OPERATING THROUGH REPEATERS  
Repeaters are often installed and maintained by radio clubs, sometimes with the cooperation of local businesses involved  
in the communications industry.  
Compared to simplex communication, you can usually  
transmit over much greater distances by using a  
repeater. Repeaters are typically located on mountain  
tops or other elevated locations. They generally operate  
at higher ERP (Effective Radiated Power) than a typical  
station. This combination of elevation and high ERP  
allows communications over considerable distances.

REPEATER ACCESS  
Q Selecting an Offset Frequency  
The offset frequency is the value which the transmit  
frequency will be offset from the receive frequency.  
The default offset frequency on the 144 MHz band  
is 600 kHz for all type versions. The default on the  
430/440 MHz band is 5 MHz.  
Most repeaters use a receive and transmit frequency pair  
with a standard or  
non-standard offset (odd-split). In addition, some  
repeaters must receive a tone from the transceiver in  
order to gain access to the repeater. For details, consult  
your local repeater reference.  
1 Select your desired band (A or B).  
2 Enter Menu mode and access Menu 160.  
Q Selecting an Offset Direction  
The offset direction allows your transmit frequency to  
be higher (+) or lower (–) than the receive frequency.  
1 Select your desired band (A or B).  
2 Press [F], [MHz] to select an offset direction.  
3 Set the appropriate offset frequency value.  
Each time you press [F], [MHz], the offset direction  
changes as follows:  
The selectable range is from 00.00 MHz to 29.95  
MHz, in steps of 50 kHz.  
Simplex operation ° + ° ° Simplex operation  
Note: After changing the offset frequency, the new offset  
frequency will also be used by Automatic Repeater Offset.  
Q Activating the Tone Function  
To turn the Tone function on:  
1 Select your desired band (A or B).  
2 Press [TONE] to turn the Tone function On.  
Each time you press [TONE], the selection changes  
as follows:  
Tone ( ) ° CTCSS (  
Tone ( : default) ° Off (no display).  
<Additionally, when APRS is ON and Voice Alert is  
configured, Voice Alert ON is added to the above  
cycle.>  
) ° DCS (  
) ° Cross  
If you are using a TH-D72E, when operating on  
the 430 MHz band, the offset direction changes as  
follows:  
Simplex operation ° + ° ° = (–7.6 MHz) °  
Simplex operation  
The “ ” icon appears on the display when the tone  
function is On.  
If the offset transmit frequency falls outside the  
allowable range, transmitting is inhibited. Use one of  
the following methods to bring the transmit frequency  
within the band limits:  
Move the receive frequency further inside the band.  
Change the offset direction.  
Note: While using an odd-split memory channel or transmitting,  
you cannot change the offset direction.

TRANSMITTING A 1750 Hz TONE  
AUTOMATIC SIMPLEX CHECKER (ASC)  
Most repeaters in Europe require that a transceiver  
transmit a 1750 Hz tone. On a TH-D72E, simply pressing  
[CALL] will transmit this tone. It is also possible to  
program [1750] on the front panel as a [CALL] key for  
transmitting the 1750 Hz tone.  
While using a repeater, ASC periodically monitors the  
strength of signals you receive directly from the other  
stations. If the station’s signal is strong enough to allow  
direct contact without a repeater, the “ ” icon blinks.  
Press [REV] (1s) to turn the ASC On.  
1 Enter Menu mode and access Menu 162.  
When the ASC is On, the “ ” icon will appear on the display.  
2 Set it to “1750Hz”.  
While direct contact is possible, without the use of a repeater,  
the “ ” icon will begin blinking.  
To exit ASC, press [REV].  
Some repeaters in Europe must receive continuous  
signals for a certain period of time, following a 1750 Hz  
tone. This transceiver is also capable of remaining in the  
transmit mode for 2 seconds after transmitting a 1750 Hz  
tone.  
Note:  
X
X
X

Pressing [PTT] will cause the “ ” icon to stop blinking.  
ASC does not function if you are using simplex operation.  
ASC does not function while scanning.  
Activating ASC while using Reverse will switch the Reverse  
function Off.  
1 Enter Menu mode and access Menu 163.  
X
If you recall a Memory channel or the Call channel, and those  
channels are set up with the Reverse function switched On, the  
ASC will switch Off  
X
X
You cannot use ASC when the built-in TNC is turned On.  
ASC causes received signals to be momentarily intermitted every  
3 seconds.  
2 Set it to “On”.  
Note: While remaining in the transmit mode, the transceiver does not  
continuously transmit a 1750 Hz tone.  
TONE FREQUENCY ID  
This function scans through all tone frequencies to identify  
the incoming tone frequency on a received signal. You  
can use this function to find which tone frequency is  
required by your local repeater.  
REVERSE FUNCTION  
After setting a separate receive and transmit frequency,  
you can exchange these frequencies using the Reverse  
function. This allows you to manually check the strength  
of signals you receive directly from other stations, while  
using a repeater. If the station’s signal is strong, move to  
a simplex frequency to continue the contact and free up  
the repeater.  
1 Press [TONE] to switch the Tone function On.  
The “ ” icon appears on the display.  
2 Press [F], [TONE] (1s) to run the Tone Frequency ID  
scan.  
Scan starts and Scanningblinks on the display.  
Press [REV] to turn the Reverse function On or Off  
When the Reverse function is On, the “ ” icon will appear on  
the display.  
To reverse the scan direction, turn the Tuning  
control clockwise <or press [ ]> (upward scan) or  
counterclockwise <or press [ ]> (downward scan).  
To quit the function, press [ESC ].  
Note:  
When the tone frequency is identified, the identified  
frequency appears on the display and blinks. Press any  
key other than [ OK] while the identified frequency is  
blinking, to resume scanning.  
X
If the transmit frequency is outside the allowable transmit  
frequency range when using Reverse, pressing [PTT] will cause  
an error tone to sound and transmission will be inhibited.  
X
If the receive frequency is outside the receive frequency range  
when using Reverse, an error tone will sound and Reverse will  
not operate.  
X
X
The ARO (Automatic Repeater Offset) will not function when  
Reverse is ON.  
You cannot switch Reverse On or Off while transmitting.  
3 Press [ OK] to program the identified frequency in  
place of the currently set tone frequency.  
The Tone function will remain On. You can press [TONE]  
to switch the Tone function Off.  
Press [ESC ] if you do not want to program the  
identified frequency.

with a non-standard offset. To access those repeaters,  
store two separate frequencies in a memory channel. You  
can then operate on those repeaters without changing the  
offset frequency you stored in the menu.  
2 Set the recall method to “Current band” or “All  
bands”.  
1 Set up a simplex channel by following steps 1 to 6 of  
“STORING SIMPLEX AND STANDARD REPEATER  
FREQUENCIES”, above.  
“Current band” allows you to recall only those memory  
channels that have stored frequencies within the  
current band. “All bands” allows you to recall all  
programmed memory channels.  
When the recalled memory channel is an AM channel,  
you cannot recall on the A band.

CTCSS/ DCS/ CROSS TONE  
CTCSS  
You may sometimes want to hear calls only from specific persons. The Continuous Tone Coded Squelch System  
(CTCSS) allows you to ignore (not hear) unwanted calls from other persons who are using the same frequency. To do  
so, select the same CTCSS tone as selected by the other persons in your group. A CTCSS tone is subaudible and is  
selectable from among 42 tone frequencies.  
DCS  
Digital Coded Squelch (DCS) is another application which allows you to ignore (not hear) unwanted calls. It functions the  
same way as CTCSS. The only differences are the encode/ decode method and the number of selectable codes. For  
DCS, you can select from 104 different codes.  
Note: CTCSS/ DCS does not cause your conversation to be private. It only relieves you from listening to unwanted conversations.  
To cancel CTCSS, press [TONE] until “

Q VOX Gain  
To enjoy the VOX function, take the time to properly  
adjust the VOX Gain level. This level controls the VOX  
circuit to detect the presence or absence of your voice.  
2 Set the TX inhibit to “On” or “Off”.  
There are 2 ways to adjust the VOX Gain.  
“TX Inhibit” appears and an error beep sounds if the  
transceiver tries to transmit while TX Inhibit is ON.  
While the VOX function is ON:  
1 Speak into the headset microphone using your  
normal tone of voice to transmit.  
If the transmission does not begin, you must readjust  
the VOX Gain so that transceiver transmits while you  
are speaking. To readjust the gain, press and hold  
[PTT] then press [ ]/[ ] to select a more sensitive  
gain level.  
SELECTING AN OUTPUT POWER  
While readjusting the gain, you can release [PTT].  
The transceiver will remain in Adjustment Mode for  
approximately 5 seconds.  
It is a good idea to select lower transmit power if  
communications is still reliable. This lowers the risk of  
interfering with others on the band. When operating from  
battery power, you will enjoy more operating time before a  
recharge is necessary.  
2 Adjust the VOX Gain by pressing [ ]/[ ] until  
the transceiver reliably switches to transmission  
mode each time you speak while the transceiver is  
transmitting.  
Press [F], [MENU] to select high (H), low (L), or economic

when the VOX circuitry senses that you have begun  
speaking into the microphone.  
If the transceiver returns to reception mode too quickly  
after you stop speaking, the end of your transmission  
may not be sent. To avoid this, select an appropriate  
delay time that allows your entire transmission to be  
sent, before Transmit mode ends. However, do not  
make the delay overly long.  
When you operate the VOX function, you must use an  
optional Headset; the internal speaker and microphone  
are too close to each other to be used for the VOX  
function.  
1 Enter Menu mode and access Menu 136.  
To turn the VOX function ON:  
1 Enter Menu mode and access Menu 134.  
2 Set the desired delay time to 250, 500 (default),  
750, 1000, 1500, 2000, or 3000 ms.  
2 Set it to “On”.

If you press [CALL] (if 1750 Hz is programmed) to transmit a  
1750 Hz tone, the VOX Delay Time is not reflected.  
If the DCS function is ON, the transceiver remains in Transmit  
mode for the duration set by the VOX Delay Time. It then sends a  
Turn-Off Code to close the receiving party’s squelch.

GPS (GLOBAL POSITIONING SYSTEM)  
What is GPS?  
GPS, standing for Global Positioning System, is becoming common nowadays. Following is a brief introduction.  
The American Defense Department developed GPS originally for military operations. The system is available for use by  
the general public. For example, anybody can use GPS in association with modern vehicle navigation systems. Position  
precision for public use is approximately 15 m.  
Moreover, precision can be improved when a vehicle is used for navigation and aboard ships through use of map  
matching technology and differential GPS techniques.  
A total of 24 or more GPS satellites are at a high-level altitude of approximately 20,000 km on six circular tracks with an  
orbital radius of approximately 26,000 km. Therefore, there are four or more satellites located in each orbital track. For  
civilian use, the RF carrier frequency of the satellites is 1575.42 MHz. Spread spectrum (SS) technology is used over a  
bandwidth of 2.046 MHz to prevent interference among all the satellite signals on a common carrier frequency.  
Datum (Geodetic Survey System)  
The GPS receiver receives the radio signals transmitted from the GPS satellites. The receiver measures the time duration  
between when the signal leaves the satellite and when the signal arrives at the GPS receiver. Knowing this time allows  
calculation of the distance that the signal traveled from that particular satellite. By receiving multiple signals from different  
satellites and doing this distance calculation multiple times, the intersection of the spherical surfaces that represent the  
respective radius distances to the various satellites will determine a single point.  
The precision of the determination of the intersecting point relies on the satellites and the data collected.  
Position Determination Principle  
The latitude and longitude information required by the GPS receiver does not allow for accurate representation of the  
unevenness of the Earth’s surface. For use with GPS, the current standard that defines the precise shape of the Earth is  
called WGS-84. By using this standard in conjunction with mapping standards for each country, accurate position plotting  
on a map can be done.  
GPS and APRS Position Format  
Although position can be described in many different formats, such as degrees, degrees and minutes, and degrees,  
minutes and seconds, the GPS system and APRS have standardized on the degrees and decimal minutes format.  
Just like it is important to use proper international phonetics when spelling on the air, it is important in APRS as in any  
communications system to have a default standard for position. All operators should be trained to use the DDD MM.mm  
format by default in voice communications just like in data formats. Using these standards on the air will prevent  
communications errors, confusion, repeats, and conversions.

The built-in TNC could be automatically reinitiated when  
its malfunction is detected; this does not designate that the  
transceiver is defective.  
The internal TNC is a 2-chip type that does not have an SRAM  
backup. Therefore, the settings made using commands in Packet  
mode (such as MYCALL) will be reset when the power is switched  
Off and then back On.  
To distinguish your various stations or nodes, you can have up  
to 15 Secondary Station Identifiers (SSIDs); ex. W6DJY-1 to  
W6DJY-15. You always have to put a dash between your call sign  
and SSID number.  
Packet operation, easily affected by transmit and receive  
conditions, requires a full-scale S-meter reading for reliable  
communication. When the S-meter reads less than maximum  
during 9600 bps operation, communication errors are frequent.

APRS®  
APRS DATA COMMUNICATION (APRS BEACON)  
X This function uses the APRS format for data communications including your station position, messages, etc..  
X When data is received from another station, the direction of the received station (from your station’s perspective), their  
distance, and their grid square locator is displayed. Any comments sent by the other station are also displayed.  
X Meteorological data obtained from a connected Weather Station can be transmitted.  
X APRS (Automatic Packet Reporting System) is a worldwide system introduced by Bob Bruninga, WB4APR .  
< APRS® is a software program and registered trademark of Bob Bruninga, WB4APR.>  
NAVITRA DATA COMMUNICATION (NAVITRA BEACON)  
X The Navitra system was introduced by Kenwood in the 1990’s, for use within Japan.  
CALL SIGN AND BEACON TYPE SETTINGS  
X When an APRS/NAVITRA beacon is created, set the call sign and beacon type (APRS/NAVITRA) (Menu 301).  
X SSID (Secondary Station IDentifiers) can be added to the end of your call sign (for example, W6DJY will become  
W6DJY– 11). SSIDs can range from “None, – 1” to “– 15”, so that each call sign can have up to 16 settings.  
DIGIPEAT  
X The term digipeat means that the beacon packet data is relayed. When a digipeater (relay station) receives a packet  
(beacon), it saves it to memory. When the reception ends, the data is re-transmitted. Using digipeat, it is possible to  
send beacons long distances.  
X In order to perform a digipeat, you must set up a packet path (relay path) (Menu 3H0). For relay modes, you can  
specify a direct call sign or you can use “WIDE1-1” or “WIDE1-1, WIDE2-1”, specifying a common alias and hops  
number. Set the transceiver’s packet path according to the digipeater settings.  
X Digipeat is very useful in reaching other stations when you have a weak signal. However, you need to set up the total  
hops numbers and beacon transmissions moderately to prevent channel congestion.  
Fill-in type

RECEIVING APRS DATA  
The APRS programs for PCs have entry fields for a position  
comment and status text. The data entered to these two fields are  
transmitted as separate packets. This transceiver, however, includes  
both of a position comment and status text in one packet to transmit.  
Each time a new APRS packet is received, the frequency  
display is interrupted to show information as below:

STORING STATUS TEXT  
QSY FUNCTION  
Status text is another comment to transmit with position  
data. Unlike a position comment, you can make any  
desired comment using a maximum of 42 alphanumeric  
characters. This transceiver has 5 memory channels for  
preprogramming.  
The QSY function uses AFRS (Automatic Frequency  
Reporting System) to report a frequency on which voice  
communications can be established. A station using  
the QSY function embeds the frequency information in a  
position beacon transmission. A receiving station of this  
information can change frequency, or QSY, over to the  
reported voice frequency to begin voice communication by  
the select of [Tune].  
1 Access Menu 3A0.  
Transmitting QSY Information  
A properly configured functioning TM-D72 QSY station  
can automatically embed the voice frequency from the  
non-data band to the beginning of status text. This is  
the mechanism used for automatically transmitting the  
frequency information.  
2 Select a status text number.  
Press [MHz] to mark the currently used status text with ( ).  
3 Select the frequency on which to transmit the status  
text when the APRS beacon is transmitted. You can  
select “Off” or “1/1” ~ “1/8” (APRS only).  
The format of the transmitted frequency is FFF.FFF MHz.  
So, for example, if at the time of a beacon transmission,  
the non-data band has a frequency of 446.100 MHz  
selected, then the frequency of “446.100MHz” gets  
embedded to the beginning of the status text. If you  
configure in any of Statuses 1 through 4 the frequency  
of “446.100MHz” at the beginning of the status text  
messages, then this fixed frequency will be transmitted  
as QSY information along with the beacon transmission.  
In addition to frequencies, there are fields where you  
can send other settings such as Wide/Narrow, Tone/  
CTCSS/DCS, Shift (+/-), and Offset frequency simply by  
-leaving one space between each value. Therefore, other  
information besides just a frequency can be sent.  
1/X means the status text will be transmitted X number of  
times.  
4 Enter your status text.  
QSY Information Format:  
(Insert one space after the frequency before entering  
Wide/Narrow, Tone/CTCSS/DCS and Shift/Offset.)  
“T079”: An upper case “T” indicates Wide. Tone frequency of  
79.7 Hz. (Encoding)  
“t079”: A lower case “t” indicates Narrow. Tone frequency of  
79.7 Hz. (Encoding)  
“tOFF”: A lower case “t” indicates Narrow. Tone = OFF  
(Without any tone Encoding or Decoding.)  
“C079”: An upper case “C” indicates Wide. CTCSS  
frequency of 79.7 Hz. (Encoding/ Decoding)  
“c079”: A lower case “c” indicates Narrow. CTCSS frequency  
of 79.7 Hz. (Encoding/ Decoding)  
“D023”: An upper case “D” indicates Wide. DCS code of 023.

Q Connecting TH-D72 with the HF Transceiver  
DX PACKETCLUSTERS MONITOR  
In order to connect TH-D72 to the HF transceiver, you  
need to prepare three cables by yourself.  
DX PacketClusters are networks which consist of nodes  
and stations who are interested in DXing and contesting.  
If one station finds a DX station on the air, they will  
send a notice to their node. This node then passes the  
information to its local stations through another node.  
The DX PacketCluster monitor function receives the  
packet data of the DX cluster and displays the contents.  
This transceiver can retain the latest information on up  
to 10 DX stations, but the memory will be cleared when  
the transceiver power supply is turned Off. If you have  
a TS-590S, TS-480HX/SAT, TS-2000/X, TS-570S/D, or  
TS-870S HF transceiver, you can connect the TH-D72  
to the HF transceiver to use the DX PacketCluster Tune  
function. You can use this function to monitor the latest  
DX information in your area, be it cannot be used to send  
DX information to a node.  
The COM terminal on this transceiver accepts a 2.5  
mm (1/10") 3-conductor plug. If necessary, use the  
cable (service part: E30-3400-XX) to modify the cable  
end of RS-232-C connector.

SKY COMMAND SYSTEM II  
The SKY COMMAND SYSTEM II allows remote control of a TS-2000, TS-2000X, TS-B2000, TS-480HX, TS-480SAT, TS-  
590S, TS-570D, TS-570S, or TS-870S HF transceiver.  
You will use one transceiver as a control station called “Commander”. The transceiver connected with the HF transceiver  
is called “Transporter”. It will function as an interface between the Commander and the HF transceiver. This system  
allows you, for example, to watch for and hunt DX while washing your car, or to operate the HF transceiver while relaxing  
in your car, living room, or patio, instead of in your shack.  
The Commander and Transporter transfer audio and commands as below:

CONNECTING THE TRANSPORTER WITH THE HF TRANSCEIVER  
In order to connect TH-D72 to the HF transceiver, you need to prepare three cables by yourself. The COM terminal on  
this transceiver accepts a 2.5 mm (1/10") 3-conductor plug. If necessary, use the cable (service part: E30-3400-XX) to  
modify the cable end of RS-232-C connector.

Operation of Sky Command System II may not been permitted in certain countries. Check your local laws before operating.  
Switch OFF both the Transporter and HF transceiver before making the connection.  
The Transporter automatically transmits its call sign in Morse at regular intervals because of legal requirements; therefore, transmit side tone  
must be output from the HF transceiver.

When the Transporter is too close to the HF transceiver, unwanted feedback may cause malfunction.  
Do not share a regulated power supply between the Transporter and the HF transceiver. Unwanted feedback may cause malfunction.

PROGRAMMING CALL SIGNS  
CONTROL OPERATION  
The built-in TNCs of the Commander and Transporter  
communicate each other when you send a control  
command from the Commander. So you must program  
different call signs (9 digits max.) on these transceivers as  
the IDs of the TNCs.  
When in the Sky Command mode, the Microphone keys  
of the Commander will function as below. First switch  
ON the HF transceiver and press Microphone [0] on the
