Aiming Dish for Sat 119* when other Sats are Good

    I'm having troubles (771's) trying to access any of the Local HD Stations.
    I have a HR44-500 and a Slimline-5SWM.
    Is there a special trick to aiming the Slimline-5SWM dish for Sat 119* (signal strengths 50-70) when I already have good signal on all other Sats (signal strengths 85-100)??
    When I "Redo the Dish Setup" at the "Verify Installation" step it shows Red "X" for Sat 119* for both "Odd" and "Even".
    I also note that the Signal Strength for the "SWM" Sat instance shows low (60 ot zero) for the 2nd "Transponder" but 100's for all others. Is this related ??

    it can be a mast not properly level of something blocking LOS to the 119. and very rarely a bad LNB

    If 119 LOS is clear, the mast is plumb, 101 is dialed in correctly, and dish "tilt" is set correct for your location, the LNB could be bad if levels are still low.

    Pay no attention to the "0" reading on the SWiM signal strength screen. The 0 simply indicates that SWiM channel is in use by a tuner on another receiver.

    I believe the Dish is pointed correctly, given the majority of 95-100 Signal Strength scores for all other Sats.

    I have a tall but thinly branched PaloVerde tree in neighbor's yard which might be encroaching on Line Of Sight, but only to the west of my N-S fenceline.
    The Dish is pointed a bit East of South (AZ 149* El 49* Tilt 106*), and there are none of the 5 LNB on the side of the Head which would point W of Centerline of the Dish, so it seems unlikely that those branches are zero-ing out my Sat 109* reception. Doesn't it ??

    If I do have to refine the aim of the Dish, how do I do it such that I don't lose the high scores on all the other Sats ??

    But refining or fine tuning the aim of the dish is really only necessary for peaking the Ka band at 99 ad 103. .

    119 is Ku band and should just fall in with a coarse adjustment setting to the tilt after 101 is dialed in correctly with only coarse adjustments necessary for it as well, assuming the LNB is good and the mast plumb of course.

    None of your local HD stations come from 119, they come from either 99 or 103. However, if 119 is not aligned properly, it is possible 99 and/or 103 are not either.
    Post your signal strength readings for all transponders on all satellites in the following format:
    Sat 101
    1-8: xx xx xx xx xx xx xx xx
    9-16: xx xx xx xx xx xx xx xx
    17-24: xx xx xx xx xx xx xx xx
    25-32: xx xx xx xx xx xx xx xx
    where xx is either the signal strength or N/A.

    And repeat for each of the satellites - 99s, 99c, 103s, 103ca, 103cb, 110 and 119. Note that 99s and 103s will be very slow to fill in, and many/most could be low or zero (but at least one should be high).

    That will give us a much better idea of what your alignment looks like.

    If you have very good signals on all the 101 transponders, then you may just need to do the fine tuning, or "dithering" to bring in 99 and 103. 110 isn't used at all anymore, and 119 is primarily for foreign language (Spanish), and some local SD stations.

    And remember for your location a tilt of 106 degrees, actually means a tilt a 16 degrees counter-clockwise from completely level (which is 90 degrees) when viewing behind the dish.

    Something is either blocking your dish's view of 119ºW, or you've got a dish LNB problem. Do all of your Receivers show this same problem?

    OK, I described the surroundings of my Dish. Which direction from the Center-Line of the Dish would be the Sat 119 ?? Which LNB on the 5-LNB-SWM head ??

    From behind the dish the 119 feedhorn is the one all the way to your left;

    But it receives off axis from 18 degrees west of where the 101 (actually 99, 101, and 103 feedhorns grouped together) feedhorn is pointing which is the larger oval shaped eye furthest to the right, again from behind the dish.

    Arghh... So, 119 is likely effected by the neighbor's tree. It's going to be fun talking to the neighbot that just moved in this past Spring about lopping part off a tree planted by their predecessor's predecessor.

    Beyond that, does anything in my Signal Strengths indicate why I'd not receive any of my Local HD Stations ??

    Your signal strengths do not suggest what might be the problem with you not getting some HD stations (which you mentioned in your original post). Your signal strengths are sufficient that those should be working. "Suburbs of Central AZ" suggest the Phoenix market. If that is true, then your SD locals are on 101 and your HD locals are on 103S TP15, 23 and 24, all of which you have 100 signal on.

    I'm inclined at this point to suspect a defective LNB. And 119 pretty much doesn't have anything to do with your reception (but needs to be working for some guide data).

    One thing to do though is to re-authorize your Genie (you can do that online or by calling a CSR). If you have recently moved from a different market, you need to make sure that DirecTV sets your account correctly for the Phoenix market, as you cannot get locals from a different market (technical and terms of service reasons).

    TS described it as a SWiM LNB in the first post, so it shouldn't ever need the mirrored guide data on 119.

    Good point, thanks. Still looks to be an LNB problem though. Any other ideas?

    Can this TS change to the Slimline 3 SWM and cure his problem or would that cause another problem ?

    Should be able to, unless there is something on 119 the TS wants or is a part of his package.

    Could be the tree or like you suggest. just a bad LNBF, for the 119 receive circuitry at least.

    Though first I would like to know how any other boxes are receiving 119.

    NO, SWM LNB is selected by the receiver automatically
