I'm located in South Lancashire, and I could pick up 30W with quite strong signals my old 80cm dish.
A tip for recieving 30W is wait for a sunny day, and aim your dish towards the sun at around 3.00pm (BST), your dish will then be facing 30W. The elevation of the dish then needs adjusting - at this time of year (summer), the sun is above the satellites.
Also, to improve the signal, rotate the lnb slightly anti-clockwise as you look at the dish.
I did find it quite difficult to align to at first, but now I use discovered a tree (in the far distance), that is directly in line with 30W from my dish. Now I can usually find it quite quickly.
I don't think that its generally considered that hard, although I have read that many people seem to have problems with these satellites. When 1C & 1D were launched, the signal became considerabley stronger, making alignment much easier.

Sometimes that happens when there's nothing coming through on a transponder. Could be dead or a feed when it's needed. You need to establish which channels are available to YOU and then make sure you have a good signal on those.
