Well Carl, one of the reasons is that Freeview power levels in NI, pre DSO, seem woefully low compared to the rest of the UK. All other main transmitters were 10 or 20 kw before switchover, not 2.3/1.6 kw. (800w for Brougher asnd Limivady). For example, Black Hill and Rowridge were both 20kw. Why NI Freeview ERPs are so low is beyond me. Surely, between now and DSO they could increase the power at Divis to at least 5, or maybe 10 kw and add the HD channels between now and October ? Why, as usual, does NI have to wait so long for these advances in broadcast technology to come to the province (the DAB situation and lack of Digital One is another disgrace) ?
Not having Freeview HD is a real pain, especially as we miss out, yet again, on two major sporting events. GRRRRRRRR.
Still, roll on October Carl. I'm counting down the weeks

P.S. 23 isn't great hear either Carl (Jordanstown) but during the high power tests in January signal levels were endstopping, even on 23.I also think the switch to 8k mode whould also improve things.
If you're getting some sort of signal, even if it's breaking up, October should show a massive improvement. I'm highly optomistic about this if the tests in January are anything to go by.

Peter I agree with you 100%. I'm living in Newry and have a TV with built in freeview. I've been scanning since January in the hope of receiving something to no avail.It stops and scans at ch 23 and 33 etc for a few seconds before invariably finding nothing.
I'm stuck with an expensive TV not living up to it's full expectations all because the digital signal level is so low. Why it can't be increased slightly for the Olympics and the Euro's is anyone's guess.
I'm thinking about contacting my local MP to see if he can do anything.
