EME – What’s that?

The technical and operating challenge!


Earth-Moon-Earth communication, also known as “moonbounce” is (was?) one of the most fascinatig parts of our hobby. The concept is simple: the moon is used as a passive reflector for VHF, UHF and SHF signals. With a total path length of about 800.000 km EME is the ultimate DX.

Nowadays, with digital modes like JT65 or Q65, mostly everyone with a 100 W station and a single yagi antenna are able to complete successful EME contacts on 2m, 70cm or even 23cm with one of the “big guns”.
