Done and done and done! I ended up doing a bit more iteration (back and forth between the left-right and up-down adjustments) but I've now got it landing on G19 at its
default position for 97W.
Yep, ended up with a page or two full on my receiver's search. Didn't double-check that my receiver has all six of the right transponders but I can mess with that later if it turns out I'm missing something interesting but still DVB-S / MPEG-2 compatible.
Yep, can see definite signal degradation as soon as I skew the LNB either way from "straight" (seam on the LNB lined up with the clamps on the mounting bracket). Will make setup easier if I want to try swapping anything else in!
I don't know if there's any good (unencrypted, DVB-S) satellite farther away to really check the sweep against, but I was at least able to program in my original find at 101.0 W back in (now at the correct "12000 V 20000" setting) and can get both birds automatically.
Shouldn't be *that* exciting since it's just an ad, but still really fun to choose channels on the other one and have it jog over and lock on
