[TowerTalk] Yaesu G2800 SDX limited rotation

[Grant Saviers]

My G2800 SDX rotator only rotates 350 degrees, the manual says 450 with 
the overlap feature.

When the overlap light comes on the mast rotates another 90 degrees CW 
(right), so that seems about right.  In the other direction (CCW, left) 
it stops short for 350 deg total rotation.

I've been to the tower top, loosened the mast and it is free to rotate 
and the coax isn't the problem.

Any thoughts as to what else I should check or look for if I remove it?  
Could it be a controller problem?
