X1 is VCTCXO, which provide stable oscillator of 12.8 MHZ to PLL IC.
Frequency adjustment is provided by VR1.
.Voltage controlled oscillator module(VCO)
The module produces carrier frequencies during transmit and local oscillator frequencies
During receive.
The module contains one VCO and three outputs. One for producing carrier frequencies during
Transmit and one for producing the local oscillator frequency during receive and the other
Output is for PLL IC(IC1) Fin.
PAGE5
The module also has Rx and TX powerline filters.
Transistor Q301 is configured as a 5v power supply ripple filter. The filter reduces the
noise on the carrier and local oscillator signals.
The VCO comprises Q302, Coil L304, and varactor D301 D304 and is configured
as a Colpits oscillator. D301 D304 produces a change in frequency with a change in DC voltage
and is controlled by the tuning voltage signal present at the cathode. The local oscillator
programmable dividers. DATA is received by IC1 at pin 10 from pin 11of IC3.
The RF signal at the collector of Q302 is applied to an amplifier/buffer Q305.The amplified
Signal from Q305 passes to the prescaler ,IC1 pin8 .The RF signal at the collector of Q302 also
Drives the cascode amplifier/buffer formed by Q304 .
When D201 is forward biased (TX ON) , carrier frequencies at the collector of Q304 pass to the
Power amplifier and harmonic filter. When D303 is forward biased (RX) , local oscillator
Frequencies at the collector of Q304 pass to the first mixer . VC1 adjusts the tuning
RX and TX power line filters
VCO
Voltage of the VCO to the correct operating point.
The reference frequency from the TCXO, at 12.8 MHZ , is connected to pin 1 of IC1(MB1504)
REFDIV divides the 12.8 MHz to produce a reference frequency (Fr) of 5 or 6. 25 kHz
dependent upon channel spacing selected. VARDIV divides the prescaled VCO frequency
to produce a variable frequency (Fv). Fv and Fr are fed to the phase detector.
When Fv=Fr, the phase detector output (pins 15 and 16,IC1) produces narrow negative pulses
And Fv and Fr pulse widths are identical. When Fv〉Fr pin 15 (V) pulses negative with pin 16
(R) remaining high. When Fv〈Fr pin 16 (R) pulses negative with pin 15(V) remaining high.
The signal at pin 15 and 16 is smoothed the loop filter and applied to the VCO.
PLL IC
Phase detector
The out-of-lock detector produces a series of logic level pulses when the loop is out of lock at
pin 7 of IC1.The pulses at pin 7 of IC1 are buffered by Q6 and then integrated by R17 and
C19. The product of the integrating circuit is fed to Base of Q201.
Out-of-lock detector
PAGE6
Charge Pump and Loop Filter
Transistors Q2,Q4,Q10 , and associated resistors and capacitors form the charge pump and loop
Filter . The phase detector output from IC1 pins 15 and 16 are combined by the charge pump to
Produce a 0 to 8V tuning voltage signal.
The signal is filtered by the loop filter (R13,C15 and C20) to remove any residual reference
Frequency harmonics from the signal.. After filtering the signal is applied to the voltage controlled
Oscillator module.
DC REGULATOR

Tuning voltage for the VCO . A wide voltage range is required to allow for the wideband operation
Of the radio .

PAGE7
Buffer
When the radio is in transmit mode the diode D201 is forward biases enabling the
modulated RF signal from the VCO to pass to the buffer/pre-amplifier Q204 and
associated components.
The output signal is passed from Q204 to Q205 via a matching network consisting of
Inductor L201 and C208.
PA module
The signal is then amplified for transmission by Q207, which is a power amplifier module.
Low pass filter
The amplified RF signal is passed through the stripline coupler and is fed to the
harmonic low pass filter, comprising L213 to L214 and C232-C234 and then to the antenna
connector (ANT).

and second local oscillator.
The 455KHz IF signal is output from pin 3 and is applied to a 455KHz band-pass filter CF1.
The output of CF1is passed via pin 5 to a high gain IF amplifier coupled to the
adjustable quadrature detector T2.Any detected signal is produced at pin 9 of
IC101 and applied to the Receiver Audio Circuit and the Mute (Squelch) Circuit.
