Repair of the rotor for the 10 meter Yagi antenna
The rotor at the base of the Yagi antenna for the 10-meter band no longer worked reliably, the control unit could no longer detect the current direction of the antenna. Therefore the rotor, a Daiwa MR-750, was dismantled and disassembled together on May 1, 2022. It quickly became clear that a connecting cable on the potentiometer for direction detection had come loose. Inside the rotor had also accumulated a lot of white powder. Presumably, this was aluminum oxide, which had formed in recent years due to corrosion.
In the morning of Mai 8, 2022, those present removed the white powder with compressed air. On subsequent Sundays, the rotor will be lubricated, assembled and reattached to the mast.
