The Bulgarian Antarctic base "St. Kliment Ohridski" established radio contacts with amateur radio operators from all over the world using the call sign LZ0A, which returned to the air after a 19-year absence through a project implemented by Senior Assistant Ivailo Nachev from the Technical University - Sofia (TU-Sofia), the Bulgarian Antarctic Institute (BAI) announced.
For the second consecutive year, Nachev participated in the Bulgarian Antarctic expedition with his scientific project "Impact of solar activity on ionospheric dynamics and high-energy particle flows over Antarctica". It is implemented jointly by the Technical University – Sofia, the Institute of Astronomy with the National Astronomical Observatory of the Bulgarian Academy of Sciences (IA with NAO - BAS) and the "N. Y. Vaptsarov" Naval Higher School. It is aimed at studying processes in solar-terrestrial physics within the current 11-year solar cycle.
During the expedition, Sr. Asst. Ivailo Nachev also established radio contacts with amateur radio operators from all over the world, using the reissued for the period of the expedition call sign LZ0A - the amateur radio call sign of the Bulgarian Antarctic base "St. Kliment Ohridski", BAI said.
Livingston Island, part of the South Shetland Islands, is among the rarest and most sought-after locations for radio contact collectors. The use of the call sign LZ0A began as early as 1993 during the third Bulgarian Antarctic expedition by Eng. Miko Mikov. In the following years, the base's radio operator Eng. Yordan Yankov established vital communication with the world, received weather forecasts, connections with other bases and ships, as well as contact between polar explorers and their relatives in Bulgaria, BAI says.
After nearly 19 years of radio silence, LZ0A has returned to the air, generating significant interest among amateur radio operators worldwide. Contacts are established in both voice and digital modes, which have proven reliable for long-distance low-power communications. After completing the main work on the scientific project, nearly 2500 radio contacts were established with correspondents from various parts of the world, including Alaska, Japan, Europe, and, under suitable conditions, with Bulgaria.
Thus, scientific work at the southernmost latitudes intertwines with active communication with the world, turning Livingston Island into not only a research but also a globally significant communication point. The return of the call sign LZ0A to the air is yet another proof of the active and recognizable Bulgarian presence in Antarctica, the Bulgarian Antarctic Institute noted.
BTA recalls that the first group of the 34th Bulgarian Antarctic expedition departed for the Frozen Continent on November 6 with a flight from Sofia. The second group left Sofia Airport on December 16.
