James, this isn't a website run by any authority, it is independently run. However, the answer to your question is that power on Sudbury is increasing again on 27th June. At the same time as the power increase, ArqB (the multiplex with those channels) will move from its temporary frequency of C63 to the final frequency of C56, which also is a lot easier to receive.

In the meantime, if you haven't already done so, replace the leads from the wall to the TV/STB etc with quality replacements. It may sound strange, but the signal lost through bad cables is often equivalent to the signal boost you would get from an aerial amplifier.

You can make cables yourself with nothing more complicated than a penknife, pliers and a small screwdriver. All of the cable and connectors are easily available from suppliers like Screwfix or Maplin. Make sure that you use double screened cable, something like the SLX PF100 which is available in white.

Nick: There was a requirement by Ofcom for the local muxes to be planned in such a way that the signal did not stray out of the intended coverage area! As radio waves do not respect county boundaries this was rather impractical, resulting in under-powered signals in some instances, whilst in others listeners are (fortunately) able to enjoy reception miles outside the target area. The D1 national mux has tended to target the areas of largest population and major roads, whilst the BBC is now trying to give good general coverage in preparation for the suggested FM switch-off. The latest Ofcom plans for local services allow for more comprehensive coverage in unserved areas to match the current FM service areas. I will be interested to see if the coverage of existing local muxes is extended to match the FM service areas of all the BBC local radio stations.

Thanks KMJ. I wondered why there were so many DAB transmitter, but not enough, whereas FM uses much higher power with far fewer transmitters. Daft rules again. They will have to get their act together before switching off FM.

g sawyer : assuming you are on Sudbury, over half of the channels are not on full power until June. Yesterday is one of those on ArqB on CH63 which most people cannot pick up properly since its switch from CH50 in November. Digital TV refused to accept this had caused a problem at the time, and eventually most people, like me, got fed up with complaining and are reluctantly sitting tight until June.

That should read Digital UK, of course. Or "I see no ships" as I prefer to think of them ...

G Sawyer, as Dale says, the channel that is used for Yesterday is operating at around 1/100th of the main channels. Not only that, but it is in a part of the frequency range that is right at the edge of receivability for most people's equipment. This is not a good combination and if you look back through this part of the forum you will see that the majority of recent problems are from people unable to receive Film4, Yesterday etc., all of which are carried on the same channel. This situation will improve in late June when there is a final retune which will move this channel to a better part of the band and will also increase the power to the same level as the others.

You haven't given your location but you said that you live 6 miles from something/someone. If you happen to live 6 miles from the Sudbury transmitter, then you probably have a different problem called desensitisation. In this situation, the high level of signal received from the more powerful stations swamps the smaller signals from channels like ArqB (the Yesterday channel). If that is the case, the solution is typically to successively cut down (or attenuate) the signal until you hopefully reach a sweet-spot and all channels can be received cleanly. Have a look at the page Freeview signals: too much of a good thing is bad for you | - independent free digital TV advice for more information.

John: It's due to happen on 27th June when a retune will be necessary for all Commercial channels as they all change UHF channels.
