SECTION 2. FEATURES
150 kHz - 30 MHz GENERAL COVERAGE RECEIVER
ALL MODE OPERATION
Operating mode include USB, LSB, CW, and AM, both
transmit and receive, with FM optionally available
using the FM-430 frequency modulation unit (installs easi
ly inside the transceiver). Mode selection is made
by front panel mode keys with adjacent LED indicators.
SUPERIOR RECEIVER DYNAMIC RANGE
The receiver front-end has been carefully designed to pro
vide an exceptionally wide dynamic range, through
the use of 2SK125 junction-type FET's in the RF amplifier
and balanced mixer circuits.
DUAL DIGITAL VFO's
• 10 Hz step dual digital VFO's include band and mode
information, allowing split frequency or cross-band
operation.
• A STEP switch is provided to permit tuning in 10 Hz
(10 kHz/revolution of the tuning knob), or 100 Hz (100
kHz/revolution) steps.
• An A = B switch is provided to bring the idle VFO to the
active VFO mode and frequency.
• A VFO LOCK switch is provided.
• The RIT control allows shifting the receive frequency in
either VFO or memory mode operation.
EIGHT MEMORY CHANNELS
• Each memory stores frequency, mode and band infor
mation.
• The memory CH 8 stores both a receive and a transmit
frequency for split-frequency memory operation.
• A front panel MR switch is provided to allow the opera
tor to operate each of the eight memories as an inde
pendent VFO, or as a fixed frequency.
LITHIUM BATTERY MEMORY BACK-UP
All memory and VFO information are backed-up by an in
ternal lithium battery (estimated 5 year life).
IF SHIFT CIRCUIT
The apparent IF passband may be shifted to place interfer
ing signals outside the passband, while keeping the de
sired signal optimally placed for best signal-to-noise ratio.
TUNABLE NOTCH FILTER
SPEECH PROCESSOR
The speech processor uses an audio compression ampli
fier and change in the ALC time constant, resulting in sub
stantially increased "talk-power".
ALL SOLID-STATE
The TS-430S runs 250W PEP input on CW, on 160-10
meters. In the AM mode, it runs 60W input, all
bands. In the FM mode (optional FM-430 unit installed), it
runs 1 20W input. A built-in cooling fan, plus other protec
tion circuitry assures maximum final amplifier reliability.
Both the receiver and the solid-state wide band final am
plifier requires no tuning.
NOISE BLANKER
An effective noise-blanker eliminates pulse-type interfer
ence such as ignition noise.
RF ATTENUATOR
The carefully designed receiver front-end includes a
switchable 20 dB RF attenuator for intermodulation distor
tion rejection.
VOX CIRCUIT
Both VOX and push-to-talk operation available. VOX gain,
delay and anti-VOX controls are located on top of the ca
binet, for easy adjustment. Semi-break-in operation avail
able in CW, using the built-in sidetone oscillator.
RUGGED CONSTRUCTION AND STYLING
The TS-430S is styled to enhance the appearance of any
fixed or mobile station, while providing maximum ease of
operation through a functional layout of the controls.

5.1 RECEPTION
5.1.1. RECEPTION
First connect the antenna, microphone and key. Then, set the
controls and switches referring to Fig. 5-1.
Acertain that the TS-430S is ready for operation, then turn the
POWER switch ON. The meter and digital display will illumin
ate, indicating the transceiver is in operation. The transceiver is
fully solid-state, allowing reception as soon as the POWER
switch is switched ON.
Advance the AF GAIN control clockwise until some receiver
noise is heard from the speaker. Turn the main tuning control
so the desired signal can be heard clearly.
5.1.2. RF ATT SWITCH
The input to the receive RF amplifier is attenuated approxi
mately 20 dB, providing distortion-free reception. This feature
may be used in cases of receiver overload, caused either by a
strong local signal, or during weak signal reception when a
strong adjacent signal may blank the receiver.
5.1.3. NB SWITCH
The TS-430S has a sophisticated noise blanker designed to re
duce ignition-type pulse noise. The noise blanker is particularly
important for mobile operation. When necessary, activate the
noise-blanker by depressing the NB switch ON.
5.1.4. RF GAIN CONTROL (Fig. 5-2)
For normal operation, this control should be turned fully clock
wise for maximum sensitivity. Receive sensitivity is reduced by
turning the control counterclockwise.
Adjust the RF GAIN so the S-meter does not show excessive
deflection. This minimizes noise during reception and allows
the S-meter to indicates signal peak (or a little below that
point). Noise is markedly reduced when signal is absent.

5.1.5.1. SQUELCH
To eliminate receiver noise at the no-signal condition,
slowly advance the squelch clockwise until the noise just
disappears (threshold point).
The squelch will open and the speaker will operate when a
signal is received. If the signal is weak or fades, readjust
the squelch for consistent reception.
5.1.5.2. NOTCH CONTROL
If a single tone such as a CW signal is superimposed on
the receive signal, turn the NOTCH ON and adjut the
NOTCH control to eliminate or minimize the beat signal. A
beat of approximately 900 Hz can be eliminated at the
center position of the control. The NOTCH is effective bet
ween 350 and 2600 Hz.
5.1.6. RIT CONTROL
By using the RIT (Receiver Incremental Tuning) control, the
receive frequency can be shifted by about ± 1 kHz with
out changing the transmit frequency.
If the frequency of the station you are working changes,
your receive frequency can be reset by turning the RIT
switch ON and adjusting the RIT control. Adjusting the
control clockwise increases the frequency. When first
calling another station, the RIT should be OFF, otherwise
your transmit and receive frequency will not coincide.
5.1.7. IF SHIFT CONTROL
The IF SHIFT control is used to shift the passband of the IF
filter without changing receive frequency. By turning this
control in either direction, the IF passband is shifted as
shown in Fig. 5-3.
The IF SHIFT is effective in eliminating interference when
nearby signals are superimposed on the receive signal dur
ing either SSB or CW operation. IF SHIFT does not oper
ate in the AM or FM modes.
(1) USB Mode (10 MHz and above)
Adjust the IF SHIFT control in the + direction and lower
frequencies are cut. Adjust the control in the - direction
and high frequencies are cut.
(2) LSB Mode (7 MHz and below)
Adjust the control in the + direction and higher frequen
cies are cut. Adjust the control in the - direction and low
frequencies are cut.
(3) CWMode
By using the IF SHIFT in conjunction with the RIT, tone
quality can be adjusted.
5.1.8. NAR-WIDE switch operation
For short to medium distance communication, the WIDE
position may be used for both SSB and CW operatin. For
DX (long distance) communication, the NAR position will
be an advantage in reducing interference.
This feature, in combination with the IF SHIFT control, will
provide outstanding interference rejection. The receive IF
bandwidth is 2.4 kHz in the SSB and CW wide position,
270 or 500 Hz for CW (with optional filters YK-88CN or
YK-88C) and 1.8 kHz for SSB (with optional filter
YK-88SN), in the NAR position.
*ln the AM MODE without an optional filter, both WIDE
NARROW positions are 2.4 kHz. With a YK-88A, Wide is
6 kHz, and Narrow is 2.4 kHz.
*ln transmit bandwidth is automatically WIDE.

5.2.3 PROC (processor) operation
In DX (long distance) SSB or AM operation, it may be de
sirable to increased talk-power by using the speech pro
cessor.
The speech processor in the TS-430S combines an audio
compression amplifier with changes in ALC time constant
to provide extra audio punch and increases average SSB
output power, while suppressing sideband splatter. To
activate, turn on the PROC switch, and readjust MIC gain.
Operated as described, distortion will be minimal. How
ever, tone quality will be affected. It is therefore advisa
ble to conduct normal operation with the processor dis
abled.
NOTE: ------------------------------------------------------------------------------When a high-output microphone is used, input overload
and distortion may result.
To prevent this, use an attenuator in the microphone cir
cuit as shown below, or connect a 10 - 33ki3 resistor (de
pending on the microphone used) across the microphone
input. (Mic control setting should be approximately 12 o'
clock)

5.2.1 SSB Operation
1. Set the MODE switch to SSB.
2. Meter switch to ALC.
3. Standby switch to SEND.
4. Speak into the microphone and adjust the MIC GAIN for
meter deflection within the ALC zone at signal peaks.
5. For QRP (Low Power) operation, use less MIC GAIN and
consult your external wattmeter for output level.
5.2.2 AM Operation
1. Set the MODE switch to AM and the meter switch to
1C.
2. Place the STANDBY switch to SEND and adjust the
CAR control so the meter registers approximately 2/3
its usual deflection.
3. Speak into the microphone and advance the MIC GAIN
control so the meter deflects only slightly at peaks.
Note that excessive meter deflection indicates overmo
dulation.
4. The PROC may be used to provide a more constant mo
dulation level.
5.2.4 CW Operation
1. Set the MODE switch to CW and the meter switch to
ALC.
2. Set the standby switch to SEND and adjust the CAR
control so the meter deflects within the ALC zone. If a
key is connected, it should be depressed during the ad
justment.
3. For QRP operation, adjust the Carrier Control below the
ALC point.
NOTE: -------------------------------------------------------------------------------Full power operation (more than 5 minutes at ambient
temperature of 25°C, in case of 10 MHz band, more than
30 seconds because of final efficiency), with the key kept
depressed may result in unit trouble. At this time, pay
attention to installation condition as well as ambient tem
perature, and decrease the power or operate the unit after
an interval.
5.2.5 FM Operation (With FM-430 FM unit installed)
1. Place the MODE switch to FM.
2. Place the STANDBY switch to SEND.
3. Speak into the microphone. (In the FM mode, the MIC
GAIN, CAR and meter switches are not used.)
11
5.2.6. FINAL STAGE PROTECTION
The TS-430S features a VSWR protection circuit to pro
tect the final-amplifier transistors.
Three different protection circuits are used.
1. The final-stage transistors are protected by detecting
VSWR of the antenna system and automatically low
ering transmitter output power if the VSWR is too
high.
2. When the heat-sink temperature rises, a detection cir
cuit activates a cooling fan. Under normal conditions,
this cooling fan sufficiently cools the heat sink.
3. The heat-sink temperature could rise abnormally dur
ing long transmissions, if the area adjacent to the
heat-sink is blocked. In this case, the transmission is
inhibited until the heat-sink cools to the proper tem
perature.
NOTES: ------------------------------------------------------------------------
1. If transmitter output decreases due to activation of the
protection circuit caused by high VSWR, carefully re
check and retune the antenna system.
2. When the cooling fan starts to operate, determine that
adequate air flow is possible in the heat-sink area.
• Operation of the Cooling Fan
The cooling fan operates when the heat-sink temperature
rises to approximately 50°C (122°f) and ceases to operate
when the temperature decreases to normal, approximately
40°C (104°F). The heat-sink is made of die-cast aluminum
and is actually the rear panel. It must be kept clear of sur
rounding objects to allow heat to dissipate easily.
The cooling fan is designed to operate when the heat-sink
temperature is at a specific level, regardless of whether
the unit is in transmit or receive mode.
5.2.7. MIC GAIN CONTROL (Fig. 5-5)
This control adjusts the microphone input level. When us
ing the TS-430S in a voice mode, connect a microphone
and set the STANDBY switch to SEND (an antenna or
dummy load must be connected).
For SSB operation, set the meter switch to ALC and speak
into the microphone. Adjust the MIC GAIN control so the
meter does not deflect out of the ALC zone at signal
peaks.
The TS-430S accepts either a low or high impedance mic
rophone (500 i3to 50 kO\. When using a low impedance
microphone (500 Q the MIC GAIN control should be ad
vanced slightly higher than when a high impedance micro
phone is used, while observing the ALC meter.
•
• ALC (Automatic Level Control)
The ALC monitors the transmitter final stage output to
minimize distortion in your transmitted signal. It automati
cally adjusts output to an optimum level.
Pointer should not deflect beyond ALC zone at signal peaks.

5.3 VOX OPERATION
5.3.1. VOX SWITCH
vox (voice operated transmit) is used to switch the
TS-430S into transmit mode by your voice. Place the
VOX switch ON and speak into the microphone. The
transceiver automatically switches to transmit mode (the
MIC control should be adjusted in advance as explained in
Item 5.2.7). Both the SEND switch and the MIC P.T.T.
switch are left in the REC position.
5.3.2. VOX GAIN CONTROL
This adjusts the VOX circuit sensitivity. Speak into the mi
crophone at a normal voice level and adjust the control.
Increased sensitivity allows transmission with a lower
voice level. Transceiver operating condition (receive or
transmit) can be checked by the ON AIR LED.
Note that if the control is advanced too far, the VOX circuit
may be "tripped" by ambient noise.
5.3.3. ANTI-VOX CONTROL
This prevents the VOX circuit from being false-tripped by
sound from the speaker.
Adjust the control so the VOX will not operate at the de
sired speaker volume level.
12
5.3.4. VOX DELAY CONTROL
This control adjusts the VOX circuit transmit hold time. If
the hold time is too short, the transceiver will return to re
ceive mode as soon as you stop talking into the micro
phone. This can be eliminated by advancing the control.
Adjust the control for comfortable operation at a normal
rate of speech.
5.6 CW OPERATION
For CW operation, your transmit frequency should be
"zero-beat" to the transmit frequency of the station you
are contacting. This also allows your contact to receive
your signal without having to retune his receiver. Tuning
methods are detailed in the following paragraphs.
5.4 SEMI-BREAK-IN OPERATION
The TS-430S has a built-in side-tone oscillator which,
used in conjunction with the VOX circuit, allows semi
break-in operation, besides the conventional (SEND switch
controlled) CW operation. During semi-break-in operation,
the transceiver is placed in transmit mode when the key is
depressed, and returns to receive mode when the key is
released. The VOX circuit is activated by the side-tone.
For semi-break-in operation, set the VOX switch ON and
the MODE switch to CW. Adjust the VOX GAIN to insure
that the transceiver is set in transmit mode whenever the
key is depressed. Also, adjust the VOX DELAY for the de
sired hold time.
ANTI VOX adjustment is not required.
— NOTES:--------------------------------------------------------------------
In VOX operation (semi-break-in) with VFO A/B or
transmission/reception memory (CH8), the following
combination is not possible by the circuit configur
ation.

5.5 OPERATION WITH A LINEAR
AMPLIFIER
The remote connector on the rear panel provides for inter
connection with an amplifier. See the amplifier instruction
manual to determine whether the linear requires a normal
ly opened or normally closed (during receive) relay con
tact. Connect the amplifier control line to either pin 5
(N.C.) or pin 4 (N.O. during receive). Connect the Ground
(Shield) of the Control Line to Pin 2. Connect amplifier
ALC to pin 6 of the remote connector. The TS-430S out
put is quite adequate to drive most amplifiers to full rated
output.
For full details, see section 6.8, page 22.

5.6.1. OPERATION WITHOUT AN OPTIONAL
CW FILTER
Set the IF SHIFT control to its center position and the BIT
switch OFF. Adjust the main tuning control for an 800-Hz
beat note and your transmit frequency will then coincide
with that of your contact station ("zero-beat"). During re
ception, the side-tone monitor is activated by pressing
down the key (VOX OFF). In this case, listen to the sidetone superimposed on the receive signal and adjust the
main tuning for similar side-tone and incoming CW audio
tone. By so doing, transmit frequencies will coincide.
You may now adjust the BIT for a pitch which suits your
preference. If interference is encountered, adjust the IF
SHIFT. For more convenient and effective CW operation,
use of the optional YK-88C or YK-88CN CW crystal filter
is recommended.

dicating correct tuning.
5.6.3. KEY CONNECTION
Your key should be connected as illustrated in Fig. 5-7.
When using an electronic keyer, make sure that polarity is
set for positive. Always use shielded line from the key to
transceiver.

nel selected by the M.CH switch is re
called to the VFO for tunable operation.
The mode can also be controlled when
recalled by the MR switch.
® Depress the M.CH switch, and place the M.CH switch
to the unwanted memory channel.
14
• M.CH (Memory channel) operation
The TS-430S has eight memory channels. The memory
permits input of both frequency and mode, and this data
will be permanently retained (by the built-in lithium bat
tery).
1. The M.CH switch selects the desired channel from CH
1-8.
2. When the M.IN switch is depressed, a "beep" sounds,
indicating memory input.
3. There are two recall modes for memory channel con
tents.
* Depress the M.CH switch. Any one of eight channels
can be selected by the M.CH switch as a fixed (nontunable) frequency and mode.
* Depress the MR switch. The channel designated by
the M.CH switch is recalled to the VFO for tunable oper
ation. The memory contents are not changed.
These switches are for
recalling memory.
• Memory scan operation
1. Input frequencies and modes to be scanned into the
memory channels.
2. Depress the MS switch. The channel number and fre
quency of each occupied channel is displayed. Scan in
terval is approximately 1.8 seconds per channel.
3. When the desired traffic is received during scan, de
press the HOLD switch.
4. Scan will resume by releasing the HOLD switch.
NOTES: ------------------------------------------------------------------------------
1. The channel eight transmit frequency is not scanned.
2. When memories are empty, is displayed and there is
no scan.
3. Scan is held by transmitting, and resumes when the
transceiver returns to the receive mode.
(2) Depress to initiate memory scan.
15
Program scan operation
1. Program the scanning frequency range.
2. Input the lower (or upper) frequency limit and mode into
CH 6 (using the M.IN switch). Then, input the upper (or
lower) frequency limit into CH7.
3. Depress the PG.S switch to initiate scan. The letter P
will display during program scan.
4. The scan speed is adjustable using the speed control on
the top panel, along with the STEP switch. Select the
scan speed appropriate for the selected frequency and
mode.
5. When the desired station is received and that frequency
is to be held, depress the HOLD switch. Then, adjust
the VFO for best tuning. During hold, the mode may be
temporarily changed. When Hold is released, the mode
will revert to the original programmed mode setting
after one scan cycle.
6. After the CH 7 upper (or lower) frequency limit has been
reached, a "beep" sounds and the scan repeats from
the CH 6 frequency.
NOTE: --------------------------------------------------------------------------------
1. Program scan is from CH 6 to CH 7, only.
2. During scan, only the CH 6 mode is used.
3. During scan or scan hold, a frequency can be stored
into a memory channel selected by the M.CH switch by
depressing the M.IN switch.
4. When the scan is on and the STEP switch is depressed,
the step is 100 Hz.
5. When CH 6 and CH 7 are empty, there can be no scan.
6. Scanning is stopped during transmit and resumed after
return to the receive mode.
• Memory CH 8 reception and transmission operation
1. Place the M.CH switch to "8".
2. Input the reception frequency and mode using the M.IN
switch.
3. The usual data entry "beep" is emitted as a pulse train.
Input the transmission frequency (and mode).
4. The "beep" ceases.
5. Depress the M.CH switch. "Split" frequency operation
(transmission and reception on different frequencies
are programmed into CH 8.)
NOTE: --------------------------------------------------------------------------------
1. Different modes and/or bands can also be programmed
for transmission and reception.
2. If the M.IN switch is depressed twice in succession, this
memory can be used as an ordinary memory, now hav
ing the same frequency for both transmission and re
ception.
(D Pressing this switch TWICE allows
transmission and reception on different
frequencies.

5.8 MOBILE OPERATION
Being compact in design, this transceiver is ideal for mo
bile operation. Satisfactory mobile operation is achieved
through proper power and antenna connection, and
thoughtful transceiver installation and adjustment.
5.8.1. TS-430S INSTALLATION
Secure the TS-430S under the dashboard using an option
al MB-430 mounting bracket as shown in fig. 5-8. As an
alternative, use strapping, making sure that the TS-430S
will not slip out of place while operating the vehicle.
NOTES;-------------------------------------------------------------------------------
1. Do not install the TS-430S near the heater outlet.
2. Allow sufficient space behind the TS-430S to ensure
proper ventilation.
5.8.2. CONNECTING THE POWER CABLE
When connecting or disconnecting the power cable to or
from the power connector, be sure that the power switch
is always in the "OFF" position. Observe polarity of the ca
ble. The TS-430S operates on 13.8V DC, negative
ground. Battery polarity must be correct. The power cord
is color coded.:

CAUTION: Observe battery polarity.
TS-430S
Red and White +
Black and gray -
Connect the TS-430S power cable to the battery termin
als, with consideration to current requirements and noise
prevention. The maximum current drawn by the TS-430S
reaches to between 18 and 20A when transmitting.
Therefore, the cable should be made as short as possible,
using 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-430S.
Route battery and ANTENNA leads away from all high vol
tage secondary circuits to prevent ignition noise interfer
ence.
5.8.3. MOBILE ANTENNA
(1) Antenna Installation
Use a sturdy mount for the mobile antenna since HF an
tennas are larger (and have more wind load) and are hea
vier than VHF antennas. A bumper mount is recommend
ed for general use. The ground side of the mount must be
well grounded to the car body, since the body itself func
tions as the ground plane for the mobile antenna. (Refer to
Fig. 5-8)
NOTES: ------------------------------------------------------------------------------
1. Some cars have plastic bumpers. For such cars, ground
the antenna mount to the body.
2. When tuning a newly installed antenna, use the follow
ing procedure:
• Turn the CAR control fully counter-clockwise for
minimum transmit power.
• With the transceiver in transmit mode, raise transmit
power output slowly by rotating the CAR control
clockwise. The antenna should be adjusted with
minimum power.
• Transmitting with full power is recommended only
after the antenna has been adjusted for a VSWR be
low 1.5:1.
3. Antenna installation is critical for successful mobile
operation. For further information refer to THE RADIO
AMATEUR'S HANDBOOK, RADIO HANDBOOK, or
other texts.
(2) Coaxial Cable Connection
When the antenna is mounted on the vehicles bumper, the
coaxial cable from the antenna can be routed through a
drain hole in the trunk. When the antenna is roof mounted
pass the cable between the body and door. Leave a drip-
loop at the lowest point in the cable before entry into the
vehicle to prevent water from entering the car.
(3) Antenna Adjustment
Some mobile antennas are not designed at 50-ohm impe
dance. In this case, impedance matching between the an
tenna and the coaxial cable
achieved by using an antenna matching device or coupler.
The antenna to be used should first be checked with a dip
meter to insure that it is designed for your operating band,
then the impedance matching should be checked with an
SWR meter. (See Fig. 5-9)
The VSWR should preferably be less than 1.5:1 for satis
factory operation. For antenna adjustment refer to the an
tenna instruction manual.
5.8.4. NOISE REDUCTION
In motor vehicles, noise is generated by the ignition sys
tem. Other sources of noise include the wiper and heater
motors.
Although the TS-430S is equipped with a noise blanker to
minimize ignition noise, it is imperative that some preven
tive measures be taken to reduce the noise to the lowest
possible level.
(1) Antenna location Selection
Since ignition noise is generated by the vehicles engine,
the antenna must be installed as far from the engine as
possible.
(2) Antenna Matching
In general, mobile antennas have a lower impedance than
the 50-ohm coaxial cable used to feed them, resulting in a
mismatch between the antenna and the coax. Such trou
ble can be eliminated by using an antenna tuner between
the TS-430S and the coaxial cable.

(3) Bonding
The component parts of motor vehicles, such as the en
gine, transmission, muffler system, accelerator, etc., are
coupled to one another at DC and low frequencies, but are
isolated at high frequencies. By connecting these parts
using heavy, braided ground straps, ignition noise can be
reduced. This connection is called "bonding".
(4) Use ignition Suppressor Cable or Suppressor Spark
Plugs
Noise can be reduced by using spark plugs with internal
resistors, or resistive suppressor ignition cable.
(5) Battery Power Connection
It is recommended that battery power be suppilied directly
to the TS-430S from the battery terminals.
CAUTION ---------------------------------------------------------------------------Disconnect the TS-430S before jump-starting or before
charging the battery.
(6) Battery Capacity
The power system of a motor vehicle is comprised of a
battery and an alternator (which generates power while
the engine is running) to supply current to loads or to
charge the battery.
Since the transceiver draws high current during transmit,
care should be excersised so the power system is not
overloaded. When using the transceiver, the following
points should be observed from the viewpoint of battery
maintenance:
1. Turn the transceiver OFF when the lights, heater, wip
ers and other high-draw accessories are used.
2. Avoid transceiver operation when the engine is not run
ning.
3. If necessary, use an ammeter and/or a voltmeter to
check battery condition.

5.9 FIXED STATION OPERATION
5.9.1. Power
The TS-430S requires more than 18A at 13.8 VDC when
transmitting at full power. Use the model PS-430 power
supply for fixed stations.
For HF fixed-station operation, an antenna specifically de
signed for amateur operation is recommended. Antenna
types include wire antennas, verticals, rotary beams, and
other antenna types. HF antennas are quite large and
must be installed to withstand strong wind, heavy rain,
etc.
Any antenna used with the TS-430S should be of 50-ohm
impedance and should be connected using an appropriate
coaxial cable such as RG-8/U.
Impedance matching is important. Impedance mismatch
ing will result in a high VSWR and power loss, or can
cause unwanted harmonic radiation and interference (TVI,
BCD.
The impedance match can be checked with an SWR
meter. Generally, satisfactory operation is assured when
the VSWR (Voltage Standing Wave Ratio) is less than
1.5: 1.
A rotary beam antenna is very effective for DX operation in
the 14, 21 and 28 MHz bands. (Fig. 5-11)
NOTE: -------------------------------------------------------------------------------Protect your equipment - use a lightning arrestor.

SECTION 6. ADDITIONAL INFORMATION
6.1 GENERAL INFORMATION
Your TS-430S has been factory aligned and tested to spe
cification before shipment. Under normal circumstances,
the transceiver will operate in accordance with these oper
ating instructions.
If your transceiver fails to work, contact the authorized
dealer from whom you purchased it for quick, reliable re
pair. All adjustable trimmers and coils in your transceiver
were preset at the factory and should only be readjusted
by a qualified technician with proper thest equipment.
Attempting service or alignment without factory authori
zation can void the transceiver's warranty.
6.2 INSTALLING THE OPTIONAL
FILTERS
1. Remove the power connector from the radio.
2. Using a #2 philips screwdriver, remove the top cover
(8 screws). Be careful of the VOX controls, and the

5. Using a 45W (or less) soldering pencil, clear the 6
holes for the filter, if they are filled with solder. When
installing an AM filter, first remove R16 on the IF unit,
and cut the R-129 lead on the Control unit.
6. There is no polarity to the filter. Install the filter into
its position on the IF unit. Solder the 2 mounting tabs,
and the 4 input and output pins to the circuit board.
Solder sparingly, and heat the connections only long
enough to insure a good solder joint. Don't overheat
the filter or circuit board.
7. Carefully inspect your soldering. Be certain that all
pins are actually soldered, and that you have not sol
dered across any spots on the board or between any
of the pins on the filter. Clip the pins flush to the
board.
8. Replace the IF unit in its place. Make certain no wires
will be pinched underneath the board. Replace the 7
screws for the board, plus the two heat sink screws.
Tighten the 2 side screws and replace the 2 rear
bracket screws, (See that the wire harness does not
interfere with the PG scan speed control).

6.4 HOW THE TX FINAL TRANSISTORS
ARE PROTECTED
Final transistor protection is provided by sampling the re
flected power. As the reflected power is increased (higher
SWR) transmitter drive is reduced, thus decreasing input
to the final transistors. This in turn reduces collector loss,
protecting the final transistors.

6.6 PHONE PATCH OPERATION
In an area where phone patch is legal,the PC-1 A Phone
Patch may be used with the TS-430S. Recommended set
ting are:
PC-1A RXGain 4 TS-430S VOX Gain 1
TX Gain 4
Null as necessary Mic Gain 5
Most other phone patches will work satisfactorily without
any modification to the radio, requiring only an external
speaker connection, and that the Mic line be run through
the patch.
For those operators who desire a Patch input similar to the
TS-930S, TS-520SE or TS-820S, an input connection and
terminal must be added at the Mic input preamp circuit.
Use a 100-Ki2 resistor in series, with a 10-ki2 to ground
on the input side of the 100-ki2 resistor. Use shielded line,

6.10 SSTV or AFSK operation
The TS-430S will adapt to slow scan television or AFSK
RTTY operation. For SSTV, the only cabling required are
connections between the transceiver microphone input
and the camera output, and between the speaker output
and the monitor input.
When transmitting, adjust the transmitter output so that
final input power is less than approximately 100 W, or for
approximately 1/2 of normal output power. For AFSK
operation, connect the T.U. output to the microphone in
put, and speaker output to the T.U. inpunt.
6.14 OPERATION AS A SECOND
RECEIVER
Use the REMOTE Connector. Connect Pin 3 (PTT line)
(and Pin 2, GROUND) to your XMTR control output, to
ground Pin 3 in TX. Feed the antenna through the primary
transmitter or transceiver antenna relay.
6.15 ADJUSTMENTS
1. S Meter Zero is VR2 on the IF unit.
2. S meter S-9 calibration is VR3 on the IF, set with 50//V
input at 14.1 75 MHz.
3. "Beeper" audio level is VR6 on the IF unit.
4. CW Sidetone level is VR10 on the IF unit.
5. VFO dial drag (torque) is adjustable from the small slot
ted screw accessed through the bottom cover, directly
under the VFO.
CAUTION;
The supply voltage (13.8V) always flows at the final tran
sistor collector of the TS-430 independently of the ON/
OFF position of the Power switch.
Please be sure to unplug the power cable before removing
the shield cover of the final unit.

MASTER OSCILLATOR CALIBRATION
The built-in master oscillator can be calibrated using a
WWV signal.
1. Remove the top and bottom cases.
2. Connect the second MKR terminal connector on the
Control unit and the RF unit M terminal with the
supplied calibration cable.
1. Receive WWV at 10 MHz or 1 5 MHz (with an antenna
connected.)
2. Place the Control CAL switch unit to ON.
3. The WWV signal and the marker signal may make two
beat signals (high and low). Adjust the tuning control
for zero-beat.
