Special Notes on USA Channel Usage

1. LOW POWER (1 W) only.

2. Receive Only.

3. LOW POWER (1 W) initially. Override to HIGH POWER by holding down H/L key before transmitting. Used normally in bridge-to-bridge communications.

4. Lightly shaded simplex channels 03A, 21A, 23A, 61A, 64A, 81A, 82A, and 83A cannot be lawfully used in U.S. waters unless special authorization is obtained from the U.S. Coast Guard. Not for use by the general public.

5 . The letter “A” illuminated by the channel number indicates the USA channel is simplex.

This same channel is always duplex when selecting International. There is no “A” refer- ence for International channels. The letter “B” is only used for some Canadian “Receive only” channels.

6. Channel 70 is designated for use exclusively for Digital Selective Calling (DSC), such as Distress, Safety, and Ship Calls. No voice communication is allowed on CH70.

This channel is only available on DSC enabled radios.

KEY: S = Simplex operating channel; D = Duplex operating channel.
