May also improve if the offset LNBF were aimed closer to the center of the dish. (Spacer at rear of LNBF?)
That's what I was trying to say, it needs to be straightened out somehow.
Also, the calculator at thelist.satelliteguys.us outputs the correct skew for 103W Ku, or at least it did the last time I checked.
Finally, SES was supposed to replace that satellite sometime this summer, but I haven't seen anybody say that the new satellite has started to move yet, so I don't know what's going on.
