Just to clarify (and expose my ignorance)... skew is the rotational alignme=
nt=20
of the LNB relative to the rest of the dish, right?

Nope.

Ok.  I'm guessing my general dish alignment is good based on the signals fr=
om=20
the Sky/TV3 etc transponders:
Signal strength: 62208
SNR: 64401

So I should be able to scurry up on the roof and rotate the LNB from two=20
extremes until I lock on to 12483 then bisect the angle and tighten the=20
screws?  Then verify that I'm getting the other transponders at the same or=
=20
better signal strength.
