Same here Jack no lock at all on DB 8000. I have been experimenting with C Band these last days and it's rather confusing to say the least with a 1.5 m Dish.
I can receive from 34.5 W right up to 49E (that's the limit Eastwards the Dish can travel at the moment.)
The funny thing is that at 5W the only TP I can pick up is 3727 R 29950 7/8 and although the signal is not bad (42Snr) the picture is rather erratic.
