SIXTY YEARS OF TRANSATLANTIC RADIO
On December 12, 1901, Guglielmo Marconi at a hastily-erected station on Signal Hill, St. John's, Newfoundland, was successful in detecting Morse signals emanating from Poldhu in Cornwall, 2,200 miles away. The Atlantic Ocean had been bridged by wireless telegraphy - an achievement which leading scientists of the day declared to be impossible.
The picture shows part of the transmitting station which had been
built at Poldhu for the experiment. This station was 100 times more
powerful than any other which had been previously built. On the extreme
left are the transformers. The banks of capacitors can be seen in
the wooden rack. On the extreme right is the spark gap.
