Detailed comparison Freeview/Sky

Terry: This type of problem suggests that the dish in house B is slightly out of alignment, you should go into the signal test screen by pressing "services - 4 - 6" and check if the strength and quality are level pegging at around 60%+, because if the quality is lagging then the dish requires slight realignment, this usually always being in the horizontal (left / right) plane.

By the way, if you tested the old Pace box out on house A's dish you would possibly find that its perfectly OK.

Patricia Boothman: If you are receiving your signal from the local Ramsbottom transmitter located at just over 1 mile away, then no faults have been reported as yet, although this does not necessarily indicate that there isn't any, especially if it involves failure of the electricity supply to the station.

Your best policy would be to make an enquiry with a neighbour to find out if they are being similarly affected, that is if they are also using the Ramsbottom transmitter, a way to tell being if the elements on their aerial are seen to be vertically mounted and "not" horizontal.

Mike Tasker : For what its worth, reception of Sutton Coldfields COM7 (Mux C33) is indicated on DUK's site as only providing a variable level reception in the Enderby area, whereas on the other hand Waltham (Mux Ch31) is indicated as providing an excellent signal, both stations indicated as being line-of-sight as far as the terrain is concerned, this excluding any man made objects or vegetation such as trees.

Your problem could simply be that the signal level received on Mux 33 is running at near to the critical level for reception, glitching etc being commonly experienced in this type of situation.

Mike Tasker : In addition to that said, although in the interests of accuracy knowledge of the area you reside in (post code or one from nearby, e.g: Post office / shop) would have been of assistance, however, on having carried out a few rooftop checks in various locations around Enderby the majority of aerials were seen to be facing in a North Easterly direction towards the Waltham transmitter.

Peter Young: Although in some cases reception problems of the type you are experiencing can be overcome with the addition of a variable gain booster, however, this is totally dependant on the technical nature of the signal being received, insomuch is both the strength and quality of the signal fluctuating? or is the signal strength reasonably constant but the quality is observed to dive up and down? a booster "not" helping in this latter case.

Therefore you should carry out a signal check on the BBC, viewing the level indications for at least a minute or so and noting that seen, then for comparison purposes, carry out the same check on ITV

Further advice dependant on results.

Peter Young: In addition to that said, prior to replying I had checked the reception situation in your area using Megalithia's "land only" terrain indicator, this revealing that the signal from Hannington is obstructed at approx 3 miles prior to your location and not just by the sizeable range of trees on the Northern side of the estate.

The point being, that even although your reception might well have been fine in recent years, its possible that the signal level received could have been dropping off slightly though time for a variety of reasons, such as increased growth / density of tree foliage, moisture content also playing a role.

It would also be interesting to find out if anyone else in your area is also suffering a similar problem with their reception of the BBC channels.

John Martin: Although you are in an almost perfect location for the reception of Waltham or Belmont via each end of the aerial, however due to the nature of the terrain between Waltham and Denton the signal from that transmitter can be iffy in various places around the Denton area due to being partially (or sometimes fully) obstructed by the terrain, a problem that even applies to certain parts of Grantham and why a number of viewers use Belmont for Reception rather than Waltham. If the problem referred to persists, then you may find it advantageous to turn your aerial around to face Belmont for maximum efficiency, that is"if" its presently facing Waltham?

martssmart: If the aerial socket in your flat is connected into a communal aerial distribution system?, then the problem might possibly be due to the power supply to the distribution amplifier having been accidentally connected into the time switch used to control the on / off times of the landing or passageway lights.

pat: I would try carrying out a manufacturers reset on your TV or box prior to retuning same, this procedure also known as a "default setting" or "first time installation".

Peter Young : Ref: MikeP's posting, although that said by same when referring to my reply is indeed correct, however the reason why I did not specifically include Rowridge as a possible alternative for reception to Hannington is for the following reasons.

(1) All aerials seen in your area are observed to be pointing towards Hannington, no exceptions having been found.

(2) Checks made using DUK's reception predictor for your location indicates "iffy" (officially variable!) reception from Rowridge on all muxes with the exception of BBC A / D3&4 and BBC B, the possible reason for this being somewhat backed up by the terrain indicator revealing that the signal from Rowridge suffers from an obstruction of a sizeable nature at about 2.5 miles prior to your location.

Although the reception predictors indications have always to be taken with the proverbial "pinch of salt", but when this is coupled to that seen on the terrain indicator then DUK's forecast cannot be completely disregarded.
