OR4TN is ON5TN’s call sign from the Belgian Princess Elisabeth Station on Antarctica. Karel is a member of the team who is there on a mission to make the new base operational. That means he is there to work... If work permits, he will try to be active but it is NOT a priority. The good news (well, for us anyway) is Karel's stay has been extended until February 25. At that date the entire team will leave Antarctica. More details here.
