Michael: Even although you have reported the digital TV (also Freeview?) as being fine this could simply be because of it having a more sensitive tuner coupled to it also having slightly better circuitry, (e.g: Panasonic TV's / Humax if a box) or alternatively that its aerial feed might be supplying it with a slightly higher level of signal, this totally dependant on whatever method you use feed the aerial into both devices and that both devices are definitely tuned to the same transmitter.

As far as Digital TV is concerned, its inevitable that if a TV system is changed from one like analogue than can produce a picture of sorts right down to an almost zero signal with one than "has" to have a certain level of signal before anything can be heard or seen, that the latter is bound not to cope with serious fluctuations in signal levels caused by seasonal atmospheric changes and such likes which can allow signals to be received from far off places that can clash with local transmissions, this being something that has always happened albeit that analogue can cope with this in a much better way.

One last query, security is security but Olympic games would you know if there would be any external interference of any kind that would disrupt the freeview signal that would be attributed to extra pressure on let's say bandwith due to the Olympics. In other words would you be informed of any external factors that would block my London signal that is not entirely due to the transmitters.

Michael: Chris's point had also occurred to me. I know red button services have been amended but if the standard signal has been degraded, that's been kept quiet. I can't think of anything more likely to hack off Londoners than making it difficult for loads of us to view what our extra council tax is paying for (yes, I know general taxation funds a lot of it too).

Yes, the digital TV is Freeview too. I have moved that to the location of the HD recorder and it performs fine .. unless of course I feed it the signal from the HD recorder! Similarly, I moved our stone age Freeview box upstairs to the location of the digital TV. Didn't change its performance.

I think the difference has to be the quality of the tuner. The digital TV seems able to cope with lower signal quality and - perhaps just as importantly - substantial variation in signal quality that we are experiencing. Typically, the signal strength is solid at 70-75% but the quality is either down at 30-40% or constantly shifting sharply within the range 10 to 70%. The exception is when the box decides it fancies Heathfield or Bluebell Hill for BBC and/or ITV, when signal strength also drops to 40-50%.

One last point is that some of the similar complaints from people in other parts of London have come when our signal is OK.

Overnight we have lost all channels associated with multiplex A & D. I am at a complete loss for what to do as this a large chunk of Freeview now gone. Any advice greatly appreciated. We have until this happened always had great reception.

Michael: We have usually ended up deleting all channels on our HDD recorder (by retuning with the aerial disconnected) and then manual tuning the five multiplexes we are supposed to get from Crystal Palace. This usually gets back the BBC and ITV muxes but does not improve the other three - however deleting everything first does semms to prevent channels being numbered 800+.

It looks as if the Crystal Palace signal is weak at 8am when our HDD recorder auto retunes, so you may have to pick your time.

Even so, tonight's Olympic joy was slightly diluted by watching pixellated atheletes, even on the BBC signal from Crystal Palace. I expect they will get well pixellated in the next few hours though...

A first yesterday was to find one of the muxes claiming to be 698KHz, which appears to be "Waltham" - is that Walthamstow North? Previous "wrong""ansmitters have been Bluebell Hill and Heathfield.

I want to know whom I should be complaining to. The whole thing seems to be secretive and accountable to nobody.

David Taylor:
Hi Guys,
When Freeview Digital was first started I
purchased a box but got "no signal" message
(see original posts)
After full switch over all worked ok, except I had to buy two new TV's.
My house is in a dead spot and analogue
reception was never very good.
Yesterday I turned on TV and we were back to
the state we were in before, with no signal
messages and frozen picture etc.
Nothing has changed with my aerial etc.
Have they reduced the signal strength?

Dave Taylor: I have read back your postings.

I have observed that the White Oak Leisure Centre could be in the (or under the) signal path at 850m away (just over half a mile). I mention this because it appears to have a large metalic content.

This terrain plot shows that you could have line-of-sight, assuming no obstructions:

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

Perhaps the poor reception at your location is caused reflections that are acting to reduce the quality or signal strength.

Thanks for reply
What I can't understand is why I've suddenly
lost the signal unless the power from the transmitter has fallen.
Could well be White Oak Centre causing a
dead spot.
Don't have line of sight to transmitter as
I'm down a dip.

I have had "no signal" coming up for the last three days, I can not get any channels at all, my aerial is brand new as is my freeview box, it says on the websites that the crystal palace transmitter is off air, but only on the 9th of August, please could someone tell me if I am doing something wrong or if it is a fault that I can not fix myself and if so, when will this be fixed

Bonnie: Where is your aerial located? my only reason for asking being that "if" (as I realise you might not) you reside in the beige brick properties then the aerials mounted at each end of them appear to be of a communal nature serving the apartments within each block, and as such obviously out with your control as far as doing anything is concerned.

However the reception predictor indicates Crystal Palace as being able to provide a good signal at your location, but though the aerials referred to appear to be pointing towards Guildford and likewise mounted vertically, and although Guildford is also indicated as receivable at your location its not quite at Crystal Palace levels.

That said, if your box has a manual tuning facility then for a test go into the tuning menu - "manual tune" and enter Ch23 (BBC from Crystal Palace) then press search or scan and see if anything comes up, if not change to number to Ch43 (BBC Guildford) and carry out the same test, giving an update on results.

It would also be of assistance to know the brand / model of box you are using.

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.
