The Cartagena Team group will be active from May 28 to June 6 using the callsign AM5IP with a special QSL commemorating the 170th anniversary of the birth of Isaac Peral (Cartagena, June 1, 1851-Berlin, May 22, 1895), who was a Spanish scientist, sailor and military man, lieutenant in the Navy and inventor of the first torpedo submarine, known as the Peral submarine.
He had an intense career in the Spanish Navy, intervening in the Ten Years’ War in Cuba and in the Third Carlist War, for which he was congratulated and decorated. He also excelled in scientific work and missions: he wrote a “practical theoretical treatise on hurricanes”, he worked on the lifting of the plans for the Simanalés canal (Philippines) and in 1883 he took over the chair of Physics-Mathematics at the School of Expansion of Studies of the Navy.
