GENERAL/CIRCUIT DESCRIPTION
General
A block diagram of TS-5205 is shown on page 5. The unit is
composed of a transmitter and a receiver, each being of the
filter type double-conversion system. The receiver has a
first IF section (8.895 MHz to 8.295 MHz) and a second IF
section (3.395 MHz). The unit contains a number of ad-
vanced accessory circuits and devices, such as a speech pro-
cessor, RF NFB, 1.8 MHz and AUX bands, RF ATT, digital
display terminal (for connection of DG-5 option and phone
patch terminal, in addition to other circuits which are found
in conventional transceivers.
Circuit Description
Transmitter Section
The microphone signal is fed to the generator unit (refer to
paragraph “Generator Unit” for operation of generator
unit) and. is amplified by the MIC amplifier. The signal is
then converted to aDSB (Double Side Band) signal of 3.395
MHz and fed to the IF unit. The signal passes through the
crystal filter and becomes a SSB signal. |
The IF signal is mixed with the VFO signal by the 1st mixer
and becomes the 2nd IF frequency of 8.895~8.295 MHz.
This signal passes through the BPF and is fed to the RF unit.
The signal is then converted to the transmit frequency, 1.8~
28 MHz by Q1 3SK41(L) and is voltage amplified by the
driver tube V1 12BY7A to drive the final tubes S2001A
which deliver RF power to the ANT circuit.
Receiver Section
The receive signal of 1.828 MHz from the ANT terminal is
converted to a 1st IF of 8.895~8.295 MHz through the RF
unit and is fed to the IF unit. The signal passes through
the BPF of the IF and is mixed with the VFO signal by 09
that it becoming the 2nd IF frequency of 3.395 MHz. The
signal then passes through the NB, returns to the IF, pass-
ing through the crystal filter, and is amplified before being
fed to the generator unit. Finally, the signal is fed to the
BD (balance detector) where it is converted to an AF signal.
The AF signal is fed to the AF unit where it is amplified by
Q1~4 to drive the speaker. |
1. Carrier Unit (X50-0009-01)
This circuit functions as .a carrier oscillator for the generator
“during transmission, and as а BFO for the ring detector
during reception. The oscillator circuit QT (25C460B) is of
the Pierce B-E type; 02 (2SC460B) functions as a buffer
amplifier to provide stabilized output. Selection of oscilla-
tion frequency is accomplished by diode switch D1-D4
(191555 X 4). |
When forward biased the diode internal resistance become
low and an oscillator circuit is completed. Without forward
bias, the diode resistance becomes high, and the crystal is
_ disconnected, stopping oscillation. Frequencies are 3396.5
kHz for USB, 3393.5 kHz for LSB, and 3394.3 kHz (receive)
and 3395.0 kHz (transmit) for CW.
2. Generator Unit (X52-1090-00)
This is the heart of the SSB transmitter, generating DSB
signals during transmission. Voice signals fed to micro-
phone are amplified by 03 (25C1000GR), 05 (25C733Y)
and 06 (2SC733Y) and then fed to the ring modulator
(D1-D4), which suppresses the carrier component, passing
only the DSB signal. The signal is amplified by the FET
buffer amplifier Q1 and applied to the IF. The unwanted
side band and carrier contained in DSB signals are further
suppressed by the crystal filter in the IF unit to obtain a
SSB signal. During CW operation, a DC voltage unbalances
the ring modulator to obtain carrier output.
The processor is controlled by a switch on the front panel.
Operating as a compressor circuit, the output of O3 is further
amplified by 04 (2SC1000GR), 08 (25C30-0), 09 (2SC-
733Y) and 010 (25C733Y) and is fed to O5 through the
diode switch controlled by the processor switch. The out-
put of 010 is phase inverted by 011 (25C945A) and recti-
fied by a bridge rectifier consisting of 4 diodes. This signal
is DC amplified by 012 (25C945R) to control the FET
attenuator 07 (25K30-0) which utilizes pinch-off voltage.
The required time constant is obtained at the output of
012; in practice, 14 dB compression is obtained at 10 mV
MIC input.
The MIC gain control is provided on the input side of O5,
so MIC gain can be set as desired independent of the proces-
sor switch position.
The unit also includes a receive ring demodulator and a.
transistor switching circuit 02 (25C460B) which disconnects
carrier to the transmit ring modulator during reception.

CIRCUIT DESCRIPTION
3. RF Unit (X44-1200-00)
Among the units contained in the TS-520S, this unit has the
greatest number of functions. It is composed of a trans-
mitter section, receiver section, ALC circuit and a bias con-
trol circuit.
WWV Receiving Section
The 15MHz WWV signal passes through the diode switch.
interlocked with the band switch and is RF amplified by ©
FET.05 (2SK19GR) after being stepped up by T5. This
signal is then converted into the 1st IF signal of 8.895 MHz
by 04 and fed to the band pass filter T2. The 1st local
oscillator circuit is an overtone circuit consisting of 08
whose power source voitage is stabilized by D3.
During. WWV reception, power source voltage (14V) is not
applied to the transmitter 2nd mixer ОТ, receiver 1st mixer
O2 and the 1st local oscillator circuit.
ALC System
The ALC amplifier 010 (25C 1515) features high breakdown
voltage between collector, emitter and base. ALC voltage
1$ produced when the grid current flowing into the S2001A's
reaches about 30 A.
By setting the pull switch on the MIC/CAR VR to the
NORM position, ALC voltage is fed back to the proceeding
stage through the time constant circuit R72 and C59.
Control Section
- 011 is a switching transistor to cut off the transmitter 2nd
mixer Q1 when the heater switch is OFF.
Normally, Q11 is cut off by the negative bias voltage (with.
respect to emitter) applied from —C line through a shunt
resistor; the DC-DC converter stops oscillating when the
heaters are switched OFF, and. the base voltage of 011
becomes zero and a forward bias (with respect to emitter) is
applied, thereby the transistor turns ON. The bias resistor
of the transmitter 2nd mixer Q2 is connected to the collec-
tor of Q11 to provide negative bias to the Ist and 2nd |
gates, thus ОТ 1$ cut off.
During AC or DC operation, O1 and V1 are block biased
through either D8 or D9 when the heater switch is ON, thus
O1 and V1 are set in cut-off state.
Local Oscillator Circuit
A crystal oscillator circuit generates an oscillation frequency
for each band. It functions as a 2nd local oscillator during
transmission, and a Ist local oscillator during reception.
Crystals and oscillator coils are included in the OSC coil
unit (X44-1160-00). Oscillation is effected by Q6 (2SK-
19GR), while 07 (2SC460B) functions as a buffer amplifier.
Non-adjustment oscillator circuit 08 (2SC460B) is also
included for WWV reception, the output of which is applied
to O4. Local oscillator output for the DG-5 digital display
option appears through the buffer amplifier 09 (2SC460B).
The Drive (X44-1190-00),
MIX (X44-1180-00),
ANT (X44-1170-00), and
OSC Coil Units (x44-11 60-00),
function in conjunction with the RF unit. Coils, crystals
and rotary switches are neatly arranged on printed circuit
boards.
4. IF Unit (X48-1060-01)
This unit functions for both transmission and reception.
During transmission, the DSB signal from the generator
becomes a SSB signal while the unwanted side band and
carrier are suppressed by the SSB crystal filter XF1. The
SSB signal is IF amplified by Q1 (8SK35GR), which is com-
mon to transmission and. reception, and is fed to the trans-
mitter mixer O2 (3SK35Y). |
The local oscillator signal from the VFO unit is applied to
G2 of 02 while the cut-off frequency passes through the
7 MHz low pass filter (T10, 711, T12). The signal is mixed
with the SSB signal at G1. |
The converted 2nd IF signal is fed to the RF unit through
the band pass filter. During transmission, the receiver IF
amplifier ОЗ (3SK35GR), 04 (3SK35GR) and the receiver
VFO mixer 09 (35K41 L) are cut off by a nage tive voltage
at the RB terminal.
During reception, the Ist IF signal from the RF unit is fed
through the band pass filter to: the VFO mixer Q9, where
the signal is converted to the 2nd IF. This signal is fed
through the {FT to the NB, and its output is applied through
XF1 to the IF amplifier O1.
The signal is then amplified by the 2-stage IF amplifier (03,
Q4) and is fed to the ring detector of the generator. During
reception, the transmitter VFO mixer Q2 is cut off by a
negative voltage at the TBL terminal. ОБ (25K19GR) and
Об (2SK19GR) are AGC amplifiers. Об is used to select
SLOW, FAST and OFF AGC and control RF GAIN.
A diode switch is provided on the input and output of the
crystal filter so that the filter switches with the mode switcn
when the CW crystal filter YG-3395C (option) is installed,
During transmission, Q7 (2SK19GR) and 08 (25A495Y)
function as an ALC circuit,
They also function as an S
meter circuit during reception. —

CIRCUIT DESCRIPTION
5. NB (Noise Blanker Unit) (X54-1080-10)
_ Тне NB unit is divided into 2 circuits, a signal circuit and a
noise amplifier and switch circuit. — o
“In the signal circuit, the signal from the VFO mixer of the
IF unit passes through the 3-stage IFT band pass filter and
is amplified by 01 (8SK22GR). The signal is then applied |
to the NBO terminal of the IF unit through the balanced
blanking gate circuit.
in the noise amplifier, the noise signal amplified by Q2
(2SK19GR), ОЗ (2SC460B), 07 (25C460B) and 04 (2SC-
460B) is applied to the base of Q6 (25C733Y) through the
noise rectifier circuit consisting of D5 and Об (1N60). The
AGC time constant circuit O6 has no effect on pulse noise;
it functions for continuous, short-cycle signals such as SSB.
Accordingly, 03, 04 and 07 function in a state close to
maximum gain for pulse noise, and function in a state of
suppressed gain for continuous signals because of AGC
voltage.
With the NB switch ON, the emitter of 05 (25C733Y) is
grounded and when pulse noise is received, OS is turned ON.
The blanking gate diodes connected to O5 are reverse biased
by the time constant circuit C7 and RS, thus the signal line
is cut off to eliminate pulse noise. |
6. AF Unit (X49-0008-01)
The AF unit contains a complementary OTL (Output Trans-
formerless) audio frequency amplifier, semi-break-in circuit
for CW operation, side tone oscillator circuit for monitoring
and a detector circuit for calibration.
05 (2SC733Y) preamplifies the audio signal from the ring
detector. High frequency components are cut by C15 and
C18. |
The signal is further amplified by O1 and 02 (2SC733Y)
and then power amplified by 03 (25D90-0) and O4 (2SB-
473C, D, М).
The side tone circuit functions only when the MODE switch
is set to CW and the key connected to the KEY terminal is
ON. This circuit uses a phase-shift oscillator at about 750
Hz. During transmission, Q5 is cut off by + voltage at the
RL terminal.
When the optional DC-DC unit (DS-1A) is ‘operated from a:
DC power source, the side tone circuit does not function if
the H. SW is OFF, because the converter is also controlled
by the heater SW, hence, the bias voltage of Об (25C733Y)
and the control voltage for the switching diode ОЗ (181555)
are not generated. VR2 sets.the output level of side tone.
7. VEO Unit (X40-1070-01)
The VFO frequency range is 5.5 MHz ('0” on the sub dial)
to 4.9 MHz (''600” on the sub dial). |
01 (35K22Y) is a clapp oscillator, while O2 (25K19GR)
provides buffered output. The use of a 1-stage RF filter,
and Darlington output ОЗ and 04 (2SC460B), provides
stabilized operation against changes in load.
8. Marker Unit (X52-0005-01)
The 100 kHz crystal is energized by ОТ (2SC373).
Frequency is precisely adjusted by ceramic trimmer a
in the collector circuit.
Output of OT is shaped by diode D1 (1 N60) to synchronize
the multi-vibrator 02 and ОЗ (2SC373). The free running
_ frequency of the multi-vibrator is approximately 25 kHz and
is precisely synchronized to 25 kHz by Q1 output.
This signal is buffer amplified by 04 (25C373) to obtain
the required output. —
9. VOX Unit (X54-0001-00)
In SSB operation, voice signal from the MIC amplifier is fed
to the MV terminal (side tone output in the case of CW
operation). The signal is amplified by 03 (250373), recti-
fied by D6 (1N60) and becomes a DC signal proportional
to the input signal.
When DC voltage from D6 is applied to the base of O4
(25C373), 04 turns ON; as a result the voltage at the base
of 06 (25C373) is decreased.
When 04 is cut off during no-signal period, the base and
emitter voltages of 05 (2SA562Y) are equal, turning O5
OFF therefore, C10 is charged through D7, the voltage be-
ing set by the DELAY VR. This turns 04 and O5 ON,
discharging C10 through O5. This action, repeated, repre-
sents VOX hold time. |
Об and 07 (25C373) form a Schmidt circuit; when O4 is
OFF, 06 is ON and O7 is OFF. When 04 is ON, O6 is OFF
and 07 is ON, which, in turn, sets Q8 25A562Y) ON to
operate the standby relay. | |
The ANTI VOX signal from the output of the AF unit is
stepped up by 11 through the AV terminal and full-wave
rectified by D1-D4 to cut off Q1 (2SC373). |
When ОТ is OFF, СЪ is charged through R4 and, at the |
same time, 02 (25C373) is turned ON, thus the base of 04
is grounded; O4 turns OFF to stop the operation of VOX.

FUNCTIONAL DESCRIPTION
Speech Processor Theory
In DX operation, the early model TS-520 changed ALC
operation in 2 steps: to delay the rising ALC voltage and to
shorten its release time so that the average power during
SSB operation was increased. It offered reliable perform-
ance.
The TS- 520S has a unique circuit which suppresses the
spread of side bands and provides reliable function as a
processor. In this speech processor, the MIC amplifier cir-
cuit has an AGC type compression amplifier. Because the
time constant is relatively large, the amplifier has sufficient
compression effect with minimum distortion. It also
shortens the ALC time constant, which controls overall
transmitter gain. This increases the average output power
during SSB operation, without deteriorating signal quality.
The circuit is designed to provide approximately 6 dB com-
pression (at full scale ALC) at normal time constant, and
about 20 dB (at 10 mV of MIC input) through the low
frequency speech processor. =

Speech Processor Operation
Referring to Fig. 2, the MIC AMP input is amplified to 50
mV by the MIC amplifier. Amplifier output will be saturat-
ed if the input level exceeds this limit. As shown in Fig. 2,
the MIC amplifier output is saturated at approximately 70
mV when the processor is ON. The illustration also shows
the output at processor ON and OFF cross at 10 mV input.
This means these two outputs are equal at about 70 mV.
The MIC AMP input level is adjustable up to approximately
30 mV without excessive distortion, by means of VR3 in
the generator ‘unit (X52-1090-00).
At processor ON the operating curve shifts toward the left
from the OFF position. This shows the compression effect,
which is adjustable within the range shown by means of
VR2 in the generator unit. That is, MIC input can be ampli-
fied to approximately 70 mV by the compression amplifier.
If more than 10 mV input is used, the MIC amplifier output

is decreased at processor ON from the output !evel at proces-
sor OFF, if a microphone rated at less than 10 mV output
is used, the MIC amplifier output is increased at processor
ON. The relationship between MIC input and transmit
output is shown. in Fig. 3, that output is not increased at
excessive MIC input, nor increased at maximum compression.
Since semi-fixed resistors VR2 and VR3 are preadjusted,
the MIC gain control is used to adjust the input level within
the ALC zone. | o
In practical operation aft the transceiver, sound quality will
deteriorate if excessive input is applied, though this can be
eliminated by using an attenuator between the microphone
and the MIC input.
. Excessive MIC input can be checked by the setting of the
