NAME
fmscan - scan FM band for radio stationsSYNOPSIS
- fm [ -h ] [ -d device ] [ -s freq ] [ -e freq ] [ -i freq ]
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.
- -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%.
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, v4l assumes 1/16 MHz tuning units, which introduces evil rounding errors on many frequencies. If in doubt, grep for VIDEO_TUNER_LOW in your driver's source.
Supports only tuner 0 on any given device.
