I found RT6T in Stavropol Russia this morning at 5,804 miles. This city is the home of Mikhail Gorbachev. A brilliant man, he led Russia into a more democratic and open society. Many of his reforms were not well liked; but he moved Russia into the modern age. He was the recipient of the Nobel Peace Prize in 1990.
I also worked E77DX in Bosnia and Herzegovia and HB9CVQ in Switzerland.
