    I've heard that I can convert my old analogue satellite dish (which I use to watch foreign football matches mainly) to digital by replacing the LNB with a digital one. I know I have to get a digital box also, but is this possiblle and is it easy to do? Any tips would be very much appreciated.

    Depends how old it is and the spec. If you have a Universal LNB then there is nothing to change, there is no such thing as a digital LNB. The reason most SKY analogue customers had a new LNB (aside from needing to match the minidish) was that the older LNB's were standard or enhanced models with limited reception range.

    I think, people with more experience with them can probably explain it better:)

    There is actually no such thing as a "digital LNB" (or LNBF , meaning integral feedhorn).
    However, best performance on digital signals is acheived with low phase noise and oscillator drift - which LNBs more than 8 years old are unlikely to exhibit.
    For the highish symbol rates used by Sky and other multiplexes this doesn't actually matter much.
    It does matter for low symbol rate single channel transmissions - like many "feeds" or OB links which are usually SCPC (Single Channel Per Carrier) with SRs often at 5632 or 6111 or similar.
    A really good test for steerable FTA systems at present is the Sicilia Channel on NSS7 at 21 degrees west with symbol rate of 1028 and FEC of 7/8 (so not much error correction either).
    Full tuning parameters : 11634H, 1028, 7/8, 2360/2320.

    Can't help the language flow - I'm a techie working for a USA semiconductor company. I am paid to be an anorak !

    Basically anything sold as a universal LNB should do the job .

    Verstehen ?

    That means "to understand".
    The phrase you want is "alles klar?". It means literally "everything clear?" but colloquially it's used as "OK, understood?" Use that phrase in Germany and they'll slap you on the back and buy you a Bier. ;)

    (I think I'm turning into an anorak, too! Must be old age).

    When I was in Germany, I found I only needed two phrases :

    "Eine bier bitte" and "pom frits mit ketchup, bitte" (sorry if the spelling's wrong !) :)

    I used both phrases when in Germany myself in the mid 1970's.
    (Lower Saxony / Niedersachsen) .

    Often got "forced" into imbibing the local korn or schnapps as well :)
