3. Which Was The First Radio Station? In 1916 an amateur operator and engineer for Westinghouse Electric began broadcasting programs from his garage on amateur station 8XK in Wilkinsburg, Pennsylvania. The broadcasts were enthusiastically received by other Radio amateurs who liked hearing wireless music. The broadcasts resulted in a newspaper article which generated such interest, that Westinghouse decided to build a station for the purpose of broadcasting.

4. Radios Father So who was the father of Radio? We have credited Marconi traditionally, however there is much doubt that he is the true father of Radio. He was very industrious, highly inventive, and had the strongest and most successful entrepreneurial spirit of any of Radio's fathers. He made excellent commercial applications for wireless telegraphy. However our exhaustive research points to the father of Radio as Nikola Tesla who had disclosed wireless and the technology at a lecture in 1893, preceding Marconi's wireless inventions and practical demonstrations. In fact, a Supreme Court case in 1943 ruled that Tesla was the father of Radio. Marconi's first patent was issued in 1900 and Tesla's in 1898. So who was the father of Radio?

5. Early Radio Devolepment The key invention for the beginning of "wireless transmission of data using the entire frequency spectrum", known as the spark-gap transmitter, has been attributed to various men. Marconi equipped ships with lifesaving wireless communications and established the first transatlantic radio service. Tesla developed means to reliably produce radio frequency electrical currents, publicly demonstrated the principles of radio, and transmitted long distance signals.

6. Theory Of Electromagnetism Several scientists speculated that light might be connected with electricity or magnetism. Around 1830 Francesco Zantedeschi suggested a connection between light, electricity, and magnetism. In 1832 Joseph Henry performed experiments detecting electromagnetic effects over a distance of 200 feet (61 m) and postulated the existence of electromagnetic waves. In 1831, Michael Faraday began a series of experiments in which he discovered electromagnetic induction. The relation was mathematically modelled by Faraday's law, which subsequently became one of the four Maxwell equations. Faraday proposed that electromagnetic forces extended into the empty space around the conductor, but did not complete his work involving that proposal.

8. What is about radio We all know that the oldest radio is difficult to find nowadays. We all know that the oldest radio is difficult to find nowadays. Presently, the oldest radio had been displayed at almost all National Museums. Presently, the oldest radio had been displayed at almost all National Museums.
