Dennis West: do a scan with the aerial unplugged and when it finds nothing so a full scan again.

Dennis West: As stated to you above, and to others, if you are using a communal aerial system, it may require adjustment. For this you will have to get in touch with the party responsible.

Your postcode resolves to a large block of flats which suggests that you may not be using your own aerial.

jb38: Reporting back after 29th as requested! Have only just retuned as have been away. All channels seem fine, and I appear to have all channels that I should have, both upstairs and down.

I live in apartment of 62 others with common aerial. Cannot receive Ch20 ITV3, can receive Chs1-9 & 11-20 all O.K.
TV eng informs me that this is the same all over Brackley. What can be done and what is the reason for this fault.

You need to do a manual return to UHF channel 50 or a full retune.
This is true for anyone using the Oxford transmitter. Brackley is no different from anywhere else.

Small Dog: Thanks for your update on the situation and pleased to hear that all is OK after the retune, however I do have to say that the improvement in reception from the hitherto problems mentioned could simply be down to the result of the rapidly occurring seasonal changes that have taken place over the last few weeks, as the effect of is always experienced to a greater degree where a person is located in a non line-of-sight situation such as applies in your case and where reception is always via an element of signal diffraction, (bending etc) as the direct signal path from Oxford is according to the terrain checker being obstructed from approximately 4 miles out from you, this of course is only referring to the land and excluding the effects such as from trees on the land, these adding to the problem

However, your aerial as far as its response to the lower channels is concerned would appear to be OK, although the SDN signal should be fractionally better by the fact of it having moved downwards in frequency, as lower frequencies are always better at getting over obstructions caused by such as trees etc, because other than that aspect nothing else has really changed with any of the other channels.

By the way, what I mentioned about seasonal changes being a factor connected with your reception problems is down to the fact that of your postings having been centred around the months of the year where the main changes are liable to be experienced, e.g: May 2010 / September - October 2011 / March to May 2012 / and of course May 2013.

Why does "Which BBC and ITV regional news can I watch from the Oxford transmitter?" above state that Oxford transmits Central news?
