INDIANAPOLIS -- Nationally syndicated radio talk-show hosts Bob Kevoian and Tom Griswold have made a career out of saying naughty things on the air.
From now on, they say they're going to be on good behavior.
Griswold -- co-host of the ''Bob & Tom Show'' heard on more than 130 stations -- said he has no intention of testing a zero-tolerance rule on indecency issued Wednesday by Clear Channel Communications, which owns the show's flagship station in Indianapolis.
Clear Channel, the nation's largest radio station chain, owns some 1,200 stations, including WFBQ, the show's home base.
''We're going to do a show that a soccer mom can listen to with her kids in the car,'' Griswold told The Indianapolis Star for a story Thursday.
Clear Channel issued new rules on on-air indecency on the eve of the second congressional hearing this month on broadcast indecency. The chain announced Wednesday that it was suspending shock jock Howard Stern's show because it violated the new standards.
Clear Channel announced the policy a day after it severed ties with a Florida disc jockey whose sexually explicit work drew a proposed fine of $755,000 from the Federal Communications Commission.
Indianapolis-based Emmis Communications, which owns 27 radio stations across the nation, also is preparing new restrictions on indecent content.
Rick Cummings, president of Emmis' radio division, said attorneys are reviewing details for the policy.
The FCC last week fined Emmis $28,000 for material broadcast in 2001 on an Emmis station in Chicago.
Congress is considering increasing the maximum fine for indecency from $27,500 to $275,000, a move that the FCC endorsed even before the tumult over singer Janet Jackson's exposed breast during the nationally televised Super Bowl halftime show.
Griswold and Kevoian have built a reputation based on humor and music laced with sexual innuendo and off-color references. They have incurred one FCC penalty in more than 20 years of broadcasting, and their show was the target of a 1985 advertising boycott by a group called Decency in Broadcasting.
Under FCC rules and federal law, radio stations and over-the-air television channels cannot air material containing references to sexual and excretory functions between 6 a.m. and 10 p.m., when children may be tuning in. The rules do not apply to cable and satellite channels and satellite radio.
Griswold said it is difficult to judge what is or is not acceptable by tracking material that has drawn fines.
''The rules are very vague,'' he said. ''I'm not going to take the chance of being anywhere near the line. We have pulled way, way back.''
