Seems to me that this is primarily about theism and is not about a debate on naturalism and science, irrespective of whether the topic is the TofE or anything else, since I'd imagine that the target audience of Premier Christian Radio are theists who accept that supernatural agency may be at work in the Universe.
I doubt that they get all that many listeners who are who aren't already committed theists - to me they are occupying the same apologist territory as the likes of 'Answers in Genesis'.
