I am installing a 1000.4 dish with a 722 receiver. I am looking for eastern band sats 61.5, 72.5, and 77. When I run a check switch I get a 1 0f 12 and I cannot get the correct sats . I am connected to the second port (72.5) on the LNB and getting a great signal strength on my meter. Does anyone know what is causing the failure to get the sats online ?
