Folks,
Well I have got a little further. I am now getting a signal intensity of 90% and a quality in the range 70-80% on most transponders. Trouble is, even though I have this intensity and quality on the 10744/H/22000 it keeps failing to pick up anything on that.

during an auto scan.
I have tried repositioning several times but I only get a signal at this position with either south or north of it. I've also twiddled the LNB angle, all to no avail.
Help!
