130th Anniversary of the Invention of Radio & 100th Anniversary of the IARU
In late summer or early autumn of 1895 (the date is uncertain), Guglielmo Marconi succeeded in transmitting the three dots of the letter "S" in Morse code from Villa
Griffone near Bologna to a receiver located more than a mile away and behind a natural obstacle, the so-called Celestini Hill. This event is considered the beginning
of radio transmissions in the world.
One hundred years ago, amateur radio associations around the world decided to create an organization to represent them. Thus IARU, the International Amateur
Radio Union, was born of which and ARI is the only Italian delegate.
To celebrate both the 130th anniversary of the radio invention and the 100th anniversary of IARU, ARI - Italian Radio Amateurs Association - is announcing an
Amateur Radio Award named "The 130-100 Award," meaning 130 years of radio and 100 years of IARU.
From September 15 to October 15, 2025, many ARI Radio Club stations will be present on the HF amateur radio bands. Look for stations of the ARI Sections with
Special IARU Callsign: i.e. several stations with prefix II or IR + call-area+ IARU (e.g. II1IARU or IR1IARU). See https://www.ari.it/ for more information;
certificates and eQSLs will be available on HamAward.
