OPERATING TNCThis transceiver has a built-in TNC which conforms to
the AX.25 protocol.  This protocol is used for
communications between TNCs.  The TNC accepts data
from your personal computer and assembles it into
packets.  It then converts packets to audio tones which
the transceiver can transmit.  The TNC also takes audio
tones from the transceiver, converts them to data for the
computer, and checks for errors in the data.
The TNC mainly functions in Command or Converse
mode.  First learn the difference between these two
modes.
¥Command mode
When you select Packet mode, the TNC enters this
mode.  A Òcmd:Ó prompt appears on the computer
screen.  You can type commands from the computer
keyboard to change the settings on the TNC.  When
in Converse mode, press [Ctrl]+[C] on the keyboard
to restore the Command mode.
¥Converse mode
The TNC enters this mode when a linkage with the
target station is established.  On the computer
keyboard, type an appropriate command and if
necessary a message, then press [Enter] or
[Return].  What you type is converted into packets
and transmitted over the air.  When in Command
mode, type CONVERSE to restore the Converse
mode; you can also type CONV or K instead.
For the commands supported by the built-in TNC, see
ÒTNC COMMANDS LISTÓ on page 99.
CONNECTING WITH A PERSONAL COMPUTERYou can use an optional PG-4W cable to connect the
transceiver with a personal computer.  For this cable,
contact your authorized KENWOOD dealer.Note:  Turn OFF the transceiver power before making the connection.
Note:  When the built-in TNC is ON, some internal frequency
relationships may induce an internal heterodyne and cause the squelch
to be opened unexpectedly.  Shifting the interference will solve this
problem.  Press [TNC]+ POWER ON to access ÒBEAT SHIFTÓ.  Press
[UP]/ [DWN] to select ÒUPPERÓ.  Press [OK] to complete the setting.
The default is ÒNORMALÓ.

AUTOMATIC PACKET/ POSITION REPORTING SYSTEM
Ò
The Automatic Packet/ Position Reporting System
(APRS
Ò) is a software program and registered
trademark of Bob Bruninga, WB4APR.  He has made
packet communications much more exciting than before.
This program allows you to track mobile stations on a
map which you recall on a computer screen.  Imagine
seeing one mobile station moving on the map which can
be scaled from .5 to 2000 miles.  You also may be
tracked on the computer screen of another station.
Stations to be tracked must transmit beacons at certain
intervals.  To track other stations, you usually need a
computer running the APRS, a transceiver, and a TNC.
To have them track you, you also need a GPS receiver.
It receives signals from the satellites to inform you of
your current geographical position.  GPS stands for
Global Positioning System.  The APRS interprets the
National Marine Electronics Association (NMEA) data
strings coming from the GPS receiver.  For further
information, consult Internet Web pages relating to the
APRS.  You may use one of the Internet search engines
to find correct URLs.
This transceiver includes a TNC and a program for
dealing with data formats supported by the APRS.  Its
display shows information each time correct APRS data
is received; you do not need a computer.  It also allows
you to manually enter position data (latitude/ longitude)
to transmit; use this function if you do not have a GPS
receiver.  Besides position data this transceiver can
receive or transmit the following information:1Receive only2Can be transmitted only when using a GPS receiver.This transceiver has a PC jack and GPS jack to connect
with a personal computer and a GPS receiver.  This
manual, however, does not describe APRS
communications which require these equipment.Note:u
Turn OFF the transceiver power before making the connections.
u
The GPS jack also accepts a 2.5 mm (1/10) 3-conductor plug.  You
may use the provided cable {page 1} to modify the cable end of your
GPS receiver.  The connection of each conductor (TXD/ RXD/ GND)
is the same as the plug on the PG-4W {page 53}.
