The challenge was set to decode a message from FunCube1 satellite and then answer a set of questions to get the settings for the enigma decoding engine.

We had some great fun setting this up and getting the full message eventually.
Thanks to all who helped set this up.
Here is our video of the fully decoded message
"DEAR SCOUTS SPACE TRAVEL IS THE FUTURE GO ON A JOURNEY IN SPACE NOT ONLY DURING THE JOTA JOTI BUT THROUGHOUT THE YEAR RADIO AMATEURS CAN SUPPORT YOU HOPE TO MEET YOU IN THE FUTURE"
We got a couple of mentions on Amsat-UK web pages:
