The Southampton small-scale DAB multiplex launched in August 2024 under Southampton Digital Radio Limited to provide a digital broadcasting platform for local, community and specialist radio stations across Southampton and surrounding areas. When it launched, the service relied on two transmitter sites: Millbrook Tower and Dumbleton Tower. However, Ofcom's consultation documents reveal Southampton DAB can no longer use Millbrook Tower after changes linked to new fire risk legislation. As a result, the Millbrook transmitter, which provided the majority of the multiplex's coverage, has been off air since May. To replace the lost site, Southampton DAB has proposed installing a new transmitter at Romsey Golf Club, about 2.7km north of Millbrook Tower.
