The Manual’s Lesson
Under candlelight, she flipped past the warnings and got to the practical pages: The ATS-20 (and its successor, the ATS-20+ )
BAND+ / BAND-: Cycles through pre-configured bands: FM, LW, MW, and various SW (Shortwave) segments. VOL+ / VOL-: Adjusts the volume level (typically 0–63). FM: 64–108 MHz (default 87–108) SW: 2
“FINAL STEP: Turn the volume knob fully counter-clockwise until you feel a click past ‘0.’ This is not ‘MUTE.’ This is ‘MEMORY.’ The radio will then listen to you. Speak your deepest secret into the silence. The ATS-20 will broadcast it once, on every frequency, for one second, to every receiver on Earth. This cannot be undone. Do not turn the knob past ‘0’ unless you are prepared to be truly heard.”
Yes, there is a secret engineering menu that no printed ATS-20 radio manual includes.
