10.10 MAKING TELEPHONE CALLS
To make a radiotelephone call, use a channel designated for this purpose, The
fastest way to learn which channels are used for radiotelephone traffic is to
ask at a local marina. Channels available for such traffic are designated
Pub-
lic Correspondence
channels on the channel charts in this manual. Some
examples for USA use are 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 telephone 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.
10.11 OPERATING ON CHANNELS 13 AND 67
Channel 13 is used at docks and 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 traffic 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 chan-
nels. However, in certain situations it may be necessary to temporarily use a
higher power. See page 23 (H/L key) for means to temporarily override the
low-power limit on these two channels.

3. Press the [

nel that was selected in step 2.
If a transmission is received on the channel selected
in step 2, the

will dual watch to CH16.
