INTRODUCTION
AND
FEATURES
1.1 KENWOOD TS-530
The TS-530 is highly sophisticated solid state Amateur
band transceiver employing only three vacuum tubes.
Operating on all Amateur bands between 1.8 and 29.7
MHz, this unit is constructed modularly. The TS-530 in-
cludes many built-in features usually found as extras on
other transceivers. Included are VOX, 25 kHz calibrator,
RIT, RF attenuator, and an effective noise blanker. The
TS-530 also includes automatic gain control (AGC), auto-
matic level control (ALC), semi-break-in CW with sidetone,
a speech processor, speaker and built-in AC power supply.
Any complicated electronic device will be damaged if
operated incorrectly, and this transceiver is no exception.
Please read all of the operating instructions before putting
your TS-530 on the air.
1.2 FEATURES
1. Interference-free DX operation
* TUNABLE NOTCH FILTER
Interference is reduced or eliminated using the built-in
notch circuit. The TS-530 uses an Audio notch filter.
* IF shift circuit
The IF SHIFT is a circuit to shift IF pass-bandwidth
without changing receive frequency. It eliminates in-
terference or adjusts receive frequency characteristic
as desired.
* NARROW/WIDE BAND WIDTH selection and optional
filters for enhanced operation. NARROW or WIDE
CW operation can be selected when using one of two
optional filters:
YK-88C (500 Hz) or YK-88CN (270 Hz)
NARROW or WIDE SSB operation can be selected
when using the optional YK-88SN (1.8 kHz) filter.
2. WARC bands
The TS-530 fully covers the 160-10m Amateur
bands, including the new WARC bands of 10, 18 and
24.5 MHz. The VFO covers at least 50 kHz above and
below each 500 kHz band. The opitonal VFO-230 ex-
ternal digital VFO covers about 100 kHz above and
below each band, for MARS and other applications.
10.
1G
. All-in-one, compact AC Power supply.
. Advanced circuit design for improved two-signal
characteristics. Cleverly designed front-end circuit
components and receive circuit system assure excel-
lent two-signal characteristics. Cross-modulation and
blocking are reduced.
. TX final unit uses 6146B’s/S2001A.
The final transmitting tubes are: two 6146B’s two
6146B's, 6146B’s/S200/AS for the TS-530SP; on
$2001A for the TS-530D.
Amplified ALC provides clear, strong signals with re-
duced cross modulation.
. Variable level noise blanker
Conventional fixed level noise blankers are sometimes
less than effective in removing pulsating noise over
weak signals or rejecting strong interference signals.
This variable level noise blanker is equipped to control
the optimum threshold level of the gate pulse mapli-
fier.
. The speech processor controls the audio compression
level and ALC time constant to increase the average
audio level and transmit power.
. XIT (Transmit Incremental Tuning) for fine adjustment
of transmit frequency independent of receive fre-
quency.
. Built-in digital display
Displays accurate frequencies to the 100 Hz order,
any band or mode.
The controls are arranged on the zinc die-cast front
panel for easy operation.
A full variety of accessory circuits are provided:
The TS-530 includes:
VOX circuit (available for Semi-Break in), Marker cir-
cuit, side-tone oscillator, selectable AGC (OFF, FAST,
SLOW) RF Attenuator, CW zero-beat circuit (in the
Tune position), HEATER switch, SCREEN GRID
switch, and built-in speaker.

2.2 OPERATING LOCATION
As with any solid state electronic equipment, the TS-530
should be kept from extremes of heat and humidety.
Choose an operating location that is dry and cool, and avoid
operating the transceiver in direct sunlight. Also, allow at
least 3 inches clearance between the back of the equip-
ment to any object. This space allows an adequate air
flow from the ventilating fan to keep the transceiver cool.
CAUTION:
Do not operate the radio in an RF Field greater than 6V RF.
Receiver damage may occur.
2.3 CABLING (See Figure 2-1.)
@ GROUND
To prevent electric shock, and reduce the possivility of TVI
and BCI, connect the transceiver to a good earth ground
through as short and heavy a lead as possible. Use ground
rods or metal cold water feedline.
NOTE:
A ground connection greater than 1/4 \ away from the
transceiver may be a good DC ground, but NOT an RF
ground.
@ ANTENNA
Connect through a 50 ohm antenna feedline to the coax-
ial connector on the rear panel.
gw KEY
lf CW operation is desired, connect a key to the KEY jack.
Use shielded line or coaxial cable.

power source capable of supplying 280 watts or more.
@ 120V AC line model (U.S.A.)
A 6A fuse is used.
If you desire operation on 220V AC or 240V AC, it is
necessary to change the power transformer connec-
tions and the fuse.
See page 27.
@ 120/220V AC line model
This version is equipped with a voltage selector switch
on the rear panel. Set the switch to your line voltage
and use the correct fuse. 120V setting requires a 6A
fuse. 220V setting requires a 4A fuse.
@ 220/240V AC line model (Europe)
This destination type is equipped with a voltage selec-
tor switch on the rear panel.
A 4A fuse should be used.
Set the switch to your line voltage and use the correct
fuse.
NOTE:
@ The 220/240V AC model is preset to 220V.
@ The 120/220V AC model is preset to 220V.
————————____ TS-530D
For fixed station operation, the unit operates either 110 or
220V AC, 50/60 Hz power source.
Check your local line voltage before operation.
The 110VAC setting requires 6A fuse.
The 220VAC setting requires 4A fuse.
Note:
The TS-530D is preset to 110V AC.

Headphones
Use headphones of 4 to 162 impe-
dance. The optional HS-4, 5, 6 or 7
headphones best suited for use with
the TS-530 Stereo-type phones can
also be used.
Microphone
Either a low or high impedance mi-
crophone (5002 to 50 kQ can be
used. The P.T.T. switch should be
isolated from the mic circuit (shown
in “A"). Use a microphone with a se-
parate switch and MIC line so both
P.T.T. and VOX are available.

2.4 MICROPHONE
Attach the microphone connector to a suitable micro-
phone, as shown in Figure 2-1. Be sure the microphone
PTT switch is separate from the microphone circuit, as
shown. It should be noted that a microphone with a 3P
plug using a common ground terminal should not be used.
The microphone input is designed for 5002 ~ 50kQ mi-
crophones. The choice of microphone is important for
good speech quality, and should be given serious considera-
tion. The crystal lattice filter in the transceiver provides all
the restriction necessary on audio response, and further
restriction in the microphone is not reqired. It is more im-
portant to have a microphone with a smooth, flat response
throughout the speech range.
Follow the microphone manufacturer's instructions for
connecting the microphone cable to the plug. With many
microphones, the push-to-talk switch must be pressed to
make microphone audio available. For VOX operation, this
unwanted feature may be eliminated, if desired, by open-
ing the microphone case and permanently connecting the
contacts which control the microphone audio.
Standard microphone sensitivity is within the range of
—50 dB to —60 dB. If a microphone having a higher sen-
sitivity is used, the ALC and compressor circuits will not
function properly. In this case, insert in the mike line an at-
tenuator as shown in Fig. 2-1c. A typical MIC gain control
setting is 12 o'clock. If you must run this control at 9 o’-
clock or less, use an attenuator.
2.5 KEY
lf CW operation is desired, connect a key to the KEY jack.
Ues shielded cable, and a standard (mono or 2P) phone
plug.
2.6 EXTERNAL SPEAKER AND
HEADPHONES
Receive audio output from the TS-530 is 1.5 watts at 4 to
16 ohms. The TS-530 has a built-in speaker jack on the
rear panel. The speaker may be an 8-ohm permanent-
magnet type, 4 inches or larger. The internal speaker is
disconnected when an external speaker is used. Head-
phones should also be 4 to 16 ohms impedance or
greater. When headphones are connected to the front-
panel PHONES jack, the speake is disabled.
2.7 GROUND
To prevent electric shock, and reduce the possibility of TVI
and BCI, connect the transceiver to a good earth ground
through as short and heavy a lead as possible.
2.8 ANTENNA
Any of the common antenna systems designed for use on
the high frequency amateur bands may be used with the
TS-530 provided the input impedance of the transmission”
line is not outside the capability of the pi-output matching
network. The transmission line should be coaxial cable.
An antenna system which shows a standing wave ratio of
less than 2:1 when using 50 or 75 ohm coaxial transmis-
sion line, or a system that results in a transmission line in-
put impedance that is essentially resistive, and between
15 and 200 ohms will take power from the transceiver
with little difficulty. If openwire of balanced type trans-
mission line is used with the antenna, a suitable antenna
tuner with balun is recommended between the transceiver
and the feedline. Methods of construction and operating
such tuners are described in detail in the ARRL Antenna
Handbook, and similar publications. For operation on the
160, 75 and 40 meter bands, a simple dipole antenna, cut
to resonance in the most used portion of the bands, will
perform satisfactorily. For operation of the transceiver on
the 10, 15 and 20 meter bands, the efficiency of the sta-
tion will be greatly increased if a good directional rotary
antenna is used. Remember that even the most powerful
transceivr is useless without a proper antenna.
CAUTION:
Protect your Equipment—Use a LIGHTING ARRESTOR.
The KENWOOD AL-2 is recommended.

1. NOTCH INDICATOR LED @®
This indicator, (light emitting diode), illuminates when the
NOTCH circuit is turned ON.
2. VFO INDICATOR
The VFO indicator illuminates when the internal VFO con-
trols transceiver operation. The indicator is not lighted
during fixed channel or remote VFO operation.
3. PROC (SPEECH PROCESSOR) INDICATOR @
This indicator, (light emitting diode), illuminates when the
PROC switch is turned ON.
4. RF ATT INDICATOR ®
This illuminates when the RF ATT is turned ON.
5. CAL SWITCH (R)
This switch energizes the built-in marker circuit.
Receive frequency can be calibrated at 25 kHz intervals
using this oscillator.
6. METER
The meter monitors five different functions, depending on
METER switch position. In receive the meter is automati-
cally an S-meter, and shows received signal strength on a
scale of O to 40 dB over SQ. In transmit, meter function
depends on the position of the METER switch, as de-
scribed below. This is an average-responding meter, NOT
peak-reading.
7. VOX SWITCH ©
The VOX circuit is readied for voice operated transmit in
SSB or semi-break-in CW.
8. VOX GAIN @
This controls sensitivity of the VOX (Voice Operated
Transmit) circuit.
9. NB SWITCH ®
With the push switch IN, the noise blanker circuit turned
ON reducing pulse-type (ignition) noise. Power-line, radar,
QRM and atmospheric “white” noises will not operate the
blanker. The noise blanker circuit operating level is adjus-
table by the noise blanker control.
10. NB LEVEL CONTROL ®
This control adjusts the noise blanker circuit operation
level according to receiving conditions or noise level.
11. AGC SWITCH ®
This controls the AGC (Automatic Gain Control) circuit:
OFF ooeeeeeeeeeee AGC disabled (no AGC).
+ Normally used for CW operation.
- Normally used for SSB operation.
12. METER SWITCH
This determines the transmit meter function:
ALC (Automatic Level Control)
Monitors internal ALC voltage, or the ALC voltage
feedback from a linear amplifier operated in conjunc-
tion with the TS-530. For SSB operation the ALC
reading for voice peaks should be within the indicat-
ed ALC range. ALC voltage adjustment is made with
the MIC control for SSB and with the CAR control for
cw.
IP (Plate Current)
In this position the meter monitors final tube plate
current. The scale is calibrated from O to 350 ma.
RF (Output Power)
This monitors relative output power of the trans-
ceiver. There is no meter scale for this position. Nor-
mally the reading should be adjusted (with the RF
METER control) for a 2/3 scale reading.
HV (High Voltage)
This position monitors the high voltage power sup-
ply. The meter scale is calibrated from O to 10, indi-
cating O to 1000 volts.
13. STAND-BY SWITCH @
This two-position lever switch selects:
REC veeeeeseereeee The transceiver is receiving unless the mi-
crophone PTT switch, or the VOX circuit is
activated.
SEND «+--+. Locks the unit in transmit.
14, VOX DELAY CONTROL @
The DELAY control adjusts the hold time for VOX or
break-in CW operation. Adjust for individual preference.
15. CAR LEVEL CONTROL @
This controls carrier level during CW operation. Adjust the
CAR level so that the ALC meter points to the center of the
ALC zone. The ALC meter should not read beyond the ALC
zone.

16. PHONES JACK ®
The headphones jack allows use of a 4 to 16 ohm or
greater headphone through a 1/4” phone plug. When
phones are used the speaker is disconnected.
17. MIC CONNECTOR @
The four pin connector allows use of a microphone with
PTT Figure 2-1 B shows plug wiring. (Page 6)
18. MODE SWITCH
The mode switch selects type of emission, and TUNE.
TUNE -00-+e--e0 This position provides reduced carrier and
shorted key line for transceiver tuning. (In-
put power to the final section is reduced to
prevent tube damage during tune-up.) Use
this position to zero-beat an incoming CW
signal.
CW vvveseseeseeeee Used for CW operation.
USB vreeeeeees Used for upper-sideband operation. Inter-
national Amateur practice dictates the use
of USB on and above the 14 MHz band.
«- Selects lower-sideband. International Ama-
teur practice dictates the use of LSB on and
below the 7 MHz band.
19. MIC GAIN CONTROL @®
This contro! adjusts microphone amplifier gain for SSB
operation. Adjust for an on-scale ALC reading on voice
peaks.
20. NAR SWITCH ®
With optional filters installed, the IF bandwidth can be se-
lected by the Narrow Switch. The bandwidth varies with
filters being used. For details, refer to Narrow Switch on
page 16.
21. PROC (SPEECH PROCESSOR) SWITCH @
This switch is used during SSB operation. Set the switch
to the ON position and the speech processor will be activ-
ated, increasing the average talk power.
22. RF ATT SWITCH ®
With this switch ON, A 20 dB attenuator is_ in-
serted in the antenna circuit, protecting the RF amplifier
and mixer from overload on strong input signals.
10
23. DIGITAL DISPLAY
The digital display indicates operating frequency to the
nearest 100 Hz.
24, ANALOG DIAL SCALE
The mono-scale permits direct analog frequency readout
over the O to 500 kHz range, graduated at 1-kHz intervals.
Opeating frequency equals the dial (in kHz) plus the BAND
switch frequency (in MHz). An additional 50 kHz both
above and below the 500 kHz range is also covered.
25. MAIN TUNING
This controls the VFO, selecting the transceiver's operat-
ing frequency. The indented knob is convenient for quick
tunig.
26. LOAD CONTROL @
This controls the loading of the network between the final
section and the antenna. Adjustment is described in Sec-
tion 4.
27. PLATE CONTROL @
This controls the plate tuning of the final amplifiers. Cali-
bration is approximate.
28. DRIVE CONTROL
This control tunes the plate tank circuit of the 12 B Y 7A
driver as well as the receiver's antenna and mixer coils. In
receive the DRIVE control is tuned for maximum sensitivity
(maximum S-meter deflection), and in transmit for a maxi-
mum ON-SCALE ALC reading. These points occur concur-
rently. Tuning for one also achieves the other.
29. RIT/XIT INDICATOR
This indicator will light when the RIT switch or XIT switch
is ON.
30. RIT/XIT CONTRL
This control allows the receive frequency, transmit fre-
quency or both to be shifted without using the main tuning
control. With the RIT switch ON, the RIT circuit is activat-
ed to shift only the receive frequency.
With the XIT switch ON, the XIT circuit is activated to shift
only the transmit frequency.
When both switches are ON, both frequencies are shift-
ed. The center (O) position equals no shift.

31. BAND SWITCH
The 10-position switch selects all Amateur bands from
1.8 to 29.7 MHz. To select the 28.5 or 29.5 MHz band,
push the + 0.5 switch ON.
Use the 10 MHz band for WWV reception.
32. +0.5 SWITCH
This switch is used in conjunction with the bandswitch.
Depress the switch with the bandswitch set to “28”, and
‘the transceiver will operate in the 28.5 MHz band.
When the bandswitch is set to “29”, the transceiver will
operate in the 29.5 MHz band. This switch has no func-
tion at any other bandswitch position.
33. AF GAIN ®
This adjusts receiver audio level. Volume increases clock-
wise.
34. RF GAIN®
This adjusts receiver RF amplifier gain. Turn fully clock-
wise for maximum gain and a correct S-meter reading.
35. POWER SWITCH
This switches all power to the transceiver.
36. HEATER SWITCH
This switch turns the three transmitting tube filaments
ON.
37. NOTCH CONTROL @®
Turn the NOTCH switch ON to activate the notch filter.
Adjust the notch frequency to null beat (carrier interfer-
ence) signals.
38. IF SHIFT CONTROL @®
During reception, the effective center frequency of the IF
crystal filter can be shifted + 1.2 kHz facilitating adjust-
ment of tone quality, or eliminating interference from
nearby frequencies. For normal operation, set to the
center detent position (click stop).
39. NOTCH SWITCH ®
This switch controls the NOTCH circuit and indicator.
40. XIT SWITCH ©
This push switch activates the XIT (Transmit Incremental
Tuning) circuit and the XIT indicator. By adjusting the XIT
control, the VFO transmit frequency can be varied + 2 kHz
without changing the receive frequency.
41. RIT SWITCH ®
This push switch activates the RIT (Receiver Incremental
Tuning) circuit, and the RIT indicator. By adjusting the RIT
control, the VFO receive frequency can be varied + 2 kHz,
without changing the transmit frequency.
If, both switches are ON, both the transmit and receive fre-
quencies will shift simultaneously.

4.1 RECEPTION (I)
NOTE:
Set the MIC and CAR controls to minimum to prevent acci-
dental transmission before tune-up is completed. The
TS-530 must be operated into 50 ohm ~ 75 ohm antenna
or dummy load with an SWR less than 2 : 1. Random
length wire antennas or light-bulb dummy loads cannot be
used.
Conventional half-wave dipoles and beam antennas
should only be used at or near their resonant frequency.
Exceeding an SWR of 2 : 1 can damage the output stage
of the transceiver.
Adjust DRIVE control for maximum deflection.

(1) Basic Procedures for Receive Operation
With a suitable antenna and microphone or key connected
to the transceiver, set the controls as shown in Fig. 4-1.
Turn the POWER switch ON. The meter, dial scale, and
VFO indicator will light, indicating the transceiver is oper-
ating. Advance the AF GAIN control clockwise until some
receiver noise is heard in the speaker. Turn the main tun-
ing dial within the frequency range of the Amateur band
chosen until a signal is heard. Tune the signal for clearest
reception,
and
then
adjust
the
DRIVE
control
for
maximum
S-meter deflection. (Fig. 4-2)
(2) WWV Reception
Set the band switch to “10” and turn the main tuning con-
trol to 10.0 MHz.
4.2 RECEPTIN (Il)
This
section
covers
operation
of
controls
and
switches
to
provide
maximum
performance
from
the
TS-530.
(1) NOTCH CONTROL
If a single tone such as a CW signal is superimposed on
the receive signal, turn the NOTCH ON and adjust the
NOTCH control to eliminate or minimize the beat signal. A
beat of approximately 1400 Hz can be eliminated at the
center position of the control. The NOTCH is effective be-
tween 350 and 2600 Hz.

(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 recep-
tion when a strong adjacent signal may blank the receiver
or pump the noise blanker.
(3) RF GAIN CONTROL
RF GAIN is controlled by changing the AGC threshold vol-
tage. Adjust the RF GAIN so the S-meter does not deflect
excessively. This also reduces noise during reception. For
normal operation, this control should be turned fully clock-
wise for maximum sensitivity.

(4) AGC (AUTOMATIC GAIN CONTROL)
Set the AGC switch to the appropriate position: Generally
for SSB, SLOW, for CW FAST, and for very weak signals,
the AGC may be turned OFF.
Simultaneous Use of the RF GAIN CONTROL and AGC
Switch
If a strong signal (such as a local station) appears in the
vicinity of the intended receive signal, the S meter may
show unusual deflection due to the AGC voltage deve-
loped from the strong disturbing signal. If this occurs, turn
the RF GAIN down so the meter pointer remains at about
the original deflection peak and turn the AGC switch OFF.
This will eliminate the unwanted AGC voltage and permit
clear reception.
(5) RIT/XIT
First set the RIT/XIT control to center, and turn the RIT
switch ON.
The RIT/XIT control allows shifting the receive frequency
by approximately +2 kHz without changing the transmit
frequency.
With the RIT switch ON, the receive frequency can be
adjusted by using the RIT control.
With both the RIT and XIT switches ON, both the transmit
and receive frequencies can be shifted.
For XIT switch operation, refer to Section 4.4 “Transmis-
sion (Il)”.
NOTE:
When the RIT is ON, transmit frequency is different from
the receive frequency. For normal operation, leave the RIT
switch OFF. It should be turned ON only when needed.
(6) IF SHIFT
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. 4-3.
The IF SHIFT is effective in eliminating interference when
the receive signal is superimposed on nearby signals
during operation in both SSB or CW mode.

frequencies are cut. Adjust the control in the (-) direction
and high frequencies are cut.
(b) 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.
(c) CW MODE
By using the IF SHIFT in conjunction with the RIT, tone
quality can be adjusted.
(7) NARROW SWITCH
In the NARROW position without optional filters no sig-
nals are received. Optional filters (CW: YK-88C,
YK-88CN, SSB: YK-88SN) for NARROW operation are
available for improved radio interference rejection. Any
two filters can be used according to your application.
When two CW filters, YK-88C and YK-88CN are used, the
WIDE position in CW mode is 0.5 kHz.
(8) NOISE BLANKER (NB)
For pulse type noise, such as generated by automotive ig-
nition systems, turn the NB switch ON. Adjusting the NB
LEVEL control varies the blanker’s threshold, eliminating
even low level noises.
If high level signal or noise is present on an adjacent fre-
quency, do not use excessive NB threshold LEVEL as it
may distort the received signal.
If you are operating near other strong signals, use the RF
ATT along with the noise blanker level control.
4.3 TRANSMISSION (I)
This section covers adjustment of the transceiver for
transmission.
Refer to Fig. 4-1 for initial transmitter switch settings. Set
the main tuning to the desired operating frequency. (Refer
to Table 4-1 for a summary of the following.)

@ PTT (Push to talk) OPERATION
By using a microphone equipped with a PTT switch, the
transceiver is ready for PTT operation. To key, depress the
PTT switch with the stand-by switch left in the REC posi-
tion.
NOTE: (For USA only)
1. Transmission is not possible with the BAND switch set to
AUX, 18 or 24.5.
2. Do not transmit when the BAND switch is set to AUX or is
midway between AUX and 1.5. Doing so will damage the
12BY7A driver tube.
4.4 TRANSMISSION (II)
To obtain maximum transmitter performance from your
TS-530 you should understand the proper operation of the
following controls and switches.
18
(1) SPEECH PROCESSOR
In
DX
(long
distance)
operation,
it
may
be
desirable
to
in-
creased
talk-power
by
using
the
speech
processor.
The speech processor in the TS-530 combines an audio
compression amplifier with changes in ALC time constant
to provide extra audio punch and to increase 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 minimum. How-
ever, tone quality will be affected. It is therefore advis-
able to conduct normal operation with the processor dis-
abled.
When a high-output microphone is used, input overload
and distortion will result. To prevent this, use an attenua-
tor in the microphone circuit as shown below, or connect a
10 — 33 kQ resistor (depending on microphone used)
across the microphone input. (“Normal mic control set-
ting should be approximately 12 O'clock).
10k — 33 kQ (depending on microphone used.)
from microphone to the MIC connecter
10 k2
(2) VOX (Voice Operated Transmit) OPERATION
Adjust the transceiver as described in the previous para-
graph. Flip the VOX switch on and while speaking into the
microphone, increase the VOX GAIN control until the VOX
relay just operates. For VOX operation it is sometimes de-
sireable to close-talk the microphone to prevent back-
ground noises from tripping the transmitter.
Check that the ALC reading for voice peaks is still within
range on the meter. If necessary, adjust the MIC control
for proper ALC reading.
If the VOX circuit is activated by speaker output, adjust the
ANTI-VOX control (on the rear panel) as necessary for
proper VOX operation.
Do not use excessive VOX or ANTI VOX gain more than
necessary to control VOX operation. If the VOX circuit
transfers between words, or holds too long, adjust the re-
lease time constant by the DELAY control.

(3) XIT
By using XIT, transmit frequency can be shifted indepen-
dent of receive frequency.
With the XIT switch ON, the XIT is controlled by the RIT/
XIT knob and transmit frequency can be shifted by about
+2 kHz. When both the RIT and XIT switches are ON,
both receive and transmit are shifted without adjusting the
main tuning.
(4) CW OPERATION (Fig. 4-9)
Tune and load the TS-530 as described in Sections 4.3.
Using shielded line, connect a key to the rear panel KEY
jack, set the MODE switch to CW, and set the stand-by
switch to SEND for transmitting.
CW transmission is automatically monitored through the
transceiver’s speaker. Sidetone audio gain can be adjust-
ed through the opening in the bottom cover.

m@ OPERATION WITHOUT AN OPTIONAL
CW FILTER
Set the IF SHIFT control to its center position and the RIT
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
reception, the side-tone monitor is activated by pressing
down the key (VOX OFF). In this case, listen to the side-
tone 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 RIT for a pitch which suits your
preference. If intereference 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.
@ OPERATION WITH CW FILTERS (OPTION)
Set the IF SHIFT to its center position and the RIT OFF.
Adjust the main tuning for maximum S-meter deflection.
Receive signal pitch will be about 800 Hz, indicating cor-
rect tuning. For optional CW filter information see page
23:
@ KEY CONNECTION (Fig. 4-12)
Your key should be connected as illustrated in Fig. 4-12.
When using an electronic keyer, make sure that polarity is
correct. Use shielded line from the key to transceiber.
NOTE:
When using an electronic keyer, set polarity of the keyer
for NEGATIVE keying.

@ SEMI-BREAK-IN OPERATION
The TS-530 has a built-in side-tone oscillator to permit se-
mi-break-in operation, besides the normal CW operation.
During semi-break-in operation, the transceiver is set in
transmit mode when the key is depressed, and returns to
receive mode when the key is released. For semi-break-in
operation, place the STANDBY switch to REC and turn the
VOX GAIN control ON. Adjust the DELAY control for your
preference.

4.5 DIGITAL DISPLAY CALIBRATION
Connect the antenna and set the BAND switch to WWV.
Turn the main tuning dial to receive 10 MHz WWV. Turn
on the calibrator. Adjust the dial until a low-frequency
beat is heard. A marker signal will be superimposed on the
WWYV signal. A double beat (two beat signals of high and
low frequencies) will now be heard. Adjust the IF shift for
low AF response. While receiving this double beat, adjust
the Standard oscillator trimmer through the reference fre-
quency adjustment access opening (on the bottom of the
TS-530) so the two beats are heard as a single beat. Re-
peat this procedure 2 or 3 times. This completes calibra-
tion of the Digital Display. After calibration turn of the
CAL switch.
