DESCRIPTION

The

FM

60A

is

a

rugged,

compact

commUnIca-

tions

unit

designed

to

operate

from

any

6

or

12

volt

d.c.

(negative

or

positive

ground)

vehicle

power

source

or

a

117

volt

a.c.

50

to

400

cycle

land

station

power

source.

The

FM

60A

is

designed

for

narrow-band

phase/

frequency

modulation

(±5KC

deviation)

opera-

tion

in

the

frequency

range

of

25

to

54

megacycles.

The

receiver

and

transmitter

sections

are

designed

for

single

channel,

crystal

controlled

operation.

The

transmitter

and

receiver

may

be

operated

on

the

same

channel

(simplex

frequency

assignment)

or

on

different

channels

(duplex

frequency

assign.

ment)

.

All

necessary

components

for

6

or

12

volt

d.c.

operation

of

either

polarity

or

117

volt

AC

opera-

tion

are

built

into

the

basic

communications

unit.

The

proper

circuitry

is

selected

by

the

wiring

of

the

external

power

plug

thereby

eliminating

the

need

for

jumpers

or

switches

in

the

basic

unit.

The

FM

60A

may

be

interchanged

in

any

6, 12

or

117

volt

system

without

modification

and

without

re-

gard

to

battery

polarity.

OPERATING INSTRUCTIONS

CONTROL FUNCTIONS:

There

are

only

three

external

controls.

The

left

knob

is a

conventional

volume

control;

the

right

knob

controls

the

squelch.

By

turning

the

squelch

knob

clockwise,

the

sensitivity

is

increased

and

as

this

control

is

advanced

clockwise,

a

point

will

be

reached

beyond

which

a

loud

hiss

will

be

heard.

However,

there

is a

setting

before

this

point

where

the

receiver

is

operating

at

optimum

sensitivity

in

a

squelched

(noiseless)

condition.

The

three-position

power

switch

on

the

panel

is

"OFF"

in

the

extreme

left

setting.

In

the

center,

or

"STDBY"

position,

the

receiver

only

is

operat.

ing,

and

the

transmitter

filaments

are

turned

off.

In

the

"OPERATE"

position,

the

receiver

remains

"ON"

however

the

transmitter

filaments

are

also

"ON."

After

a

warm-up

period

of

about

20

seconds,

the

transmitter

is

ready

for

operation

by

depressing

the

"push-to-talk"

switch

on

the

microphone.

The

"on-off"

pilot

lamp

located

to

the

left

side

of

the

power

switch

lights

when

the

set

is

turned

on.

The

pilot

lamp

on

the

right

side

lights

only

when

the

transmitter

is

on

the

air.

When

the

push-to-talk

microphone

switch

is de-

pressed,

the

transmitter

section

of

the

communica-

tion

unit

is

actuated,

the

red

transmit

lamp

lights

and

the

receiver

is

muted.

Release

of

the

push-to.

talk

switch,

turns

the

transmitter

section

off, ex-

tinguishes

the

red

transmit

lamp

and

actuates

the

receiver

section.

This

sequence

of

events

is

in

the

"OPERATE"

position

of

the

power

switch.

When

this

switch

is

in

the

"STDBY"

position

the

micro-

phone

push-to-talk

circuitry

is

inoperative.

3

l----------

The

use

of

the

"STDBY"

mode

of

operation

is

highly

recommended

where

long

periods

of

listen-

ing

only

is

expected

as

lower

power

drain

together

with

longer

transmitter

tube

life

will

result.

The

FM

60A

is a

highly

efficient

receiver-trans·

mitter

and

will

provide

reliable

communications

over

great

distances

if

properly

used.

Radio

operat.

ing

is

an

art

that

is

easily

learned

with

practice.

The

limitations

of

a

system

installation

in

any

particular

area

may

be

learned

through

use.

Every

system,

regardless

of

its

frequency

or

power,

will

have

some

locations

where

it

is

not

possible

to

communicate.

However,

within

its

range,

trees,

buildings,

small

hills

and

similar

obstructions

will

have

little

or

no

effect

on

communications.

The

range

of

a

system

is

dependent

on

a

few

important

factors,

such

as

location

and

height

of

base

station

antenna,

power,

and

nature

of

surrounding

terrain.

The

use

of

a

half-wave

rather

than

a

quarter-wave

base

station

antenna

is

highly

recommended

in

all

installations

for

best

possible

performance.

Assuming

that

the

most

efficient

installation

of

the

FM

60A

is

made,

one

important

consideration

remains.

This

is

correct

operating

procedure

and

a

few

important

notes

in

this

regard

are:

1.

Before

transmitting,

listen

to

the

receiver

and

make

certain

no

one

else

is

on

the

channel.

2.

Let

the

mobile

operator

get

in

the

practice

of

calling

the

base

station

for

instructions.

Since

the

base

station

is

in

a

known,

fixed

location,

the

mobile

operator

can

call

when

he

knows

he

is

in

a

good

location.

3.

Show

each

mobile

operator

how

radio

ac-

tually

helps

him

in

his

work

by

eliminating

doubts

about

delivery,

reducing

unnecessary

travel,

etc.

4.

If

you

are

trying

to

contact

a

mobile

unit

from

the

base

station,

remember

that

he

may

be

in

a

poor

radio-location,

he

mav

have

both

hands

busy

in

heavy

traffic,

or

he

ma-y

have

stopped

in

the

local

diner.

If

you

do

not

contact

him

after

one

or

two

quick

calls,

wait

a

few

minutes

before

calling

again.

5.

Keep

messages

short

and

brief.

Know

what

you

are

going

to

say

before

you

depress

the

micro-

phone

button.

Many

100

word

discussions

can

be

reduced

to

10

word

messages

by

thinking

and

planning

before

going

"on-the-air."

6.

Adopt

a

system

of

routine

and

preventative

maintenance

with

your

serviceman.

7.

Become

familiar

with

the

F.C.C.

rules

and

regulations

concerning

operation

of

two-way

radio

for

your

particular

class

of

service.

TRANSMlnER TUNE-UP

PROCEDURE:

CAUTION

The

plate

cap

of

the

type

6146

output

stage

is

"hot"

at

all

times

when

power

is

turned

ON.

This

applies

to

both

the

"STANDBY"

and

"ON"

positions

of

the

power

switch.

The

transmitter

duty

cycle

is

one

minute

on,

four

minutes

off;

therefore,

all

adjustments

should

be

made

as

quickly

as

possible,

keying

the

transmitter

only

when

ready

for

actual

adjustment

or

measure-

ment.

To

minimize

interference,

on-the-air

testing

(with

antenna

connected)

should

be

kept

to

a

minimum.

The

use

of

a 50

ohm

dummy

load

is

recommended

for

all

but

the

final

on-the-air

use

of

the

equipment.

If

extended

periods

of

testing

and/or

servicing

the

exciter

stages

of

the

transmitter

are

required

it

is

recommended

that

the

screen

of

the

6146

PA

stage

be

grounded.

All

tests

up

to

and

including

the

grid

of

the

final

The

value

of

meter

shunt

R149

is

such

that

the

micro-

ammeter

will

read

200

milliamperes

full

With

the

dummy

load

connected

to

the

output

terminal,

C153

should

be

slowly

exceeding

160

milliamperes

is

achieved.

Simultaneous

with

this

CABLE

INSTALLATION

Certain

precautions

must

he

observed

when

in-

stalling

the

FM

60A.

It

is

very

important

that

polarity

be

observed

on

vehicle

installations.

Using

the

power

cable

chart,

at

the

rear

of

the

manual,

first,

determine

which

cable

is

to

he

used.

In

most

installations,

you

will

find

that

modern

vehicles

employ

a 12

volt

negative

ground

system,

therefore,

be

sure

to

use

the

cable

required

for

12

volt

nega-

tive

ground

installations.

If

the

vehicle

is a

positive

ground

system

be

sure

to

usc

the

] 2

volt

positive

ground

cable,

etc.

Refer

to

rear

of

manual

for

cable

connections

for

front

mount

installations.

New

vehicles

will

generally

be

no

problem

so

far

as

polarity

is

concerned.

On

older

vehicles,

the

best

policy

is

to

use

a

volt

meter

and

check

the

battery

voltage

and

polarity

before

proceeding

with

the

installation.

Experience

will

generally

tell

you

what

the

voltage

and

polarity

of

the

various

make

and

type

vehicles

in

the

field

are.

It

is

extremely

important

that

polarity

and

volt-

age

be

observed

because

if

the

polarity

is

acciden-

tally

reversed,

you

will,

almost

without

exception,

burn

out

at

least

one

of

the

power

transistors.

TO

PREVENT

BURNING

OUT

POWER

TRANSIS-

TORS,

OBSERVE

VOLTAGE

AND

POLARITY.

Once

the

proper

cable

has

been

installed

in

a

vehicle,

the

FM

60A

receiver-transmitter

unit

may

be

exchanged

or

inter-changed

throughout

the

fleet

with

no

modification

or

switch

selection

required.

COMMUNICATIONS UNIT INSTALLATION

There

are

generally

three

or

four

different

ways

that

the

unit

may

be

mounted

in

the

cab

or

in

the

area

that

is

accessible

to

the

driver.

In

most

busi-

ness

and

industrial

applications,

it

will

be

found

that

it

is

most

desirable

to

locate

the

receiver-

transmitter

somewhere

in

the

cab

of

the

truck

or

the

front

seat

area

of

the

vehicle.

This

has

the

advantage

of

short

battery

cables

with

less

voltage

drop

and

less

chance

of

abrasion

and

wear.

FLOOR

MOUNT:

Using

the

FM

60A

receiver-transmitter

as a

pat-

tern,

place

it

on

the

floor

of

the

vehicle

and

various

locations

until

the

most

convenient

location

is

found.

The

best

location

will

be

one

where

the

driver

can

tell

at

a

glance

whether

his

set

is

on

or

off

and

where

he

can

reach

the

controls

on

the

front

panel.

When

setting

up

this

location,

be

sure

to

give

consideration

to

the

length

of

the

battery

cable.

After

the

location

is

found,

secure

the

uni·

PL26610·Gl.

When

drilling

through

the

floor

of

a

vehicle,

or

through

any

other

panel

or

part

of

it,

use

every

precaution

to

avoid

drilling

through

a

gas

line

or

electrical

wiring,

etc.

Wherever

it

is

not

possible

to

use

nuts

and

bolts,

drill

with

a

proper

size

drill

for

self

tapping

screws

and,

using

a

good

long

screw

driver,

drive

the

steel

screws

firmly

into

place.

Always

fasten

parts

securely

to

the

vehicle

to

avoid

noise

from

"shaky"

installation.

UNDER-DASH

MOUNT:

Using

the

radio

as

a

template,

find

the

best

loca·

tion

under

the

dash

of

the

vehicle.

Take

into

con·

sideration,

special

handles

found

on

dump

trucks

and

controls

found

on

various

types

of

vehicles

in

the

field.

After

a

practical

location

is

found,

secure

the

universal

mounting

bracket

in

place

with

the

proper

hardware.

Use

every

precaution

to

make

the

battery

cable

as'

short

as

possible

and

route

it

in

such

a

way

that

it

will

not

interfere

with

the

various

controls

under

the

dash.

Wherever

the

cable

goes

through

the

chassis,

use

a

heavy

rubber

grommet

to

prevent

chafing

and

eventual

short

circuit.

Extra

precautions

seldom

take

more

time

when

the

in·

stallation

is

being

made,

but

can

save

many

hours

of

future

maintenance

and

possibly

a

dangerous

situation

for

the

driver.

REMOTE INSTALLA

liONS:

Whenever

it

is

not

practical

or

desirable

to

have

the

radio

unit

mounted

in

view

of

the

driver,

it

should

be

mounted

remotely.

In

a

passenger

car

the

most

practical

place

is

usually

in

the

trunk;

however,

there

are

certain

vehicles

that

adapt

them·

selves

to

other

locations.

Always,

bear

in

mind

that

the

battery

cable

should

be

as

short

as

possible

and

use

the

same

precautions

discussed

for

the

floor

mount.

Place

the

unit

in

such

a

way

that

it

will

not

interfere

with

loading

and

unloading

of

the

trunk

and

find

the

shortest

route

from

the

unit

to

the

battery,

running

the

cahle

along

this

route.

Avoid

sharp

metal,

protrusions,

and

use

every

means

to

protect

the

cable

from

abrasion.

Whenever

it

is

necessary

to

run

the

battery

cable

on

the

outside

of

the

vehicle

under

the

floor,

stay

clear

of

areas

that

get

extremely

hot,

such

as

the

exhaust

pipe

or

the

muffler.

The

cable

connecting

the

unit

to

the

remote

head,

should

be

run

on

the

inside

of

the

vehicle

unless

it

is

possible

to

employ

BATTERY

CABLE

INSTALLATION:

The

battery

cable

should

be

run

from

the

unit

to

the

battery

in

as

short

a

line

as

possible.

Some·

where

near

the

battery,

mount

the

and

fuse

with

the

two

sheet

metal

screws

furnished.

Terminate

the

"hot"

lead

at

the

fuse

holder,

cutting

off

any

extra

cable.

Using

this

extra

cable,

run

a

lead

from

the

other

side

of

the

fuse

holder

to

the

"hot"

side

of

the

battery.

Terminate

this

"hot"

lead

at

the

battery

terminal,

or

on

the

starter

post.

Never

connect

to

a

voltage

point

on

the

vehicle

that

has

wire

smaller

than

the

starter

cable.

Do

not

substi·

tute

a

wire

that

is

of

smaller

diameter

than

that

furnished

with

the

installation

kit.

The

ground

lead

in

the

trunk

mount

installations

should

be

securely

bonded

in

the

immediate

vicinity

of

the

unit.

Do

not

ground

to

upper

braces

and

lor

It

is

preferable

to

attach

the

ground

lead

to

the

floor

of

the

trunk

and

solder

same

if

at

all

possible.

This

will

require

an

un·

usually

large

iron

(500

watts

preferably)

and

a

good

mechanical,

as

well

as

electrical

connection

is a

must.

In

front

mount

installations

the

ground

lead

(black)

should

be

securely

fastened

to

the

battery

terminal

or

to

the

engine

block.

ANTENNA

INSTALLATION:

General

installation

instructions

are

furnished

with

the

various

antenna

kits.

However,

there

are

certain

precautions

that

must

be

observed

when

installing

any

antenna.

The

most

frequently

used

antenna

will

be

the

quarter

wave

whip.

Although

the

ideal

location

for

this

antenna

is

the

center

of

the

roof

of

the

rarely

will

it

be

possible

to

ROUTING

OF

ANTENNA

TRANSMISSION

LINE:

Always

route

the

transmission

line

through

the

area

which

provides

maximum

clearance.

AVOID

SHARP

BENDS.

As

the

be

sure

to

place

it

in

such

a

way

that

it

will

not

be

squeezed

when

etc.,

are

put

back

in

place.

After

replacing

all

should

be

checked

for

continuity

between

the
