Meconi: there was 15 minutes of low signal on the HD multiplex this week, but no other transmission problems.

Can you please see Freeview intermittent interference | ukfree.tv - independent free digital TV advice ?

I live at AB23 8SY postcode, Balmedie. I have had off and on issues since switchover last year. At the moment, built in freeview box in my Panasonic Viera is giving very scrappy results on most channels (Mux 2 and A seem worst) - Mux 1 seems only good selection. Picture improves when I switch to watch via my old Thomson Top UP TV box. I see there was engineering work at Durris at the weekend but if that has now stopped I'm still getting poor results. My external roof mounted aerial is 2004 model (as are all the connectors etc) but I have the feeling that if I spend cash on upgrades I'll still get poor results - should I give up and just get Sky? All the usual factory resets, induction/mobile phone interference checks make no difference. Any thoughts please..?

Graham: Considering the power of the transmitters and the distance from (22mls) I feel that there must be some issue concerning you local terrain that's causing you problems, as although the main BBC1 / ITV1 / HD service is indicated as being good, this is indicated to a lesser extent for the other three Muxes, ArqA/Mux Ch26 indicating variable, and which still remains the case at November 2012, the two other Muxes SDN/Mux Ch23 and ArqB/Mux Ch29 having joined this state in September 2012.

So even although experimenting with aerial positions etc can nearly always bring improvements to most installations, but as the forecast is downwards as far as these three are concerned I wouldn't really hesitate in opting for Freesat, as that mode of reception is about the next best thing to having a wired connection direct to the actual station.

Graham: There are hills to the south-west (in fact, there are hills to the west in general) of Balmedie which do seem to be between you and the Durris transmitter. The trees which are there to provide a sound barrier between Balmedie and the bypass to the west probably aren't helping either.

As jb38 says, the terrain is the likely cause of your problems.

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.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
