The list of Freeview transmitter changes 2017-20 Upcoming Freeview transmitter changes 2017 to 2019 states that PSB1, 2, and 3 will remain on their current channels after next year. The table above indicates that they will move. Which is correct?

thanks, Mike P.
There seem to be several empty channels. It is a shame Al Jazeera does not use one.

I think I have checked everything . My question is why am I receiving Meridian Local news on 103 HD from the Sudbury transmitter ?

Mr Paul Bradley:
The HD services are not currently available with regionalised news services, so the broadcasters are using a 'general' setting so there are not any blank screens. Local regional services are available on the SD versions, on channel 3 for example instead of channel 103.
It is expected that when the forthcoming alterations to transmission arrangements take effect then the broadcasters have the opportunity to 'regionalise' their HD offerings.

I have a high gain triple boom aerial on a pole attached to the rear of my property approx 20ft above the ground pointing to the Sudbury transmitter..
All channels work except for the bbc channels which keep breaking up. if i point the aerial to the local transmitter they work fine but of course i cannot get all the other channels.
I have a 4G filter fitted and have tried all the reseting and retuning options available to me without success.
I suspect my aerial is picking up both signals from both transmitters but have no idea how to overcome it if that is the case. I have searched the net without result except some suggestions that this may be the case.
Hope you can advise.
many thanks

David Thorne: Firstly, have you checked that your TV is tuned to Sudbury on UHF 44 for BBC channels rather than Clacton on UHF 49? Also, what signal strength and quality readings do you get? According to the Digital UK checker, from next summer the Clacton relay will be gaining the COM4/5/6 multiplexes so in the long run you would probably be better off turning your aerial around, particularly as reception of Sudbury appears to be getting worse at your location from 2019.

Hi,
I think your table for "How will the Sudbury (Suffolk, England) transmission frequencies change over time" is incorrect for the right hand column.
It shows all muxes changing on 31st March, which seems to contradict the Digital UK and Ofcom information.
Ofcom shows that the channel allocations will eventually become:
PSB1 - 44
PSB2 - 41
PSB3 - 47
COM4 - 29
COM5 - 31
COM6 -37
(from https://www.ofcom.org.uk/…lsx)
But doesn't give any dates for the change(s)
The DigitalUK site says that the only currently definite change is tomorrow (7th February), not the 31st March, and that it is only COM6 that is changing at this stage:
http://www.digitaluk.co.u….pdf
It is probably worth updating your page to prevent alarming people that all the PSB muxes will be moving to frequencies not receivable with an old "Group B" aerial!

I sincerely hope the channel changes shown here for March are incorrect. Having invested in a new aerial and a freeview recorder box, it would appear that my aerial which is designed for the former group b and c will not get the main BBC and ITV channels which appear to be moving to a group A aerial.

I think it is a liberty to make people invest in new aerials to receive freeview and then a few years later change the channels used so that yet another aerial is required.
If the latest changes result in viewers being unable to watch their tv's because the broadcasting channels have been moved to a different aerial group, is there a body we can complain to?
In my case a wideband aerial was not good enough, I specifically needed one biased towards the muxes on channels 56, 58 and 60 which were weak. Now they propose to move the channels out of aerial group, to the opposite end of the available frequency bands, around channel 30!

nick horrex: Anyone who relies on their aerial for reception (i.e. doesn't have satellite or cable) will be eligible for a free replacement aerial if they loose any of the PSB1-3 or COM4-6 multiplexes as a result of the 700MHz clearance changes (provided the existing aerial is in good condition and not damaged etc). The link below gives details of the Freeview Advice Line who will assist anyone who finds they have channels missing following any frequency changes at their transmitter and will arrange a free of charge engineer visit if the missing channels cannot be restored by talking the viewer through a manual retune.
