The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Oxford (Oxfordshire, England) mast?

Jody: It's because the TV which has not done the swap pre-dates the capability to do the swap!

Changes to BBC HD channels as Freeview HD swap rolls out > RXTV info

The capability to replace SD channels with their HD variant has only been devised and made available in the last few years. This is as a response to the obvious, which is that the HD variants should take up the logical channel numbers of their SD counterparts where they exist (instead of languishing in the 1xx range). When the system/standard was devised in the first place, this wasn't thought of and was not an issue or requirement.

Thanks for the info but the TV is only 18 months old. It is a Samsung. I've been doing some reading since I posted earlier and think it might be do do with the TV not having freeview play, only freeview. Read somewhere that Samsung TVs don't have freeview play.
I just hope that in the future, if BBC SD gets retired, we won't end up with channel 1 being empty and having to go to 101 just to watch BBC

Here's another interesting technical article about Freeview Play HD channels

You are quite correct that it has do do with the set being compliant with Freeview Play specifications and so having Freeview Play. Your set should have a "Channel Manager" somewhere in Settings which would allow you to swap channels around to suit your own requirements.
On some sets/makes you might have to do it by using a "Favouites" feature.
In any event I would expect Samsung to do a Firmware update at some time which will take care of such "swaps" in the future to avoid LCN 1, 2 etc being left vacant.
It will be some considerable time yet before SD channels on Freeview are closed down, there are far too many SD only sets still in use.

Chris.SE: Thanks for the link Chris. It's a shame it's not built in to the DVB standard as it would seem a useful feature which produce the sensible result of having BBC One HD on LCN1, BBC Two HD on LCN2 and so on, now that the programming of SD and HD are identical.

Yes it's annoying. I've used my Channel manager to move my HD channels to 1, 2, 4, 5 but not ITV as it hasn't yet implemented full local regional news - still only 4 main regions (+ STV, UTV & ITV Wales). I've put the SD ones in the 900s so any (manual) retunes don't mess things up.
It's also irritating that doing a basic search I can't quickly find the BBC web pages that covered the changes, there were some but I don't recall where they were. One shouldn't have to rely on other independent websites for the information (and sometimes there can be errors or misinterpretations)!

Annoyingly my TV doesn't have an option to move the channels. The edit channels screen only has the options to lock and delete a channel. Has 'rename' as an option but even that is greyed out

My set doesn't have the option direct (not a Samsung) I have to renumber.
I renumber the SD ones first to clear the LCNs.
So I did 1 to 901, 2 to 902, 4 to 904, 5 to 905, 9 to 909.
Then 101 to 1, 102 to 2, 104 to 4, 105 to 5, 106 to 9. I also did 107 to 8 as 8 is clear - my Local station is on 7, also 23 is too much hassle (2 key presses :o )

PS. Posts sometimes take a while to appear, so wait a minute or two to avoid a double post.
