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?

aeriel updated on roof. Was receiving HD tv until earlier this year and now have lost all HD channels and various others like ITV4 which I was receiving without issue. Mightily hacked off as have HD equipment which is now worthless. Why do I pay licence fee again as I think we had better picture quality and reception before digi? AAAArgh!

EDz: Have you carried out a signal strength / quality check on Mux Ch22? that being the HD service from Durris @ 17mls, as the signal may well still be there but just dropped under the reception threshold of your equipment.

Also have a look up at your aerial to make sure that it hasn't turned around slightly during windy weather conditions.

ITV4 etc operates on half the power of the main stations, and so will suffer more easily to any aerial problems should they exist.

Ah,Durris another all group A transmitter,that hopefully will remain as such.So to anyone on this transmitter (horizontally polarised) who wants to replace their aerial with a new group W wideband aerial in the poorest or marginal area on Durris,do not bother because yer wasting yer time and yer money.You only need a group A aerial (either Yagi 18A,or XB16A for external antennas,or an XB10A for internal loft antennas) within the poor reception or marginal area i earlier described,only perhaps in a good to medium reception area within Durris (the main mast that is,not its dependent relays) you may use a Log Periodic which is a group W wideband aerial but only i stress in good to medium reception areas within Durris itself.

Can you please advise. AB15 9SE - Village Mews - have have been experiencing "no signal" status intermittently (but for long periods) for the past week or so. Those with Sky are OK. Is there any works being carried out at the Durris transmitter that would be causing this? Many thanks

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.
