Can I Still Listen To The Analog AM And FM Stations I’M Used To?

Of course can. You can still use AM and FM analog radio services. Despite the introduction of digital radio DAB, the analog radio service has not been "closed". This is to promote digital radio broadcasting.

You can continue to listen to your current favorite analog station using the radio you currently have. You don't need to buy a new radio. The DAB+ receiver has a new digital-only DAB radio service. If you want to listen, then you need one.
