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.

TX: 144.725 MHz
TX tone: 88.5 Hz
RX: 145.325 MHz

TX: 144.725 MHz
TX tone: 88.5 Hz
RX: 145.325 MHz

REPEATER ACCESS

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.

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.

• Each time you press [F], [MHz], the offset direction
changes as follows:

Simplex operation

• If you are using a TH-D72E, when operating on
the 430 MHz band, the offset direction changes as
follows:

Simplex operation
Simplex operation

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.

° + ° – ° Simplex operation

° + ° – ° = (–7.6 MHz) °

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.

1 Select your desired band (A or B).

2 Enter Menu mode and access Menu 160.

3 Set the appropriate offset frequency value.

• The selectable range is from 00.00 MHz to 29.95
MHz, in steps of 50 kHz.

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:

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.

1 Enter Menu mode and access Menu 162.

2 Set it to “1750Hz”.

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.

1 Enter Menu mode and access Menu 163.

2 Set it to “On”.

Note: While remaining in the transmit mode, the transceiver does not

continuously transmit a 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.

• When the ASC is On, the “ ” icon will appear on the display.

• While direct contact is possible, without the use of a repeater,
the “

” icon will begin blinking.

• To exit ASC, press

Note:

TONE FREQUENCY ID

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.

Press [REV] to turn the Reverse function On or Off

• When the Reverse function is On, the “ ” icon will appear on
the display.

Note:

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 The ARO (Automatic Repeater Offset) will not function when

Reverse is ON.

X You cannot switch Reverse On or Off while transmitting.

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.

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 “Scanning” blinks on the display.

MEMORY CHANNELS

In Memory channels, you can store frequencies and related data that you often use. Then you need not reprogram the
data every time. You can quickly recall a programmed channel by simple operation. A total of 1000 Memory channels
are available for bands A and B.

SIMPLEX & REPEATER OR ODD-SPLIT MEMORY
CHANNEL?

You can use each memory channel as a simplex &
repeater channel or as an odd-split channel. Store only
one frequency to use as a simplex & repeater channel or
two separate frequencies to use as an odd-split channel.
Select either application for each channel depending on
the operations you have in mind.

Simplex & repeater channels allow:

• Simplex frequency operation

• Repeater operation with a standard offset (if an offset
direction is stored)

Odd-split channels allow:

• Repeater operation with a non-standard offset

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

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.

PACKET OPERATION

Connect this transceiver to your personal computer via a Terminal Node Controller (TNC). You can send messages
or commands to far away stations, obtain a variety of information via your local bulletin boards, or enjoy other Packet
applications. Reference material for starting Packet operation should be available at any store that handles Amateur
Radio equipment.

Note: When the distance between the radio antenna and your personal computer is too close, interference may occur.

PACKET MODE

This transceiver has a built-in TNC which conforms to the
AX.25 protocol. This protocol is used for communications
between TNCs.

For the commands supported by the built-in TNC, see
“TNC COMMANDS LIST”.

Press [TNC] 2 times to enter PACKET mode.

The following indicators appear on the transceiver display
to show the current TNC status:

Indicator Status

PACKET The TNC is in Packet mode.

STA Packets to be transmitted still remain in the buffer.

CON The TNC is in connection with the target station.

12 1200 bps transfer rate selected

9600 bps transfer rate selected

96

(To set it to 9600bps, use the HB 9600 (or HBAUD

9600) TNC command. This cannot be changed
through the TH-D72 menu.)

DATA BAND

Select how data will be transmitted and received on your
transceiver.

1 Enter Menu mode and access Menu 197.

2 Set the data band to “A-Band” (A band receives and

transmits), “B-Band” (B band receives and transmits),
“A: TX B:RX” (A band transmits (

) and B band
receives ( )), or “A: RX B:TX” (A band receives ( )
and B band transmits ( )).

FULL DUPLEX

This transceiver is also capable of simultaneously
transmitting and receiving signals. So, it is possible to
transmit audio on the current band while receiving packet
data on another band (data band).

1 Set the operation band to Band B.

2 Press [F], [DUP] to enter Full Duplex mode.

• “DUP” appears.

Note:

X Not all functions available via conventional TNC’s are supported

by the TNC built in this transceiver.

X The built-in TNC could be automatically reinitiated when

its malfunction is detected; this does not designate that the
transceiver is defective.

X 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.

X 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.

X 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.

To exit Full Duplex mode, press [F], [DUP] again.

Note:

X When the operating band is Band A, you cannot change to Full

Duplex mode.

X When in single band mode, and Band A/B is set to VHF/VHF or

UHF/UHF, you cannot change to Full Duplex mode.

X When using the Full Duplex function, connect an earphone to the

SP jack. Using an earphone will prevent feedback that can cause
the transceiver to emit a howling sound.

ATTENTION: Use only after verifying that there is no reception
disruption during communications.

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.

Refer to the website for SSID: http://aprs.org/aprs11/SSIDs.txt (currently September 2010)

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.

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].

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.

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.

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.
(Encoding/ Decoding)

• “d023”: A lower case “d” indicates Narrow. DCS code of 023.
(Encoding/ Decoding)

• “+” : Plus Shift (A default offset frequency is applied.)

• “-” : Minus Shift (A default offset frequency is applied.)

• “+500” : Plus Shift, 5MHz Offset (“+5000kHz” is also
available)

• “-060”: Minus Shift, 600kHz Offset (“-0600kHz” is also
available)

The value of the Offset shall be a 3-digit number. (x

DX PACKETCLUSTERS MONITOR

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.

Q Connecting TH-D72 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.

SKY COMMAND SYSTEM II

The SKY COMMAND SYSTEM II allows remote control of a TS-2000, TS-2000X, TS-B2000, TS-480HX, TS-480SAT, TS­590S, 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.
