Jeanette Eaton Johnson, 41, who had been known to citizens' band radio users as "Slim Goodie," died of hepatitis Monday at George Washington University Hospital.

Mrs. Johnson first took to the air-waves five years ago following her retirement from the Treasury Department for reasons of health.

During the years she operated her CB station from her bedroom on Adams Street NW. she helped authorities find lost children, rescue stranded motorists, and relay messages. She received awards from the D.C. police and fire departments for her help during city emergencies.

Mrs. Johnson was a member of the Watergate Senators, a Washington citizens' band club.

She also had taken in runaway children, helped manage and advise a fledgling rock band, and did volunteer work for the D.C. Department of Recreation.

Once asked how she chose the "handle," or air-name, "Slim Goodie," she said that she was both "slim" and "good."

Mrs. Johnson was born in Washington. She was a graduate of Dunbar High School. She then worked as a secretary at the Treasury Department.

Her marriage to Harold Johnson ended in divorce.

She is survived by her daughter, Sheryl D.M. Johnson, of the home in Washington: her parents, Mr. and Mrs. Harold G. Eaton Sr., of Washington: two brothers. Harold G. Eaton Jr., of Lanham, and the Rev. David H. Eaton, who is pastor of All Souls Unitarian Church in Washington: two sisters. Mrs. Ordee Trotter, of Cleveland, and Patricia F. Eaton, of Washington.
