Why do portable DAB radios gobble up batteries like there's no tomorrow? This latest technology seems a backward step when the old analogue manually tuned am/fm radios seemed to run for months on the same set of batteries.

Buy a charger and use rechargeable batteries. You'll save a whole lot.

Thanks for that "society" but WHY do they use SO much more power?
I don't know the answer to your question. But, I been using the same rechargeable batteries for the last five years and they are still going strong.
DAB uses much more power because the received digital signal needs much more processing to get back to the original audio than is the case with analogue signals.
