The Miami area once had several renegade stations that eschewed advertising, including The Womb (107.1 FM) and SupaRadio (104.7 FM). But a federal assault on unlicensed broadcasters squelched them and many other pirates in 1998. In the secretive underworld of pirate radio, where stations are here today and shut down by the Federal Communications Commission tomorrow, it's hard to discern just what is going on. But our antenna detects a trend, albeit nascent, toward purist piracy. We especially like the nighttime spinning on 101.9 FM, because the DJs on this frequency seem to be more interested in airing their beloved Haitian compas than getting people to show up at someone's dance party for ten bucks a head. Okay, once in a while the Kreyol-speaking announcers might plug an event or store, but they do so far less than our allegedly commercial-free public radio station, WLRN-FM (91.3), which runs full-fledged ads disguised as corporate underwriting. We've also witnessed such low-key pirates on 94.5 FM, where they let the hip-hop speak for itself without interruption, sometimes for hours at a time. It is our humble hope that other unlicensed broadcasters will stop squandering the chance to create a true alternative to the oppressive and unimpressive state of commercial radio in South Florida.
