I finnaly got the time to get back to fine tunning this system ( same as above ), after dialing my true south and i do believe i have it nailed down ,i'm able to get a strong signal from 72 AMC6 threw 101 AMC4 but any sats above 101 i am unable to get any signal . I am using USUALS for the motor and i tried to fine tune useing Diseqc 1.2 tweaking a little west and east with no luck . Could it be i need to adjust the declination angle on the dish ? Bottom line the firthur west i go the less the signal . ;} just a note i'm scanning these birds only on the L side of the lnb set to 10750
EDIT: Panhandler, I see you posted before I finished my post below. Even though you appear to have resolved your alignment issue, please read what I mention as I do believe it will help you avoid some issues.
Panhandler,
Since 79W is the truest south satellite for your longitude position, you would peak the signal on that satellite by adjusting the dish elevation and the motor azimuth (don't move the motor latitude, that should remain fixed).
Then motor over to some sat either west or east of 79W and adjust the motor azimuth to peak the signal. Preferrably a sat that is as far away from 79 as you can go while still maintaining a signal.
Then motor back to 79W and fine adjust the dish elevation.
If you have done this and you are not following the entire arc, then I propose that your mast is not perfectly plumb or your dish is not centered on the motor tube precisely along the motor tube axis.
When you check the plumb of the mast, make sure you check it east to west as well as north to south.
For the attachment of the dish to the motor tube, the vertical axis of the dish must be in line with the vertical axis of the motor tube. There is usually some slop here and you want to ensure that you center this as best that you are able.
Some dish assemblies have a clamping mechanism to attach it to the motor tube in the same manner as the motor is attached to the mast. With this style of dish, you can position the dish on the motor tube anywhere so you you have to be very careful here.
With a dish like mine, a Winegard DS-2076, there is a bolt that goes through the motor tube to help align it. However, there is some slop here and that slop will create some errors in both the elevation and azimuth.
Also, make sure that the assembly bracket where you make your dish elevation adjustments remains square. When you loosen the hardware to make an elevation adjustment, the weight of the dish can "twist" or pull the bracket off to one side and induce both an elevation and an azimuth error as well.
These three items that I mention should be scrutinized during the entire alignment process and maintained for their accuracy of plumb and square.
Your results suggest that one or more of these items may be inducing errors for you.
