Why do all FM radio stations end in odd numbers?
This is from the FCC: “The FM broadcast in the United States starts at 88.0 MHz and ends at 108.0 MHz. The band is divided into 100 channels, each 200 kHz (0.2 MHz) wide. The center frequency is located at 1/2 the bandwidth of the FM Channel, or 100 kHz (0.1 MHz) up from the lower end of the channel. For example, the center frequency for Channel 201 (the first FM channel) is 88.0 MHz + 0.1 MHz = 88.1 MHz…. AM and FM station assignments in other countries may not be made according these procedures. In some countries, an FM station may be assigned a frequency with an even decimal such as 106.2 MHz.” It’s so they don’t interfere with each other’s transmissions.
