I just picked up a Technika STBHDH2010 Freeview HD Digital Set Top Box for 30 quid from Tescos. Thought this was an amazing bargain, but since I've set it up, I haven't been able to pick up any HD channels, which was the whole point of the purchase. I live in North London (NW10) - so it seems that I would be receiving transmissions from Crystal Palace, which I've now discovered is on low HD output until full switchover. But when I input my postcode in the Freeview HD availability checker it said I would be able to get HD reception. So is that it? I have to wait now until April next year? Or if I sort my aerial out will I get proper HD reception? Is anyone else having this problem?
