    Is the LNB setting Universal 9750/10600 with 22khz - AUTO or is the LO setting for a single 10600 with 22khz - ON? Either of these two settings will work with an Universal type LNBF.

    The LNBF should not need to be tilted up or down. It should be mounted level and parallel on the support arm. This should aim the feedhorn into the correct area of the reflector.

    What transponder frequency are you using? 12177 is quite strong, but it is also duplicated on several other satellites.

    Is the skew set correctly for 97w?

    Do you know anyone with an FTA setup that you could swap LNBFs on their presumed dish to test yours to confirm operation? I would find another vendor with as many DOAs as you have dealt with!

    You have a triple whammy working against you. 1. Don't know if the dish is even aimed at the satellite. 2. Don't know where to place the LNBF in the sweet focal point. 3. Don't know if the LNBF is working.

    I would first test the LNBF. Second, set the LNBF in the approximate position of the previous feedhorn, set the skew, then only adjust the dish elevation and azimuth until signal quality readings are observed.

    Once you have roughed in the dish aiming, then optimize the LNBF placement and keep adjusting the dish aiming and LNBF positioning. Each setting works against the other. Both have to be exact for the combination of reflector elevation/azimuth setting to be focused in the "sweet spot" for feedhorn placement.

    For a universal lnb, you can use: Lnb standard
    Lo 10600
    22 khz on

    Let me clarify. Im not tilting lnbf, I made the bracket to adjust up and down to find center. The only reference I have to where the old feedhorn was located is the pdf I downloaded that shows how to install original hughes equipment. Every time I adjust I make sure lnbf is parallel w/ support arm, and stand in front to check it is centered.

    I have set skew, azimuth, and elevation for 97w according to my zip code. Post is plumb.

    Don't know any1 else w/ an FTA setup. And yes, im never buying anything else from them again, even if I do get this working. Bought all of this in the same shipment.

    Lnbf is 9750&10600. Honeslty didn't know about the 22k part. But I have been setting LO at 10600. Tried turning on 22k when I got home but still didn't have any luck.

    Thanks again guys

    I would take the LNB support arm as reference and level the LNBF to it.

    The LNBF must be skewed counterclockwise approximately 20 degrees. Once the LNBF is sitting at about the same height and the feedhorn opening is sitting at about the same distance away from the reflector as the previous feedhorn, do not touch the LNBF again until you have located the Signal Quality reading.

    If the LNB LO setting has been at 10600 without the 22khz turned ON and be set to an active transponder, the receiver would be unable to lock on a signal or display a satellite Signal Quality reading.

    Your searching to this point has been for practice only... But the good news is, with all that practice, you should find the satellite quickly!

    Your dish aiming will likely be close to the correct elevation and azimuth, but it is only in the ballpark. Now it is time to aim the dish, not the LNBF...

    You must turn on the 22khz and set LO on your receiver to 10600 (or one of the variations mentioned above).
    This is not an option.
    Then set the receiver for a strong transponder, and start over.
