I read your last post and went to see what I could get on those two sats.
I was able to get "PA Cable Network" and "Once TvMexico" (both at 66% Q)
on 83W C-band. Nothing at all on 72W C-band.
I am still able to get Ku-band channels on either sat, RTV, TuffTV on 83W, and
the NBC mux on 72W (AMC-6).
I see you're in Georgia, and getting the western sats quite well, but not the eastern ones.
This makes me think that your polar alignment might be off a bit, or your pole may have
come away from plumb with the weight of the dish on it?
Have you tried for anything further east yet? Intelsat-9 at 58 West has good signals
to try for. "NHK Japan" comes in nicely here.
I think you might have a bit of tweaking to do.
