    I have a 1.2M dish with the sl3 on it. Can someone give me the transponders and sats I need to allign my dish to.

    101 = 99%
    99(c) Transponder 1-16 = 40%-65% (Transponder 12 being the lowest)
    99(s) = Transponder 1-8 = 0%
    15-24 = 0%-21% (Transponder 15 = 19%; 23 = 21%)
    103(s) = Transponder 1-4 = 0%
    15-24 = 16% (Transponder 20 = 16%)
    103(ca) = Transponder 9-24 = 0%-71% (Transponders 9,10,13,14,18,22 are 0%)
    103(cb) = Transponder 1-14 = 35%-64% (Transponder 4 being the lowest)

    Obviously I need some tuning. I just want to know what transponders per sat I should be tuning the dish to.

    You should be able to get mid 80s on most of the TPs on 99c and 103c.
    Since 101 is looking good, you probably have a problem with the skew setting.

    you don't peak to dish for certain transponders, if your dish is aligned properly on the 101, the rest will fall into place

    Since 99 and 103 flank 101 where your numbers are good, I agree with jdspencer that your skew is likely off.

    Where are you ?
    Why do you have this dish instead of a Slimline ?
    In addition to the Skew mentioned already, I would also check the elevation for a minor adjustment.

    I suspect the problem is that the 1.2M dish does not have the correct shape to properly reflect the 99 and 103 signals to the LNB. There is a specific Alaska/Hawaii dish that you would need to use if you must have the larger dish. Where are you located that a regular slimline does not serve the purpose?

    Understand also that the beam width for 99 and 103 is only about 1/2 of what it is for 101. It is possible to have a high reading on 101 and poor readings on 99 and 103 just due to azimuth adjustment. There is a dithering process to follow to properly align the dish, which basically has you note the point where signal starts to drop on each side of the 101 azimuth, and using the "fine tuning" knob count the turns between those points and set it half way between them to make sure you are centered. But that won't work if the shape of the dish is not correct.

    Where are you located? Are you using the Alaska/Hawaii dish or are you trying to use a standard SL3 LNB with a round 1.2m dish?

    I have the alaska dish and the lnb that you need. Good to know about setting the signal to the transponders
