It is with deep regret and profound sadness that I inform you of the passing of Andreas HB9DGX on the night between 15th and 16th June 2007 at Lugano’s Hospital. Andreas never recovered fully from a serious motorbike accident occurred last March 4th. I have lost a loyal and true friend. Andreas, I will always remember you and will never forget the multitude of project we shared and the fantastic adventures had as amateur radio on top of mountains. 73 de Andrea, HB9DUR
