2SER, 107.3 FM. A university/community radio station with no agenda except to provide Sydney with an excellent underground radio alternative. Answerable to the University of Technology, Sydney, and Macquarie University, it's staffed mainly by volunteers and funded by listeners' donations. In return for becoming a financial supporter, listeners can win all kinds of free stuff and get discounts at certain stores--as well as have the satisfaction of knowing you're supporting a broadcaster that's uncontaminated by political pressure, record label influence or playlists.

It plays music you'd probably not hear anywhere else, and the range is huge. Individual shows are dedicated to Japanese pop, experimental noise, electronica, 60s soul, 70s punk, indie, metal, and more; and every weekday, noon-4 p.m. (as well as on certain nights), the whole spectrum of dance music (for want of a better term) is covered. Plus news, current affairs, science, literature, foreign language community broadcasts. Almost everything you'd ever want your ears to hear. Its website is www.2ser.com.
