AB42 4HQ the only channel we can receive is channel 5, it's not just us but our neighbours are having the same problem. The screen goes blocky and the the message weak signal appears on the screen.

Hilary Walters: There does not appear to be any faults with the Durris transmitter reported. Are you and your neighbours in a block of flats? If so, then there is likely to be a problem with your buildings system.

Peterhead/Strichen area is currently having intermittent signal and loosing channels. 2 properties in Craigewan Crescent, Peterhead (AB42 1HL). 1 in Strichen around Mormond Place (AB43 6TY) all tuned to Durris...

These have now tuned through free sat or sky and cannot use the digital aerial installed.

How many others are affected... getting worse since last 2 days and today....

robert wilson: As far as the problems with reception are concerned. No faults have been posted on the engineering notice board (as yet) concerning transmission failures at the Durris transmitter, nor is any engineering work in progress at the station. However the undermentioned should be noted, as it's very much applicable to the two postal code areas referred to.

Although DUK's reception predictor does show Durris as being the station covering the AB43-6 postal code area, however, it might as well not be!, as only three out of Durris's eight multiplexes are indicated as being receivable in the area, but though with only the BBC's HD mux (C22) in the category of "good", both BBC (C28) & ITV (C25) indicating "poor".

A subsequent terrain check of the area in question revealing that the signal path from Durris suffers from three line-of-sight obstructions starting from approx six miles out, the worst being from three miles out.

AB42-1 has slightly different prediction for reception, insomuch that all Duriss's eight multiplexes are indicated as being receivable, but though with only COM7 HD (C32) in the category of "good", the remainder being "variable", the signal path from Durris suffering from a continuous line-of-sight obstruction from approx five miles out.

Line-of-sight obstructions of this nature always have a much greater affect on reception the closer they are located to the receiving end of the signal path, reception in these areas only being possible in the first place through diffraction (signal bending), something which is less effective if located too close to the obstruction. (the shielding effect)

Another aspect being, that reception under these conditions is more vulnerable to being affected by seasonal changes such as to the surface of the terrain etc. (e.g: summer / winter effect)

The L.O.S obstructions referred to can be seen by opening the undermentioned links, the first two being reception predictions for AB42 and its corresponding terrain. The bottom two being similar but for AB43.

John: The Cullingworth relay is listed with a warning of "possible service interruptions".

If though you are actually meaning that you reside in the Cullingworth area? but are, or (magically!) have been receiving Freeview from the Idle transmitter, then there isn't any problems, as Cullingworth is well outwith the coverage area of the Idle transmitter, and as such, anything that might have been received from Idle is almost guaranteed to be totally erratic.
