[TowerTalk] Ham IV problem

[George (K8GG) & Marijke Guerin]

Paul:

I would get out binoculars and look at the cables, etc on the tower.  The 
problem may not be with the rotator, but with a cable that has been whipped 
by the wind and may be tangles, preventing rotation further than 75 degrees.

Climbing up and having a look while someone else operates the rotator may be 
the better way to diagnose the problem.
