PARTS REQUIRED: one radio, dead, the kind with a dial not a screen. A room. Your own breathing, which you will need to stop noticing.
STEP ONE.
There is no step one. This is the first warning, not the first instruction. Everything that claims to be a beginning is lying to you gently, the way static lies — it sounds like it's about to resolve into a station, into a voice, into something with a name, and it never does. You will be tempted to call the hiss "the start." Don't. The hiss was already going before you turned the knob. You just arrived late to something enormous and indifferent.
Sit with the radio off. This is not step one either. This is the part before parts, where you pretend you're ready.
Turn it on only when you've stopped expecting a voice to greet you. If a voice greets you, you've built the wrong machine.
