Packet Communication
Packet communication is a high-speed data communication system transmitting a package of data
generated through a personal computer. The use of Digi-peaters (relay stations) offers communica-
tions with DX stations (distant stations). For packet communication, a personal computer, DSB-9
cable and the optional EJ-50U (TNC unit) are required in addition to this unit.
The EJ-50U is equipped with a Digi-peater function. For detailed information, please refer to the
instruction manual of the EJ-50U.
When using EJ-50U
Connect the EJ-50U with a personal computer.
1.Connect the EJ-50U and DSUB9 connecter to this unit following the figure below.
A sheet attached to the place meant for the DSUB9 connecter can be removed easily
by pressing from the inside.
2.Insert DSUB connecter W1 into the EJ-50U.
3.Insert W2 of EJ-50U into CN4 of this unit.

4.Connect the EJ-50U with a personal computer.
Connect the DSUB connecter on the rear panel and the serial port of a personal
computer with a straight cable.
IMPORTANT: Between the DSUB9 and a personal computer, use a 9-pin RS-232C
straight cable (male-female).

Packet Mode Setting
1.Press the FUNC key. While [F] icon is on, press
the H/L and SQL keys. [TNC] lights up on the
display and the unit enters packet mode.
By the same operation, [TNC] disappears, the
unit exits from packet mode and the display
returns to its normal status.
2.Use the computer keyboard to send designated
commands from your PC to start packet com-
munication.
NOTE:•Parameters for communication with a PC terminal.
Please use PC commands to program the following.
Data Speed (Transfer Rate) : 9600bps
Data Length : 8 bit
Parity Bit : None
Stop Bit : 1 bit
Flow Control : Xon/Xoff
•What is programmed from a PC is stored in memory even after the TNC unit is
removed from the transceiver.
•This TNC unit is not equipped with all the functions an external TNC may have
(Some functions may be limited).
IMPORTANT:•Packet communication is easily affected by the transmission and re-
ception environment especially in the 9600bps packet mode, communi-
cation error may easily occur unless all segments of the S-meter are
displayed.
•While in the packet mode or geolocating communication mode, tones or
codes are not output even if a Tone setting or a DCS setting is programmed.

Special Functions
APRS
Install the optional TNC unit EJ-50U and an external GPS receiver to operate in this mode.
APRS (Automatic Packet/Position Reporting System) is program software registered as a trade-
mark of Bob Bruninga, WB4APR. With this program, you may trace a mobile station on a map
displayed by a computer.
For tracking a mobile station, you may need a PC installed with APRS, this unit (transceiver), and
a TNC (EJ-50U). You may also need a GPS receiver, which captures signals from satellites and lets
you know where you are.
APRS will retransmit NMEA (National Marine Electronics Association) data message received from a GPS
receiver. For detailed information, please see the Internet web page regarding APRS. (www. taps. org.)
NOTE: GPS means Global Positioning System.
APRS Settings
APRS needs TNC unit EJ-50U, a GPS receiver and a PC with APRS software installed. Select an
external GPS receiver compatible with the NMEA format.
Configuration  NMEA: NMEA-0183, 4800bps/Parity Bit none/Data Length 8bit/Stop Bit 1bit
Connecting the GPS
Please refer to the chapter or packet communication for EJ-50U installation and connection
to a PC.
1.Connect a GPS receiver to CN5 connecter inside of this unit using the provided
wiring cable with some modification.
(Modification/connection of the wiring cable to the terminal is as follows)

NOTE:•You may remove the PC after setting is completed. (What has been
programmed is stored in the TNC unit. To change settings, you must
reconnect the computer.)
•Setting the of call sign of your station, communication speed and Bea-
con transmission time interual may be changed by the TNC clone of

the command mode (cmd:).
[Example cmd: HB 1200 or 9600]
4.Register the call sign of your station.
[Example cmd: MY *****]
5.Set the communication speed of the GPS port.
[Example cmd: GB 4800]
6.Set the automatic transmission time interval.
[Example cmd: LOC E 3]
7.When the location data etc. is received from
the GPS receiver, it will be automatically trans-
mitted as programmed.
8.By pressing the FUNC key and then the H/L
key, the TNC will be turned off and transmis-
sion of position data will be stopped.
9.By turning the TNC on again, automatic trans-
mission will resume following the previous set-
tings.
IMPORTANT:•While using APRS software, the header setting for monitoring should be OFF.
(Input:  cmd: LTMH OFF)

Special Functions
TNC Clone
This feature enables setting changes required for APRS function without connecting to a PC.
Please use this feature when a setting change is desired while the APRS function is in operation.
Setting changes are available for the call sign of your station, communication speed and data trans-
mission time separation (Setting is made in setting mode).
1.Press the FUNC key and then press the H/L
key while [F] icon is on (Enter packet mode).
2.Press the CALL key with the FUNC key pressed.
The display will show [TNCLON] and data pro-
grammed in setting mode for the call sign of
your station, the communication speed and data
transmission time separation are transmitted.
3.Upon completion of data transmission, the dis-
play shows [PASS].
Turning the unit off will make it exit the clone
mode and restore normal packet operation.

Entering a frequency directly
Frequencies can be entered directly by pressing the numerical keys of the microphone.
• Range of frequencies to be input
76.000 - 107.995MHz (WFM reception)
144.000 - 145.995MHz
430.000 - 439.995MHz
1.Set the microphone DTMF/REMOTE switch to the REMOTE position.
2.DTMF keys can be used to enter from the 100MHz digit.
(Ex.) When setting 144.20 MHz with the tuning step set to 20kHz.
Enter 1  4  4  2  0
After entering the f ifth digit a slightly longer beep is emitted and the entry is com-
pleted.
3. To cancel an entry before it is completed, press the PTT key or C key.
Entry method depending on tuning step
Depending on the set tuning step, frequency entry may be necessary to the 1 kHz digit. In some
cases entry to the 10 kHz digit is suff icient. For cases in which digit entry is only necessary to the
10 kHz digit some digit keys are not accepted.
The relationship between the tuning step and input method is as follows.
Tuning stepEntry
Final digit selectioncompletion digit
5.0 kHz 1 kHz Completion after input of the 1 kHz digit.
8.33 kHz 1 kHz    10kHz
Depending on the frequency, either the 1kHz digit or 10kHz digit may be entered.
10.0 kHz 10 kHz Completion after input of the 10 kHz digit.
When you input the 10 kHz digit, the 1 kHz digit is set as follows:
12.5 kHz 10 kHz 0···00.0,   1···12.5,   2···25.0,   3···37.5,   4···invalid
