However, the need for communication at sea remained high. Eventually, the novelty of wireless telegraphy waned. The sound of the spark could be heard four miles downwind from the station. This brought little enthusiasm from local residents, who endured the sounds of the crashing spark from the great three-foot rotor supplied with 30,000 watts. The station’s effectiveness was limited however, so broadcasts were made between 10 pm and 2 am when atmospheric conditions were best. The South Wellfleet station became the lead North American facility for this function. Business and social messages could be sent for fifty cents a word. Ocean-going vessels quickly adopted Marconi apparatus to receive news broadcasts, and soon ship-to-shore transmittals were a major operation. With elation, communiques from President Theodore Roosevelt and King Edward VII were translated into international Morse code at the South Wellfleet and English stations, respectively, and were broadcast. Januthe first public two-way wireless communication between Europe and America occurred. The first transatlantic signal from England had been detected. Through that hanging wire he heard the anticipated signal from across the ocean. He sought to prove that radio waves could cross the Atlantic. John’s, Newfoundland, Marconi raised a kite with an antenna dangling from it. Wireless telegraphy was suddenly the rage of Europe – and then of America. By 1901, Marconi achieved a range of 200 miles. At first, Marconi used homemade equipment, testing and repeatedly modifying it, each time stretching to greater limits the distance that signals could be received from a transmitter. In 1894 Marconi retreated to a top floor laboratory of his family’s Villa Grifone near Bologna, Italy, and at the age of twenty began his experiments in earnest. This German physicist first demonstrated the existence of electric and magnetic waves, and with this revelation young Guglielmo Marconi began dreaming of a way to send messages from transmitter to receiver without the aid of wires. The experiments of Heinrich Hertz inspired the idea.
