A Senate plan to spend $7.5 million for a television version of Radio Marti has run into heavy opposition from the National Assn. of Broadcasters, which fears a broadcast jamming retaliation from Fidel Castro’s Cuba. The NAB board of directors demanded Friday that Congress compensate any U.S. TV or radio stations that are affected by Cuban interference brought on by the transmission of Television Marti. NAB officials alleged that experimental broadcasts of Television Marti, aimed at Havana from a location off the Florida Keys, have already resulted in some jamming interference on U.S. commercial radio stations located in Gulf states. The NAB issued similar warnings when Radio Marti--a Cuban radio service of the Voice of America--began broadcasting into Cuba three years ago.
