1 .TH FM 1 "fmscan 0.99.1"
3 fmscan \- scan FM band for radio stations
24 is a program to scan a frequency band for radio stations, using the
25 video4linux interface introduced in 2.1.x series Linux kernels. It
26 shows which ones have a accumulated signal strength of 50% or higher.
31 Print a usage message to standard output, and exit.
34 Sets \fIdevice\fR as the device to tune. The default is
38 Starting frequency for scan, in MHz. Default: 87.9.
41 Ending frequency for scan, in MHz. Default: 107.9.
44 Increment between scanned channels, in MHz. Default: 0.2.
47 Signal strength threshold to consider a channel. Default: 50%.
49 This process can take a while, and results vary greatly depending on the
50 radio card in use. If your card's hardware cannot report signal
51 strength, it will not produce useful results.
53 This program may not do much if your radio card's driver doesn't support
54 fine tuning in 1/16000 MHz offsets. By default, v4l assumes 1/16 MHz
55 tuning units, which introduces evil rounding errors on many frequencies.
56 If in doubt, grep for VIDEO_TUNER_LOW in your driver's source.
58 Supports only tuner 0 on any given device.
