Hi all. I have a ham IV turning a TH-11DX which has been working fine for
over a year. Prior to that, it turned a KT-34A for about 10 years. When I
put up the TH-11DX last year, I performed normal maintenance on the tower
including greasing the thrust bearing. Everything seemed to be aligned OK.
I haven't used the antenna for a few months.
Today, I went to turn the antenna and noted that it works from about NW to
East but that it binds up beyond these directions and stops turning. I've
checked the rotator bolts and they are tight. The rotator makes all the
normal sounds in the sectors in which it rotates.
Any thoughts would be appreciated.
