1. GETTING STARTED

ber of the other channel, and "over". Then switch to the new channel. When the new
channel is not busy, call the vessel.
After a transmission, say "over", and release the PTT (Push-To-Talk) switch on the
microphone. When all communication with the vessel is completed, end the last trans-
mission by stating your callsign and the word "out". Note that it is not necessary to
state your callsign with each transmission, only at the beginning and end of the con-
tact.
Remember to return to CH16 when not using another channel. Some radios automat-
ically monitor CH16 even when set to other channels or when scanning.
1.3 How to Make 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 ma-
rina. Channels available for such traffic are designated Public Correspondence
channels on the channel charts in the Appendix. 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 then asks you how you want to
pay for the call (telephone credit card, collect, etc.) and then link your radio transmis-
sion to the telephone lines.
The marine telephone company managing the VHF channels you are using may
charge a link-up fee in addition to the cost of the call.
1.4 Channels 13 and 67 (USA channel group only)
Channel 13 is used at docks and bridges and by vessels maneuvering in port. Mes-
sages 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 pro-
grammed to automatically reduce power to this limit on these channels. However, in
emergency situations it may be necessary to temporarily use a higher power. See
page 2-1 (H/L key) for how to temporarily override the low-power limit on these two
channels.
