After a transmission, say “over”, and release the PTT (Push-To-Talk) switch.
When all communication with the other vessel is completed, end the last
transmission by stating your Call Sign and the word “out”. Note that it is not
necessary to state your Call Sign with each transmission, only at the begin-
ning and end of the contact.
Remember to return to Channel 16 when not using another channel. Some
radios automatically monitor Channel 16 even when set to other channels or
when scanning.
3.5 OPERATING ON CHANNEL 13
Channel 13 is used at docks, bridges and for maneuvering in port. Messages
on this channel must concern navigation only, such as meeting and passing
in restricted waters. In emergencies and when approaching blind river bends,
High power is allowed. Pressing the
key will change the power output
from Low Power (1 Watt) to High (5 Watts: HX150, 2.5 Watts: HX100). When
you change from this channel then return to it, low power will be automati-
cally selected.
3.6 OPERATING ON CHANNEL 67
When channel 67 is used for navigational bridge-to-bridge traffic between
ships, High power may be used temporarily (in the USA band) by pressing
the
key. When you select this channel again, the transceiver will revert
to low power.
3.7 SIMPLEX/DUPLEX CHANNEL USE
Refer to the section “ 9. VHF MARINE CHANNEL CHART ASSIGNMENT”
for instructions on use of simplex and duplex channels.
NOTE
All channels are factory-programmed in accordance with FCC (USA),
Industry Canada and International regulations. The mode of opera-
tion cannot be altered from simplex to duplex or vice-versa. Simplex
(ship to ship) or duplex (marine operator) mode is automatically acti-
vated, depending on the channel and whether the USA, International
or Canadian operating band is selected.
