PRECAUTIONS  
7 Ventilation  
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.  
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.  
1 Power Source  
Connect this transceiver only to the power source  
described in the operating instructions or as marked  
on the transceiver itself.  
8 Water 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.  
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  
9 Abnormal Odors  
particular attention to locations near AC receptacles,  
AC outlet strips and points of entry to the transceiver.  
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.  
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.  
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  
4 Grounding and Polarization  
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.  
Do not attempt to defeat methods used for  
grounding and electrical polarization in the  
transceiver, particularly involving the input power  
cable.  
12 Periods of Inactivity  
5 Outdoor Antenna Grounding  
Disconnect the input power cable from the power  
source when the transceiver is not used for long  
periods of time.  
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.  
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.

CORRECTLY MATCHED 50 LINE  
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 antenna of good quality to let  
your transceiver perform at its best. Use a good-quality  
50 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.  
Use only as a general guide. Specifications may vary  
between cable manufacturers.

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.

1 INSTALLATION  
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.  
GROUND CONNECTION  
1
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.  
DC 13.8 V  
TS-570  
DC power supply  
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.  
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: 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.

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.

DAMAGE YOUR HEARING.  
External speaker  
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.  
TS-570  
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

OPERATING BASICS  
RADIO FREQUENCY (RF) GAIN  
SWITCHING POWER ON/OFF  
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.  
Switch ON the DC power supply, then press and hold  
down [POWER] until “HELLO” appears on the display.  
Release [POWER] when you see “HELLO”.  
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.

ADJUSTING SQUELCH  
CLR  
ENT  
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.  
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.  
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.

MENU SETUP  
WHAT IS A MENU?  
MENU ACCESS  
The following procedure explains how to check or  
change any of the Menu items.  
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.  
1 Press [MENU].  
“MENU” appears.  
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.  
2 Press [A/B] to toggle Menu A or Menu B.  
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.  
“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.

SSB TRANSMISSION  
to the receive mode.  
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.

6 BASIC COMMUNICATING  
AUTO ZERO-BEAT  
CW TRANSMISSION  
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.  
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.  
1 Press [CW TUNE] to start Auto Zero-beat.  
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}.  
“CW TUNE” appears.  
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.  
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.  
6
When matching is completed, “CW TUNE”  
disappears.  
To tune in another station so your transceiver is  
precisely on their frequency, use Auto Zero-beat.  
Refer to “AUTO ZERO-BEAT”.  
If matching is unsuccessful, the previous  
frequency is restored.  
If you wish, you can press [REV] to switch  
receive from the default upper sideband to the  
lower sideband. “R” will appear.  
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.  
3 Press [SEND].  
“RX” disappears and “TX” appears.  
No transmit carrier level adjustment is necessary.  
TX SIDETONE/ RX PITCH FREQUENCY  
Refer to “CW BREAK-IN” {page 34} for  
information on automatic TX/RX switching.  
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.  
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”.  
Receive pitch refers to the frequency of the CW note  
that you hear after tuning your receiver for maximum  
receive signal strength.  
5 Press [SEND] again to return to the receive mode.  
“TX” disappears and “RX” appears.  
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.  
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.  
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.  
21  
6 BASIC COMMUNICATING  
FM TRANSMISSION  
AM 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.  
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:  
Refer, if necessary, to “OPERATING BASICS”  
beginning on page 13 for receiving details.  
3885, 7290, 14286, 21390, and 29000~29200 kHz

No transmit carrier level adjustment is necessary.  
Refer to “VOX” {page 31} for information on  
automatic TX/RX switching.  
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.  
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.  
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.  
You may want to use the Speech Processor.  
Refer to “SPEECH PROCESSOR” {page 32} for  
details.

SPECIALIZED COMMUNICATING  
TF-SET (TRANSMIT FREQUENCY SET)  
SPLIT-FREQUENCY OPERATION  
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.  
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.  
1 Activate split-frequency operation as explained in the  
previous section.  
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)”.  
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.  
1 Press [A/B] to select VFO A or VFO B.  
tA” or “tB” appears to show which VFO is  
selected.  
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.  
2 Select the operating frequency.  
The frequency selected here will be used for  
transmitting.  
7
3 Press [A/B] to select the other VFO.  
4 Select the operating frequency.  
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.  
The frequency selected on this VFO will be used  
for receiving.  
5 Press [SPLIT].  
“SPLIT” appears.  
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.  
Pressing [A/B] reverses the receive frequency  
and the transmit frequency.  
TF-SET is also enabled while operating with the same TX/RX  
frequency (non-split).  
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.

1 Press [A/B] to select VFO A or VFO B.  
FM REPEATER OPERATION  
tA” or “tB” appears to show which VFO is  
selected.  
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.  
2 Select the operating frequency.  
The frequency selected here will be used for  
transmitting.  
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.  
3 Press [FM/AM] to select FM mode.  
“FM” appears.  
4 Press [A/B] to select the other VFO.  
To copy the frequency that you select in step 2 to  
another VFO, press [A=B] before pressing [A/B].  
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  
FM CTCSS OPERATION  
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.  
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.  
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.

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

want to contact, press [REV] to reverse the  
transceiver to the upper sideband.  
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.  
“R” appears beside “FSK”.  
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-TORTM or Clover for a  
lightning fast file transfer with a friend.  
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.  
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.  
“RX” disappears and “TX” appears.  
You may instead press [SEND] to manually

7 SPECIALIZED COMMUNICATING  
SLOW SCAN TV/ FACSIMILE  
SATELLITE OPERATION  
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.  
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.

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.

the numeric keypad can be the fastest method.  
To move up or down in frequency quickly, use the  
MULTI/CH control. Turning this control changes the  
operating frequency in 10 kHz steps.  
1 Press [ENT].  
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.  
“- - . - - - . - -” appears.  
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.  
2 Press numeric buttons [0] to [9] to enter the  
frequency you desire.  
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.  
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.  
Fine Tuning  
Pressing [CLR] cancels entry and restores  
the previous frequency.  
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.  
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.  
1 Press [FINE].  
Attempting to enter a frequency that is outside the selectable  
frequency range causes an alarm to be generated. The  
entered frequency is rejected.  
“FINE” appears.  
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.

Delay Time  
TRANSMITTING  
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.  
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.  
1 Select SSB, FM, or AM mode.  
2 Switch the VOX function ON.  
3 Press [DELAY].  
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.  
The current setting appears. The default is 50.  
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.  
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.  
“VOX” appears when the function is ON.  
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.

SPEECH PROCESSOR  
XIT (TRANSMIT INCREMENTAL TUNING)  
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.  
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

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.

MONITORING TRANSMITTED SIGNALS  
CUSTOMIZING TRANSMIT SIGNAL  
CHARACTERISTICS  
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.  
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.  
Use Menu No. 47 to select 1 to 9. The larger the  
number, the greater the monitor volume. The default is  
OFF.  
Changing Transmit Bandwidth (SSB/AM)  
Note:  
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.  
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.

CHANGING FREQUENCY WHILE TRANSMITTING  
Improves clarity by suppressing audio  
frequencies outside the normal voice frequency  
range.  
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.  
Bass boost (bb):  
Emphasizes lower audio frequencies; effective  
for a voice with more high frequency  
components.  
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.

ELECTRONIC KEYER  
CW BREAK-IN  
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.  
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.  
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.  
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.

sidetone, turn the MULTI/CH control to select the  
appropriate speed.  
4 Turn the MULTI/CH control to select Full Break-in or  
a delay time for Semi Break-in.  
The selectable range is 0 to 100 in steps of 2.  
The larger the number, the faster the speed.  
Available delay times are from 5 to 100 (50 ms to  
1000 ms) in steps of 5.  
4 Press [KEY] again to complete the setting.  
5 Begin sending.  
Note: When using the semi-automatic “Bug” function, the selected  
speed applies only to the rate that dots are sent.  
The transceiver automatically switches to the  
transmit mode.  
AUTO WEIGHTING  
When Full is selected: The transceiver  
immediately switches to the receive mode when  
the key opens.  
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.  
When a delay time is selected: The transceiver  
switches to the receive mode after the delay time  
that you have selected has passed.  
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.  
6 Press [DELAY] again.  
Note: Full Break-in cannot be used with the TL-922/922A amplifier.  
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.

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.  
5 Begin sending using the keyer paddle.  
BUG KEY FUNCTION  
The message you send is stored in memory.  
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.  
6 To complete the message storage, press [REC]  
or [CLR].  
When the memory becomes full, recording  
automatically stops.  
Note: While not operating the keyer paddle after pressing a

REJECTING INTERFERENCE  
IF SHIFT  
IF FILTER  
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.  
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 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.  
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.

receive frequency.  
“ATT” appears when the function is ON.  
You can also monitor signals trimmed off by the above  
DSP filters. Consult “PROGRAM FUNCTION

given moment. You can use Beat Cancel when in SSB,  
FM, or AM mode.  
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

MEMORY FEATURES  
STORING DATA IN MEMORY  
MICROPROCESSOR MEMORY BACKUP  
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:  
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.  
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.  
CONVENTIONAL MEMORY  
Note: When RIT or XIT is ON, the frequency that includes the RIT  
or XIT offset will be stored.  
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.  
Simplex Channels

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.

PROGRAM SCAN  
Note:  
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}.  
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.  
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.  
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.

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:  
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.

Transferring Data  
QUICK DATA TRANSFER  
The TS-570 transceiver works as the Master  
sending data to the Slave transceiver.  
This transceiver has the capability to quickly and  
conveniently transfer the receive frequency and mode to  
another compatible transceiver. Compatible  
transceivers include:  
1 Switch ON the Transfer function on each  
transceiver.  
• TS-570S/570D • TS-850S  
On the TS-570, access Menu No. 36 and  
select ON. For the compatible transceiver,  
check the instruction manual that came with  
the transceiver.  
• TS-870S  
• TS-690S  
• TS-450S  
• TS-950SDX  
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.  
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,

In addition to a compatible transceiver, the following  
equipment is required:  
Note: If the Master has RIT switched ON, the offset frequency  
is added to the receive frequency to be transferred.  
Transfer to TS-570 or TS-870S:  
Receiving Data  
One cross-wired cable  
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.  
This cable must have a 9-pin RS-232C female  
connector at both ends.

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

Note:  
AUTOMATIC ANTENNA TUNER  
The internal tuner will not tune outside the authorized transmit  
limits of Amateur bands.  
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.  
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.  
1 Select the transmit frequency.  
2 Press [ANT] to select ANT 1 or ANT 2.  
Tuning still may continue when the SWR meter indicates 1:1.  
This happens because of the tuning algorithm, and does not  
indicate a malfunction.  
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.  
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.  
3 Press [AT TUNE] and release it immediately.  
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.  
“AT” appears to show that the internal tuner is in-  
line (not bypassed).  
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).  
4 Press [AT TUNE] for more than one second.  
CW mode is automatically selected and tuning  
starts.  
Press [AT TUNE] and release it immediately.  
“AT” will appear to show that the internal tuner is in-  
line (not bypassed).  
“AT” blinks, and “TX” and “CW” appear.  
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 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.

Voice 1:  
VFO or memory channel frequencies are announced  
beginning with the 10 MHz digit and continuing  
through to the 10 Hz digit. If the memory channel  
has no data stored, “open” is announced. For the  
MHz decimal point, “point” is announced. For the  
kHz decimal point, a short pause (200 ms) is made.  
A 200 ms pause also is made between the channel  
number and the frequency.  
Menu numbers and their settings are announced  
with a short pause (200 ms) between the menu  
number and the setting.  
Note: If operating a button or a control changes the contents of the  
display while an announcement is in progress, the announcement is  
interrupted.  
Voice 2:  
Peak readings for the S-meter are announced, for  
example, “S5” or “20dB”.

15 CONNECTING PERIPHERAL EQUIPMENT  
MCP AND TNC  
Use the ACC 2 connector to connect the input/output lines from a Terminal Node Controller (TNC) for Packet operation,  
a Multimode Communications Processor (MCP) for operation on Packet, PacTOR, AMTOR, G-TORTM, or FAX, or from  
a Clover interface. Also use the ACC 2 connector to connect SSTV and phone patch equipment.  
Connect the TNC or MCP to the ACC 2 connector using a cable equipped with a 13-pin DIN plug.  
Connecting the TNC or MCP to a personal computer or dumb terminal requires an RS-232C cable.  
Note:  
Do not share a single power supply between the transceiver and the TNC or MCP. Keep as wide a separation as possible between the  
transceiver and the computer as practical to reduce noise-pickup by the transceiver.  
The output voltage of Pin No. 6 (SMET) is not 0 V even when no signal is present. In addition, the output voltage differs between FM  
(approx. 2.8 ~ 3.8 V) and other modes (approx. 0.5 ~ 3.8 V). When connecting this pin to peripheral equipment such as a personal computer,  
the input impedance of that equipment must be higher than 1 M. If you connect to equipment having lower impedance, the S-meter will not  
give accurate readings.

TROUBLESHOOTING  
The problems described in this table are commonly encountered operational malfunctions. These types of difficulties  
are usually caused by improper hook-up, accidental incorrect control settings, or operator error due to incomplete  
programming. These problems are usually not caused by circuit failure. Please review this table, and the appropriate  
section(s) of this instruction manual, before assuming your transceiver is defective.  
Note:  
Due to frequency relationships of some circuits in this transceiver, beat tones may be heard on the following frequencies: 10.000 MHz,  
20.000 MHz and 30.000 MHz. This is not a fault.  
Placing a powered handy transceiver near this transceiver may cause noise in this transceiver.

APPENDIX  
CONTROL OPERATION  
APPENDIX: COM CONNECTOR PROTOCOL  
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.  
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:  
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.  
COM  
Only 3 lines are required theoretically for control of the  
transceiver via the computer:

Rear panel view  
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.

Transmit data  
RXD  
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.

Parameters  
COMPUTER CONTROL COMMANDS  
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.  
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  
;
When configuring parameters, be careful not to  
make the following mistakes.

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.  
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:  
Error Messages  
In addition to the Answer command, the transceiver  
can send the following error messages.  
“FA00007000000;”  
(Set command)  
Error  
To read the frequency of VFO A, the following  
command is sent from the computer to the  
transceiver:  
Reason for Error  
Message  
?;  
Command syntax was incorrect.  
“FA;”  
(Read command)  
Command was not executed due to  
the current status of the transceiver  
(even though the command syntax  
was correct).  
When the Read command above has been sent, the  
following command is returned to the computer:  
“FA00007000000;”  
(Answer command)  
Note: Occasionally this message may not  
appear due to microprocessor transients in the  
transceiver.  
Note:  
Do not use the control characters 00 to 1Fh since they are either  
ignored or cause a “?” answer.  
E;  
A communication error occurred such  
as an overrun or framing error during a  
serial data transmission.  
Program execution may be delayed while turning the Tuning  
control rapidly.  
Receive data is not processed if the frequency is entered from  
the keypad.  
O;  
Receive data was sent but processing  
was not completed.  
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}.
