As weekend fans of WLRN-FM (91.3)'s venerable Sounds of the Caribbean show know, all is not copacetic in the world of Miami reggae radio. In fact there is no reggae radio as fascinating as the show put on by DJ Ital-K since his program was terminated in October. Kevin "Ital-K" Smith might not be spinning reggae nuggets on air, but he is waging war with the public radio station, which is run under the auspices of Miami-Dade Public Schools. Smith's fight, made even more rancorous after he filed a complaint with the Equal Employment Opportunity Commission charging WLRN with racial discrimination, is entertainment enough. Who would have thought that such a sweet program could lead to such bitterness? To hear the best in reggae warfare, tune in to the monthly broadcasts of the Miami-Dade School Board meeting on LRN. Smith, technically a suspended employee of the school district, has come before the board at least four times asking for an explanation as to why he was yanked from the radio. He has yet to get an answer, and his repeated requests for meetings have been dismissed, promising more great debate shows as he continues his struggle. It's hoped his old show will be returned and everyone can get back to the island grooves. Meanwhile, though, the hottest sounds in reggae come from the bickering and battling between a DJ and an institution.
