radioctl command displays or sets various variables
  that affect the radio tuner behavior. If a variable is present on the command
  line, radioctl prints the current value of this
  variable for the specified device. By default,
  radioctl operates on the
  /dev/radio device.
The options are as follows:
-a-w
    name=value-f
    file-nValues may be specified in either absolute or relative forms. The
    relative form is indicated by a prefix of
    ‘+’ or
    ‘-’ to denote an increase or decrease,
    respectively.
The exact set of controls that can be manipulated depends on the tuner. The general format (in both getting and setting a value) is
name = value
The name indicates what part of the tuner the control affects.
Write only controls:
up’ or
      ‘down’.Read-write controls:
on’ or
      ‘off’.on’ or
      ‘off’. Only for cards that allow
      forced mono.All the remaining controls (signal, stereo and card capabilities)
    are read-only and can be viewed using option -a.
