    I am experiencing an issue with only one station, but it is on both of my HD/DVRs. The channel is my local NBC in HD ( which is coming off of the 103(s)) In comparison, both HD/DVRs are receiving the same signal strength on all sat. on both tuners. This leads me to the conclusion that the problem is not the receivers.
    I should be getting (or at least I am told by the guide) 16 out of 32 transponders on the 103(s) bird.
    Transponders read as follows:
    1-8 36 98 0 0 58 99 n/a n/a
    9-16 na na na na na na 77 100
    17-24 0 0 92 99 88 0 60 93
    25-32 all are n/a
    The 103(c) is were most of my national HD feeds are coming from and transponders from there AND the 99(c) are all above 89. I have realigned the dish although in didn't need realigning. I have also bypassed my 6x8 multi-switch and am still receiving these few low numbers on the same transponders. I even have replaced the LNB just to see if that was the root of the problem. Still no luck. So my question is why am I getting five zeros and three other random transponders at less than 80? Am I even using all of these these transponders? What do I need to do to fix the problem?
    The problem-channel is working fine 85% of the time; we are just experiencing very bad pixelization from time to time. Any input will be greatly appreciated and thanks to all who make this site what it is!:confused:

    Spotbeam transponders are aimed at particular geographic areas of the country. Most cities have locals carried on one or at most two different spots. In your case they are likely on one or two of the very high readings, while the other spots are intended for other geographic regions. Therefore, low readings and/or zeros on many 103(s) and/or 99(s) transponders is completely normal.

    As for what is causing your problem with pixelation on one particular station, that's something probably best brought up in the Programming Forum here. Note that there is a sub-forum linked at the top of that section for issues with particular cities' HD locals. Find the thread for your city and see if others are having the same problems. If so, it's likely to be an issue with that station and/or its feed to Directv, not your equipment.

    103(s) is a spotbeam satellite. You'll only see high signals for the transponders that are beamed to your location; you'll see low signals for spots that you're on the edge of, and 0's for TPs that aren't used at all in your area. That's all normal.

    The problem you're having may not have anything to do with your sat signal strength; it could be an issue with the feed from the local station to DirecTV, or a problem with the equipment on either end.

    Thanks for explaining the spotbeams to me. I was a little confused as to how they worked. Now I need to figure out what is causing my pixelization.

    I don't believe that the problem is with my equipment because both HD boxes have identical numbers on every sat transponder within to or three percent.

    how long are the cable runs from the dish to the recievers.you may have an integrity issue with the cable.total length should be less than a 100 ft .unless you have quad shield rg 6 with solid center conductor.copper clad steel css wont work well with long runs

    Where in PA are you located? If you're in Harrisburg or Phila, then your transponder is 15 with a reading of 77. I'd say you need to align your dish. I had a similar situation where some of my readings were in the mid-90's, but the transponder carrying my LiL channels was around 70. I had to realign my antenna and that solved the problem.

    If you're in State College, your transponder is 6 with a reading of 99. No problem there.

    Scranton, the txpndr is 19 with a reading of 92. No problem there.

    For some reason I couldn't find the Erie stations, and Pittsburgh looks like they're on the 99W. All of this info came from gct's post near the bottom of http://www.dbstalk.com/showthread.php?t=140519&page=3

    Antenna alignment aside, if all of your HD locals are fine except one, I agree that it's not an issue with your equipment.

    Good luck!
