The

Codes.
Group Calling allows you to call members of your group simultaneously. However, to do
this, you need to follow a certain format (see below) when programming your TX Selcall
ID.

- and - [A] is the CCIR Assigned Group Tone Code
Example:
If one group comprises 10 members with Selcall IDs the ID numbers could be as follows:

all in TSQ mode at CH20
If someone transmits ID 1234A on CH20, all of the above units will open their Tone
Squelched Receiver.
Group Calls and ordinary Selcalls can be differentiated in the following manner:
Group Call - Low tone beeps
