Project Moonbounce soll den Besuchern des [http://events.ccc.de/camp/2011/wiki/index.php/Main_Page 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 [[user:AndiS|OE4DNS]] anklopfen!

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.

About Project Moonbounce

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 (≈144MHz) 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.

-> see ORGA Leiwandville 3.0

Working the Moon

Call sign

There will be a special event callsign for the camp that we can use. An alternative would be using home-call signs with DL prefix.

Software/Setup

WSJT v7 using JT65B

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...


How it worked

We were very successful in producing a readeable signal that was heard from many stations on the northern hemisphere. Unfortunately and most likely due to heavy QRM at the campsite we were not able to complete a full two-way QSO. We did hear and decode some signals tough.

There is a chat-log from the chris.org JT65 EME chat. Here is a Copy to read.
