Notes:
1) Significant regional variations in both current band utilization and the intensity and frequency distribution of noise sources preclude one plan that is suitable for all parts of the country. These variations will require many regional frequency coordinators to maintain band plans that differ in some respects from any national plan. As with all band plans, locally coordinated plans always take precedence over any general recommendations such as a national band plan.
2) May be used for either repeater inputs or weak-signal as regional needs dictate
3) Division into channels and/or separation of uses within these segments may be done regionally based on needs and usage, such as for 2 MHz-wide digital TV.
4) These segments may also be designated regionally to accommodate alternative repeater splits.
5) Simplex FM calling frequency 927.500 or regionally selected alternative.
6) Additional FM simplex frequencies may be designated regionally.
