Since last reporting on 1/8 I decided to dismantle the 45cm Sky dish and LNB I was using and chucked them. I bought a 48cm freesat dish totally adjustable and put my spare 40mm LNB on.
I have now got a far better signal and can pick up BBC2 and a whole lot more again now!
However, the main channels I still can't get are all the CBS channels, Horror, Bet, True Ent, S4C2, Euronews, Bloomberg TV, CNBC, True Moveies 1 & 2, Movies 4 Men 1 & 2 plus a few others I am not too bothered about.
Is this due to the fact that the dish might not be fully aligned yet or all down to the CBS channel issues raised earlier? The Bush HD box does seem to be working ok.
