It is a big night for fourth former Scarlett Leung Tik-ka. The 15-year-old goes on air, presenting a radio show for the first time on local station HMV864. 'Hi, everybody, this is Scarlett Leung, and welcome to the Scarlett Party show. Coming up is Eternity by Robbie Williams. Stay tuned.' Immediately afterwards, she receives phone calls from listeners rooting for her. 'I have always wanted to be a DJ, because I just so enjoy talking to different people. I couldn't be happier if I had my own show in the future,' she says. The St Mary's Canossian College student joined a DJ training programme run by the radio station this summer. The reality of presenting a radio programme is 'a far cry' from what Tik-ka had imagined. It entails a lot more work than she thought. Tik-ka arrives at the studio an hour in advance. The first thing she has to do is go through the programme's schedule. 'It is crucial that you run your show on time. If your show overruns, it will upset the entire schedule for the rest of the night. And all the commercials will have to be delayed,' she says. 'The trouble is, since we are buying airtime from the channel for our show, every extra minute will cost extra money, she explains. Every song she plays and every phone call she takes must fit into the schedule. Between songs, she has to take phone calls from listeners, which requires special skills. There are always some callers who are too eager to talk. It is the most common problem for phone-in shows, she says. Sometimes the DJ has to stop them. 'You do have to interrupt them sometimes. It is part of the skills a DJ must master,' Tik-ka says. 'You have to do it politely, because you don't want to upset your listeners, but you don't want to upset your schedule either.' When it comes to preparing a recorded segment, there is also a lot to learn. The segment has to be organised depending on whether it is a conversation or an interview. Audio effects have to be created, then it has to be edited to fit the schedule. It takes dedication and hard work to be a good DJ, the training programme's organiser says. HMV864 production manager Alyson Han Ka-ming says: 'It is wrong to think a DJ only needs to be articulate and humorous.' Tik-ka, an aspiring musician, says after her radio debut, she has started to consider the possibility of becoming a DJ. 'The two roles are related. As a DJ, you must know about music. I believe I have an edge over others because I have real experience in both [areas],' she says. Tik-ka says she prefers radio to other media because on the one hand, she enjoys taking calls, and on the other, she feels inhibited in front of cameras.
