PRECAUTIONS

Please read all safety and operating instructions before

using this transceiver. For best results, be aware of all

warnings on the transceiver and follow these operating

instructions. Retain these safety and operating

instructions for future reference.

1 Power Source

Connect this transceiver only to the power source

described in the operating instructions or as marked

on the transceiver itself.

2 Power Cable Protection

Route all power cables safely. Ensure the power

cables can neither be walked upon nor pinched by

items placed near or against the cables. Pay

particular attention to locations near AC receptacles,

AC outlet strips and points of entry to the transceiver.

3 Electrical Shocks

Take care not to drop objects or spill liquids into the

transceiver through enclosure openings. Metal

objects, such as hairpins or needles, inserted into

the transceiver may contact voltages resulting in

serious electrical shocks. Never permit children to

insert any objects into this transceiver.

4 Grounding and Polarization

Do not attempt to defeat methods used for

grounding and electrical polarization in the

transceiver, particularly involving the input power

cable.

5 Outdoor Antenna Grounding

Adequately ground all outdoor antennas used with

this transceiver using approved methods.

Grounding helps protect against voltage surges

caused by lightning. It also reduces the chance of a

build-up of static charges.

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.

7Ventilation

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.

8Water 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

accessory manuals. Follow provided instructions

carefully to avoid electrical shocks. If unfamiliar with

this type of work, seek assistance from an

experienced individual, or have a professional

technician do the task.

14 Damage Requiring Service

Enlist the services of qualified personnel in the

following cases:

a) The power supply or plug is damaged.

b) Objects have fallen or liquid has spilled into the

transceiver.

c) The transceiver has been exposed to rain.

d) The transceiver is operating abnormally or

performance has degraded seriously.

e) The transceiver has been dropped or the

enclosure damaged.

INSTALLATION

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.

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.

REPLACING FUSES

If the fuse blows, determine the cause then correct the

problem. After the problem is resolved, only then

replace the fuse. If newly installed fuses continue to

blow, disconnect the power plug and contact your

dealer or nearest Service Center for assistance.

CAUTION:

REPLACE BLOWN FUSES ONLY AFTER

INVESTIGATING AND CORRECTING THE CAUSE OF THE

FAILED FUSE. ALWAYS REPLACE A BLOWN FUSE BY A NEW

FUSE WITH THE SPECIFIED RATINGS.

1 INSTALLATION

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 SUPPLY OFF.

◆

DO NOT PLUG THE DC POWER SUPPLY INTO AN AC

OUTLET UNTIL YOU MAKE ALL CONNECTIONS.

■ Microphone (MIC)

To communicate in the voice modes, connect to the

MIC connector a microphone having an impedance

between 250 Ω and 600 Ω. Insert the connector

from your microphone fully, then screw the retaining

ring clockwise until snug. Compatible microphones

include the MC-43S, MC-47, MC-60A, MC-80,

MC-85, and MC-90. Do not use the MC-44,

MC-44DM, MC-45, MC-45E, MC-45DM,

MC-45DME, MC-52DM, or MC-53DM microphone.

REAR PANEL

■ External Speaker (EXT SP)

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 PADDLE 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.

e Press and hold the [AT TUNE] button to allow the

built-in antenna tuner to function.

•“AT” blinks and “TX” appears.

•Tuning should be completed in less than

approximately 20 seconds. “AT” stops blinking

and “TX” disappears.

• If tuning is not completed in approximately 20

seconds, error beeps sound. Press

[ATTUNE] to stop the error beeps and to quit

tuning. Check your antenna system before

continuing.

Note:

Tuning will automatically turn off after approximately

60 seconds. In addition, “AT” will disappear and the error beeps

will stop.

r SSB: Press the [MIC] button to activate the

Microphone Gain Setting function.

• “MIC-50” appears.

CW: Skip this step.

t Press the [SEND] button.

OPERATING BASICS

SWITCHING POWER ON/OFF

Switch ON the DC power supply, then press and hold

down [

] (POWER) until “HELLO” appears on the

display. Release [ ] (POWER) when you see “HELLO”.

• 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

AUDIO FREQUENCY (AF) GAIN

Turn the AF control clockwise to increase the audio

level and counterclockwise to decrease the level.

Note:

The position of the

control does not affect the volume of

“beeps” caused by pressing buttons nor the CW transmit sidetone.

Also, the audio level for Packet operation is independent of the

control setting.

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.

SELECTING VFO A OR VFO B

VFO A and VFO B are modes that allow any desired

frequency to be selected within the frequency range of

the transceiver. VFO A and VFO B function

independently so that different or the same frequencies

can be selected for each VFO.

Press [A/B] to toggle between VFO A and VFO B.

•“tA” or “tB” appears and shows which VFO is

selected.

SELECTING A BAND

1 If “1MHz” is visible on the display, first press [1MHz]

to exit from the 1MHz Step mode.

• “1MHz” should disappear.

2 Press [UP] or [DOWN].

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.

B Direct Frequency Entry (Keypad)

Press [ENT], then directly enter the desired

frequency using the numeric keypad. For details,

refer to “Direct Frequency Entry” {page 29}.

FRONT PANEL METER

The multifunction meter measures the parameters in the

table below. The appropriate meters automatically

become functional according to which state the

transceiver is in. Peak readings for the S-meter, ALC,

SWR, COMP, and PWR functions are held for a brief

moment.

Note:

◆

The COMP meter functions only when the Speech Processor is

ON while using SSB, FM, or AM mode. When the COMP meter

appears, the SWR meter disappears.

◆

Peak Hold readings cannot be deactivated on this transceiver.

SELECTING A MODE

Depending on which operating mode you want to select,

press the [LSB/USB], [CW/FSK], or [FM/AM] button.

The second function on each button is accessed by

again pressing the same button. For example,

repeatedly pressing [LSB/USB] toggles between LSB

and USB modes.

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 Tuning control, the

MULTI/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.

sections in “BASIC COMMUNICATING” beginning on

page 20.

Note:

When CW, FSK, or AM is selected, the transmit carrier level is

automatically adjusted according to the selected mode.

SELECTING TRANSMIT POWER

It’s wise, and required by law, to select the lowest

transmit power that allows reliable communication.

Reducing power lowers the risk of interfering with others

on the band. On this transceiver, it is possible to

change output power while transmitting.

1 Press [PWR].

• The current transmit power appears.

2 Turn the MULTI/CH control counterclockwise to

reduce power and clockwise to increase power.

• The displayed transmit power changes.

• SSB/CW/FSK/FM: Transmit power can be

changed from 5 W to 100 W in steps of 5 W.

• AM: Transmit power can be changed from 5 W to

25 W in steps of 5 W.

3 Press [PWR] again to complete the setting.

Note:

The transmit power can be separately selected for the AM

mode independent of the other modes.

MICROPHONE GAIN

The microphone gain is finely adjustable in the SSB or

AM mode. A different level can be selected between

when the Speech Processor {page 32} is ON and when

the Speech Processor is OFF.

1 Press [MIC].

• The current microphone gain level appears. The

default is 50.

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

• “TX” appears.

3 SSB: While speaking into the microphone, adjust

the MULTI/CH control so that the ALC meter reflects

according to your voice level.

AM: While speaking into the microphone, adjust the

MULTI/CH control so that the calibrated power meter

slightly reflects according to your voice level.

4 Press [SEND] again or release Mic [PTT].

• “TX” disappears.

5 Press [MIC] again.

For the FM mode, set the microphone gain by

accessing Menu No. 17 {page 17} and selecting either

“L” (low) or “H” (high).

Note:

◆

When using the optional MC-90 microphone in FM mode, select

high microphone gain. The microphone sensitivity is low in FM

mode and this may cause insufficient modulation.

◆

When using a microphone that has an amplifier, be careful that

the output of the amplifier is not too large.

MENU SETUP

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 Turn 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.

5 Press [MENU] or [CLR] to exit Menu mode.

BASIC COMMUNICATING

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.

3 Press [MIC] to activate the Microphone Gain Setting

function.

• The current gain level appears

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

• “RX” disappears and “TX” appears.

• Refer to “VOX” {page 31} for information on

automatic TX/RX switching.

5 Speak into the microphone and adjust the

MULTI/CH control so that the ALC meter reflects

according to your voice level.

• Speak in a normal tone and level of voice.

Speaking too close to the microphone, or too

loudly, may increase distortion and reduce

intelligibility.

•You may want to use the Speech Processor.

Refer to “SPEECH PROCESSOR” {page 32} for

details.

6 Release Mic [PTT], or press [SEND] again, to return

to the receive mode.

• “TX” disappears and “RX” appears.

7 Press [MIC] again to quit the Microphone Gain

Setting function.

Refer to “COMMUNICATING AIDS” beginning on

page29 for information about additional useful functions

for operating.

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 “COMMUNICATING 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

control does not affect the volume of

the TX sidetone.

6 BASIC COMMUNICATING

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 full-

quieting 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.

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

• “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.

3 Turn the MULTI/CH control to select Wide

(“FM-WID”) or Narrow (“FM-NAR”).

4 Press [FILTER] to complete the setting.

Refer to “COMMUNICATING AIDS” beginning on

page29 for additional information about useful functions

for operating.

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”

beginning on page 13 for receiving details.

1 Select the operating frequency.

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

• “AM” appears.

3 Press [MIC] to activate the Microphone Gain Setting

function.

• The current gain level appears.

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

• “RX” disappears and “TX” appears.

• No transmit carrier level adjustment is necessary.

• Refer to “VOX” {page 31} for information on

automatic TX/RX switching.

5 Speak into the microphone and adjust the

MULTI/CH control so that the calibrated power meter

slightly reflects according to your voice level.

• Speak in a normal tone and level of voice.

Speaking too close to the microphone, or too

loudly, may increase distortion and reduce

intelligibility.

•You may want to use the Speech Processor.

Refer to “SPEECH PROCESSOR” {page 32} for

details.

6 Release Mic [PTT], or press [SEND] again, to return

to the receive mode.

• “TX” disappears and “RX” appears.

7 Press [MIC] to quit the Microphone Gain Setting

function.

Refer to “COMMUNICATING AIDS” beginning on

page29 for information about additional useful functions

for operating.

SPECIALIZED COMMUNICATING

SPLIT-FREQUENCY OPERATION

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 “Memory-

VFO Split Operation” {page 41} under “MEMORY

FEATURES”.

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 sub-

display 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).

7 SPECIALIZED COMMUNICATING

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.

VFO Split Operation” {page 41} under “MEMORY

FEATURES”.

The data that you select in steps 1 to 9 except for

subtone duration can be stored in memory. Refer to

“Split-Frequency Channels” {page 40}.

Note:

◆

When operating through a repeater, over deviation caused by

speaking too loudly into the microphone can cause your signal to

“talk-off” (break up) through the repeater.

◆

7 SPECIALIZED COMMUNICATING

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.

Note:

Use Nos. 01 to 39 shown in the table above when selecting

subtone frequencies via Computer Control {page 51}.

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.

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.

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

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

selected.

2 Select the desired subtone frequency via Menu

No.18.

3 Select the operating frequency.

4 Press [FM/AM] to select FM mode.

• “FM” appears.

5 Turn the SQL control to adjust squelch.

6 Repeatedly press [AGC/TONE] until “CTCSS”

appears.

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

7When 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.

7 SPECIALIZED COMMUNICATING

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 AMTOR or PacTOR to

deposit mail in a regional mailbox for forwarding. After

that, you may switch to G-TOR

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.

7 SPECIALIZED COMMUNICATING

AMTOR/ PACKET/ PACTOR/ G-TOR

/ CLOVER

Due to their error-handling capability and speed of

transmission, these modes are more efficient than

earlier forms of digital communication by machine. In

the case of G-TOR

, it was developed specifically to

handle the adverse conditions of communicating across

the solar system with spacecraft during their missions.

On most HF bands, audio frequency shift keying

(AFSK) is used. This method of modulation uses audio

tones therefore either the LSB or USB mode should be

selected. Traditionally, LSB is used similar to RTTY with

the exception of AMTOR which is normally operated

using USB.

In some countries, the licensing authorities permit F2

operation on some frequencies in the 10 meter band.

For this type of operation, select the FM mode.

Consult “MCP AND TNC” {page 62} under

“CONNECTING PERIPHERAL EQUIPMENT” if you

need installation information.

Note:

◆

For digital operation using the SSB or FM mode, switch the

Speech Processor OFF. When using the SSB mode, also select

a fast AGC setting.

◆

When selecting one of the filters (not OFF) in Menu No. 32, do

not activate the RX Equalizer via Menu No. 50; the default for

Menu No. 50 is OFF.

◆

Set Menu No. 32 to OFF for voice operation since the filters

available are too narrow for voice.

1 Select the appropriate filter bandwidth via Menu

No. 32.

• The default is OFF.

2 Select the operating frequency.

3 Press [LSB/USB] to select LSB or USB.

• For F2 operation, select FM by pressing

[FM/AM].

• If you selected one of the filters in step 1 (not

OFF), “FSK” appears with “LSB”, “USB”, or “FM”.

4 Following the instructions provided with your TNC or

MCP, enter the calibrate mode so you can generate

a mark condition.

• “RX” disappears and “TX” appears.

5 Use Menu No. 33 to select the appropriate AF input

level.

• Select a low input level so long as the ALC meter

reflects.

6 Exit the calibrate mode.

• “TX” disappears and “RX” appears.

7 Use Menu No. 34 to select the appropriate AF output

level.

• The AF control cannot be used for this

adjustment.

8 Send commands and data.

• The transceiver will briefly transmit each time it

sends your commands and data, or when it

acknowledges transmissions from other stations.

The data rates and types of modulation used for HF

Packet operation are shown below.

Note:

In some countries, F2 modulation at 1200 bps may be used

on the 10-meter band. Consult your national Amateur radio

organization to obtain band plans that specify where in each band

various modes are used.

7 SPECIALIZED COMMUNICATING

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.

SSTV FREQUENCIES

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-and-

miss 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 Tuning 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].

• “1MHz” appears.

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

MULTI/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 MULTI/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 Tuning control to select the exact

frequency.

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

• “FINE” disappears.

8 COMMUNICATING AIDS

■ 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 offset 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.

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

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].

•“FAST” appears and shows that a fast time

constant is selected.

3 To select a slow time constant, press [AGC/TONE]

again.

RX EQUALIZER

RX Equalizer changes the receive frequency

characteristics so that you can listen to received signals

with the most comfort. Use Menu No. 50 to select from

five different receive profiles including the default flat

response. Selecting any of the following items from the

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

voice with more high frequency components.

• Conventional (c):

Emphasizes by 3 dB frequencies at 600 Hz and

higher.

Note:

◆

“U” selectable in Menu No. 50 is not currently available. The

menu includes this selection because of a possible future

enhancement.

◆

The figure above is given for your better comprehension. The

actual profiles will be affected by factors such as the receive IF

filters.

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.

■ 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.

■ 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 MULTI/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.

8 COMMUNICATING AIDS

XIT (TRANSMIT INCREMENTAL TUNING)

Similar to RIT, XIT provides the ability to change your

transmit frequency by ±9.99 kHz in steps of 10 Hz

without changing your receive frequency. If the Fine

Tuning ([FINE]) function is ON, the step size is 1 Hz.

1 Press [XIT].

• “XIT” and the XIT offset appear.

2 If required, press [CLEAR] to reset the XIT offset

to0.

3 Turn the RIT/XIT control to change your transmit

frequency.

4 To cancel XIT, press [XIT].

• The transmit frequency is returned to the

frequency that was selected prior to step 1.

Note:

The frequency shift set by the

RIT/XIT

control is also used by

the RIT function. Therefore, changing or clearing the XIT offset also

affects the RIT offset.

SPEECH PROCESSOR

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.

1 Select SSB, FM, or AM mode.

2 Press [PROC] to switch the Speech Processor ON.

• “PROC” appears. The SWR meter disappears,

and the COMP meter appears.

3 Access Menu No. 15 and select the desired level of

compression.

• Selectable range is 0 dB to 25 dB in steps of 5

dB. The recommended selection and default is

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.

• “PROC” disappears. The COMP meter

disappears, and the SWR meter appears.

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

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.

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.

■ 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

CW BREAK-IN

Break-in allows you to transmit CW without manually

switching between transmit and receive modes. Two

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”).

4 Turn the MULTI/CH control to select Full Break-in or

a delay time for Semi Break-in.

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

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

is 20.

3 While keying the paddle and listening to the transmit

sidetone, turn the MULTI/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 Weighting is OFF, the

weighting is locked at 3:1.

■ Reversible Auto Weighting

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.

8 COMMUNICATING AIDS

CHANGING LOCKED-WEIGHT

Switching Auto Weighting 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 semi-

automatic 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

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.

1 Select SSB or AM mode.

2 Press [FILTER].

• The current filter selection appears.

3 Turn the MULTI/CH control to select Wide

(“FIL-WID”) or Narrow (“FIL-NAR”).

4 Press [FILTER] to complete the setting.

REJECTING INTERFERENCE

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.

Press [NB] to toggle Noise Blanker ON or OFF.

ATTENUATOR

Attenuator reduces the level of received signals. This

function is useful when interference from adjacent

frequencies is strong.

Press [ATT] to toggle Attenuator ON or OFF.

•“ATT” appears when the function is ON.

The ON/OFF setting will automatically be stored in the

current band. Each time you select the same band, the

same setting will automatically be selected.

The frequency range of each band is shown below.

PREAMPLIFIER

Switching Preamplifier OFF also may help to reduce

interference from adjacent frequencies.

Press [PRE-AMP] to toggle ON or OFF.

• “PRE-AMP” appears when the function is ON.

The ON/OFF setting will automatically be stored in the

current band. Each time you select the same band, the

same setting will automatically be selected.

The frequency range of each band is the same as for

the Attenuator. The default of Preamplifier is OFF for

the bands from 30 kHz to 7.5 MHz, and ON for the

bands from 7.5 MHz to 60.0 MHz (TS-570D: 30.0 MHz).

Note:

Switching Preamplifier OFF has the same effect as activating

the AIP function on other

KENWOOD

transceivers.

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.

■ SSB/ FM/ AM Modes

1 Select SSB, FM, or AM mode.

2 Turn the DSP SLOPE (LOW) control clockwise to

raise the low cut-off frequency, or

counterclockwise to lower the low cut-off

frequency.

Turn the DSP SLOPE (HIGH) control clockwise

to raise the high cut-off frequency, or

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.

Access Menu No. 12 and select 7.5 ms or 20 ms.

The default is 20 ms.

■

CW/ FSK Modes

1 Select CW or FSK mode.

2 Press [FILTER].

• The current filter selection appears.

3 Turn the MULTI/CH control clockwise to widen

the bandwidth, or counterclockwise to narrow the

bandwidth.

4 Press [FILTER] to complete the setting.

Depending on which bandwidth you select for the

DSP filter and which type of optional filter you install,

the wide IF filter or the narrow IF filter will

automatically be selected.

BEAT CANCEL

Beat Cancel uses an adaptive filter and attenuates more

than one cyclic interference within the receive pass

band. The adaptive filter changes its characteristics

according to the nature of the signal being received at a

given moment. You can use Beat Cancel when in SSB,

FM, or AM mode.

MEMORY FEATURES

MICROPROCESSOR MEMORY BACKUP

This transceiver uses a lithium battery to retain the user-

specified 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

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:

STORING INTO QUICK MEMORY

Each time you store a new frequency, all previously

stored frequencies are bumped to their next respective

Quick memory channel. When all five memory

channels contain frequencies, storing one more

frequency bumps the contents of memory channel 5 off

the stack (data lost).

You can store data in Quick memory only when using

VFO frequencies for both transmitting and receiving.

1 Select the frequency, mode, etc.

2 Press QUICK MEMO [M.IN].

• Each time [M.IN] is pressed, the current VFO

data is written to Quick memory.

Note:

When RIT or XIT is ON, this ON status and the offset also

will be stored.

SCAN

Scan is a useful function for hands-off monitoring of

your favorite frequencies. By becoming comfortable

with how to use all types of Scan, the monitoring

flexibility gained will increase your operating efficiency.

The transceiver provides the following types of Scan:

PROGRAM SCAN

Program Scan monitors the range between the start

frequency and the end frequency that you store in

Conventional memory channels 90 to 99. For a

refresher on how to store Program Scan limits, refer to

“STORING FREQUENCY RANGES” {page 43}.

You can select a maximum of 10 memory channels and

sequentially scan the ranges that you previously stored

in those channels. Program Scan starts with the

smallest channel number and repeats the sequence as

shown below.

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

2 Press and hold down [SCAN], then using the

numeric keys enter the second digit of each memory

channel you desire to scan, i.e. 3 for

Ch 93, 357 for Ch 93/Ch 95/Ch 97, etc.

3 Release [SCAN] to start Program Scan.

• Releasing [SCAN] before entering channel

numbers selects the channels that you selected

last time for Program Scan.

•To jump to the desired frequency while scanning,

turn the Tuning control or MULTI/CH control, or

press Mic [UP]/[DWN].

• When in a mode other than FM, turning the

RIT/XIT control clockwise decreases the scan

speed, and counterclockwise increases the

speed. “P1” to “P9” on the display show the

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.

◆

When in FM mode, Program Scan monitors rounded off

frequencies regardless of the Menu No. 05 selection.

SCAN HOLD

This function stops Program Scan for approximately five

seconds and then resumes Scan when you jump to the

desired frequency by turning the Tuning control or

MULTI/CH control, or pressing Mic [UP]/[DWN].

To use this function, access Menu No. 09, and select

ON. The default is OFF.

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}.

control slightly

counterclockwise.

◆

Starting Memory Scan switches OFF the RIT and XIT functions.

GROUP SCAN

For the purpose of Group Scan, the 100 Conventional

memory channels are divided into 10 groups, with each

group containing 10 channels. The channels are

grouped as follows:

You can select a maximum of 10 groups and

sequentially scan the channels that belong to those

groups. Group Scan starts with the smallest group

number and repeats the sequence, for example,

group3 ➞ group 5 ➞ group 7 ➞ group 3.

If you access Menu No. 11 and select ON, received

signals will also pass through the internal tuner. This

may reduce interference to the receive frequency.

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 [AT TUNE] and release it immediately.

•“AT” will appear to show that the internal tuner is in-

line (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

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:

COM

Rear panel view

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.

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.

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

Commands can be classified as shown below:

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

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}.

■

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.

Reason for Error

• Command syntax was incorrect.

• Command was not executed due to

the current status of the transceiver

(even though the command syntax

was correct).

A communication error occurred such

as an overrun or framing error during a

serial data transmission.

Receive data was sent but processing

was not completed.

Note: Occasionally this message may not

appear due to microprocessor transients in the

transceiver.
