First Earth-Moon-Earth-Radiostation (moonbounce)
on 70cm/23cm/13cm-Band  from EA6.

Earth–Moon–Earth communication (EME), also known as Moon bounce, is a radio communications technique that relies on the propagation of radio waves from an Earth-based transmitter directed via reflection from the surface of the Moon back to an Earth-based receiver.
