    Forget 99b -- that's someone else's locals. Yours are on 103a 2, 4 & 6. Your 103b signals are fairly typical for the west coast, and the rest seem within reason. 101 is SD, 110 & 119 are HD Mpeg2, largely.

    You are getting pixelation on what? new HD? old HD? SD?

    There are just WAY too many people who have this problem, and it is spread out all over the country. I'm in S/E Wisconsin, and the highest signal I've seen on 103b is 80, but average 74.

    How can all these people all of a sudden need an alignment?

    I can see some issues in a particular area or 2, but this just seems ridiculous.

    All my other signals are between 89-100 on all other sats except the 103's.

    Now if the 103's are in position, they would be between 101 & 119, so why can I get high signals on those but no ones in between? These numbers all represent the position in degrees

    It just does not make sense unless the Sat itself is not completely in it's final position. If that's the case, then making an adjustment right now seems like a bad idea, cuz if there are position changes later, wouldn't I see problems?

    I've got the AT-9 (sidecar), but unknown about the specific LNBs.

    All OK here this morning. As I recall yesterday in the afternoon it was overcast with rain earlier. I will have a look tomorrow, more rain is predicted.

    I'm having the issues on all 3; new HD, old HD and SD. Virtually all of this started when D* began "testing" the new HD channels and has worsened with the subsequent release/rollout of the new HD channels.

    I posted in another thread about the horrible audio/video issues with Desperate Housewives (ABC) this past Sunday. I am glad that HD is finally coming to fruition. That said, overall, the audio/video issues are now much more pronounced and frequent.

    The 101, 110, 119 SATs are Ku which had a wider beam [due to frequency] and the Ka is only about half as wide a beam so many dishes have only been aligned to the Ku and since Ka is now active nationally may need to be fine tuned better now.

    I am right there with you strength wise, near the Sac/Placer county line.

    82 91 80 85 80 89 79 85
    80 86 80 85 83 88 NA NA
    83 NA NA NA NA 88 NA NA
    NA NA NA NA NA NA NA NA

    on 103(a):
    0 91 0 92 0 91

    and 99(b):
    85 0 89 0 86

    With the Sac locals come from 99, I think the dish might need to be treaked a little, since from what I read the satellite your locals come from should be in the high 90's to 100. But I haven't had any issues, so I leaving it alone for now.

    The problem is I've been tweaking away like crazy...yes I only use the HR20 signal meter but I'm nowhere near the 90s and only a few people who have posted in this thread have transponders in the 90s (Sacto seems better than the Bay Area though)...I don't know how much more tweaking would help (especially for $75 to have someone come out)...

    Oh how I do understand.
    I'd pick one TP off the Ka SAT that is in the 80s, in the signal meter screen, then peak the AZ, then EL, then back to the AZ and be done.
    I'd doubt D* is limiting the beam so you're at the edge of it, and getting a lower signal.
    How long are your cables?
    How many connectors in the line?
    What kind of cable?

    What is the correlation between a SYSTEM TEST "acquired at %" for each tuner and satellite signal strength?

    How do these two numbers affect the audio and video quality, individually and collectively?

    Cables are only around 20 feet long, the installer only "extended" the pre-5LNB line so there are 2 connecters total, and the kind of cable is whatever D* installs with (around 4 years ago - probably RG-6)...I'm not home to look right now...

    Does the Calamp vs. WNC difference hold any water here?

    I'll try peaking 103b again but that's one method I tried before and I couldn't get anything into the 90s (not even close)...and I've triple-checked that the mast is plumb...so for AZ once the signal is dropping shouldn't that mean to turn the knob the other way and then when it drops again the max is somewhere in the middle, correct?

    My signals are lower today than they have been in the past, but all still acceptable:

    86 91 88 88 83 88 86 88
    85 87 89 86 80 89 na na
    92 na na na na 94 na ha

    We're in the midst of a rain storm here. This is the first real hard rain since my install in late March 2007.

    Running a system test here are the results......

    TUNER 1: OK, acquired at 94%
    TUNER 2: OK, acauired at 73%

    about one hour later......

    TUNER 1: OK, acquired at 61%
    TUNER 2: OK, acquired at 76%

    What is going on with this "acquired at %"? Any ideas? Bad LNB? Bad BBC?

    Here are my signal strength numbers for 103(b) during moderate to heavy rain (compare to numbers in my original post #13, no rain and clear)

    103(b) (16 total)
    1-8 32 47 33 42 33 44 36 40
    9-16 34 42 35 37 28 38 na na
    17-24 36 na na na na 40 na na
    25-32 na na na na na na na na

    Quick check of a few channels showed major pixelation/auido dropouts on the following channels: 79HDN, 501HBOHD, 504HBOWHD, 276NGCHD, 231-1FOODHD.

    Wow...I didn't have a chance to check my signals during the heavy rain today but my numbers during clear weather are almost the same as yours...that is a HUGE drop...up until now I have never had the "rain fade" experience but I have a feeling I will this winter...I know 103b is harder to lock in on but is it also more sensitive to weather too?

    Roseville, CA checking in!

    84-92 on all 103b's TP.

    AT9 Side Car Dish w/ WNC LNB assembly.

    I realigned it myself after the first round of new HD's launched.

    You need an alignment BAD! Those numbers are not going to hold up to a Bay Area winter.

    I'm confused??? Do you have signals in the 30's and 40's on 103b. I'm VERY familiar with San Carlos and you should at least be getting signals from the 70-80 range. I have friends in that area that report "good" signal in the 75-85 range.
