Mr. Liberman and Mr. Kramer, who just bought radio stations, have been duly found by the Federal Communications Commission to be Hispanics. That means the sellers of those two radio stations get a nice tax break because they have contributed mightily to the FCC's policy of encouraging "significant minority interest" in broadcast holdings.

Adolfo Liberman's family owns K-Love Radio Broadcasting Inc., which bought KNTQ in Los Angeles from Storer Broadcasting. Liberman, born in Polan, descended from Spanish Jews expelled from Spain in 1492, according to the FCC order. He immigrated to Mexico in 1921, and lived in Guatemala and Costa Rica before coming to the United States. The Liberman family speaks Spanish "a majority of the time," the FCC said.

Oscar Luis Kramer, meanwhile, owns 95 percent of Central Florida Spanish Broadcasting, which brought WMJK in Kissimmee, Fla., from Major Market Media Inc. Kramer was born in Cuba, as were his parents, and immigrated to the United States in 1961. He worked in Spanish-language radio in Miami before moving to Orlando, where he was active in Hispanic affairs.

An FCC policy statement says that minorities include ". . . Those of black, Hispanic surnamed, American Eskimo, Aleut, American Indian and Asiatic American extraction." The FCC, a spokesman said, followed the guidance of the Equal Employment Opportunity Commission, which refers only to "Hispanics," not "Hispanic-surnamed."
