Programming A Group Code - Kenwood TH-D7A Instruction Manual

PROGRAMMING A GROUP CODE

Using a group code relieves you from receiving
unwanted packets. The APRS on this transceiver
supports the following three types of group codes.
All calls:
Program a 6-digit code that always starts with AP. You
will receive all APRS packets which include AP in group
codes. It does not matter whether or not the subsequent
4 digits match. The default on this transceiver is
APK001; K001 stands for KENWOOD Ver.1.
Note: APRS packets, which are generated via various methods, include
various codes instead of group codes. Using "All calls" allows you to
receive packets which include the following codes.
G P S S Y M Q S
A L L S K Y W R N M A
Special:
Enter "SPCL". You will receive only APRS packets that
include SPCL as a group code. This code is generally
programmed by all stations at a special event.
Alternate net:
Program any other code with a maximum of 6 digits.
You will receive only APRS packets that include the
exact same code. In order to reject other packets, this
code should not include characters specified by the
above two types.

Note: Menu 2–A allows you to enter up to 9 digits (not 6 digits) because
of possible future enhancement of the group code system.
