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 Q201 is fed through tuning T203 and T204 to the base of pre driver AMP Q202. The
output is then supplied to RF driver AMP Q203. The output of Q203 is supplied with tuning circuit L204 and C214,
C215, C216 and goes to the base of final RF AMP Q204. The output of Q204 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 Q204 and antenna, 5-stage “PHI” network C221, C219, C220,
L206, C223, C245, L207, C241, C228, C240, L208, C242, C230, C229, L209, C234, C233, C232, L210, C243,
C235, C236 serves as a spurious radiation suppressor . This network also serves to match the impedance
between TX power AMP Q204 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.
RV501 and corresponding three transistors Q509, Q502, Q501 control supply voltage of RF amplifier and other
circuits.
Tune all the trimmer parts for maximum indication of RF power meter and adjust RV501 to make 4 w indication
of RF power meter.
The tuning is adjusted so that the actual power is from 3.8 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 audio amplifier IC KIA324 which drives modulation varicap diode D302 in the VCO circuit.
RV701 limits the incoming modulation audio levels to inhibit over modulation. While reading the modulation factor
on the modulation analyzing equipment, adjust RV701 shall not exceed +/-1.6 KHz/Dev. After 20 dB up from
1.25 KHz/1.2 KHz/Dev. Audio level

Modulation signal is fed to audio amplifier IC KIA324 and goes to TX voltage regulate circuit Q509, Q502, Q501 to
make nominal signal level to achieve wanted modulation. To control incoming audio signal, R272 and
corresponding ALC circuit limits the modulation shall not exceed +/-60% adjust RV702 +/-60% 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 Q102,Q103 mixes the incoming RF signal to generate first
IF signal. Mixed signals were filtered with the CF101 (10.695 MHz) crystal filter and other tuning circuits. Output
signal of mixer is filtered with CF102 (455 KHz ceramic filter). The 455 KHz signal from the 2
nd
IF filter was
amplified and limits internally. After amplification the signals fed the quadrature detector loop T104. Then we can
see the recovered audio signals on Pin 12 for FM and Pin 13 for AM of IC1.

PLL CIRCUIT BLOCK DIAGRAM
1. INTRODUCTION
The frequencies for transmitter and receiver first local frequencies are all derived from a single 10.240 MHz
crystal by means of a phase locked loop. The first local oscillator frequencies are 16.270 MHz (CH 1) to 16.710
MHz (CH 40) for EU and 16.90625 MHz (CH 1) to 17.29625 MHz (CH 40) for UK. The second local frequency is
fixed at 10.240 MHz to generate second IF 455 KHz. During transmit, The VCO of the PLL operates 13.4825 MHz
(CH 1) to 13.7025 MHz (CH 40) for EU, 13.800625 MHz (CH 1) to 13.995625 MHz (CH 40) for UK the VCO
frequency goes to the double circuit Q201, T203, T204 which doubles the frequency to generate 26.965 MHz (CH
1) to 27.405 MHz (CH 40) for EU and 27.60125 MHz (CH 1) to 27.99125 MHz (CH 40) for UK
13.4825 MHz (CH 1) EU 26.965 MHz (CH 1)

13.995625 MHz (CH 40) UK 27.99125 MHz (CH 40)
The VCO operating frequency for the receiver is 16.270, 16.90625 MHz (CH 1) to 16.710, 17.29625 MHz (CH 40)
as the first local oscillator, injected through the buffer AMP Q302 into the first fed balanced mixer Q102, Q103.

2. BASIC SYNTHESIZER SCHEME
The crystal frequency (10.240MHz) is divided by 1800 times to make 2.5 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 Pin 11 of IC302. 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 D301.
Under locked conditions, both of phase detector input signal must be indential at 2.5 KHz. The VCO frequency is
then given by:
FVCO / N = 0.0025 MHz or FVCO = 0.0025 x N MHz
Since “N” is an integer, the VCO frequency can be stepped up with 2.5 KHz increments. By suitable choice of “N”
the desired output frequency can be obtained.

3. DESCRIPTIONS OF EACH BLOCK
A. Introduction
The synthesizer is implemented with the following
Components:
- PLL IC (IC302)
- X-TAL (X302)
- VCO, VARICAP DOIDE (D301)
IC302 is a cmos LSI that includes most of PLL block and driver, the Q301, C305, C306, C304, C301 and T302,
Varicap diode D301 are clapp oscillator circuit to operate as a VCO of the IC302. Q301 is a switching transistor to
connect or disconnect the tuning capacitor in the VCO oscillator tank circuit for transmitter or receiver. Q304
works as a buffer AMP for RX local frequencies (16 MHz) and TX generating frequencies (13 MHz).
B. Reference frequency
The crystal, X302 (4.50 MHz) and other components of IC302 can make a reference frequency oscillator with
internal amplifier.
C. VCO
Q301 and surrounding parts are consisting a clapp oscillator works as a VCO of IC302. the VCO can be oscillate
over the required of 13.4825 MHz to 17.29625 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 Q301 is fed into buffer AMP Q302,
F. Transmitter doubler
The output signals of Q302 goes to an amplifier with tuning circuit Q201, T203, T204 which doubles incoming 13
MHz signals.
G. Switching of tuning capacitor in VCO
The VCO circuit must tune with a wide rang of frequencies 13.4825 ~ 13.7025 MHz (EU), 13.800625 ~
13.995625 MHz (UK) for transmitter and 16.270~16.710 MHz (EU), 16.90625 ~ 17.29625 MHz (UK) for receiver.
To comply above range of VCO, the tuning capacitance should switched for transmission or reception.

H. Receiver local oscillator outputs
First Mixer:
The secondary output signals is injected to the sources of 1
st
mixer Q102, Q103 in the 1st IF mixer section
Second Mixer:
The output of 10.24 MHz oscillator circuit with X101 is injected into the IF IC internally. Incoming
IF signal and 10.24 MHz are mixed inside the IF IC to extract 2
nd
IF signal 455 KHz. FM,AM audio
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/1800
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.
