Working with the Call Logs
For every DSC call that your radio receives, the calling station, type of call, and date and
time of the call are recorded in the call logs. The latitude and longitude of the calling station
are also recorded if they are transmitted with a call.
There are three categories for calls that are logged: distress, position, and other. The
following table indicates where each type of call is located in the call logs.
