Back in November (I think) I posted a note saying I was stumped in getting Ku to work on my BUD. (10 ft. Winegard, General Instruments receiver, C & Ku dual feed horn, 24 inch actuator arm, new Astrotel pmj-lnb Ku LNB, older C band LNB.) C band was perfect, no K band. I got a lot of advice on dish alignment from here and other places but no success. Finally I decided that if the dish needed aligned any better that nobody could use Ku band because it was too sensitive. Therefore it must be equipment. I replaced the Astrotel Ku LNB with a Norsat 4206A. Now I can get all of the channels on X4 with a signal of 84 to 88 and a quality of 93 to 99, some feeds on X0, and the two digital channels on K3. I just wanted to tell you guys that sometimes it isn't alignment, it's equipment. The new Astrotel LNB was just defective. Now that I have it working I can see that the alignment is more sensitive than C band but there is a fair amount of room to move the dish and still get a good signal.
