I am sure it was 10000Mhz or 96?? or something like that for old analogue transmissions of 20 years ago > > 2) the "new" universal one, with seems to be used by most modern > satellite dishes in Europe nowadays: > > EXTENDED > Astra 1E, European Universal Ku (extended) This needs renaming as 1E has long gone. Certainly this type is used for Astra 19.2 and 28.2. Ideally we should use a default LNB type for each Satellite either in libdvbv5, Kaffeine or respective tables. Regards Malcolm
