'It's good news for all ham radio interested in polar contacts. Oleg made a very good job last season with callsigns RD1A/MM, RI41POL and RI0POL making more than 205,000 contacts. The vessel departed Murmansk on September 15 with a team of scientists aboard, and is heading towards the Novosibirsk islands. This is where the drifting polar station will begin its work as part of the "North Pole-42" expedition. For many months, polar explorers will conduct research in the high latitudes of the Arctic Ocean, encompassing over fifty scientific programs.'
