Great Website. We live at NR20 5DE since the change over we have had to re-tune our living room TV about once a week (it tells us poor signal no picture). We have three TV's, a booster and the Ariel is on the chimney. Our son's TV needs to be tuned in every time he uses it even if he has been on the TV, then a DVD and back to TV- it needs re-tuning again. The other TV which is next to the booster seams fine. Any thoughts will be much appreciated. Thanks

Adelene: There are a number of possibilities and we have to be mindful that there might be a number of issues.
Firstly, the booster. What is its purpose? Does it provide three outputs, each one feeding a TV?
If it is a variable booster, then try turning it right down.
Have a look at this page:

It could be the case that (if the booster is used to split the signal three ways), that there is no need for it now (the signals are stronger after switchover). You might find that a non-powered splitter will work just fine.
Before you go down that route, try feeding the incoming aerial directly to one of the TVs and see if it clears the problem. If it does, then perhaps the problem is too much amplification.
Your son's TV; where a TV or box keeps "forgetting" some channels, it tends to indicate that the memory used to store channels is full and that those it doesn't remember won't fit in the memory. This is often as a result of the set picking up signals from other transmitters as well as the one that is used to view programmes. Because the automatic tuning scan goes from low frequency upwards, it picks up the lowest first. In the case of Tacolneston, it uses high frequencies, so the scan will get to it last. A first suggestion is to run the automatic tuning scan with the aerial unplugged for the first 25% of the scan. If that doesn't work, then we will have to see what other workarounds might be available.

Adelene: What is the make and model number of your son's TV? Some older models will not function correctly after switchover and we can check to see if this might be one.

Is Tacolneston transmitter having issues as we have had no BBC channels at all (other than HD)and frequent (almost permanent) channel drops on other channels since Monday? We receive the signal via a roof-top aerial.

Glen I have been watching BBC Parliament since 12.00 and I have just checked other BBC channels and everything appears normal. I have just done a scan and both the BBCA mux on 55 and all other muxes are coming through 100% signal strength and quality.

I live in Bury St Edmunds IP32 7DB and for over 5 years I have been getting Freeview from the Tacolneston transmitter. Until last year reception was perfect and reliable.
Then in the run up to switchover I would lose some or all channels for periods of a few hours to a few days. They would always return without my having to retune my set or PVR. I did retune when instructed to at the switchover dates but I continue to lose some or all channels from time to time - I get a blank screen which says "Digital channel strength is low" though the channel identity is shown at the top of the screen.
About three weeks ago I lost the ITV channels for a day or so and over the past weekend I first lost ITV, C4/5 and then at the very end of the Carling Cup final BBC1 pixellated and disappeared along with all the other channels and as of now- Monday 27/2/12 nothing has yet returned.
I cannot understand why this should keep happening. If it was a problem with my roof aeriel surely I would lose all the channels permanently, not just some of them, and why would they return suddenly without my doing anything. It seems to me the transmitter power must keep dropping. It is driving me mad!

Given the distance between you and Tac I doubt it is signal strength that is the issue. Digital is going to highlight more issues with cabling. Winter will see greater stresses on the aerial (hot/cold expansion) and what was OK with analogue begins to cause problems with digital.
I would suggest a visual inspection and then I think you might have to bite the bullet and get in an expert.
You can get issues that only impact on certain frequencies - it can be an odd situation.
Are you also sure it isn't Sudbury you are using or is your aerial pointing towards Norfolk? If you want to DIY it I would suggest a log periodic aerial (the BBC used them for their relays!) or a Blake DMX-10 wideband. Personally I'd go for a Blake DMX-10 wideband as it can really pull in a signal.
I don't have any affiliation with anyone - I just teach Physics...

Ken Illsley: Further to what's already been said by J and just to add to this, on the issue of where you are actually receiving your signal from select BBC1 and go into the signal strength / quality checking screen and note the Mux Channel number thats indicated associated with the level seen, if the signal is from Tacolneston it will be Ch55 whereas its Ch44 if from Sudbury, then select ITV1 and carry out a similar test, Tacolneston being Ch59 whereas if Sudbury its Ch41.
Just as a final confirmation check on a non PSB transmitter, select ITV3 and carry out the same procedure as before, Tacolneston SDN being Ch42 whereas its Ch49 from Sudbury, although as its temporarily running on low power you might not receive it anyway.
