I have a pansat 2800a, and i have 3 dishes hooked up to it. One pointed at 95w, 97w, and 123w. When ever I move channels around, and mix up the channels, after a few minutes, when i tune into those channels, it says I have no signal. If I keep the channels the way they are, I dont lose signal. Is there any reason for this? Its really making me upset, because I have like 300 channels, and I want to put the channels I most watch together. How do I do this. THANK YOU!
