The TS-2000/X basically consists of an all-mode-receiver
incorporating an IF/AF DSP for satellite communication with
an independent FM/AM sub-receiver for the VHF and UHF
bands.
■ Overview of the operation of the all-mode trans-
ceiver unit (main band side) with an IF/AF DSP
for satellite communication
The receiver unit has an independent front end for each
of the HF, 50MHz, 144MHz, 430MHz and 1.2GHz bands
(some products do not support the 1.2GHz band). The circuits following the 10.695MHz IF stage are common to all
the bands. (Thus, it cannot receive two SSB signals at the
same time.)
The IF frequency of the transmitter unit is shifted from
the IF frequency of the receiver unit by 100kHz to enable
satellite operation (full duplex operation). The final section is
independent of the HF, 50MHz, 144MHz, 430MHz and
1.2GHz bands. Consequently, you can select a combination
of bands permitting satellite communication from the HF,
50MHz, 144MHz, 430MHz and 1.2GHz bands.
The transmitter unit and receiver unit on the main band
side operate simultaneously during satellite transmission.
The receiver unit on the sub-band side does not work. (The
sub-band receiver is not used during satellite operation.)
Two 16-bit DSP ICs are used; one performs IF processing
(main band side) and the other carries out AF processing
(main and sub bands). Although the DSP IC is a 16-bit unit, it
carries out “double-precision operations” for critical parts of
IF processing to perform 32-bit equivalent processing. In
addition, the DSP IC uses a 100-MHz high-speed internal
clock. The conversion from an analog signal to a digital signal (A/D conversion) is performed with 24 bits at high precision.
The DSP circuit for IF operates in any mode other than
FM mode for both transmission and reception. FM modulation, detection and squelch processing are conventional analog processes. (The processing prior to modulation and after demodulation in FM is performed by the DSP.)
In the mode in which the IF DSP circuit operates, it carries out modulation and demodulation, digital IF filtering,
digital AGC, and CW waveform processing during transmission, as in the TS-870. All these functions are operated in all
the bands on the main band side, including satellite operation.
The AF unit is processed by the DSP in all modes. The
operating range of the DSP circuit depends on the mode,
but it performs beat cancellation, noise reduction, AF DSP
filtering, etc.
■ Overview of the operation of the independent
FM/AM sub-receiver unit (sub-band side) for the
VHF and UHF bands
The local oscillator system and IF/AF signal system of the
sub-receiver unit are independent of the main band side.
Therefore, the sub-band receiver can receive signals while
the main band receiver is sending a signal. (Except when
reception is impossible due to harmonics of the transmit frequency and when the main band and sub-band are on the
same frequency band.)
The sub-band receive signal is branched from the RF unit
on the main band side. It is, therefore, not necessary to
install a dedicated antenna for sub-band reception.
Transmission can be performed with the sub receive frequency by shifting the “PTT band” to the sub-band side. It
is made possible by internally using the transmission function on the main band side.
AF processing is also carried out by the DSP on the subband side and the noise reduction function works.
The sub-band reception function, including display, can
be turned off.
Frequency Configuration (Fig. 1)
This transceiver utilizes double conversion in FM mode
and triple conversion in non-FM modes during transmission.
It utilizes triple conversion in FM mode and quadruple
conversion in non-FM modes during reception. The fourth
12kHz IF signal is converted from analog to digital and connected to the DSP.
When the carrier point frequency of the signal input from
the antenna is f
when demodulating this signal is expressed by the following
equations:
HF MAINf
VHF MAIN f
UHF MAIN f
1.2G MAIN f
IN, the relationship between these signals
IN = fLO1 – fLO2 – fLO3 + fLO4 – 12kHz
IN = fLO1 – fLO2 – fLO3 + fLO4 – 12kHz
IN = fLO1 + fLO2 + fLO3 – fLO4 + 12kHz
IN = fLO1 x 2 + fLO2 + fLO3 – fLO4 + 12kHz
Reference Signal Generation Circuit
The 15.6MHz reference frequency fstd for PLL frequency
control is generated by the TCXO (X400). The signal passes
through a buffer amplifier (Q420) and is used as the reference signal for the second local oscillator (HFLO2) for HF
band reception and the first local oscillator (SLO1) subband
reception.
The reference signal is doubled by Q412, and the resulting 31.2MHz signal is used as the reference signal for DDSs
(IC406, IC407, IC408, IC601, IC602, IC603).
The 31.2MHz signal is supplied to the TX-RX2 unit (X57606 A/11) as LO2 for VHF and UHF bands.

One of three VCOs (Q459, Q460, Q464) is selected by
the signal (HF VCO1,HF VCO2,HF VCO3) from the serial-parallel IC (IC404).
The output from the VCOs (Q459, Q460, Q464) passes
through a buffer amplifier (Q462), is amplified by Q476, and
passes through a low-pass filter. The impedance is converted by an attenuator and the signal is output as HFLO1.
The cut-off frequency of the low-pass filter in the output
section is changed by turning Q474 ON/OFF with a VCO select signal (HF VCO1).

HF Receiver System and Main IF System
Three antenna terminals used for the HF and 50MHz
band reception are ANT1, ANT2 and HF RX ANT.
After the incoming signal from ANT1 and ANT2 passes
through the transmission/reception changeover relay in the
filter unit (X51-315), and is sent to the HFRX terminal of the
TX-RX unit (X57-605). There is an HF RX ANT terminal there,
and one of the antennas can be selected from the menu for
reception .
The HF RX ANT terminal is used to connect a dedicated
HF-band low-band receiving antenna, such as a Beverage
antenna, and operates at frequencies up to 30MHz. (If an
antenna, such as a solid wire antenna, is connected to this
terminal, unwanted radio signals in the shack may be picked
up. It is recommended that a 50 (coaxial cable be used for
routing in the shack.)
The signal passes through an RF ATT, an image filter and
a limiter for surge absorption and enters the RF BPF for both
transmission and reception. The division of the RF BPF is in
the range shown in the block diagram. For 6.9~7.5MHz,
13.9~14.5MHz and 49~54MHz, a dedicated BPF (adjustable
type) is used and particularly effective for eliminating unwanted signals in the low band. Other BPFs (non-adjustable
type) are designed as circuits with independent armature
bands, except that the 24MHz and 28MHz bands are
shared. Signals pass through these BPFs at the time of
transmission, so they are useful for producing radio signals
with little radiation.
Although the conventional RF ATT had an attenuation
level of 20dB, the attenuation level of the current RF ATT is
12dB. It can, however, be changed to approximately 20dB
by removing the jumper (CN2) near the ATT within the unit.
The pre-amplifier (Q12, Q705) have been changed to a
power MOS FET from the combination of the conventional
cascade amplifier and MOS FET amplifier. This element is a
FET that is used in a younger stage for transmission and has
excellent large input characteristics. The actual circuit contains two amplifiers using this FET. Large input characteristics with a low gain are given priority on the low band (Q12)
with respect to 21.5MHz, and sensitivity is given priority on
the high band (Q705). circuit on the low band side bordering
21.5 MHz favoring a gain with moderately large input characteristics and that on the hybrid side (Q705) favoring .
When the pre-amplifier is off, the signal from the RF BPF
enters the receiving first mixer (Q7~Q10) in the next stage
as it is.
The receiving first mixer circuit uses a double balance
type mixer with four joint type FETs. The signal is converted
to the first IF frequency by the first local oscillator signal.
The TS-2000S has adopted a method that changes the first
IF frequency according to the receive frequency. For this
reason, it has two sets of roofing filters (MCF) that determine the selectivity of the first IF. Table 1 shows the relationship between the receive frequency and the first IF frequency. The central frequencies for the reception and
transmission of the first IF frequency are different from each
other by 100kHz because the transmission and reception is
performed simultaneously during satellite communication.

CIRCUIT DESCRIPTION
The signal is then amplified by the first IF amplifier (Q18)
and is converted to the second IF frequency of 10.695MHz
in the second receive mixers (Q19, 20). The tuning frequency of each stage, the second local oscillator frequency
and others are changed according to the receive frequency
to respond to the changeover of the previously stated first IF
frequency.
A circuit for changing over the IF signal from the units of
the VHF, UHF and 1.2GHz bands and IF signal from the HF
band is provided on the output side of the second receive
mixer. That is, the circuits following this stage are commonly used circuits, regardless of the receive frequency on
the main side.
In addition, there is a semi-fixed volume (VR4) on the output side of the first receive mixer. The volume is used to
eliminate the gain differential generated due to the
changeover of the first IF frequency.
The signal for the noise blanker is extracted from this
point by passing through Q22. The noise blanker circuit is
based on the same principle of operation as the conventional one, but can change the threshold level by changing
the emitter potential of the noise detection stage (Q29).
The 10.695MHz signal is amplified by Q26 which also
serves as a noise blanker gate circuit and passes through a
10.695MHz IF filter. It has three bandwidths, 2.7kHz, 6kHz
and through, and when it is combined with the 455kHz filter
group, the same continuous band change function (analog IF
throughput: operation in modes other than FM) as in con-
ventional analog devices is implemented. The band in this
analog stage does not affect the operation of the digital IF
filter in the IF DSP and is automatically set to the optimum
band for removing unwanted signals outside the band.
Then, the signal is converted to the third IF frequency of
455kHz in the third receive mixer (Q700, 701). The 455kHz
filter has three bandwidths: 2.7kHz, 9kHz and 15kHz. In FM
mode (main band side) the 15kHz filter is selected for WIDE
and the 9kHz filter is selected for NARROW, and signals
passing through the filter are sent to the FM IC (ICI), amplified and detected. IC1 processes squelch, S meter, etc.
As a characteristic operation in this stage, a tuning error
detection voltage for the ALT function operating in the
1.2GHz band FM mode is generated. It utilizes the DC voltage that is overlapped with the ICI detection output.
In a mode other than FM, the receive signal is amplified
by the next third IF amplifier (Q38) and operational amplifier
(IC18) and converted to the final 12kHz IF frequency by the
fourth receive mixer (IC3). The converted IF signal in FM
(audio signal) and non-FM mode (IF signal) is selected by the
multiplexer (IC7) and the signal is sent to the DSP of the
control unit for processing. The signals processed in the
control unit become audio signals in all modes and return to
the TX-RX1 unit (X57-605). These audio signals are power
amplified to the level that drives the speaker with the AM
amplifier (IC9).
A speaker separation function is available as an accessory circuit. The bands can be changed as shown in Table
14.

Main VHF/UHF Band Front-End and
Sub Receiver System
The VHF and UHF band receiver circuit is configured with
two systems, a main band (FM/ AM/ SSB/ CW/ FSK) and a
sub-band (FM/AM), each of which has a VHF and a UHF
band path.
In the main band, the first IF is 41.895MHz and the second IF is 10.695MHz and the signal lower hetero to the second IF is sent to the TX-RX1 unit (X57-605) and linked to the
second IF, which is shared by the other bands. The subband is a double conversion where the first IF is 58.525MHz
and the second IF is 455kHz. It is configured so that detected AF signals are sent to the control unit (X53-391).
■ VHF/ UHF band front end
The circuit operation of the sub-receiver unit differs depending on whether it is for K destination or others. The
circuit operation for each of the destinations is described
below.
• K destination
The incoming signal from the VHF band antenna terminal
passes through the TX/RX changeover relay (K2) in the filter
unit (X51-315) and goes to the TX-RX2 unit (X57-606). Then,
it passes through the 12dB ATT circuit and is divided to the
136~155MHz path and the 118~136MHz, 155~174MHz
and 220~300MHz path by the L distribution circuit. The
136~155MHz signal passes through a 2-pole BPF (bandpass filter) and enters the pre-amplifier (Q15). The amplified receive signal is again distributed to the paths for the
main and sub receiver units by the L distribution circuit.
The signal distributed to the main receiver unit passes
through the 2-pole variable tuning BPF, is amplified by the
second amplifier (Q24) and goes to the mixer (IC4) for the
main band common to the VHF and UHF bands through the
variable tuning BPF. The 2-pole x 2-stage BPF for the main
band VHF controls the tuning frequency by output from the
D/A of the TX-RX1 unit (X57-605).

CIRCUIT DESCRIPTION
The 118~174MHz signal distributed to the sub-receiver
unit passes through a variable tuning filter and is amplified
by the second amplifier (Q24). Then, it passes through the
2-pole variable tuning BPF, and the 220~300 MHz signal is
amplified by Q23 and is then input into the mixer (IC5) for
the sub-band common to the VHF and UHF bands. The 1pole and 2-pole BPFs for the sub-band VHF also controls the
tuning frequency by the output from the D/A of the TX-RX1
unit (X57-605).
The incoming signal from the UHF band antenna terminal
enters the UHF section of the final unit (X45-360), passes
through the HPF and LPF and goes to the TX-RX2 unit (X57-
605). Then, it passes through the 12dB ATT circuit and goes
to the pre-amplifier (Q14). The amplified receive signal is
distributed to the paths of the main and sub-receiver sections by the L distribution circuit.
The signal distributed to the main receiver section
passes through the 3-pole variable tuning BPF and is amplified by the second amplifier (Q21). Then, it passes through
the 3-pole variable tuning BPF and is input into the mixer
(IC4) for the main band.
This 3-pole x 2 stage BPF for the UHF also controls the
tuning frequency by the output from the D/A of the TX-RX1
unit (X57-605).
Filter
X51-315
VHF
The 438~450MHz signal distributed to the sub-receiver
section passes through the SAW filter (L29), is amplified by
the second amplifier (Q25), and passes through another
SAW filter (L50). The 300~438MHz and 450~512MHz signals are amplified by Q19 and goes to the mixer (IC5) for the
sub-band.
• E, E2 destinations
Then, the signal passes through the 12dB ATT circuit and
the 2-pole BPF (band-pass filter) and enters the pre-amplifier
(Q15). The amplified receive signal is distributed to the
paths of the main and sub receiver sections by the L distribution circuit.
The signal distributed to the sub-receiver section passes
through a variable tuning filter and is amplified by the second amplifier (Q22). Then, it passes through the 2-pole tuning BPF, and goes to the mixer (IC5) for the sub-band common to the VHF and UHF bands. The 1-pole + 2-pole BPFs
for the sub-band VHF also control the tuning frequency by
the output from the D/A of the TX-RX1 unit (X57-605).
The signal distributed to the sub-receiver section passes
through the SAW filter (L29), is amplified in the second amplifier (Q25), passes through another SAW filter (L50) and
goes to the mixer (IC5) for the sub-band.

■ Main receiver IF section
The signal input to IC4 is mixed with the signal produced
by amplifying the first local oscillator RXLO1 from the PLL
section by Q30 and lower hetero to the first IF of
41.895MHz. Then, it passes through the MCF (XF1) and
AGC amplifier (Q38) and goes to the second mixer (Q42 and
43). The signal input to the second mixer is mixed with the
signal produced by amplifying the second local oscillator
21.2MHz from the PLL section by Q44 and lower hetero to
the second IF of 19.695MHz. The signal then passes
through a temperature compensating resistor and the IF
amplifier (Q61) and is sent to the TX-RX1 unit (X57-605).
■ Sub receiver IF section
The signal input to IC5 is lower hetero to the first IF of
58.525MHz. In the VHF band, the local oscillator SLO1 from
the PLL section is divided into two by the divider (IC6) and
passes through amplifier (Q23). In the UHF band, the IF signal passes through amplifier (Q33) and is input to IC5. The
IF signal passes through the MCF (XF2), passes through the
post amplifier (AGC amplifier in the AM mode) Q37 and
goes to the FM IC (IC7). The local oscillator is supplied to
IC7 by the 58.07MHz crystal oscillator (X1) and is lower
hetero to the second IF of 455kHz by a mixer in the IC.
The circuit operation when the signal passes through a
ceramic filter after lower hetero is different for K destination
and E destination. The circuit operation for each of the destinations is explained below.
• K destination
In FM mode, the signal passes through a ceramic filter
(CF1), is quadrature-detected, and the resulting signal is output.
• E, E2 destinations
The signal passes through a ceramic filter (CF1) in FM
WIDE mode and it passes through a ceramic filter (CF2) in
FM NARROW mode. The signal is then quadrature-detected and the resulting signal is output.
In AM mode, a 455kHz signal passes through the AGC
amplifier (Q51) and amplifier (Q48 and Q45) and is detected
by D58. The detection signal retrieved for the AGC is rectified, passes through the DC amplifier (Q39) for AGC control
and goes to the Q37 gate terminal (G2).
The FM/AM detection signal is switched by the multiplexer (IC8). Then, it is amplified by the operational amplifier
(IC9) and output to the control unit (X53-391).
■ Squelch voltage and S-meter voltage of the sub
receiver section
The S meter voltage is introduced to the A/D through a
LPF for RSSI output of the FM IC (IC7).
The squelch voltage is supplied to the A/D by passing the
detection output of the FM IC through a filter amplifier in the
FM IC, amplifying it with the noise amplifier (Q63), and rectifying it with D83.

Transmit System IF Section
■ Transmission IF
The details of the processing by the DSP depend on the
mode.
• Modes other than FM
Transmission bandwidth change, speech processor and
microphone gain control are performed in the AF stage. A
12kHz IF signal is produced after PSN modulation and output modulation control.
• FM mode
The baseband processing in the AF stage is carried out by
the DSP and a VCXO (voltage controlled X’tal Oscillator) is
used as a modulator.
The transmit signal output from the control unit (X53-391)
is switched by an analog SW (IC8) and is input to the balanced mixer (IC6). The 12kHz IF signal and local oscillator
signal enters the IC6 and become a 10.595MHz signal. The
local oscillator signal is generated by the DDS (IC602).
The 10.595MHz IF component is amplified by the IF amplifier (Q54) and passes through the 6kHz bandwidth crystal
filter, then becomes a 10.595MHz IF signal by eliminating
local oscillator signals. The diode switch (D90) changes between FM modulator output and non-FM 10.595MHz IF signals.
The temperature compensation of the transmitter circuit
is done by the thermistor near the IF amplifier (Q54) and the
thermistor on the input side of the IF amplifier (Q711). They
reduce the gain at low temperatures and raise it at high temperatures.

signal
The output signal from the IF amplifier (Q711) passes
through D84, Q40, D82, D48, D80 and D81 and becomes
the IF transmit signal for each band. D84 is a voltage controlled attenuator circuit. This circuit changes the attenuation level according to the control voltage (TGC), in the same
way as the TGC (TX gain control) used in the TS-870 and TS570 and is set to the adjusted attenuation level for each
band. Q49 is an IF amplifier circuit with an ALC circuit. The
gain is controlled by the voltage generated by the ALC circuit.
D82 is a voltage controlled attenuator circuit as D84. The
attenuation level is minimum at full power and as the power
decreases, the control voltage rises and the attenuation
level increases. When the power is reduced, the gain will
become relatively excessive if the IF gain is not lowered. It
is set to an attenuation level adjusted by the PGC (Power
Gain Control) accordance to the power of each band.
Q48 is an IF output buffer. It changes to the transmitter
section of each band with a diode switch (D80, D81) to supply a 10.595MHz IF signal.
During transmission in the 144MHz and 420MHz bands,
the signal is output to the TX-RX2 unit (X57-605), and during
transmission in the 1.2GHz band, it is output to the TX-RX3
unit (X57-605).
In the 1.8~54MHz band, the frequency is converted to
the final target transmit frequency in the TX-RX1 unit (X57-
605).
The local oscillator frequency changes according to the
band in second transmit mixer of Q46 and 47 to generate
different IF frequencies. (TX third IF: 68.985MHz or 75.825
MHz)
D703 and D715 are used to change the tuning frequency
of the local oscillator signal and D79, D78, D77 and D76 are
used change the frequency of the IF filter (L102).
The variable tuning filter containing these variable capacitance diodes performs the coarse adjustment of the coil
(L100, L99, L98, L96, L102) in the band (18.085MHz) where
the IF is 75.825MHz. Then, it changes the tuning frequency
control voltage from the D/A in the band (14.100MHz)
where the IF is 68.985MHz and tunes it to the necessary
frequency by readjusting the coil.

CIRCUIT DESCRIPTION
The third IF signal is input to the third transmit mixer
(Q44, 45).
A GaAs FET is used to obtain the satisfactory intermodulation characteristics. VR3 adjusts the second gate
voltage to maximize the gain. VR2 adjusts the balance of
the source current of two FETs and prevents the generation
of spurious components by minimizing IF output leakage. It
also adjusts the leakage of the IF signal (68.985MHz) to the
minimum during 50MHz band transmission.
The signal with the target frequency passes through the
BPF shared by the receiver section to eliminate spurious
components. The transmitter circuit is separated from the
receiver circuit to implement satellite communication, but
only this BPF is shared to prevent generation of spurious
components.
Finally, the signal is amplified to a sufficient level (approximately 0dBm) by the broadband amplifier and supplied
to the final section. Q43 is a power MOS FET and provides
an output of approximately 20dBm when the ALC is inactive.

■ ALC
The progressive and reflected wave signals detected by
the final section in each band enters the TX-RX1 unit (X57-
605) and is synthesized by a diode. It is synthesized simply
because no signal is transmitted in multiple bands at the
same time.
When the progressive signal voltage is input, it is divided
by a resistor, and enters the differential amplifier composed
of Q73 and Q74. When the voltage increases, the emitter
voltage rises, the base current of Q74 decreases, and the
collector voltage of Q74 also rises. When the voltage exceeds the base emitter voltage plus the emitter voltage (approximately 2.4V) of Q76, the base current of Q76 begins to
flow and the voltage of the collector to which the ALC time
constant CR is connected decreases. This collector voltage
is buffered by Q78, the voltage is shifted by D108, and
matched with the keying control voltage by Q79 and D111
to produce the ALC voltage. When the ALC voltage (2.7V
when inactive) decreases, the second gate voltage of the IF
amplifier (Q49) decreases and the gain lowers.
During AM transmission, Q75 turns on approximately
20ms after transmission, and the ALC voltage is controlled
by the average power. The voltage output from the DAC
(IC14) is applied to the base voltage of Q74, which is the
reference voltage of the ALC. This DAC (IC14) is controlled
by the adjustment value (POC) from the main microcomputer. In addition, the input voltage of the DAC fluctuates
according to the power supply voltage and the output drops
when the voltage is reduced.
■ SWR protection
The reflected wave detection signal is divided by the
DAC (IC14) and input to the base of Q77. When this voltage
increase, the collector current of Q77 increases and output
power is limited.
■ Meter voltage
The progressive wave voltage is calculated as the power
meter voltage, the reflected wave voltage is calculated as
the progressive wave voltage and its value is input as the
SWR meter voltage, and the ALC voltage is input as the ALC
meter voltage. These voltages are input into the A/D converter of the main microcomputer.
■ Packet signal
The control unit contains a TNC and a changeover switch
circuit that enables data signals to input from the ACC2 connector. (See the block diagram)
The 1200bps signal is processed by the DSP in the same
way as for audio signals, but the 9600bps signal is input directly to the FM modulator without passing through the
DSP.

VHF/UHF Band Transmitter Circuit (RF~IF)
The TIF (10.595MHz) signal input from the TX-RX1 unit
(X57-605) first enters the mixers (Q46 and 47). The
31.2MHz signal from the PLL passes through the RF amplifier (Q50), enters the mixer as a local oscillator to output the
41.795MHz IF through both the signals. It passes through
the 41.795MHz MCF (XF3) and enters the wideband diode
mixer (D54) in the next stage, and upper hetero to a VHF/
UHF band output signal. The local oscillator TXLO1 of the
mixer is on a common line for both VHF and UHF band local
oscillators, and the local oscillator signal is amplified by the
VHF and UHF band broadband amplifier (Q34) and supplied
to the mixer.
The signal converted to the VHF/UHF band is divided into
a VHF band path and a UHF band path after it is output from
the mixer.

The VHF band signal passes through a filter and a trap
and is amplified in the 2-stage RF amplifiers (Q20, Q18), and
the resulting signal goes to the wideband amplifier (IC3)
common to the VHF and UHF bands.
The UHF band signal is amplified by the RF amplifier
(Q17), passes through a 3-pole variable tuning BPF and is
amplified by the amplifier (Q26). Then, it passes through a
2-pole variable tuning BPF and enters IC3. The total 5-pole
variable tuning BPF controls the tuning frequency according
to the control signal output from the D/A converter of the
TX-RX1 unit (X57-605).
The signal amplified by IC3 is again divided into VHF band
and UHF band paths by a diode switch and output to the
final unit (VHF band: X45-360 A/2, UHF band: X45-360 B/2).

CIRCUIT DESCRIPTION
Transmitter Final Amplifier
The final unit (X45-360 A/2) is composed of an HF and
VHF band final amplifier, an antenna turner matching circuit,
and a power supply circuit.
The LPF section and antenna tuner detection circuit are
located in the filter unit (X51-315).
The 1.8~144MHz band is amplified by the final unit, but it
operates in the broadband up to the drive amplifier. The
final unit amplifies signals using independent amplifiers in
the 8~50MHz and 144MHz bands. The amplifiers are
switched with a diode switch (D1).
■ Q1 : First stage amplifier
This amplifier uses a FET. It has frequency characteristics so that the gain increases in the 144MHz band.
■ Q2 : Pre-drive amplifier
This amplifier uses a bi-polar transistor. It has unique frequency characteristics.
■ Q3 and 4 : Drive amplifier
This is a push-pull type amplifier. It amplifies a signal
with a broadband up to the 144MHz band, then the signal is
branched to the HF and 144MHz bands through a relay.
■ Q6 and 7 : HF final amplifier
This amplifier uses a bipolar transistor with push-pull. It
amplifies a signal up to the 54MHz band, using an output
transformer with a coaxial cable. It outputs the signal to the
LPF section through an effective and light matching circuit in
the 50MHz band.
■ Q101 and 102: 144MHz final amplifier
A 144MHz band signal passes through the HPF and en-
ters the branch circuit with two amplifiers.
It functions as a parallel amplifier that branches the signal
with the same phase, amplifies it with the Q101 and 102
amplifiers and re-synthesizes it. As a result a 100W output
is produced.
Since the output matching section is an LPF type, it attenuates harmonics as well. After the output has been synthesized, it detects the power of the progressive wave and
reflected wave with a directional coupler according to the
strip line, and outputs it to the LPF section.
■ LPF section
In the 1.8~50MHz band, the signal passes through the
LPF as shown in Table 3.
It has an independent LPF circuit and an antenna
changeover circuit for the 144MHz band.
The signal output from the LPF passes through the detection circuits, the transmission/reception changeover relay (K1), the antenna tuner changeover relay (K3) and the
antenna changeover relay (K4) and is output to ANT1 or
ANT2.
Progressive wave and reflected wave output circuits
The signal is detected by L7, D3 and D4. A voltage output corresponding to the progressive wave and reflected
wave is produced by synthesizing the magnetically combined component by L7 with the corrected electrostatically
combined component by TC1 and C9 and detecting the resulting signal.
It is adjusted by TC1 so that the reflected wave voltage
under a 50Ω load is minimized. VR1 adjusts the frequency
characteristics in the 50MHz band.
These outputs are synthesized with detected output of
the 144MHz band and are fed to the TX-RX1 unit (X57-605).
■ Antenna turner detection circuit
The passing current is converted to voltage by L9, and
the voltage is stepped down and detected by L10. One of
these components is buffered by Q1 and Q2 and rectified by
Q3 and Q4, are input to the phase comparator (IC2) . The IC
determines the IC2 Q output “H” or “L” according to the
phase difference with a D-flip-flop. The other component is
detected by diodes (D10 and D11) and the amplitude difference is compared with the comparator (IC1).
The capacitor capacitance on the input side is changed
according to the phase difference detection output, and the
capacitor capacitance on the output side is changed according to the amplitude difference detection output.
■ UHF final unit (X45-360 B/2)
The 430MHz band transmit signal output from the TXRX2 unit (X57-606) is amplified to 50W by four amplifiers
(Q901, 902, 903 and 905). The final unit consists of single
amplifiers Q901, 902, 903 and 905. The input and output of
the final stage is composed of micro-strip lines. The progressive wave and reflected wave detection circuit is also
made of micro-strip lines and used for power control and
reflected wave protection.

1.2GHz Unit Transmitter Section
The 10.595MHz transmit signal from 12TIF is amplified in
the sending IF amplifier (Q304). This signal is input into the
sending mixer (Q1 and Q2).
The 135.395MHz signal converted in Q1 and 2 passes
through the MCF (XF2) and IF amplifier (Q3), is input into the
diode mixer (D1) and converted to 1240~1300MHz. This
signal is amplified to approximately 0dB in the sending RF
amplifier (IC1 and Q5), then input to IC2.
It is amplified to approximately 1W in the drive power
module (IC2) and to approximately 10W in the final power
module (IC3), then sent to the antenna terminal (12ANT).

CIRCUIT DESCRIPTION
Digital Control Circuit
■ Outline
The TS-2000/X control circuit has a multi-chip configuration centered around a main microcomputer (IC8), and contains a latch circuit for input/ output, a TNC and a DSP. Refer
to the digital control block diagram.
■ Main microcomputer peripherals
Four serial communication devices utilizing a UART function (panel microcomputer, TNC, mobile head and PC serial
port) are connected to the main microcomputer. An
EEPROM (IC7) for backup and a DTMF decoder (IC12) for
DTMF signal detection are also connected to the microcomputer.
The input/output circuit and DSP are connected through
an address bus and a data bus. The bus to the DSP is connected through 5V ↔ 3V voltage conversion ICs (IC9, IC10,
and IC11)
The microcomputer operates with an internal core voltage of 3.3V, an external I/O voltage of 5V and an internal
frequency of 22.1184MHz (11.0592MHz x 2).

computer
2 Chip TNC
(by TASCO)
Mobile
head
■ TNC
The TNC is the same as the one used in the TH-D7. The
TNC uses a lithium battery to back up various settings.
When a 9600bps communication speed is used, the TNC
analog signal is connected directly to the transmitter/receiver circuit without passing through the DSP.
■ Input/output latch circuit
A latch IC is used in stead of several input/output ports.
Since the latch IC has a latch function only, the latch circuit
contains an input latch logic circuit (IC13, IC14, IC15) and an
output latch logic circuit (IC16, IC17, IC18) to generate the
signals required for the latch IC using the main
microcomputer’s address bus information. This configuration is also used for the latch IC of the DSP section.
■ Other peripheral circuits
The main microcomputer is connected with other peripheral circuits, such as a reset circuit that generates a reset
signal, a reduced voltage detection circuit that detects reduced voltage and generates a reduced voltage signal, and
an over-voltage detection circuit that detects over-voltage
and generates an over-voltage signal.

CIRCUIT DESCRIPTION

■ Firmware
The main microcomputer firmware includes adjustment
firmware and user firmware. When repairs or adjustments
are made in service, the user firmware must be rewritten to
make adjustment firmware. It must be restored to the original user firmware after repairs or adjustments. The adjustment firmware provides a warning display and a warning
sound when the power goes on.
DSP Circuit
■ Outline
The TS-2000/X DSP circuit is composed of two DSPs
(IC515 and IC516) and CODEC ICs (IC518, IC522 and
IC523), an input latch circuit, flash ROM (IC504 and IC508).
It is connected with the main microcomputer (IC8) by an
address bus and a data bus through the voltage conversion
ICs (IC9, ID10 and IC11). The SSB, CW, AM and FSK detection, modulation and AGC operation are done by the DSP,
and digital processing (digital filtering, noise reduction, etc.)
is performed in all modes.
■ DSP
The DSP operates with an internal core voltage of 1.8V,
an external I/O voltage of 3.3V and an internal frequency of
99.5328MHz (11.0592MHz x 9).
The two DSPs perform the respective IF processing and
AF processing. The IF processing is done by DSP2 (IC515)
and a 24 bit CODEC IC (IC518) is connected to it. DSP2
performs detection, modulation, AGC processing and IF
digital filtering. It is designed so it does not exceed the processing time, even if the main band transmission and reception and sub-band reception are done simultaneously. An
output latch circuit is connected to DSP2 to convert the analog AGC voltage signal from digital to analog before output.
The conversion is done by the ladder resistance method.
The AF processing is done by DSP1 (IC516) and a 16 bit
CODEC IC (IC522, IC523) is connected to it. DSP1 performs
the speech processing (signaling generation, detection,
noise reduction, speech filtering, and various volume processing). The input latch circuit is connected to DSP1 and
various signals from the main microcomputer and the microphone selection signal are input into it.
■ Flash ROM
The respective programs and data are stored in the Flash
ROM (IC508 and IC504) connected to DSP1 and DSP2.
■ CODEC IC
A 24 bit CODEC IC (IC518) is used as the IF signal system. DSP2 carries out 32 bit digital processing for detection
and modulation. The operation of this IC is controlled by the
main microcomputer.
Two 16 bit CODEC ICs (IC522 and IC523) are used as the
AF signal system. These IC outputs directly enter the AF
amplifier, are amplified and then output from the speaker.
The IC input consists of the MIC input and the optional
speech synthesis unit (VS-3).
The various timing signals required by both CODEC ICs
are generated and supplied by a 12.288MHz quartz crystal
and a peripheral circuit.
■ Communication between DSPs
DSP1 and DSP2 are connected via serial communication
and perform such interchanges as audio signals for transmission processed in DSP1, received speech signals detected in DSP2 and information from the DSP1 input latch
circuit. If this interchange does not go well when the power
starts up, a “DSP COMM” error will be displayed on the
LCD and the fact that the DSPS is not operating will be notified to the main microcomputer. Likewise, when the content of the flash ROM is abnormal, a “DSP COMM” error is
displayed.

20VDD–Power
A19~A0O/ZParallel address bus A19 (MSB) to A0 (LSB). The low-order 16 bits (A0 to A15) of the address pin are multiplexed to
address to external memory (data, program) or I/O. The high-order 4 bits (A16 to A19) are used to address to external
program space. These pins are high impedance when in hold mode or when OFF is low.
D15~D0I/O/ZParallel data bus D15 (MSB) to D0 (LSB). D15 to D0 are multiplexed to transfer data between the core CPU and
external data/program memory or I/O device. The data bus becomes high impedance when data is not output or
RS or HOLD is low. It also becomes high impedance when OFF is low.
The data bus has a bus holder to reduce power consumption of unused pins. When there is a bus holder, external
bias resistors for unused pins are not necessary. When '5402 does not drive the data bus, the bus holder retains the
preceding logic level pin. The '5402 data bus holder is disabled on reset, and enabled/disabled through the BH bit of
the bank switching control register (BSCR).
Initialization, interrupt and reset operation
IACKO/ZInterrupt signal. Interrupt reception and interrupt vector specified by A15 to A0 are fetched by the program counter.
It becomes high impedance when OFF is low.
INT0~IExternal user interrupt input. INT0 to INT3 have priorities and can be masked by interrupt mask resister (IMR) and
INT3interrupt mode bit. Polling and reset can be performed by the interrupt flag register (IFR).
NMIIInterrupt signal that cannot be masked. This external interrupt cannot be masked by INTM or IMR.
When NMI is low, the vector is trapped.
RSIReset. RS stops DSP operation and initializes the CPU and peripheral. When RS goes high, execution starts from
0FF80h address of the program memory. RS affects various registers and status bits.
MP/MCIMicroprocessor/microcomputer mode selection. If it is low on reset, the microcomputer mode is selected, and the
internal program ROM is mapped to the high-order 4K words of the program memory space. If it is high on reset, the
microprocessor mode is selected and the onchip ROM is erased from the program space. This pin is sampled only on
reset, and when the MP/MC bit of the processor mode status (PMST) register is reset, the selected mode is made invalid.
Multi-processing signal
BIOIBranch control. When BIO is active, a conditional branch can be executed. When it is low, the processor executes a
conditional branch. The XC instruction samples BIO condition in the pipeline decode phase. Other instructions sample
BIO in the read phase.
XFO/ZExternal flag output (latch signal that can be changed by software). It is set to high by SSBX XF instruction, and set to
low by loading an RSBX XF instruction or ST1. This signal is used as a communication or general output signal when
several DSPs are used. It becomes high impedance when OFF signal is at low level, and is set to high level on reset.
Memory control signal
DSO/ZData, program, or I/O space select signal. It is always at high level, except when it is driven at low level to access a
PSspecific external memory space. It is active while the address is effective. In hold mode, it becomes high impedance
ISwhen the OFF signal is at low level.
MSTRBO/ZMemory strobe signal. It is always at high level, except when accessing data or program memory through an external
bus. In hold mode, it becomes high impedance when the OFF signal is at low level.
READYIData ready signal. It indicates that an external device has finished preparing accessing a bus.
If it is not ready (READY is at low level), it waits one cycle and checks the READY signal again. At least two software
wait states must be programmed for the processor to detect a READY signal. The READY signal is not sampled until
software wait states are complete.
R/WO/ZRead/write signal. It indicates the direction of data transfer with an external device. It is normally at high level (read
mode) except when it goes low to execute a write operation. In hold mode, it becomes high impedance when the
OFF signal is at low level.

IOSTRBO/ZI/O strobe signal. It is always at high level (read mode) except when accessing an I/O device through an external bus.
In hold mode, it becomes high impedance when the OFF signal is at low level.
HOLDIHold input signal. Address, data, or control signal control input signal. When this signal is accepted, the address,
data, or control signal becomes high impedance.
HOLDAO/ZHold response signal. It notifies the external circuits that the processor is in hold state and the address, data and
control signals are high impedance so that they can be used by the external circuits. It becomes high impedance
when the OFF signal is at low level.
MSCO/ZMicrostate completion signal. MSC indicates that all software wait states are complete. When several software wait
states are enabled, MSC becomes active at the beginning of the first software wait state and becomes inactive high
at the beginning of the last software wait state. When READY input is connected, MSC inserts an external wait state
forcibly after completion of the last internal wait state.
IAQO/ZInstruction capture signal. It becomes active low when an instruction address is on the address bus. It becomes high
impedance when the OFF signal is at low level.
Oscillator/timer signal
CLKOUTO/Z
CLKMD1IClock mode select signal. These input signals are used to select a mode that is initialized after the clock generator is

10,19 AGNDAnalog ground. The ground return for the
analog circuitry (DAC and comparator).
11,18 AVDDPositive supply voltage for analog circuitry
(DAC and comparator, pin 18) and bandgap
voltage reference (pin 11).
12RSETThe DAC’s external RSET connection–
nominally a 3.92kΩ resistor to ground for
10mA out. This sets the DAC full-scale
output current available from IOUT and
IOUTB. RSET = 39.93/IOUT.
13VOUTNVoltage output negative. The comparator’s
“complementary” CMOS logic level output.
14VOUTPVoltage output positive. The comparator’s
“true” CMOS logic level output.
15VINNVoltage input negative. The comparator’s
inverting input.
16VINPVoltage input positive. The comparator’s
noninverting input.
17DACBPDAC bypass connection. This is he DAC
voltage reference bypass connection
normally NC (no connect) for optimum
SFDR performance.
20IOUTBThe “complementary” DAC output with
same characteristics as IOUT except that
IOUTB = (full-scale output – IOUT). Output
load should equal that of IOUT for best
SFDR performance.
21IOUTThe “true” output of the balanced DAC.
Current is “sourcing” and requires current
to voltage conversion, usually a resistor or
transformer referenced to GND.
IOUT = (full-scale output – IOUTB).
22RESETMaster reset pin, active high, clears DDS
accumulator and phase offset register to
achieve 0Hz and 0° output phase.
Sets programming to parallel mode and
disengages the 6 x REFCLK multiplier.
Reset does mot clear the 40-bit input
register. On power up, asserting RESET
should be the first priority before programming commences.
23DVDD

■ Outline
1. The TS-2000/X can be adjusted manually (by turning a
coil, trimmer, etc.) or by setting the service adjustment
mode (adjustment with panel keys). In the service adjustment mode (simply referred to as the adjustment
mode below), adjustments items are shown in menu
No.00 to 126 and all data are saved in the EEPROM (X53391: IC7).
2. To enter adjustment mode, the user firmware in the main
unit must be rewritten with adjustment firmware. (The
user firmware is factory-set.)

■ Procedure for writing adjustment firmware (for
both user and adjustment firmware)
1. Remove the lower case and set the slide switch (S1) of
the TX-RX 1 unit (X57-605A) to ON (move the switch toward the front).
2. Connect the RS-232C port of the personal computer with
the COM port of the main unit with a D-SUB (9-pin)
straight cable (female-female).
3. Connect the external power supply (13.8V) to the main
unit and turn the power supply ON. The main unit does
not turn on any indicators, but it is ready to rewrite firmware. Do not operate the power switch on the main unit.
4. Write firmware using writing software. (See the help of
the software for information on how to write it.)
5. After writing the firmware, turn the external power supply OFF and remove the RS-232C cable.
6. Set the slide switch (S1) of the TX-RX 1 unit (X57-605A)
to OFF (move the switch toward the rear).
7. Turn the external power supply ON.
8. Turn the main unit ON and confirm that the indicator
lights. Then, perform all reset (hold down [A=B] key and
press the [POWER] key) and confirm that the initial state
is displayed.
9. After adjustment, rewrite adjustment software back to
user firmware using the writing software. (See the help
of the software for information on how to write it.)
10. After rewriting user software, check the checksum (hold
down the [N.R.] and [MIC/CAR] keys and press the
[POWER] key. Menu No.125). Then , perform all reset.
Notes :
1. When adjustment software is loaded and the main unit is
turned ON, a beep sounds to indicate the adjustment
mode. This does not indicate a failure.
When any key (except [PF] key) is pressed after a frequency is displayed, the beep stops.
2. Do not return the TS-2000/X that contains adjustment
firmware to the user.
■ Adjustment mode operation procedure
1. Start the adjustment mode.
Hold down the [N.R.] and [MIC/CAR] keys and press the
[POWER] key. The adjustment mode is set and a menu
number is displayed below the M.CH on the main band
side (left) of the display.
MENU No.
2. Select adjustment mode menu No.
Turn the [MULTI CH] knob to change the menu No.
3. Change adjustment mode setting data.
Setting data can be changed with [+] or [–] key.
4. Write adjustment mode data.
Press [+] or [–] key on the main unit or [UP] or [DOWN]
key on the microphone on menu No. 124.
5. Cancel adjustment mode.
Press the [CLR] key to return to the normal VFO mode.
