I have a Dish 500 dish and a 522 receiver. The LNB is the DishPro Plus with three coax connections (1, 2, LNB IN). I have the Separator for the 522 receiver that takes the single line from the LNB and splits it into the Sat 1 and 2 inputs on the back of the receiver. According to info I found elsewhere, it says to run the single RG6 coax from port 1 on the LNB to the separator. So I've done this. When I run Check Switch, it comes up saying there's a problem "that may adversely affect operation." When the results screen comes up, it's saying RECEPTION ERROR in red next to Status. I see "Conn" under ports 1 and 2 of both satellite inputs, and X's next to Trans. The switch shows up as a DPP Twin. On the Details screen, it says LNB status is Direct connect to DPP-Twin. Ports 1 and two it says Good Connection, No Signal. The dish is aimed as well as I can get it using one of those little accessory satellite aiming boxes. But I still show no signal coming into the receiver. Any ideas what's wrong? Thanks! Rob
