Marconi National Historic Sites of Canada in part, to commemorate Marconi's first transmission tests in 1901. The Marconi National Historic Site of Canada, located at Table Head in Glace Bay, is the site of Guglielmo Marconi's first transatlantic wireless station, callsign VAS, and the first wireless message sent from North America to Europe on December 15, 1902. The site features the remnants of Marconi's transmission towers, a modern amateur radio station, plus a museum chronicling Marconi's achievements. Marconi chose this site for its elevated flat expanse and unobstructed view out over the Atlantic Ocean. Some of the concrete footings for the massive towers can still be
Guglielmo Marconi day during which the entire transatlantic path was in daylight. It is now known (although Marconi did not know then) that this was the worst possible choice. At this medium wavelength, long-distance transmission in the daytime is not possible because of heavy absorption of the skywave in the ionosphere. It was not a blind test; Marconi knew in advance to listen for a repetitive signal of three clicks, signifying the Morse code letter "S". The clicks were reported to have been heard faintly and sporadically. There was no independent confirmation of the reported reception, and the transmissions were difficult to
