Ofcom is testing the new digital radio standard DAB+ in central Brighton, West Sussex.
The service, appears to be two DAB+ channels from Sussex Heights (a residential tower block) with a loop of announcements on each one titled BEX6 and BEX7.
The on-air announcement says: “This is Brighton Experimental; a transmission licensed by the Office of Communications for the testing of new developments in digital radio technology. For any enquires about this transmission, please call 0207 783 4021"
