Well, it wasn't the rain messing up the dish, it was the stupid junk SG2100 motor. The day it poured the dish messed up and it's been getting worse in the last week or so to the point where nothing came in, today I got a chance to go out and check it out, it's the motor. Sometimes it moves, sometimes not, sometimes it stops a bit before it gets to where it should be. No flashing error light, which is odd, but I'm thinking that maybe water got into the motor somehow when it rained and is messing it up.
This motor has been one of the most annoying things, it'd work for quite a while, then start messing up, which is why I'd stopped using it before. I'd figured it was weak and cheap, but maybe the problem is when it rains, moisture getting into it.
I removed the motor and just set the dish up fixed on 87W, working great. I'm going to pull the motor apart and see what's going on with it. If it's not something obvious, that motor will most likely end up in the scrap pile, it's been problems right from day one when I bought it.
