Hi Nigel,  I have a one metre dish that I installed my self.  It works fine for all the channels (except five and related channels).  On the sky signal test it shows signal strength about three quarters and quality about half.  When its windy or heavy rain this varies although rarely affects reception.  The thing is some times, and I don't check that often I get a picture on channel five. Its usually blocky with broken sound and after a while it reverts to the sky no signal screen. Does this mean the after the change over it might be possible to fiddle about with my dish to get a better signal and possibly get the channels I want.
I don't know much about the technology involved in all this, and I have researched on the internet but there seem to be many different views, from we are all doomed to there will be no change.  Does your 1.9 dish point the same way that our dishes point now.
Thanks Bill
