Matt: I wonder if it is interference from another transmitter that uses the same three channels (41, 44 and 47). Hemel Hempstead uses those channels and it switched last month (although its signals are vertical as opposed to Hannington's which are horizontal so that should help rejection to a degree).

Matt.
Given your location , is there any particular reason why you want/need to receive from Hannington rather than Oxford? In theory Oxford should be a better bet - but maybe you may have some local obstruction to the north (building, tall trees etc) (for Oxford) whereas it may be clear to the south (for Hannington).
What sort of aerial are using (group B, C/D or wideband) and what direction is it pointing?

Hi, Apologies for late reply. Dave Lindsays suggestion sounds plausible. RichardS is also right about Oxford being closer but it is blocked by Wittenham Clumps and some trees, and gave poor reception when the aerial was first installed pointing towards it, particularly in windy weather. During the first stage of the switch I did get quite a good signal from Oxford eventhough the aerial was pointing in the opposite direction ( slightly east of due south) towards Hannington. Although much further away the ground slopes away to south and so no local obstructions in that direction.
I'll check the aerial tomorrow and send an update. It's possible I suppose that it's group C/D (for Oxford) and should be a group B (for Hannignton ) but as I say, it all worked fine before the switchover.

Hi
Following up on my previous post. I have a wideband aerial with an upmast amp. It looks pretty much like this

Any help on my poor reception probs much appreciated

I could really do with some advice. Postcode is GU14 9RX, trying to get a picture from Hannington specifically for BBC South East.
Wideband aerial on 3m pole on chimney, with masthead amp, and then 2 way distribution amp.
My brand new TV upstairs gets a lovely picture all the time, yet my older TV downstairs fluctuates daily.
I've tried removing the dist amp, but a direct connection to the masthead has no effect. The upstairs TV works fine downstairs, which leads me to think it's TV rather than aerial related.
Are the tuners in the latest TV's significantly better? Is there anything else I can try? Banded aerial or 2 way masthead for individual feeds?
Thank you.

Jon: Although I feel that your problem is likely to be caused by the older TV having a less sensitive tuner or is suffering from an incompatibility problem with the new transmission modes being used, but you should really have completed your test by trying it upstairs, if at all possible that is! as I appreciate that some older sets can be extremely heavy.
Regarding the individual feeds, its always better for each aerial point to have an individual feed, as its the only way of guaranteeing that each device receives exactly the same level of signal.
Maybe you could indicate the model number of the TV in question, although its not necessarily the case that all older sets automatically have inferior tuners, as other factors can be involved.
By the way your area isn't exactly a stranger for complaints about reception, and I notice that you are not really predicted to receive the commercial channels at other than with a variable status, this being on a permanent basis.

JB,
Thanks for the reply. The TV is a Samsung LE32R41BD.
I knew that Hannington was problematic, but was hoping that the increased power post-DSO, and better coverage pattern to the east would give Farnborough a fighting chance.

Jon: It may be worth pointing out that before switchover, Hannington didn't throw out the same level of signal all the way around. In your general direction it was lower so as to protect against interfering with those receiving from Guildford as it used the same channels up to its switchover last month.
Consequently, the much greater marked difference in pre-switchover and post-switchover signal strengths on your side of the transmitter. This could mean that where an aerial system was installed to pick up the pre-switchover signals, it is now too sensitive for the post-switchover signals and is therefore providing too much signal to tuners that are connected.

Thanks Dave,
I've tried turning the gain right down on the masthead, and fitting a variable attenuator, with no luck.
Using the signal indicator on the TV (which I appreciate isn't accurate) shows max signal at mid-gain on the masthead amp, showing 40%. Turning the gain up further or down lower results in a lower signal indication.
It looks like the TV is very sensitive to signal quality, so I might try a grouped aerial, with a 2 way masthead so I can remove the distribution amp as a source of noise.
Unless there are any other ideas from the experts!

Jon: The reason for me requesting the model number of TV involved was to enable me to check on any possible service note additions that might have been made about it as most brands have them, however as it transpires that model is known for not having a particularly good tuner (if any Samsung does!) and which requires a signal strength in excess of 80% for satisfactory operation without it suffering from frequent glitches in reception.
Regarding the 40% level you mentioned, is that on the Samsung and is it referring to the strength or quality? as if its the strength then there is no way that the Samsung will give satisfactory reception at that level,(as aforementioned) and so I would be interested to know what the readings are indicated as being on your newer TV as well as the model of.
By the way some of the best types of tuners around for sensitivity and stability are fitted in Panasonic TV's, or in the case of a box or PVR, Humax leads the way.
