BARRY-
what is your postcode and do you know if your existing aerial is running through an amplifier or splitter?

We are at BH13 7NH (Canford Cliffs), and receive our Freeview signal from Rowridge. We have a modern digital aerial professionally installed about 3 years ago. We have not needed to adjust it during or after the change over procedure.
However in the last week (approx since 19 July 2012) we have started to have problems receiving Sky News (82). It often breaks up and is sometimes no longer found when we do a retune.
So we have looked at signal quality for each of the 100+ channels using the facility on our Panasonic TX-P42G20B TV. We find that signal quality is perfectly fine (100%) for all channels except for the following 20 which are all about 30% - 40% quality level:
11
19
20
25
29
36
37
43
46
49
62
82
87
90
84
96
97
98
108
193
Do you suggest we have the aerial realigned towards the Poole transmitter, or is there a simpler method?

Hi, your poor signal seems to be on the commercial muxes.
The best thing to try first is to have the aerial tilted so that the elements are vertical as apposed to horizontal.
The reason for this is that they signal strength is stronger on VP setting rather than on HP setting.
The fact that all has been fine up until recently could also indicate that maybe something is being built in your signal path, causing your weak signal.
I would try altering the aerial first then go from there.

Trevor Rhodes: Short answer: Have your aerial changed from horizontal to vertical.
Long answer: The Poole relay does not carry the Commercial (COM) multiplexes; only the Public Service Broadcaster (PSB) ones, so you would be worse off. Indeed, it is COM5 you are having issues with, and you may be susceptible to poor reception of COM4 and COM6 as well due to the clash with Stockland Hill.
For services and which multiplex they are carried on, see:
DTG :: DTT Services by Multiplex
After switchover, digital signals from Rowridge are broadcast horizontally and vertically. The horizontal signals are there there for compatibility with existing aerials.
The PSBs (BBC, ITV1, ITV2, C4 etc) are at a power of 200kW horizontally and vertically, whereas the COMs are 50kW horizontally and 200kW vertically. The COMs are lower power horizontally because the three channels (frequencies) so that they can be used by other transmitters (in closer proximity than what the PSBs' channels are re-used).
In your case, you could be suffering from interference from Stockland Hill as its COMs use the same three channels. It is horizontally polarised only, so changing your aerial to vertical polarisation should help "rejection" of the unwanted signals.

M Brown: Should this just have been fitted (as you haven't mentioned) then have you ensured that the aerial is mounted vertically and is facing 296 degrees if receiving from Poole @ 1 mile or alternatively 97 degrees if its Rowridge @ 25 miles, as indications are that you should be able to have good reception from both stations.

Has anyone else experienced free view reception issues today? We have no problems at all with signal normally but today we have experienced a lot of interference. The picture is periodically blocky with a delay much like if you experience bad weather when using a sky signal.
Someone else suggested it could be related to air pressure, is this likely?

I lost all Freeview channels last night towards 23:00hrs but they are back this morning. I have a new aerial vertically aligned at Rowirdge. Did the transmitter fail??
We had excellent analogue reception in Selsey before we opted for a Freeview DVB TV set and the new aerial, but have experienced digital reception problems ever since.
If this is progress they can keep it!! We pay our licence fee in advance and expect good reception every day.

many things can cause problems with reception.
The key questions are:
is your aerial good
are the cables and connections good
do you have any splitters or amplifier
what area do you live in
are there specific channels that are not working
With all systems there can be problems from time to time
however all equipment can have a life span of about 20 years.
Just to confirm that Rowridge transmission has been perfect the last few days.
If you provide your location and system details I may be able to provide more information.
regards
Jamie
