A favorite feed of mine just recently moved from 83W to 103W. I found out about the move only minutes before I was to start recording. Needless to say, I scurried up the ladder and made the "ghetto" skew correction quickly.
I wondered the same thing, why they'd move the feed from 83W to 103W. Best reason I can think of is that, perhaps, TP space is considerably cheaper. I wonder if its cheap enough to offset the cost of re-aiming and re-skewing every dish mounted on cinema roofs nationwide?

I doubt these are very large dishes, but maybe at 1.2 meters, it doesn't matter much. They still had to re-aim, though, unless they're using some sort of motorized setup. I've heard they're using Hughes equipment.
