The station will become part of the new line-up of services on the new Digital 2 / Sound Digital multiplex, which is due to go live at the end of February.
Until 4th April 2016, the station will be simulcast on both its existing Digital 1 slot and its new Sound Digital slot.
In a multiplex variation request to Ofcom, Digital 1 said that Premier's owners had "been keen for the station to continue to broadcast on both multiplexes for a short period to assist its listeners make the transition to the second national multiplex", confirming that the the simulcast will end on 4th April.
With the new Sound Digital slot due to reach fewer listeners, because of its smaller coverage area, it's also been confirmed that Premier's owners are implementing a "communications strategy", which will help affected listeners "migrate their listening to other digital platforms with broader geographical reach than Sound Digital." The station is, for example, available to around 90% of the UK population on Freeview channel 725.
- In other DAB news, it's been confirmed that Heart Extra will have a mono slot on Digital 1, with 80kbps of bandwidth allocated to it. In many parts of the UK, the main Heart station will continue to be available in stereo via DAB.
