I wish I knew who to go to. My parents live 20 miles west of Durham and have the same problem. I am lucky to live in the eastern part of the state because we get the Duke Radio Network for men's bball and football on FM 107.9. It would be nice if they would broadcast the women's games especially early in the season when they are unlikely to be on TV.
If someone can point us in the right direction, I'll be glad to become a part of a campaign to encourage more complete radio coverage for Duke Sports.
