Kantuta Expeditions on the balsa raft from Peru to Polynesia. Kantuta Expeditions The Kantuta Expeditions were two separate expeditions on balsa rafts led by the Czech explorer and adventurer Eduard Ingris. The voyages were inspired by the Thor Heyerdahl's Kon-Tiki expeditions. The goal of the expeditions was to repeat the success of the Kon-Tiki and confirm Heyerdahl's thoughts about the migration of Peruvian people to Polynesia. The first expedition, Kantuta I, took place in 1955/1956 and led to failure. In 1959 Ingris built a new balsa raft Kantuta II and tried to repeat the previous expedition. The second expedition was a success.
DX-pedition reliance on amateur radio for communications was that of Kon-Tiki organized by Thor Heyerdahl in 1947 and using call sign LI2B. The activity of dedicated DX-peditions was pioneered by one-time ARRL president Robert W. Denniston, W0DX. Mr. Denniston's 1948 DX-pedition, using call sign VP7NG, was to the Bahamas and was called "Gon-Waki" ala Thor Heyerdahl's "Kon-Tiki" expedition the previous year. DX-peditions are planned and organized to help operators who need to contact that area to obtain an amateur radio award. There are several awards sponsored by various organizations based on contacting many different countries. Perhaps the most famous of these
