Simplex/Duplex Channe l Use
A.
A simplex channel is used for ship- to-ship communication. The transmit
And receive frequencies are the same.
Example: CH 22A 157.000 MHz, transmit & receive (USA mode)
B.
A duplex channel is a public correspondence, ship-to-coast channel
Which is mainly used by Marine Telephone Operators. A duplex channel
cannot be used for ship-to-ship communication because the transmit and
receive frequencies are not the same. Example CH 24 157.200 MHz transmit
and 161.800 MHz receive, (USA mode.)
NOTE:
A ll channels are factory programmed in accordance with FCC (USA) and IC
(Canada), and International regulations. Mode of operation cannot be altered from
simplex to duplex or vice-versa.
