Today, India is vibrant with innovative ideas in the field of usage of Information Technology and is keen to see that the fruits of this new technology brings happiness into their life.

FM Radio

 Agriculture Information Dissemination System by FM Radio



 Which Technology is feasible

Rural communities, their institutions, government and other agencies all have well developed communication networks for local information dissemination, and many people still trust word-of-mouth information, and what they can see with their own eyes above other information. A study of farmers in India found that farmers trusted endogenous sources, such as word-of-mouth, experience and observation more than exogenous sources such as extension agents.

Traditional media such as television and radio can reach a wide audience. Radio is more widespread than television in India, and the number of households with a radio has grown rapidly over the last 40 year. But public service broadcasting is collapsing in many countries, and is being replaced by commercial FM channels, which tend to broadcast music and entertainment rather then educational programs. A few commercial channels however retain an educational component and there are many successful community-radio stations funded by bilateral and non-government donors.

Most developing countries are rushing to join the Internet age. India, in particular invested heavily in telecommunications infrastructure over the last decade, and now has Internet connectivity down to District level throughout the country.

Many organizations are incorporating this information within the new information systems through publications and CD ROMs and research studies. A recent CD ROM and Internet-based database contains farmer-based information on 200 crops and 150 countries including images and descriptions of over 1800 pests, diseases and weeds. This is also happening in developing countries. The National Innovations Foundation (NIF) in India has been established to build linkages between excellence in formal scientific systems and informal knowledge systems.

There is great scope for integrating existing communication systems and networks in developing countries into new information systems. The Indian Council for Agricultural Research (ICAR), Indian Agricultural Statistics Research Institute (IASRI) and Department of Information and Publications in Agriculture in India are collaborating to build a nation-wide information network for agricultural research and extension.

About FM Radio Station

A radio station basically records and transmits. It often shares studio facilities, but it owns the transmitter that is its heart. Let us first recall some electronic techniques and then see how an FM station broadcasts, and finally examine project execution. We create sound waves when we speak. We convert them to electrical waves in order to transmit them far. Both waves possess frequency. Suppose a string of sitar vibrates 440 times per second. A microphone turns these vibrations to an electrical signal that also changes 440 times a second. Let us imagine the signal as a moving caterpillar. Its body from one hump to the next is a cycle, and the distance between them a wavelength. Frequency is the number of cycles occurring in one second. We measure it in Hertz (Hz) in memory of the scientist who discovered electric waves.
