10 SX 35 DSC
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 transmis-
sion. Both parties cannot speak simultaneously as on normal telephone calls.
Usually there is a fee for marine operator services which is charged in addi-
tion to any other charges associated with the call.
Prohibited Communication
The following communications are prohibited by regulations and violators
are subject to penalties.
• False distress or emergency messages (including false DSC distress).
• Messages to “any vessel” except in emergencies and radio tests.
• Messages to or from a vessel on land.
• Transmission while on land.
• Obscene, indecent, or profane language.
