THE 100TH ANNIVERSARY OF MARCONI'S HISTORIC TRANS-ATLANTIC RADIO TRANSMISSION December 12 2001

 The Marconi Radio Club and The Falmouth Amateur Radio Association Amateur Radio operators are making plans to celebrate a Marconi world historical event. December 12, 2001 will mark the 100th anniversary of the first Trans-Atlantic radio transmission. That signal was transmitted across the Atlantic from Poldhu, Cornwall England to St John's, Newfoundland. Radio pioneer, Marconi, sat listening at Cabot Tower on Signal Hill in Newfoundland. His antenna dangled from a kite in the sky, and through that hanging wire, he heard the anticipated signal from across the ocean, "dit dit dit". The letter, "S", in Morse code. Marconi, son of an Irish mother and an Italian father, had been playing with electricity since he was a child. A rebellious student, he hated lessons but loved to experiment and invent. By the time he was nineteen, he had resolved to be the first man to give the world a system of communication based on electromagnetic waves. By trial and error, relying on his own intuition and audacity, Marconi conducted a series of experiments indicating that long-distance wireless communication was possible. His goal was accomplished and crossed the world over the threshold of radio as we know it today.

HISTORIC COAST RADIO STATION WILL CELEBRATE MARCONI EVENT

Stations KPH and K6KPH will be on the air on 12 December 2001 to help celebrate the 100th anniversary of the first wireless signal to cross the Atlantic, received by Marconi on 12 December 1901 at St. John's Newfoundland. Both stations will use the original transmitters, receivers and antennas of famous ex-RCA coast station KPH. The transmitters are located at the transmitting station founded by the American Marconi Co. in 1913 at Bolinas, CA. The receivers and operators will be at the KPH receiving station about 20 miles north at Pt. Reyes, CA. KPH will be active on commercial frequencies 500 and 425kc with most activity taking place on 500kc (600m). Power output will be 4.3kW. The antenna is a Marconi T. These frequencies have been made available through the generous cooperation of Globe Wireless, current holders of the KPH license. K6KPH will be active on amateur frequencies 3545, 7050 and 14050kc. Power output will be 1.5kW. Antennas will be double extended Zepps on 3.5 and 7Mc, H over 2 on 14Mc. K6KPH will begin operations at 1700Z (0900PST). KPH will begin operations at 0000Z (1700PST) 13 December 2001Z Commercial practices and procedures will be used on all frequencies to give amateurs the experience of working a real coast station. Traffic lists will be sent and messages for stations that have worked us in the past and sent reception reports will be awaiting in the message rack. All operators will be ex-commercial ops from KPH, KFS and other coast stations.

Amateurs and shortwave listeners are invited to contact or monitor KPH and K6KPH. Maritime stations may call KPH on 500kc.

KPH reception reports may be sent to: Tom Horsfall 1862 Tulare Ave. Richmond, CA 94805, USA K6KPH reception reports may be sent to: Dick Dillman 435 Utah St., No. 4 San Francisco, CA 94110, USA

Marconi new that the veracity of his claims would be challenged. So a few weeks after the first test, he put his equipment aboard a U.S. Naval ship and conducted his experiments again at a range of about 1500 miles or so. This time he did not use headphones. He used a relay and Morse inking register. The experiments were witnessed by Naval officers and the register tapes were signed by the captain of the ship. When they landed in New York harbor, he handed the register tapes to the press with a comment I don't recall at the moment.
