Frequency Spacing (Optional)
Some communication radios have the ability to tune either 25-kHz spacing (118.000 to 136.975 MHz) or 8.33-kHz spacing (118.000 to 136.990 MHz) for 760-channel or 3040-channel configuration. When 8.33-kHz channel spacing is selected, all of the 25-kHz channel spacing frequencies are also available in the complete 3040-channel list.
The image below shows a configuration that has a radio installed that can be configured in both the 25-kHz and 8.33-kHz channel spacing. If no radios are installed that have this feature, the option will not exist to change the channel spacing. If two radios are installed and only one has this feature, the channel spacing option will only be available on the specific radio that has the feature.
