fmscan - scan FM band for radio stations
fm [ -h ] [ -d device ] [ -t tuner ] [ -s freq ] [ -e freq ] [ -i freq
] [ -q ]
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.
-h Print a usage message to standard output, and exit.
Sets device as the device to tune. The default is /dev/radio0.
Sets tuner as the tuner on the selected device to adjust. The
default is tuner 0. Most radio devices have only a single
Starting frequency for scan, in MHz. Default: 87.9.
Ending frequency for scan, in MHz. Default: 107.9.
Increment between scanned channels, in MHz. Default: 0.2.
Signal strength threshold to consider a channel. Default: 50%.
-q Quiet mode. Suppresses progress output.
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
Supports only tuner 0 on any given device.
