100 years of Trans-Atlantic Communication!

December 11, 2021 marks one hundredth anniversary of the “Transatlantic Test of 1921”, where radio signals sent by American amateur radio operators were first copied by amateurs in Scotland as well as England, Holland, Germany and France.

The first transmissions were only one-way due to transmitter and antenna limitations, and it would be 1923 before successful two-way transmissions were copied.
