Look, I'm not here to debate anything.
Bottom line, this guy has a crap install, two dishes, half his transponders on a receiver.
I wouldn't be surprised to find out anything with this system. How his lines are ran, how it ain't grounded, switches, blocks, splitters, rg-59, barrels, etc.
So, telling me that an installer left a splitter in his system is believable , but that he doesn't have a switch isn't? Ok, fine, you win that one.
All, I'm saying is this system is needing some repair and when I diagnose things I tend to think "out of the box". Especially on a install like this one. You don't need two dishes so who knows what the other dish is? did he say? does he really know? Not enough info.
so Stop assuming you know more then me, when you don't.
Because an 18" and kaku on the roof doesn't make any sense to me. But this isn't a normal install from the sounds of it.
He said he wanted to try and fix it himself, so I was trying to narrow things down and help him out.
More info is needed on what the OP has tried, what his setup is, and what he wants to do.
