9. End the message by saying “ OVER ”. Release the microphone button
and listen.
10. If there is no answer, repeat the above procedure. If there is still no re-
sponse, try another channel.
9.2 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9)
Channel 16 may be used for initial contact (hailing) with another vessel.
However, its most important use is for emergency messages. This channel
must be monitored at all times except when actually using another channel.
It is monitored by the U.S. and Canadian Coast Guards and by other ves-
sels.
Use of channel 16 for hailing must be limited to initial contact
only. Calling should not exceed 30 seconds, but may be repeated 3 times at
2-minute intervals. In areas of heavy radio traffic, congestion on channel 16
resulting from its use as a hailing channel can be reduced significantly in
U.S. waters by using
Channel 9 as the initial contact (hailing) channel for
non-emergency communications. Here, also, calling time should not exceed
30 seconds but may be repeated 3 times at 2-minute intervals.
Prior to making contact with another vessel, refer to the channel charts in
this manual, and select an appropriate channel for communications after
initial contact. For example, Channels 68 and 69 of the U.S. VHF Charts are
some of the channels available to non-commercial (recreational) boaters.
Monitor your desired channel in advance to make sure you will not be inter-
rupting other traffic, and then go back to either channel 16 or 9 for your initial
contact.
When the hailing channel (16 or 9) is clear, state the name of the other
vessel you wish to call and then “
this is ” followed by the name of your vessel
and your Station License (Call Sign). When the other vessel returns your
call, immediately request another channel by saying “
go to ,” the number of
the other channel, and “over.” Then switch to the new channel. When the
new channel is not busy, call the other vessel.
After a transmission, say “ over ,” and release the microphone’s push-to-talk
( PTT ) 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 beginning 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.
