I've tuned in my satellite on channel 085 and have 98 signal....however when i tune into TSN channel 099, or CBC channel 033 i have 0 signal. I've tried adjusting the skew and elevation and rotation but every time i do that it seems to lessen the signal on the existing channels without increasing the signal on the ones i can't get.....I'm getting frustrated....Please help!!!

Thanks

Cory
