Jamboree on the air challenge *servicekring* Enigma Funcube decoding

Received a very nice letter today from Wouter PA3WEG and Jeroen PE1RGE, thanking us for participation in JOTA / JOTI Scout enigma challenge on the funcube 1 satellite.

They sent this letter and some very fancy badges for the Scouts to sew on their uniform


Great big thank you and looking forward to this years challenge!



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:

Bias Tee virtual buildathon #vbuild is back

Chertsey Radio club 

In association with 

GazLab's 

£12 Including postage


email jamesm0jfp@virginmedia.com

We will be running an evening session in the next few weeks and building the Bias-tee kit.
This simple kit helps supply 12 or 18 volts to the satellite dishes LNB, this in turn powers either the horizontal or vertical antenna amplifiers. The Narrow band (voice, CW, data) is Vertical, whilst the TV band is Horizontal. The kit contains 10 components (full size, no SMD!) and its estimated between 15 and 45 minutes to build and test the board.
We will be running the sessions using ZOOM platform and will share video and audio with the group. All videos of the build will be shared after the event on this site. You will need basic soldering kit, snips and at least a multimeter to run the electrical tests. To receive Es'hailsat 2 (QO-100) you will also need an old satellite dish and a reasonable LNB, available on ebay for about  £12 including postage. The last thing you will need is a cheap SDR dongle, these can be easily purchased for about £15.

Setting up and pointing the dish, is a combination of fun and stress, but once you pick up the signal the satisfaction will overwhelm you.

To Register for your place please email jamesm0jfp@virginmedia.com
