I have DTV36EDS directv 36" international satellite dish with 95W linear LNB. My receiver is Evolution FTA. I can get about %60 quality and I can pick up signals from galaxy25 in both horizontal and vertical frequencies. I can get very clear channels from a horizontal frequency, but when I get to vertical frequencies I can't get any, even though signal quality is very similar(about %60). Is this normal? Any solutions? Also I need to slightly adjust my dish everytime when I change frequencies in the same satellite. Is this also normal?
