The symbol shows the location of the Tacolneston (Norfolk, England) transmitter which serves 330,000 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 Tacolneston (Norfolk, England) mast?

No, it is NOT the equipment: everyone suffers the same problems and we can measure signal strength.

This winter, as others have said, signal strength has been so low as to render most TV unwatchable. This isn't restricted to a single user, it's many and all over the xmitter area.

I'll accept (just!) atmospherics but not my equipment which is beyond reproach.

Re my last - analog signal strength has been fine all along, it's only digital that is affected.

Sorry to bang on but rereading this page it is clear that Freeview transmission strength will reduce from 100,000w to 75,000.

Am I missing something here?

If not, this means that far more people will be unable to receive Freeview than pre DSO.

Or, was the 250,000w previously seen correct?

BTW, your reply to Anne may be the obvious but I, too, have had Meridian appear instead of Anglia - and no satellite receiver here. I put it down to digit problems of the finger kind!

More.

I've been using your excellent reception map and it clearly shows a large reduction in signal strength post DSO.

Is this really going to happen? Thousands will have no TV reception at all.

Richard Baguley: Yes, you have missed quite a lot.

The analogue services are 250kW, Freeview is currently 10kW and 5kW.

After switchover Freeview will be 100kW.

Remember that less power is required to provide the same coverage for digital.

Everyone who has analogue before switchover has digital afterwards.

Last one today - sorry!

I did reread and found your quote (amazing how sometimes, no matter how many times you can read something & never spot what you're looking for!):- "Freeview power increases from 6,667W (average) to 100,000W, 14 times stronger."

This sounds like good news but your signal strength map shows a reduction in power as does your statement that power will go from 100,000 to 75,000.

Confusing.

Clarification of which statement is true in terms of perceived signal strength (i.e. susceptability to gligital ditches) would be very helpul given the difficulty, these days, of contacting BBC Engineering.

TIA

Richard Baguley: OK, this is because the value takes into account the NEW7 and NEW8 allocations, which have no power value and are pulling the average down.

I'll have to recode it to ignore the zero values.

Richard Baguley: Basically

100,000W x 6 / 8 = 75,000W.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
