Chris Gardiner: Arqiva B has been on low power from Sudbury since November and as a result has been difficult to pick up. Perhaps your signal level has dropped just below that which your receivers will work (perhaps due to some external change which is therefore likely to be beyond your control).

Chris Gardiner: I have also lost Arq A today for the first time since November. Strangely Arq B which is on a lower signal is working fine.I am in south Essex.

Have also lost channel 63 again tonight.
It was going OK yesterday here.
Now its just a right mess.
I find Channel 39 from Bluebell Hill way strong this comes in at 70% all the time channel 63 was 40%

k: If the reception of every channel has failed its much more inclined to suggest that your aerial system has developed a fault, and so I would check the co-ax cabling as far as you can manage to.
There could of course be a fault with the TV's tuner, but that's not so likely a reason for your problem, cant you borrow a Freeview box for an aerial test?

I live 9 miles from the Sudbury transmitter, not close enough to suffer invrsion from any other transmitter. I have had Freeview via integrated tv for four years. The switchover all went fine, until the final stage, after which I lost a group of channels that include Film4 etc. - I see they are all in one multiplex, and others have had problems with this. Up until the switchover all was fine, so how did it cause me to lose channels? I don't want to have to pay for a new aerial when its not my fault I lost them.

Phil, I'm certainly no expect in these matters but here's a couple of ideas that may assist as I live in Chelmsford and pick up all mux's without problem from the Sudbury transmitter.
What seems abit strange is that ARQB is showing on my receivers as the strongest signal but with a slightly reduced quality. If you're in the same situation are you now receiving to much signal? Secondly is your aerial a wideband? As ARQB is currently at the top end of the channels the wrong band aerial might cause your problems.
As I say just thoughts, but I'm sure others will have more informed ideas.

Phil: I would check out the suggestions on the Single frequency interference | ukfree.tv - independent free digital TV advice page, as the services on Sudbury should all be working perfectly for you at your location.
