I am a complete satellite novice. I have a KVH Trac Vision R4 Dish on my RV. I have no problem getting Sat 119, but can not get 110 to come in. The cables seem to be properly attached and nothing is loose. Any ideas from the experts on what to do? I have run check switch tests and only the 119 shows. The Sat. 2 is x'ed out. Any help will be appreciated
