13 meter mast climbing by mast ladder on my own - repairing wind mast unit

Using my mast ladder to climb the mast on my own (single handed). I removerd the NASA CLIPPER WIND mast unit because the wind speed was not reported correctly. It turned out that the HALL element was drawn in water and one PIN vanished by corrosion. After replacing the HALL element fromn an old unit the mast unit was mounted again. This is a small vieo made by an action cam mounted on my head. Still a boring nine minute video, so need to look every minute, maybe just the mast ladder is of interest...
