Associated Black Charities hopes to boost donations this weekend with a radio-thon over two Baltimore gospel stations.

The fund-raiser is the highlight of ABC's annual campaign, which aims to raise more than $100,000 when it sends its message of self-sufficiency to the black community over WGBR and WCAO (Heaven 600). The radio-thon runs from 7 a.m. to 7 p.m. today and tomorrow, and from noon to 6 p.m. Sunday.

"This gives us an opportunity to define issues important and relevant to African-Americans . . . and to get that message out," said Kirk D. Fancher, director of development and marketing at ABC.

Donna Jones Stanley, executive director of ABC, said the radio-thon will replace major fund-raising concerts the group has held.

She said ABC gives the money it receives to groups that work to make members of the black community more self-sufficient. She said ABC fosters three major goals: family preservation, community development and economic development.

ABC receives contributions from individuals, businesses and the United Way of Central Maryland.

Among the organizations it has funded are the Baltimore Fuel Fund and Campaign for Our Children.
