The symbol shows the location of the Divis (Northern Ireland) transmitter which serves 440,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Divis (Northern Ireland) mast?

Deirdre: Although what B.Moffatt has said is perfectly correct regarding Oct 24th, however as far as your present reception is concerned the problems you are experiencing are not entirely unexpected when using an aerial of the type described even although you are indicated as being just slightly over 4 miles away from the station, as Film 4 is on the least powered transmitter of the group by only being on 1.6Kw whereas the other transmitters range from 2Kw / 2.3Kw.
By the way from October 24th the BBC / ITV / HD will be on 100Kw and with the three commercial channels being on 50Kw.

I'm currently using an Aerial masthead amp to receive terrestrial broadcasts. I've heard that when the full digital signal is transmitted that these may actually have a negative impact on decent reception.
Can anyone confirm that and would I need to remove the amp. Thanks.

MEM: Regarding the latter not necessarily so! although as you have not provided a post code or one from nearby (a shop etc) an assessment of the signal levels expected in your area cannot be made, but once switch over does takes place should they be found to be slightly too high, the symptoms of being exactly the same as the reverse situation when a signal being received is on the weak side, ie: various fashions of picture break etc, then you have the choice of either removing the amp or alternatively purchasing a simple attenuator costing about £4 or so which is placed in line with the TV or boxes aerial input socket, this in most cases completely curing the problem.
That said, when switch over takes place there are usually always a very small number of people whose signal is right over the top whereby its causing blocking in the TV or boxes tuner resulting in no picture being seen, the test of whether this is applying or not being to temporarily try a set top aerial, as if this works then the main aerials signal requires attenuating, but at this point in time I really wouldn't be too worried about this possible problem.

I took the opportunity last night to do a digital scan whilst the engineering works were being carried out. Frustratingly whilst the scanner hovered over the channels for a good few seconds I failed to pick up a single channel. I don't know if this is anything to worry about or not. Can anyone enlighten me?
I live in the Newry BT35 postcode area.

You'll definitely get Freeview Lite from at least one of the Newry relay stations after Ontober 24th MEM, and possibly the Camlough transmitter as well.
Try Digital UK's postcode checker just to see if there's any possibilty of picking up Divis.
Failing that, there's always Freesat as an option if you don't want to pay Sky.

Thanks Peter I did a detailed postcode check on digital UK and according to that I'll get great reception from the Newry relay.
However it only gave me a score of 67 and 59 respectively for Mux c and d from Divis. I have absolutely no idea what channels are broadcast on these Mux but would a booster give me a better chance of receiving them? Thanks.

Multiplex C are the Sky channels i.e. Sky News, Pick TV, etc. Mux D is ITV 4, Viva, Film 4 etc.
I'd treat those Digital UK postcode predictions with a pinch of salt though. For example, they claim I'm getting variable reception of Mux 1 (BBC 1, BBC 2 etc,) Mux A (ITV 3, Channel 5 +1, 5 USA etc.) and Mux B (News 24, BBC 4 etc.) yet in practice reception is generally fine (with a relatively modest widebant aerial) so you'll never really know until you try.
If Divis doesn't work then the local Freeview Lite combined with Freesat would be just as good as Divis. You're only really missing around 5 channels that aren't on the main Freeview transmitters, and your gaining a lot of others on Freesat that aren't even on Freeview.
Freesat could work out cheaper in the long run than a large aerial for Divis, which can be quite expensive these days.
Don't forget you can install and octo LNB on your dish and have as many as 8 Freesat receivers, 4 PVRs, or any combination in between.

MEM: They gave BBC2 analogue a lovely send-off here in NI. Later with Jools suddenly stopped and it switched to a still caption about the DSO. Then it cut to a clip of the old 80's stripy BBC2 logo which unrolled as the announcer explained that analogue BBC2 was coming to an end after 48 and a half years then BANG out it went!
