Ok I would start by saying sounds like a standard linear lnb. Setting would be 10750. Next got for 11800 on G10R. May not have the channels you are looking for but a decently enough solid signal. You can check
www.lyngsat.com for the total transponder info. You are attacking the problem decently but you need to skew your lnb for the particular sat you are trying to receive providing you are a fixed dish.
If you are a motorized system all bets are off. Everything is handled differently. Motorized?
