DAB is a long way off!
Surveys of radio listening show a low take-up of DAB radios.
At present rate it will be 10 years+ before there is any sign of substantial use of DAB.
Reasons are a combination of cost of the radios and signal issues.
Not enough car manufacturers are fitting them yet, and when they do it will increase digital listening,but by how much?
AM/FM appear to be safe for a few years yet.
