Interestingly, a TVonics MDR-250 box I have couldn't find the BBC A mux this morning. It reported "Signal quality: None" on ch 27.

I found an RF signal attenuator fixed the problem - too much power from Sandy Heath !
Dave Kimber
Wednesday 30 March 2011 11:56AM
I retuned my Sony VTX-D800U STB this morning. I now find that BBC2 keeps switching after a few seconds to provide BBC1 programme, even though the box says it is still on programme 2. Selecting BBC2 by any means gives me a few secs of BBC2 then BBC1 again. If I leave the EPG on the screen, then BBC2 stays in the background. Surely the 2k to 8k switch would not do this?
Dave Kimber
Wednesday 30 March 2011 1:26PM
Update on my previous post: I have done a STB reset and now it stays on BBC2 OK.
Mike Dimmick
Wednesday 30 March 2011 1:58PM Reading
Dave Kimber: there have been some reports of this on some Sony TVs up in Scotland. It may be a recurrence of a problem they had with Humax equipment a week or so ago. They seem to be using some new code for the 'Press Red' popup that appears during the news, or '(Red) SPORT' in sports programmes.

My hypothesis is that they've changed which MHEG program ID to run automatically when you select the channel, and the boxes still have a cached copy of a previous program with that ID that did something different (probably used for returning to the service you were watching when exiting from an interactive stream).

I excitedly retuned my TV this morning, and lo and behold BBC1/2/3 now have a nice strong reliable signal. Just one little thing - the data at the top of this page now lists BBC4 and the radio stations as being on both PSB1/C27 and MuxB/C67 (where they were before). And I definitely saw them coming up on C67 when tuning in. Is there another step here?
Briantist
Wednesday 30 March 2011 2:41PM
Bob: Yes, this is a common situation at switchover - too much signal is as bad for digital reception as too little.

Remember to remove amplifiers first, before fitting attenuation devices.

General note - if you are retuning you must do a "first time installation" or do this - www.ukfree.tv link icon My Freeview box has no EPG, is blank on FIVE, ITV3, ITV4, ITV2+1, has no sound or the channel line up is wrong | ukfree.tv - independent free digital TV advice . An "add channels" will only confuse your receiver.
Adam B
Wednesday 30 March 2011 3:13PM Dunstable
Brian, out of interest, why is MUX B not turned off at the first retune date, given that the new PSB1 mux carries everything that was on MUX B? MUX B is now just a subset of PSB1 that doesn't need to be there.

Cheers,
Adam.

I have a problem I'm hoping someone can help with.

My house has 5 TVs; kitchen, living room, bedrooms 1-3. The living room and bedrooms 1+3 receive all muxes fine, no problems at all. Signal strength is a little poor on 2 and A-D but I guess that is expected before the 13th. The other two rooms however, only receive 1 and B. Nothing at all in the 40s range.

I have tried various combinations of TVs and set top boxes in all the rooms, and the result is the same regardless of the equipment. The only difference in the rooms as far as I can make out is the length of RF cable between the aerial/booster-splitter and the wall sockets. The rooms are experiencing the problem have roughly double the length of RF.

Would the cable length be responsible for the problem? Do the cables wear over time? They were all put in approx 25 years ago when the house was built.

Any help would be appreciated, thanks.

Sterart,
No. The first 4 Freeview HD channels start on the 15th April at DSO stage 2. You will receive BBC1 HD, BBC HD, ITV1 HD & CH4 HD. I get Freeview SD and Freesat HD & SD so i'm looking forward to CH4 HD coming to Freesat in April. I would guess that the Freesat HD pictures will be slightly better than Freeview HD ones.
Stewart

Loft antenna in Newmarket (29m ASL) is working fine. Bought a 52 element wideband plus a £20 gigibox for the main TV a couple of weeks ago and it is adequate on all channels. Bedroom TV on old loft mounted Group A gives a slightly noisy signal on Analogue but the BBCA mux is good.

Am I right in thinking that someone who only uses Freeview from Sandy Heath won't have lost anything if they didn't retune yesterday? The new PSB1 has started, but the old MUX1 is still broadcasting, is this right?

Cannot get BBC1 or 2 after having retuned on main LoungeTV with outside aerial. Other TVs in house just on portable aerials work all except one in study on portable aerial. Main concern though is the Lounge modern upto date TV. what shall i do?
Mike Dimmick
Thursday 31 March 2011 1:53PM Reading
Bain: Insulation does perish as the plasticizer chemical evaporates over time. If walls are damp that can allow water to get in, which changes the cable's behaviour. Generally you see some loss at low frequencies and higher losses as the frequency increases.

External cables are subject to wind, rain and UV light, which will usually make them wear out sooner.

For digital TV it's recommended that you use 'satellite grade' cable, which has a screen of dense braid over metal foil tape. The cable usually used for analogue TV tended to have a bare minimum of screening braid, which to be honest wasn't really sufficient to keep out electrical noise. Electrical noise on an analogue picture caused occasional bright lines. On a digital signal it causes errors, which - if there are enough of them - cause picture breakup and, rapidly, complete drop-out.

The longer the cable is, the more signal will be lost. Again, 'satellite grade' cable is intended to deal with very low signal levels and loses a lot less signal than so-called 'low-loss' coax.
Mike Dimmick
Thursday 31 March 2011 1:55PM Reading
Mrs L Hardy: Can you provide a full postcode please?

If everything worked before switchover, there's a chance that signals are now too strong rather than too weak. If you have any amplifiers, try removing them, or turning down if it's adjustable. If that doesn't help, or there aren't any, try adding an attenuator.

hi
Have been receiving digital signals on BBC - ITV etc for the last 5 years - but have lost all BBC stations yesterday - I have a Samsung Digital Terrestrial receiver S1R-U200iinto an analogue Sony TV - I have retuned the receiver several times -no luck - is it a case of having a new TV or freeview box - thank you regards Robbie
Bain
Thursday 31 March 2011 3:29PM Bedford
Mike: Thanks for the response. I would imagine that all the cables are coax rather than satellite grade, so that would probably explain the problem.

The issue now then I guess it the fact that all the cables are built into the walls and the loft floor, so replacing them is going to be a pretty big job.

Robert Robinson: I'm afraid this box is on the list of 2K-only equipment at www.digitaluk.co.uk link icon http://www.digitaluk.co.uk/2kequipment . It can't be fixed with a software upgrade. You'll need to get a new Freeview box.

The new multiplexes use an 8K mode which is more robust when reflections are picked up. It's also the mode that most other countries are using. We're fairly unique in ever having used 2K mode. New boxes should all support 2K and 8K modes. (RG47SH)

Thursday 31 March 2011 11:38PM
Until yesterday, I was able to receive all freeview channels I know of. Like Mrs L Hardy, yesterday I stopped being able to receive BBC1,2,3, but continued being able to receive channels on other multiplexes. I can currently receive a total of 90 channels, but no BBC1,2,3. I have a signal booster, but turning this off causes many other channels (eg, ITV1,2,3) to become unavailable, and doesn't bring BBC1,2,3 back (including after a rescan); without the booster on, I can still receive BBC 4, Film 4, Dave, etc (56 channels in total).

I'll try getting hold of an attenuator; hopefully the problem is that BBC1,2,3 are now too powerful, but the other channels which haven't been boosted yet are still too weak. Hopefully after the other channels are boosted, I'll just need an attenuator, and no longer need the booster.

I've recently been given a digi-box (Goodmans GDR-10)which I thought would be handy for the upstairs TVs following the switchover. Existing set-up is: Skydish for the main lounge TV,2 x professionally-installed roof aerials aligned to Sandy Heath and Sutton Coldfield also serving the main TV, and a D-I-Y loft aerial aligned to Sandy Heath serving the upstairs TV. Original plan was to re-route the roof aerials post-switchover to the bedroom TV(s).
Tried the digi-box yesterday & got good reception on Ch 27 and patchy on one or two other channels using the roof aerials,also good on Ch 27 (but nothing else) from the loft aerial. Having spent a couple of hours on this very helpful site I've decided my best bet is probably to wait until after 13th April and then see how things look before spending any time/money on aerial re-routes / upgrade? Secondly, although I seem to be equi-distant from 4 transmitters the aerials I have do seem to be aligned on the best two ie Sandy Heath and Sutton Coldfield but will there be any "interference" problem during the period April to September when one has switched over to digital & the other hasn't? Or will the stronger digital signal simply "swamp" the analogue one?
Any comments will be gratefully received.
Mike Dimmick
Friday 1 April 2011 3:56PM Reading
Trevor: I don't imagine *everyone* did. Multiplex D has not yet switched over, but it's possible that some interim change was made in preparation for the next change.

On the 13th, Mux D changes mode becoming ArqB and moves to C67, currently used by Mux B - generally the numbers got the best allocations, then A, B, C and D in that order. That may improve matters. However, some people may lose them due to the change in mode, which gives more capacity but requires more signal compared to the level of interference.

The final re-configuration for this multiplex is planned to be on 14 September.

Ofcom's latest stations table, incorporated into the licence by reference, says 'Until further notice, may use transitional antenna'. This is against the final configuration, so could relate to the situation after DSO. The notes for Multiplex 2 (D3+4) and B (HD) both say 'Use transitional S1 antenna until 27 June 2012', though this is probably to avoid clashing with another main transmitter that won't switch over until later - possibly Rowridge.
Mike Dimmick
Friday 1 April 2011 3:58PM Reading
Rob: So far, only the main BBC multiplex has switched over. The rest of the multiplexes switch over on Wednesday 13 April.
Mike Dimmick
Friday 1 April 2011 4:11PM Reading
David Howard: While the public service multiplexes complete switch over on the 13th of April, the commercial multiplexes don't complete until later in the year. Once they do, there will not be a clash. They have to move to get out of the way of Sutton Coldfield's switchover, in fact.

Multiplex A from Sandy Heath uses the same channel as ITV1 (analogue) from Sutton Coldfield, C43. Mux C (ArqA) uses the same channel as BBC Two from Sutton Coldfield, C40. It's likely that this will cause a noisy analogue picture on the TVs connected to the Sutton Coldfield aerial, and nothing much usable on these muxes on the TVs connected to the Sandy Heath aerial.

When Sutton Coldfield switches, C40 becomes the HD multiplex and C43 becomes BBC A. Sandy Heath ArqA therefore moves to C31 a week before BBC A starts at Sutton Coldfield, and ArqA moves to C67 (freed by ArqB moving to C48) a week before the remaining changes at SC.

If the two aerials are linked together with a diplexer, to put the signals on one cable, you may find that it only includes Group A channels (21-35) from Sandy Heath, and only Group B and above channels (37-68) from Sutton Coldfield. This means you won't get the commercial muxes from Sandy Heath when everything's complete (you might get ArqA when it's on C31). However, they have the same content at all English transmitters anyway.

I hope that's, um, clear?
David Howard
Friday 1 April 2011 6:53PM Northampton
Mike Dimmick: Many thanks for your help. I didn't expect it would be straightforward - looking out across the rooftops from my study/bedroom window I see aerials pointing East, West and South ! My two roof aerials are indeed linked together (there's a brown plastic box which is presumably the diplexer, happily located in the loft)so it seems that once the switchovers are completed in the autumn I'll be receiving all available channels from one transmitter or the other, and which is which will only be an issue as regards regional news programmes and the like. If necessary when the time comes I can no doubt "unlink" the two leads from the roof aerials to check what I'm getting from each in terms of channels, signal quality and strength etc. Assuming they are OK individually would it be feasible to incorporate a switching facility ie along the lines of the audio source selector I use in my hi-fi set up,in order to choose aerial A or B or, perhaps, A+B or would this cause problems eg with the box re-tuning itself every time? At any rate it seems there'll be little if any advantage in leaving the aerials linked once the switchover is completed so if necessary I'll just make a choice between them - I guess I must be in a better position than many people and shouldn't complain about having too much choice !

My 3 year old Philips digital TV cannot access BBC digital text anymore since Phase 1 of the switchover.
I am told by Philips this should be working by Phase 2 but I am not convinced.
Others must be having similar problems surely?
Mike Dimmick
Saturday 2 April 2011 10:55AM
Dave: your TV may be confused by the data appearing on both the high-power BBC A multiplex and on the low-power Multiplex B. However, my understanding was that they were carrying it on both Mux 1 and B before switchover. There are stories that the BBC will soon be removing it from Mux B in the rest of the country.

Did you do a factory reset or first time installation, not just an automatic scan? Sometimes receivers remember information from previous scans which conflict with the new information. For instructions on how to do this for your TV, see www.tvretune.co.uk link icon TV Re-tune ____The digital text data will not be present on the HD multiplex, which replaces Multiplex B at phase 2. So it should sort itself out then.

Otherwise, it's possible that there is some incompatibility with the current digital text data and your TV. Check that the TV has the latest firmware available at www.philips.co.uk link icon 
Philips - Contact and Support
 . Generally they should automatically update when a new version of firmware is broadcast, but this usually requires that the set is left on in standby overnight, so viewers who unplug their sets overnight don't get the updates. (RG47SH)

Saturday 2 April 2011 4:20PM
Jim: Go to Find out how to receive Freeview and Freeview HD | ukfree.tv - independent free digital TV advice and click 'By Direction'. That shows the bearing as 102°, slightly south of east.

A compass will not quite show the right bearing because these bearings are east of true north, while the compass needle points to magnetic north, a few degrees different. However, the aerial has a relatively wide cone of acceptance so it doesn't have to be that accurate - just adjust the aerial for best results. (RG47SH)

Bob
Sunday 3 April 2011 7:55AM
There seems to be a problem with Sandy heath, caused I suspect, by a duplication of channels on MUX ch 27 & 67.
It seems OK to start with, but a few hours later, BBC1 etc VANISH!
The cure seems to pull the aerial plug out, so the re-scan misses ch67 - if your box does not tell you which channel it is scanning, there will be a percentage bar, over 75% will be the point to "pull out"
This may not be a problem with some boxes, but it certainly was with an old PVR Goodmans GHDD1782

I've also had problems with a Sony VTX-D800U freeview box as reported by Dave Kimber, where (after retuning) BBC2 keeps switching to BBC1 after a few seconds.

Following Dave's advice, the problem went away after a mains power cycle.

Menna: check for a loose, disconnected or broken cable, because you should be getting perfect reception. Also, if you retuned before 6am on Wednesday, retune again - all services were off-air at that time.

If you didn't retune at all on Wednesday, you would have lost BBC channels but should still have all the others.

Some boxes auto-retune every night and could have been confused when the services were off air.
Mike Dimmick
Sunday 3 April 2011 8:59PM Reading
David Brient: if there's a time of day that you've noticed that ITV, C4 and C5 were normally working, try retuning it then. Or try a manual update of channels on C45.

You are predicted to have variable reception of these channels at the moment. No problems are shown once switchover completes on the 13th (10 days time).

Thanks very much to Dave Kimber - I was having similar problems with the Sony DTX-V800U box. BBC2 would switch to black a few seconds after closing the EPG (but fine all the time the EPG was visible) - even after a full re-tune.

Power cycling the box completely seems to have cleared the problem!

I am in the Cambridgeshire and feed off the Sandy Heath transmitter. When I did a rescan on the 30th. I was left with three selections as follows:

Cambridge and Beds. 18 services
Cambridge and Beds. 21 services
Midlands. 18 services

I know that I can ignore the Midlands(Waltham) but which of the other two should I select, I can only select one.

John: When the broadcasters make changes to the transmitters, they often add a dot to the end of the region name, so they know that a change has gone through. You probably have one with a dot and one without. I believe the boxes are supposed to ignore this, but not all do.

It also ought to be possible to select top preference and second preference, in case you actually want services from two regions, but again, not all boxes allow this.

What make and model of box do you have? It's worth checking to see if there's been an update that you've missed - particularly if this is a new box but could have been sitting in the shop or warehouse for a while.

The 21 services region is likely to be the BBC A multiplex, while 18 services is likely to be the low power Multiplex B - all services on Mux B are also on BBC A for the next 10 days, except for Sky Sports 1 and 2. On the 13th, Multiplex B closes for good (at Sandy Heath) and is replaced by the HD multiplex.

It may simply be that the box is telling you it's found three different versions of BBC Four, CBeebies, Red Button and the BBC radio stations.

My understanding is that it should also have listed the ITV channels if your signal quality is good enough to receive those. The prediction looks reasonably good - have you had Freeview before? Are you using an outdoor, roof-mounted aerial, or a loft aerial?



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.
