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
APK002; K002 stands for KENWOOD Ver. 2.
Note:  APRS packets, which are generated via various methods,...

13
PROGRAMMING A PACKET PATH
A packet path specifies how APRS data should be
transferred via one or more repeaters.  A repeater, which
is used for packet transfer, is commonly called a
digipeater.  This came from a digital repeater.  A
digipeater is usually located on a mountain top or high
building.  Unlike a voice repeater, it operates on a
simplex frequency.  Each volunteer who installs a
digipeater programs it either as a WIDE or RELAY type.
Generally a WIDE transmits packets over much greater...

SELECTING PACKET TRANSMIT METHOD
Select the operation method for transmitting APRS data.
The table concludes how operations differ depending on
the selection:
1Access Menu 2ÐC (DATA TX), then press [OK].

SELECTING PACKET TRANSMIT INTERVAL
You can change the interval for automatically transmitting
APRS data.  Access Menu 2ÐD (TX INTERVAL) and
select 0.2, 0.5, 1, 2, 3, 5, 10, 20, or 30 minutes.  The
default is 5 minutes.
Note:
uWith ÒAUTOÓ in Menu 2ÐC and Beacon ON, pressing [OK] to
complete the setting causes the APRS data to be immediately
transmitted.  After that, APRS data is transmitted at intervals of the
selected period.
uWhile signals are present, APRS data is not transmitted after the
interval....

SELECTING A DISPLAY AREA
Each time new APRS data is received, the frequency
display is interrupted.  If this interruption annoys you too
much, access Menu 2ÐG (DISPLAY AREA) to select
ÒONE LINEÓ.  The transceiver then will not exit the
frequency display when receiving new data.  It will use
the bottom of the frequency display to show an indicator
(nP or nS) and a call sign; ÒnPÓ and ÒnSÓ designate New
Position and New Status respectively {page 4}.  The
default is ÒENTIRE DISPÓ.
