9.5 Channel Assignments
The Channel Assignment tables on the following pages list the channel num-
ber, frequency and usage for Marine VHF communication.
Depending upon your selection, certain channels may be either simplex
(single frequency) or duplex (two frequency) 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 fre-
quency 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.
