The symbol shows the location of the Ridge Hill (County of Herefordshire, England) transmitter which serves 270,000 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.

This transmitter has no current reported problems

The BBC and Digital UK report there are no faults or engineering work on the Ridge Hill (County of Herefordshire, England) transmitter.

Dave Lindsay: Looking at that plot, I'm also wondering why a booster would be needed! Or possibly even an aerial...


Keith Blackham: Remember that the Ridge Hill transmitter covers a large number of homes, so its not unusual to have several people complaining of poor reception.Even if 99.9 percent of people in an area have perfect reception, there will always be some people with a problem. But in the case of both you and Keith Adams, its far more likely to be issues with your system, rather than the transmitter.

Could you check which transmitter your actually on, and what mux's your getting. It might be that your picking up a transmitter much further away, especially if you've got a booster.

Thank you for your interest. There are 3 CTVS affected. The CTV I am sat in front of is self tuned to channel 26 - West Midlands signal strength 29% quality 1%. The aerial is pointing 220 degress ie 180 degrees from Sutton Coldfield - West Mids. All neighbours aerials have always pointed towards 220 degrees. In the past however have sometimes been supplied with programmes and news from Bristol or London??? However signal has always been good in this locality. Bromsgrove transmitter - a repeater is 1 mile across the fields but not regarded as an option for my address. Have always used a signal booster in the loft taking a feed from an external aerial with a horizontal V shaped reflector. Do you have any helpful thoughts?

King regards

keith Blackham : If, as you have said, others in your area are also experiencing similar problems with reception then the reason for is obviously outwith your control, that is unless an alternative station is found as providing a more stable signal.

As far as your aerials direction is concerned, a rooftop aerial check (via Google) in your area indicates aerials as being vertically mounted matching up with the polarity of the local Bromsgrove transmitter, but though, according to your post code, located at an angle of 190 degrees, the Ridge Hill transmitter being at an angle of 217 degrees but which is a horizontally polarised transmitter.

You can of course study this for yourself by opening the undermentioned link, this giving details of the various stations and the Mux channels used said stations, as this will enable you to check where a channel is being received from.

It will also be noticed that the channels used by Bromsgrove are also used by two other stations, namely Larke Stoke and The Wrekin, this under certain atmospheric conditions being something which "might" cause problems with reception.

keith Blackham: The Digital UK Coverage Checker suggests otherwise. Ridge Hill is variable/poor whereas Bromsgrove is all good. This prediction should be used as a guide and not an exact representation of what you will find in practice.

I can't quite work out why Digital UK rates your chances of Ridge Hill so poorly. The terrain plot is here:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


At 32.4 miles you would appear to have clear line-of-sight, albeit with the question of a peak at 21 miles out which may be in the way and corresponds to somewhere around Storridge.

All that said, looking on Streetview, the vast majority of aerials are facing Bromsgrove, them being vertically polarised. And if you're tuned to UHF channel 26 for BBC One then you're tuned to Bromsgrove! If your aerial is horizontal and pointing slightly off-beam, which it must be, then this would explain the poor reception.

You need to do a manual scan for Ridge Hill channels: 28, 25, 21, 24, 27. Go to the manual tune screen and enter/select each channel in turn, but don't press the button to scan/add services. Instead, for each one, wait and see what the strength and quality is like and whether it's pretty stable.

jb38: Bromsgrove, The Wrekin and Lark Stone are SFNs, so might they not complement one another rather than interfere?

Dave Lindsay: Sorry for the delay in replying, this being due to working in another area which involved an overnight stay. However as far as your query is concerned, yes! in the majority of cases they do, and with no problems whatsoever being experienced with reception, that is provided none of the transmitters involved are only being received via diffraction and why I had mentioned "atmospheric conditions, as signals received under these conditions can suffer from elements of data corruption, which on its own is neither here nor there, but not if the signal is part of a synchronised SFN network.

My main thoughts being centred on The Wrekin, that is even although DUK indicates that reception from this transmitter is possible in B61, as I personally have my doubts about whether or not it can actually be received in Keith's B61 location, albeit with this being well-nigh impossible to confirm without a series of mobile checks being made.

I have a problem with channels on PSB3 and com7 Muxes. On my Samsung LE32C580. All channels on these muxes are subject to intermittent interference. All channels on any of the other muxes are O.K. with no interference.

When I look at the signal strength shown on the TV, the channels with problems show a signal strength of 90 but an error rate of 800 to 2000 depending on how bad the problem is. When the problem is not present, the error rate is between 400 and 600.

All other channels show a signal strength of 80 to 100 and an error rate of 0, even when the interference is occurring on the PSB3 and com7 muxes.

We are in Cheltenham GL52 area.

Is this a problem with the transmitter, or my reception system?

Tony: Purely on the information provided, it could conceivably be that the signal strengths are high to excessive, although this would be unlikely at such distance from the transmitter. HD signals tend to be affected before SDs with excessive signal. If you have an amplifier then turn it down.

Tony:

Thank you Dave. I don't have an amplifier myself, but as the signal is coming from a communal system, I assume that has some amplification of the signal. I will get hold of an attenuator and see if that resolves the problem.

Tony: Conceivably the amplifier could be being overloaded and all that installing an attenuator after will achieve is giving a smaller distorted signal. In such a case the amplifier needs turning down.

Then there's the point about everyone else in the block -- this doesn't help them, if you have indeed identified the problem.

The aerial system should provide suitable level signals from the wall socket in each dwelling. If it's not then the party responsible should be notified in order for it to be put right.

Also, if you don't have the two new HD multiplexes, COM7 and COM8, which give channels/channel/BBC4HD">BBC Four HD, BBC News HD and QVC+1HD, then this could be because the system is filtered to only allow through the channels (frequencies) of the designated transmitter, these being two new ones. Get the engineer to enable these channels, if need be.
