If interested, the reason I don't like the radio analogy is that it presupposes that the configuration of the brain, and inputs isn't fundamentally the constituents of consciousness.
On the flip side, to fix the analogy: if I cut off the antenna of a radio, I would argue it ceases to become a radio by any reasonable definition (assuming we're talking about a device that receives radio waves and plays them back in the form of sound). You just have something that's very close to a radio. It has nothing to do with whether radio waves exist or don't.
As long as you agree that it's conceivable that there's experimentation (brute force or otherwise), then I think we're on the same page.
