The music on 91.5-FM WKHR is old and so are many of the volunteer DJs. But there's one voice among all the raisins that stands out: Bette Moss, who goes by the moniker "The Satin Doll." Moss may have some miles on her AARP card, but her velvety bedroom growl is so comfortable to listen to you just want to curl up in her lingo, as she spins classics from the Great American Songbook. With flashes of impish wit and a saucy sense of humor, the on-air Moss is aural sex for people of all ages. And close to her in listenability is Cleveland radio icon Tall Ted Hallaman, whose ham-on-wry stylings recall a different and mellower time on local radio. Those days may be gone, but their embers still glow at the low end of the dial.
