Hi, My friend have two pansat 2700a want to have it hook up both receivers to two single LNB on sat 91 and 82. I read that if you hook up the first receiver to (if output) and hook the other with the (if input) then I should have all the chanels. My question is I only have a few (about 30)chanels on the other receiver. Do you know what do I have to do to get all the chanels on the other recevier? thanks
