Have you checked the frequency of that Station?
Also check your aerial.
I have also found this:
Listeners to DAB digital radio in the Merseyside area will need to retune on Wednesday 20th April following a frequency change that will affect local radio stations.
The local DAB multiplex carrying BBC Merseyside, Radio City 1-3 and Capital Liverpool among others will be moving to a new frequency in order to allow better reception over a wider area. The current frequency will be turned off late on Tuesday 19th April. The new frequency will go live from 6am on Wednesday 20th April, after which listeners will need to rescan their DAB radios in order to continue listening.
