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?

Dave Lindsay:

It's an Antiference HDSB (based on a Vestel T8300), a quick Google search turned up a document that indicates that the software version I am using only supports one HD MUX. The good news is that there is an update that should support multiple ones. I just have to get the courage to update the box. Will let you know how I get on just in case anybody else has this box or equivalent.

Is the new That's Oxford programme - broadcast via the Oxford transmitter - purely broadcast to Oxford city itself or is it intended for the whole area reached by the Oxford transmitter? I live in Faringdon and would love to be able to see this as we get very little Oxford news really - the "local" news aimed at us is mostly about Basingstoke / Portsmouth and even Sussex, with only about 10 minutes Oxford news out of half an hour at 6.30 pm (BBC).

Tig Minor: There are a few points to make in answer to your question.

Firstly, That's Oxford broadcasts directionally from the Oxford transmitting station and in the direction of Oxford. It is also on lower power (4kW) and is on a UHF channel out of group of former analogue.

So, you are in the direction of the beam. However, there is higher ground in the way which may cause difficulty:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location


The possibility of "out-of-group" means that the broadcast frequency is out of the band of frequencies that your aerial (if it's C/D) works best at. And not only may your aerial be less sensitive, the signal is weaker.

See here for an explanation of aerial groups:

Aerials, TV Aerial and Digital Aerial

Analogue TV from Oxford was all in Group C/D. That's Oxford is on UHF channel 29, which is Group A. Also, COM7 (and the forthcoming COM8) HD muxes are on Group A channels. So you "may" require an aerial replacement to pick them up as well.

Try going to the manual tuning function of one of your TVs/boxes and select UHF channel 29 but don't press the button to scan/add services. Rather wait and observe for a minute or so how the strength and quality fares. Some receivers are more useful than others at this so it's worth visiting them all.

Tig Minor: I should add that overall your chances of reliable stable reception aren't great! But if you find that reception of COM7 isn't great then you might decide to replace the aerial for a wideband, and at the same time you might be able to bring in reception of That's Oxford on C29.

Dave Lindsay - Many thanks for your comments. Being something of a technophobe, I will have to think about it!! In general, reception is great at present, but I note your comments that chances of reliable stable reception for That's Oxford - presuming I can get it - are not great. Might be safer top let well alone for the present with my current aerial, but maybe a change to wideband in the future is an option.

Many thanks..

Here near Swindon I changed from a C/D to a wideband aerial and That'd Oxford test transmission is quite strong considering the low power. Quality is good and no drops out even in different weather conditions.

ITV programme guide has from 6.00 am today been displaying instead of the programme details "this channel is moving". I assume this is an error considering the status of ITV, so is one of the ITV group moving?

Adrian Crafer: There are changes due today for ITV regions. Will vary on exactly where you are and what box/tv you have, but looks like a retune needed to get the epg data.
