Effi Barry, wife of Mayor Marion Barry, will begin a daily radio show Monday featuring gospel music and discussion of city issues on radio station WYCB, a spokesman for the station said yesterday.

Spokesman Roosevelt Twyman described the show, which will air at 1 p.m., as a "good neighbor hour" in which Barry will mix selections of religious music, conversation with studio guests and on-the-air telephone calls from listeners. Each show will be built around a single topic, he said.

Twyman said that the topic on Monday's inaugural show, and possibly for the rest of the week, will be senior citizens. Barry's guests will probably be from the city's Office on Aging.

Barry will receive a salary for hosting the show, Twyman said, but he declined to reveal what it is. Barry could not be reached for comment.

Barry gave up a $38,000-a-year job with Pacific Consultants a year ago shortly before her son, Marion Christopher, was born. The child celebrated his first birthday yesterday.

WYCB mainly reaches the city's black community, especially older, churchgoing residents. The station's format is strictly gospel music and informatinal programming.

Twyman said neither the station nor Barry had made a commitment to continue the show for any set period of time. "We're just going to see how it works out," he said. "We believe that people will just call in because of who she is."

He said the station approached Barry first and asked if she would be interested in doing the show. He said he did not know if Barry had any work experience in radio, but said the station did not ask her to conduct a formal audition because officials of the station had heard her as a guest on other call-in programs.

"We think she sounds very good on the air," Twyman said.
