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. 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.
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.
