Things have gone peculiar on our dvb. We record on dvb on Scart 2, this morning Scart one and two say "no signal", for the one and only time in 3 years. Why

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.
