I have 1.3m dish and a Technomate TM-2200 motor attached to a TM-6800HD Super
During the recent gales my dish rotated on its bracket and I had to realign it.
In the process of retuning I found that I "lost" a number of the weaker TPs on 28.2 - the whole signal strength had dropped by 10-15% and almost everything on Nile 7W.
This confused me since I thought I'd aligned with Thor approximately due South !!!!
Tried again today by realigning the whole orientation of the dish and managed to get most things
back.
Can anyone advise me why this should be...is it to do with the tilt as the dish rotates and the angle (rotation polarity) of the LNB ?
How critical is the the dish points due South ?
How critical is the rotation angle of the LNB ?

How critical is the the dish points due South ? - if not then you have to change the displacement of the satellites, and then it wont work because the arc that the motor moves in is no longer accurate

How critical is the rotation angle of the LNB ? = not as sensitive as dish pointing south, but also has an effect

In summary - get it right or struggle with some or all satellites
 
I'm finding the satellites OK but I wasn't getting the signal strength on some TPs. e.g. all Hotbird TPs were vewry strong but I lost a number of Astra 2s
What is the criticality of this setting ?
Is using Thor as a reference point good enough. i.e. with the motor set to "0" ?
BTW I am tuning the satellites manually rather than using any GoTo function (& this motor doesn't have USALS)
 
Do need to "tune" the LNB when I'm set towards my weakest signals e.g Nilesat TP = 11938V ?

You could do very fine adjustments on a weak signal, the LNB to be vertical is if your location is at 0 deg. longitude
