Sandro: The Freeview HD website only tells you if HD is available from some transmitter in your vicinity, not necessarily the one you're using.
The best bet at the moment is the Sandy Heath transmitter, where HD services started at stage 2 of Digital Switch-Over, on the 13th of April.
The only other nearby transmitter broadcasting HD is Crystal Palace, for which the prediction is poor.
Hemel Hempstead won't start broadcasting HD until step 2 of its switchover, on 18 April 2012.
Sandy Heath should be good for all multiplexes now, though the predictor does show a probable deterioration on ArqA and ArqB multiplexes late next year (not clear why). The aerial needs to be oriented horizontally rather than vertically, and you'll get East Anglia news and other regional programmes rather than London. The predictions are more stable if you stick with Hemel Hempstead.

Hi, I've got a roof aerial, and I'm 7 miles (according to this website) from the Hemel transmitter. At the moment, signal quality is 10/10, and normally BBC1 has a strength of around 8/10. However sometimes this drops to 4 or 5/10 and pixelation / picture break up occurs. Why does the strength vary so much and after switch over will I still have the same problem or will the digital signal be boosted? Thanks Paul

Paul: Can you please see Freeview intermittent interference | ukfree.tv - independent free digital TV advice ?
Your problem could be that your signal is too strong. If you have a booster or amplifier, try removing it from your system.

Retune required!

Brianist: Like Alastair, since Wednesday lunch time, I found that all BBC channels (except BBC4) are 'no signal', as are about another 10 channels -- on the digitial box that has been working well for 6 years. Must I really do a 'first time install' to make it work again? Is that different from retuning?
