(1) Antenna
Caution:
Protect your equipment—Use a LIGHTNING AR-
RESTER.
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 for this connection. If the antenna is
far from the transceiver the use of low loss coaxial
cable, such as 5D-2V is recommended. Match the
impedance of the coaxial cable and that of the anten-
na so that the SWR is less than 1.5 to 1. The protec-
tion circuit in the transceiver will activate if the SWR
is particularly poor (greater than 3 to 1). High SWR
value will cause transmitter output to drop, and may
lead to TVI or BCI reports.
(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.
Making a good earth 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 possi-
ble, 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-140S/680S
includes
a
built-in
speaker.
If
you
would
like
to
use
an
external
speaker,
such
as
the
SP-430,
it
may
be
connected
to
the
EXT
SP
jack
on
the
rear
of
the
radio.
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-430
it
should
be
equipped
with
a
miniature
phone
jack
plug.
The
internal
speaker
is
disabled
when
the
external
speaker
plug
is
inserted
into
the
receptacle.
(4) Key connection
Your
key
should
be
connected
as
illustrated
in
the
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 pro-
vides +5.5 V. Use shielded cable.

Accessories DC cable
To battery
A. Battery connection
Connect the supplied power cable with fuse directly
to the battery terminals. Connecting to the cigarette
lighter socket can cause a poor connection, and ex-
cessive voltage drop.
Cautions:
1. Before installing the power cable, be sure to
remove the negative lead from the battery for
safety.
. After installation and wiring, be sure to double
check for correct installation before reconnecting
the negative lead to the battery terminal.
If the fuse opens, be sure to check that each con-
ductor has not been damaged by short-circuiting,
etc.
Then replace with a new fuse of the same rating.
. After completing the wiring, wrap the fuse holder
with heat resistant tape to protect against heat
and moisture.
Do not remove the fuse even if the power cable is
too long.
B. Ignition Noise
The transceiver has been designed to suppress igni-
tion noise; if excessive noise is present, it may be
necessary to use suppressor spark plugs (with
resistors).

ing transmit the function of the meter is controlled
by the Meter switch @ , and provides either ALC
level, or PWR (power) readings.
@ M.CH/VFO CH (Memory channel/VFO
channel) control
This control is used to change the frequency in 10
kHz steps during VFO operations. This is convenient
when large changes in the operating frequency are
@ Q BW @d wd

@ _ Display Panel
The fluorescent display tube displays operational in-
formation such as the operating frequency, memory
channel information, and RIT information. (See page
13.)
FUNCTION keys
A/B_ : Selects VFO A or VFO B.
SPLIT: For split frequency operations; A-R, B-T (A
receive, B transmit), or B-R, A-T.
A=B : Equalizes the frequencies and modes of VFO
A and VFO B.
@ _ 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.
This control is also useful for pileups when the DX
station is transmitting a little above or below his
receive frequency.
The RIT step size is either 10 Hz or 20 Hz. Please
refer to Section 4-2-8 for information on how to
select the desired step size.
Notes:
Tt 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.
. The figure at the right illustrates that the RIT
display and the VFO display may not agree exact-
ly 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
associated display may not update immediately.
You will have to tune 100 Hz to see the display
actually change.

IF SHIFT control
The IF SHIFT control allows you to shift the IF pass-
band of the receiver, without changing the actual
center frequency of the receiver. This control is
useful when there is interference near your center
frequency.
Note:
The IF SHIFT control does not function in the AM or
F
USB mode
Interference from lower frequencies can be
reduced or eliminated by rotating the IF SHIFT
control in the @ direction. This will cause the
resulting audio frequencies to have a slightly tre-
ble response, i.e.low cut filter (low frequencies
attenuated). Interference from higher frequencies
can be reduced or eliminated by rotating the IF
SHIFT control in the © direction. This will cause
the resulting audio frequencies to sound a little
bassy, i.e.high cut filter (high frequencies at-
tenuated).
LSB mode
Interference from lower frequencies can be
reduced or eliminated by rotating the IF SHIFT
control in the @ direction. This will cause the
resulting audio frequencies to sound a little
bassy, just the opposite of the effect in the USB
mode. Interference from higher frequencies can
be reduced or eliminated by rotating the IF SHIFT
control in the © direction. This will cause the
resulting audio frequencies to appear a little on
the high side, again just the opposite of the USB
mode.
