1 .TH FM 1 "fmscan 1.0.2"
3 fmscan \- scan FM band for radio stations
29 is a program to scan a frequency band for radio stations, using the
30 video4linux interface introduced in 2.1.x series Linux kernels. It
31 shows which ones have a accumulated signal strength of 50% or higher.
36 Print a usage message to standard output, and exit.
39 Sets \fIdevice\fR as the device to tune. The default is
43 Sets \fItuner\fR as the tuner on the selected device to adjust. The
44 default is tuner 0. Most radio devices have only a single tuner.
47 Starting frequency for scan, in MHz. Default: 87.9.
50 Ending frequency for scan, in MHz. Default: 107.9.
53 Increment between scanned channels, in MHz. Default: 0.2.
56 Signal strength threshold to consider a channel. Default: 50%.
59 Quiet mode. Suppresses progress output.
61 This process can take a while, and results vary greatly depending on the
62 radio card in use. If your card's hardware cannot report signal
63 strength, it will not produce useful results.
65 This program may not do much if your radio card's driver doesn't support
66 fine tuning in 1/16000 MHz offsets. By default, V4L2 assumes 1/16 MHz
67 tuning units, which introduces evil rounding errors on many frequencies.
69 Supports only tuner 0 on any given device.
