Hello! I'm asking this on behalf of someone else - he's read most or all of DFW's books, essays and interviews, so the answer to his q could be in any of the above. He tried asking various AIs but hilariously/pathetically they made up fake passages instead of saying they didn't know. I thought actual humans might know better. Anywhooo, his q -

There's a very brief passage, possibly in Infinite Jest, possibly in The Pale King, maybe elsewhere, where he describes how good it feels when you find a radio dj programming music that's on your same wavelength. (The word "wavelength" isn't actually used, I don't believe.) Any idea what/where this passage is?
