Hi - I have two sky decoders (one at my house and the other at a holiday home) I used to be able to use the sky card in both decoders without any problems.
However I now experience rain fade with the older decoder (both are motorola) I phoned sky and they said my dish may be out of alignment. However I brought the other decoder over to my holiday home and its works perfectly.
So it must be a setting in the older decoder - has there been a software upgrade or something.
I checked both settings (ie satelite and LNB setup) and both decoders are the same
