So only 14w when Patcham can this be enough compared to 69w analogue where portable reception is not great with me at the moment

Will there be any testing before March 7th ??

Dave: Because they're not actually comparing like with like.

It's stated that analogue transmissions require 43 dB of signal-to-noise ratio - about 20,000 times the power from the signal compared to the interference - for perfect reception.

Simulations show that error-free digital reception only requires 17.3 dB signal-to-noise ratio - about 0.27% of the analogue difference. However, this is the absolute minimum required: any lower, and the picture and sound start to break up. The broadcasters' statistics show that, to provide reliable results, the signal needs to be about 12.8 dB higher. They've also added about 6 dB of fudge factor (i.e. nearly 4x power levels), making for 36 dB in all.

This 36 dB of signal-to-noise ratio is 7 dB less than the required analogue level, so in general, levels have been set 7 dB lower than the analogue levels, or one-fifth of analogue power. This is the same right across the country, except that the south-east coast transmitters have been set higher to provide extra resilience to signals from continental Europe, or perhaps reflecting better aerial systems that send relatively less signal overseas.

Experience seems to be showing that the 6 dB fudge factor is unnecessary and levels could have been set lower. In effect, the digital coverage areas are actually larger than the analogue ones.

Ok interesting and informative Mike thanks :). All made clear now !

Shows how wasteful analogue transmission is

Dave: As the transmitter will be using the old analogue channel allocations (C43, C46, C50) for Freeview, not testing is possible.

Oh right ok would be good to have another MUX on there even local community tv perhaps ?! PTV !

More HD channels would make more sense also

Dave: Ah, I think you misunderstand. The purpose of the DDR is to remove bandwidth from television services, for example for 4G mobile data services.

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.
