Switchover starts in Berkshire and North Hampshire

If you live in the Hannington transmitter area your digital switchover starts this week, with two weeks before analogue stops forever and high power digital replaces it.

published on UK Free TV

This week sees the first stage of the digital television switchover for 483,600 homes in Berkshire and North Hampshire.

From 6am Wednesday 8th February 2012, you must perform a "first time installation" retune (sometimes "Factory Reset" or "Shipping Condition") on your Freeview box or television set if you use the Hannington full service Freeview transmitter.

This is because the old low power "multiplex 1" BBC service (on C50) will be replaced by the high power BBCA multiplex on the old analogue BBC TWO frequency, C45.

On Wednesday 8th February 2012 if you use the Aldbourne (6am), Alton (9am), Chisbury (6am), Hemdean (9am), Hurstbourne Tarrant (6am), Lambourn (12:30pm), The Bournes (noon), Tidworth (9am) relay transmitters you will be able to receive the BBC Freeview services (with the exception of HD) for the first time, and you will no longer be able to view BBC TWO on analogue.

Hannington (and relay transmitters)

You MAY find that old equipment will no longer work - see TVs and boxes that do not support the 8k-mode

Another common problem at switchover is the increase in signal from 10/20kW to 50kW will overload amplifiers and over-the-top aerial installations. If this is the case you will have to remove the booster or amplifier from the system, or perhaps fit an attenuator if you have no amplification. - see Freeview signals: too much of a good thing is bad for you.

Winchester

On Wednesday 22nd February 2012 will see the second stage of switchover, which provides the final Freeview configuration, including Freeview HD for all transmitters in this region.

On this date, you will need, once again, to do a "first time installation" as indicated above.

If you are over 75, you should already have been supplied new equipment by the Switchover Help Scheme.

Briantist: That'll be too much signal caused by having too big an aerial. The Guildford Notch caused digital signals to the east to be cut by up to 22 dB. That means viewers due east have an effective 26 dB, near 400x, power increase between Mux 1 and BBC A.

Hannington's pre-switchover radiation pattern can be found on p8 of http://downloads.bbc.co.u….pdf (red line). The 'proposed' blue line was never implemented - I believe it reflects the old triangular cross-section antenna (when looking from on top). The new main antenna has a pentagonal cross-section, it has five faces, so will be somewhat different from that.

Briantist: Sorry, just seen the spectrum analyzer photo that someone else posted, indicating actual low signal.

However, once the power does reach the full output, my point still stands: many people to the east of the transmitter may have had too large an aerial and/or amplification fitted to try to pick up the very, very weak signals that were all that were available. Too much signal on analogue manifests itself as noticeable, but not too annoying, patterning. A digital signal is wrecked.

Mike Dimmick: I did post a link about the too strong signal issue at the top of the page.

However, Arqiva have confirmed there is an ongoing fault condition at the moment.

It seems the signal problem has possibly been corrected as the second image shows.

C/N: 24dB

Signal Strength: 95%

Quality: 100%

Has booted out BBC1 London from LCN1 on an autorescan.

Now the problems begin...

mr g bull: You are expected to get your digital signals from the Crystal Palace transmitter, so you should be getting BBC and ITV London.

You will also get a poor digital service from either Hannington (BBC South) or Oxford (BBC Oxford).

If you can get other versions of BBC One/ITV 1 channels, they will be in the 800-899 range.
