Spans 87.8 MHz to 108.0 MHz in 200 kHz intervals
101 possible stations
example: 91X runs from 91.0–91.2 MHz (centered at 91.1)
Nominally uses 150 kHz around center
75 kHz on each side
30 kHz for L + R (mono) 15 kHz audio capability
30 kHz offset for stereo difference signal (L - R)
Again: figure exaggerated
75 kHz from band center, modulation is > 1000 times slower than carrier, so many cycles go by before frequency noticeably changes
