Moon bounce, also known as EME (Earth-Moon-Earth), is a communication technique that allows two earth-based radio stations to communicate directly by using the moon as passive reflector.
 
 
 
Project Moonbounce is a Project done by the members of MetaFunk, the Amateur-radio group of the Vienna-based hackerspace Metalab, in cooperation with Chaoswelle. It is a part of [[Leiwandville]].
 
 
 
 
 
= Setup =
 
 
 
Most EME communications are on the 2 meter (144-146MHz ITU region 1) amateur radio band.
 
 
 
We will be using two horizontal stacked 5m long yagi antennas on an about 6m high antenna mast.
 
We are using a 2m high-power linear power amplifier for transmitting and a low noise amplifier (LNA) to amplify the received signals.

= History =
 
 
 
First developments in using the moon as passive repeater have been made in the early 1950s by the United States Navy. It was ment to be a reliable communication method for two radio stations which were unable to communicate by shortwave radio because of bad propagation.
 
 
 
It's military use became obsolete with the deployment of artificial satellites.
