The symbol shows the location of the Durris (Aberdeenshire, Scotland) transmitter which serves 180,000 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 Durris (Aberdeenshire, Scotland) mast?

I have either data service or a badly pixelated picture with no sound on most of my channels except itv 1 & 2, c4 & c5. sky news says weak or no signal. I had a brand new ariel fitted on Wednesday at a cost of £165. Its in the loft. Do I need to get the guy back to put it on the roof or is this just a hazard of bad weather it is fairly windy. thanks for your help.

Frances: You should have perfect reception, so yes, the aerial should be on the roof.

We live in Milltimber, about 8 miles NE of the Durris mast and in clear, uninterrupted line of sight. The digital BBC programmes on the family room TV are all scrambled into channels in the 800s (eg. BBC1 = 815, BBC2 = 818, CBBC = 821, etc), whereas on our sitting room TV, which shares the same aerial in the loft, they're all normal, as is Mum's TV in the annexe (separate aerial).

The family room TV used to be in the sitting room and worked normally there, as did the previous TV with digibox in the family room for a while until about the time of the final analogue switch-off. Can you explain this and suggest a solution?

Not only have we reset the digibox Freeview tuning repeatedly, but we even bought a new one, with the same result. We've learned to live with it, though it is very confusing for guests and questionable for grandchildren looking for CBBC in proximity to the adult channels!

Diana Daly: Finding services in the 800s is usually as a result of more than one transmitter being picked up. So BBC One from one transmitter will go in number 1 and the other will be put in the 800s. However, (based on the output of Digital UK predictor), I'm not convinced that this is the case here.

The most striking thing is the close proximity to the transmitter. The poor reception on BBC might be as a result of too much signal. See here for an explanation:

Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice

Try using the other aerial. Having got the TV/box tuned in correctly, if you connect it up to the other aerial and find reception is poor, don't retune because this proves that it is an aerial problem. By problem I suggest that it is too higher signal level, and therefore requires attenuation.

You say that the family room and sitting room use the same aerial. If the signal is split with a powered booster/amplifier, replace it with an unpowered splitter.

An amplifier makes the signal bigger, whereas an attenuator makes it smaller. There's little point in having both because one acts to cancel the other out. You may find that an unpowered splitter brings the signal level down far enough to be within that which your TV/box will function satisfactorily.

We live in the Bridge of Don and have been experiencing reception problems for some weeks now. I have upgraded the aerial and replaced the signal booster. I have checked the signal before & after going through the signal booster and get 60% & 70% respectively. I now realise that there is ongoing work at the durris transmitter, how long are there going to be interruptions to the transmissions?

We live in Inverurie AB51 5QX. The aerial is on the roof yet we do not appear to be getting any channels in HD. The aerial is set to Durris.

Re my post of 26th March. The television is an HD set, it is also connected to a Humax 9300. Neither the Sony HD TV or the Humax box find any of the HD channels - i.e. BBC1 on 50 etc.

Alex Smith: The Humax PVR-9300T is SD only. It has an HDMI output, but this is to make it easier to connect to newer TVs that don't have as many SCART sockets - it simply upscales the content.

The TV may not be compatible either. It has to support DVB-T2, not just DVB-T. "HD Ready" just means that it has enough pixels to display HD content from another source, and a supported way of connecting to that source.

I'd consider replacing the Humax PVR with an HD PVR. Look for the Freeview HD logo.
