Conventionally, radios have used 25 KHz spacing, so if you owned 2 frequencies right next to each other, you may own 861.0150 MHz and 861.0200 MHz, but now under the new 12.5 KHz spacing regulations, in that space, you could be assigned frequencies 861.0150, 861.01750, and 861.0200. This change allows for more effective spectrum management.
