SYNOPSIS

gradio

[ -c [ -v level ] [ -f freq ] [ -m +|- ] ] [ -d filename ] [ -h ] [ -V ]

DESCRIPTION

gradio is a Gtk-based X11 application to control the frequency, volume, and mute/unmute state of an FM radio card. Gradio uses the video4linux interface found in 2.1.x and later Linux kernels.

OPTIONS
-d 
filename

Use filename as the device to control. The default is set at compile time.

-h

Display usage information and exit.

-V

Display version information and exit.

The remaining options are available on the command-line if -c (command line) is specified. Otherwise, the gradio GUI will appear.
-v 
level

Set volume to level which must be a number between 0 and 11.

-f freq

Set frequency to freq megahertz.

-m

If a + follows, the card is muted. If a - follows, it is unmuted.

SEE ALSO

For more information on video4linux, see its web page at http://roadrunner.swansea.uk.linux.org/v4l.shtml.

More documentation available in /usr/doc/gradio.

BUGS

Supports only a single tuner on a single radio device.

Older versions of Gradio also supported direct port access for some common types of radio cards. This is no longer supported with the availability of Linux 2.2.0 pre-releases.
