. The Model TS-700SP is a fully solid-state, 2 meter all-
mode amateur band transceiver, designed to provide
high quality communications an SSB, FM, AM or CW.
. A built-in digital frequency counter provides:
+ Direct frequency readout precise to 100 Hz, in seven
digits.
+ Blue fluorescent display.
+ Display of actual operating frequency, any mode.
+ Display of your actual operating frequency when us-
ing the VFO-700S external VFO.
. The TS-700SP is designed for both fixed station or
mobile operation, and has self contained AC and DC
power supplies.
. The transceiver incorporates its own built-in VFO that
continuously covers the frequency range of 144.00 to
148.00 MHz in 4 bands. Repeater operation is possible
in the 145, 146 and 147 MHz bands. The repeater
frequency is shifted at both NORMAL and REVERSE
positions of the repeater control knob.
The TS-700SP is equipped with a dual vernier tuning
control consisting of one control that provides
bandspread tuning at 25 kHz per turn, and the other
provides tuning at 100 kHz per turn. This assures max-
imum convenience when rapid tuning is needed, plus
bandspread tuning, so important in SSB reception.
11 fixed frequency crystal positions give you a total of
44 fixed channels (11 on each band).
. A noise blanker (NB) circuit is included to eliminate
pulse and ignition noise.
. For FM operation, a squelch circuit consisting of a noise
detector and Schmidt trigger is incorporated.
. The receiver RF stage uses voltage-variable capacitors
(varicaps) for tuning to minimize cross-talk and spurious
interference. It employs high “Q” antenna input circuits
(Helical Resonators) for excellent selectivity.
A FET balanced mixer is used for the pre-mixer and
heterodyne mixer for excellent spurious rejection during
transmission
The repeater frequency for transmission or reception
can be inverted (NORMAL — REVERSE) with one con-
trol. The tone burst generator permits the automatic
activation of a repeater circuit (FM-mode only).
The IF stage includes a 6-element crystal filter. Built-in
ceramic filters provide outstanding selectivity during FM
reception.

2-2. OPERATING LOCATION
As with all solid-state electronic equipment, the place
of use must be selected to avoid extremes of ambient
temperature.
A well-ventilated, dry location, where the transceiver
will not be exposed to direct sunlight, should be selected.
The TS-700SP has a heat sink on its rear panel; be sure to
install the transceiver so there is adequate clearance at the
rear and bottom. For better heat dissipation, position it
away from walls. This precaution also applies when the
transceiver is operated mobile.
When you wish to use the transceiver in a car, but sure
to provide heat dissipating clearance under and behind, and
to make proper provisions against physical shock. A rigid
mounting is advisable.
2-3. POWER SUPPLY CONNECTION
The TS-700SP is designed to operated on AC
120/220V or DC 13.8V. Switching between AC and DC is
accomplished by replacing the power cord. The DC power
cord is color coded (red for ‘’+"" and black for ‘’—"’). When
connecting the power cord, be sure to observe the following:
1. Turn off the power switch and set the standby switch to
REC position.
2. When replaceing the power cord, disconnect it from the
AC supply (or battery). When connecting the AC power
cord. Use care to prevent electrical shock. Each power
cord is equipped with a 4P plug complete with locking
tabs. When installing the plug, squeeze the tabs to en-
sure their mating with the transceiver. To remove again
squeeze the locking tabs to disengage the plug from the
transceiver, and withdraw. (See Fig. 1)
Fig. 1 Power Cord Installation & Removal
2-4. ANTENNA CONNECTION
A good antenna is important. A ground-plane or a
Yagi will give best results. The antenna should be 10 to 20
meters high and connected to the antenna terminal of your
transceiver through a coaxial cable.
Use a non-directional antenna for local com-
munications, and a directional antenna for DX.
2-5. MICROPHONE
A 500-ohm microphone is supplied with the
transceiver. Another microphone may be used providing it
matches the transceiver. For connector wiring, refer to Fig.
2 and Fig. 3
2-6. KEY
For CW operation, connect a key to the KEY jack at the
rear of the transceiver.

This meter has three functions. During reception, it serves
an as S” meter indicating the strength of received signal on
a scale graduated from 1 to 9,9 + 20dB and 9 + 40 dB
During transmission, the meter indicates RF output
The meter also functions as a center meter during FM recep-
tion when the METER switch is set to the CEN position.
@ POWER SWITCH
The power to the transceiver is turned on by setting the
power switch to the up position, and turned off at the down
position.
@ STANDBY SWITCH
The SEND position is for transmission and the REC position
for reception. With the switch in the REC position, the
transceiver automatically shifts from receive to transmit if
the microphone PTT switch is keyed
@ METER SWITCH
During FM reception, the meter functions as an “S’’ meter or
a center meter. In other receiving modes, the meter func-
tions as an “S" meter regardless of switch position.

After connecting the power cord, antenna,
microphone, key etc., set controls following Table 1.
Turn the POWER switch ON. Pilot lamps in the meter,
sub-dial pointer, band switch and FIX CH switch will light
up, indicating the transceiver is ready for operation.
Because of solid-state design, the transceiver can be put
into operation immediately after power is applied.
Next, adjust the controls according to Table 2.
Note: The DRIVE knob does not function during reception.

The foregoing settings are common to all modes of
operation. Each mode, however, calls for special techni-
ques, which will be discussed for each of the five modes.
CW Mode (How to Use the RIT)
With the RIT switch turned off, position the MAIN tun-
ing so the incoming CW signal will beat at 900 Hz. You will
then have zeroed your transmit frequency to the incoming
CW signal.
(Your transmit frequency perfectly coincides with the
transmit frequency of the other party.)
Similary, if the other party calls back with 900 Hz beat
in response to your call of the other partys transceiver is
zeroed. Should the other party call back with a beat off 900
Hz, or should you want to receive with a beat of your choice,
turn on RIT switch and adjust the RIT knob to obtain the
desired beat.
INSTRUCTIONS
nascent
Table 2
Controls Setting
AF GAIN Turn clockwise for suitable
volume.
MAIN TUNING
RF GAIN
Adjust for clear signal.
Normally, set at the extreme
clockwise position. When a signal
is very strong, turn counterclock-
wise for reduced gain.
SQUELCH
This is used for FM operation.
Turn the knob clockwise so that
receiver noise at no-signal just dis-
appears.
With the RIT switch ON, turn the
knob in either direction to vary the
receive frequency.
Refer to Page 8 “RIT” operation.
FM Mode
Set MAIN Tuning for optimum reception. By setting
the METER switch to the CEN position, the meter functions
as a center meter. Turn the MAIN dial until the center meter
pointer deflects to the center scale line while receiving the
other party's signal. In this way, your transmit frequency
will coincide with the receive frequency.
Next, set the METER switch to the ‘S” position and
the meter will indicate the strength of the incoming signal.
If, in this case, the meter pointer fluctuates in response to
the receiver audio, turn the MAIN dial a little (a few kHz) in
either direction until the meter indication is stabilized (if no
fading exists).
Since the SSB IF is part of the ‘’S” meter circuit for
FM, the “S” meter provides a logarithmic indication of FM
signal strength that is free from saturation even when the in-
put signal strength is very high. This eliminates the need for
calibration of the ‘’S’” meter for each mode of operation
Since the IF bandwidth is wide in the FM mode, a
slight deviation in frequency does not affect reception.
When transmitting, however, it is necessary to be exactly on
frequency because the other party may be crystal con-
trolled. Therefore, it is advisable that you ‘‘zero” the other
party by adjusting the MAIN tuning for a “0” indication on
the center meter.
If the ‘’S” meter continues to fluctuate or if satisfactory
audio output is not obtainable, it is very likely that the other
party is sending SSB. You can easily check this by turning
the MODE switch to USB or LSB position.
11

SSB Mode
Traditionally, USB is used. on 2m. Operating techni-
que is the same for USB or LSB.
Generally, the “Tuning” technique for SSB reception
requires a little experience.
A. Determining Received Signal Mode
(1) By using the MODE switch.
If a clear signal is heard in the FM position of the mode
switch, the signal is FM. An SSB signal will not be in-
telligable in the FM mode.
(2) By using a beat.
In the SSB mode, a beat will be heard if you are not receiv-
ing an SSB signal.
B. Dial Setting
When the received signal is found to be SSB, turn the
dial
to
the
point
where
the
sound
is
most
clear
(this
is
the
“zero” point)
If clear sound cannot be obtained it may be an indica-
tion
that
the
signal
is
LSB.
Set
the
MODE
switch
to
LSB
and retune.
Note:
1.
If
the
frequency
of
the
other
party
changes
after
the
‘zero’
point
has
been
obtained,
set
the
RIT
switch
ON
and
adjust
the
RIT
control.
2.
When
the RIT
feature
is
used,
the
receive
fre-
quency
will
be
different
from
the
transmit
fre-
quency.
Therefore,
the
RIT
must
be
set
to
“O”
or
the
RIT
switch
to
OFF
before
you
establish
another
contact.
AM Mode
AM signals cannot be demodulated in the FM mode.
They
will
be
heard
as
a
continuous
beat
in
the
SSB
mode.
Optimum
reception
of
an
AM
signal
is
obtained
by
tuning
the
transceiver
for
maximum
“S”
meter
indication.
The
bandwidth
of
the
receiver
crystal
filter
is
somewhat
narrow
for
an
AM
signal
because
this
filter
is
primarily
for
SSB
reception.
The
audio
output
may
have
some
of
its
high
fre-
quency
components
suppressed
and
hence
lack
clarity.
This
may
be
remedied
by
using
the
RIT
control
to
shift
the
receive
frequency.
Where
your
transceiver
and
that
of
the
other
party
are
both
TS-700SP,
it
should
be
noted
that,
in
AM
mode,
the
transmit
carrier
frequency
is
higher
than
the
receive
carrier
frequency
by
600
Hz.
Accordingly, you first “zero” your frequency to that of
the other party by adjusting MAIN tuning and then transmit
to which the other party will respond after possibly changing
his frequency. If he should do so, you re-match your fre-
quency
to
his
frequency
by
using
your
RIT.
(Refer
to
Fig.
5)

4-2. TRANSMISSION
Before
transmitting,
perform
all
the
necessary
procedures
for
optimum
reception.
Make
sure
that
the
fre-
quency
you
have
selected
does
not
interfere
with
other
stations.
Adjust
the
controls
(DRIVE,
MIC
GAIN
etc.)
for
good
quality
transmission.
Connect
a
50
ohm
dummy
load
or
antenna
to
the
transceiver
before
starting
to
adjust
the
various
controls.
The
use
of
a
dummy
load
is
recommended
because
this
prevents
the
possibility
of
causing
interference
to
other
stations.
Use
a
dummy
load
capable
of
dissipating
20
watts
or
more
of
RF
power.
The
tuning
procedure
should
be
completed
in
the
least
amount
of
time
possible
for
max-
imum
life
of
the
output
transistors.

CW Mode (Fig. 6)
Turn the BAND switch to the desired range. Turn the
MODE switch to the CW position. Shift the STANDBY
switch from REC to SEND and verify the meter pointer
deflects and the ON AIR indicator lights, and return to the
REC position.
Move the STANDBY switch to the SEND position and
adjust the DRIVE control for maximum deflection of the
meter pointer.
Note: Since the ALC is turned on during a full power
transmission, the drive knob provides wide tuning.
Engage the LOW-POWER switch to facilitate this
tuning operation.
The foregoing procedure should be carried out rapidly.
If a telegraph key has already been connected to the
transceiver, during adjustments the device should be set to
“key-down”. Having adjusted the transceiver as above, you
are now ready CW communication.
Adjusting Side Tone
Side tone enables monitoring the CW signal of your
station. To adjust the side tone volume, open the top cover
and turn the SIDE TONE knob for desired level. This adjust-
ment should be made in receive with the key pressed down
as the monitor circuit is activated in receive and transmit.
Other Modes
When the transceiver is properly adjusted for operation
in CW mode, it is ready for use in other modes (FM, LSB,
USB or AM). Connect the microphone and speak after shif-
ting the STANDBY switch to SEND position. Your voice will
now be transmitted.
Microphone gain adjustment for FM and SSB (USB,
LSB) can be made by the controls which become accessible
when the top lid of the transceiver is opened. Optimum set-
ting is about the mid position of their turning range (see
page 9). Microphone gain should be adjusted to assure
good quality transmission. In AM mode, optimum output
can be obtained by adjusting the AM CAR knob (see page 9)
inside the transceiver until the meter indicates anywhere
between ‘3 and “5” in transmit.
Set STANDBY switch to SEND.

PTT (Push-To-Talk) Operation
By connecting the supplied microphone or any other
microphone equipped with a PTT switch (KENWOOD’s MC-
50, etc.), the transceiver is readily used for PTT operation.
For communication, depress the PTT switch with the
STANDBY switch left in the REC position.
13

4-3. R-DX (Receive Pre-Amp)
Under normal conditions, your TS-700SP has enough
sensitivity to receive incoming signals of average strength.
For weak signals and DX communications, the pre-amp may
be used. This is turned on by the R-DX switch. The gain of
the receiver RF stage is increased by several dB, thus in-
creasing sensitivity.
When using the pre-amp, the receiver is more suscep-
table to cross-modulation and blocking from strong signals.
It is only effective on weak signals. The booster also
amplifies external noise. Sometimes turning on the noise
blanker will reduce this noise.
4-4. RIT (Receiver Incremental Tuning)
The term “RIT” is an abbreviation for “receiver in-
cremental tuning’. The RIT feature enables you to shift the
receive frequency without changing the transmit frequency.
The receive frequency may be shifted up to +2 kHz.
Note: The digital display does not show this frequency
shift.
If you want to talk to two stations that are not exact-
ly on the same frequency, proceed as follows:
1. Tune in one of the stations (RIT off).
2. Turn on the RIT and tune in the other station with
the RIT control. The RIT indicator will light.
Remember to turn the RIT off before tuning to
another frequency.
4-5. NB (Noise Blanker)
The NB (Noise Blanker) switch is used to suppress
pulse noise such as ignition noise generated by cars.
4-6. RF GAIN (Fig. 7)
This is used to adjust the receiver RF stage gain. Nor-
mally, leave it fully clockwise. For a very strong incoming
signal, turn it counterclockwise. If there is a strong signal in
the vicinity of your operating frequency, lower the RF gain to
reduce intermodulation interference.
If the RF GAIN is reduced excessively, the ‘’S’ meter
deflection will increase irrespective of incoming signal
strength, and is due to the circuit characteristic.
The RF AGC circuit is the threshold type; the “S”
meter will read correct signal strength at all time.

4-8. READING OPERATING FREQUENCIES
The digital display indicates carrier frequency in all
operating modes. The frequency displayed is your exact
operating frequency.
Note: In CW mode, the receive frequency includes the beat
frequency +900 Hz. It does not indicate RIT offset.

The TS-700SP has a tone pad input for “Auto patch”
operation. Wire the supplied miniature plug to your tone
pad as shown Fig. 9.)

4-11. 7TH DIGIT DISPLAY (FM)
The frequency display indicates to 100 Hz in the SSB,
CW and AM modes. In the FM mode, it normally indicates
to 1 kHz. The display may be extended to 100 Hz by the 7th
DIGIT DISPLAY switch (pull on).
Example: Frequency display with switch pressed in (OFF):
144.320.0|« 7digit display for other than FM mode.
144.320|+ 6-digit display for FM mode.
4-12. VOX OPERATION
The VOX (Voice Operated Transmit) automatically keys
the transmitter when you speak into the microphone with
the VOX switch ON, in the REC position. The TS-700SP will
return to the receive state when you stop talking.
CONTROL SET-UP
(1) Adjusting VOX GAIN
First, turn the VOX GAIN control clockwise to switch it
on, leaving the STANDBY switch at REC. Further, adjust the
control clockwise until the TS-700SP keys to transmit when
you speak into the microphone at normal volume.
However, excessive VOX gain results in misoperation
by ambient noise. Note that the ON AIR indicator lights in
the transmit state and goes off in the receive state.
15

(2) Adjusting the ANTI VOX
This control, located inside the cabinet (see page 9), is
used to prevent speaker sound from misoperating the VOX.
Set up the VOX GAIN as directed in Item (1), above. Adjust
the AF GAIN for typical speaker volume while receiving a
signal of moderate strength. Bring the microphone near the
speaker (20 to 30 cm), and adjust the ANTI VOX until
speaker sound will not activate the VOX. However, ex-
cessive ANTI VOX will inhibit transmit switching.
(3) Adjusting VOX DELAY
This control is used to hold the transmitter on after
VOX activation. If the hold time is too short, the TS-700SP
returns to receive whenever you pause. If too long, the
transceiver will not return to receive after speaking. Adjust
for speaking at your normal speed.
This control also sets hold time during CW semi-break-
in.
Caution: If the VOX is left “on”, the TS-700SP will
momentarily transmit when the POWER switch is
turned “‘on’’. After VOX operation turn the VOX OFF.
4-13. SEMI-BREAK-IN OPERATION
Your TS-700SP is capable of CW semi-break-in opera-
tion, in addition to the usual break-in with the STANDBY
switch. Semi-break-in uses the side tone to activate the
VOX, which switches to transmit when the key down. For
VOX operation, turn the VOX ON and set the MODE switch
to CW.
4-14. FIXED CHANNEL OPERATION
The TS-700SP has a built-in crystal oscillator circuit
for fixed channel operation. This can be used when the
transceiver is frequently operated on specific frequencies.
Examples are: FM operation on a repeater, mobile SSB
operation, and net operation.
The FIX CH knob has a total of 11 fixed channel
positions.
The crystal frequency for a fixed channel can be com-
puted from the following formula:
Crystal Oscillator Frequency for FM, AM and CW
BODDODNNNNNNNNNNNNNNNNNNANNNANNNNANNNNANNNANNNNNNNNNAD,

frequency is 8.200 MHz the operating frequency is

at this (144 MHz) frequency.
4-15. MOBILE OPERATION (DC Power)
The TS-700SP also operates from an external 13.8V
DC source for mobile operation. Operating techniques are
the same for fixed or mobile operation.
Mobile Antenna
There are many types of mobile antenna for 2 meter
use. A 1/4 wavelength whip or ground-plane or a 5/8
wavelength antenna is preferred.
Power
The TS-700SP draws about 4 amperes when working
full power. This is easily supplied by any automobile
battery. When power is supplied from a battery, it is
recommended that the automobile engine be run in order to
prevent battery discharge. See Section 2.3 for power
source information.
Note: For safe driving, it is recommended the transceiver
be operated on fixed channels.
4-16. REPEATER OPERATION
Operating Frequency
The 3-position REPEATER control functions as
follows:
* OFF Position (Simplex)
Both the transmit and receive frequencies are as indicated
on the dial.
* NORMAL Position
The dial frequency indicates the receive frequency. The
transmit frequency is 600 kHz below (145, 146 MHz
band) or above (147 MHz band) the receive frequency.
* REV Position
The dial frequency indicates the transmit frequency. The
receive frequency is 600 kHz below (145, 146 MHz band)
or above (147 MHz band) the transmit frequency.
In most cases, repeater operation is effected at the
NORMAL position of the REPEATER control. For a repeater
system whose transmit-receive frequency relationship is
reversed, repeater operation can be achieved by setting the
REPEATER control to the REV position.
Note: For 145 MHz repeater operation, an appropriate
crystal need be installed; otherwise, transmission
and reception cannot be effected at the NORMAL
and REV positions of the repeater switch.
For installing the 145 MHz repeater crystal, refer to
the instructions on page 23.
The REPEATER control has no effect on 144 MHz
band, where the transmit and receive frequencies are always
as indicated on the frequency dial. The frequency
relationship for each band is given in Table 4.
The digital frequency readout displays the frequencies
shown in Table 4 when the REPEATER is used. For exam-
ple, the readout shows 146.000.0 for both reception and
transmission in the 146 MHz band with NORMAL mode and
the VFO set to 0”. Note that the transmitting frequency is
actually 145.4 MHz though the receiving frequency is iden-
tical with the display. When switched to the REV position,
the readout shows the transmitting frequency.

Range (Sub- Dial)
*1. If the MAIN dial frequency is below 110 kHz or above 490 kHz, 145
MHz repeater operation is not recommended.
*2. If the MAIN dial frequency is less than 600 kHz, the frequency at “600
kHz shift” becomes less than 146.0 MHz which is not recommended
for repeater operation.
*3. If the MAIN dial frequency is higher than 400 kHz, the frequency at
“600 kHz shift” becomes more than 148.0 MHz. This means out of
band operation if the transmitter is operated at the NORMAL position
of the REPEATER control

Repeater Operation
The TS-700SP is designed to operate with repeater
systems of the following specification:
Frequency shift: +600 kHz
Starting system: Carrier controlled type and tone brust
type (oscillator element is optional.)
When the TONE switch is turned ON and the
transceiver is keyed in FM by the STANDBY switch or
microphone PTT switch, a tone burst signal is emitted for a
period of 0.5 to 1.0 second to bring up the repeater.
TONE Burst is easily installed by simply plugging in the
tone oscillator element (optional) into the FM IF unit (X48-
1120-20) socket.
Example: If your repeater uses an input frequency of
146.34 MHz (FM) an output frequency of 146.94
MHz (FM) and an 1800 Hz tone burst start, first in-
sert an 1800 Hz tone oscillator element into the FM
IF unit at the underside of the chassis (see Fig. 11).

clamp toward the left and lift up. The oscillator
unit will come off with the clamp.
Fig. 11 FM IF Unit (X48-1140-20)
eee
Next, set the switches and knobs as shown in Table 5.
If, at this time, the repeater is already occupied, you will
receive their signals.
If the repeater is unoccupied, you can transmit into the
repeater. If tone burst is not required, set the TONE switch
OFF. To receive the repeater input frequency, set the
REPEATER switch to REV.
If the repeater input frequency is higher than its output
frequency (this frequency relationship is reversed in 147
MHz band), set the REPEATER switch to REV and repeater
operation can be effected. If the switch is set to NORMAL,
the repeater input signal can be received.

4-17. OSCAR (Satellite) OPERATION
At present, two amateur radio communication
satellites (No. 6 and No. 7) are travelling along the orbit of
the earth. These satellites can be used as your repeater. In
satellite repeater operation, your TS-700SP will function as
the transmitter for the 2m > 10m “up-link’, or as a receiver
for the 70 cm > 2m “down-link’. Link frequencies in this
opeation are given in Table 6.
An example of 2m > 10m satellite operation using the
TS-700SP and an R-599 receiver is shown in Fig. 12.
Beside operation as shown OSCAR satellites also provide
other applications such as orbit tracking, beacons, etc.
Though you need special knowledge on operation, antenna
installation etc. With basic knowledge, you will be able to
enjoy repeater communication through the amateur
satellites with little difficulty.

5-1. BLOCK DIAGRAM
The block diagram of the TS-700SP is shown in Fig.
13. Solid-state components used in this model are: 108
transistors, 19 FET’s, 20 IC’s and 171 diodes. Circuits are
divided into individual units according to operating systems
and all units, with the exception of the band pass filters
(BPF), are wired and built on printed-circuit boards.
The receiver section operates as a single conversion
superheterodyne receiver in SSB mode and a double conver-
sion superheterodyne receiver in FM mode. The transmitter
section is single conversion and operates as a filter type unit
in SSB mode, a variable reactance frequency shift unit in FM
mode, a low power modulation system in AM, and in block
bias keying in the CW mode.
