Radio Communication over a distance of at least 2 Light Seconds using the Moon as reflector.
(If you are trying to find us just look out for the big 2 stacked antennas, they can't be overlooked)
About (What the Hack?)
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.
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.

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.
