Your Town's FM Dial, Written Down — Read the Hidden Data Inside Local Radio

Have you ever watched a car radio spell out the station's name and the song that's playing, and wondered where those words come from?

They are not in the sound. The station is broadcasting them as actual data, in the clear, riding alongside the music, to anyone with a receiver — and almost nobody who has listened to that dial for years ever finds out it has a written channel running underneath it. This project hands you the receiver. It also hands you the first honest lesson of radio, the one that separates people who own a listening station from people who own a gadget: learning to tell the difference between hearing nothing because nobody is transmitting, hearing nothing because they are transmitting but never say their name, and hearing nothing because your own equipment is quietly misconfigured.
