I was trying again today, and the gutters and downspout are awfully close to the proximity of the dish path, too close for comfort. I got very close to what i needed, but  the receiver never moved off of yellow.  I read your post Catamount, and I'm not sure which is the skew adjustment, except there was a adjustment for a twisting of the arm holding the LNB, so I would assume that is it.  I  did try turnthat in both directions for the strongest signal.   I feel that i might have to put a pole in concrete and move the dish away from the house a bit. The path is in the clear, so I have to think that the gutter down spout is messing with me. I can only verify this if there is another strong satellite I can get from here, that will have me swing the dish so far south.
