INSTALLATION

The

transceiver

is

designed

to

provide

a

complete

single

unit

installation

for

fixed,

portable,

or

mobile

operation.

Two

prewired

plugs

are

furnished

with

the

unit

for

AC

or

DC

operation.

This

system

provides

the

flexibility

required

for

various

installa-

tions

and

allows

rapid

change

from

fixed

to

mobile

operation.

Base

Station

Installation

;

The

transceiver

is

designed

for

use

in

many

areas

of

the

world

using

supply

voltages

that

may

differ

from

the

operators

local

supply

voltage.

Therefore,

before

connecting

the

AC

cord

to

the

power

outlet,

be

sure

that

the

voltage

marked

on

the

rear

of

the

transceiver

agrees

with

the

local

AC

supply

voltage.

CAUTION

Permanent

damage

will

result

if

improper

AC

supply

voltage

is

applied

to

the

trans-

ceiver.

The

transceiver

should

be

connected

to

a

good

ground.

The

ground

lead

should

be

connected

to

the

terminal

marked

GND

located

on

the

rear

panel

of

the

trans-

ceiver.

Mobile

Installation

;

The

transceiver

will

operate

satisfactorily

from

any

12

volt

negative-ground

battery

source

by

connecting

the

DC

power

cord

to

the

rear

panel

receptacle.

For

under-dash

mounting,

a

special

mounting

bracket

is

available

from

your

dealer.

A

location

should

be

selected

clear

of

heater

ducts.

No

special

mounting

pre-

cautions

need

be

observed

if

adequate

ventilation

space

is

available.

A

minimum

of

two

inches

of

air

space

above

the

cabinet

top

and

on

all

sides

is

recommended

to

allow

proper

air

flow

around

the

cabinet.

Never

stack

other

units

above

or

below

the

cabinet

since

the

accumulated

heat

from

both

units

could

cause

perma-

nent

damage.

The

transceiver

requires

an

average

of

14

amps

on

transmit

and

20

amps

on

voice

peaks.

The

fuse

in

the

DC

power

cable

should

be

rated

at

20

amps.

When

making

connections

to

the

car

battery,

be

certain

that

the

RED

lead

is

connected

to

the

positive

(+)

terminal

and

the

BLACK

lead

to

the

negative

(—)

terminal

of

the

battery.

Reversed

connections

could

permanently

damage

the

transceiver.

The

BLACK

lead

should

run

directly

to

the

negative

terminal

of

the

battery.

Using

the

car

frame

as

a

negative

connection

or

connecting

the

positive

lead

at

a

point

such

as

the

ignition

switch

places

the

devices

creating

noise

in

the

same

current

path

as

the

transceiver

and

fails

to

take

advantage

of

the

filtering

action

of

the

battery.

The

power

cable

should

be

kept

away

from

ignition

wires

and

be

as

short

as

possible

to

minimize

voltage

drop

and

to

provide

a

low

impedance

path

from

the

transceiver

to

the

battery.

Prior

to

operating

the

transceiver

in

a

mobile

installa-

tion,

the

voltage

regulator

setting

should

be

checked.

In

many

vehicles,

the

voltage

regulations

is

very

poor

and

in

some

cases,

the

regulator

may

be

adjusted

for

an

excessively

high

charging

voltage.

As

the

battery

and

regulator

age.

the

maximum

voltage

while

charg-

ing

can

increase

to

a

very

high

level

which

is

in-

jurious

to

the

battery

and

could

cause

damage

to

the

transceiver.

The

transceiver

is

designed

to

operate

from

a

source

voltage

range

of

11

to

14

-volts.

It

is

necessary

to

carefully

set

the

regulator

so

that

the

highest

charg-

ing

voltage

does

not

exceed

14

volts.

The

transceiver

should

be

switched

“OFF”

when

vehicle

is.

started

to

prevent

voltage

transcients

from

damaging

power

supply

transistors.

Antenna

;

CAUTION

Never

transmit

without

having

proper

antenna

or

dummy

load

connected

to

the

transceiver

The

transceiver

is

designed

for

use

with

resonant

anten-

na

having

an

impedance

50-75

ohm

resistive

load.

The

antenna

is

usually

the

most

critical

part

of

a

station

installation.

Results

both

in

receiving

and

trans-

mitting

will

depend

on

how

well

the

antenna

is

installed

and

adjusted.

Any

of

the

common

antenna

systems

designed

for

use

on

the

high

frequency

amateur

bands

may

be

used

with

the

transceiver,

provided

the

input

impedance

of

the

antenna

system

is

within

the

capa-

bility

of

the

transceiver

pi-matching

network

(50-75

ohms).

es

ee

If

a

tuned

open

wire

transmission

line,

or

a

long

wire

antenna

is

used,

a

suitable

antenna

tuner

must

be

used

between

the

antenna

and

the

transceiver

to

provide

an

impedance

match

between

the

unbalanced

coaxial

out-

put

of

the

transceiver

and

the

balanced

open-wire

feeder

or

Jong

wire.

For

mobile

operation,

most

of

the

antennas

on

the

market

will

results

with

securely

grounded

to

the

CLARIFIER

;

The

clarifier

control

provides

a

means

for

tuning

the

receiver

trequency

3

KHz

to

either

side

of

the

transmitting

trequency.

Thus,

it

is

possible

to

set

the

pitch

of

the

voice

you

are

receiving

to

the

opera-

SSE

most

readable

point

without

affecting

your

trans-

mitting

frequency.

Its

use

is

particularly

valuable

in

“net”?

operation

where

several

participants

may

be

transmitting

slightly

off

frequency.

The

clari-

With

the

clarifier

switch

out

position,

the

red

lamp

turns

off

and

the

receiver

is

locked

to

the

transmitting

frequency.

Normally,

you

will

want

to

keep

the

clarifier

in

the

OFF

position

until

the

initial

contact

is

made.

The

OPERATION

The

tuning

procedure

of

the

transceiver

is

not

complicated,

however,

care

should

be

exercised

when

tuning

to

insure

peak

performance

of

the

equip-

ment.

The

following

paragraphs

describe

the

procedure

for

receiver

and

transmitter

tuning.

INITIAL

CHECK

Before

connecting

the

transceiver

to

a

power

source,

carefully

examine

the

unit

for

any

visible

damage.

Check

that

all

modules

and

crystals

are

firmly

in

place

and

that

controls

and

switches

are

operating

normally.

En-

sure

that

voltage

specification

marked

on

rear

panel

matches

the

supply

voltage.

FREQUENCY

SELECTION

The

main

tuning

dial

is

color

coded

with

the

band

selector

switch

for

proper

frequency

read

out.

When

band

selected

is

marked

in

Red,

the

operator

reads

the

Red

numbers

on

the

main

tuning

dial.

When

for

example

the

band

selected

is

marked

in

White

on

trans-

ceiver

front

panel,

the

operator

reads

the

Black

numbers

on

main

tuning

dial.

The

main

tuning

dial

is

marked

in

25

KHz

increments

between

each

100

KHz

segment.

This

provides

a

course

frequency

setting

within

the

band.

The

dial

skirt

surrounding

the

tuning

knob

is

marked

in

1

KHz

in-

crements

and

provides

for

fine

settings

of

the

trans-

ceiver

operating

frequency.

Following

the

example

shown,

familiarize

yourself

with

the

relationship

of

main

and

skirt

dial

frequency

read-

out.

To

set

the

control

to

the

100

KHz

point

on

the

dial

nearest

the

desired

frequency.

Tune

the

deflection.

Tune

the

transceiyer

to

the

100

signal

for

Two

signals

may

be

heard

near

the

100

KHz

point.

One

of

these

is

a

signal

feeding

through

the

IF

stages.

Always

calibrate

to

the

stronger

of

these

two

signals.

To

calibrate,

hold

tuning

knob

firmly

at

zero

beat

point

and

rotate

skirt

vernier

dial

to

zero

position.

The

skirt

vernier

dial

surrounds

the

tuning

knob

and

is

held

in

position

by

a

friction

locking

device.

This

dial

is

easily

movable

by

hand

but

will

retain

its

position

after

calibration.

The

trans-

ceiver

must

be

calibrated

when

changing

mode

of

opera-

tion

of

LSB,

USB,

AM

or

CW,

Switch

the

calibrator

to

the

25

KHz

position

and

note

that

the

calibrator

signal

can

be

heard

at

every

25

KHz

point.

The

calibrator

switch

should

be

in

the

OFF

position

in

normal

use

of

the

transceiver.
