Viewers in South Yorkshire and Chesterfield that use the Sheffield and Chesterfield full-service Freeview transmitters (and their relays) will have no analogue television from Wednesday 24th August 2011. Unless you use cable or satellite to watch television, if you don't use a Freeview box or set, your screen will be blank.
Most people need only perform a "full retune" on their Freeview box or TV, but it would be impossible with 157,800 homes covered by the transmitters, for no-one to have a problem. In particular the ArqB multiplexes at Sheffield and SDN, ArqA and ArqB multiplexes at Chesterfield will be at restricted power for several weeks after the "end" of switchover - see below.
From Wednesday 24th August 2011 you MUST have a digital television device to watch TV. If you do not have a digital receiver, from Wednesday will have a blank screen.
Do not expect a terrestrial television service from midnight until 6am - or a late as lunchtime on relay transmitters.
Switchover help scheme
If you are over 75, get (or could get) Disability Living Allowance, Attendance Allowance, Constant Attendance Allowance or mobility supplement; or have lived in a care home for six months or more; or are registered blind or partially sighted and need assistance, please see The Switchover Help Scheme.
Cable and satellite
Cable (Virgin Media) and satellite (Sky, Freesat, fSfS) viewers are not affected by the changes. Remember, however, that you may be using analogue TV to watch on a second or third set and it might need a Freeview box.
If you scanned during the first phase of switchover on Wednesday 10th August 2011 - you will have to do it again on Wednesday 24th August 2011.
Restrictions on SDN, Arqiva A and Arqiva B multiplexes at Sheffield an Chesterfield
At Sheffield, the ArqB multiplex will operate on C63 on 24th August 2011, and will move to the final position, C49, and power level on 28th September 2011, when C49 stops being used for Channel 5 analogue on the Oxfordtransmitter.
At Chesterfield, SDN ArqA and ArqB are restricted to only 40W output until 12th October 2011 when it becomes 400W.
If you live close to the transmitter, you may have to disconnect any "boosters" from your aerial system. The new, more powerful digital signals may overload any amplifiers and result in no reception! When looking for them include a check for distribution amplifiers, loft boxes, set back amplifiers, bypass Amplifiers, hidden masthead amps in a loft space and any dodgy active splitters.
Homes without Freeview now have Freeview Light
If you had no Freeview service before, you will have the BBC channels digitally from Wednesday 10th August 2011. This is a single multiplex of the BBC channels (radio, television and text) for most people.
However, if you were on the fringes of reception from one of the main Freeview transmitters, you will now get all the Freeview channels.
If you didn't get this limited Freeview service on 10th August 2011 then you may need a new aerial.
Everyone who has digital-only terrestrial TV now has the ability to receive Freeview HD, see below.
Digital regional overlap
The old analogue TV signals provided lots of nations and regions for the public service channels, and these have large areas of overlap.
The old low power digital TV signals were at very low levels and reception of signals from more than one transmitter was a rare event.
All Freeview boxes automatically scan the available broadcast frequencies looking for channels, and they do this from C21 to C69. Older Freeview boxes will, if a duplicate version of a channel is found whilst scanning, such as another BBC Oneregion, placed it in the 800-899 channel range.
Some of the latest Freeview boxes will pick the strongest signals for the "primary" number positions, and some will detect the different regions providing a choice when you perform a "scan for channels".
The 800-899 is easy to access by pressing CH- from 1, and in most programme guides is just a single scroll up.
Freeview HD will start on Wednesday 24th August 2011 from Sheffield, Chesterfield and all the relay transmitters. You will need a Freeview HD - DVB-T2 receiver to watch the channels. An HD TV set with Freeview is not enough.
Hello, have lost all bbc freeviewchannels in the last half hour. Tried retuning (4 times), checked all connections and aerial, etc, still no bbc. ITV ok.
Anyone else got this problem? I am in the Crookes area of Sheffield .
