Transatlantic tests - 99th anniversary

On December 11, 1921, radio history was made when the signal from amateur
station 1BCG in Greenwich, Connecticut was heard in Ardrossan, Scotland,
marking the first successful transmission of any radio signal across the
Atlantic using short wave frequencies.

The event, known as the *Transatlantic Tests*, was organized by the ARRL to
prove that short wavelength frequencies could propagate long distances
using transmitters running less than 1kW. Paul Godley (2ZE), considered the
best of operators, was sent to Europe to listen for the participating
stations. His nine tube receiver used the latest superhetrodyne technology
which he modified for these frequencies. On his ocean journey to England,
Godley coincidentally met Harold Beverage who convinced him to use a
specially designed 1300' antenna, referred during that event as the highly
sensitive and directional "Beverage Antenna".

During a pre-event dinner arranged for him by his British hosts, Godley met
Guglielmo Marconi, founder of radio, who asked him to remind the U.S.
amateurs that "I, too, am but an amateur".

Over the course of the test period, more than two dozen stations were
heard, both utilizing spark and vacuum tube CW, but the one that was
received the most consistently was operated by six members of the Radio
Club Of America: Ernest Amy (2VK), Edwin Armstrong, George Burghard (2SS),
Minton Cronkhite (1BCG), John Grinan (NJ2PZ), and Walker Inman (2BGM).
Their station, 1BCG, sent the following, recorded as the first ever
transatlantic message sent on short wave at 2152 GMT on December 11, 1921:

"No.1 de 1BCG. W-12 (Words 12), New York, Date 11/12-21, To Paul Godley,
Ardrossan, Scotland, Hearty Congratulations, Burghard, Inman, Grinan,
Armstrong, Amy, Cronkhite"
