 A radioamateur is an individual that devots himself to the development of radioelectric science asking no money in return. His main purpose is to comunicate with his collegues, from all over the world, using equipment, like transmitters and receivers, sometimes home-made. |
What he does is close connected to the technical scientific development of radiocomunications. The radioamateur is always on the vanguard of the technical progress. Many of his projects have contributed decisively to the development of that science. Each radioamateur station is a small independent laboratory,where informations are coordenated for their correlation and anilysis. Also important is that some groups of north-american radioamateurs have successfuly contributed on the launch and situation in orbit of sattelites. |
Untill the end of the nineteenth century all comunications were made by visual means (smoke and flags). In 1833 Gauss and Weber estabilished the first phone line. In 1855 Hyghes invented the telegraph. In1857 Morse created a signal sistem, that is universaly knoun nowdays as Morse code. In 1887 Hertz prooved the existence of electromagnetic waves wich, Marconi perfected. At the begining of this century Bell invented the telephone and Hyghes the microphone. In 1921, appeared the first "Brainys" that studied the electromagnetic waves and discovered the short waves. To these "Brainys" it was given the name of radioamateurs. So, it were the radioamateurs that have astonishly contributed in the 1920/30 decade to the development of comunications, on short waves, that they have discovered. |
The utility of radioamateurs is so big and it has been put in so much evidence, that they have the public gratefulness, for their desinterested cooperation, sometimes heroic, in periods of emergency and catastrophy. |
The true story of the radio in Portugal, begins around 1921 when Abílio Nunes dos Santos Júnior builts the first radio station with CS2WA as indicative. The first radio portuguese radioamateur appears in April of 1927, Abílio Santos Nunes with EP1AA as indicative. He built his radio equipment and oppened the broadcasting station "Rádio Colonial" with CS22A as indicative. With the stations shut up in 1928, he began operating in short waves with CT1AA as indicative. In 1930 appeared the first radioamateur in the island of Madeira, José da Silva with CT3AB as indicative. During this year some experiences envolving images reception sent from England, were made there. Marconi was several times in the island of Madeira exchanging information of those experiences with local radioamateurs. |

The first radio transmissions were made in normal modelling denominated modulation amplitude, "AM" using phonetic codes. Later on, after Morse's discovery of a codificated alphabet, it began transmitting in that code as well, it was called Morse. With the evolution of technology till nowdays, other kind of transmissions are used by radioamateurs. |
For the identification of radioamateur stations, contrys are classified in prefixes and the stations in indicatives. |
The radioamadeuristic activitie is regulated by several decrees and laws namely Law decree nº 5/95 and orders nº 322/95 and 358/95. |
If you want to begin the radioamadeuristic activitie, it's necessary for you to obtain an amateur-operator licence scattered in categories A, B and C. |
In Portugal, the island of Madeira and Azores there are nowdays about two thousand radioamateurs and in a worldwide level there
are about nine hundred thousand of wich 492.500 are North-American-U.S.A. |
The national entity concerning the regulation of disbanding of radioamateurs and the atribuition of Amateur-operator licence is the Portuguese Institute of Comunications-ICP on Av.José Malhoa, 12-1070 in Lisbon. |
The Portuguese radioamateurs are gathered in associations and in the REP-Portuguese Broadcasting Network that represents them in a worldwide level. |
Worldwide contests are made every year with the participation of thousands of radioamateurs. |
Sometimes radiocomunications may bring us, inedited contacts that remain in history. |
