• Select the level at which the background noise is just eliminated when no signal is present.
• The higher the level selected, the stronger the signals must be to receive.

3 Press [OK] to complete the setting.

TRANSMITTING

1 To transmit, press and hold the PTT switch and speak into the microphone in a normal tone of voice.

• Indicator A or B lights red depending on which band you have selected.
• The battery meter appears to show the current relative battery charge.

• Speaking too close to the microphone, or too loudly, may increase distortion and reduce intelligibility of your signal at the receiving station.

2 When you finish speaking, release the PTT switch.

Time-Out Timer: Holding down the PTT switch for more than 10 minutes causes the transceiver to generate a beep and stop transmitting. Release, then press the PTT switch to resume transmitting. You cannot switch this function OFF.

CAUTION

The recommended duty cycle is 1 minute of transmission and 3 minutes of reception. Extended transmissions in the high power mode may cause the back of the transceiver to get hot.
Transmitting with the supplied antenna near other electronic equipment can interfere with that equipment. Also, transmitting near a poorly regulated power supply, that is not recommended by KENWOOD, may cause the power supply to output an extremely high voltage. This voltage could damage both your transceiver and any other equipment connected to the power supply.

Note: If input voltage exceeds approximately 18 V while using an external power source, warning beeps sound and a warning message appears.

Selecting Output Power

Selecting lower transmit power is a wise method to reduce battery consumption, if communication is still reliable. You can program a different power for band A and B.

Repeaters, which are often installed and maintained by radio clubs, are usually located on mountain tops or other elevated locations. Generally they operate at higher ERP (Effective Radiated Power) than a typical station. This combination of elevation and high ERP allows communications over much greater distances than communications without using repeaters.

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 to allow it to access. For details, consult your local repeater reference.

Offset Programming Flow

Select a band.
Select a receive frequency.
3 Select an offset direction.
4 Select an offset frequency. (Only when programming odd-split repeater frequencies)
Activate the Tone function. (If necessary)
Select a tone frequency. (If necessary)

If you store the above data in a memory channel, you need not reprogram every time. See "MEMORY CHANNELS" {page 26}.

PROGRAMMING OFFSET

First select band A or B by pressing [A/B]. Then, if necessary, press [F], [A/B] to recall the sub-band.

Selecting Offset Direction

Select whether the transmit frequency will be higher (+) or lower (-) than the receive frequency.

Press [F], [MHz] to switch the offset direction.

• "+" or "-" appears to indicate which offset direction is selected.

• To program -7.6 MHz offset on the TH-D7E (UHF only), repeatedly press [F], [MHz] until "==" appears.

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.

Selecting Offset Frequency

To access a repeater which requires an odd-split frequency pair, change the offset frequency from the default which is used by most repeaters. The default offset frequency on the VHF band is 600kHz no matter which market version; the default on the UHF band is 5 MHz (TH-D7A) or 1.6 MHz (TH-D7E).

1 Press [F], [5] to select "F-5 (OFFSET)".

2 Press [UP]/[DWN] to select the appropriate offset frequency.
- The selectable range is from 0.00 MHz to 29.95 MHz in steps of 50 kHz.
3 Press [OK] to complete the setting.

TH-D7E Only: If you have selected “ ” for the offset direction, you cannot change the default (7.6 MHz).

Note: After changing the offset frequency, the new offset frequency will also be used by Automatic Repeater Offset.

Activating Tone Function

Press [F], [1] to switch the Tone function ON (or OFF).
- "T" appears when the Tone function is ON.

Note: You cannot use the Tone and CTCSS functions simultaneously. Switching the Tone function ON after activating the CTCSS deactivates the CTCSS.

TH-D7E Only: When you access repeaters that require 1750 Hz tones, you need not activate the Tone function. No matter which selection you make here, simply pressing [CALL] without pressing the PTT switch causes the transceiver to transmit a 1750 Hz tone.

Selecting a Tone Frequency

1 Press [F], [2] to select "F-2 (TONE FREQ)".

2 Press [UP]/[DWN] to select the appropriate tone frequency.

3 Press [OK] to complete the setting.

MEMORY CHANNELS

In memory channels, you can store frequencies and related data that you often use. Then you need not reprogram those data every time. You can quickly recall a programmed channel by simple operation. A total of 200 memory channels are available for bands A and B.

7

SIMPLEX & REPEATER OR ODD-SPLIT MEMORY CHANNEL?

You can use each memory channel as a simplex & repeater channel or 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 channel allows:

Simplex frequency operation
- Repeater operation with a standard offset (If an offset direction is stored)

Odd-split channel allows:
- Repeater operation with a non-standard offset

Note:

Not only can you store data in memory channels, but you can also overwrite existing data with new data.
If you have recalled a memory channel on the non-current band (A or B), you cannot select the same channel on the current band to program data.

The data listed below can be stored in each memory channel:

Parameter	Simplex & Repeater	Odd-split
Receive frequency	Yes	Yes
Transmit frequency		Yes
Tone frequency	Yes	Yes
Tone ON	Yes	Yes
CTCSS frequency	Yes	Yes
CTCSS ON	Yes	Yes

Packet is a unit of data transmitted as a whole from one computer to another on a network. Packets can be transmitted on radio waves as well as on communications lines. Besides a transceiver and a computer, all you need is a terminal node controller (TNC). A TNC converts packets to audio tones and vice versa as one of its tasks. This transceiver has a built-in TNC.

A variety of packet applications developed by hams include packet bulletin board systems (PBBSs). PBBSs are created and maintained by volunteers called a System Operator (SysOp). You may access one of your local PBBSs to send e-mail, download a file, or obtain various useful information. Thousands of PBBSs, which have formed a worldwide network, relay e-mail to its intended destination around the world. First find out the call signs and frequencies used by your local PBBSs. Reference material for starting packet operation should be available at any store that handles Amateur Radio equipment.

Note:

Not all functions available via conventional TNCs are supported by the TNC built in this transceiver.
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.
This transceiver is incapable of functioning as a digipeater.
"IND STA"indicates packets to be transmitted still remain in the buffer.

TH-D7E Only: When using the VHF band to transmit packets, do not select the narrow transmit deviation {page 51}.

OPERATING TNC

This 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 "cmd:" 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 "TNC COMMANDS LIST" on page 99.

PREPARATION FLOW

The following steps should guide you to a good start of packet operation. The shaded steps indicate operations on your personal computer. First connect the transceiver to the personal computer {page 53}.

Note: You may switch Battery Saver OFF {page 49} to prevent the initial portion of a received packet from being missed.

Install an appropriate communications program on the personal computer.
- A variety of freeware or shareware programs can be obtained in various ways. Consult your reference material or other "packeteers".

2 Initiate the communications program and set the following parameters on the personal computer:

• Transfer rate (TNC < - Computer): 9600 bps

• First you may want to monitor packets which are transmitted among other stations. When packets are received, text appears and the computer screen scrolls.

To connect with the target station, type CONNECT (or C) then its call sign and press [Enter] or [Return].

• When a linkage is established, a message which informs you of it appears on the computer screen; on the transceiver display, “MN6_CN” appears.
• If packets from other stations keep your squelch open, adjust the squelch level in advance. The TNC cannot transmit in such a situation.

10 Send appropriate commands and, if necessary, messages to the target station via the TNC.

SELECTING DATA BAND

This transceiver is capable of receiving packet data on one band (data band) while receiving audio on another band. Select band A or B as the data band for receiving or transmitting packets. "B" indicates the current data band; the default is band A.

Access Menu 1-4-1 (DATA BAND) and select band A or B.

You can also select the method for inhibiting the built-in TNC from transmitting. Access Menu 1-4-2 (DCD SENSE) and select one of the two methods.

D BAND ONLY:

The TNC does not transmit when signals are present on the data band.

BOTH BANDS:

The TNC does not transmit when signals are present on the data band or another band.

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).

AUTOMATIC PACKET/ POSITION REPORTING SYSTEM

The Automatic Packet/ Position Reporting System (APRS) 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:

Station icon	Weather reporting1
Position comment	Status text
Moving speed2	Moving direction2

1 Receive only
2 Can 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:

Turn OFF the transceiver power before making the connections.
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}.

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 declares his (or her) digipeater to be a "wide" type or "relay" type. Generally a wide-type digipeater transmits packets over much greater distances than a relay-type one.

The APRS supports various methods for specifying a packet path. Some of those methods are described on the next page. This transceiver allows you to edit a path using a maximum of 32 alphanumeric characters. The default is "RELAY,WIDE" that is one of the common settings. A comma must be put between each parameter.

Note: This transceiver is incapable of functioning as a digipeater.

1 Press [MENU] to enter Menu mode.
2 Press [2], [8] to select "2-8 (PACKET PATH)".

• The display for entering characters appears; the first digit blinks.

3 Press [UP]/[DWN] to select a character.

• You can enter 0 to 9, A to Z, , (comma), and -.

4 Press [OK].

• The cursor moves to the next digit.

5 Repeat steps 3 and 4 to enter up to 32 digits.

• Pressing [OK] after selecting the 32nd digit completes the programming.
• To complete programming after entering less than 32 digits, press [OK] twice.
  Each press of [ESC] causes the cursor to move backward.
• Pressing [A/B] deletes the digit at which the cursor is blinking.

6 Press [MENU] to exit Menu mode.

You can also use the keypad to enter alphanumeric characters in step 3. For example, each press of [TNC] switches entry as A, B, C, then 2. Press [ENT] to switch between , and - .

Let us describe four basic methods for editing a packet path.

Method 1 (Specific path):

Program the call signs of one or more digipeaters in the sequence of transfer relay; ex. "KD6ZZV,KF6RJZ".

Method 2 (Generic path):

Program "RELAY" and/or "WIDE"; ex. "RELAY,WIDE". In this example, APRS data is transferred to any relay-type digipeater near your position first, then to any wide-type digipeater. You can also program more than one "WIDE". If you enter "WIDE,WIDE" for example, APRS data will be transferred to any wide-type near your position first, then to another wide-type. This method relieves you from specifying the call signs of digipeaters.

Method 3 (WIDEN-N path):

Program "WIDEN-N", where both Ns indicate the number of wide-type digipeaters to be used for relay. If you enter "WIDE3-3" for example, APRS data will be relayed by three digipeaters in any direction.

Note: This method is supported only by advanced APRS networks.

Method 4 (SSID path):

Program a single number 1 to 15. You can easily specify the number of digipeaters that will be used for relay. You can also specify which directions of digipeaters relative to your position will be used. See the table.

Note: This method is supported only by advanced APRS networks.

Parameter	Number of digipeaters	Direction
1	1	All
2	2	All
3	3	All
4	4	All
5	5	All
6	6	All
7	7	All
8	2 (or more)1	North
9	2 (or more)1	South
10	2 (or more)1	East
11	2 (or more)1	West
12	Many2	North
13	Many2	South
14	Many2	East
15	Many2	West

¹ The first digipeater which receives your APRS data specifies the entire route to the destination before forwarding; often 2 digipeaters are used in total.
2 The digipeater which receives your APRS data specifies the call sign of the next digipeater before forwarding. This is repeated until your APRS data reaches the destination.

- For the method, refer to the instruction manual for the mobile transceiver. If not described, consult your authorized KENWOOD dealer, customer service, or service center.

CONTROL OPERATION

When in Remote Control mode, the keys of the handy transceiver will function as below. Each time you press the desired key, the handy transceiver will automatically enter transmit mode and send the corresponding command to the mobile transceiver.

TM-V7A: REV ON/ OFF
Switches Cross-band Repeater ON/ OFF if the mobile transceiver has the function.

To change the transmit/ receive frequency:

$$ \begin{array}{l} \left([ \mathrm {V F O} ] \Rightarrow [ \mathrm {E N T} ] \Rightarrow [ 0 ] \sim [ 9 ] \text {(e n t e r t h e n e c e s s a r y d i g i t s)} \right. \ \Rightarrow [ \mathrm {E N T} ]) \text {o r} \left([ \mathrm {V F O} ] \Rightarrow [ \mathrm {U P} ] / [ \mathrm {D W N} ]\right) \end{array} $$

To recall a memory channel:

$$ \begin{array}{l} \left([ M R ] \Rightarrow [ E N T ] \Rightarrow [ 0 ] \sim [ 9 ] (e n t e r t h e n e c e n s a r y d i g i t s) \Rightarrow \right. \ \left[ E N T ]\right) o r \left(\left[ M R ] \Rightarrow [ U P ] / [ D W N ]\right) \right. \end{array} $$

To change the tone (or CTCSS) frequency:

$$ \begin{array}{l} \text {(T O N E S E L ]} \Rightarrow [ 0 ] \sim [ 9 ] \text {(e n t e r 2 d i g i t s ; e x . [ 0 ] , [ 5 ])} \Rightarrow \ \text {[ T O N E S E L ])} \end{array} $$

• Use Nos. 01 to 38 shown in the table in page 22.
• Your mobile transceiver may require you to first activate the Tone or CTCSS function. It may also allow you to program a separate tone and CTCSS frequency. Check the instruction manual for the mobile transceiver.

The Sky Command II allows remote control of a TS-570D, TS-570S, or TS-870S HF transceiver. This system requires two TH-D7As and the optional cables which connect one TH-D7A to the HF transceiver. You will use one TH-D7A as both a remote control and speaker microphone. This TH-D7A is called "Commander". The TH-D7 connected with the HF transceiver is called "Transporter". It will function as an interface between the Commander and the HF transceiver. The Sky Command System allows you, for example, to watch for and hunt DX while working around the house, or to operate the HF transceiver while relaxing in the living room or patio, instead of in the shack.

Both the Commander and Transporter use Full Duplex function to transfer audio and commands as below:

CONNECTING THE TRANSPORTER WITH THE HF TRANSCEIVER

You can use the optional cables (PG-4R) to connect the Transporter with the HF transceiver. For these cables, contact your authorized KENWOOD dealer.

Note:

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 the legal requirement; therefore, transmit sidetone must be output from the HF transceiver. On TS-570D or TS-570S, do not select "OFF" in Menu 21. On TS-870S, use the MONI control to adjust the volume of sidetone.
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.

You need not worry about which end goes to which side

HF transceiver

COM connector

EXT SP jack

MIC connector

You may install appropriate noise filters at the shown positions to prevent unwanted feedback from causing malfunction.

PREPARATION FLOW

The following steps should guide you to a good start of Sky Command operation. First connect the Transporter to the HF transceiver {page 84}.

1 On the Commander and Transporter Select the same VHF and UHF frequencies.
On the Commander Access Menu 4-1 to program a call sign (9 digits max.) for the Commander {page 86}.

• You may enter your exact call sign; ex. WD6BQD.

On the Commander Access Menu 4-2 to program a call sign (9 digits max.) for the Transporter {page 86}.
- This call sign must be different from the one for the Commander. So you may add SSID characters; ex. WD6BQD-1.

On the Transporter Access Menu 4-1 to program the same call sign as you

entered in step 2 {page 86}.
On the Transporter Access Menu 4-2 to program the same call sign as you

entered in step 3 {page 86}.

ECHO	E	ON	ON/ OFF	When ON, causes the TNC to echo received characters to the computer.
FIRMRNR	FIR	OFF	ON/ OFF	The other station sends a notice (packet) to you if it is not ready to receive data. When ON, receiving such a notice causes the TNC to suspend transmission until it receives a “ready” notice.
FLOW	F	ON	ON/ OFF	When ON, starting key entry causes the computer to stop displaying received packets.
FRACK	FR	3	0 ~ 250	Specifies the interval from one transmission until retry of transmission. The unit of the parameter is 1 second.
GBAUD	GB	4800	4800/ 9600	Selects 4800 or 9600 bps as the transfer rate between the TNC and the GPS receiver.
GPSSEND	GPSS	—	0 ~ 159 characters	Specifies the content of data to be output to the GPS receiver; this data is used to program the default settings on the receiver. The output data is not stored in memory.
GPTEXT	GPST	PNTS	0 ~ 6 characters	Specifies the type of a message to be determined by LTEXT.
HBAUD	HB	1200	1200/ 9600	Selects 1200 or 9600 bps as the transfer rate between packet stations.
LOCATION	LOC	EVERY 0	EVERY/ AFTER n (n = 0 ~ 250)	If set to EVERY, sends GPS data at intervals of the specified period (n). If set to AFTER, sends GPS data only once after the specified period (n). The unit of n is 10 seconds.
LPATH	LPA	GPS	Call1 (VIA call2, call3, ... call9)	Specifies call signs to send GPS data. Call1 is the call sign of the destination. Call2 to call9 are call signs of stations to be digipeated through.
LTEXT	LT	—	0 ~ 159 characters	Specifies the content of a message to be included in GPS data.
LTMON	LTM	0	0 ~ 250	Specifies the interval for displaying a message determined by LTEXT on the screen; a message appears like a received beacon packet. The unit of the parameter is 1 second.
MCOM	MCOM	OFF	ON/ OFF	When ON, causes the TNC to also monitor control packets. When OFF, causes it to monitor only information packets.
MCON	MC	OFF	ON/ OFF	When ON, causes the TNC to monitor other stations while in connection with the target station.
MONITOR	M	ON	ON/ OFF	When ON, causes the TNC to monitor packets.
MRPT	MR	ON	ON/ OFF	When ON, causes the TNC to display the entire digipeat list for monitored packets.
MYCALL	MY	NOCALL	6 characters + SSID	Specifies your call sign.
PACLEN	P	128	0 ~ 255	Specifies the maximum length of the data portion of a packet.
PACTIME	PACT	AFTER 10	EVERY/ AFTER n (n = 0 ~ 250)	If set to EVERY, sends a packet at intervals of the specified period (n). If set to AFTER, sends a packet only once after the specified period (n). The unit of n is 100 milliseconds.
PERSIST	PE	128	0 ~ 255	Specifies a parameter to calculate probability for the PERSIST/SLOTTIME method.
PPERSIST	PP	ON	ON/ OFF	Causes the TNC to use the PERSIST/SLOTTIME method when ON, or the DWAIT method when OFF.
RESET	RESET	—	—	Restores the default status for all the commands.
RESPTIME	RES	5	0 ~ 250	Specifies the acknowledgment packet transmission delay. The unit of the parameter is 100 milliseconds.
RESTART	RESTART	—	—	Causes the TNC to function as if it is switched OFF then ON.
RETRY	RE	10	0 ~ 15	Specifies the number of transmission retries. If packets are not correctly accepted while in connection, a connect request is sent again after the specified number of retries.
SENDPAC	SE	0D	0 ~ $7F	Specifies a character which forces a packet to be sent.
SLOTTIME	SL	3	0 ~ 250	Specifies the period of random number generation intervals for the PERSIST/SLOTTIME method. The unit of the parameter is 10 milliseconds.
TRACE	TRAC	OFF	ON/ OFF	When ON, causes the TNC to display all received packets in their entirety.
TRIES	TRI	0	0 ~ 15	Specifies the number of transmission retries programmed in the retry counter.
TXDELAY	TX	50	0 ~ 120	Specifies the time delay between PTT ON and start of transmission. The unit of the parameter is 10 milliseconds.
UNPROTO	U	CQ	Call1 (VIA call2, call3, ... call9)	Specifies call signs to send a packet in Unprotocol mode. Call1 is the call sign of the destination. Call2 to call9 are call signs of stations to be digipeated through.
XFLOW	X	ON	ON/ OFF	Causes the TNC to perform software flow control when ON, or hardware flow control when OFF.
