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?

D mcphail: There are no faults showing for Durris. Have you checked for any loose or damaged cables or connections behind your TV? Please provide a full postcode so that we can see where you are in relation to the transmitter and your predicted signal strength etc.

Me again(from June) AB24 2BE ,today engineers were at the 4g mast closest to my house(20/30 yards away) built last year & my tv aerial is working perfectly again or probably till they've finished turn it back on.
I 've tried a 4g filter & new booster with 4g filter built in with no joy when the mast is on,any advice?

Peterhead

Is there anyone in the Peterhead area who uses Durris for Freeview? My mum got a 12V masthead aerial installed on the roof recently and the reception on all channels is absolutely perfect, except for pixelation and drop-out which occurs every 9.8 seconds exactly.
If I had to guess, I would say we are getting interference from RRH Buchan which would be roughly in the line of sight, but I find it amazing that the installer wouldn't have been aware of this possibility (if this indeed is the cause, its my first assumption given the clockwork regularity of the interference).
Does anyone use Durris in the Peterhead area and have had to deal with this specific form of interference? Is there a specific filter type which could strip out the actual unwanted RF?

You need to check what the signal satrength is being reported on her TV set is. Too strong or too weak signals can give the weffect your are reporting. The post code you gave is just 1 km from the transmitter and it is highly likely that she has too much signal now. That can be reduced using coaxial attenuators (available quite cheaply from Amazon and others) inserted into the aerial feed. Do not allow the weight of the attenuator to 'hang' on the aerial input socket of the TV, use a short flylead between the attenuator and the set.

Thanks for the reply, I have already tried attenuating the signal so the signal strength is around a static 60% (on the TV meters). The signal quality is 100% but drops to zero for a fraction of a second every 9.8 seconds. This periodicity is the same on two different television sets. Reception is perfect on all channels apart from this periodic fraction of a second.
The transmitter the aerial is pointing at (Durris) is over 50km to the south west (with a radar station RRH Buchan roughly in line of sight),and the local Freeview-lite transmitter is 1km away to the north west.

I suspect, then, that you are suffering from periodic interference. Nothing in a TV or a TV transmission would caise something to affect your reception every 9.8 seconds. As it also appears on a second TV set then you will have to investigate where the source is. It will have to be something with a regular pattern to what it does or how it works. What it might be we cannot tell remotely.

Hello, can I just ask if there are any problems with the Durris transmitter today 13-04-18? I have lost BBC1 & presumably the other associated channels on that frequency (?) ITV1 works but is a bit 'blocky'! I guess while I am at it, can I ask if I will ever get BBC4 HD back? I lost it after l presume a recent change? I am at AB157SF. Many thanks, G.

G. Nicol: There are no faults showing and the Digital UK checker predicts that you should have a good signal at your location. The most likely explanation for your problem is a fault/damage to your aerial system somewhere, so start by checking for any loose or damaged cables or connections behind your TV then work your way back towards the aerial (as far as you can safely access).

Your comment please
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.
