CIRCUIT

ANALYSIS

The

ICOMs

are

enclosed

in

a

dust-

proof,

RF

shielded

can

with

the

type

ICOM

(5C-ICOM, EC-ICOM,

or

2C-ICOM)

printed

on

the

top

of

the

can.

Access

to

the

oscil~

lator

trimmer

is

obtained

by

prying

up

the

plastic

tab

on

the

top

of

the

can.

The

tabs

can

also

be

used

to

pull

the

ICOMs

out

of

the

radio.

Frequency

selection

is

accomplished

by

switching

the

ICOM

keying

lead

(termi-

nal

6)

to

A-

by

means

of

the

frequency

se'Iector

switch

on

the

control

unit.

In

single-frequency

radios,

a

jumper

from

H9

to

HlO

in

the

control

unit

connects

terminal

6

of

the

ICOM

to

A-.

The

oscil-

lator

is

turned

on

by

applying

a

keyed

+10

Volts

to

the

external

oscillator

load

resistor.

RF

bypassing

is

provided

for

all

unused

keying

leads

on

eight

frequency

radios.

On

two

frequency

radios,

the

six

unused

keying

leads

are

shorted

to

ground.

r--------------

CAUTION

----------------~

All

ICOMs

are

individually

compen-

sated

at

the

factory

and

cannot

be

repaired

in

the

field.

Any

attempt

to

repair

or

change

an

ICOM

fre-

quency

will

void

the

warranty.

In

standard

5

PPM

radios

using

BC-ICOMs,

at

least

one

5C-ICOM

must

be

used.

The

5C-ICOM

is

normally

used

in

the

receiver

Fl

position,

but

can

be

used

in

any

transmit

or

receive

position.

One

SC-ICOM

can

pro-

vide

compensation

for

up

to

15

EC-ICOMs

in

the

transmit

and

receiver.

Should

the

5C-ICOM

compensator

fail

in

the

open

mode,

the

EC-ICOMs

will

still

maintain

2

PPM

frequency

stability

from

0°C

to

55°C

(+32°F

to

131°F)

due

to

the

regulated

compensation

voltage

(5

Volts)

from

the

10-Volt

regulator

IC.

If

desired,

up

to

16

5C-ICOMs may

be

used

in

the

radio.

The

2C-ICOMs

are

self-compensated

at

2

PPM

and

will

not

provide

compensation

for

EC-ICOMs.

Oscillator

Circuit

The

quartz

crystals

used

in

ICOMs

exhibit

the

traditional

"S"

curve

character-

istics

of

output

frequency

versus

operating

temperature.

At

both

the

coldest

and

hottest

tem-

peratures,

the

frequency

increases

with

increasing

temperature.

In

the

middle

temperature

range

(approximately

0°C

to

+55°C),

frequency

decreases

with

increasing

temperature.

Since

the

rate

of

change

is

nearly

lin-

ear

over

the

mid-temperature

range,

the

out-

put

frequency

change

can

be

compensated

by

choosing

a

parallel

compensation

capacitor

with

a

temperature

coefficient

approximately

2

equal

and

opposite

that

of

the

crystal.

Figure

2

shows

the

typical

performance

of

an

uncompensated

crystal

as

well

as

the

typical

performance

of

a

crystal

which

has

been

matched

with

a

properly

chosen

compen-

sation

capacitor.

Characteristics

At

temperatures

above

and

below

the

mid-range,

additional

compensation

must

be

introduced.

An

externally

generated

com-

pensation

voltage

is

applied

to

a

varactor

(voltage-variable

capacitor)

which

is

in

parallel

with

the

crystal.

A

constant

bias

of

5

Volts

(provided

from

Regulator

IC

U901

in

parallel

with

the

compensator)

establishes

t.he

varactor

ca-

pacity

at

a

constant

value

over

the

entire

mid-temperature

range.

With

no

additional

compensation,

all

of

the

oscillators

will

provide

2

PPM

frequency

stability

from

0°C

to

55°C

(32°F

to

131°F).

Compensator

Circuits

Both

the

SC-ICOMs

and

2C-ICOMs

are

temperature

compensated

at

both

ends

of

the

temperature

range

to

provide

instant

fre-

quency

compensation.

An

equivalent

ICOM

circuit

is

shown

in

Figure

The

cold

circuit

does

not

operate

at

temperatures

above

0°C,

When

the

temperature

drops

below

0°C,

the

circuit

is

activated.

As

the

temperature

decreases,

the

equivalent

resistance

de-

creases

and

the

compensation

voltage

in-

creases.

The

increase

in

compensation

voltage

decreases

the

capacity

of

the

varactor

in

the

oscillator,

increasing

the

output

frequency

of

the

ICOM.

4.

The

divider

consists

of

two

J-K

flip-flops

con-

nected

as

a

binary

counter.

When

the

transmitter

is

not

keyed

(no

ICOMs

on),

QlOl

is

saturated

(turned

on)

with

its

collector

voltage

near

zero.

Key-

ing

the

transmitter

starts

one

of

the

ICOMs,

and

its

output

cuts

QlOl

on

and

off

once

each

cycle.

As

QlOl

turns

off

during

each

cycle,

the

drop

in

collector

voltage

causes

the

left

flip-flop

to

change

state.

Assume

the

flip-flop

was

in

the

"O"

state

(the

output

at

"Q"

near

A-).

The

first

cycle

of

the

oscillator

output

causes

it

to

switch

to

the

"1"

stage

(output

at

"Q"

at

approxi-

mately

5

Volts).

The

second

cycle

will

cause

the

flip-flop

to

switch

back

to

the

"0"

state.

Therefore,

it

requires

two

oscillator

cycles

to

switch

the

left

flip-

flop

through

one

complete

cycle

from

"O"

to

"1"

and

back

to

"0".

When

the

left

flip-flop

switches

from

"1"

to

"0",

it

causes

the

right

flip-flop

to

change

state.

It

requires

two

cycles

of

the

left

flip-flop

to

switch

the

right

flip-flop

from

"O"

to

"1"

and

back

to

"0".

Therefore,

four

cycles

of

the

oscillator

out-

put

are

required

for

each

cycle

of

output

from

9

of

UlOl.

4

If

UlOl

was

operating

into

a

pure

resistive

load,

its

output

would

be

a

square

wave.

However,

the

modulator

circuit

pre-

sents

a

tuned

load

to

the

IC,

so

that

har-

monics

are

filtered

out

and

the

waveform

at

the

junction

of

Cl02

and

Cl03

(modulator

input)

is

essentially

a

sine

wave

at

one-

fourth

the

oscillator

frequency.

The

out-

put

of

the

frequency

divider

is

coupled

through

DC

blocking

capacitor

Cl02

to

the

first

modulator

stage.

PHASE

MODULATORS,

AND

The

first

phase

modulator

is

varactor

(voltage-variable

capacitor)

CVlOl

in

series

with

tunable

coil

LlOl.

This

network

appears

as

a

series-resonant

circuit

to

the

RF

out-

put

of

the

oscillator.

An

audio

signal

applied

to

the

modulator

circuit

through

blocking

capacitor

Cll5

varies

the

bias

of

CVlOl,

resulting

in

a

phase

modulated

out-

put.

A

voltage

divider

network

(Rl08

and

Rl09)

provides

the

proper

bias

for

varactors

CVlOl,

CV102

and

CV103.

The

output

of

the

first

modulator

is

coupled

through

MODULATION LEVEL ADJUSTMENT

The

MOD

ADJUST

(Rl27)

was

adjusted

to

the

proper

setting

before

shipment

and

should

not

normally

require

readjustment

.

This

setting

permits

approximately

75

%

modulation

for

the

average

voice

level.

The

audio

peaks

which

would

cause

overmodulation

are

clipped

by

the

modulation

limiter.

The

limiter,

in

co

njunction

with

the

de-emphasis

network,

instan-

tan

e

ously

limits

the

slope

of

the

audio

wave

to

th

e

modulator,

thereby

preventing

over-

modulation

while

preserving

intelli

g

ibility.

PA

POWER

INPUT

For

FCC

purposes,

the

PA

powe r

input

can

be

determined

by

measuring

the

PA

supply

voltage

and

PA

current,

and

using

the

following

formula:

Pi

=

PA

voltage

x

PA

current

wher

e :

Pi

is

the

power

input

in

Watts,

PA

voltage

is

measured

with

Test

Set

Model

4EX3All

in

Position

G

on

the

15-Volt

range

(read

as

15

Volts

full

scale),

and

with

the

polarity

switch

in

the

(-)

position.

With

Test

Model

4EX8Kl2,

use

the

B+

position

and

the

1-Volt

TEST

PROCEDURES

These

Test

Procedures

ar~

designed

to

assist

you

in

servicing

a

transmitter

that

is

operating--

but

not

properly,

Problems

encountered

could

be

low

power

output,

tone

and

voice

deviation,

defec-

tive

audio

sensitivity,

and

modulator

adjust

~on

trol

set

too

high.

Once

a

defect

is

pin-pointed,

refer

to

the

~'Service

Check"

and

the

addi

tiona!

corrective

measures

included

in

the

Transmitter

Troubleshooting

Procedure.

Before

starting

with

the

Transmitter

Test

Procedures,

be

sure

the

transmitter

is

tuned

and

aligned

to

the

proper

operating

frequency.

CAUTION

-------------

Before

bench

testing

the

MASTR

II

Mobile

Radio,

be

sure

of

the

output

voltage

characteristics

of

your

bench

power

supply.

To

protect

the

transmitter

power

output

transistors

from

possible

instant

des-

truction,

the

following

input

voltages

must

not

be

exceeded:

Transmitter

unkeyed:

20

Volts

Transmitter

keyed

(50

ohm

resistive

load):

18

Volts

Transmitter

keyed

(no

load

or

non-resistive

load):

15.5

Volts

These

voltages

are

specified

at

the

normal

vehicle

battery

terminals

of

the

radio

and

take

the

voltage

drop

of

standard

cables

into

account.

The

voltage

limit

shown

for

a

non-optimum

load

is

for

"worst

case"

conditions.

For

antenna

mismatches

likely

to

be

encountered

in

practice,

the

actual

limit

will

approach

the

18

Volt

figure.

Routine

transmitter

tests

should

be

performed

at

EIA

Standard

Test

Voltages

(13.6

VDC

for

loads

of

6

to

16

amperes;

13.4

VDC

for

loads

of

16

to

36

amperes).

Input

voltages

must

not

exceed

the

limits

shown,

even

for

transient

peaks

of

short

duration.

Many

commonly

used

bench

power

supplies

cannot

meet

these

requirements

for

load

regulation

and

transient

voltage

suppression.

Bench

supplies

which

employ

"brute

force"

regulation

and

filtering

(such

as

Lapp

Model

73)

may

be

usable

when

operated

in

parallel

with

a

12-Volt

automotive

storage

battery.
