Commemorating The Transatlantic Test’s Centennial

In the storied history of amateur radio, few dates are more significant than December 11-13, 1921. That’s when members of the Radio Club of America (RCA) and the American Radio Relay League (ARRL) successfully transmitted Morse code signals that reached from Connecticut to Androssan, Scotland, on 230 meters (1.3 MHz), marking the first time amateur operators had spanned the Atlantic Ocean from the U.S. to Europe. The historic signals were also heard in England; Germany; Puerto Rico; Vancouver, BC; California; and the state of Washington.

Using a transmitter that had an input power of 990 watts and a T cage antenna (100  feet long and 70 feet high with a radial counterpoise), the Transatlantic Test Project proved that the average ham could reach great distances without the need for expensive setups, such as a Marconi wireless system. It fired the imagination of amateur radio inventers who have been experimenting with ways to improve wireless communications for the last century, leading to technologies that couldn’t have been imagined by the amateurs sending dits and dahs from station 1BCG in Greenwich, CT—
