Kieren: I haven't experienced any problems when I have been using Freeview HD from Sandy, and what you mention is inclined to suggest that although you might have been receiving HD OK it was possibly at a level not far above your boxes receiving threshold, and which it may now have dropped under due to atmospheric condition changes.

As you have re-set your TV (or box) you will have blanked out the stored channels memory, so go into the tuning menu and check the signal strength on Mux Ch21, that being Sandy's HD Mux transmitter channel, and if you get about 40% or so level showing try a manual tune, storing as necessary, unless done automatically on your device.

Thanks for the link Mike, very useful.

Kieren - HD all ok here, I'm in Stevenage.

I hate perfect signal on all digital channels before switchover, since switchover a few channels keep breaking up. Thought the retune last week would have fixed this but still can't get ITV4 clear.

Kieren: I live in Harlow, another fringe area for Sandy Heath. My HD is excellent but there appears to be something strange about SDN/CH31 since the 31/08/11 switch. It is now missing from both my boxes. I have connected a signal strength meter and both Arq A and Arq B pumping out 20Kw come through as 40% signal & 65% quality. SDN allegedly broadcasting at the same power only registers intermittently, not sure technically why that should be. Before the changeover SDN, Arq A & B were Ok. The postcode predictor give Sdn as poor.

Mary Nolan: On your remote control press "services-4-6" and note what the strength / quality indications are showing as, they should be about 75% along the scale with both about even with each other. (or very near anyway)

If they are not, then your dish is liable to be slightly out of alignment.

Neil: ITV4 etc is on a much lower powered Mux transmitter until 14th of this month when a further re-tune will be required, as it then changes from Mux Ch67 to Mux Ch48.

Doug B: You are possibly suffering from the reverse of many experiencing problems with HD from Crystal Palace on Mux Ch31, this because of Sandy also using that frequency on a temporary basis until May of next year.

In other words Crystal Palace HD is likely to be affecting your reception from Sandy.

Doug B: C31 is used at Crystal Palace for the HD Mux. It is likely that signals for SDN from Sandy Heath and HD from C.P. are blocking each other at your location. What did the Digital UK postcode checker give you for reception of Crystal Palace?
