Rex Watson:

The Sudbury transmitter transmits all 6 main multiplexes, so if your receive them all, you should get 122 channels BUT that includes 33 radio channels, and 6 HD channels (a TV/box with an HD/T2 tuner being required for them) and one IP delivered channel (the "Accessible" TV guide for which a smart TV with HbbTV connected to the internet is needed, the latter also needed to fully display LCN100 rather than plain text).

A reminder of what they are -
The 6 main multiplexes are on UHF channels C44, C41, C47, C29, C31, C37 that's in multiplex order -
PSBs1/BBCA, PSB2/D3&4, PSB3/BBCB HD, COM4/SDN, COM5/ArqA, COM6/ArqB
A "K" Groups aerial (T or wideband should do) would best to receive them all. If your aerial has not been changed since the analogue days it may be Group B and you might struggle with C29 & C31.

What you can receive will depend upon location, you may not be able to get all 6 multiplexes dependent on terrain, a full postcode would be needed to confirm you predicted reception.

The Sudbury transmitter has been listed for Planned Engineering for a few weeks now, so you may have experienced a loss of reception at various times and IF you tried retuning during those times or if you had badly pixellated pictures, it may have just cleared your correct tuning.
It is never advised to retune when you have no signal or badly pixellated pictures.
IF you did so and have lost channels you need to repeat a retune until you get the channels back. Arqiva have not advised if the engineering work has been completed.

I live in Shalford, Essex. My freeview antenna is pointed at Sudbury. When I do a channel search with my VU Duo 4k se receiver, it finds 145 channels. As Sudbury only broadcasts 122, I suppose that some of these (TalkSport, for example) must be on other masts which are in other directions. I am surprised that this happens, as my antenna is only a very small one, and is only 10 feet from the ground. On completing the channel search, my receiver sorts them into alphabetical order, and in the process discards 46 of them. I am thus left with 99 I can actually view, though only half a dozen or so of those offer material which interests me. I would particularly like to watch FreeSports, which is not on the Sudbury mast, of course, and wonder what prospect there is of doing so if I invest on a more expensive antenna.

Rex Watson: FreeSports is broadcast on the COM7 multiplex which is closing next month, so it really isn't worth changing your aerial to try and receive another transmitter. Nothing has been announced regarding whether FreeSports or any other channel will move to another multiplex or whether they will leave Freeview.

When BBC 3 was taken online and removed from Freeview , Channel 5 took their HD slot .
When BBC 3 returned to Freeview it got a HD slot , although Chan 5 , kept their slot,
How was this unknown , by me ,HD Slot suddenly available ? Why didn`t BBC4 get it or another , broadcaster?
Hopefully someone knows , it seems a bit sly to me, to hide it unused.

Richard Owen: Channel 5 didn't get BBC Three's HD slot, they just took over the channel number and used broadcast capacity that was previously vacant. BBC Three shares the same capacity that is used by CBBC channel up to 7pm in the same way that BBC Four shares with CBeebies. When BBC Three was closed, CBBC's hours were extended to finish at 9pm so there wasn't space for BBC Four HD to begin at 7pm and share capacity with CBBC HD. The spare capacity available after 9pm was offered by the BBC to other broadcasters however none were interested in broadcasting a HD channel that could only start at 9pm each evening. In Scotland, CBBC HD's hours were later cut back to finish at 7pm so that the BBC Scotland HD channel could use the capacity in the evening, similar to how S4C HD is now broadcast from 7pm in Wales, resulting in the the relaunched BBC Three only being available in HD from transmitters in England and Northern Ireland on Freeview (transmitters in Scotland and Wales on have the SD version of BBC Three).

I find it most odd that I can only watch 99 freeview channels, as the 122 channels from Sudbury are all at the same power. Any comment?

Rex Watson:

Apart from the fact you can't watch Radio stations! which channels are you not getting?
See https://www.freeview.co.uk/corporate/platform-management/channel-listings-industry-professionals for which channels are carried on which multiplex.

You have checked that you are correctly tuned to the Sudbury UHF channels? and Sudbury is still listed for Planned Engineering. See my reply https://ukfree.tv/transmitters/tv/Sudbury/PGSTART1770/irt1036227#b1036227

here on the east coast at this time of year we regularly get 'no signal' appear on screen. Why is it that the BBC and ITV multiplexes are the last to succumb to this?
