I live on Thorpe Park, in Norwich and prior to the switch over had all freeview channels. Now it seems I cannot recieve things on COM4 and COM5.
I have a wharfedale DV832BN freeview box and our aerials (on the flats) were all re-done last year (so people could have the option of sky).
I have spent ages scanning these helpsites etc and can't seem to find an answer that I can make sense of! I have also re-set, re-scanned etc several times.
Does anyone know (and willing to explain to a non technical type) what this may be down to- is my freeview box likely to be outdated, or is it more likely an aerial thing?
All help greatfully recieved.

Blackcat: I am thinking that it might be an issue with the aerial system; not a fault, but due to different frequencies being used that weren't used before.
Is this a block of flats with a single aerial or do you have an aerial each? The latter is unlikely.
The multiplexes (groups of programme channels), e.g. COM4 and COM5 each have their own frequency. With TV, we usually refer to the frequencies as (UHF) channels 21 to 69 (not to be confused with logical channel numbers on a TV, 1=BBC1, 2=BBC2 etc).
Analysis of what Tacolneston used before switchover and what it uses now shows that COM4 and COM5 are on two channels that are a bit lower down than those used before switchover.
Pre-switchover, the five UHF channels used for analogue were 62, 55, 59, 65, 52 and the six digital ones were 63, 60, 53, 58, 61, 64.
Post-switchover, the six digital channels are (in order) 55, 59, 62, 42, 45, 50.
COM4 and COM5 are on Ch42 and Ch45 respectively, which is lower than those used before switchover. I suggest that this could be an explanation for the cause of your problem.
Your aerial system might have been set-up to allow the frequencies used previously through (from the aerial to your aerial socket).
If it is the aerial system that is not supplying the COM4 and COM5 signals to tennants, then only adjustment of the system will fix the problem and that is the responsibility of the landlord rather than the tennant.
Whether the above hypothesis is the reason for the problem is probably largely irrelevant as far as tennants are concerned. The responsibility probably lies with the landlord.
You could ask your neighbours if they have the same issue.
I also suggest that you try manually tuning in these two multiplexes (if your box allows manual tuning).

Reception in this area ip173at is no better than it was before switchover.Without a booster
there would be no receivable signal.At times
watching freeview is a complete waste of time.
Is it likely to get any better,if not the only
alternative for us is Freesat.

E.HOLMES: Which channels does it affect?
Have you confirmed that your receiver is tuned to Ch55 for BBC and Ch59 for ITV1/C4 and not 28 and 23 which is Aldeburgh or perhaps 44 and 41 which is Sudbury?
This information will likely be given on the signal strength/quality screen and applies to the programme channel being viewed.

Hi,
I live in Norwich and have digital set-top box connected to an analogue tv and I believe the tv aerial is digital compatable with the Tacolneston transmitter. Since the digital switch over in November 2011, I have noticed a problem with some of the Freeview channels in that if I switch off the set-top box, it looses the following channels in the Mux category PSB2 D3+4:
3) ITV1
4) Channel Four
5) Channel Five
6) ITV2
13) Channel 4+1
14) More 4
28) E4
By undertaking a first time installation scan each time I switch on the set-top box I can retrieve these channels but this is obviously not an ideal situation.
As suggested by your advice page I have also followed the recommendations and removed the tv aerial from the set-top box, undertaken a scan of the channels to wipe the memory followed by another scan after I have plugged the aerial back in. This also provided access to the aforementioned channels but they were lost again as soon as I switched off the set-top box.
Just wondering if you can advise if this is a temporary problem and whether you have any other recommendations?
On a slightly different note, just before the digital switch over in November 2011 a problem with my other tv became apparent. It lost the ability to produce a picture but still had sound, I tried plugging in a digital set-top box and a dvd player but on each occasion there was no picture just sound. On its own the tv is not digital compatible so it doesnt provide any programme sound now, although when switched on it does provide the fuzzy noise but no picture. On the basis that I think the tv is at least 10 years old, do you think I should take it to my nearest recycling facility?
Many Thanks
Adele

Adele Dodgson: A receiver "forgetting" stored channels when it is switched off is usually a sign of it not having enough memory. If you post the make and model number we may be able to seek out its specifications.
The interesting thing here is that these are not only all on one mux, but on the mux that is on the highest channel number (and therefore highest frequency) from Tacolneston (the HD mux excepted).
It may be that it is picking up another transmitter (namely the Norwich relay) and storing its muxes which are taking up memory. If this is the case, then the answer is to get it not to do this. You can find out if it is doing this by looking to see if there are any programme channels 800 upwards.
If these are from Norwich, then unfortunately the frequencies it uses are mixed in with those that Tacolneston uses. In some case, it is possible to have the aerial lead unplugged for part of the scan so as to stop the receiver picking up the wrong transmitter. How you might proceed depends largely on the operation of your box. If it allows manual tuning, then I would clear the memory by running it through with the aerial unplugged, and then manually tune in the five multiplexes from Tacolneston.
Re the other TV. What is the "fuzzy noise" you refer to?

Adele Dodgson: I should say that with it being the highest frequency, it will be the last one that the box gets to when it is scanning during the automatic tuning process.

Hi Dave,
Thank you for responding so quickly.
I have a Philips set-top box model number DTR 200/05 which I think I was given in December 2007 (or possibly 2006). The tv which this box is connected to is a Philips and at least 16 years old - I'm very impressed with its survival!
Having just checked the list (with all channels successfully present following a scan), the last Freeview channel in the list that I receive is 795 - Big Deal; so no channels from 800 upwards.
With respect to the fuzzy noise on the other tv, I mean the noise that you get without any signal i.e. no set-top box plugged in. This was expected as just prior to the digital switch over, I could hear the noise of the channels (e.g. the news) but couldn't see a picture. I'm wondering if I've made a stupid and obvious mistake (though I don't remember doing anything different) with this tv or whether a component inside the tv has actually broken?
Many Thanks
Adele

Adele Dodgson: I have located the instructions for your Philips box:
http://download.p4c.phili….pdf
I haven't found out what the memory capacity is, so I think you will have to try it and see. I am wondering if duplicate programme channels aren't put in the 800s on your model, but perhaps in the 700s.
What I would do is clear the channel memory by running the scan without the aerial plugged in. You should then find that the Channel List is empty. If it's not then delete any remaining channels (or there might be an option for this).
Having done that, use Manual Search to tune in the five multiplexes from Tacolneston. These are BBC=Ch55, ITV1/C4 etc=Ch59, ITV3 etc=Ch42, Pick TV etc=Ch45, Yesterday etc=Ch50.
Do that and see what happens. If it forgets the last multiplex to be stored, then that I expect that it is going to be ArqB on Ch50.
You might have to compromise and loose one multiplex, or perhaps you could delete some programme channels that you aren't bothered about within some of the multiplexes to make space. As I say, I don't know for certain and personally I would experiment.

Hi Dave,
Success - a very happy customer!
I followed your recommendations; wiped the channel list, did the the manual search for the five multiplexes and all the channels became available. I then switched off the set top box off (at the plug rather than standby) for two minutes and when I switched it back on again all the channels were still visible.
Many thanks for all your advice as well as finding a copy of the instructions for my set top box.
Adele
