→ Project Moonbounce |
Radio communication over a distance of at least 2 light-seconds using the Moon as reflector.
Anyone interested in actually talking to him/herself? We can do that - you're welcome.
- Preface in German language:
Project Moonbounce soll den Besuchern des Chaos Communication Camp 2011 den Amateurfunk allgemein und eine seiner spektakulärsten Spielarten im Besonderen nahebringen. Erde-Mond-Erde (EME, Moonbounce) Funkverkehr direkt auf dem Camp und für alle zu bestaunen. Das Camp ist, wie unsere Zielgruppe, höchst international und die Sprache größtenteils Englisch. Die Moonbounce Projektseite ist daher ebenfalls in Englisch gehalten. Sollten trotzdem oder grade deswegen Fragen auftreten, einfach bei OE4DNS anklopfen!
About
Project Moonbounce's aim is to provide the visitors of 2011's Chaos Communication Camp some interesting insights into amateur radio in general and into one of its most spectacular varieties in particular. Earth-Moon-Earth (EME, Moonbounce) radio communication directly on the campsite and for everyone's amazement. Since the camp's language is mostly English due to the very international audience, this site is as well.
Project Moonbounce is part of Metalab's Leiwandville 3.0 and provided by the people of MetaFunk in cooperation with amateur radio operators from the CCC (Chaoswelle) and from all over the world!
This site is used for organizational purposes. Pse add all infos/thoughts/help offers/donations and whatever you think might help us to reach our goal!
Facts
- We will work in the 2m Band using 2 long Yagi Antennas and a high power amplifier.
- Togehter with the Chaoswelle we will also be partaking in all other Hamradio Activities on the Camp.

Testing
After collecting all equipment a testing setup will be created to check if all components are working, if nothing is missing and if we can improve our setup.
Clemens suggests Stadtflucht4 (roughly 1 month ahead and 2 weeks after Ham Radio)
Transportation
At least one truck and one big van with trailer.

Working the Moon
Callsign
There will be a special event callsign for the Camp that we can use. An alternative would be using home-callsigns with DL prefix.
Software/Setup
Conds - Space-Weather/Moon constellation
- Moon is full which does not really matter but looks nice :-)
- Earth-Moon distance: 395000 km - could be closer but we're not going to change that.
- Path in the sky at Finowfurt...
