OK, if we just can get the C/N values at your location we can tell how far away you are from even receiving any signal.
These C/N values are needed to get a signal lock at these FEC:
FEC C/N
1/2 4.1dB
2/3 5.9dB
3/4 6.9dB
5/6 7.9dB
7/8 8.5dB
You can push the C/N limits a bit down further if you have a really sensitive receiver, maybe 0.5-0.8dB down or so.....
After looking at Lyngsat i can see that BBC on 2D uses FEC of 5/6 which means you need a pretty high C/N to even get a signal lock, eg 7.9dB
Just get the C/N for your site location, it's much easier than to speculate all the time.
Please take a note and maximize the dish on Hotbird or something that you know have great coverage at your location and then measure the C/N, that way we can know how your dish setup is performing.

Next time we try again I will get some pictures of the log from the Spectrum analyzer so we can see the signal levels in C/N( what does it mean C/N just to be sure?) and I will tell you what Spectrum analyzer we use.
I think this is all for now
