EME (Earth-Moon-Earth) com­mu­ni­ca­tion, also known as “moon­bounce,” fas­ci­nates many ama­teurs. The con­cept is sim­ple: use the moon as a pas­sive reflec­tor of VHF and UHF sig­nals. Con­sid­er­ing the total path of some 500,000 miles, EME is the ulti­mate DX — at least to date. The first two-way ama­teur EME con­tacts took place in 1960.

Tra­di­tion­al­ly EME was a CW mode activ­i­ty requir­ing large anten­nas and high pow­er. Advances in tech­nol­o­gy, such as low noise receivers and dig­i­tal sig­nal pro­cess­ing (DSP) tools, are mak­ing EME con­tacts pos­si­ble for more and more ama­teurs with mod­est sta­tions
