On the Air

Ama­teur Radio is an activ­i­ty with many spe­cial inter­est areas and an activ­i­ty of con­tin­u­ous self-train­ing. Radio ama­teurs have avail­able a wide range of on-air expe­ri­ences which con­tribute to their self-train­ing and sup­port exper­i­men­ta­tion and explo­ration of radio technologies.

Activ­i­ties include:

  • Explo­ration of dig­i­tal sig­nal pro­cess­ing techniques
  • Devel­op­ment of new anten­na systems
  • Pub­lic ser­vice for emer­gency communications
  • Prop­a­ga­tion exploration
  • Low pow­er communication
  • Explo­ration of anom­alous prop­a­ga­tion modes, includ­ing tro­pos­pher­ic, ionos­pher­ic and grey-line, trans-equa­to­r­i­al, chordal hop, mete­or scat­ter and Earth-Moon-Earth
  • Wide­band and nar­row band dig­i­tal television
  • Use of ama­teur satellites
  • Using com­pet­i­tive aspects of ama­teur radio (con­tests) to improve equip­ment and anten­na performance

This sec­tion of the web­site is main­ly of inter­est to those who are already radio ama­teurs or lis­ten­ers. It describes some of the on-air activ­i­ties spon­sored by IARU or relat­ed to IARU’s work. Oth­er on-the-air activ­i­ties are spon­sored by nation­al IARU Mem­ber Soci­eties and by a wide range of spe­cial inter­est groups. Detail of these can be obtained from Mem­ber Soci­eties in the coun­try concerned.
