Rob:
Thought is has yet to be officially confirmed, I understand that the 700-800 MHz range is set to be 'sold off' so the spectrum could, perhaps, be used for 4G or 5G mobile usage.
Transmitters, like Oxford, that currently broadcast at least some of their signals will be adjusted so that they transmit at lower frequencies. That is why we have oftem suggested people have either a Group K aerial, which covers all of the Group A channels as well as most of those in Group B so will be capable of receiving all the channels after the adjustments, or else have a log-periodic aerial which covers the UHF TV spectrum so is suitable for the current frequencies as well as all those envisaged in the foreseeable future - subject to Ofcom's confirmation of course.
That is likely to be the situation for next 5-10 years but after that there could be more major changes but that is open to speculation at present with no firm 'hints' coming from Ofcom.
So, do not worry about loosing your Oxford signals for a while yet.

I have an unusual problem. I have a Humax Freeview HD PVR downstairs and a TVonics Freeview HD PVR upstairs, off the SAME professionally installed roof aerial.
The Humax now tunes to the Oxford Test Transmission on Channel 8.
However, the TVonics box does not. It has BBC3 on 7 and BBC4 on 9 but manually selecting channel 8 reverts to BBC3 on ch 7?
I have updated all software for the TVonics box and factory resets as well as multiple clearing of channels and retuning. Nothing will bring the Ch 8 Oxford Test transmission up.
Any explanation would be welcomed, please

Jon Dennington: l have TVonics PVR, I had to do a manual tune. Remember the LOX multiplex is on channel 29, not 51 as stated on this web site. Despite low signal level it works ok here in Swindon.

Thanks for the quick reply. All other devices off this aerial pick up ch8 on 29. My Tvonics is a DTR-Z500HD and even after a channel clean and reset, on manual tune 29 (or 51!) still shows no signal and no channels.
This reminds me of the necessary Vestel chip upgrades via serial cable on the Digihome type boxes I helped with a few years ago when certain muxes could not be seen after a transmission change!?
If I take the aerial out of the PVR and put it directly in the attached HD Freeview TV then 29 picks up ch8 so not a signal strength issue?

Jon Dennington : Purely out of curiosity, although you may well have cleared the channel list followed by resetting the box, but did you try disconnecting the box from the mains supply for a short period (3-5 minutes) before powering it up again and carrying out the retune?, as this latter action is necessary on some devices.
On the subject of the software update, does this refer to V3.0 A2950.D390.F102 ?, which I believe to be the last issued by Pulse-Eight on 21-6-2013.
Another point being, that it cannot automatically be assumed that there isn't a signal issue just because the TV picks C29 up when the aerial is coupled directly into it, as all tuners vary in sensitivity, and so it all depends on what the strength and quality level is being indicated at on TV when on C29?
Although this isnt the best week to be carrying out signal checks from Oxford, as engineering work has been taking place since Monday, likewise odd things might happen now and again.

The BT digibox which we have installed, and our "Freeview" Sony Bravia has shown that many commercial programmes are moving channels (with no indication as to what the new channels are. We have been without these ITV and commercial channels for about 9 days. Re-tuning the BT box has not changed the situation.
I would like to know, if this is due to changes at the Oxford transmitter, or is there a fault with our TV and/or BT Digibox? If the transmitter is having changes in transmission of channels, is there any indication as to how long will it take? Will the new, changed ITV and commercial channels be advertised, so that we know where to look for them? Thank you for your help. Regards Colin Flindell.

Colin FLINDELL: The undermentioned link explains the reasons for the changes, the question being, did you try retuning the TV?, if though you have and yet channels are still missing, carry out a manufacturers reset on the TV followed by disconnecting it from the mains for a minute or so before reconnecting it again and carrying out a "first time installation", should this be offered on the set up menu, otherwise just use a normal auto-tune.
You should also try the "disconnecting from the mains" procedure on the BT box, although some of those boxes have issues, BT being the best people to give advice on this.
On 2 February there are changes to ITV reception for the Oxford and Ridge Hill transmitters | Freeview

Just to re-emphasis what Adrian Crafer said above, please note that the local channel from Oxford is on UHF channel 29 ( contrary to what is shown on this web page ).

John Dennington, perhaps your Humax is more sensitive than your Tvonics, so can work with a weaker signal.

Colin Flindell, have you tried a clean retune ?
To do this, unplug the aerial and do a full scan. Your channel list should then be empty. Then manually tune to each of the transmission frequencies ( channels ) listed on this page.
