A year-long operating event, "Science Milestones in the History of Radio," is under way, sponsored by the Italian Amateur Radio Association (ARI) Fidenza Radio Club[1]. Each month will highlight individuals who laid the foundations - theoretical and practical - for radio science. Awards are available for participating stations.
Each month, a commemorative station with a distinctive call sign will be on the air featuring an individual - some better known than others - with a role in the history of wireless communication. During January, II4MXW is active, honoring the contributions of James Clerk Maxwell.
Commemorative stations on the air for the remainder of 2018 are:
February
II4HRZ
Heinrich Rudolf Hertz
March
II4CAO
Temistocle Calzecchi Onesti Calzecchi (He demonstrated in experiments from 1884 through 1886 thatiron filingscontained in an insulating tube will conduct an electric current under the action of anelectromagnetic wave. This discovery was the operating principle behind the early RF detector known as a "coherer," developed several years later by Oliver Lodge, Edouard Branly, and Guglielmo Marconi.)
April
II4MAR
Guglielmo Marconi
May
II4TES
Nikola Tesla
June
II4AMP
Andre Marie Ampere
July
II4COU
Augustin de Coulomb
August
II4VOL
Alessandro Volta
September
II4LNZ
Heinrich Lenz (Lenz's law states that an induced electromotive force(EMF) always gives rise to a current whose magnetic field opposes the change in original magnetic flux.)
October
II4OER
Hans Christian Oersted
November
II4HNR
Joseph Henry (He studied induced currents and made electromagnets that led to the development of the telegraph. In 1832, simultaneously with Michael Faraday, he discovered the phenomenon of self induction, demonstrating that a magnet moving within a magnetic field produced an electric current.)
December
II4FRD
Michael Faraday
Further details and award rules[2] are available on the ARI-Fidenza website.
