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.
