I have a pansat 3500sd. I pick up 110 & 119 fine they are run to switch 2 & 3.I am receiving them on two seperate old DTV dishes. The third dish which is different shapped than the others more horizonal a disnet dish , I have been trying to get 61.5 or 129 and cannot get nothing. The signals will not even change on the installation screen. Could it be something wrong with the switch , or the receiver. I set the sat. at Echostar 3 and the dish is pointed correctly. I have moved it everywhere , even tried to pick up the 110 or 119 on Echostar and get no signal variation. No quality ever shows up. Should I have thesame type of dish as the old direct TV. I have gotten 61.5 before , but on a different size dish. Can anyone help me
