    i just rewired my house. I am now getting intermittent pixilation and 771 on some HD channels. Bravo , east coast max , syfy. It is fine now which makes me believe it is a D problem or sunspots. Anyone having similar problems? Before i call my installers back i would like to find out. since the walls we open, i wired with 2 cables + cat 6. I have 2 hr 20-700 and 1 hr 21-700 all stacked. all with the same problems.

    Also, can anyone tell me wher i can find out what my signal strenths should be?
    I am in LA CA.

    Thanks for your help

    You could either go after "the channels", or simply get an overview of the levels off the 99c & 103c SATs, which really would be more informative.

    Where can i get an overview? I am looking to compare my signal to some standard.

    Pull up the SAT signal level screens and see what the 99c & 103c shows.
    If your levels are 70+, you're meeting the minimum. If they're below this, you'll have problems and maybe need the dish aligned.
    80-90+ is good.
    This is as close to "a standard" as you'll find.

    my signal strength is fine. what i am trying to for is a general grid list so i can tell if where i have 0s i should or not. in other words, i am looking for a list of active and inactive transponders

    Thanks, i have seen that. What i am looking for is a list in the same form as we see when we do a strength test. something showing even minimum coverage would be helpful.

    :confused: I really don't know what you're looking for.
    There are beam coverage maps, but not by channel or TP.
    Your title seems a bit misleading since this isn't a pixelation or 771 error problem it seems.
    Are you having problems with some channels?
    If so, how could your "signal strength is fine"? :confused:

    Sunspots can indeed interfere with EM signals, but They are only really an issue for communication sats when sun flares are strong enough to burn out sats in their path, which would be a problem for everyone and would mean that DTV would be scrambling to move new sats into place to replace them. We're talking rare front-page news. You won't see occasional reception problems caused by sunspots.

    Maybe you are thinking of sun fade, when the sun lines up behind a sat and overpowers the LNB with direct RF, but that only happens for 10 days in early March and October, and only for 20 minutes a day at a time (20 minutes on the 3rd or 4th, less on days earlier or later than that).

    If you do not have at least a 96 on at least two transponders on either 103 or 99, you need a realignment (ignore the lower numbers).

    Thanks, My problem seems to be gone. I think it had to do with D and not me. I was just concerned because as i said, i just rewired my house and did not know if the problem was coming from that or something else. If it was the wiring i would have the installers fix it. if it was the dish, i would call D (protection plan). I am surprised that no one else had a problem, but perhaps they were not concerned because of no other issues.
