Today, 18 April 2022, is World Amateur Radio Day https://www.iaru.org/on-the-air/world-amateur-radio-day/, which celebrates the establishment in 1925 of the International Amateur Radio Union (IARU), in Paris, France.
In Portugal, ANACOM is the body in charge of managing the radio communications spectrum and services, which includes amateur and amateur satellite serviceshttps://www.anacom.pt/render.jsp?categoryId=331644.
The amateur service is a radiocommunications service that aims for the personal training, intercommunication and technical studies of amateurs, that is, duly authorized persons interested in radioelectric technology on a purely personal basis and without any financial interest. The amateur satellite service is a radio communications service with the same purpose as the amateur service, but with the specificity of using space stations on Earth satellites.
To be a radio amateur in Portugal, you need to hold a National Amateur Certificate (NAC), issued by ANACOM, which can be obtained by concluding an amateur aptitude test or by holding an international certificate recognised for this purpose.
There are currently around 5300 NAC holders in Mainland Portugal and in the Autonomous Regions of Madeira and Azores.
