Hi, am going to have to be a bit vague with my question, but would appreciate any help you could give me.

My daughter has moved to Bishops Stortford, taking a Logik Digital TV, (previously used in Worcester). She tried to set it up yesterday but could get nothing, just messages saying how poor the signals were. She has tried resetting the TV and tuned the TV several times, with no result. I notice from previous posts that there seem to have been a few problems in the South East, so was wondering if there are still problems with the signal, which will be rectified at the time of the changeover, or is it more likely to be due to an inadequate or faulty aerial? She is currently having to use the analogue signal, which is quite poor. Please help!

Pat Brock: In general terms, the digital signals for Public Service Broadcasters (PSBs) after switchover will match that of the current analogue.

Transmitters serving the Worcester area have switched fully to digital whereas those in Bishop's Stortford have not and are therefore on low pre-switchover power or, in the case of the Bishop's Stortford relay transmitter, does not carry digital at all yet.

One thing is for sure and that is if your daughter's aerial is directed at the Bishop's Stortford relay transmitter which is on Rayners Road Industrial Estate (the aerial will be vertical), then she will not be able to receive (certainly reliable) Freeview before switchover and after switchover will only receive PSB channels.

If analogue reception is poor, then this could be because the TV has tuned to the wrong transmitter. That is, if the aerial points at Bishop's Stortford it could be tuned to Crystal Palace (or another transmitter) or vice versa.

If your daughter's aerial is on Crystal Palace, then hopefully it will be OK. I would suggest that it is best to wait until April because the current aerial may work fine come switchover.

andy: From 18th April Crystal Palace will be a full Freeview transmitter. There will be no services on low power to protect against interference from other areas (that have not switched over yet) as has happened with Sudbury.

I'm genuinely indebted once more (as always) for the technical explanations advanced by FJC Farrar. I have no doubt they are all sound, and you appear very well informed. My question remains, why since 25th Feb (or thereabouts) have people scattered all over London been losing their Freeview channels if nobody had any hint that this might happen? (mine are down again this evening). The switchover process has been under way for some time throughout the UK, and unless each team that carries it out treats it like a state secret, there will be a body of information borne of experience, that shows them to expect that some people will be affected adversely during the process.

A while ago Digital UK sent out a leaflet to my address titled "Is your flat ready for the TV switchover in April 2012?" I have every reason to believe this is a national campaign, not something they have just favoured me alone with. On it they listed two points to check. An extra line of text as point three could have warned people that they might experience erratic reception as they approach switchover, so don't rush out and buy new equipment until the process is complete. It isn't quantum physics to do this, but there appears to be an attitude prevalent that this is "nothing to do with us, Guv". Oh, and if you happen to buy new equipment needlessly because you lose Freeview access and don't realise it is temporary, hard luck.

Science marches on.

I've just used the new Reception Prediction System and for reception at my postcode from the Crystal Palace transmitter, the model is predicting low signals for Muxes 1, B, and C (which I can still receive) and lower signal strengths for Muxes 2 and A (which I cannot receive). So the model predicts the relative levels correctly, although of course it doesn't provide the propagation model algorithms, so actual receiver levels cannot be tested or compared to the receiver equipment figures (the TV reception signal levels are probably only guides anyway and I don't know the aerial gain). Therefore, simple propagation loss seems to be the answer and not interference, which cannot be calculated without knowing my aerial characteristics. I hope this model is available post switchover, so I can confirm the situation then.

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.
