Why is Carnmoney not getting the same number of DTV channels as Divis? Are there future plans beyond 24th October 2012?

Tim: No, Carnmoney will remain "Freeview Lite". This is because the Commercial broadcasters (those that won't be transmitting from Carnmoney Hill) don't consider the expense worthy of the return.

The achieve 90% coverage of the population from 81 of the largest transmitters (largest by viewer population). There are over 1,000 small relays like Carnmoney and these serve about 8.5% of the population. The cost to the Commercial broadcasters to transmit from these relays would roughly double their cost of transmission and this, they decided, isn't worth it.

Tim: Carnmoney Hill will broadcast RT and TG4 for which you will need a Freeview HD receiver.

Thanks, Dave and Peter. I chatted to Digital UK and they say that things might change for my location during switch-over as Divis' transmission power is to be boosted by 10 times. This morning, I was certainly picking-up the same BBC DTV channels from two different muxes. Here's hoping!

Tim: Transmission power from Divis went up from 2.3kW to 100kW on the BBC SD channels this morning, which is 43 times yesterday. If you are getting two BBC muxes check their frequencies, Divis BBCA is E27. Carnmoney is E46. If Divis is good get a new aerial.

Tim: It also depends on your location.

In and around Kings Park Divis reception appears to be fine, post DSO, along with the NI mux from Black Mountain, according to Digital UK's postcode checker. Along the Dough Road it would appear to be very poor, and doesn't improve until you get up as far as the Manse Road, so you never know until you try.

I'm in Jordanstown and the BBC A multiplex is excellent after the power increase yesterday. I'm also receiving Carnmoney Hill off an RTE aerial (Clermont Cairn) at reasonably good strength, despite analogue reception being poor.

Then again, I can see the Carnmoney Hill transmitter from my bedroom window !

P.S. Divis would also appear to be O.K. down around the Abbot's Cross area and Rathcool, post D.S.O.

I am in Kings Road, newtownabbey. I retuned my digital TV on the 10th and all was fine, am getting good picture on BBC channels. Last night 11th Oct a few time when I switched the TV from Analogue (was watching ITV) back to digital I got no signal message and had to re tune every time to get the channels back. Is this normal.
