My 2 R15 are not receiving our local channels and the even transpoders are missing on 1 receiver but low on the other for 101w. Not receiving anything on 110w and 119w is in and out so I'm leaning towards the multiswitch or the LNB. *edit* Called Directv again for a 771 and whatever signal she sent, made everything work... But then, its gone again... I'm wondering, if its the heat here affecting the LNB??? Its almost 100f today Any ideas?
