Ground

(1) Antenna
Caution
Protect your equipment — Use a LIGHTNING
ARRESTER.
The type of antenna that is used will greatly affect
the performance of the transceiver. Use a properly
adjusted antenna, of good quality, to enable your
transceiver to perform at its best. The antenna input
impedance is 50 ohms. Use 50-ohm coaxial cable
such as 5D-2V or RG-213/U (RG-8A/U) for this
connection. If the antenna is far from the transceiver
the use of low loss coaxial cable, such as 5D-2V or
RG-213/U (RG-8A/U) are recommended. Match the
impedance of the coaxial cable and that of the
antenna so that the SWR is less than 1.5 to 1. The
protection circuit in the transceiver will activate if the
SWR is particularly poor (greater than 3 to 1). High
SWR values will cause the transmitter output to
drop, and may lead to TVI or BCI reports.
(2) Grounding
Warning
Never use a gas pipe or electrical conduit pipe.
(4) Key connection
Your key should be connected as illustrated in the
figure below. When using an electronic keyer, make
sure that the polarity is set for positive or direct.
Always use shielded line from the key to transceiver.

Note
| Check the polarity of the plug when you use an

Notes
1. A ground connection that is a 1/4 wavelength or
its multiple may provide a good DC ground, but
will not provide a good RF ground.
2. A city water pipe cannot be used as a good
ground in some cases.
Making a good ground connection is important for
preventing dangers such as electric shock and for
emitting a high quality signal with minimum spurious
radiation. Bury a commercially available ground rod
or copper plate under the ground and connect it to
the GND terminal. 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 grounded metal water pipe.
(3) External speaker
The TS-450S/690S includes a built-in speaker. If you
would like to use an external speaker, such as the
SP-23, it may be connected to the EXT SP jack on
the rear of the transceiver. The speaker may be any
good 8 ohm permanent magnet type speaker. The
diameter should be at least 4 inches for good audio
quality. If you plan on using a speaker other than the
SP-23 it should be equipped with a miniature phone
jack plug. (diameter 3.5 mm)

B. Front Panel
Headphone
(1) Headphones
Any low-impedance (4-16 ohms) headphone may be
used with the transceiver. Connect the headphones
to the front panel PHONES jack. (diameter 6.0 mm).
The optional HS-5 or HS-6 headphones are best
suited for use with the transceiver. Stereo type
headphones can also be used.
(2) Microphones
Any microphone with an impedance to 600. may be
used with this transceiver. The KENWOOD
microphones MC-43S (handheld), MC-60A, MC-80,
MC-85 (table-top type) are recommended.

3-2-2. Mobile Installations
Install in the safest and most accessible
location.
A. Battery Connections
Connect the power cable directly to the battery
terminals.Use of the cigarette lighter socket will lead
to poor connection, and will result in poor
performance. Pay close attention to the polarity of
the cables when connecting them to the battery.
Cautions :
1. Before installing the power cable, be sure to
remove the negative lead from the battery for
safety.
2. After installation and wiring, be sure to double
check for correct installation before
reconnecting the negative lead to the battery
terminal.
3. If the fuse opens, be sure to check that each
conductor has not been damaged by short
circuiting, etc. Then replace with a new fuse of
the same rating.
4. After completing the wiring, wrap the fuse holder
with heat resistant tape to protect against heat
and moisture.
5. Do not remove the fuse even if the power cable
is too long.
B. Ignition Noise
This transceiver has been designed to suppress
ignition noise; however, if excessive noise is
present, it may be necessary to use suppressor
spark plugs (with resistors).

C. Grounding for mobile installation
When the transceiver is installed in a car, use a
short whip antenna.
Grounding is very important when using a whip
antenna. If the grounding is poor, a good SWR value
will not be obtained.

AIP(Advanced Intercept Point) key
Use AIP when good signal reception can not be
obtained. When switched on, it reduces
interference from strong signals.
When
the
frequency
falls
below
9.5MHz,
AIP
turns
on automatically. AIP can be turned off on individual
bands below 9.5MHz by pressing the AIP key.
Note
When AIP is on, the sensitivity of the receiver is
reduced by about 10 dB in the range 100kHz to
21.5 MHz, and by about 15 dB in the range of
above 21.5MHz.
NOTCH key
When this key is ON, the notch filter is
activated.
Note
This switch is disabled during FM operation.
AGC key
Pressing this key toggles the AGC time constant
between SLOW and FAST.
FAST : For CW, FSKand data communications.
SLOW: For SSB and AM.
Note
This switch is disabled during FM operation.
@ NB 1/2 key
NB1: For pulse type noise, such as that
generated by automotive ignition systems,
select NB 1.
NB 1 will not help to eliminate
atmospheric or line noises, only pulse
type noise.
NB2: The NB2 only works on woodpecker type
noise.
Noise blanker 2 is used for long duration pulse noise,
like the “woodpecker”. To reduce “woodpecker”
radar noise interference, select NB 2 (NB 2's
effectiveness depends on the specific type of
interference). If you use NB 2 for short duration pulse
noise, the receive signal may become distorted,
making it difficult to hear.
Unfortunately no noise blanker can remove all
different types of interference; but the two noise
blankers that have been provided in the TS-
450S/690S are effective in most cases.
If there is no “woodpecker” present, turn NB2 off.
PROC key
Effective transmit power output will increase
when the PROC is turned ON during SSB mode
operations.
@) M.CH/VFO CH control
This control is used to select the desired
memory channel during Memory Channel
Operation.
This control is also used to change the
frequency in 10 kHz steps during VFO
operations.
The control is also used to select the desired
power on function you wish to change. See
section 4-11-15.
@) NOTCH control
The NOTCH function is used to reduce or
eliminate heterodyne, or CW type signals. The
NOTCH filter will not be effective against SSB,
AM or FM type signals.
@) SQL control
This control is used to eliminate atmospheric
noise, and receiver static noise during no signal
periods. Slowly rotate the control clockwise to
the point where the ambient noise just
disappears, and the speaker shuts off. This point
is known as the squelch threshold point. Now
you will only hear output from the speaker when
an incoming signal is present. For weak signal
reception this control should be fully
counterclockwise.

@) RIT/XIT control
RIT (Receiver Incremental Tuning)
The RIT control shifts the receiver frequency
without changing the transmit frequency.
When the RIT switch is ON, the RIT indicator will
light, and the receive frequency can be adjusted
by using the RIT control.
Note
When the RIT is ON the transmit frequency may
be different from the receive frequency. For
normal operation leave the RIT switch OFF. It
should be used only when necessary.
The scan speed can be changed during scanning
with the RIT control.
XIT (Transmitter Incremental Tuning)
XIT is very similar to RIT. XIT is only active in the
transmit mode. By using the XIT function it is
possible to offset the transmit frequency without
the normal loss of receiver audio that is
experienced when using the SPLIT function.
When RIT/XIT is off, the RIT/XIT display dose not
light.
The RIT/XIT step size is either 10 Hz or 20 Hz.
Please refer to Section 4-11-15 for information on
how to select the desired step size.
IF SHIFT control
Interference can be eliminated and the receive
audio quality can be adjusted.
Note
This control is disabled during FM and AM
operation.
AF gain control
Turn the knob to increase or decrease the
volume.
Clockwise rotation increases the volume and
counterclockwise rotation decreases the volume.
Note
The output level of the “Beep”, “Sidetone”
and VS-2 are not affected by adjusting of the
AF gain control.
60 RF gain control
This control adjusts the gain of the receiver
high-frequency amplifier section.
For normal receiver performance, and maximum gain,
this control should be all the way to the right. If you
are having trouble copying the desired signal make a
note of the stations peak S-meter reading. Then,
adjust the RF gain control left, so that the meter is
stationary at this level. Now, all signals that were less
than the desired signal will be attenuated, such as
static noise, etc., making reception easier.
If
the
incoming
signal
pegs
the
S-meter
you
can
also
reduce the receiver gain by moving the RF gain
control to the left. The S-meter will always advance
up-scale as the RF gain control is moved, to indicate
that the gain has been reduced.
Simultaneous use of the RF gain control and AGC
key.
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
developed from the strong disturbing signal. If this
occurs, move the RF gain control to the left so the
meter pointer remains at about the original deflection
peak and select FAST AGC.
This will reduce the unwanted AGC voltage and
permit clear reception.
Note
Turn the control fully clockwise in the FM mode.
