Tony: No, Crystal Palace's switchover (and therefore all its relays, of which Guildford is one) starts on Wednesday 4 April. Guildford stopping use of C41 is the pre-requisite for Hannington making full use of it. Nearly all switchover events happen on a Wednesday. Only SDN's restriction is lifted on the 4th, ArqA and ArqB will still be restricted until the 18th.
To remove the restriction, services need to be switched from the restricted antenna to the main antenna, which involves disconnecting and reconnecting. Guildford C41 is being released by multiplex 2, which is taking over the BBC low-power multiplex's channel for the two-week period between stage 1 and stage 2, so that has to move before Hannington's changes can start.
Digital UK only guarantee that the work will be done by 6am. There are no technical changes to the multiplexes' configuration, so you do NOT need to retune, unless you cannot get the channels at the moment.
It's likely that BBC Two analogue at Crystal Palace and relays will be shut down shortly after 12:20am if the schedule is similar to this week and next (the BBC like to shut down at a programme junction, rather than in the middle of a programme). BBC One may have already shut down as the programme junctions this week and next are at 12:05am.

Tony: According to Ofcom's latest document, on 18th April all three of Hannington's COMs (41,44,47) will go up to their full final power.
Digital UK Tradeview suggests that for Hannington there will be "COM power-up" on 4th and 18th April. However, the power is shown to increase to full level (25kW) for all three on 4th April and not increase on 18th.
I suspect that both of these sources are not entirely correct.
I suggest, as KMJ,Derby has said, that come 4th April, Guildford will relinquish use of channel 44 and therefore Hannington's (ArqA) will go up to full power.
Then two weeks later, when Guildford stops using C41 and C47, Hannington's other two COMs will go on full power.
Obviously, there will be no need for a full retune; just manually tune the multiplexes when they become available, except for poorly designed sets that don't have a manual tune option.

22nd March 2012 and I appear to have lost a massive chunk of channels - the BBC channels all vanished, however SKY news etc were OK. Retuned and now all the SKY has gone but I have BBC back and only 41 channels (previously 100+). (51.4816,-1.6213)
| link to this comment |
Mr Smith: You are in an area served by the Aldbourne relay transmitter. Now switchover has happened, this is only does not carry the full range of Freeview channels; it is a Public Service transmitter only. You received full Freeview before switchover, so you must have been getting it from Hannington.
The first thing to do is ensure that your receiver(s) doesn't choose to use the signals from Aldbourne. They use low channels and Hannington uses ones higher up, so as a matter of course, it is a good idea to have the aerial lead unplugged for the first 20% of the automatic tuning scan to avoid picking up Aldbourne.
The Commercial multiplexes will be on low power from Hannington for a few weeks more.
On 4th April, ArqA on C44 (carries Pick TV etc) will switch to its full final power. Two weeks later on 18th April, SDN on C41 (carries ITV3 etc) and ArqB on C47 (carries Yesterday etc) will go to full power.

In fleet we have received the new channels (hannington transmitter). However the signal is continually breaking up. Before today we did not receive any of the channels, so turning on of that mux at Hannington has worked but I hope that it is going to be turned up at some point.
The BBC mux is almost perfect, doesnt break up anywhere near as much

Mike Dimmick11:23 AM
Tony: This is all governed by trying not to interfere with the Guildford transmitter. The old digital aerials at Hannington only fire to the west, north and south (actually a little to the west of north and south), because most of the digital services were assigned the same channel as a Guildford analogue service and therefore would destroy Guildford analogue, for some viewers, if allowed to fire to the east.
All the COMs are broadcasting at a maximum 25 kW in some direction. Just not your direction.
Last night, as part of the first part of switchover, Guildford low-power Mux 1 was switched off. This allowed low-power Mux 2, previously on C44, to move to Mux 1's old channel C49, to clear C44 for Hannington's use. C44 at Hannington is ArqA - this transmission has now moved to the omnidirectional antenna at the top of the mast, so you should now be able to receive it.
The assignment of which service got which frequency did change a few times over the years - but it's definitely ArqA on C44, not SDN, which remains (with ArqB) on the restricted antenna until 18 April.

Hannington reception problems finally cured by Crystal Palace DSO:
Since Hannington DSO I have suffered from continuous multiple channel pixellation and audio interference. Following this morning's Crystal Palace DSO and a re-tune I can, at last, receive stable Freeview inc BBC South and ITV Meridian. I simply re-tuned without doing anything to the rig therefore the problems can only have been the result of Hannington service provision, which is is not really acceptable especially since location is only 097/12 from the Tx.
Thank goodness that nonsense is over. I hope other people's reception problems in the Hannington easterly sector are similarly resolved.

The MUX power increase on 4th April came through perfectly, eventually by the afternoon.
Despite what the Hannington Freeview list shows the MUX that changed on 4th April was ARQA on channel 44 NOT SDN on channel 41!
It had to be ch44 as that was the channel that was the first of the three to be freed-up from the Guildford transmitter (MUX2 ...going to ch49; this will then change to D3+4 and go to ch46 on 18th April)
Channels 41 and 47 are still awaiting their power increase on 18th April from Hannington.
This can all be seen on the GUILDFORD Freeview page.
Just to be clear:
Ch41 is used for MUXA (SDN)and will go to Ch48;
Ch47 is used for MUXC (ARQA) and will go to ch52; both on 18th April.

trevor: You are predicted as being able to have far in away better reception from Crystal Palace (especially from the 18th) over that of Hannington, as Hannington's main PSB transmitters although indicating good leave a little to be desired, and with the commercial muxes not indicated at as being able to provide signals above the status of poor at any time, this right into the future.
Adrian on the other hand and who has just replied to you, IS indicated as being in a position where Hannington is the best, and with Crystal Palace taking second place.
Obviously local conditions (obstructions etc) might well be applying in these areas and predictors don't necessarily take this type of situation into account, but that's the predictions seen for the code provided.
Just purely for a test, although Crystal Palace is about 40 degrees out from the rear of your aerial you should give CP's high powered (200kw) BBC1 a manual tune test to see the level indicated, it being on Ch23.
By the way on most equipment, if you go into the manual tuning screen as soon as you enter the channel number you intend to scan its level will immediately be indicated, this without actually having to scan it.

KMJ,Derby9:01 PM
trevor: Since 4th April 2012 analogue ITV1 from Crystal Palace is transmitted on C33 instead of BBC2. Digital Mux BBCA is transmitted on C23 instead of analogue ITV1. This means that your analogue TV now has ITV1 on button 2 and nothing on button 3.

Wondering if anyone can explain something. I have been looking at the levels for the different groups of channels. We are receiving PBS1 perfectly- my question is why are we not receiving PBS2 at all? According to the information at the top on levels PBS2 should be at 50,000 already - ie the same signal strength as PBS1.
Just to confuse things more we are picking up Coms 5 (not as well as PBS1 but alright) and that is only broadcasting on 10,000.
Why are we picking up channels broadcasting at 10,000 but failing to pick up some of the channels at 50,000. This may all be resolved on the final switch over date but just seems strange. Any explanation?
| link to this comment |
tim welby: I believe that the above is not entirely correct.
The Digital UK Tradeview predictor says that the positive offset is on PSB3 (i.e. C39+) and not PSB2. Furthermore, COM4 does not have a positive offset either. Briantist, you might like to look at this.
The Ofcom document, apparently updated January 2012, also says that Hannington's channels are not offset except PSB3:
http://stakeholders.ofcom….pdf
Also, COM5 is on its full DSO power of 25kW. COM4 and COM6 remain on low power until 18th April when the Guildford transmitter relinquishes use of these channels.
Tim, before I started, having simply looked at the channels at the top of this page, I was going to suggest that your problem may be that your receiver can't cope with the positive offset employed by PSB2, but I don't believe that this is the case.
I have been reading through your earlier postings that you made since switchover. You seem to have been having alot of issues since switchover.
As Mike Dimmick explained ( Freeview on Hannington TV transmitter | ukfree.tv - independent free digital TV advice ) the difference between pre-switchover signal strength and post-switchover strength in your direction is huge. You may have had an aerial installed that was sensitive enough to pick up the pre-DSO signals, but which is now drawing in too much signal and overloading your tuner.
The reason for the marked difference is due to the fact that pre-DSO signals were considerably weaker in the general direction of Guildford (the "Guildford notch") in which you reside. This was so as to protect those using Guildford transmitter against interference as the two shared channels. So you have gone from having low low low signals to high ones.
Have you tried fitting an attenuator?
| link to this comment |
T
tim welby8:29 PM
Thanks for your thoughts.
Pre first switch over date we didnt get any signal on any digital channel at all- so there has obviously been a huge improvement. However as you rightly point out, while some of our issues since switchover can probably be attributed to issues to do with Hannington, there are probably some problems within our system as well.
We are waiting till the completion of switch over before we worry about changing our system in any way. After this point we will look into an attenuator and other things.
I was looking up the positive offset (my background is pure mathematics not anything technical) is there something I should do to deal with that.
In my post it was really something that I found interesting that channels I got perfectly (the bbc multiplex) and PSB2 claimed to be the same power yet one comes through perfectly and the other not at all. I hadn't considered that the information at the top could be wrong- you may well be right. It was really a matter of interest rather than anything else.

Me too. I am also going to leave things alone until CP DSO is complete. We seem to be on a similar bearing from Hannington, which also seems to be co-linear with Guildford, and our symptoms seem to be similar to yours. I prematurely thought it was all over but last Monday Hannington dropped out completely (all six), and yesterday both Hannington and CP PSBs were pixellating, both with painful audio interference (not good mid-Grand National...)

Great to know that it is not our system (at least not only our system to blame).
We have found that the PBS1 multiplex (basically BBC) is fine at pretty much all the time. Looking at the levels, it is no wonder that some of the others are having problems being as they are at such a lot lower signal strength.
Thanks for posting, am hoping that means it will not cost to get this working right

tim:
Since DSO I am having a lot of reception problems here in RG27. I experience sudden pixellating and sudden loud audio interference on both Hannington and Crystal Palace. Prior to DSO we had no problems. After Hannington DSO I tried many things to find stable reception (other than changing the aerial...) to no avail so decided to leave it until after CP DSO. During yesterday (CP DSO) MUXs were dropping out but, using the OFCOM tables, I still couldn't find any pattern to the symptoms. Assuming CP DSO is now finally complete I may try again today. The barometric pressure was very low yesterday (976 HPa) but I am beginning to wonder if it is precipition-related rather than pressure-related. Should I really have to change both aerials to Wide-Band when reception was OK before DSO?

No, I don't believe so. If you have never had any digital channels at all then there would be a possibility that you needed a better Ariel. If you have ever received digital channels then as far as I am aware, it cant be the ariels fault the ariels fault.
I carried out a hard factory reset this morning, with the very satisfying result that my channels (only limited to PbS1 i.e. the BBC mux) have for the first timte arranged themselves into the correct digital tv channel numbering. Of course unfortunately I havent gained any that were meant to come through yesterday, but it is still a step in the right direction

Reception change June 2012
I am in Haslemere GU27 3RL and have a diplexed 2 aerial system pointing at Hannington and Crystal Palace. Our local transmitter is Freeview Lite and suffers from channel overlap with CP so isn't an option.
DUK trade view shows a reception change in May 2012 which will result in the loss of SDN, ARQA and B from Hannington. So far we haven't picked up these MUX's from CP (in line with DUK prediction). There is a further reception change shown in June 2012 which will degrade D3&4 for us.
Is there any information available about these changes?

Steve Flynn: I remember when you raised this issue a couple of months back:
Haslemere digital TV transmitter | ukfree.tv - independent free digital TV advice
I'm surprised that the Haslemere transmitter has been given channels that are used by another transmitter that will clearly interfere in its designated service area.
Whilst you could use Crystal Palace for PSBs only, it is London region whereas your nearest "designated" transmitter is Meridian.
The Digital UK Tradeview predictor just gives a guide to reception but does not give any indication of where this may be limited by interference and crucially, which transmitter providing the interferce.
In some cases it is clear; for example Crystal Palace which is "good" where you are is likely to be the culprit for degradation of Haslemere's signals.
I suggest that Heathfield might be the reason why DUK suggests that reception of Hannington's COMs and PSB2 will get worse in June.
See the "After Switchover" maps for C41, C42, C44 and C47:
UK TV Frequency map - channel C41 (634.0MHz) before switchover map | ukfree.tv - independent free digital TV advice
Heathfield would surely be the likely candidate as it uses these four channels but not C45 and C39 as used by Hannington's PSB1 and PSB3 which aren't forecasted to change in June.
What this doesn't mean is that you "will" have an issue. Hannington and Heathfield appear to be roughly 180 degrees apart for you.
If, for example, there are trees or a building in the direction of Heathfield, then this will probably work in your favour; helping to block Heathfield's signals.
Can you pick up Hannington's COMs now that they are on their full final power. Note that Hannington's PSBs are 50kW and its COMs are 25kW. The latter use a less robust mode which allows them to carry more services at the expense of some viewers in fringe areas.
| link to this comment |
Steve Flynn: I should also point out that as Heathfield is at 180 degrees to the direction your aerial is facing, the degree to which your aerial can "reject" signals from the back will probably play a part.
The pros that frequent this site can probably tell you more, but perhaps there are some types of aerial that have better rejection of signals from the rear than others.

Hannington is our nearest transmitter (we are in Maidenhead). Since the switch over began we have had a very unusual problem.
whenever we switch to a BBC TV or Radio station, it palys fine while the channel info bar is there, but when it disappears afer 5-10 seconds the channels automatically starts playing the BBC1 audio if we are on a radio channel and the BBC1 audio and video if we are on a BBC TV channel. All none BBC channels are fine.
If you then pull up any on-screen menu, it reverts back to the originally selected channel.
We are using a Sony freeview box.

B Brown:
Furthe to Dave Lindsay's response, go to your your TV's manual tuning option, and see if the TV is 'aware' of broadcast channel 39 (the channel Hannington uses for HD broadcasts).
If that channel is not available, then your TV does not have a Freeview HD tuner (otherwise known as 'DVB-T2').

Malcolm H: Confirming Dave Lindsay's comments.
I live on the eastern side of Crowthorne, right on the edge of the Hannington reception area. Using an XB16B aerial and all new cabling (both from the supplier mentioned by Dave Lindsay), I now receive all Freeview channels perfectly.
Reception of ArqA & ArqB muxes was pretty dire prior to 18th April (as was SDN prior to 4th April).
So a new/repositioned arial MAY help.

Malcolm H: Trees can cause issues with reception.
The signal being received may vary when the branches move, when leaves are on the tree or when they are wet. They may affect some channels and not others.
If it is BBC standard definition services that you are having difficulty with, then these are on C45. BBC Two analogue used to be on that channel, so did you suffer from intermittently poor reception on that channel?

Small problem this afternnon and evening - intermittent glitching on ITV1 Ch.3. Occurs at least once-per-minute, sometimesd 2-3 times in quick succession. All other channels fine. Hope this isn't going to be the norm.

Is switch over pretty much complete? I am living in fleet , and am restricted to PBS1 (just bbc channels).
I dont get any of the channels on Mux 2,3 which the info claims go out at the same power (50,000).
Briefly a couple of weeks ago I got coms 6- poor quality but it came through. This has now disappeared even though according to the information provided, it is being broadcast at 5 times more power now.
What are peoples thoughts? is this it? will coms 6 come back- I am baffled why it would appear for a while and then disappear again. According to more general predictions we should be able to get the whole range (I realize that these are often not reliable). Should we be looking into attunators or amplifiers or is there still some sort of improvement to come (and does anyone think that either of these things would make any difference anyway)
Any thoughts or explanations would be appreciated

DSO is complete for Hannington.
What broadcast channel are you receiving PSB1 on? It should be 45 for Hannington.
What signal strenght/quality does your TV or digibox show for broadcast channnels 41, 42, 44 and 47?

I have had a look and yes PSB1 (PBS1?) is coming through on channel 45 though only with a low percentage (in the few seconds I watched it was between 16 and 31) which means it is quite good these channels break down so little.
41,42,44,47 all come through as 0% (so not a suprise I cant see them), though 44 briefly flashed 18% before showing 0 (none of the others did this). Is this flash significant? It seams odd, surely either it can get signal or it cant.
What I dont understand is why PBS2,3 dont come through at all if they are at the same strength as Pbs1- though I do realize the explanation coould be extremely simple- the signal strength data is wrong.

tim: Sounds like the signal strength could be too high which is overwhelming your receiver:
Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice
Try connecting a set-top aerial. Or if the aerial plug is a screwed together one (i.e. not a moulded on type) then unscrew and remove the outer part of the plug and insert only the centre pin into the aerial socket. See if these improve matters.

Tim,
Prior to the start of DSO for Hannington in early Feburary, were you able to receive all multiplexes? PSB2 is broadcast on channel 42, at the same level as PSB1 on channel 45, so if you can receive PSB1, you should be able to get PSB2.

Adrian, prior to switchover no I didnt receive any digital mux at all. As to your comment about PBS2 that is exactly what I thought, hence the question. If the signal strengths are identical why does one come in perfect and the other not at all.
Dave, I will see if we have a set top ariel to try out, though I find this rather hard to believe it could be the case. Before switchover there was definitely no signal (all the internet signal checkers agreed). In the past we have been in areas which did have good signal and we never had the problem we are currently faceing

tim's: mapT's Freeview map terrainT's terrain plot wavesT's frequency data T's Freeview Detailed Coverage
tim: The likely reason that you were in an area with no signal is not because you have poor line of sight to the transmitter, but because the transmitter was not radiating an omnidirectionally. That is it was outputting a much weaker signal to its east side.
Now the signals are omnidirectional. So you have gone from being in a "very very low/non-existant" to "very high" signal area. This is quite an increase.

Adrian,
Yes I have done what you suggest. I carried that out earlier this week. That was quite nice as it has rearranged the channels into the correct order which before didnt happen.
Dave
You may well be correct. Would this show up on the power check feature on the recorder? I have gone through each of the channels that should be broadcasting other multiplexes. These are all reading absolute 0 (bar one which flickered for a fraction of a second on 18% before giving 0). If it were the case that the signal was now too high, should these readings (which are only to do with signal strength not what is on the signal) come out as zero?
tim
| link to this comment |
tim's: mapT's Freeview map terrainT's terrain plot wavesT's frequency data T's Freeview Detailed Coverage
tim: If the receiver is overloaded with signal, then the signal strength readings will be likely to be misleading.
That is because the circuitry is overwhelmed by the signal, it can't function normally.
The fact that there is an initial blip of 18% and then nothing could give rise to the theory that the signal level is too high.
Try putting less signal into the TV. For example, remove the aerial lead and hold the plug close (a centimetre or so away). The aim is to loose a bit of signal. Bear in mind that the receiver may take 10 or more seconds to adjust to your change, so wait.
Or as I said above, try removing the outer part of the plug (if it's a screw-together one).
When you do this, observe the signal strength meter and see if it increases.

Just a thought. With the system I have, the lead from the aerial into my freeview recorder. I then have a lead going from the out socket to my TV. It was my understanding that this means that my tv would get significantly weaker signal?
If this is the case it cant be that the signal is too strong, as on my tv I dont get any channels at all (including channels from PBS1).
Would this rule out the signal being to strong?

tim: Where a signal is split using an unpowered splitter (i.e. no amplification), then it stands to reason that the strength of the two outputs must be less than that of the one input.
However, where an aerial lead "loops through" a device, the signal is amplified to counteract the loss caused by splitting it.

yep, identical. Due to the fact that it finally allows us to record things when we are not here again, we have the cable going into the recorder rather than the tv (it then goes from the recorder to the tv as we have had it before but it seems signal is not strong enough for that)
I have no idea whether the tv would have recieved coms5 for the few days that it was available, as I did not try it during that period.

Now that the dust has settled for both Crystal Palace and Hannington...
I am in the fringe area known as Wokingham. I inherited an (inaccessible) aerial pointing at Crystal Palace but like to get BBC South local news if I can. I have successfully tuned my box so BBC South, from Hannington, is on logical channel 800. Probably 90 percent of the time this works fine - remarkably few drop-outs given that my aerial is pointing in completely the wrong direction. The other ten percent of the time (is it when it's raining, I'm not sure) it is unwatchable or cuts out completely with "no or bad signal" message.
How can it be so variable? Is it just teething troubles at the Hannington end? Is there anything I can do to improve matters?

Adrian,
In our area there was no digital signal till switchover, so everyone else pays for their tv. I have asked around but noone is set up to receive digital.
Interestingly, while they are not yet working the ITV channels and a few others have been bookmarked (channel holder but no signal yet) so I am thinking that perhaps the repeater in this area is just slow>

We have HD-capable Humax box & TV receiver and now that Meridian & Crystal Palaxce DSOs are done, want to switch our HD Freeview to Hannington, so we receive BBC South Freeview HD rather than Crystal Palace, as we've done up to now.
But Reading Aerial Services just told me that Freeview HD from Hannington is not yet available. I want to delay having them in until Hannington HD IS available. When will that be, please?

I mean I'm thinking that the relay (sorry wrong word) is taking its time on adding channels.
We went and bought a signal booster yesterday- so far no positive difference at all. We are hoping that when we have the right cable it will at least give us strong enough signal to have freeview on two devices

HD transmissions are available from Hannington.
However, BBC One HD is "regionless", so there is no Meridian version being broadcast, and although this may happen in the future, no date has been set. ITV HD does carry four regions, and from Hannington this is Meridian Southampton. If you look at the top of this page for the channels listed under PSB3 you will see the details of what is currently available.
Hope this helps,
Adam.

Hey, thanks, Adam, most useful.
I THINK that means that I should be able to get what I'm seeking: The BBC1 South regional news from Southampton ("South Today")- but I don't necessarily need this in HD (sorry, I didn't explain that fully) - but I DO want the other HD channels, coming from Hannington, that hitherto I've received from Crystal Palace.
If this provision is already in place from Hannington, I can approach the Aerial co. to ask them to come to do a test, to check we have the sufficient Hannington signal (about 2 miles due south of Reading town centre).
Thanks - if you could kindly confirm I've got the situation right, I'd be most grateful.
Best and regards,
