Every year the UAFS Amateur Radio community launches a new Ballon mission.
This year it was on the 10.05.2003. It was the first time I could not only listen to the ballon
but also was allowed to work it. On 9.22 UTC I was able to get through the enormous pile up.
The Callsign of the Ballon was OE2XYL.
You can find further details about the Mission on the SARTOB 8 homepage


Finally some pictures of the event:
