1. FEATURES
1. Wide dynamic range
New advances in circuit design have made a 102 dB
dynamic range (500 Hz IF bandwidth) possible.
2. General coverage reception from 100 kHz
to 30 MHz
In addition to transmission and reception on all amateur
bands from 1.8 to 28 MHz, the TS-440S/44X provides
a continuous tuning general coverage receiver with a
range of 100 kHz to 30 MHz.
3. Automatic antenna tuner
The optional, built-in automatic antenna tuner will oper-
ate from 3.5 to 28 MHz.
4. All-mode operation
USB, LSB, CW, AM, FM, and AFSK modes are
provided.
5. 100% continuous duty transmit
Transmission at a 100% duty cycle is possible for rela-
tively long durations (one hour or less) in any mode,
including FM and AFSK.
6. CW full break-in
Full break-in operation is possible in the CW mode.
Rapid transmit/receive switching also makes the radio
suitable for data communications in the SSB mode,
such as AMTOR.
7. Build-in XIT
XIT (Transmitter incremental tuning) allows fine tun-
ing of the transmitter frequency.
8. Switchable IF bandwidth
The IF bandswitch allow you to tailor the bandwidth
to the operating conditions. Several selections are
provided; AUTO, W (Wide), M1 (Medium 1), M2 (Medi-
um 2) and N (Narrow). When the AUTO position has
been selected the radio will select the optimum band-
width for the selected mode of operation.
9. Switchable AGC time constant
A switch is provided to select either FAST or SLOW
AGC action.
10. All mode squelch
11. Built-in RF power/SWR meter
12. Versatile frequency control
* Accurate frequency selection is possible due to the
use of a single reference oscillator circuit.
e Continuous tuning of all frequencies thru the use of
digital VFO technology. The basic 10 Hz step tun-
ing rate is modified, according to the selected mode,
for optimum tuning speed and accuracy. An auto-
matic fast scan function is also provided.
* Dual, digital VFO's (A/B) enable crossband, cross
mode operation.
e 100-channel memory (including 10 odd-split chan-
nels) stores the frequency, band, and mode.
e° Memory scan and two programmable scan ranges.
* Direct entry of the desired frequency using the front
panel numeric keypad is also possible.
e A memory scroll function allows review of the
memory channel contents.
* Selection of the desired memory channel is possi-
ble using either the TUNING dial or microphone
UP/DOWN pushbuttons.
e° The T-F SET function is useful for split frequency
operation.
* Anoptional tone unit TU-8 may be used in conjunc-
tion with the odd-split memory channels to allow 10
meter repeater operations.
* Optional computer interface.
* Built-in long-life memory back-up battery.
e 2-color fluorescent display tube includes frequency
and other operational data.
13. Front panel control of the TUNING dial

2-2-2. Grounding
Caution:
Never use a gas pipe or electrical conduit pipe.
Notes:
1. A ground connection that is a 1/4 wavelength or
its multiple may provide a good DC ground, but it
will not provide a good RF ground.
2. A city water pipe cannot be used as a good earth
in some cases.

4. Avoid installing the equipment in front of the car
heater air outlet.
5. The standard operating voltage of the equipment
is 13.8 V. Do not operate below 12 V or over 16 V.
The transceiver can be elevated for operating con-
venience.
Caution:
Do not use the bail to carry the transceiver.
TS-440S/44xX
Making a good earth connection is important for
preventing dangers such as electric shock and for emit-
ting a high quality signal with minimum spurious radi-
ation. Bury a commercially available ground rod or
copper plate under the ground and connect it to the
GND terminal of the TS-440S/44X. A thick wire, cut
as short as possible, should be used for the connection.
To make a good earth connection, connect the GND
terminal to a metal water pipe grounded.

2-2-3. Antenna
Caution:
Protect your equipment—Use a LIGHTNING AR-
RESTOR.
Any of the common antenna systems designed for use
on the high frequency amateur bands may be used with
the TS-440S/44X provided the input impedance of the
transmission line is not outside the capability of the Au-
tomatic Antenna Tuner. The transmission line should
be coaxial cable. An antenna system which shows a
SWR (Standing Wave Ratio) of less than 1.5: 1 when
using 50 ohm coaxial transmission line, or a system
that results in a transmission line input impedance that
is essentially resistive, and between 20 and 150 ohms
will take power from the transceiver through the AT
unit.
2-2-4. Key connection
Your key should be connected as illustrated in figure
below. When using an electronic keyer, make sure that
polarity is set for positive. Always use shielded line
from the key to transceiver.
Before connecting, check that the
polarity is correct. The KEY jack
provides +5.5V. Use shielded
cable.

2-3. MOBILE
Being compact in design, this transceiver is ideal for
mobile operation. Satisfactory mobile operation is
achieved through proper power and antenna connec-
tion, and thoughtful transceiver installation and ad-
justment.
2-3-1. Mounting bracket installation
Secure the TS-440S/44X under the dashboard using
an optional MB-430 mounting bracket. As an alterna-
tive, use strapping, making sure that the TS-440S/44X
will not slip out of place while operating the vehicle.
Notes:
1. Do not install the TS-440S/44X near the heater
outlet.
2. Allow sufficient space behind the TS-440S/44X to
ensure proper ventilation.
2-3-2. Power supply connection
Cautions:
1. Turn POWER switch OFF before connecting/dis-
connecting the power cable.
2. Observe battery polarity.

Connect the TS-440S/44X power cable to the bat-
tery terminals, with consideration to current re-
quirements and noise prevention. The maximum
current drawn by the TS-440S/44X reaches to be-
tween 18 and 20A when transmitting. Therefore,
the cable should be made as short as possible, us-
ing the specified fuse. Also, determine that the
power system of the car (including the battery and
generator or alternator) will handle the increased
load of the TS-440S/44X.

Note:
The squelch threshold position will vary from mode to

NOTCH control
The NOTCH function is used to reduce or eliminate het-
erodyne, or CW type signals. The NOTCH filter will not
be effective against SSB, AM or FM type signals. To
use the control, place the NOTCH switch ON and slow-
ly rotate the NOTCH control to reduce the interference.
Normally the notch point will occur between the 11:00
and 1:00 o'clock position.
Notes:
1. The NOTCH frequency can be varied within a range
of approximately 400 to 2600 Hz.
2. When an interfering signal such as a CW station
appears, slowly rotate the NOTCH control. If you
rotate the knob too quickly you may pass right over
the notch point. Slow rotation will yield the best
results.

(2 RIT/XIT control
* RIT control
When the transmit frequency of the distant station
drifts a little bit during the QSO, but you do not wish
to alter your transmit frequency to compensate, you
may wish to make use of the RIT control function.
This control allows shifting the receive frequency
without shifting the transmit frequency. The RIT
control allows you to shift the receiver frequency
+/— 1.2 kHz. This control is also useful for pileups
when the DX station is transmitting a little above
or below his receive frequency.
Notes:
1. The RIT offset is displayed on the main display. You
can therefore preset the offset before you actually
need to use it. When you move to another station
make sure you turn OFF the RIT switch.
2. The figure at the right illustrates that the RIT dis-
play and the VFO display may not agree exactly in
all instances since the RIT and VFO tune in 10 Hz
steps. The normal resolution of the VFO is 100 Hz,
so if the RIT or VFO is turned slowly the associat-
ed display may not update immediately. You will
have to tune 100 Hz to see the display actually
change.

e XIT control
When the RIT/XIT control is rotated with the XIT
switch depressed the transmit frequency can be
varied + /— 1.2 kHz without affecting the receiver
frequency.
Pressing the switch again releases the XIT function.
(3 RF gain control
This control adjusts the gain of the receiver high-
frequency amplifier section.
For normal receiver performance, add maximum gain,
this control should be in the full clockwise position. If
you are having trouble copying the desired signal make
a note of the stations peak S-meter reading. Then, ad-
just the RF control counterclockwise, so that the meter
needle is stationary at this level. Now, all signals that
were less than the desired signal will be attenuated,
such as static noise, etc., making the completion of
the QSO easier.
If the incoming signal pegs the S-meter you can also
reduce the receiver gain by counterclockwise rotation
of the RF control. The S-meter pointer will always ad-
vance up-scale as the RF control is rotated counter-
clockwise, as a visual reminder that the gain of the
radio has been reduced.
AF gain control
Turn the inside knob to increase or decrease the
volume.
(59 SELECTIVITY switch
When an optional filter is installed, the radios passband
can be switched to one of four different bandwidths.
The switch has five positions; AUTO, N, M1, M2 and
W, that are used to select the bandwidth. The M1, and
N positions are not active until the optional filters are
installed, see the accompanying chart. This switch
should normally be set to the AUTO position. The IF
bandwidth will then be selected for optimum receiver
characteristics, according to the MODE that has been
selected. Manual override is possible by simple rota-
tion of the SELECTIVITY control.

Gi ATT (Attenuator) switch
The incoming receive signal level is attenuated by ap-
proximately 20 dB when this switch is activated.
When the incoming receive signal is very strong (20
dB over S-9), the signal should be attenuated to pre-
vent distortion of the signal, thereby stabilizing the
receiver performance. This is easily done thru the use
of the ATT switch, simply turn it ON. This control is
also useful when a strong signal is near your desired
signal, while some loss will occur to the desired signal
as well as the undesired signal the use of the attenua-
tor will sometimes allow you to complete the OSO.
61) NB (Noise Blanker) switch
When pulsating noise, such as that caused by automo-
bile ignitions is encountered, place the NB switch ON.
This will provide approximately 4O dB's of attenuation
to this interfering signal. If there is no noise present,
the switch should be in the OFF position. This switch
will not help to eliminate atmospheric or line noises,
only pulse type noise.

power supply, the PS-50 is recommended.)
3. The meter will illuminate and a frequency will ap-
pear in the display.
4. Set the BAND switches for the desired band. If you
desire to tune a frequency other than one of the
amateur radio frequencies, place the 1 MHz switch
ON. With the 1 MHz switch ON the UP/DOWN
switches will advance the frequency in 1 MHz
steps, rather than thru the amateur radio bands.
5. Select the desired MODE using one of the mode
switches.
Notes:
1. By international convention amateur radio fre-
quencies below 10 MHz utilize the LSB (Lower
Sideband) mode, and frequencies of 10 MHz
-and above use USB (Upper Sideband).
2. The TS-440S/44X automatically selects the
normal mode for you. The exact changeover
point is 9.5 MHz. You can override this selec-
tion by pressing the desired mode switch.
6. Adjust the AF gain control for the desired volume.
7. Slowly rotate the TUNING dial until the desired sig-
nal can be heard clearly.
8. The desired receive frequency can also be entered
directly by using the numeric keypad. For details
of this operation please refer to the “Direct key-
board frequency entry” section on page 13.
3-2-2. CW zero-beat operation
Zero-beat operation with a station during CW mode
operation
1. Set the RIT/XIT switches to OFF.
2. When an optional filter is not used, tune the TUN-
ING dial so that the receive beat frequency is ap-
proximately 800 Hz. You can check this by turning
the VOX OFF, and then closing your CW key. Then
by using the sidetone oscillator, and the incoming
receive signal you can zero-beat by turning the
TUNING dial until the two tones are the same fre-
quency.
3. When the YK-88C filter is used the simplest method
to use is to adjust the TUNING dial for a maximum
S-meter deflection.

Direct keyboard entry of the frequency is possible us-
ing the numeric keypad on the TS-440S/44X. This al-
lows rapid changes in frequency without the delays
encountered when using other tuning methods.
1. Select the VFO mode.
2. Press the ENT key. The display will indicate

3. Enter the desired operating frequency from Most
Significant Digit to the Least Significant Digit. You
do not have to enter trailing zeros, but you must
enter a leading zero for the frequency between 1
and 3.99999 MHz or two leading zeros for the fre-
quency between O.1 and 0.99999 MHz.
(03.500.00 MHz).
4. After the last digit has been entered press the ENT
key again to signify you want the radio to change
frequency. If you entered the frequency down to
the nearest 10 Hz a beep will sound and the radio
will automatically change to the new frequency
without the need of pressing the ENT key for the
second time.

5. If you make a mistake while entering the frequen-
cy and have not yet pressed the ENT key, or en-
tered the final digit, you may cancel the input by
pressing either the CLEAR key or standby switch.
3-2-4. AM reception
There are cases during AM broadcast reception, where
interference in noticeable when SELECTIVITY is W, but
the intelligibility is poor with the radio in the M2 posi-
tion, due to a lack of high frequency response. If this
condition occurs place the SELECTIVITY switch to M2
and rotate the TUNING dial + / — 1 kHz from the center
frequency. It should be possible to find a point where
the interference will be a little greater, intelligibility
should be improved.
Another method utilizes the execellent receiver stabil-
ity of the TS-440S/44X by selecting USB or LSB and
tuning to one of the sidebands of the AM signal. The
only disadvantage to this method is that a 5 Hz beat
tone might be detected along with the desired receive
signal.
3-3. TRANSMIT
3-3-1. SSB (USB, LSB) mode
1. Set the MODE keys to USB or LSB. By internation-
al convention frequencies below 10 MHz utilize the
LSB (Lower Sideband) mode, and frequencies
above 10 MHz use USB (Upper Sideband). The ac-
tual switchover point on the TS-440S/44X is 9.5
MHz. The TS-440S/44X will select the proper
mode when you tune to the tested frequency. You
can override this by simply Pressing the desired
mode key. A
2. Set the Meter switch to ALC.

—
3. Press the microphone PTT switch, or set the Stand-
by switch from REC to SEND.
4. Speak into the microphone and adjust the MIC gain
control so that the meter deflection does not ex-
ceed the ALC zone on voice peaks.
Note:
Adjustment using the ALC meter provides greater ac-
curacy than if you try and use the power meter for ad-
justment. Never adjust for ALC deflection above the
ALC zone, as this will cause distortion of the transmit-
ted audio signal.

° SEMI and FULL break-in
Two break-in methods are provided with the
TS-440S/44X transceiver, SEMI and FULL break-in.
With either break-in operation depressing the CW key
will cause the radio to transmit without the need for
manually switching the SEND/REC switch. The differ-
ence between FULL and SEMI break-in is that during
FULL break-in operation it is possible to listen between
dots and dashes, and that during SEMI break-in it is not.
Note:
With either SEMI or FULL break-in operation, cross
band/cross mode operation is not possible. Addition-
ally, when you are using FULL break-in operation you
should not work cross band splits, only in the same
band.
The TS-440S/44X also provides a side-tone oscillator
circuit to allow monitoring of your CW signal during
transmission.
(a) Semi-automatic break-in
Depressing the CW key will automatically place the
transceiver into the transmit mode. Transmit mode
will be maintained for a period determined by the
setting of the VOX DELAY control on the rear panel
of the transceiver, even after the CW key is
released.

Notes:
1. The FM power output may fluctuate if running less
than full output.
2. Ensure that an antenna with a low SWR is used.
The TS-440S/44X provides several protection cir-
cuits, continually loading into an antenna with a
high SWR (3 to 1 or greater) will eventually cause
damage to the final amplifiers.
3. The PWR meter reading may not be accurate with
high SWR values. Use a good antenna for the most
accurate readings.

to
recog-
.
nize the calls of stations during pile-ups.
Older transceivers required the use of an external VFO
to allow this split frequency operation. The
TS-440S/44X,
thru
the
use
of
microprocessor
controls,
effectively
provides
two
separate
VFOs
in
the
same
package.
Several
different
controls
and
switches
have
been
provided
to
increase
the
operators
convenience
when
faced
with
this
type
of
operation.
The
use
of
these controls is discussed below.
3-5-2. Split frequency
(a) A=B switch
Depressing
this
switch
causes
the
data
contained
in the inactive VFO (the VFO that is not currently
being
displayed)
to
change
to
the
same
data
con-
tained
in
the
active
VFO
(the
one
currently
dis-
played).
Both
the
frequency
and
mode
are
changed.
For
example:
VFO
A
is
set
at
7
MHz
in
LSB,
and
VFOB
is
21
MHz
in
USB.
VFO
A
is
the
active
VFO
(show
on
the
display).
Depressing
the
A
=
B
switch
will
cause
VFO
B
to
change
to
7
MHz
in
LSB.
(b) A/B switch
Allows selection of the desired active VFO. Each
time this switch is depressed the active VFO will
alternate between VFO A and VFO B.
(c) SPLIT switch
Allows the use of one VFO for transmit, and the
other for receive (Split Frequency operation). For
example: VFO A is the active VFO, and VFO B is
the inactive VFO. Depressing the SPLIT switch will
cause the TS-440S/44X to receive on VFO A and
transmit on VFO B. The mode of reception and
transmission will follow the mode contained in the
appropriate VFO memory. It is possible to work
cross band, cross mode if desired.
To avoid confusion during contest, or pile-up oper-
ations we recommend using VFO A for receive and
VFO B for transmit.
(d) T-F SET switch
Depressing this switch will allow you to rapidly set
or check the transmit frequency, during SPLIT
operations, without the need of actually trans-
mitting.
This switch is especially convenient when you are
trying to locate the transmit frequency of the sta-
tion currently in contact with the DX station, since
15

depressing this switch allows you to receive on the
transmit frequency as long as the switch is held
depressed. The TUNING dial is active when this
switch is depressed, so it is easy to change your
transmitter frequency at the same time, if neces-
sary. Releasing the switch will return you to the
original receive frequency.
3-6. MEMORY
The TS-440S/44X incorporates a convenient 100
channel memory that can be used to store and recall
commonly used frequencies. These channels can be
subdivided into 10 user-defined groups to tailor the
TS-440S/44X for optimum operation in a particular ap-
plication. You can, for instance, assign channels 10
through 19 to the 160 meter band, channels 20
through 29 to the 80 meter band, channels 30 through
39 to the 40 meter band (LSB), channels 40 through
49 to the 20 meter band (USB), channels 50 through
59 to the 15 meter band, channels 60 to 69 to the 10
meter band (FM), channels 70 through 79 to the 12
meter band, and channels 80 through 89 to various
shortwave bands. Channels 90 through 99 could then
be assigned as split frequency channels. After com-
pleting channel assignments, you can then use the con-
venient memory scan function to automatically recall
the stored frequencies on a group basis.
3-6-1. Memory Entry
1. With the TS-440S/44X in the VFO mode, select the
desired operating frequency and mode as described
in previous sections.
2. Press the M.IN switch. The radio will enter the
Memory Scroll (M.SCR) mode. The current memory
channel number (M.CH), frequency and mode will
be displayed, but the actual operating frequency
and mode will remain unchanged allowing uninter-
rupted reception.

b. Enter a two digit channel number using the nu-
meric keypad, being sure to include the leading
zero for channels OO through 09. Pressing the
CLEAR key or the standby switch before press-
ing the second digit will return you to the origi-
nal channel.
c. Use the UP/DOWN switches and/or microphone
UP/DOWN switches to scroll thru the different
memory positions.
5. When the desired memory channel is displayed,
press the M.IN key again. The current frequency
and mode will be stored, the scroll:mode will be
cancelled, and the TS-440S/44X will return to the
operating mode and frequency that was displayed
before the M.IN key was pressed initially. Note that
if RIT was selected prior to step 2, the actual fre-
quency stored will be the indicated frequency plus
or minus the RIT variable.
3-6-2. Transferring memory information to the VFO.
1. Press the VFO/M key to select the memory mode.
2. Select a channel using any of the methods dis-
cussed under the Memory Entry section.
3.
Press
the
MV
key.
The
stored
data
will
be
trans-
ferred
to
the
active
VFO
allowing
you
to
begin
tun-
ing
from
that
point.
The
TS-440S/44X
automatically
returns
to
the
VFO
mode
when
the
MEN
key
is
depressed.

agung
Notes:
1. The RIT/XIT status will be copied from the memory
to the VFO when the MV key is depressed.
2. When data is transferred from the split frequency
memory, the active VFO is loaded with the receive
data and the inactive VFO will be loaded with the
transmit data. The TS-440S/44X will then automat-
ically enter the SPLIT mode.
3. This operation will not function if no data is con-

tained in the displayed memory channel.
4. Data in the VFO is replaced by the memory data.
Memory data is not lost during this operation.
3-6-3. Transferring data between memory channels
1. With the TS-440S/44X in the memory mode, press
the M.IN key and scroll to the channel that you
want the data to be transferred to.
2. Press the M.IN key. The frequency and mode of the
memory channel that appeared before you pressed
the M.IN key will duplicated in the new channel.
3-6-4. Entering/Transferring data in the split fre-
quency channels
Separate transmit and receive frequencies may be en-
tered into memory channels 90 through 99. The proce-
dure is similar to that given for the other channels with
the following exception:
1. The active VFO frequency and mode is stored in
the receive memory, and the inactive VFO frequen-
cy and mode is stored in the transmit memory,
regardless of whether the SPLIT function is ON or
OFF.
2. The RIT offset is stored in the receive memory, and
the XIT offset in the transmit memory.
3. When data is transferred from the general memory
section into the split frequency memory section the
transmit and receive frequencies will be the same.
4. Only the receive memory will be transferred into
general memory during transfer operations from the
split memory area.
3-6-5. Clearing a memory channel
Two methods may be used to clear a memory
channel:
1. M.IN switch
Transferring information from a vacant channel, i.e. one
that has no stored information, thru the use of the M.IN
switch, as described previously in section 3-6-1 is one
method of ‘‘clearing’’ a memory channel.
2. ENT switch
Data may also be erased by depressing the ENT key
while depressing the CLEAR key.
3-6-6. Memory recall
Fixed channel type recall is possible when using the
VFO/M key to recall memory channel information. The
stored frequency cannot be changed, although the
RIT/XIT function is active.
1. Press the VFO/M key. The memory channel num-
ber, mode, and stored frequency data will be dis-
played. If a channel contains no data, only the
channel number will be displayed.

3. To return to the VFO mode, press the VFO/M key
again.
Notes:
1. RIT/XIT will be cancelled when the TS-440S/44X
is switched from the VFO mode to the memory
mode, but will be restored when the TS-440S/44X
returns to the VFO mode.
2. When the TS-440S/44X is switched from the
memory mode to the VFO mode, the VFO will be
set to the RIT/XIT variable specified when the data
was programmed in to memory.

3-7. SCAN
3-7-1. Memory scan
Memory scan operates from memory channel 00 thru
memory channel 99 at approximately 3-4 second in-
tervals. Only those memory channels with data entered
are scanned.
To initiate memory scan
1. Press the VFO/M key to select the memory mode.

2. Press the SCAN key. Scan will begin at memory
channel OO, or the lowest numbered channel con-
taining data.
3. You can stop scanning by pressing the CLEAR or
microphone PTT switch. Pressing the PTT switch
will allow you to continue scanning from the point
that you stopped, and pressing the CLEAR key will
allow you to start scanning from the beginning.
4. To resume scan press the SCAN key again.
3-7-2. Program scan
Two programmable scan ranges are provided on the
TS-440S/44X transceiver. PG.S-1 (Program Scan
range 1) utilizes memory channels O6 and 07 to specify
the upper and lower scan limits. PG.S-2 (Program Scan
range 2) utilizes memory channels 08 and O9 to specify
the upper and lower scan limits.

resume from the point you stopped.
3-8. AFSK
3-8-1. Reception
Note:
An RTTY terminal is required to receive and dis-
play/print the RTTY signal.
1. The AFSK mode utilizes the LSB carrier frequency,
which conforms to international conventions.
2. When the optional YK-88C filter is installed, the nor-
mal receiver bandwidth is 500 Hz when the SELEC-
TIVITY switch is set to the AUTO position, and the
MODE switch is in AFSK.
The accompanying diagram illustrates the relation-
ship between the carrier and the passband width.
3. The demodulated AFSK signal is sent from the
AFSK ỌUT terminal on the rear panel.
4. This completes the preparation for using the AFSK
mode.
Notes:
1. Before connecting the terminal you should review
the contents of the instruction manual provided
with that terminal unit.
2. For AMTOR reception, you should use AFSK in the
USB mode.
