Martin nr Sudbury: It would appear that the channel numbers for the three commercial multiplexes shown at the top of this page as being "after Wednesday 20th July 2011" are in fact those which will be adopted on 27th June.
Here is the trade newsletter from Digital UK on the retune of 16th November (it details the upcoming changes):
http://www.digitaluk.co.u….pdf
SDN Ch49 to move to Ch58
Arq A Ch54 to move to Ch60
Arq B Ch63 to move to Ch56
(These moves all due to take place on 27th June)
The Arq B on Ch50 will be from Tacolneston. Since the change to Ch63 in November, it has proved very difficult for many to receive. There have even been reports of people within a few miles of the transmitter having issues.

A query, just out of interest.
I'm receiving all Mux's loud and clear (lucky me some may say!) However the signal strength and quality shows roughly the same across the board, even though some are transmitted with up to 100 times greater power than others. Do the freeview receivers have some kind of compensator built-in to allow for this difference?

I've lost reception on all the COM5
ArqA channels on Sunday, having always had clear reception. Could this be a weather related issue?

States nothing wrong with Sudbury transmitter so can anyone tell me why when we retuned we ended up with Calender news which I gather covers Leeds area instead of Anglia news

Pat B: Because your TV tuned to the Belmont transmitter which is in Lincolnshire or Emley Moor in Yorkshire. These signals came available to you so far away due to the inversion effect.

Pat B.Clacton-on-Sea.If has you stated you received Calendar News,if this is on frequency 25 then yer signals due to inversion effect will come from the Belmont mast,if on frequency 44 from Emley Moor.Look up inversion effect,this is the cause not a transmitter fault at Sudbury mast.

Pat B.I forgot to add if yer receiving Calendar and its from Emley Moor (D3+4 mux on fr 44) you may temporarily until inversion ends find that it clashes with Sudbury's BBCA mux also on fr 44,causing potential (temporary) loss of signal on that multiplex.If the Calendar news is on frequency 25 (D3+4 mux) it comes from Belmont transmitter.
