Moonbounce at LeiwandVille

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. It is the longest communications path two stations on Earth can use to communicate directly with each other.

EME Setup

EME Shack

We are not the first people doing EME, so we're fairly sure we won't blow up the moon (we're not using any really strong lasers).

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 Village:LeiwandVille.


Most EME communications are on the 2 meter (144-146MHz ITU region 1) amateur radio band.

We will be using two horizontally stacked 5m long yagi antennas on an about 8m 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.
