Hey, when I was first installing my WS9036, I was using a Spitfire LNB, and I couldn't get any signal. I switched back to the LNB that came with the dish, and picked signal right up. The design of the Spitfire does not allow for adjustment in terms of the distance from the reflector pan, because the indent on it is the exact size of the bracket holding it. On the original LNB, however, there is room for adjustment, and I was successful when I pushed the LNB all the way towards the dish. I still have to experiment, now that I know signal is there, to switch back to the Spitfire and see what happens. I'm also curious to see what the focal point measurements on my mount will tell...
