NAME

       fmscan - scan FM band for radio stations

SYNOPSIS

       fm [ -h ] [ -d device ] [ -t tuner ] [ -s freq ] [ -e freq ] [ -i freq ] [ -q ]

DESCRIPTION

       fmscan  is  a  program  to  scan  a  frequency  band  for radio stations, using the video4linux interface
       introduced in 2.1.x series Linux kernels.  It shows which ones have a accumulated signal strength of  50%
       or higher.

   OPTIONS
       -h     Print a usage message to standard output, and exit.

       -d device
              Sets device as the device to tune.  The default is /dev/radio0.

       -t tuner
              Sets  tuner  as  the  tuner on the selected device to adjust.  The default is tuner 0.  Most radio
              devices have only a single tuner.

       -s freq
              Starting frequency for scan, in MHz.  Default: 87.9.

       -e freq
              Ending frequency for scan, in MHz.  Default: 107.9.

       -i freq
              Increment between scanned channels, in MHz.  Default: 0.2.

       -t percent
              Signal strength threshold to consider a channel.  Default: 50%.

       -q     Quiet mode.  Suppresses progress output.

BUGS

       This process can take a while, and results vary greatly depending on the radio  card  in  use.   If  your
       card's hardware cannot report signal strength, it will not produce useful results.

       This  program  may  not  do  much  if your radio card's driver doesn't support fine tuning in 1/16000 MHz
       offsets.  By default, V4L2 assumes 1/16 MHz tuning units, which introduces evil rounding errors  on  many
       frequencies.

       Supports only tuner 0 on any given device.
