One of the best Ham-Radio operators died. Its so sad, thousands OMs will miss him a lot. He was really top. A real disaster.
I remember Harro from the 1970s when he was still active as DJ6RB. He was a ophthalmologist in Erlangen where I was a student at the time.
Ham radio was a great way to keep in touch for him. Last Friday at our local bulletin on DF0ANN his death was mentioned and quite some OMs still remembered him.
