CIRCUIT

DESCRIPTION

1.

Phase

Locked

Loop

The

130

MHz

signal

from

Q27

passes

through

the

buffer

circuit

Q28

and

is

then

divided

into

a

synthesizer

output

by

Q11

and

a

loop

output

by

Q12

respectively.

The

output

from

Q12

is

mixed

with

the

local

oscillator

output,

tripled

by

Q6,

D21

and

Q20

to

obtain

IF

frequency.

The

IF

output

is

amplified

by

Q19

and

is

fed

to

Q15

where

the

output

is

frequency

divided

as

specified

by

the

BCD

code

and

compared

with

the

10

kHz

reference

frequency

(1/1024

of

10,240

MHz)

The

DC

output

thus

obtained

passes

through

the

low-pass

filter

to

control

the

VCO

vari-cap

diode

182208

D26.

The

output

from

Q26

controls

the

transmit

frequency

bandwidth.

When

the

signal

is

un-

locked,

output

is

shut

off

by

Q17

and

indicated

by

Q18.

Q16

shuts

off

output

when

the

rotary

switch

is

between

channel

setting

positions.

kHz

Circuit

In

the

PLL

circuit,

the

reference

frequency

is

controlled

in

10

kHz

steps.

The

+5

kHz

signal

is

controlled

by

varying

the

local

oscillator

crystal

frequency

vari-cap

diode,

so

the

frequency

division

remains

unchanged

even

when

the

+5

kHz

circuit

is

operated.

The

memory

circuit

also

includes

the

same

bit

and

func-

tions

even

when

the

+5

kHz

circuit

is

operating.

frequencies

can

pressed,

the

is

fed

directly

to

Is

effected

by

latching

each

is

stored

by

pressing

The

stored

information

remains

the

same

unless

the

is

pressed

once

again.

Selection

of

is

accomplished

by

is

obtained

by

pressing

RECEIVER

UNIT

The

passes

through

and

is

fed

to

the

2-stage

circuit

and

(MOS

amplifier.

This

signal

is

further

fed

to

the

MOS

FET

where

it

ig

converted

to

a

10.7

signal.

The

signal

thus

converted

passes

through

the

2-stage

filter

and

is

fed

to

the

2nd

mixer

where

it

is

converted

to

a

455

signal.

The 2nd

iF

signal

from

the

455

kHz

ceramic

filter

passes

through

the

limiter

circuit

where

it

is

converted

to

an

AF

signal

by

the

ceramic

discriminator.

This

signal

is

amplified

by

the

audio

power

amplifier

to

drive

the

speaker.

The

receiver

unit

includes

a

circuit.

This

circuit

picks

up

the

in

the

squelch

signal

from

the

which

is

amplified

and

rectified

to
