Editing FM broadcast band (section)

===Deviation and bandpass===
Normally each channel is 200&nbsp;[[Hertz|kHz]] (0.2&nbsp;MHz) wide, and can pass [[Broadcasting|audio]] and [[subcarrier]] frequencies up to 100&nbsp;kHz. [[Frequency deviation|Deviation]] is typically limited to 150&nbsp;kHz total (±75&nbsp;kHz) in order to prevent [[adjacent-channel interference]] on the band. Stations in the U.S. may go up to 10% over this limit if they use non-stereo [[subcarrier]]s, increasing total [[modulation]] by 0.5% for each 1% used by the subcarriers. Some stations may limited to (±50&nbsp;kHz) deviation in order to reduce transmitted bandwidth so that additional stations can be squeezed in.
