He purchases one of the radios, of course. He can afford it, and who wouldn't purchase one if they can afford it?
He listens to it on the headset while he does paperwork in his office. He can't afford the distraction, but he can't afford not to listen, either. There's no obvious reason why the market price of eggs in Absalom would be relevant to his job, but if it turns out that it is, the lack of obvious relevance is no excuse.
He listens to prayers for half a minute, once. He doesn't make that mistake again.
One evening he changes it to the frequency that tells adventure stories. He enjoys the adventure story more than just about anything else that's happened in the past year, and feels vaguely guilty about it.
Well, Freedom Radio's running because we think the truth can do very nearly everything. I can tell you what I'd do if my child was sick, and maybe it'll save yours. I can tell you if there's a war brewing, so you can hide what's precious to you when there are soldiers marching towards it. There are some things terribly wrong, in our world, and a world united can beat them into the dust, and a world that doesn't know what's true and what's a lie doesn't stand a chance. And I can tell you about the world to come, and line up some people who've been there who can tell you what you'll answer for when you face the Judge. There's a lot of things in this world that work because people are ignorant. And Freedom Radio is going to make sure that no one will ever be able to take advantage of your ignorance again.
His hands are shaking. This is, objectively speaking, ridiculous; only the guilty have reason to fear the truth. What she's saying is — idealistic, obviously, there's much that the truth can't fix once it's been broken, but there's something beautiful about it anyways.
He listens to the whole news segment. Partway through he stops with his actual work and starts just taking notes on what she's saying. He'll pay for it in lost sleep, but — if the broadcast had been available two and a half decades sooner, his mother might still be alive.
