. Effective service areas of 1.5 kilowatts, 370 meters and 5 kilowatts, 235 meters, medium-wave broadcast transmissions have been estimated on the standards suggested.
