The Radio That Heard Everything

The idea: tuning is resonance; the number on the dial is a frequency.

Lan threads the dial cord inside an old radio while Beto holds the torch, with Ring and Pulse beside them.

Who is in this book

Every recurring character has a short tune, so you can tell who is on stage before a word is said. The tunes play only when you tap, and the Reading Access sound switch turns them off.

The Honest Page

Which parts of this story are true, stretched or made up?

True

  • A radio tuner works by resonance: its circuit rings strongly at one frequency, and turning the knob changes which one. Source
  • On a medium-wave dial the numbers are in kilohertz. 909 kHz is 909,000 waves a second, and each wave is about 330 metres long.
  • Many old radios move the tuner with a dial cord: a thin string looped round small wheels, which can slip off. Source

Stretched

  • A tuner stuck between two stations plays both. What we simplified: Real radios also pick up two stations when they are close together on the dial or when one is very strong.

Made up

  • The Mend Shed, Mr Okafor and his radio are made up. Ring and Pulse come from WaveForge.

Tell it back

Tell the story in your own words: who was there, what went wrong, and what they found out. Then the radio's old dial cord, coiled, for the shed's shelf of fixed things goes on your belt.
