ABSTRACT
Amateur radio (also called ham radio) is a nonprofi t, non-commercial and private recreation of exchanging messages via voice and data communication using designated segments of the radio frequency (RF) spectrum. Amateur radio enthusiasts generally use the RF spectrum to contact people from all over the world, carrying out wireless experimentation for self-training and for some types of emergency communications (ARRL 2010). Amateur
radio operation is regulated and coordinated globally by the International Telecommunication Union (ITU), a branch of the United Nations (UN) (ITU 2008), and licensed by national governments that regulate operational and technical characteristics of radio frequency transmissions and issue individual and group (club) stations with an identifying call sign (an unique identifi er composed of letters and numbers).
