Thanks sunrise/sunset and tower shadow trick. I had not heard that one. I
am putting up a tilt over tower, so I want to know the azimuth in the
direction that it is tilted. The beams will be installed with the booms
vertical. The whole idea is to preset the rotator so then erected the
rotator control will be correct, not necessary true north. Who ever made
the comment about it being a neat site it right. You can find lat/lon for a
particular zip code if that was something you needed.
