Our transmitter (Bluebell Hill) is due to switch in June. After the switch I am wondering whether I will need an attenuator as Digital TV requires 40-60dbuv. Realistically, have many people required attenuators in previous transmitter switchovers? If so, I will get a few ready for it! Postcode ME73QP.
Mike Dimmick
Thursday 31 May 2012 3:08PM
Mark Barden: My belief is that the CAI-recommended levels for digital TV were set mainly to ensure that the analogue signals didn't drive amplifiers into non-linear regions, causing intermodulation. It wasn't because 60 dBuV on digital alone would cause intermod. If your signals are currently in spec, an additional 10 dB on each is unlikely to be a problem.

You are only 5 km away from Bluebell Hill and appear to have clear line-of-sight. Plugging those figures into www.megalithia.com link icon Field Strength Calculator suggests that even with no aerial gain and 10m of downlead it could be over 80 dBuV on C39 (ArqA mux). I'd say that you might need attenuation - it'll depend on how much the signal is attenuated by neighbouring buildings and trees.

When my old style TV went bang last Friday we splashed out on a new Samsung UE32ES5500 LED HD 1080p Smart TV, 32 Inch with Freeview HD. As we're on Bluebell Hill we wont experience HD until the 27th, but I would like some info about HD. According to the TV salesman in John Lewis, freeview HD is only 720p as aposed to 1080. He was quite adamant about this so I did a Google when I got home but the info is inconclusive. Can I hear the opinions of our resident experts here please.
Thanks

Would like to know if anyone else had problems with reception of BBC programmes on Tuesday when watching the Jubilee celebrations. The picture kept breaking up on my set and eventually disappeared altogether. NO SIGNAL came up on the screen on all BBC programmes. ITV seemed o.k. although lost the sound at some stage. I re-tuned the set 3 times and in the end BBC returned but it took a while and spoiled he day. Digital help no. I tried had nobody answering so no joy there. Anyone have any answers?

Dave Lindsay
Friday 8 June 2012 10:41AM
Colin Wardley: As previously advised ( Are you really watching free TV in high definition? | ukfree.tv - independent free digital TV advice ) Bluebell Hill does not broadcast HD until 27th June.

Therefore if you received it previously you must have been picking it up from another transmitter. Because this was likely to be off-beam for your aerial, reception was always expected not to be perfect. Therefore it may be hit and miss.

Bluebell Hill transmits 20KW, Crystal Palace transmits 200KW. Before switchover my BBC channels on Freeview were 100% signal Strength and Quality. Now BBC channels are 20% signal strength and 40% quality. I am 4 miles from Bluebell Hill and told to pay for my aerial to be repositioned to Crystal Palace 20+ miles away. We already pay an outrageous licence fee and are now expected to pay more because of BBC incompetence.
Adrian Bance
Wednesday 13 June 2012 11:19PM Gillingham
This page declares that "this transmitter has no current problems" yet when I telephoned BBC technical staff to complain about deterioration of signal strength and quality I was told that "Bluebell Hill is experiencing a number of problems"
Given how much we pay for the licence fee this situation is unacceptable and we deserve a refund!
Dave Lindsay
Wednesday 13 June 2012 11:44PM
Adrian Bance: On the basis that you had 100% strength before switchover (which may suggest that it was bordering on the excessive then), I suggest that the problem is that the signal being fed into your tuner is now too high and is overwhelming it. High signal level has the same appearance of low and poor signal, that being that the signal strength deteriates and quality goes due to the distortion.

Payment of the Fee does not guarantee availability of signal or reception of signal. The reason for this increase is so that other Licence Fee payers can now receive the signals.

For an explanation of too much signal, see www.ukfree.tv link icon ukfree.tv - independent free digital TV advice

If you have a booster (and it isn't installed for the purpose of splitting the signal to feed separate rooms), then it does beg the question why when the signal beforehand was so strong. This should be removed.

If you don't have a booster, or if you've removed it and the problem persists, then fit an attenuator (probably a 20dB variable one) inline with the aerial lead to reduce the signal level.


This is an independent website, as it clearly states. The the information provided on it is obtained from official sources and simply reflects what those sources say. If they are wrong then it cannot be right.

I have just checked the BBC Reception site www.bbc.co.uk/reception and it reports no problems with Bluebell Hill TV. The BBC only reports on its own services.

The other source that this site uses is Digital UK and you can view the source information at www.digitaluk.co.uk/engineeringworks

Or underneath the text at the top of this page that says that there are no faults, click on "Click to recheck" and it will recheck those sources. Clearly as this site sources its information from third parties and those third parties don't notify the site when fault statuses change, then it is only going to change on here when it checks the sources again.

Hi - since the retune yesterday we are experiencing weak signal strength and quality problems on certain channels - we had no previous problems!

Channel- strength - quality
24 84% 100%
39 83% 100%
42 30% 83% very poor
45 40% 95% occasional break up
46 48% 100% usually ok

I would have thought all channels would be of similar strength and quality as they are all coming from the same transmitter (Bluebell Hill) - Any ideas what the problem could be?
Dave Lindsay
Thursday 14 June 2012 1:33PM
John Langley: C46 is now on full post-switchover power and the rest remain on their pre-switchover "low" power.

Based on the readings you have given, I am wondering if you live in a strong signal area, or at least your aerial is providing a very strong to excessive signal, the latter being a possibility for C46 now and for the rest when they go up on 27th. Without knowing your location, it isn't possible to get an idea of how likely that might be the problem.

What stands out to me is that for the high-power multiplex on C46 you only have a strength of 46, yet 24 and 39, which are still on low power, are in the 80s. With the low-power signals you have ample strength so I suspect that the low strength reading for C46 is because it is excessive and requires reducing.

42 and 45 are close to 46, so perhaps latter the high power signal is acting to desensitise your receiver when it is tuned to the formers.

This can be likened to walking down the street at night. When car headlights come towards you, your eyes become desensitised making it more difficult to see the relatively dark surroundings.

If you have a booster (and it is not used to split the signal to different rooms) remove it. Once you've done that, if the problem prevails, you may need attenuation to bring the level down even more.

You may find that as you reduce it, not only will the strength of C46 go up, but the quality of 42 and 45 will improve.

Thanks Dave Lindsay - must say it all sounds v logical now you have explained it. We have a high gain digital aerial (used to be on my daughter's house in poor reception area until she moved). We do have a multipoint booster to distribute to a number of rooms into which the aerial connects.

So I assume you can buy attenuators from the likes of Maplins - any suggestions as to the likely value I should purchase or can you get variable ones?
Dave Lindsay
Thursday 14 June 2012 5:35PM
John Langley: Due to the fact that the pre-switchover digital signals were weaker, some aerials have been replaced with higher gain ones. Plus the fact that with some transmitters, including Bluebell Hill, some pre-switchover digital channels were out of the native analogue group.

Bluebell Hill was Group E for four-channel analogue which covers the top two thirds of the band. All but two of the pre-switchover digital channels are in Group E, but two are below it (in the bottom third, aka Group A).

Sensitivities drop off gradually, but the fact that the weaker signals are out of group would have been likely to cause issues for some futher away. Wideband aerials may have been fitted so as to pick up the two Group A channels.

Oh, and there is no such thing as a "digital aerial" ! I presume you have a wideband aerial.

After 27th, all Bluebell's channels will be within Group E, with only one being outside of Group B (middle third) and at that it is only one channel outside, so Group Bs will probably work.

For an explanation of aerial groups, see www.aerialsandtv.com link icon Aerials, TV Aerial and Digital Aerial

-----

I digress.

What you don't know is if the overloading is occuring on the input of the distribution amplifier or the input to each TV or a bit of both.

If the signal on the input of the amp is too high for it to cope with, then it stands to reason that the outputs will be distorted. No amount of attenuation of the outputs will right the problem and no amount of reduction of amplification will right the problem.

So you need to go to square one and see what sort of level you have from the aerial by connecting directly to it.

You "may" find that there is that much signal that you replace the powered amp with a non-powered splitter.

If you still have your old aerial (the one that you replaced the current high gain one with), then that may be suitable. All channels are in group and the signal strength will be on a par with the former analogue that it used to pick up.

For more information on this subject, see www.aerialsandtv.com
Dave Lindsay
Thursday 14 June 2012 5:47PM
John Langley: You can pick attenuators up of sites like eBay. ATV also sell them.

I personally find that, since Maplin went onto the high street, its prices tend to be high and that the stuff it sells can be obtained for less from online sources.


It's good practice to use F-connectors for connections that are perminant (so to speak) such as in the loft. Use coax connectors for behind the TV set.

Some attenuators have coax connections, some have F-connectors.


To connect a TV directly to the aerial, connect the cable from it to one of the output feeds to one of the rooms. Bear in mind that there will be a certain amount of loss in that cable; that is the signal coming out of the cable into the TV will be lower than that coming out of the aerial cable (in the loft) and going into the feed to the room where the TV is.

You could take a TV into the loft and try it directly.

And/or reduce the level of amplification if it has a control on it. See if this rectifies the problem.

KMJ,Derby
Wednesday 27 June 2012 10:41PM
tony: It is possible that some parts in the South of England are currently experiencing the inversion effect at work, resulting in normal reception being blocked by out of area signals. Apart from that, the Digital Uk postcode checker shows that predicted reception for the COM muxes at your location is best from Crystal Palace. In fact you are shown as possibly losing ArqB completely from Bluebell Hill in due course! You could try to do a manual tune on C45 to see if there is a usable signal for SDN (QVC etc) from Bluebell Hill, after first clearing the channel list of any existing data for the SDN channels.

Thursday 28 June 2012 9:55AM
Well this is good. After the switchover on the majority of my freeview sets I no longer get Bluebell Hill even though I live about 5 miles from the transmitter. All I can get is London and East Anglia, not a lot of good. On a manual tune, how do I 'target' Bluebell Hill and exclude the others???
Dave Lindsay
Thursday 28 June 2012 12:34PM
Tony Adams: During the automatic tuning scan, it looks at UHF channels (equivalent to frequencies) from 21 to 69.

Crystal Palace (London) uses channels in the 20s and number 30. Bluebell Hill uses channels ranging from 39 to 54.

You can therefore avoid Crystal Palace by unplugging the aerial for the first 30% of the scan. However, if the Anglia transmitters you are picking up are Rouncefall and Sudbury (these operate using the same frequencies), then you can't avoid them without missing out some of Bluebell Hill's.

Rouncefall/Sudbury uses 44, 41 and 47 for BBC, ITV1 and HD respectively.

If you can wipe the channel memory altogether and manually tune, then do that.

For Bluebell Hill you need to tune to:

46, 43, 40 (HD), 45, 39, 54

If you can't wipe the memory, perhaps by starting the automatic tuning scan with the aerial unplugged and maybe stopping it just after it has started, the objective being to "blank" what's stored. Or maybe run the automatic tuning scan through fully with the aerial unplugged.

If you have it all tuned in but wrong (e.g. you have BBC London), then it may well have put Bluebell Hill in the 800s. Therefore, when you manually tune to Bluebell, it may do nothing because as far as it is concerned, it has tuned to Bluebell.

Failing that, run the scan with the aerial unplugged up to 55%. This should pick up C54 from Bluebell which is COM6 (Yesterday etc) ONLY.

Refer here for services by multiplex (those with a bullet in the "E"/England column apply):

www.dmol.co.uk link icon DMOL Post-DSO Multiplex Channel Allocations

If at this point you only have those in COM6, then manually tune the other four (or five if you have a HD receiver).

The numbers I gave above are in order of multiplex.
Roland Rippingale
Friday 29 June 2012 7:40AM
Bibby: I have manually retuned to all channels on Bluebell Hill and installed them successfully. However, cannot get channel 40 (HD). We have 3 HD ready TVs in our house and none of them can receieve channel 40. When I try to manually tune channel 40 just get the message no channels available.
Dave Lindsay
Friday 29 June 2012 10:50AM
Bibby: Try again tuning the HD services. I have read reports on here of people with the same issue and someone even suggested that once switchover happened in the South East, HD wasn't being broadcast. Someone has posted this morning to say that they have retuned today and are now picking up HD from Tunbridge Wells transmitter.
Dave Lindsay
Friday 29 June 2012 10:52AM
Roland Rippingale: HD Ready means that the TV can show HD pictures but does not have the means to receive HD signals. Follow the link by clicking the words "HD Ready".

In order to show HD pictures broadcast after switchover, each TV will require a separate receiver (box).

Dave Lindsay
Sunday 15 July 2012 12:51PM
carl: This is a sure annoyance of the design of some receivers that retune as they see fit. See if there is an option to disable this "function". If not, then maybe you can attenuate all signals (which will bring down all their levels) in the hope that Storeton Granada will continue to be the highest and therefore chosen.

If you are receiving Yorkshire, then you must surely be getting it from Emley Moor which is horizontally polarised. Storeton Granada is vertically polarised, so it must be a strong signal if it keeps defaulting to it when it has opposite polarisation.

If the above doesn't resolve the issue, then Storeton Granada uses only Group A channels, so you could fit a Group A band pass filter which will only allow Group A channels.

Emley Moor is all Group B.

Briantist: Yes, I do realise that clicking on what you have mentioned gives a somewhat different indication, but I feel that what Steve Williams is possibly referring to is when his p/code is entered into the site settings box the result of this action has Bluebell Hill at the top of the three stations mentioned, rather than it being second from the top, the natural assumption being that the one listed at the top is the prime station.

As far as DUK's forecast is concerned, there is a horizontally running band of extremely poor reception that runs right through Colchester from just under Braiswick on its top side to just under Castle Park on the bottom, and I assume that's what DUK's predictions are based on when made with reference to the code given.

This strip can be seen on the map at the top of this page if Colchester is zoomed in on.

Briantist: And of course I forgot to clear the site settings box, hence I am in Colchester!

jb38: Sorry, I should have said that the link I provided was to the map of the postcode that Steve Williams provided, as per the "map" link next to his post.

Briantist: No problem whatsoever! as I fully understand that it wasn't the coverage from a single station that was being illustrated.

By the way many thanks for sorting out the sites Twitter link access problem, as with the listings shown not being section dependant but in a continuous stream I find this extremely convenient for making a quick check now and again to see if anyone has replied to any request for further info that I may have made.

D: In "some" devices you can delete the offending channels whilst in the EPG listings guide menu, sometimes called "edit channels".

Hi we have an old portable with a set top digital box and haven't been able to get bbc since the switch over. I have tried on numerous occasions to retune, both automatically and manually, but it still says we have a poor signal so no bbc. We have a digital tv downstairs that works brilliantly. So my question is do I need to

1. Get a new digibox
2. Get a digital tv
3. Get a new ariel
Or 4. Reposition my ariel

Sorry I am completely rubbish with this sort of thing!

Julie ayling: Have you tried the set top box downstairs to see if it will receive the BBC channels on an aerial connection that you know to be working? If it works, you know that there is a problem with the signal being supplied upstairs and you will need to reposition or improve the aerial. If it still refuses to receive the BBC mux there could be a problem with the sensitivity or characteristics of the box, in this event if you give details of the make/model of the box a check can be made as to whether it is one known to have issues. Likewise, if you give some indication of your location, preferably a postcode, a check can be made on predicted reception in the locality.

Yesterday I suddenly lost signal from ITV3, Yesterday & Film4
I tried a retune but still could not get a signal.Do you think this is a reception problem or a receiver fault.
I have a new Sony KDL40HX853

Jonathan Currah: It appears that you lost reception of SDN and ArqB muxes. Check that your receiver is tuned to the correct transmitter for the direction in which your aerial points. For Bluebell Hill this is C45 for ITV3 and C54 for Yesterday/Film4. You are predicted to have good reception possible from several transmitters, so incorrect frequency selection during a channel scan is possible. There is also the possibility that tropospheric ducting caused out of area signals to block reception of the missing channels, this being possible whichever transmitter is tuned in, but even more likely if, by chance, these two muxes were tuned to the "wrong" transmitter.

Thanks for your help. I have got a signal now but no info on EPG on some channels ( including those mention above ) unless I tune to those channels. I think my TV has tuned to more than one transmitter and I don't seem to be able to delete unwanted ones.
Any suggestions?



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.
