He has worked in amateur conditions and partly in a secret from his dad. In June 1895, he accomplished a 1st winning – he set up a radio touch with radio receiver which was situated 1 kilometer from him. Unfortunately, he has not noticed any interest in his technology in Italy, so he decided to go to England in March 1896. Here he went to the head engineer of the British Post Office.
On the 27th of July in 1896, the transmission specialized equipment was installed on the top of the Key Post Office in London. The Morse’s printer recipient was put on the top of a building located a kilometer from the post office. Guglielmo managed a telegraph key, and viewers at the printer were able to see the words. This event is known as to be the 1st public experiment of the radio. Afterwards, in 1899 here was an attempt to transmit the signal across the British Channel and in 1901 passed a message across the Atlantic Ocean from Canada to England. The 1st message that was delivered across the Atlantic was the letter “S” of the Morse code.
