the mic and saying “go to,” the number of the other channel, say “over” and
release the PTT button on the mic. 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.
5.7 MAKING TELEPHONE CALLS
To make a radiotelephone call, use a channel designated for this purpose.
Check with your local marina to learn which channels are used for radio-
telephone trafc. Channels available for such trafc are designated Public
Correspondence channels on the channel charts in this manual. Some
examples for USA use are the channels 24, 25, 26, 27, 28, 84, 85, 86, and
87. Call the marine operator and identify yourself by your vessel’s name, the
marine operator will then ask you how you will pay for the call (telephone
credit card, collect, etc.) and then link your radio transmission to the tele-
phone lines.
The marine telephone company managing the VHF channel you are using
may charge a link-up fee in addition to the cost of the call.
5.8 OPERATING ON CHANNELS 13 AND 67
Channel 13 is used at docks, bridges and by vessels maneuvering in port.
Messages on this channel must concern navigation only, such as meeting
and passing in restricted waters.
Channel 67 is used for navigational trafc between vessels.
By regulation, power is normally limited to 1 Watt on these channels. Your
radio is programmed to automatically reduce power to this limit on these
channels. However, in certain situations it may be necessary to temporarily
use a higher power. See page 26 (
key) for means to temporarily over-
ride the low-power limit on these two channels.
