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.
