History of radio upon the idea of grounding his transmitter and receiver. With these improvements the system was capable of transmitting signals up to and over hills. Marconi's experimental apparatus proved to be the first engineering-complete, commercially successful radio transmission system. Marconi's apparatus is also credited with saving the 700 people who survived the tragic "Titanic" disaster. In 1896, Marconi was awarded British patent 12039, "Improvements in transmitting electrical impulses and signals and in apparatus there-for", the first patent ever issued for a Hertzian wave (radio wave) base wireless telegraphic system. In 1897, he established a radio station on the Isle of Wight,
Portishead Radio Portishead Radio Portishead Radio (callsign GKA) was a radio station in England that provided worldwide s and long-range aeronautical communications from 1928 until 2000. It was the world's largest and busiest radiotelephony station. In 1974, the station employed 154 radio operators who handled over 20 million words per year. The station's control centre, which was based at Highbridge, Somerset, near Burnham-on-Sea, opened in July 1928. It was constructed by Marconi Wireless Telegraph Company and operated by the General Post Office (GPO). The main transmitting station, which was remotely operated, originally consisted of a large array of radio masts at nearby
