I am currently a sub with dishnet through sbc so I do not own my recievers.I have a 811 and a 522.The other day I just started getting static on my 2nd tuner on the 522.I tried everything.Changing cables,changing the channel.Everything possible.When I go to single mode I can swap and see #2.So it has to be on the output side of the receiver on #2.Well since I am with SBC will I have to pay for them to replace this receiver?Any ideas about what could be the problem?Thanks guys!!!
