Setting up a radio station for FM or AM broadcasts in Hong Kong is neither easy, nor cheap. Metro Broadcast operates two FM channels and one AM channel, which must have 80 per cent of its programming in English. It also forks out more than $3 million in annual licensing fees. Recently, its licence was renewed for 12 years, with a mid-term review to be conducted by regulators. As part of Metro's licensing requirements, the broadcaster said it would upgrade old equipment to improve reception and reduce the number of blind spots, in particular at Cyberport, Sha Tin and in the tunnel areas. More programming content would also be devoted to education, culture and young people. The review is designed to keep tabs on programming and investment commitments made as part of the licensing agreement, and to evaluate complaints.
