Earth-Moon-Earth (EME) Moonbounce for Ham Radio
Find resources and guides for EME moonbounce operations, including station setup, software, and operating procedures for amateur radio.
Earth-Moon-Earth (EME), often called Moonbounce, is a challenging amateur radio activity where operators bounce radio signals off the Moon to communicate with other stations on Earth. This mode requires high power, sensitive receivers, and large antenna arrays to overcome path losses, making it a true test of a station's capabilities and an operator's skill in weak signal work. EME activity spans VHF, UHF, and microwave bands, with many hams building specialized equipment for these demanding QSOs.
Hams interested in EME can find resources covering everything from beginner guides for small stations to advanced operational procedures for digital EME. Many operators share their experiences, station setups, and audio recordings of Moonbounce signals. Tools like EMECalc help predict signal levels and optimize station performance. The WSJT software suite, including protocols like JT65, is widely used for its ability to decode extremely weak signals, making EME contacts more accessible.
