Our trip is over and it was a huge success! (apart from lost luggage and so on..)
The flea market was the biggest surprise, every thing (radio related) you might want to buy for a euro coin is there!! From simple connectors to complex spectrum analyzers it’s all there.
The balloon launch had some nice features such as morse code, SSTV, voice and multiple independent payloads made by students form different European countries.
Some photos and videos:
