My HDR-300 Rotor is hesitating or stopping while turning the array. The
rotor is about 30 years old. It's turning a 2 ele 40 and a TH6DXX. As well
as a couple 2 meter long yagi's. I don't believe there is a mast bearing
problem.
I have a few questions:
The motor start/run capacitor measures about 100 uF on my cheap handheld
meter. I have other DC capacitors that measure in their correct range, but
they are DC and not AC caps. Does it make a difference?
The other possible issue is the motor seems to be somewhat noisy when
turning, which makes me wonder if the bearings in the motor are going out.
Is this normally a quiet motor?
