To celebrate the launch of our second CubeSat, [email protected], we invite the amateur radio community in a contest to listen out for our satellite.

The launch is scheduled on 22nd April 2016, from Centre Spatial Guyanais spaceport in Kourou on-board Soyuz ST-A VS14. The deployment of the satellite will be completed almost 10100 seconds after lift-off!

The competition is divided into two parts, independent of each other:

  • Be the first to send in your recorded signal and TLM packet from [email protected]
  • Be the one to provide us the major number of recorded signals and TLM packets in the first month from deployment of [email protected] in space

Prizes are:

  • [email protected] poster with signatures of the team members
  • certificate to attest your achievement
  • celebration T-shirt

Once deployed into orbit, [email protected] will begin transmitting signals to Earth approximately 30 minutes after activation. Signals can be picked up by anyone with common amateur radio equipment. You can send the recorded signals (audio and/or waterfall) and TLM packets via email ([email protected]) or upload it using the service DropItToMe (the password is radioham).
