First logged two-way contact bouncing off the Moon

On July 17, 1960, the first logged two-way contact via the moon, known as Earth-Moon-Earth (EME) or moonbounce communication, was achieved on the 1296 MHz frequency. This historic event involved the successful exchange of signals between American radio amateurs William L. Stearns (K6DUE) and Raymond Heald (W5LUA). Utilizing the moon as a natural satellite reflector, their pioneering efforts demonstrated the feasibility of long-distance radio communication by bouncing signals off the lunar surface. This milestone in amateur radio showcased the potential for EME communication, inspiring further experimentation and technological advancements in VHF and UHF bands, and expanding the horizons of amateur radio operators worldwide.
