Is it possible to damage your recievers ability to use a switch? I am new and just starting FTA. Love it. Right now I can pick up 89w and 123W using two separate Superdishes with the Linear bandstacked lnbf's that were used for 105W by dishnetwork. My reciever is a coolsat 5000. When I attach a legacy dishnetwork 21 switch so that I can have both satellites only the satellite that I connect first will work on the coolsat. I have tried 11 different 21 switches and 2 different 34 switches. When it comes to the coolsat when I tried the 21 switches I set 89 to the legacy21 sat one port and the 123 to the legacy 21 sat two port. When messing with the 34 I really didnt know what i was doing with the committed and uncommited thing in relation the the disc switch settings. Some help there might resolve the issue.
