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.
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.
