The inventor of the Radio


The inventor of the radio. Was Guillermo Marconi (1.874 - 1.937).
He was a great inventor of the radio or exactly..the Radiotelegraphy.
The Telegraph was invented in polonia in 1896
that was more than 100 years ago.
When he was using a property of the Electromagnetic radio waves or he took an apparatus of his invention and sent a signals at a distance of 2.5 km in Italia.
In that year continued with his experiments in England.
He got signals 12 km.away and, in 1897,he got the link through the Bristol Channel between Penarth and Weston, 20 km away.
On December 15 1902, Guglielmo Marconi transmitted a message from a newspaper on the island of Cape Breton from Table Head in Glace Bay, Nova Scotia (Canada) Poldhu to (England), this being the first message sent across Atlantic.
On January 18, 1903,he transmited a message from the President of the United States, Theoodore Roosevelt, to the King Edward VII of England.
And this was the first menssage transmitted between United States and England.

The radio saved people in cases of natural disasters such as earthquakes, floods and the like, with the prominent participation of Amateur Radio. Nor can we forget the many lives that the radio has saved at the sea.
