10.5 Channel Assignments
The Channel Assignment tables on the following pages list the channel number,
frequency and usage for Marine VHF communication.
Depending upon your selection, certain channels may be either simplex (single
frequency) or duplex (two frequencies) as indicated in the tables. On simplex
channels, your transceiver transmits and receives on the same frequency. On duplex
channels, your transceiver transmits on one frequency and receives on another
frequency. You may communicate with shore stations on both simplex and duplex
channels, but because of the frequency offset, you cannot communicate with other
vessels on a duplex channel.
Channel 16 is the International Distress, Safety and Calling channel. All vessels
equipped with VHF transceivers are required to monitor channel 16.
