Hi. Rachel I have the same problem, according to other people on this website it will last until May of next year when there is another retune. But I am hoping that if enough people conplain, they might do something about it. You never know a miracle might happen.

The next retune is in November maybe that will help. I'm in a marginal area for Sandy Heath too - the digital switchover is turning into a bit of a disaster for me too with the final signal strength, when it's all completed, prdicted to be worse, not better! My only option then to get all channels will be to go back to Sky - grrrrr.

Hi. That is true, but we will have to wait until next year as Channel 31 is not moving until then. If you don't like Sky, why not try Freesat which is just as good if you don't want to pay.

Just for information ITV HD and ITV1 + 1 is Meridian South East not Meridian Southampton, that is not to say the programme is not originated in Southampton, the news coverage however, is related to the old Dover transmission coverage i.e. Kent and east Sussex area.

Thanks Alan, yes Briantist also told me that Freesat was an option but some channels you don't get on that.
I think I'll wait and see how things go for a while, if the signal I'm getting degrades further then I'll have to go for one or the other.

Is anyone else noticing since 14th Sept "Challenge" is appearing on two muxes - one is incorrect? Made a mockery of retuning as it keeps slotting the incorrect one in on the right channel, and sticking the "real" one in up on 801. On all my TV's. And my neighbours. And parents.

Eric Half Bee: For any given transmitter Challenge is on Mux C only (therefore only one version per transmitter). It looks like your TV/Box is picking up Mux C from another transmitter as well. If you are in the Central or Yorkshire regions switchover has been occuring throught September, and power levels on transmitters has been increased which explain the transmitter overlap effect. A manual retune frequency by frequency should fix this.

Hope this helps,
Adam.

If I were you I would try and wait until ASTRA 1N comes on stream, because I read somewhwere that Five USA and Five* might join along with other channels. But this has NOT been comfirmed.

I live to the north of Luton and channel 31 has been wiped out completely which means no CSI on 5 USA. Sandy Heath is north east of here with Crystal palace to the south south east. I was wondering if I could shield the aerial on that side with some wire mesh and tin foil and ground it I would be able to block out the crystal palace signal (the aerial is in the loft). Might be a project for tomorrow if I'm not busy
