WARNING

----------------------------------------,

ii

Although

the

(5C-ICOM,

EC-ICOM

or

Access

to

the

oscillator

trimmer

is

obtained

through

a

hole

on

the

top

of

the

can.

Frequency

selectaon

is

accomplished

by

switching

the

ICOM

keying

lead

(terminal

6)

to

A- by means

of

the

frequency

selector

switch

on

the

control

unit.

In

single-fre-

quency

radios,

a

jumper

from

H9

to

HlO

in

the

control

unit

connects

terminal

6

of

the

!COM

to

A-.

The

oscillator

is

turned

on

by

applying

a

keyed

+10

to

the

exter-

nal

oscillator

load

resistor.

RF

bypassing

is

provided

for

all

unused

keying

loads

in

eight

radios.

In

the

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

EC-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

5C-ICOM

can

provide

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

crystals

used

in

ICOMs

ex-

hibit

the

traditional

of

output

frequency

versus

operating

temperature.

At

both

the

coldest

and

hottest

tem-

peratures,

the

frequency

increases

with

increasing

temperature.

In

the

middle

tem-

perature

range

(approximately

0°C

to

+55°C),

frequency

decreases

with

increasing

temper-

ature.

Since

the

rate

of

change

is

nearly

linear

over

the

mid-temperature

range,

the

can

be

compensated

by

choosing

FREQUENCY

DIVIDER

IC

The

output

at

of

the

selected

ICOM

is

coupled

through

buffer

amplifier

QlOl

to

frequency

divider

UlOl,

which

di-

vides

the

oscillator

frequency

by

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"

approxi-

mately

5

Volts}.

The

second

cycle

will

cause

the

flip-flop

to

switch

back

to

the

"O"

state.

Therefore,

it

requires

two

os-

cillator

cycles

to

switch

the

left

flip-

flop

through

one

complete

cycle

from

"0"

4

to

"1"

and

back

to

"0"•

When

the

left

flip-flop

switches

from

"1"

to

"O",

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

output

are

required

for

each

cycle

of

out-

put

from

9

of

UlOl.

If

UlOl was

operating

into

a

pure

re-

sistive

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,

&

MULTIPLIERS

The

first

phase

modulator

is

varactor

(voltage-variable

CVlOl

in

series

with

tunable

coil

LlOl.

This

network

appears

as

An

RF

from

is

applied

Turning

Q212

Adjust

R261.

Q215, Q216

Q217

operate

as

an

am-

plifier

chain

to

supply

voltage

to

the

col-

lector

of

Q204

(Ampl-1).

The

setting

of

R261

determines

the

voltage

applied

to

the

base

of

Q215.

The

higher

the

voltage

at

the

base

of

Q215,

the

harder

the

amplifiers

conduct,

supplying

more

collector

voltage

to

Q204.

The

lower

the

voltage

at

the

base

of

Q215,

the

less

collector

voltage

is

sup-

plied

to

Q204.

Reducing

the

supply

voltage

to

Q204

reduces

the

drive

to

Q205,

thereby

reducing

the

power

output

of

the

PA. The

power

output

can

be

adjusted

by R261

from

approximately

50

to

100

Watts

(75

to

100

Watts

at

25-30

MHz).

Temperature

protection

is

provided

by

Q213, Q214,

and

thermistor

RT201

which

is

mounted

in

the

PA

heatsink.

Under

normal

operating

conditions,

the

circuit

is

in-

active

(Q213

is

on

and

Q214

is

off).

When

the

heatsink

temperature

reaches

approxi-

mately

100°C,

the

resistance

of

RT201

de-

creases.

This

increases

the

base

voltage

applied

to

Q213,

turning

it

off.

Turning

off

Q213

allows

Q214

to

turn

on,

decreasing

the

voltage

at

Power

Adjust

potentiometer

R261.

This

reduces

the

base

voltage

to

Q215

which

causes

Q216

and

Q217

to

conduct

6

less,

~~ducing

the

collector

voltage

to

Q204

(Ampl-1).

This

reduces

the

transmitter

out-

put

power,

keeping

the

heatsink

at

a maximum

of

approximately

100°C.

When

the

heatsink

temperature

decreases

the

turns

TEST

PROCEDURES

These

Test

Procedures

arB

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

con-

trol

set

too

high.

Once

a

defect

is

pin-pointed,

refer

to

the

"Service

Check"

and

the

additional

corrective

measures

included

in

the

Transmitter

Troubleshooting

Procedure.

Before

starting

with

the

Transmitter

Test

Procedu

res

,

be

sure

the

transmitter

is

tuned

and

aligned

to

the

proper

operating

frequency.

Before

bench

testing

the

MASTR

II

Mobile

Radio,

be

sure

of

the

output

volta

ge

characteristics

of

your

bench

power

supply.

To

protect

the

transmitter

power

output

transistors

from

possible

instant

des-

truction,

the

f

ollowing

input

voltages

must

not

be

Transmitter

keyed

(50

resistive

load):

18

Volts

Transmitter

keyed

(no

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

~ccount.

The

volta

ge

limit

shown

for

a

non-optimum

load

is

for

"worst

conditions.

F

or

antenna

mismatches

likely

to

be

encountered

in

practi

ce,

the

actual

limit

will
