I doubt it. The radio is a public forum that has nothing to do with her. As long as he doesn't mention her at all, it should be fine. (I assume; I'm no lawyer.)
Similarly, he can have a blog, and her accidentally stumbling upon it should not count as a violation.
Sending any kind of email directly to her, however, is direct contact and probably a violation of the restraining order.
