Andy: my understanding is that the work over the last few weeks was moving *analogue* transmissions from the reserve aerial back to the new main aerial. There might have been occasional periods of reduced digital power if men were working on the mast.
Hannington has never transmitted digital signals to the east: the whole sector from south-east to north-east is omitted because they would interfere with the analogue signals from the Guildford transmitter. Protecting analogue transmissions was the priority when the low-power digital signals were added.
The new main aerial is omnidirectional (to the best of our knowledge - it has to provide much the same coverage area for analogue as the old one did) and will provide high-power digital service starting in February 2012.
If you've had a reduction in performance over the last few weeks, the most likely culprit is that signals from distant interferers have been travelling further due to the weather conditions. As far as the broadcasters are concerned, though, you're out of coverage (at least from Hannington). Signals should be less susceptible to these weather conditions after switchover.

Evening still bad reception. Until last week got 60+ channels including itv etc but now down to about 10:( clearly a problem with the area.

I am confused.
Brian says that there is no work ongoing at Hannington, but Mike refers to work on the analogue ariel.
We are also told that Hannington is not broadcasting a digital signal, but the whole of this discussion thread is on a page headed "Freeview on the Hannington transmitter"...
I have been living in Basingstoke for years and have had good freeview reception from the day I first got a freeview box. I have always been told that the signals are coming from Hannington... that was always proved to me by the fact that most people on the west side of basingstoke would get itv meridian and bbc south-west, but those on the London-facing side would get itv and BBC London... even on freeview.
I just don't understand why the digital reception could be fine for so long, and then suddenly drop so dramatically. Weather seems like a "leaves on the line" excuse - sorry, no disrespect intended!
Oh well. Since I'm not supposed to be able to watch freeview (along with all the inhabitants of Basingstoke), I guess I'll just have to put up with it until 2012. Sorry for sounding frustrated.

Evening. Have spoken to several neighbours, who have all lost itv1,2, channel 4 5 etc seems to be multiplex 2 is gone and low on many others. Happened a week or so ago so assume as Brian has said maybe weather. Seems to have effected big area ie Basingstoke, fleet etc. Roll on 2012;)

Andy: Weather conditions can cause transmissions to travel further than expected. The fact that a number of transmitters in the north and west of the country have already switched over means that there is now something to interfere with the transmissions, where there wasn't before. (Other digital transmissions on the same channel seem to cause more problems than analogue transmissions on the same channel.)
In addition, sites on the continent are now broadcasting digital only in the UHF band, where many analogue channels used to be broadcast at lower frequencies. It all adds up to a noisier environment than a few years ago.
On top of that, there may be periods where power has to be reduced slightly, if men are working on the mast, though this should only happen during daylight.
The 'analogue' aerial has pride of place at the top of the mast, has plenty of gain, and is able to handle plenty of power. The 'digital' transmission panels are bolted to the west side of the mast, and point due west, slightly west of north, and slightly west of south. To get the full coverage and power levels, digital signals move to the main aerial at switchover - this is why the transmitters are off-air for about six hours on the switchover days!
Just as your receiving aerial isn't really 'analogue' or 'digital', nor are the transmitting aerials. They're tuned to work best in one area of the UHF frequency band (for Hannington, between channel 35 and 68), but otherwise it just broadcasts whatever is fed to it.
The old 'analogue' aerial was erected in 1969 and had reached the end of its useful life at 41 years. Technology has moved on and the new designs can direct more power to ground level rather than up in the air. So a 'reserve' aerial was added in July 2010 to handle analogue transmissions temporarily, and the old main aerial replaced in October. However, I don't think there was time before the weather turned to get all the cables replaced and the new main aerial into service. That's what I think they've been doing over the last few weeks.
As for 'dropping dramatically' - digital requires a certain amount of signal quality to work, but above that level, you get no improvement. We call the amount of signal you have above this minimum level the 'headroom'. Deterioration in equipment and increases in noise reduce this 'headroom', but you won't notice a thing. Then it drops below the minimum required level, it starts to block and break up, and rapidly just goes to NO SIGNAL. Most digital boxes do not measure the headroom - their signal quality meters only report *uncorrectable* errors. This makes them completely useless.

My post code is GU14 7AZ, which is a block of 26 flats. The building has a common coax system fed by an aerial pointed at the Hannington transmitter; seemingly this has been chosen by most buildings nearby because of the topography. Because of the unacceptable Freeview reception using the aerial system, half of the flats have paid to have a Freesat system set up.
Q1. Are we on the correct transmitter?
Q2. When Hannington goes fully digital/Freeview, should we be able to ditch Freesat with its cable rental costs and get the full Freeview set of signals?

Just to confirm, here in Reading (specifically Caversham) we now have poor reception on ITV1/C4 etc., and have done so since early March. So clearly something has degraded the service from Hannington.
BBC channels are all still fine.
I'm not really sure about the comments regards Hannington only transmitting digital signals to the west, both the Freeview website and this one all state that in our location, Hannington is our digital TV transmitter.

Derek Twigg: The Digital UK postcode checker does not currently show any results for reception from Hannington, but after switchover predicts good reception using this transmitter on all six muxes for your area. At present Crystal Palace is shown as offering variable to poor reception for Freeview, after switchover this becomes good reception on the PSB muxes and variable reception on the COM muxes.
