The symbol shows the location of the Hannington (Hampshire, England) transmitter which serves 470,000 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 Hannington (Hampshire, England) mast?

Bob: The grey and strike-out are simply meant to indicate the services that close down. It doesn't mean it isn't happening.

Roy Hole: It looks like you're primarily a Crystal Palace viewer. If you retune on the Hannington dates, you should still get Crystal Palace services on the regular channel numbers. Your receiver should also store Hannington services on other channel numbers, but those numbers are not fixed in the specifications. I believe it's recommended that they are stored from 800 onwards, but some boxes just use the next number available after the first copy of all services have been stored (which will be around 312 or so), or fill gaps (there are gaps at 8, 35, 45, 47, 50-59 if you don't have HD, 53 and 55-59 if you do, etc) or use 1000 onwards. Some boxes don't store them at all.

Only the high-power BBC services from Hannington launch tomorrow morning. ITV1, C4 and C5 launch at high power on 22 February. The order you get may depend on whether you retune on both dates, or only after it completes. It's likely that ITV/C4/C5 channels from the South region would be stored before the BBC South set, as they will be on a lower frequency and therefore be found first.

Analogue television only carried a recommended channel number from the late 1990s, and again, there wasn't really a spec for where additional copies of the same channel should be stored, so different TVs may have behaved differently, or behaved differently in different parts of the country.

Is it you usually after the last programme on BBC 2 the switch off occurs ? I've got a snowy black and white picture here in Brghtton...

Is any annoumencent made before also ?

Kieran R: As has previously been explained, Hannington has a 'notch' in its low-power digital coverage, with seriously reduced power transmitted to the east. This may be the cause of your current problems, though you have previously mentioned trees between you and the transmitter.

The high-power digital services will eventually transmit from the new main antenna, which does not have this notch. The notch is designed to protect reception of analogue channels from Guildford, so it cannot be fully removed until the London region switchover in April. The power will be increased to the maximum permitted, and the modes will be changed on 22 February, as advertised, however.

BBC A (Mux 1): 8 February (retune tomorrow after 6am)
D3&4, BBC B (Mux 2, B): 22 February
ArqA (Mux C): 4 April
SDN, ArqB (Mux A, D): 18 April

If you don't get all the muxes after retuning on 22 February, you will need to retune on the April dates to get them.

Digital UK's predictor continues to predict a good service for you on all multiplexes; between 22 February and 18 April the commercial muxes are predicted to be worse than now, as the power increase doesn't offset the additional margin needed after the mode changes. After the restriction is removed, 99-100% of locations in your grid square are predicted to get near-error-free reception 99% of the time. That figure *is* calculated on the basis of a good quality, reasonably high-gain, fairly directional roof-top aerial, with reasonably short downlead, without too many obstructions.

You've previously used Crystal Palace. That should be a good option for the PSBs but is expected to be poor for the COMs, as they will use the same frequencies as Rowridge. You're in the zone where Rowridge is too weak to be usable but still too significant a source of interference. The model used in predictions isn't as directional as most aerials actually are, so it may be better than predicted.

Do be aware when retuning that many boxes store the first version of the channels that they find, and any Hannington viewer may find that Crystal Palace is stored first - particularly when retuning after April, when CP will be 10 times its current power level.
