  1. The upper portion of the 80 Meter band also is known as 75 Meters.
  2. 60 Meters consists of five discrete channels rather than a continuous band of frequencies like the other Amateur Radio bands.

Each Amateur Radio Band above is divided into sub-bands where various modes of communication, transmitting power limits, and license requirements apply. See the American Radio Relay League (ARRL) US Amateur Radio Frequency Allocations page for more detail.
