hello
We're at IP6 0LQ, and haved lost all channels on ArqB this weekend. We receive our signal from Sudbury transmitter, and have been trotting along fine for ages now. We've had all aerial, cable, connectors checked recently, and are currently having no issues with any other channels. Anyone else out there having the same issues? Have tried a manual retune on 63 and 50, 51 & 52 and "no channels found". Thanks

Elaine: Its pity that you carried out a re-tune as you will have lost ArqB on Mux Ch63 from the TV's / boxes memory as otherwise I would have requested that you to carry out a signal strength check whilst on ITV4 etc, because its likely that the signal had just dropped under the reception threshold level and which would have returned when the it lifted again, as the signal level will still show even although there is no picture.
The reception predictor (trade view) isn't really of any assistance on your particular area code either, as it in effect indicates that you are in a black spot for reception from Sudbury and with no reception from commercial muxes being possible until June, so even although you maybe can receive them there has to be an element of pot luck about it as they are very low powered, so about the only thing you can do is to keep trying a manual tune on Ch63 every few hours until it returns to a level that the receiving equipment can lock on to.
By the way, the commercial multiplexes such as one of that's causing problems, wont be switching over to high power until June 27th when a re-tune event takes place.

I am trying to assist some friends who live in Jaywick, Essex and after DSO last year lost some channels that they could previously receive OK.
They are definitely served from Sudbury (despite the freeview reception site that says Dover) and all neighbours aerials are pointing that way as well.
Based on my experience (from Tacolneston) I advised them to remove their aerial amplifier and re-scan etc. but it didn't help.
The "main 4" are OK - sorry but I don't know which ones they are struggling with so will try and find out & update this post.
thanks

David,
Sudbury isn't up to full power on all channels, unlike Tacolneston which is now full power on all channels. This is due to the proximity of Sudbury to the Dover area and the need to wait until they have switched over.
Either they should wait until June 27th, or spend time on tweaking the simplest parts of their system, i.e. make up good quality leads from quality cable and bin any cheap leads bought from DIY stores etc.

......further investigation reveals that the channels they cannot get are all on ArqB mux - iu.e. the one that is running on lowest power so yes, they will have to wait until Dover goes DSO........still wondering why the freeview site seems to think they are served from Dover though.
Never thought I'd be saying I'm glad WE are served from Taccy :)
Thanks for the reply anyway

@david,
You probably changed your location when you were checking the location of your friends. Just set it back, there's no problem.
Updates are only sent out once a day so as to not 'spam' people's inboxes if they are getting updates from multiple busy topics.

Since the switchover we seem to have lost a lot of channels. I used to get about 120 and now we get 80. In particular I have lost Yesterday, which I used to watch a lot. Does nayone know why this is?
I am in Halstead and use a TV with a built in Freeview via an old aerial. But surely if it worked pre-changeover the signal should be better now, not worse.

John: Two of the multiplexes at Sudbury are operating on very low power compared to the main PSB ones, with these being the ones used by the programme channels you have complained about. Unfortunately your problem will not really get any better until June 27th when both of them increase power at the same time as the re-tune even that takes place on that date.
