While on the subject of thrust bearings, has anyone had experience with the
Yaesu GS-065 seizing up due to lack of use? Due to prop pitch motor
difficulties I didn't get to do much turning for about a year and find it
now turns even slower (e.g. 1/4 rpm) whereas it used to be perhaps 3/4 rpm
and I'm wonderig if the bearing may have rusted up or ??? I have moved the
power supply from the top of the tower to the base and and run 100 feet of
12 guage down the tower. Guessing at 10 amps, I raised the voltage to about
36 VDC. Used to be about 24 VDC at the rop of the tower. Maybe I need to go
to 48 and hope it's not the brushes. How high can you run one of the small
ppm's without burning it up ?
