Rod Roberts: The overall signal levels have been increased this week as well as the changes to channels. I suppose it's possible that you could have too much signal, although I would have expected that to affect the more powerful multiplexes, not the weakest.

Rod Robert:
As Mike has suggested, you might be getting too much signalnow that SDN's power has gone to 100Kw.
Try taking your booster out of circuit to see if that makes a difference.

Hi
I live at BS15 and I cant get any of the channels in MUX48 at all. Ive retuned umpteen times manually and automatically. Ive rang the digital switchover people and have been told that i "should just keep trying as it make take 2 weeks before I can get them as work may still be on going" - is this correct?

If Digital UK told you that, they are talking complete and utter rubbish. Thge changes went fine and are complete, everything is working.
Try a full factory reset of your equipment & new installation scan with the aerial unplugged and the plug the aerial in and do a new installation.
See the link for the Freeview reset procedurein the yellow box below for more detail.

Craig: In addition to my suggestion above, the power has now increased on the SDN mux on C48. It is possible you are getting too much signal. If you are using a Booster/Amplifier try taking it out of circuit and try again.

Thanks for that - already tried the full reset/retune without the aerial plugged in. Guess will have to try getting a attenuator. I live in a block of flats with communal aerial so I dont know if there is a booster/amplifier fitted. When you go to MUX 48 the Signal shows as Nil and the Strength shows as Nil as well.

Surely I'm right when I say those transmitters, likely for interference with others are operating different signal powers have completely messed up, for those who live some distances away.
Guess depends on distance, but lets say few years back, Mr X and family have Aerial installer put in some X high gain aerial with masthead amplifier on.
Lets also say they live maybe 20 plus miles from transmitter, and lets say they got about, oh I don't know 80% signal Strength or more and 80% plus quality.
Now, Bang, switchover comes and power gets boosted, good for the fringe people like me, fringe cause of the dip and hill in way etc.
But Mr X is now told, online on some site like this, too much signal.
So he buys an attenuator.
Ar ha, here we have a problem.
Before switchover we have all Muxes on say 8,000 and now public ones are on say 50,000, like Waltham, but hang on, we have SDN and Aqiv on less than that, oops.
So by reducing, and getting back the BBC and ITV, he now starts to lose, or get break up sometimes on commercial ones.
I could be wrong, but that's my thinking.
This is why Sutton Coldfield, despite initial problems some seem to be having should work out better, as all are on and at 200,000 kws.
