jb38: Thanks for the reply. As we know, the public face of Digital TV would have us all believe that the switchover would be easy, and everyone would get a wonderful service. But spending a year or more on this forum has shown me what a difficult job TV and aerial installers are having, dealing with a multitude of different situations.

Was there an outage yesterday?

I lost Film4 and Dave (ArqA and ArqB) yesterday around 6pm, both from Sudbury and Tacolneston. This was experienced on 2 different TVs and with separate aerials.

having been brought up in Liverpool in the 60s with no football match having less than 44 players, at the start, due to horrible ghosting I was more than pleased when the same old aerial in my mother's house produced perfect Freeview pictures post Granada switchover.
So it was with great anticipation that I looked forward to the switchover in Chemsford (CM2) and wasn't disappointed until..
I didn't figure out why I lost channels when Tacleston switched, I only know now through this august website.

I do feel as though I've been short changed despite also having Sky etc downstairs I do rely on Freeview around the rest of the house and for PIP on my main TV.
I feel sorry for those who totally depend on Freeview, none of my equipment is older than May 2011, seems like poor planing and communications from the switchover team to me.

Brian O'Keefe: You will have to wait until 27th June before the missing channels become available to you again.

Because of the way things are run these days, 8% of the population won't be able to pick up any of the commercial channels using a terrestrial television aerial. They will be limited to the Public Service Broadcaster (PSB) multiplexes which carry BBC TV and radio, ITV1, ITV2, C4, E4, More4, C5, HD channels and a few others.

Some others will be restricted to the PSBs unless they have a different or extra aerial fitted.

This may be the definitive answer.
A OAP friend of mine in Sudbury who has problems with C63, annoyed by the lack of interest with the Freeview Help Line wrote to all and sundry about the unreliable reception, ie BBc, OFCOM, Freeview etc
Well you may think what a waste of time.
However this morning an engineer travelled all the way down from Peterborough to visit his premises and test out his installation.
Sure enough when he arrived C63 was pixelating
After spending some time with test eqpt he told the owner, "there was nothing wrong with his installation which included the aerial on the roof"
He would return to Peterborough to inform his masters that the fault does not lie at the customers premises.
The only other place left is the Mast then ?

Are the frequencies shown on this page definitely correct for Sudbury as of today 7/1/12? I ask as I am trying to make sure I get a Windows Media Centre set up correctly and the frequencies here seem to contradict what the Ofcom switchover document says:

BBC A Ofcom: 44 here: 44
D3&4 Ofcom: 41 here: 41
BBC B Ofcom: 47 here: 47
SDN(A)Ofcom: 49 here: 49 (will move June 2012)
Arq A Ofcom: 60- here: 54
Aeq B Ofcom: 56 here: 50+

As you can see you disagree on Arq A and Arq B.

I can see so many signals where I am (aprrox 10 miles North of Sudbury) that signal strength at any moment is very variable so I want to tune to the definitive signals off Sudbury which is on average the most reliable signal.

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):….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?
