The message
from "Dave Plowman (News)" contains these words:

Digital transmissions are on the same frequency throughout the country.
Unlike analogue where this would cause problems with cancellation etc it's
actually a benefit because in weak signal areas the two add.

And for all the power the BBC and Castlewotnot will be saving when the
cut the ERP of the transmitters, the rest of us will be paying in
mains/battery electricty to run the DAB receivers which use a lot more
juice than analogue radios.
