In 1919 Guglielmo Marconi bought the ship "ROVENSKA",800 t.,and called it "ELETTRA" which became his navigating laboratory. He made important researches and experiments, such as the first studies on microwaves, on radio-waves propagation, on solar activity and so on. In 1937, when he realized his health was precarious, became afraid of the destiny of his ship. Mister M.Marzari in his article, " La nave dei miracoli " ( The ship of miracles ), wrote everything about the story and the end of the ship "ELETTRA". It’s interesting, sometimes attracting, but it makes everybody think.

The first
concession was given on December 1924 for a period of 6 years to the society U.R.I. (Unione Radiofonica Italiana). It was immediately necessary to
have a new adjustment of rules and laws. In 1928 a second concession for a period of 25 years was
given the society named itself E.I.A.R. (Ente Italiano Audizioni Radiofoniche)
and had to renovate all the installations and update all the programs. Since 1932 the signal of pause between programs has been the twittering of a bird. In the photo you can see the mechanism which generated the sound, used later also by R.A.I. (Radio Audizioni Italia), now Italian Radio television. |

On the left. Marconi Tower ( Sestri Levante) is presently the home of the local Club of the A.R.I. On this tower, to leave from 1930, G. Marconi made to install the station, from he planned and visible in the photo to right, said FARO MARCONI (beacon). Identical station was installed also to S. Margherita Ligure. The scientist had planned also a system of radio guidance to edge of the Elettra and, with the darkened wheelhouse, he gave test of as it was possible to be annoying and to enter in port with the only help of the radio beacons. The length of wave was of 63 cm. |

The cabinet with microwave rtx equipment conceived by G. Marconi and assembled in Rapallo,used,december 1934,for trasmission experiments between Montallegro (Rapallo) to Monte Nero (Livorno). |
A submarine of Regia Marina Italiana (Royal
Italian Navy) was entitled to Guglielmo Marconi.
This submarine disappeared during a mission in
the 2nd mondial war in October 1941.
The ship (see photo) was named Guglielmo Marconi
in honour of the previous submarine.
In 1960 the study on an atomic submarine started
in Italy, but, after the decision of Italy to
discard nuclear devices, the project stopped.
In every case the atomic submarine would have
been entitled to Guglielmo Marconi.

Under. The QSL of a QSO on 40 m. with the submarine off the port of Taranto.

When I look at the Moon, I think that the man landed and walked there and I realize that such a
venture would have never been in any mind without the radio. (Mimma)
Neil Armstrong, after he walked first on the moon, said "For a man this is a small step, but for
the humanity it’s a gigantic one". Guglielmo Marconi, hearing the legendary gun shot, could have
said the same words. (Ubaldo)
