ARLA/CLUSTER: O primeiro contacto radioamadoristico trans-Atlantico em Onda Curta foi realizado à 95 anos

[João Costa > CT1FBF]

First short wave trans-Atlantic contact made 95 years ago

It was on the night of 27th November 1923 that the first Trans-Atlantic
short wave radio contact was made. It took place between radio hams: Leon
Deloy (8AB) in France and Fred Schnell (U1MO) in the USA.

This first short wave Trans-Atlantic contact represented the culmination of
many tests and attempts to hear and then make contacts across the Atlantic.

The contact pushed forwards the technology used, not only by radio amateurs
but other users as well.

After the First World War, it took some time before British radio amateurs
were allowed back on the air, and as a result of restrictions and for many
other reasons, the equipment available was limited. This forced the use of
improved technology and techniques. That said, the first contact was made
between the USA and France, but Britain also succeeded and went on to make
the first contacts with the Antipodes later.
