I recently purchased a 942 and it isn't working so well. The current set up is a Dish 500 with the dual LNBs...it was installed at the house when I moved in. It has a Dish SW-21 switch so it has the two cables off the LNBs leading to the switch then one cable coming into the house. I understand that the 942 needs two inputs to work properly, so I purchased a Dish separator and plugged the two outs into the 942. The 942 is still acting like I have a switch problem. I was looking through the archives and if I'm interpreting them right I have three options...running two sets of coax (which I don't particularly want to do), purchasing a DP44, or running one line off my LNBs to a separator (which I thought I just did). Is it the SW21 switch causing a problem? What would happen if I just disconnected the 2nd LNB from the switch...could it be that easy? Any help/recommendations are appreciated!
