CIRCUIT DESCRIPTION
The block diagram of the TR-7400A is shown in page
*
The TR-7400A incorporates newly developed circuit
technique such as PLL frequency synthesizer as the local
oscillator.
PLL CIRCUIT
The block diagram is given in Fig. 1.
The circuit is outlined below. The outputs of the VCO
and LOCAL OSC are mixed together and converted to
5.37 ~ 9.36 MHz signal and divided to 1/537 ~ 1/936
with the programmable counter to obtain 10 kHz output.
The phases between the 10 kHz output and another 10
kHz signal obtained by dividing 5.12 MHz REF OSC out-
put to 1/512, are compared. And the phase difference, if
any, is fed back to the VCO to lock it. The stability of
this function is determined by the LOCAL OSC and REF
OSC, and the stability of the VCO is virtually equal to
that of those oscillators which consist of crystal oscillators.

CIRCUIT DESCRIPTION
VCO UNIT (X50-1370-10)
The VCO is a Colpitts type oscillating circuit of Q7
and its frequency varies with the control voltage applied to
varicap diode D1. This circuit is strictly stabilized against
changes in temperature and power source voltage to im-
prove the C/N of its output and prevent unlocking.- The
VCO’'s output is passed through buffer Q6, amplified by
Q12 and applied to MIX through D6 and D7 for both
reception and transmission.
In the LOCAL OSC, two quartz crystals for 0 and 5
kHz are switched with a switching diode. O8 performs over-
tone oscillation and its Output is tripled in 09 to 127.930
and 127.935 MHz which are applied to MIX stage. The
MIX circuit mixes the output and the VCO’s output ampli-
fied by Q5, and its output is passed through a m-type LPF
to deliver IF output of 5.37 ~ 9.36 MHz.
The output is amplified by the wide-band amplifier
of Q1 to QO3 and applied to the programmable counter.
Q13, which turns on and off VCO amp Q12, is a protective
circuit in order to prevent emission of spurious radiation
occurring when the PLL circuit fails to lock and the VCO
runs away. This circuit is automatically reset when the
PLL begins to work properly because it is not involved in
the phase lock loop. D8 provides a certain time delay
when Q13 is turned off, so Q13 does not operate during
the transient state before the VCO is locked, though the
indicator works. This contributes to reduce noise.

PD UNIT (X50-1380-10)
Q6 serves as the interface and buffer amp for IC8.
The waveform of its IF output is shaped in IC8 and its
output frequency is divided to 10 kHz by the program-
mable counter consisting of IC5 to 12 and the resulting
signal is applied to MC4044P of IC4. While IC1 generates
5.12 MHz signal which is divided to 1/2 by the flip-flop
circuit involved in IC1. The resulting frequency is further
divided to 1/16 in IC2, IC3 and 10-kHz output signal is
applied to MC4044P of IC4.
The MC4044P consists of two PDs (phase detectors),
charge pump and amplifier. Fig. 3 shows the block diagram.
Passing through the charge pump and active filter, the out-
put of No. 1 PD becomes the control voltage to be applied
to the varicap of the VCO. The active filter consists of
Q1 to 3 to keep the VCO away from phase comparator
noise. No. 1 PD, a digital phase comparator, contains a
sequential logic circuit which operates at the edge of decay
of signal coming to enter R and V terminal. Its state be-
comes as shown in Fig. 2 after a certain time. When R is
not equal to V (unlocked state), D1 or D2 is turned on and
Q5 turns on O04 to switch off Q13, VCO amp driver, so
that spurious emission which might occur if the PLL fails
to lock is prevented.

CIRCUIT DESCRIPTION
PROGRAMMABLE COUNTER AND TX-OFFSET
CIRCUITS
These circuits, consisting of |C5 to 1C12, are basically
a MODULO-N PROGRAMMABLE counter of IC5 to IC7
added with an EXTENDER consisting of a D-flip-flop of
1C10 and a logic circuit of 1C8, 9, 11 and 12. It belongs
to the high-speed scaling method. Fig. 4 shows the opera-
tion of the circuits. The operation is simply described
below. A division ratio is preset in the MC74416 of IC5
to IC7 with a BCD code. The idvision ratio preset is be-
tween 400 and 799 in relation to digital indication (144.00
~ 147.99). While, since the IF signal entering the MC
74416 is 5.37 ~ 9.36 MHz to eliminate beat interference
in reception, the division ratio must be 537 ~ 936 actually.
For this purpose the gate, No, serves to raise the division
ratio by 137. The gate circuit, U and D, shifts frequency
by +600 kHz for repeater operation which is equivalent
to the division ratio of 137 + 60. MC74416 is a decrement-
BCD (N = 400 ~ 799)

ing counter which counts in the order of 0, 4, 3, 2, 1, 0
(5); "453; receiving input pulses, assuming that preset
value is 5 and PE is ‘’0” (L level).
But output becomes ‘1’ (H level) only when the
count is 0. It means that five input pulses make one out-
put pulse and the frequency is divided to 1/5. With three
ICs connected in cascade, the division ratio can be raised up
to 999. IC10 is a high speed D-flip-flop which improves
the operating frequency of MC74416, 8 MHz (min.), by
abouta factor of two or more with the aid of gates A and B.
Fig. 4 shows the case where the least significant digit
of the actual division ratio, Ns, is 7. Although resetting
should be done at the rise of input pulse and presetting
should be done at the decay of the input pulse when the
count has become three, the level at A is set to L at the
count of five and it becomes the output of 1C10-1 at the
next pulse. This output (Q1) resets the MC74416 and
presets it to N at the same time, but counting is not per-
formed since PE remains at the L level during the next

input pulse and it is reset. The operating frequency has
been improved because resetting and presetting are done
in one cycle of input pulse but not in half acycle, and the
delay time, t2, of the high speed D-flip-flop in 1C10 is
much smaller than the delay time, t1, from IC5, 6 and
7 and logic circuit to point A.
Next, operation is explained in relation to the TX off-
set switch setting.
1 +600
During reception, this is the same as in (2). During
transmission, SR1 is turned on and becomes U*in Table 2.
Gate U therefore opens and gates No and D are closed.
At this setting, Ns = N + 197 (137 + 60), and it operates
as an extender when IC5, IC6 and IC7 take code 8, O and
5 respectively, to perform division of-N + 197.
2 No (SIMP)
(F) and (G) make up No in Table 2. Gates No and U
open and gate D is closed. At this setting, the relation,
Ns = N + 137, holds between preset value N and actual divi-
sion ratio Ns. It is enoughto decrement the counter after
division of N (decrementing) has completed and perform
resetting and presetting just when the count has become
137. For this purpose, 1C5, 1C6 and IC7 do not take code
8, 6 and 3 respectively (as already described), but it
operates as an extender at code 5 and performs division
of N+ 137. Since the gate is of code 197 (137+ 60), the
extender operates before this code triggers the circuitry.
3 -—600
During reception, SR2 is turned on as in (2). During
transmission, gates No, U and D open as D in Table 2.
At this setting, Ns = N + 77 (137 — 60), it operates as an
extender to perform division of N + 77 when IC5, 1C6 and
1C7 carry code 9, 2 and 5 respectively. At this time, the
extender operates at code 77 even when all gates are open.
Table 1 shows the case of N = 400 (144.00 MHz).

Fig. 5 TONE SQUELCH Circuit
TONE SQUELCH CIRCUIT
Fig. 5 shows the circuit. The tone squelch circuit
employed in this equipment is the so-called CTCSS (con-
tinuous tone controlled squelch system). Tone signal of a
certain frequency is superimposed with audio signal at the
transmission side, which is separated at the reception side
to drive the squelch circuit. When set to SQU (tone squelch)
as shown in Fig. 5, a voltage is applied to TSB1 and TSB2.
When no signal is received or signal received does not have
tone component, Q20 and 21 remain off and no sound is
reproduced since the voltage of TSB2 is applied to the
base of Q13 through D414 and the AF circuit is turned off.
When signal including tone component is received, the tone
signal separated from discriminator output with Q19, LPF
and amplifier, is applied to an active filter. The active filter
which serves to the tone frequency and Q11 give steep
characteristics at the frequency. It selects tone output
equal to the active filter and its output passes through D11
(on during reception) and is detected in D12 and 13. It
turns on Q20 and then Q21 and turns off Q13 and the AF
circuit (Q14) operates to reproduce sound from speaker.
In the AF circuit, an active type high-pass filter of Q24
and 25 cuts off tone signal output to amplify audio signal
alone. During transmission, Q22 is turned on, and the
active filter and Q11 form an oscillating circuit to deliver
output with the same frequency as of the active filter.
This output is passed through VR3 and modulated in TX
unit together with audiosignal. The maximum frequency +
deviation for audio signal is +5 kHz and that for tone com-
ponent for tone squelch is 0.5 kHz, which results in a
ratio of about —20 dB. This would result in buzzing sound
when unmodulated signal is received, but a high-pass filter
of 300 Hz in cutoff frequency corporated in the equipment
reduces the tone level to prevent buzz. Operation is the
same even in the SUB (sub-audible’ since a voltage is applied
to TSB1, and sub-audible control is performed.

VCT CIRCUIT
The equipment incorporates a VCT circuit at the out-
put side of the transmission mixer to improve spurious
radiation and output levels in the wide range from 144 to
148 MHz. Varicaps D2, 3 and 4 are connected to tuning
coils L11, 12 and 13 through temperature compensation
capacitors. Voltages divided from common 9V (C9) with
R62 and 61 (145.5 MHz), VR61 (144.5 MHz) VR62 (146.5
MHz) and VR63 (147.5 MHz) and switched with a MHz
switch are applied to D2, 3 and 4.
FINAL CIRCUIT
The output of the TX unit (about 1.4 W, 50-ohm)
load) is amplified to about 10 W (50-ohm load) by Q1 of
the PA unit and to about 35 W (50-ohm load) by O2 and
delivered to the ANT terminal by way of an ANT switching
diode and a LPF. To protect the final transistor (Q2), the
input power to Q2 is limited by controlling the collector
voltage of the driver (015 of TX unit and Q1 of PA unit)
by detecting SWR of antenna with O3, 10 and 11. When
power is low, the circuit is used to reduce the voltage across
the SB terminal with VR5.
Large aluminum die-cast heat sinks in combination
with Motorola transistors, MRF208 and 2N6083, ensure
high reliability.
