Just got an 811 (not sure why since they're going to be done soon but...) I have 301 receiver as well. When I hook up the 301 I get 119 and 110 with great signal strength. When I hook up the 811 I get nothing. I have single dish with two LNBs side by side (not attached to each other). I have them going into an SW21 switch. When I do the switch check on the 811 I get nothing. Unknown Switch. Even when I go to my signal meter and bypass the sw21 and put 119 directly into my 811 I get nothing. Anybody have any ideas?
