[QUOTE="Robbo, post: 426979, member: 256551"] If after you've done what Yorks has said and you're still not getting it, there is a method to check what your arc's doing. I can't remember where I saw it now though. But basically using graph paper (or spreadsheet graph) you plot what your arc should look like ( elevation on vertical axis, azimuth on horizontal). Then you move the motor around the arc and measure how far off your elevation is. This will enable you to plot your arc. How the arcs compare will tell you whats wrong:- one arc above/below the other -- elevation wrong One arc steeper than the other -- motor latitude/elevation wrong One arc offset horizontally from the other -- motor azimuth wrong. One arc skewiff with the other -- pole not vertical. A comination of all four --- you've really bu99ered it up. Never had to do this myself, as fortunately my house faces perfectly south, and worked fine when I first put it up with the motor bolted directly to the wall ( lack of time). [/QUOTE]
