Tom Sexton leans forward into a microphone. Coming up by request, he says in a softened-for-radio Appalachian drawl, going out to Sporty Black from his wife, this is Kendrick Lamar with LOVE. The melodic R&B track then begins to emanate from the heart of this small eastern Kentucky town. Tonights shows are targeted for a very specific audience. People like Sporty Black. More than 5,000 men are incarcerated in the six federal and state prisons in the broadcasting range of WMMT. Every week, for almost 20 years, the station has produced a show called Calls From Home that broadcasts recorded messages from the inmates friends and family members. WMMT bills itself as a 24 hour voice of mountain people, and as far as the station is concerned, if the inmates can tune in, then they are mountain people too. Theyre here and part of our communities, says Elizabeth Sanders, WMMTs co-general manager. Anything we can do to help make the barriers between them and their families a little bit less, then were fulfilling part of our mission as the radio station here, she adds. The show has become something of a national phenomenon. Every Monday night calls flood in to the station. Some of the calls come with children discussing a report card, a happy birthday rendition, or more somber family news. The costs of calling prisons directly ... have been rising for years, reaching in excess of $10 a minute. Having a toll-free number can help families keep in touch a little bit more, says Sanders.
