Inderdaad is in USA ieder kanaal 0,2 MHz breed en worden alleen de oneven honderdtallen KHz gebruikt als afstemfrequentie, volgens Wiki:
FM radio channel assignments in the U.S.
In the United States, frequency-modulated broadcasting stations operate in a frequency band extending from 87.8 MHz to 108.0 MHz, for a total of 20.2 MHz. It is divided into 101 channels, each 0.2 MHz wide, designated "channel 200" through "channel 300." In actual practice, no one (except the FCC) uses these channel numbers; the frequencies are used instead.
To receive a station, an FM receiver is tuned to the center frequency of the station's channel. The lowest channel, channel 200, extends from 87.8 MHz to 88.0 MHz; thus its center frequency is 87.9 MHz. Channel 201 has a center frequency of 88.1 MHz, and so on, up to channel 300, which extends from 107.8 to 108.0 MHz and has a center frequency of 107.9 MHz.
Because each channel is 0.2 MHz wide, the center frequencies of adjacent channels differ by 0.2 MHz.
