button on the microphone. Speak the name of the vessel you are calling followed
by “This is” and the name of your vessel and your call sign. Release the
PTT
and
listen for a reply. When the other vessel returns your call, acknowledge the call
with “go to”, the number of the new channel and “over”. Switch to the new channel
and listen for traffic. If necessary, wait for traffic to clear, and then call the other
vessel. As communication proceeds, end each transmission with “over”. When
communication with the other vessel is completed, end the last transmission with
your call sign and the word “out”. It is not necessary to end each transmission with
your call sign, just give your call sign at the beginning and end of each contact.
Remember to switch to Channel 16 when not actively communicating on another
channel.
3.3 Telephone Calls
You may use your
MT-550
transceiver to make telephone calls to persons on shore.
To do so requires the services of marine operators who operate on designated Public
Correspondence channels. There are several channels designated for this type of
traffic and to determine the channel being used in your area, ask someone with local
knowledge, contact a Harbor Master or other marine authority.
Call the marine operator and identify yourself with your vessel’s name. Normally
you contact a marine operator on their working channel rather than making initial
contact on Channel 16. The marine operator will ask for your intentions and
establish a payment method for the call (collect, credit card, etc.). When
arrangements are complete, your radio communication will be patched into the
telephone line. In conversing with a person on the phone it is important to use
normal radio communication procedures. You should say ”over” and release the
PTT
button at the end of each transmission. Both parties cannot speak
simultaneously as on normal telephone calls.
Usually there is a fee for marine operator services which is charged in addition to
any other charges associated with the call.
