Tony,
That was my problem over the summer, get one in, lose one. I just checked the signal strenght, haven't done it in a while and I can't
believe what I seen, get this, THIS TV 99 to 100%, ME TV 98%, RTV 3800 89% and RTV 4080 74%. That on an 8ft solid with cloudy skies and rain. When I was adjusting in June and July I was struggling to get 3800 at 64%. I needed that much for stable video, 4080 was out of the question. It might be coindence, but after I zeroed in on AMC6 and got the high signal there the rest of them fell into place. As I told you before, now my only problem is the weak ESPN S2.
