If 129 and 110 are good but not 119 you may have something blocking the view. What does transponder 21 on 119 show? It should be above 60 might even be able to get 70.OK guys we are getting closer! signal on 129 trans 23 and 29 is 50. 119 trans 16 and 18 is about 35. 110 spotbeam 11 is 80, 9 is 80, 10 is 50 and 8 is 0. Does this mean anything because I'm missing several channels.
What you can do is set it to 119 transponder 14 (I actually like this one for pointing), then go gently with only one finger pull up down left right and see if it goes up. We are aiming for atleast 58 on transponder 14 but hopefully 65+. If you get good signal there the rest of the satellites will also be good assuming your scew is set correctly.
