Overview

High Quality Content by WIKIPEDIA articles! The Grupo Radio Ourense is a network of radio stations in Spain. The enterprise began in 1932 with a 100-watt transmitter in Ourense, set up by Ramon Puga Noguerol. Noguerol utilized the radio station primarily to promote the record albums for sale in his commercial store. It was more of a hobby than a business. But, three years later in 1935, the station was granted a formal license, EAJ-57, and the business became more serious. In 1966, the station became a part of a wider commercial association, La Voz del Mino. Pedro Arcas succeeded Ramon Puga at the helm. Radio is the transmission of signals by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. Information is carried by systematically changing (modulating) some property of the radiated waves, such as amplitude, frequency, phase, or pulse width. When radio waves pass an electrical conductor, the oscillating fields induce an alternating current in the conductor.
