6 Power Lines

Minimum recommended distance for an outdoor
antenna from power lines is one and one-half times
the vertical height of the associated antenna support
structure. This distance allows adequate clearance
from the power lines if the support structure should
fail for any reason.

7 Ventilation

Locate the transceiver so as not to interfere with its
ventilation. Do not place books or other equipment
on the transceiver that may impede the free
movement of air. Allow a minimum of 4 inches
(10 cm) between the rear of the transceiver and the
wall or operating desk shelf.

8 W ater and Moisture

Do not use the transceiver near water or sources of
moisture. For example, avoid use near bathtubs,
sinks, swimming pools, and in damp basements and
attics.

9 Abnormal Odors

The presence of an unusual odor or smoke is often a
sign of trouble. Immediately turn the power OFF and
remove the power cable. Contact a dealer or the
nearest Service Center for advice.

10 Heat

Locate the transceiver away from heat sources such
as radiators, stoves, amplifiers or other devices that
produce substantial amounts of heat.

11 Cleaning

Do not use volatile solvents such as alcohol, paint
thinner, gasoline or benzene to clean the cabinet.
Use a clean cloth with warm water or a mild
detergent.

12 Periods of Inactivity

Disconnect the input power cable from the power
source when the transceiver is not used for long
periods of time.

13 Servicing

Remove the transceiver’s enclosure only to do
accessory installations described by this manual or

INSTALLATION

1

|nstall and connect an antenna system
{page 1}.

Install a ground system that satisfies DC
and RF grounding requirements {page 2}.

Install lightning protection to protect the
antenna system, your personal safety,
and your property {page 2}.

ANTENNA CONNECTION

The type of the antenna system, consisting of the
antenna, ground, and feed line, will greatly affect the
successful performance of the transceiver. Use a
properly adjusted 50 Ω antenna of good quality to let
your transceiver perform at its best. Use a good-quality
50 Ω coaxial cable and a first-quality connector for the
connection. Match the impedance of the coaxial cable
and antenna so that the SWR is 1.5:1 or less. All
connections must be clean and tight.

While the transceiver’s protection circuit will activate if
the SWR is greater than 2.5:1, do not rely on protection
to compensate for a poorly functioning antenna system.
High SWR will cause the transmit output to drop, and
may lead to radio frequency interference to consumer
products such as stereo receivers and televisions. You
may even interfere with your own transceiver. Reports
that your signal is garbled or distorted, especially at
peak modulation, may indicate that your antenna
system is not efficiently radiating the transceiver’s
power. If you feel a tingle from the transceiver’s cabinet
or the microphone’s metal fittings when you modulate,
you can be certain that, at the least, your coax
connector is loose at the rear of the radio and, at the
worst, your antenna system is not efficiently radiating
power.

Connect your antenna feed line to ANT 1. If you are
using two antennas, connect the second antenna to

ANT 2.

CAUTION:

◆

TRANSMITTING WITHOUT FIRST CONNECTING AN
ANTENNA OR OTHER MATCHED LOAD MAY DAMAGE THE
TRANSCEIVER. ALWAYS CONNECT THE ANTENNA TO THE
TRANSCEIVER BEFORE TRANSMITTING.

◆

USE A LIGHTNING ARRESTOR TO PREVENT FIRE,
ELECTRIC SHOCK, OR DAMAGE TO THE TRANSCEIVER.

Install and connect a DC power supply {page 2}.

Connect all accessories to the transceiver {pages 3, 60}.

GROUND CONNECTION

At the minimum, a good DC ground is required to
prevent such dangers as electric shock. For superior
communications results, a good RF ground is required,
against which the antenna system can operate. Both of
these conditions can be met by providing a good earth
ground for your station. Bury one or more ground rods,
or a large copper plate under the ground, and connect
this to the transceiver GND terminal. Use heavy gauge
wire or a copper strap, cut as short as possible, for this
connection. Just as for antenna work, all connections
must be clean and tight.

LIGHTNING PROTECTION

Consider carefully how to protect your equipment and
your home from lightning. Even in areas where
lightning storms are less common, there are usually a
limited number of storms each year. Take the time to
study the best way to protect your installation from the
effects of lightning by consulting reference material on
the subject.

The installation of a lightning arrestor is a start, but there
is more that you can do. For example, terminate your
antenna system transmission lines at an entry panel
that you install outside your home. Ground this entry
panel to a good outside ground, and then connect
appropriate feed lines between the entry panel and your
transceiver. When a lightning storm occurs, you can
ensure added protection by disconnecting the feed lines
from your transceiver.

CAUTION: DO NOT ATTEMPT TO USE A GAS PIPE (WHICH IS
CLEARLY DANGEROUS), AN ELECTRICAL CONDUIT (WHICH
HAS THE WHOLE HOUSE WIRING ATTACHED AND MAY ACT
LIKE AN ANTENNA), OR A PLASTIC WATER PIPE FOR A
GROUND.

DC POWER SUPPLY CONNECTION

In order to use this transceiver, you will need a separate

13.8 V DC power supply that must be purchased
separately . DO NOT directly connect the transceiver to
an AC outlet! Use the supplied DC power cable to
connect the transceiver to a regulated power supply. Do
not substitute a cable with smaller gauge wires. The
current capacity of your power supply must be 20.5 A
peak or more.

CAUTION:

◆

BEFORE CONNECTING THE DC POWER SUPPLY TO THE
TRANSCEIVER, BE SURE TO SWITCH THE TRANSCEIVER
AND THE DC POWER SUPPL Y OFF.

◆

DO NOT PLUG THE DC POWER SUPPLY INTO AN AC
OUTLET UNTIL YOU MAKE ALL CONNECTIONS.

First connect the DC power cable to the regulated DC
power supply and check that polarities are correct
(Red: positive, Black: negative). Then connect the
connectorized end of the DC power cable to the
DC 13.8 V power connector on the transceiver rear
panel. Press the DC power cable connector firmly into
the connector on the transceiver until the locking tab
clicks.

Ensure any external speaker used has an
impedance of 8 Ω. Use a 3.5 mm (1/8") diameter,
2-conductor (mono) plug. When an external speaker

is used, no sound is heard from the internal speaker.

WARNING! DO NOT CONNECT HEADPHONES TO THIS
JACK. THE HIGH AUDIO OUTPUT AT THIS JACK COULD
DAMAGE YOUR HEARING.

■ Keys and Keyboards for CW Operation

(PADDLE and KEY)

For CW operation using the internal electronic keyer,
connect a keyer paddle to the P ADDLE jack. For
CW operation without using the internal electronic
keyer, connect a straight key, semi-automatic key
(bug), electronic keyer, or the CW keyed output from
a Multimode Communications Processor (MCP) to
the KEY jack. The jacks mate with a 6.0 mm (1/4")
3-conductor plug and a 3.5 mm (1/8") 2-conductor
plug respectively . External electronic keyers or
MCPs must use positive keying to be compatible
with this transceiver. Use a shielded cable between
the key and the transceiver.

Note: Due to the full-featured functionality of the internal
electronic keyer, you may decide it’s unnecessary to connect
both a paddle and another type of key unless you specifically
want to use a keyboard for CW. It’s recommended that you
become familiar with the internal keyer by reading
“ELECTRONIC KEYER” {page 34} before making your decision.

ATT PRE-AMP

• After the “HELLO” message, the frequency and
other indicators appear.

To switch OFF the transceiver, press [POWER].

• After the transceiver has been switched ON, it can
then be switched OFF or ON by using only the
power switch on the DC power supply .

ADJUSTING VOLUME

RADIO FREQUENCY (RF) GAIN

Usually, set the RF control fully clockwise. If you are
having trouble hearing the desired signal due to
excessive atmospheric noise or interference from other
stations, it may help to reduce the RF gain.

To do this, take note of the peak S-meter reading of the
desired signal. Turn the RF control counterclockwise
until the S-meter reads the peak value that you noted.
Signals that are weaker than this level will be
attenuated. Reception of the station will be easier.

Depending on the type and gain of your antenna, and
the condition of the band, you may prefer leaving the RF
control turned counterclockwise by some amount
instead of turning it fully clockwise. When in FM mode,
always set the RF gain control fully clockwise.

In SSB mode, the transceiver automatically selects LSB
for frequencies lower than 9.5 MHz, and selects USB for

9.5 MHz or higher frequencies if the T uning control, the
MUL TI/CH control, or Mic [UP]/[DWN] is used to cross
the frequency of 9.5 MHz. This is also true if using the
front panel [UP] or [DOWN] button when the 1 MHz
Step mode is used.

ADJUSTING SQUELCH

The purpose of squelch is to silence audio output from
the speaker when no signal is present. When squelch
is set correctly , you will hear sound only while a station
is actually being received. The point at which ambient
noise on a frequency just disappears, called the squelch
threshold, depends on the frequency .

Turn the SQL control clockwise to just eliminate the
background noise when no signal is present. Many
operators prefer leaving the squelch control fully
counterclockwise unless operating full-carrier modes
such as FM or AM.

SELECTING A FREQUENCY

There are two simple methods to select a frequency .

A Manual Tuning

Turn the Tuning control or press Mic [UP]/[DWN] to
select the exact frequency .

WHAT IS A MENU?

Many functions on this transceiver are selected or
configured via a software-controlled Menu instead of
physical controls on the transceiver. Once familiar with
the Menu system, you will appreciate the versatility it
offers. No longer is the number and complexity of
features restricted by the physical controls and
switches on the front panel.

MENU A/ MENU B

The transceiver has two menus. These menus are
called Menu A and Menu B. The menus contain
identical functions; however, each menu can be
configured independently .

For example, you may enjoy two different kinds of
operating activities but you like to configure the
transceiver differently for each activity. Menu A could
be configured with one set of transmit signal
characteristics, DSP settings, programmable buttons,
frequency steps, etc. Menu B could be configured
completely differently. By switching from Menu A to
Menu B, you could instantly change Menu
configuration and button assignment to suit your
current operating style. Or, two operators may share a
single transceiver. By dedicating one Menu per
operator, each would always enjoy the best
configuration.

Note: The COM communication parameter setting in Menu No. 35
is shared by Menu A and Menu B.

MENU ACCESS

The following procedure explains how to check or
change any of the Menu items.

1 Press [MENU].

• “MENU” appears.

2 Press [A/B] to toggle Menu A or Menu B.

• “A” or “B” appears to show which Menu is

selected.

3 T urn the MULTI/CH control to select the desired

Menu No.

• Each time you change the Menu No. , you will

see a scrolling message that briefly describes the
current Menu No.

4 Press [UP], [DOWN], Mic [UP], or Mic [DWN] to

change the current selection for this Menu item.

SSB TRANSMISSION

SSB is now the most commonly-used mode on the HF
Amateur bands. Compared with other voice modes,
SSB requires a narrow bandwidth for communications.
SSB also allows long distance communication with
minimum transmit power. These reasons, combined
with the fact that modern Amateur transceivers deliver
reasonably good audio quality, make SSB the mode
that most prefer on HF.

Refer, if necessary, to “OPERATING BASICS”
beginning on page 13 for receiving details.

1 Select the operating frequency.
2 Press [LSB/USB] to select either upper or lower

sideband mode.

• “LSB” or “USB” appears to show which sideband
is selected.

6 BASIC COMMUNICATING

CW TRANSMISSION

CW operators know that this mode is a reliable method
of communicating under the worst conditions. Although
it’s true that newer digital modes rival CW as being
equally as useful in poor conditions, these modes do not
have the long history of service yet nor the simplicity
that CW can have.

This transceiver has a built-in electronic keyer that
supports a variety of functions. For details on using
these functions, refer to “ELECTRONIC KEYER”
{page 34}.

Refer, if necessary, to “OPERATING BASICS”
beginning on page 13 for receiving details.

1 Select the operating frequency.
2 Press [CW/FSK] to select CW mode.

• “CW” appears.

• To tune in another station so your transceiver is
precisely on their frequency , use Auto Zero-beat.
Refer to “AUTO ZERO-BEAT”.

• If you wish, you can press [REV] to switch
receive from the default upper sideband to the
lower sideband. “R” will appear.

3 Press [SEND].

• “RX” disappears and “TX” appears.

• No transmit carrier level adjustment is necessary.

• Refer to “CW BREAK-IN” {page 34} for
information on automatic TX/RX switching.

4 Begin sending.

• As you transmit, you should be hearing a
sidetone that lets you monitor your own sending.
Refer to “TX SIDETONE/ RX PITCH
FREQUENCY”.

5 Press [SEND] again to return to the receive mode.

• “TX” disappears and “RX” appears.

Note: Auto Zero-beating may fail if there are other interfering signals
on frequency.

Refer to “COMMUNICA TING AIDS” beginning on
page 29 for information about additional useful functions
for operating.

AUTO ZERO-BEAT

Use Auto Zero-beat before transmitting whenever you
need to tune in a CW station. Auto Zero-beat
automatically and exactly matches your transmit
frequency with the station that you are receiving.
Neglecting to do this will reduce your chances for being
heard by the other station.

1 Press [CW TUNE] to start Auto Zero-beat.

• “CW TUNE” appears.

• Your transmit frequency is automatically changed
so that the pitch of the received signal exactly
matches the TX sidetone/ RX pitch frequency
that you have set in your transceiver Menu
configuration. Refer to “TX SIDETONE/ RX
PITCH FREQUENCY” below for further
information on that frequency .

• When matching is completed, “CW TUNE”
disappears.

• If matching is unsuccessful, the previous
frequency is restored.

2 To interrupt Auto Zero-beat, press [CW TUNE] or

[CLR].

Note:

◆

If using RIT {page 30}, you may access Menu No. 48 and switch
the function ON. Auto Zero-beat then will match the RIT-offset
frequency with the station that you are receiving. When this
function is OFF, Auto Zero-beat changes the transmit frequency.

◆

You cannot start Auto Zero-beat if you have selected 1.0 kHz or

2.0 kHz for the DSP filter bandwidth.

◆

When using Auto Zero-beat, the matching error is within ±50 Hz
in most cases.

◆

Auto Zero-beat may fail if the keying speed of the target station is
too slow.

TX SIDETONE/ RX PITCH FREQUENCY

The transmit sidetone is the monitor tone you hear from
your transceiver as you send CW. It is necessary so
you can hear what you are transmitting. It is also useful
for checking that your key contacts are closing, the
keyer is functioning, or for sending practice without
putting a signal on the air.

Receive pitch refers to the frequency of the CW note
that you hear after tuning your receiver for maximum
receive signal strength.

On this transceiver, the frequency of the sidetone and
receive pitch are equal and selectable. Use Menu No.
20 to select the frequency that is most comfortable for
you.

To change the volume of the TX sidetone, use Menu
No. 21. The selections include OFF and 1 to 9. The
default is 4.

Note: The position of the AF control does not affect the volume of
the TX sidetone.

FM TRANSMISSION

FM operation on HF frequencies solves the problem of
how to have long distance voice communication with
the finest audio quality . When combined with the full­quieting aspect of FM signals that suppress background
noise on the frequency , FM can be the best method for
maintaining regular schedules with friends.

Refer, if necessary, to “OPERATING BASICS”
beginning on page 13 for receiving details.

1 Select the operating frequency.
2 Press [FM/AM] to select FM mode.

• “FM” appears.

• “RX” disappears and “TX” appears.

• Refer to “VOX” {page 31} for information on
automatic TX/RX switching.

4 Speak into the microphone in a normal tone and

level of voice.

• Speaking too close to the microphone, or too
loudly , may increase distortion and reduce
intelligibility .

• Microphone gain can be switched between low
and high for FM using Menu No. 17. Low is
usually appropriate; however, select high if
reports from other stations indicate that your
audio is weak. The MULTI/CH control has no
effect in FM mode.

TX DEVIATION SELECTION

Select wide band or narrow band TX deviation
depending on whether the other station is using wide
band or narrow band RX deviation. This selection is
crucial to avoid audio distortion or insufficient
intelligibility that the other station will encounter.

1 Press [FM/AM] to select FM mode.
2 Press [FILTER].

• The current filter selection appears.

AM TRANSMISSION

Each mode used on the HF Amateur bands has its own
advantages. Although long distance DX contacts may
be less common while using AM, the superior audio
quality characteristic of AM operation is one reason why
some prefer this mode.

When looking for others using AM, check the following
frequencies first:

• 3885, 7290, 14286, 21390, and 29000~29200 kHz
Refer, if necessary, to “OPERATING BASICS”

SPECIALIZED COMMUNICATING

SPLIT-FREQUENCY OPERA TION

Usually you can communicate with other stations using
the same frequency for receiving and transmitting. In
this case, you select only one frequency on either VFO
A or VFO B. However, there are cases where you must
select one frequency for receiving and another
frequency for transmitting. To do this requires two
VFOs. This is referred to as “split-frequency operation”.
One typical case that requires this type of operation is
described below.

When a rare or desirable DX station is heard, he or she
may immediately get many responses, all at the same
time. Often such a station is lost under the noise and
confusion of many calling stations. If you find that you
are suddenly being called as that rare or desirable
station, it is your responsibility to control the situation.
You may announce that you will be “listening up 5 (kHz,
from your present transmit frequency)”, or “listening
down between 5 and 10 (kHz)”.

1 Press [A/B] to select VFO A or VFO B.

•“tA” or “tB” appears to show which VFO is
selected.

2 Select the operating frequency.

• The frequency selected here will be used for
transmitting.

3 Press [A/B] to select the other VFO.
4 Select the operating frequency.

• The frequency selected on this VFO will be used
for receiving.

5 Press [SPLIT].

• “SPLIT” appears.

• Pressing [A/B] reverses the receive frequency
and the transmit frequency .

6 Press [SPLIT] to quit split-frequency operation.

• “SPLIT” disappears.

If you access Menu No. 07 and select ON, you can
recall a memory channel to use for either receiving or
transmitting. For more information, refer to “Memory­VFO Split Operation” {page 41} under “MEMORY
FEA TURES”.

Note: If you configure split frequencies using two different bands to
perform CW operation, select Semi Break-in.

TF-SET (TRANSMIT FREQUENCY SET)

TF-SET allows you to temporarily switch your transmit
frequency and receive frequency . Canceling this
function immediately restores the original transmit and
receive frequencies. By activating TF-SET, you can
listen on your transmit frequency , and change it while
listening. This allows you to check if the newly selected
transmit frequency is free of interference.

1 Activate split-frequency operation as explained in the

previous section.

2 Press and hold [TF-SET]. While holding down

[TF-SET], change the operating frequency by
turning the Tuning control or pressing Mic
[UP]/[DWN].

• The transceiver receives on the frequency that
you select, but the frequency shown on the sub­display stays unchanged.

3 Release [TF-SET].

• You are now receiving again on your original
receive frequency .

Successfully contacting a DX station in a pileup often
depends on making a well-timed call on a clear
frequency . The best way to know if your intended
transmit frequency is clear is to use TF-SET. Switch
your receive frequency and transmit frequency by using
TF-SET and listen. You soon will learn the rhythm of
the DX station and the pileup.

Use the information to select a relatively clear transmit
frequency and to transmit at the exact instant when the
DX station is listening but the majority of the group
aren’t transmitting. The more proficient you become at
using this function, the more DX you will contact.

Note:

◆

If you press [F.LOCK] before using TF-SET, pressing an
incorrect button by mistake will not change the original receive
frequency.

◆

TF-SET is disabled while transmitting.

◆

If you recalled a memory channel (excluding CH 90 to 99), you
must set Menu No. 08 to ON to use TF-SET to change the
frequency of the memory channel.

◆

An RIT frequency shift is not added; however, an XIT frequency
shift is added to the transmit frequency.

◆

TF-SET is also enabled while operating with the same TX/RX
frequency (non-split).

FM REPEATER OPERATION

Most Amateur radio voice repeaters use a separate
receive and transmit frequency. The transmit frequency
may be higher or lower than the receive frequency . In
addition, some repeaters may require the transceiver to
transmit a subtone before the repeater can be used.

Compared to simplex communication, you can usually
transmit over much greater distances by using a
repeater. Repeaters are typically located on a mountain
top or other elevated location. Often they operate at
higher ERP (Effective Radiated Power) than a typical
station. This combination of elevation and high ERP
allows communications over considerable distances.

HF repeaters operate only in the 29 MHz FM sub-band.
This special service combines the advantages of FM
operation, good fidelity with noise and interference
immunity , with the excitement of HF DX (long distance)
communications. Even on a quiet day , 10 meter FM
provides reliable around-town communications with the
potential for sudden DX from across the country or
around the world.

SELECTING SUBTONE FREQUENCY

Some 10-meter FM repeaters require the transceiver to
transmit a subtone, to prevent other repeaters on the
same frequency from locking each other up. The
required subtone frequency depends on the repeater
you are accessing. In Europe, a 1750 Hz tone is
generally used to access repeaters.

Select the subtone frequency you require via Menu
No. 18. The default is 88.5 Hz. The available choices
are shown in the table below.

FM CTCSS OPERATION

CTCSS is the abbreviation for Continuous Tone Coded
Squelch System. CTCSS uses subaudible tone
frequencies. While you are transmitting, a subtone that
you select is superimposed on your transmit signal.

Suppose that only stations “A”, “B”, and “C” are
programmed with the same subtone frequency. When
“A” calls, the squelch on only “B” and “C” opens. So
you can choose which stations will receive your
transmissions.

CONTINUOUS OR BURST SUBTONES?

In addition to selecting the frequency of the subtone,
you must choose the correct subtone duration. The
Continuous selection continuously sends the subtone
as long as the transceiver is transmitting. The Burst
selection sends a 500 ms subtone burst each time the
transceiver begins transmitting.

Select either Continuous or Burst via Menu No. 19. The
default is Continuous except on some European
versions.

• To quit CTCSS, press [AGC/TONE] again.

7 When you are called:

The squelch in your transceiver opens only when the
selected subtone is received.

When you make a call:

Press and hold Mic [PTT], or press [SEND].

• The selected subtone is superimposed on your
transmitted signal.

Note:

◆

When using split-frequency operation, select FM mode on both
VFOs to use CTCSS.

◆

While selecting 1750 Hz subtone, you cannot switch ON the
CTCSS.

DIGITAL OPERATION

Since Multimode Communications Processors (MCP)
have become popular, many Amateurs enjoy operating
using a number of digital modes. The power and
variety of Amateur radio increased greatly with the
development of MCP that can use your transceiver as
the communications link.

For example, it’s possible to take advantage of the
camaraderie found on RTTY, then move to Packet to
access an RBBS (Radio Bulletin Board System) to
download a recent shareware program you’ve heard
about, and then move again to AMT OR or PacTOR to
deposit mail in a regional mailbox for forwarding. After
that, you may switch to G-TORTM or Clover for a
lightning fast file transfer with a friend.

RTTY (FREQUENCY SHIFT KEYING)

Radioteletype operation uses frequency shift keying
(FSK) and the 5-bit Baudot code or the 7-bit ASCII code
to transmit information.

Consult “RTTY” {page 61} under “CONNECTING
PERIPHERAL EQUIPMENT” if you need installation
information.

1 Select the FSK shift via Menu No. 29.

• FSK shift is the difference in frequencies between
mark and space.

• The 170 Hz default is used on the Amateur
bands.

2 Access Menu No. 30, and select either “ON” (space)

or “OFF” (mark) to be transmitted when keying
down.

• The default is “OFF” (mark).

3 Access Menu No. 31, and select high tone (2125 Hz)

or low tone (1275 Hz) for mark.

• The high tone (default) is commonly used
nowadays.

4 Select the operating frequency.
5 Press [CW/FSK] to select FSK.

• “FSK” appears.

6 If necessary to be compatible with the station you

want to contact, press [REV] to reverse the
transceiver to the upper sideband.

• “R” appears beside “FSK”.

• Traditionally, the lower sideband is used for FSK
operation.

• Press [REV] again if you want to return to the
lower sideband.

7 Following the instructions provided with your MCP or

RTTY equipment, enter the key sequence at your
RTTY keyboard to select the transmit mode.

• “RX” disappears and “TX” appears.

• You may instead press [SEND] to manually
select the transmit mode.

8 Begin sending data from the keyboard.

• No transmit carrier or AF input level adjustment is
necessary .

• Use Menu No. 34 to select the appropriate AF
output level. The AF control cannot be used for
this adjustment.

9 When finished transmitting, enter the key sequence

from the keyboard to return to the receive mode.

• “TX” disappears and “RX” appears.

• If you pressed [SEND] in step 7, press [SEND]
again.

SLOW SCAN TV/ FACSIMILE

SSTV is now increasing in popularity as a result of the
capability of computers. Using this technique, you can
transmit and receive still monochrome or full-color
images. Instead of trying to describe your station, just
showing it is much faster. To do this, you require a scan
converter to translate your video images into audio
signals that can be fed into your transceiver. Or, to
begin more simply , you can use only your computer with
readily available software to perform this task. A TV set
and a video camera that you may already own will also
be useful tools.

The high resolution that is possible using facsimile (fax)
can allow you to exchange more detailed graphics than
SSTV allows. Due to the longer transmission times
required for fax, it’s best to use this mode when band
conditions are stable with strong signals.

Popular fax frequencies include the following:

• 7245, 14245, 21345 (Intern. Net), 28945 kHz
Operation on SSTV or fax mainly involves learning the

functionality of your computer application or accessory
hardware that supports these modes. Consult the
documentation that comes with your software or
accessory equipment.

Note: When operating either SSTV or fax, use a fast AGC setting
and switch OFF your Speech Processor for best results.

SATELLITE OPERATION

Though not as common as VHF/UHF satellite operation,
HF satellite operation is possible depending on which
satellites are currently in orbit around the Earth. When
HF propagation is poor, satellite operation can provide
an incentive to get back on the air. Since this
communications mode is so reliable, you may discover
you actually prefer satellite operation over the hunt-and­miss method of communicating via the ionosphere.

An example of a Mode K satellite that uses uplink and
downlink HF frequencies is the Radio Sputnik 12
(RS-12). Launched in the early 1990s, this satellite is in
a low Earth orbit and provides brief windows of
opportunity for use as it passes quickly over your
location. The satellite accepts SSB or CW signals on
the 15 meter band and outputs them on 10 meters.

This transceiver can also be used with Mode A
satellites, if you have an SSB/CW VHF transceiver.
Mode A satellites use a VHF uplink and an HF downlink.

If you’re interested in pursuing satellite operation,
contact AMSAT (Radio Amateur Satellite Corporation)
directly or via their internet Home page. This group of
satellite operators, located all over the world, support
the construction and operation of satellites. AMSAT can
provide you with the latest information regarding Mode
K and Mode A satellites that are currently in orbit.

RECEIVING

SELECTING YOUR FREQUENCY

In addition to turning the T uning control or pressing Mic
[UP]/[DWN], there are several other ways to select your

frequency . This section describes additional methods of
frequency selection that may save you effort and time.

■ Direct Frequency Entry

When the desired frequency is far removed from the
current frequency , directly entering a frequency from
the numeric keypad can be the fastest method.

1 Press [ENT].

• “- - . - - - . - -” appears.

2 Press numeric buttons [0] to [9] to enter the

frequency you desire.

• Pressing [ENT] fills the remaining un-entered
digits with 0 and completes entry .

• To select 1.85 MHz for example, press [0] for
the 10 MHz digit (first digit), because you can
also select 18.5 MHz on this transceiver.

• Pressing [CLR] cancels entry and restores
the previous frequency .

Note:

◆

Some digits cannot be entered for the 10 MHz digit (first
digit). Pressing one of those digits will cause that digit to be
entered in the 1 MHz position.

◆

When the 10 Hz digit (last digit) is entered, the digit 0 is
entered automatically for the 1 Hz digit, and frequency entry
is completed. The 1 Hz digit is not displayed.

◆

Attempting to enter a frequency that is outside the selectable
frequency range causes an alarm to be generated. The
entered frequency is rejected.

◆

When an entered frequency is accepted, RIT and XIT are
switched OFF, but the RIT or XIT frequency is not changed.

◆

After recalling memory channels 90 to 99 that have Start and
End frequencies stored, the receive frequency can be
changed by using Direct Frequency Entry within the
programmed range.

■ Using 1 MHz Steps

Pressing [UP]/[DOWN] on the front panel changes
Amateur bands. You can also use [UP]/[DOWN] to
change operating frequencies in steps of 1 MHz.

1 Press [1MHz].

2 Press [UP] or [DOWN].

• Holding down either button causes the
function to repeat.

3 To restore the original function, press [1MHz]

again.

• “1MHz” disappears.

If you prefer 100 kHz or 500 kHz steps instead of
1 MHz, use Menu No. 02. The default is 1 MHz.

■ Quick Changes

To move up or down in frequency quickly, use the
MUL TI/CH control. Turning this control changes the
operating frequency in 10 kHz steps.

• If you want to change the frequency step size,
use Menu Nos. 03 and 04. Select 1 kHz, 5 kHz,
10 kHz, 12.5 kHz, 20 kHz, or 25 kHz for FM, and
select 1 kHz, 5 kHz, or 10 kHz for the other
modes. The default for both Menu numbers is
10 kHz.

• When changing the operating frequency by using
the MUL TI/CH control, frequencies are rounded
such that new frequencies are multiples of the
frequency step size. To cancel this function,
access Menu No. 05 and select OFF.

• Within the AM broadcast band, the step size
automatically defaults to 9 kHz (U.S.A./Canada
versions: 10 kHz) for AM mode. This step size
can be switched between 9 kHz and 10 kHz via
Menu No. 06.

■ Fine Tuning

Usually, turning the Tuning control changes the
frequency in steps of 10 Hz for SSB, CW, and FSK
modes, and 100 Hz for FM and AM modes.
However, you can also change the step size to 1 Hz
for SSB, CW, and FSK modes, and to 10 Hz for FM
and AM modes.

1 Press [FINE].

• “FINE” appears.

2 Turn the T uning control to select the exact

frequency .

3 To cancel the function, press [FINE] again.

• “FINE” disappears.

■ Equalizing VFO Frequencies (A=B)

This function allows you to copy the frequency and
modulation mode of the active VFO to the inactive
VFO.

1 Select the frequency and mode on VFO A or

VFO B.

2 Press [A=B].

• The frequency and mode selected in step 1 are
copied to the inactive VFO.

3 Press [A/B] if you want to confirm that the

frequency was copied.

RIT (RECEIVE INCREMENTAL TUNING)

RIT provides the ability to change your receive frequency
by ±9.99 kHz in steps of 10 Hz without changing your
transmit frequency. If the Fine Tuning ([FINE]) function is
ON, the step size is 1 Hz. RIT works equally well with all
modulation modes and while using VFO mode or
Memory Recall mode.

1 Press [RIT].

• “RIT” and the RIT offset appear.

2 If required, press [CLEAR] to reset the RIT of fset to 0.
3 Turn the RIT/XIT control to change your receive

frequency .

4 To cancel RIT, press [RIT].

• The receive frequency is returned to the frequency
that was selected prior to step 1.

Note:

◆

When using Memory Recall, RIT only functions with a memory that
contains stored data.

◆

The frequency shift set by the RIT/XIT control is also used by the
XIT function. Therefore, changing or clearing the RIT offset also
affects the XIT offset.

The default time constant is slow for SSB, fast for CW,
fast for FSK, and slow for AM.

1 Assume that USB is currently selected.
2 Press [AGC/TONE].

Menu causes “ ” to appear beside the Menu No.

• High boost (Hb):
Emphasizes higher audio frequencies; effective for a

bassy voice.

• Formant pass (FP):
Improves clarity by suppressing audio frequencies

outside the normal voice frequency range.

• Bass boost (bb):
Emphasizes lower audio frequencies; effective for a

AGC (AUTOMATIC GAIN CONTROL)

When using modes other than FM, AGC selects the time
constant for the automatic gain control circuit.

Selecting a slow time constant will cause the receiver
gain and S-meter readings to react slowly to large input
changes. A fast time constant causes the receiver gain
and the S-meter to react quickly to changes in the input
signal. A fast AGC setting is particularly useful in the
following situations:

• Tuning rapidly

• Receiving weak signals

• Receiving high-speed CW

TRANSMITTING

VOX (VOICE-OPERATED TRANSMIT)

VOX eliminates the necessity of manually switching to
the transmit mode each time you want to transmit. The
transceiver automatically switches to transmit when the
VOX circuitry senses that you have begun speaking into
the microphone.

When using VOX, develop the habit of pausing between
thoughts to let the transceiver drop back to receive
briefly . You will then hear if anybody wants to interrupt,
plus you will have a short period to gather your thoughts
before speaking again. Your listener will appreciate
your consideration as well as respect your more
articulate conversation.

VOX can be switched ON and OFF independently for
CW and the other modes excluding FSK.

Press [VOX] to toggle VOX between ON and OFF.

• “VOX” appears when the function is ON.

■ Delay Time

If the transceiver immediately returns to receive too
quickly after you stop speaking, your final word may
not be transmitted. To avoid this, select the
appropriate delay time that allows all of your words
to be transmitted without an overly long delay after
you stop speaking.

1 Select SSB, FM, or AM mode.
2 Switch the VOX function ON.
3 Press [DELAY].

• The current setting appears. The default is 50.

4 While speaking into your microphone using your

normal level of voice, adjust the MUL TI/CH
control such that the transceiver switches to
receive a brief time after you stop talking.

• The selectable range is 5 to 100 (150 ms to
3000 ms) in steps of 5, and OFF.

5 Press [DELAY] again.

■ Microphone Input Level

To enjoy the VOX function, take time to set the gain
of the VOX circuit to the correct level. This level
controls the capability of the VOX circuit to detect the
presence or absence of your voice. When using CW
mode, this level cannot be adjusted.

1 Select SSB, FM, or AM mode.
2 Switch the VOX function ON.
3 Access Menu No. 16.
4 While speaking into your microphone using your

normal level of voice, select different settings
(default is 4) until the transceiver reliably switches
to transmit each time you speak.

• The selectable range is 0 to 9.

• The final selection should not allow
background noises near your operating
position to falsely switch the transceiver from
receive to transmit.

Note: Menu No. 16 is configurable even if VOX is OFF or while
you are transmitting.

The Speech Processor levels large fluctuations in your
voice while you speak. When using SSB, FM, or AM
mode, this leveling action effectively raises the average
transmit output power, resulting in a more
understandable signal. The amount of voice
compression is fully adjustable. You will notice that
using the Speech Processor makes it easier to be heard
by distant stations.

10 dB.

• Using higher compression will not improve your
signal clarity or apparent signal strength.
Excessively compressed signals are more
difficult to understand due to distortion and are
less pleasant to hear than signals with less
compression.

4 To switch the Speech Processor OFF, press [PROC]

again.

CUSTOMIZING TRANSMIT SIGNAL
CHARACTERISTICS

The quality of your transmitted signal is important
regardless of which on-the-air activity you pursue.
However, it’ s easy to be casual and overlook this fact
since you don’t listen to your own signal. The following
sub-sections provide information that will help you tailor
your transmitted signal.

■ Changing Transmit Bandwidth (SSB/AM)

Use Menu No. 13 to change the transmit bandwidth
between 2.4 kHz (normal) and 2.0 kHz (narrow).
The default is 2.4 kHz.

Bandwidth

2.4 kHz (Normal)

2.0 kHz (Narrow)

■ Equalizing Transmit Audio (SSB/FM/AM)

Use Menu No. 14 to change the transmit frequency
characteristics of your signal. You can select from
five different transmit profiles including the default flat
response . Selecting any of the following items from
the Menu causes “TX EQ.” to appear on the display .

• High boost (Hb):

Emphasizes higher audio frequencies; effective
for a bassy voice.

• Formant pass (FP):

Improves clarity by suppressing audio
frequencies outside the normal voice frequency
range.

• Bass boost (bb):

Emphasizes lower audio frequencies; effective
for a voice with more high frequency
components.

• Conventional (c):

Emphasizes by 3 dB frequencies at 600 Hz and
higher.

MONITORING TRANSMITTED SIGNALS

While operating in the SSB, FM, or AM mode,
monitoring your transmitted signals is a good method for
judging intelligibility by other stations. You may use this
function, for example, while selecting an optimum TX
equalizer profile.

Use Menu No. 47 to select 1 to 9. The larger the
number, the greater the monitor volume. The default is
OFF.

Note:

◆

When the monitor volume is high or the Speech Processor is ON,
speaker output audio may be picked up by your microphone,
resulting in a howling phenomenon. Use headphones if this
happens.

◆

Audio picked up before the modulation is output from the
speaker. So the quality of this audio slightly differs from the
quality of audio which other stations will hear.

◆

This function is not available in the CW or FSK mode.

◆

The position of the AF control does not affect the monitor volume.

TRANSMIT INHIBIT

Transmit Inhibit prevents the transceiver from being
placed in the transmit mode. No signals can be
transmitted if this function is ON.

• TX Inhibit OFF:Transmissions are possible.

• TX Inhibit ON: Transmissions are not possible.

Switch the function ON or OFF via Menu No. 38. The
default is OFF.

CHANGING FREQUENCY WHILE TRANSMITTING

Moving your frequency while transmitting is usually an
unwise practice due to the risk of interference to other
stations. However, if necessary, by using the Tuning
control you can change the operating frequency while
transmitting. You also can change the XIT offset
frequency in the transmit mode.

While transmitting, if you select a frequency outside the
transmit frequency range, the transceiver is
automatically forced to receive mode. If you selected
transmit mode by pressing [SEND], transmission will
not resume until you select a frequency inside the
transmit frequency range, and you press [SEND] again.

CW BREAK-IN

Break-in allows you to transmit CW without manually
switching between transmit and receive modes. T wo
types of Break-in are available, Semi Break-in and Full
Break-in.

Semi Break-in:

When the key contacts open, the transceiver
automatically waits for the passage of the time period
that you have selected. The transceiver then returns to
the receive mode.

Full Break-in:

As soon as the key contacts open, the transceiver
returns to the receive mode.

USING SEMI BREAK-IN OR FULL BREAK-IN

1 Press [CW/FSK] to select CW mode.

• “CW” appears.

2 Press [VOX].

• “VOX” appears.

3 Press [DELAY].

• The current setting (Full or delay time) appears.
The default is Full (“FBk”).

ELECTRONIC KEYER

This transceiver has a built-in electronic keyer that can
be used by connecting a keyer paddle to the
transceiver’s rear panel. Consult “Keys and Keyboards
for CW Operation” {page 3} for details regarding this
connection. This built-in keyer supports lambic
operation.

CHANGING KEYING SPEED

The keying speed of the electronic keyer is fully
adjustable. Selecting the appropriate speed is
important in order to send error-free CW that other
operators can copy solidly. Selecting a speed that is
beyond your keying ability will only result in mistakes. If
you select a speed that is close to the speed used by
the other station, you will obtain the best results.

1 Press [CW/FSK] to select CW mode.

• “CW” appears.

2 Press [KEY].

• The current keying speed appears. The default

• Available delay times are from 5 to 100 (50 ms to
1000 ms) in steps of 5.

5 Begin sending.

• The transceiver automatically switches to the

transmit mode.

• When Full is selected: The transceiver
immediately switches to the receive mode when
the key opens.

• When a delay time is selected: The transceiver
switches to the receive mode after the delay time
that you have selected has passed.

6 Press [DELAY] again.

Note: Full Break-in cannot be used with the TL-922/922A amplifier.

3 While keying the paddle and listening to the transmit

sidetone, turn the MUL TI/CH control to select the
appropriate speed.

• The selectable range is 0 to 100 in steps of 2.
The larger the number, the faster the speed.

4 Press [KEY] again to complete the setting.

Note: When using the semi-automatic “Bug” function, the selected

speed applies only to the rate that dots are sent.

AUTO WEIGHTING

The electronic keyer can automatically change the dot/
dash weighting. Weighting is the ratio of dash length to
dot length. The weighting changes with your keying
speed thus making your keying easier for other
operators to copy.

Use Menu No. 26 to switch Auto Weighting ON or OFF.
The default is ON. When Auto W eighting is OFF, the
weighting is locked at 3:1.

■ Reversible Auto Weighting

15
16

Auto Weighting increases the weighting as you
increase your keying speed. However, the electronic
keyer also can decrease the weighting as you
increase your keying speed.

To switch this function ON, access Menu No. 27, and
select ON. The default is OFF.

34

8 COMMUNICATING AIDS

CHANGING LOCKED-WEIGHT

Switching Auto W eighting OFF locks the dash/dot
weighting to 3:1. It is also possible to change this default
locked-weight. Use Menu No. 49 to select from
16 ratios, in the range from 2.5:1 to 4.0:1. “2.7”, visible
while making selections, for example, designates 2.7:1.

Note: When the Auto Weighting or Bug Key function is ON, the
selection made in Menu No. 49 is invalid.

BUG KEY FUNCTION

The built-in electronic keyer also can be used as a semi­automatic key . Semi-automatic keys are also known as
“Bugs”. When this function is ON, dots are generated in
the normal manner by the electronic keyer. Dashes,
however, are manually generated by the operator by
holding the keyer paddle closed for the appropriate
length of time for each dash.

To switch this function ON, access Menu No. 22, and
select ON. The default is OFF.

Note: When the Bug Key function is ON, CW Message Memory (see
below) cannot be used.

CW MESSAGE MEMORY

This transceiver has three memory channels for storing
CW messages. Each memory channel can store
approximately 50 characters. These memory channels
are ideal for storing contest exchanges that you want to
send repeatedly . Stored messages can be played back
to check message content or for transmitting.

The electronic keyer has a function that allows you to
interrupt playback and manually inject your own keying.
To switch this function ON, access Menu No. 28, and
select ON. The default is OFF.

The electronic keyer also can repeatedly play back the
message that you stored. To switch this function ON,
access Menu No. 23 and select ON. The default is OFF.

For repetitive message playback, you can change the
interval between each series of messages. Use Menu
No. 24, and select the time in the range of 0 to 60
seconds.

Note:

◆

This function cannot be used when the Bug Key function is ON.

◆

Operating the keyer paddle with Menu No. 28 OFF cancels
message playback. Even If message playback does not stop
because of your keying start timing, you can cancel playback by
pressing [CLR].

IF FILTER

The IF filters are designed for selecting the exact range
of intermediate frequencies that are sent to the next
stage in the receive circuit. Interference adjacent to the
desired signal can be reduced by selecting a narrow
bandwidth filter and/or shifting the center frequency of
the filter.

To more effectively remove interference, use the IF
filters with the DSP filters described on pages 37
and 38.

CHANGING IF FILTER BANDWIDTH

When adjacent frequency interference is present at both
sides of the desired signal, a narrow IF filter bandwidth
may be the best way to remove the interference.
Changing the filter bandwidth will not effect the current
receive frequency .

To use a narrow filter in SSB, CW, or FSK mode, install
the appropriate optional filter {page 58}, and select the
appropriate setting in Menu No. 46.

When in CW or FSK mode, the wide filter or the narrow
filter is automatically selected, depending on the
bandwidth of the DSP filter that you select. Refer to
“CHANGING RECEIVE BANDWIDTH” {page 37}. The
default in SSB or AM mode is wide bandwidth. In FM
mode, you cannot change the filter bandwidth.

Note: When you use Menu B, make sure to select the appropriate
filter bandwidth via Menu No. 46 in Menu B.

IF SHIFT

For SSB, CW, or FSK mode, shifting the center
frequency of the filter pass band is an additional method
of fighting adjacent frequency interference. Shifting this
center frequency does not change the current receive
frequency.

To remove interference that is higher in frequency than
the desired signal, turn the IF SHIFT control
counterclockwise. To remove interference that is lower
in frequency than the desired signal, turn the IF SHIFT
control clockwise.

NOISE BLANKER

Noise Blanker was designed to reduce pulse noise such
as that generated by automobile ignitions. Noise
Blanker does not function in FM mode.

DSP TOOLS

KENWOOD digital signal processing (DSP) technology
is used for the functions described in this section.

CHANGING RECEIVE BANDWIDTH

For improving the interference reduction capability, this
transceiver also provides audio frequency (AF) filters
designed using DSP technology. When in SSB, FM, or
AM mode, you can change the filter bandwidth by
altering its low cut-off frequency and/or high cut-off
frequency . For CW and FSK modes, you can change
the filter bandwidth by directly specifying a bandwidth.
Changing the filter bandwidth does not affect the current
receive frequency .

You can also monitor signals trimmed off by the above
DSP filters. Consult “PROGRAM FUNCTION
BUTTON” {page 49} and assign the DSP Filter Monitor
function (No. 53) to any [PF] button. Press and hold the
[PF] button to monitor the trimmed signals; the DSP
filters will restore the default bandwidths. Release the
button to quit the function. You may use this function to
check how adjacent frequencies are in use.

Press [B.C.] to toggle Beat Cancel ON or OFF.

• “BEA T CANCEL” appears when the function is ON.

Note: While receiving intermittent CW signals, the transceiver

sounds clicks. This does not indicate a malfunction.

If attenuation is not satisfactory , press [B.C.] for
1 second or longer to enhance the attenuation effect; a
beep sounds, but no change occurs on the display.
Pressing [B.C.] for 1 second or longer again restores
the original attenuation level.

Note:

◆

The Enhanced Beat Cancel setting is cleared when the power to
the transceiver is turned OFF .

◆

Enhanced Beat Cancel may adversely affect desired signals
slightly because of its stronger effect.

NOISE REDUCTION

This transceiver provides two types of Noise Reduction
functions, 1 and 2, for reducing random noise which
interferes with the desired signal. Just trying them both
is the easiest way to judge which function works more
effectively under the current condition. Normally select
Noise Reduction 1 in SSB mode and select Noise
Reduction 2 in CW mode.

Note: Using Noise Reduction 2 in SSB mode may lower the clarity
of signals or induce pulse noise depending on conditions.

Press [N.R.] to toggle between Noise Reduction 1,
Noise Reduction 2, and OFF.

• “N. R. 1” or “N.R. 2” appears depending on which
function is selected.

Note: A different selection can be made between two groups of
modes; one group includes SSB, FM, and AM, and the other group
includes CW and FSK. So you need not change the selection each
time you switch modes between the two groups.

■ Changing NR1 Performance

Use Menu No. 51 to change the effect of Noise
Reduction 1. Switch Noise Reduction 1 ON, then
select level 1 to 9 in this menu while receiving
signals. The default is “Auto”; this selection provides
an optimum effect according to the strength of the
received signal.

Note:

◆

Using a high NR1 level and Beat Cancel simultaneously may
cause noise to stand out; this does not indicate a malfunction.

◆

When changing the NR1 level in the menu, you will hear
sound momentarily caused by an internal operation change;
this does not indicate a malfunction.

■ Setting NR2 Time Constant

You can change the correlation time for Noise
Reduction 2. When in SSB, select the correlation
time that allows you to hear signals with more clarity.
When receiving CW, it is best to select the longest
correlation time that allows reliable reception. The
longer the correlation time, the better S/N.

The default is 20 ms.

MEMORY FEATURES

MICROPROCESSOR MEMORY BACKUP

This transceiver uses a lithium battery to retain the user­specified memory items. Switching OFF the power will
not erase the Menu setups or memory channels. The
lithium battery life is approximately 5 years.

If you find the transceiver powers-up with default
settings, and VFO and memory channel data is lost,
have the lithium battery replaced. Contact an authorized
KENWOOD service facility or dealer.

CONVENTIONAL MEMORY

Conventional memory is used for storing data that you
want to recall many times in the future. For example,
you may store the frequency where you regularly meet
your club members.

This transceiver provides 100 Conventional memory
channels, in total, numbered 00 to 99. Channels 90 to
99 are designed for programming VFO tuning ranges
and scan ranges. The data that you can store is listed
below:

STORING DATA IN MEMORY

There are 2 methods for storing transmit/receive
frequencies and associated data in memory channels
00 to 89. Use either method depending on the
relationship of the receive and transmit frequencies that
you store:

• Simplex channels:
RX frequency = TX frequency

• Split-frequency channels:
RX frequency ≠ TX frequency

Memory channels 90 to 99 can also be used as simplex
channels.

Note: When RIT or XIT is ON, the frequency that includes the RIT
or XIT offset will be stored.

QUICK MEMORY

Quick memory is designed for quickly and temporarily
saving data without specifying a particular memory
channel. Use Quick memory to store data that you will
not need during future operating sessions. For
example, as you tune across the band looking for DX, it
is convenient to store stations that you want to contact.
You can quickly jump between several different
memory channels as you monitor them.

This transceiver provides five Quick memory channels
that can store the following data:

current speed (P1: maximum, P9: minimum).

• When in FM mode, Scan automatically stops on
a channel in which a signal is present. The
transceiver remains on the same channel for
either a short time (Time-operated mode) or until
the signal drops (Carrier-operated mode),
depending on which one you select via Menu
No. 10. Refer to “MEMORY SCAN” for further
information.

4 To stop Scan, press [SCAN] or [CLR].

Note:

◆

If you have turned the SQL control clockwise far beyond the
squelch threshold when in FM mode, Scan may fail to stop at a
channel in which a signal is present. If this happens, turn the
SQL control slightly counterclockwise.

◆

If you press [SCAN] before storing any frequency range, then the
lower and upper frequency limits of the transceiver are stored in
memory channel 90, and Program Scan is activated using this
channel.

◆

When the current receive frequency is within one of the ranges
that you select by channel numbers, Scan starts with the current
frequency. The operating mode stored in the channel with that
range is used.

◆

When the current receive frequency is outside all the ranges that
you select by channel numbers, Scan starts with the start
frequency stored in the smallest channel number.

◆

Operating mode can be changed during scanning, but the
memory channel is overwritten with the changed mode.

◆

When the current Scan range is smaller than a single step of the
MULTI/CH control, turning this control clockwise causes Scan to
jump to the start frequency, and counterclockwise to the end
frequency.

◆

Starting Program Scan switches OFF the RIT and XIT functions.

MEMORY SCAN

Memory Scan monitors all memory channels in which
you stored frequencies (All-channel Scan) or only a
desired group of memory channels (Group Scan).

Scan automatically stops at a channel in which a signal
is present. The transceiver remains on the same
channel for either a short time (Time-operated mode) or
until the signal drops (Carrier-operated mode). Use
Menu No. 10 to select either mode. The default is
Time-operated.

Time-operated mode:

After stopping on a busy channel and waiting
approximately three seconds, Scan checks the channel
again. If the channel is still busy, Scan waits another
three seconds then restarts. If the channel is not busy
three seconds after stopping, Scan restarts immediately .

Carrier-operated mode:

Scan restarts approximately two seconds after the
signal drops.

You can lock out the memory channels that you prefer
not to monitor while scanning. To do this refer to
“Memory Channel Lockout” {page 44}.

ALL-CHANNEL SCAN

Use the following procedure to monitor all memory
channels that contain frequency data.

QUICK DATA TRANSFER

This transceiver has the capability to quickly and
conveniently transfer the receive frequency and mode to
another compatible transceiver. Compatible
transceivers include:

• TS-570S/570D • TS-850S

• TS-870S • TS-690S

• TS-950SDX • TS-450S
Data Transfer could be useful while contesting. A

spotting station that is searching for new contest
multipliers can quickly transfer a frequency over to the
running (main) station.

SETTING UP

■ Equipment Needed

In addition to a compatible transceiver, the following
equipment is required:

Transfer to TS-570 or TS-870S:

• One cross-wired cable
This cable must have a 9-pin RS-232C female

connector at both ends.

Transfer to a transceiver other than TS-570 and
TS-870S:

• KENWOOD IF-232C interface unit

• One cross-wired cable
This cable must have a 9-pin RS-232C female

connector at one end and a 25-pin RS-232C
female connector at the other end.

• One straight cable
This cable must have a 6-pin DIN male connector

at both ends.

■ Connections

For diagrams on how to connect the two
transceivers, see “CONNECTING PERIPHERAL
EQUIPMENT ” {page 60}.

USING QUICK TRANSFER

When connecting with another TS-570 or the TS-870S,
use the same COM connector baud rate on each
transceiver. If transferring to or from other KENWOOD
transceivers, select 4800 bps and 2 stop bits on the
TS-570. Use Menu No. 35 to select these parameters.

Note: While transferring data, other functions may work slowly.

■ Transferring Data

The TS-570 transceiver works as the Master
sending data to the Slave transceiver.

1 Switch ON the Transfer function on each

transceiver.

• On the TS-570, access Menu No. 36 and
select ON. For the compatible transceiver,
check the instruction manual that came with
the transceiver.

2 On the Master, while in VFO mode, select an

operating frequency and mode.

3 On the Master, press QUICK MEMO [M.IN].

• When using another TS-570 as the Slave,
“CTRL” appears on the Slave.

• The displayed data is stored in Quick memory
channel 1 on the Master and transferred to
the Slave.

Note: If the Master has RIT switched ON, the offset frequency
is added to the receive frequency to be transferred.

■ Receiving Data

The TS-570 transceiver works as the Slave,
receiving data from the Master transceiver. The
Slave can receive data using either Quick memory
channel 1 or the VFO.

1 Switch ON the Transfer function on each

transceiver.

• On the TS-570, access Menu No. 36 and
select ON. For the compatible transceiver,
check the instruction manual that came with
the transceiver.

2 On the Slave, access Menu No. 37 and select

either OFF (Quick memory channel 1) or ON
(the VFO).

• The default is Quick memory.

3 On the Master, perform the appropriate operation

to send data.

• For the correct method, check the instruction
manual that came with the transceiver.

Note:

◆

If you always use the TS-570 just to receive, activate TX
Inhibit via Menu No. 38 to avoid unintentional transmission.

◆

When the Slave receives data using the VFO programmed
with a simplex frequency, the received data replaces the data
on both VFOs. On the Slave, both RIT and XIT are set to
OFF.

◆

When the Slave receives data using the VFOs programmed
with split frequencies, the received data replaces the data
only on the TX side of the VFO. On the Slave, XIT is set to
OFF but RIT is not changed.

As explained in “ANTENNA CONNECTION” {page 1},
matching the impedance of the coaxial cable and
antenna is very important. To do this, you have the
choice of using the internal or an external tuner. This
section describes how to use the internal tuner. For the
external tuner, consult the instruction manual that comes
with the tuner.

• With an external tuner connected to the ANT 1
connector, you cannot select ANT 1 here.
Selecting ANT 1 in this situation always causes
the internal tuner to be bypassed.

• “AT” appears to show that the internal tuner is in­line (not bypassed).

• CW mode is automatically selected and tuning
starts.

• “AT” blinks, and “TX” and “CW” appear.

• To cancel tuning for any reason, press
[A T TUNE] again.

• If the SWR of the antenna system is extremely
high, an alarm, Morse code “SWR”, is output and
the internal tuner is bypassed. Before retrying
tuning, adjust the antenna system to lower the
SWR.

• After successful tuning, “AT” stops blinking, and
“TX” and “CW” disappear.

• If tuning does not finish within about 20 seconds,
an alarm sounds. Press [A T TUNE] to stop the
alarm and tuning.

Note:

◆

The internal tuner will not tune outside the authorized transmit
limits of Amateur bands.

◆

Pressing [AT TUNE] for more than one second while transmitting
interrupts transmitting and starts tuning.

◆

While using a different antenna tuner band for transmitting and
receiving with Menu No. 11 ON, received signals bypass the
internal tuner.

◆

While using CW Full Break-in, the internal tuner will be in-line for
both transmitting and receiving.

◆

Tuning will automatically turn off after approximately 60 seconds.
In addition, “AT” will disappear and the error beeps will stop.

◆

Tuning still may continue when the SWR meter indicates 1:1.
This happens because of the tuning algorithm, and does not
indicate a malfunction.

◆

Even though the SWR meter shows more than one segment, the
internal tuner may not function for retuning. This does not
indicate a malfunction. It happens because of an unavoidable
SWR calculation algorithm error between 10 W (approx.) transmit
power for tuning and 100 W transmit power.

◆

If tuning does not finish although the SWR meter indicates
smaller than 3:1, adjust the antenna system to lower the SWR,
then retry tuning.

◆

Tuning may not lower the SWR to 1:1 depending on conditions.

PRESETTING

After each successful tuning session, the Preset
function stores the position of the tuning capacitor in
memory . The position of the capacitor is stored for each
of the antenna tuner bands (see table below) and for
each antenna connector (ANT 1 and ANT 2).

Press [A T TUNE] and release it immediately.

• “AT” will appear to show that the internal tuner is in­line (not bypassed).

• Each time you go across the antenna tuner band,
the Preset function automatically positions the tuning
capacitor without need for retuning. If no Preset
data exists for a particular band/antenna
combination, then the default data for 50 Ω is used.

Note: Tuning may restart to obtain the optimum matching condition
although the current antenna tuner band has the preset data. This
does not indicate a malfunction.

APPENDIX: COM CONNECTOR PROTOCOL

HARDWARE DESCRIPTION

This transceiver uses a full-duplex, asynchronous, serial
interface for communicating through the male 9-PIN
RS-232C COM connector. Bytes are constructed with 1
start bit, 8 data bits, and 1 stop bit (4800 bps can be
configured for 1 or 2 stop bits). No parity is used. The
pinout and the pin functions of the COM connector are
as shown below:

CONTROL OPERATION

Most computers handle data in the form of “bits” and
“bytes”. A bit is the smallest piece of information that
the computer can handle. A byte is composed of eight
bits. This is the most convenient form for most
computer data. This data may be sent in the form of
either serial or parallel data strings. The parallel method
is faster but more complicated, while the serial method
is slower and requires less complicated equipment. The
serial form is, therefore, a less expensive alternative.

Serial data transmission uses time-division methods
over a single line. Using a single line also offers the
advantage of reducing the number of errors due to line
noise.

Only 3 lines are required theoretically for control of the
transceiver via the computer:

• Transmit data

• Receive data

• Ground
From a practical standpoint, it is also necessary to

incorporate some means of controlling when this data
transfer will occur. The computer and transceiver
cannot be allowed to send data at the same time! The
required control is achieved by using the RTS and CTS
lines.

For example, the transceiver is placed into the transmit
mode whenever the character string “TX;” is sent from
the computer. The character string “TX;” is called a
computer control command. It tells the transceiver what
to do. There are numerous commands available for
control of the transceiver. These commands may be
incorporated into a computer program written in any
high level language. Programming methods vary from
computer to computer; therefore, refer to the instruction
manuals provided with the terminal program and
computer.

RXD: Transmit data is serial data transferred from the
transceiver to the computer.

TXD: Receive data is serial data transferred from the
computer to the transceiver.

GND: Signal ground pin

RTS: This signal is applied to the transceiver. It is used

to inhibit transmit data from the transceiver when the
computer is not ready to receive the data. Transmit
data is inhibited when the level is low.

CTS: This signal is applied from the transceiver. It is
used to inhibit transmit data from the computer when
the transceiver is not ready to receive the data.
Transmit data is stopped when the level is low.

APPENDIX ●

COMPUTER CONTROL COMMANDS

A computer control command is composed of an
alphabetical command, various parameters, and the
terminator that signals the end of the control command.

EXAMPLE: Command to set VFO A to 7 MHz

FA 00007000000 ;

Terminator

Parameters

Alphabetical command

Commands can be classified as shown below:

Input
command
(Input to the

transceiver)
Computer
control
commands

Output
command
(From the
transceiver)

For example, note the following in the case of the FA
command (Frequency of VFO A):

• To set the frequency to 7 MHz, the following
command is sent from the computer to the
transceiver:

“FA00007000000;” (Set command)

• To read the frequency of VFO A, the following
command is sent from the computer to the
transceiver:

“FA;” (Read command)

• When the Read command above has been sent, the
following command is returned to the computer:

“FA00007000000;” (Answer command)

Note:

◆

Do not use the control characters 00 to 1Fh since they are either
ignored or cause a “?” answer.

◆

Program execution may be delayed while turning the Tuning
control rapidly.

◆

Receive data is not processed if the frequency is entered from
the keypad.

■ Alphabetical Commands

Set command
(Sets a
particular condition)

Read command
(Reads an answer)

Answer command
(Transmits a condition)

■ Parameters

Parameters are used to specify information
necessary to implement the desired command. The
parameters to be used for each command are
predetermined. The number of digits assigned to
each parameter is also predetermined. Refer to the
Parameter Table {page 73} and the Computer
Control Command Tables {page 75} to configure the
appropriate parameters.

When configuring parameters, be careful not to
make the following mistakes.

(correct parameter: “IS+1000”)
IS1000; Not enough parameters specified

(No direction given for the IF shift)

IS+100; Not enough digits

(Only three frequency digits given)

IS + 1000; Unnecessary characters between

parameters

IS+10000; Too many digits

(Five frequency digits given)

Note: If a particular parameter is not applicable to this
transceiver, the parameter digits should be filled using any
character except the ASCII control codes (00 to 1Fh) and the
terminator (;).

■ Terminator

To signal the end of a command, it is necessary to
use a semicolon (;). The digit where this special
character must appear differs depending on the
command used.

■ Error Messages

In addition to the Answer command, the transceiver
can send the following error messages.

Error

Message

?;

• Command syntax was incorrect.

Reason for Error

• Command was not executed due to
the current status of the transceiver
(even though the command syntax
was correct).

Note: Occasionally this message may not
appear due to microprocessor transients in the
transceiver.

E;

A communication error occurred such
as an overrun or framing error during a
serial data transmission.

O;

Receive data was sent but processing
was not completed.

A command consists of 2 alphabetical characters.
You may use either lower or upper case characters.
The commands available for this transceiver are
listed in the Alphabetical Command Table {page 72}.
