USER MMSI
To use the DSC feature you must be registered with the
appropriate licensing authority (AMSA in Australia) who
will issue you with your unique user MMSI number. You can
then enter this into your GX600D to enable DSC operation.
Having a registered user MMSI means you can be identified
much quicker in an emergency.
Your GX600D is shipped from the factory without a user
MMSI number. It is up to the user to obtain a valid MMSI
from the appropriate licensing authority and enter the MMSI
into the radio to enable DSC operation.
GROUP MMSI
The Group MMSI is used for DSC Group Calls. A Group Call
provides a method for all vessels with a common interest
(eg: a yacht club or a fishing fleet) to be contacted with
one DSC call. Group MMSI’s are usually issued by a club
or organisation for use by members participating in group
activities (such as yacht racing etc).
RANGE
The range of VHF transmissions depends on antenna height,
transmitter power and the terrain over which the signals
pass. Ship to ship communications should be possible
over at least 8 nautical miles and up to about 27 nautical
miles. Ship to shore ranges will often be greater due to the
increased height of the shore antenna and communications
of 25 to 50 nautical miles are possible.
