Electrical engineering milestone. Transatlantic Radio Signals. At Signal Hill on 12 December 1901 Guglielmo Marconi and his assistant George Kemp confirmed the reception of the first transatlantic radio signals with a telephone receiver and a wire antenna kept aloft by a kite. They heard morse code for the letter "S" transmitted from Poldhc Cornwall. Their experiments showed that radio signals extended far beyond the horizon giving radio a new global dimension for communication in the twentieth century

This stone marks the site of The Needles Wireless Telegraph Station where Guglielmo Marconi and his British collaborators carried out from 6th December 1897 to 26th May 1900 a series of experiments which constituted some of the more important phases of their earlier pioneer work in the development of wireless communication of all kinds.
