On May 21, 2023, members of the Azerbaijan radio amateur society and radio amateur club “4K4AZE” organized an expedition dedicated to the 100th anniversary of the great leader Heydar Aliyev in the Khyzin district. On the occasion of the “Year of Heydar Aliyev”, our radio amateurs used the special callsigns “4J100HA” and “4K100HA” on the air, allocated by the State Administration of Radio Frequency. Messages about the event were sent to all countries of the world by short waves.
