PROGRAMMING A MESSAGE GROUP CODE
Access Menu 3S0 .
Use a message group code to exchange messages only
among your group members. With one or more message
group codes programmed, you will receive messages
that include the same group code(s), besides messages
addressed to you. If you program one or more bulletin
group codes, you will not receive bulletins addressed
to other specific groups. You can program any desired
code using alphanumeric characters; up to 9 characters
for messages, and up to 4 characters for bulletins. You
can also program up to 6 codes at the same time; each
code must be separated by a comma (,). If you program
3 message group codes, for example, you will receive all
messages that include one of the 3 codes. If you program
3 bulletin group codes, you will reject bulletins addressed
to specific groups which do not use any of the 3 codes.
• You can enter 0 to 9, A to Z, , (comma), and –. For
messages, “
” is also selectable.
• The keypad on the microphone also is available to enter
alphanumeric characters.
• In order to include a message group code in your outgoing
packet, enter a group code in place of a call sign. To include
a bulletin group code, enter it following BLN#; for example,
“BLN#ABC” where ABC is a group code. Use up to 9
characters for a message group code or up to 4 characters
for a bulletin group code.
Note: Unlike a message, a bulletin including a group code will be
received by stations who do not program any bulletin group code.
