RADIO INSTRUMENT:

Two radios tuned to different channels, converse
One radio tuned between channels, detects rhythms of interference
Two radios tuned to the same channel, one digital, one analogue,
one sending messages to the other from the future
Three radios, all tuned between stations, sing a beautiful noise
Three radios arranged in a circle, all tuned to different stations
A corridor of radios all tuned between channels
A corridor of radios, alternately digital & analogue, tuned to the
same station
One car radio tuned to AM utilises the travelling of the car to find
transmissions.
