OPERATION INSTRUCTIONS
Having properly installed your batteries and hooked-up the antenna, you are now ready to operate your radio for
optimum reception and voice transmission.
Turn the power “ON” with ON/OFF switch.
Set the desired channel.
Adjust the squelch control knob to reduce any undesirable background noise when no signal is being received.
To do this, select a channel where no signal are present, or wait until signals cease on your channel. Then, rotate
the squelch control knob clockwise to a point where the background noise disappears.
Note: When the squelch is set properly, the speaker will remain quiet until a signal is received. In
order to receive weak signals, do not set the squelch too high.
Adjust the volume to the desired listening level.
To Transmit
Press and hold the push-to-talk button. Speak slowly and clearly in a normal voice two to three inches from the
microphone. A buit-in modulation control circuit will automatically adjust the microphone input level. There is no
need to speak loudly.
To Receive
Release the push-to-talk button.

THEORY OF OPERATIONS
TRANSMITTER
A. RF Amplification
The output of double AMP Q14 is fed through tuning IFT L8 to the base of pre driver AMP Q15. The output is
then supplied through tuning circuit L9 to RF driver AMP Q16. The output of Q16 is supplied with tuning circuit
L10 and C116,C67,C95 and goes to the base of final RF AMP Q17. The output of Q17 is supplied to the antenna
through L-C tuning circuit.
B. Circuit for Suppression of Spurious Radiation
The tuning circuit between the output of final AMP Q17 and antenna, 4-stage “PHI” network L13,
C142,C71,C72,L14,C74,C75,L15,C77,C78,L16,C79,C80,L24 serves as a spurious radiation suppressor . This
network also serves to match the impedance between TX power AMP Q17 and the antenna.
C. Circuit for Limiting Power
After finished all alignment, the constant voltage supply circuit limits the available power 4 W or slightly less.
RV4 and corresponding three transistors control supply voltage of RF amplifier and other circuits.
Tune all the trimmer parts for maximum indication of RF power meter and adjust RV4 to make 4 w indication of
RF power meter.
The tuning is adjusted so that the actual power is from 3.5 to 4.0 W. There are no other additional controls for
adjusting the TX output power.
D. Modulation Control
a. FM
The mic input is fed to mic audio amplifier IC KIA324 which drives modulation varicap diode D403 in the VCO
circuit. RV1 limits the incoming modulation audio levels to inhibit over modulation. While reading the modulation
factor on the modulation analyzing equipment, adjust RV1 shall not exceed +-1.7 KHz/Dev. After 20 dB up from
1.25 KHz/1.2 KHz/Dev. Audio level
b. AM
Modulation signals are filtered with RC network and goes to the audio power AMP IC IC103 to make nominal
signal level to achieve wanted modulation. To control incoming audio signal, diode D7 and corresponding ALC
circuit limits the modulation shall not exceed +/-90% adjust RV3 +/-90% modulation under 1.0 KHz AF 60%
mod plus 20 dB of audio signal.

E. Receiver
CB receiver is dual conversion supper-heterodyne type with the first IF 10.695 MHz and second IF 455 KHz.
Receiver is separated two blocks, 1
st
IF section and 2nd IF section. The PLL synthesizer supplies first local
frequency 16.270 ~ 16.710 MHz.(for EU) and 16.90625 MHz ~ 17.29625 MHz (for UK) With the provided first
local frequencies to Q2,Q3 mixes the incoming RF signal to generate first IF signal. Mixed signals were filtered
with the XF1 (10.695 MHz) crystal filter and other tuning circuits. Output signal of mixer is filtered with CF1(455
KHz ceramic filter). The 455 KHz signal from the 2
nd
IF filter was amplified and limits internaly. After amplification
the signals fed the quadrature detector loop L20. Then we can see the recovered audio signals on Pin 9 for FM
of IC7. With the amplitude of recovered signals, Q10 serves as an audio amplifier. For AM signal Will be pass
filter CF1 and induced to Q6, Q7 respective and detected to voice signal by D5.

1. INTRODUCTION
The frequencies for transmitter and receiver first local frequencies are all derived from a single 4.0 MHz crystal
by means of a phase locked loop. The first local oscillator frequencies are 26.965 MHz (CH 1) to
27.405MHz (CH 40) for EU and 27.60125 MHz (CH 1) to 27.99125 MHz (CH 40) for UK . The second local
frequency is fixed at 10.240 MHz to generate second IF 455 KHz.
The VCO operating frequency for the receiver is 37.660 MHz (CH 1) to 37.560 MHz (CH 40) as the first local
oscillator, injected through the buffer AMP Q411 into the first fed balanced mixer Q2 and Q3.
2. BASIC SYNTHESIZER SCHEME
The crystal frequency (4.000 MHz) is divided by 800 times to make 5 KHz which is fed to one side of the phase
detector. The VCO output is divided by a programmable divider, and fed to other side of the phase detector of
IC4. The feedback loop is closed by passing the phase detector output through an active low pass filter and using
the output to control the VCO frequency through varicap diode D402,D403
Under locked conditions, both of phase detector input signal must be indential at 5 KHz. The VCO frequency is
then given by:
FVCO / N = 0.005 MHz or FVCO = 0.005 x N MHz
Since “N” is an integer, the VCO frequency can be stepped up with 5 KHz increments. By suitable choice of “N”
the desired output frequency can be obtained.

crystal oscillator frequency and maintaining the same percentage accuracy.

3. DESCRIPTIONS OF EACH BLOCK
A. Introduction
The synthesizer is implemented with the following
Components:
PLL IC (IC4)
X-TAL (X2)
15
Model No: M760 Plus
Customer: INTEK Rev No: A
VCO, VARICAP DOIDE (D402,D403)
IC5 is a cmos LSI that includes most of PLL block and driver, the Q403-Q406,Q408, C412, C421, C416, C417
and L17, Varicap diode D402,D403 are clapp oscillator circuit to operate as a VCO. Q406 is a switching
transistor to connect or disconnect the tuning capacitor in the VCO oscillator tank circuit for transmitter or
receiver. Q411 works as a buffer AMP for RX local frequencies (38MHz) and TX generating frequencies (26
MHz).
B. Reference frequency
The crystal, X2 (4.000 MHz) and other components at IC4 can make a reference frequency oscillator with internal
amplifier.
C. VCO
Q408 and surrounding parts are consisting a clapp oscillator works as a VCO . the VCO can be oscillate over the
required of 25.610MHz to 41.115 MHz
D. Phase detector and VCO control
The detector is a digital phase comparator which compares the phase of the reference signal with programmable
divider output square waves and develops a series of pulses whose DC level depends on the phase error of each
signal.
E. Transmitter/Receiver buffer AMP
Output signal of Q408 is fed into buffer AMP Q411,
F. Switching of tuning capacitor in VCO
The VCO circuit must tune with a wide rang of frequencies 25.610MHz to 30.15MHz for transmitter and
36.305~41.115 MHz for receiver. To comply above rang of VCO, the tuning capacitance should switched for
transmission or reception.
G. Receiver local oscillator outputs
First Mixer:
The secondary output signals is injected to the sources of 1
st
mixer Q2,Q3 in the 1st IF mixer
section
Second Mixer:
The output of 10.24 MHz oscillator circuit with XF1 is injected into the IF IC internally. Incoming IF
signal and 10.24 MHz are mixed inside the IF IC to extract 2
signals are recovered with the way of quadrature detector, AM signals are recovered with envelope

detector.
4. FREQUENCY STABILITY
LET : Fo = Crystal oscillator frequency
Fr = Phase detector reference frequency
Fvco = VCO frequency
Ft = Transmit frequency
Then : Fr = Fo/800
And under locked conditions : Fr = Fvco / N
WHERE, “N” is the programmable divider divide ratio.
THEN : Fvco = N X Fr
From which it can be seen, the percentage error in Ft is the same as the percentage error in Fo. The stability of the
crystal oscillator is determined primarily by the crystal itself and having lesser deviation by the active and passive
components of the oscillator. The choice of crystal and component is such that the required frequency stability is
maintained over the required voltage and temperature rang.
