The three strongest satellites are:
Hotbird 13 @ 13 deg E of S,
Astra 19 @ 19 deg E of S and
Astra 28 @ 13 deg E of S. (mainly English and Sky) some signals are carried on a Eurobird satellite on effectively the same bearing
If you only want English channels you are probably best starting at E and bearing south slowly.
Some will note that I have used the practice of using the bearing rather than the satellite designation after the satellite name, this seems to be the favoured method now and saves a lot of confusion as not all the satellites named (for example) Astra 1x are on 19 deg E of S.
Some kits already have the satellites loaded, if yours is not it is worth loading the above 3 satellites as this will ensure you get the right one next time - set all the kit up on say BBC2 Engand and just wait for the signal to come in.
As far as I am aware all of the satellite bearings will contain analogue and digital transmissions, the satellite finder is just indicating that there is a signal present and can not differentiate between the two types of signal.
