In Earth->Moon->Earth (EME) communication the signal echoed back are so weak that only very efficient and simple modulation techniques can be used. The traditional and classical system used by radio amateurs is telegraphy (CW) where the basic information encoding allows detecting and decoding very weak echoes.

With the use of computers a new digital system where all the encoding and decoding of information is done by software has recently became popular in the EME community.

Phone transmissions are also used but they requires higher signal levels and therefore are only possible between well equipped stations.
