Patent
7777-Oscillating
sintonic
circuit
with
inductance
and
capacity -
London
1898.Before,
it was not
only
impossible
to send a
reserved
message,
it was
also
impossible
to install
more than
one radio
station in
the same
place
because
the
transmission
of one
would
interfere
with the
transmissions
of the
other and
it was not
even
possible
to select
the
signals on
reception.
Magnetic

1903.This
detector
was
conceived
by Marconi
in 1902
and used
to receive

Ship CARLO
ALBERTO.
