OK, to properly align a dual LNB (or more) dish, you set the dish to look in-between the two satellites, for 97W and 101W you take and deduct 97 from 101 and divide by 2, this gives you an offset of 2 degrees, you then set the dish to 99 degrees.

As to what satellite to tune up on, look at the programmed switch settings you have for the #1 Diseqc switch for the first LNB for what ever satellite. (Diseqc port #1= 97W?? or Diseqc port #1= 101W??) Then pick a transponder on that satellite that is in the open.

And if you need to adjust one or the other LNB for a satellite, remember that the signals are criss-crossing each each other, the LNB for 97 would be on the right hand side of the LNB mount, and the LNB for 101 would be on the left. (looking from behind the dish)
