- 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.

Press [F], [MENU] to select high (default), low, or economic low power (lowest).

OPERATING THROUGH REPEATERS

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

① Select a band.
② Select a receive frequency.
③ Select an offset direction.
4 Select an offset frequency. (Only when programming odd-split repeater frequencies)
⑤ Activate the Tone function. (If necessary)
⑥ 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 600 kHz no matter which market version; the default on the UHF band is 5 MHz (TH-D7A) or 1.6 MHz (TH-D7E).

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.

SELECTING SCAN RESUME METHOD

The transceiver stops scanning at a frequency (or memory channel) on which a signal is detected. It then continues scanning according to which resume mode you select. You can choose one of the following modes. The default is Time-operated mode.

• Time-Operated mode

The transceiver remains on a busy frequency (or memory channel) for approximately 5 seconds, and then continues to scan even if the signal is still present.

• Carrier-Operated mode

The transceiver remains on a busy frequency (or memory channel) until the signal drops out. There is a 2 second delay between signal drop-out and scan resumption.

- Seek mode

The transceiver remains on a busy frequency (or memory channel) even after the signal drops out and does not automatically resume scanning.

Note: To temporarily stop scanning and monitor weak signals, press and hold [MONI]. Release the key to resume scanning.

Note: When using the VHF band to transmit packets, do not switch the function ON.

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.
◆ “TNC 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}.

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 "BEAT SHIFT". Press [UP]/[DWN] to select "UPPER". Press [OK] to complete the setting. The default is "NORMAL".

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
    • Data length: 8 bit
  • Stop bit: 1 bit
  • Parity: Non
  • Flow control: Xon/Xoff

⑤ Press [TNC] again to enter Packet mode.

- "PACKET" also appears.

To select 9600 bps as the transfer rate from/to the target station, type HBAUD (or HB) 9600 and press [Enter] or [Return]. The default is 1200 bps.

- You must select the same transfer rate as the target station.

⑦ Type MYCALL (or MY) then your call sign (9 digits max.) and press [Enter] or [Return] to set your call sign on the TNC.

- You cannot use the default setting (NOCALL).

⑧ Tune to an appropriate frequency.

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

⑨ 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, "TNC_CON" 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.

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, he (or she) sends a notice to his (or her) node. Then this node passes the information to all its local stations besides another node. This transceiver can display received DX information and hold the latest information on up to 10 DX stations. Use this function to monitor the latest DX information in your local area. You cannot send DX information to a node, using the function.

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.

KENWOOD TH-D7A - Note: - 6

PROGRAMMING A GROUP CODE

Using a group code relieves you from receiving unwanted packets. The APRS on this transceiver supports the following three types of group codes.

All calls:

Program a 6-digit code that always starts with AP. You will receive all APRS packets which include AP in group codes. It does not matter whether or not the subsequent 4 digits match. The default on this transceiver is APK001; K001 stands for KENWOOD Ver.1.

Note: APRS packets, which are generated via various methods, include various codes instead of group codes. Using “All calls” allows you to receive packets which include the following codes.

GPSSYMQSTCQBEACON
ALLSKYWRNMAILIDSPCL

Special:

Enter "SPCL". You will receive only APRS packets that include SPCL as a group code. This code is generally programmed by all stations at a special event.

Alternate net:

Program any other code with a maximum of 6 digits. You will receive only APRS packets that include the exact same code. In order to reject other packets, this code should not include characters specified by the above two types.

Note: Menu 2-A allows you to enter up to 9 digits (not 6 digits) because of possible future enhancement of the group code system.

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.

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.

ParameterNumber of digipeatersDirection

22All
33All

11 2 (or more)^1 West
12 Many^2 North
13 Many^2 South
14 Many^2 East
15 Many^2 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.

SKY COMMAND II (TH-D7A ONLY)

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.

◆ 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.
