The industry are determined to ram this change through, and I understand they will try to do so when 50% of households have a DAB radio. Let us just hope that is a very long time coming. And since they are aiming for 50% it s hardly surprising that they will continue to pump out propaganda and fictitious statistics. Jonjel, Talking about having things rammed down one's throat, I felt the same thing yesterday when I tried to thread a needle and sew (not my usual pastime) under the glow of an energy-saving light. It is supposedly the equivalent of 100 watts(=2000 candela), but I suspect they meant 100 candela! The net result was that I had to put on an additional two table lamps to get sufficient light. So much for energy saving! From where I stand, it was another knee jerk reaction to energy saving that will soon be superseded. I wonder if DAB will go the same way. |

Strange as it may seem I have trouble with needle threading these days, so much so that I have bought some of those little wire jobbies to help.
I thought it was failing eyesight, but you are proably right.

I have measured the power consumption of a few DAB/FM radios by connecting a power unit with digital readout of Volts and Milliamps to the battery terminals.
An older set does indeed use about 3 times the power on DAB but more modern ones only use slightly more on DAB and one a Pure 1500 personal set uses twice as much on FM as DAB.
Modern FM sets with digital readout, stereo (headphones), stepped tuning and maybe RDS use a lot more than simple analogue dial sets. So use a simple cheap FM set in the kitchen if you have to run on batteries.
In household terms the power consumption of any radio is pretty tiny and will be less than + or - accuarcy and temperature stability of your electricity meter.
Droitwich 198 uses more energy than millions of DAB sets used for several hours a day.
The energy needs per radio station on DAB will be a fraction of that of FM.
There will be considerable energy and therefore money savings by moving to digital TV. Analogue TV transmitters are very inefficient. About 85% of the electricity boils water. Steam TV indeed.
