10.5  GROUP CALL
This feature allows the user to contact a group of specic vessels using DSC 
radios with the group call function to automatically switch to a desired channel 
for voice communications. This function is very useful for yacht clubs and vessels 
traveling together that want to collectively make announcements on a predeter-
mined channel. Up to 32 group MMSIs may be programmed.
10.5.1  Setting up a Group Call
For this function to operate, the same group MMSI (Maritime Mobile Service 
Identity Number) must be programmed into all the DSC VHF radios within the 
group of vessels that will be using this feature. To understand Group MMSI 
programming, rst a ship MMSI has to be understood.
Ship MMSI: The rst three digits called MID (Mobile Identity Group) of a ship 
MMSI denote the country where the ship’s MMSI is registered. The last 6 digits 
are specic to the ships ID.
Ship MMSI Example: If your MMSI is “366123456”, “366” is MID which denote 
the country and “123456” is your ships MMSI.
Group MMSI:
  Group MMSI numbers are not assigned by the FCC or other organizations 
licensed to assign ship MMSI numbers. 
   The rst digit of a group MMSI is always set to “0” by International rules. All 
Standard Horizon radios are preset so when programming a group MMSI 
the rst digit is set to “0”. 
  The USCG recommends programming the MID of a ship MMSI into the 

Page 63
GX6000
Second, Third and Fourth digits of the group MMSI as it denotes the area 
the ship is located in. 
  The last 5 digits are decided upon by persons in the group. This is an impor-
tant step as all radios in the group must contain the same group MMSI so 
they can be contacted by each other. There is a chance that another group 
of vessels may program in the same group MMSI. If this happens, simply 
change one or more of the last 5 digits of the group MMSI.
1.  []  “SETUP”  “DSC SETUP”  “GROUP DIRECTORY”
2.  Rotate the DIAL/ENT  knob  to  select  “ADD”,  then

space in the name.

10.6  POSITION REQUEST
Advancements in DSC have made it possible to poll the location of another 
vessel and show the position of that vessel on the display of the GX6000. 
Standard Horizon has taken this feature one step further, if a compatible GPS 
chart plotter is connected to the GX6000, the polled position of the vessel is 
shown on the display of the GPS chart plotter making it easy to navigate to 
the location of the polled vessel. This is a great feature for anyone wanting to 
know the position of another vessel. For example, your buddy that is catching 
sh or nding the location of a person you are cruising with.
NOTE
The other vessel must have an operating GPS receiver connected to 
its DSC radio and must not have its radio set to deny position requests.  
(Refer the section “10.4 INDIVIDUAL CALL” to enter information into 
the individual directory).
10.6.1  Setting up a Position Request Reply 
The GX6000 can be set up to automatically (default setting) or manually send 
your position when requested by another vessel. This selection is important if 
you are concerned about someone polling the position of your vessel that you 
may not want to. In the manual mode you will see the MMSI (Maritime Mobile 
Service Identity Number) or persons name shown on the display allowing you 
to choose to send your position to the requesting vessel.
1.  []  “SETUP”  “DSC SETUP”  “POSITION REPLY”
2.  Rotate the DIAL/ENT  knob  to  select  “AUTO”  or 
“MANUAL”.  In  “AUTO”  mode,  after  a  DSC  POS 
request is received, the radio will automatically trans-
mit your vessel’s position. In “MANUAL” mode, the 
display of the GX6000 will show who is requesting 
the position and the [YES] soft key on radio has to 
be pressed to send your position to the requesting 
vessel.
