PITTSBURGH (AP) _ Bob Mates hadn't worked for three months when he spun the radio dial and landed on a lucky number.

He found the frequency of a station that let him and dozens of others plead for work on the airwaves. But unlike most of the other resume readers, Mates got a job through WTAE-AM's afternoon talk show.

He began work Monday as a part-time telephone salesman at Tri-State Hearing Aid Dispensing Centers in Castle Shannon, a Pittsburgh suburb.

''I said if you're looking for someone who's persistent, professional and polite, then you just heard him,'' said Mates, who is blind.

At least three others - a housewife, an accountant and a financial planner - have found work because they read their resumes on two of Doug Hoerth's shows last month, said WTAE executive producer Tina Simonetti.

She said about 125 employers have called the station for the numbers of about 75 resume readers. The station was to repeat the job service Tuesday, giving callers 90 seconds each to sell themselves.

Mates, of Wilkinsburg, was hired by Tri-State managing partners Robert Duncan, who heard him on WTAE, and Robert Marchetti, who heard about him from his fiancee.

''He was enthusiastic, he had a good voice and I could see he would have empathy with the patients,'' Duncan said.

Also finding work after 2 1/2 years of looking was housekeeper Thelma Thindle. She tried for three hours to get on the air, and then planned to calmly tell how she had cleaned jewelry stores for 14 years. It didn't work.

''I was going to take about 60 seconds, but I went through it in about 20,'' said Ms. Thindle of Trafford. ''I was so nervous, with all these important people going before me.

''I felt like Carol Burnett, like she used to dress up at the end of her show with her old shoes and the mop over her shoulder.''

Nevertheless, she's cleaning a family's home two days a week and has leads on other jobs from her new bosses.
