#Ehf echolink stations license

Amateur operators must hold an amateur radio license which is obtained by passing a government test demonstrating adequate technical radio knowledge and legal knowledge of the host government's radio regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station licenses with a unique identifying call sign, which must be used in all transmissions. The amateur radio service ( amateur service and amateur-satellite service) is established by the International Telecommunication Union (ITU) through the Radio Regulations. The term 'amateur' is used to specify 'a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest ' (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.). Amateur radio, also known as ham radio, is the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications.
