How do I know if I am getting my signal from Sudbury or Rouncefall? They are both transmitting on the same channels / frequencies I believe?

thanks

Thanks Mike : I had researched all of this a lot over last few months, and had spotted some potential 'quirks' in this area which I have endeavoured to pass on to friends/colleagues e.g. unlike most transmitters, Sudbury switchover necessitates a (probable)change of aerial from Group B to Group E or W, particularly come November 2011 and then June 2012 ; but had not picked up on the temporary channel duplication.
Will check that I have the stronger version on Channel 9.

Cheers!

Mike : C56 from Sudbury B provides Mux 2 to the east of Sudbury (including those of us in Ipswich) until 20th July. C68 seems to only radiate to the west of Sudbury : we can't pick it up here in the east.

Lisa: You are getting BBC A from Sudbury *and* Rouncefall. That's the way it now works. The signal from both transmitters adds together and (hopefully) produces better results than from one transmitter alone.

The exact influence each transmitter has depends on exactly where you are and which way your aerial's pointing. Digital UK's predictor (trade view) shows the prediction only for aiming the aerial directly at one transmitter or the other, but signals from both transmitters, plus the interference from all other transmitters, are taken into account.

Thanks Mike. I am very pleasantly suprised to be getting 95% to 100% quality and strength from Sudbury region as of today (Channel 44), when I am on the fringe of both Sudbury and Crystal Palace and my aerial is pointing at CP. I did have an aerial installer booked to come and point my aerial to Sudbury on 21st July but I have cancelled him for now as I think I may be okay with it as it is, and that leaves me the option of getting better reception from CP after London DSO from April 2012.

Or, have I overlooked something and all is not quite as rosy as it currently seems?

I have reset and rescanned my digital TV tuner but the BBC signal is so weak it is not registering. It is fine on my DVR. Will BBC signal be boosted soo?. I'm in IP31 which is supposed to be Tacolneston but nearly all the village is on Sudbury.

Steve Wilson: If your aerial is pointing at Sudbury but the TV can't detect the BBC multiplex, either the TV doesn't support 8K mode or the signal is *too strong*, not too weak.

The new digital signal level for BBC A is over 14 times the previous level for Mux 1.

If you have a booster or other amplifier, remove it or turn it down. If that doesn't help, try adding an attenuator.

If you're connecting the aerial input of the TV to the RF output of the PVR, consider splitting the downlead from the aerial using a splitter, and connect each device to the downlead separately.

There is a partial list of equipment known to have problems with 8K mode at http://www.digitaluk.co.uk/2kequipment .

Hi Mike, thanks for that. When connected direct to the aerial, the BBC channels will tune but they are unwatchable due to breaking up. According to your list my TV is not 8K compatible - I don't remember that being mentioned in the TV campaign! Thanks again for your advice, I was looking for a new telly anyway.
