The

Model

R-600

is

a

It

covers

the

ception

of

SSB,

CW

and

.

The

heart

of

the

receiver

includes

a

highly

stabilized

VFO

and

PLL

synthesizer

for

trouble-free

reception.

.

The

circuits

include

band-pass

filters

interlocked

with

the

When

used

in

combination

with

a

transmitter,

the

MUTE

terminal

places

the

R-600

in

STAND-BY

mode.

.

The

RF

attenuator

provides

20 dB

attenuation,

making

it

possible

to

receive

strong

local

signals

without

dis-

tortion.

.

The

frequency

display

uses

easy-to-read

LED,

which

indicate

true

frequency

accurate

to

the

1kHz

order.

The

antenna

terminals

can

be

selected

according

to

the

signal

frequency

or

the

antenna

system

employed.

A

record

terminal

is

located

on

the

front

panel.

The

output

is

automatically

controlled

the

op-

timum

level

tion.

A

fuse

is

installed

in

the

antenna

to

prevent

CAUTION:

To

@

Multiband

Antenna

This

antenna

uses

more

than

one

doublet

for

multiband

re-

ception.

The

overall

length

“L”

is

the

same

as

that

of

the

If

the

lengths

L1,

L2

and

L3

are

cut

for

7

MHz,

14

MHz

and

28

MHz,

then

L1

is

tuned

to

(3x

will

cover

the

6~30

Antenna

Antennas

designed

operation

will

provide

Antennas

of

are

most

sui-

table

for

the

who

does

not

have

enough

of

@

Yagi

Antenna

The

Yagi

antenna

is

best

suited

for

reception

in

a

specific

band.

This

antenna

features

excellent

directivity;

it

provides

high

gain

and

minimizes

interference

when

properly

installed.

Yagi

antennas

commercially

available

are

designed

only

for

HAM

band

reception.

For

SW

reception,

it

will

be

necessary

for

you

to

construct

such

antennas

yourself.

(See

Fig.

1-6)

@

Grounding

Normally,

the

receiver

will

operate

without

being

grounded.

However,

a

good

earth

ground

improves

the

efficiency

of

an-

tennas

such

as

a

long-wire.

It

also

eliminates

inductive

noise

and

protects

the

operator

from

electric

shocks

through

the

AC

lines.

To

ground

the

receiver,

use

a

copper

or

brass

plate

(or

net

or

rod)

connected

to

a

copper

wire,

and

bury

it

in

the

ground

about

1~7

feet

(0.3~

2.0

m)

deep.

A

copper

water

pipe

(not

plastic)

may

also

be

used.

Never

use

a

gas

pipe

for

ground-

ing.

If

the

receiver

cannot

be

well

grounded

the

counterpoise

(antenna

radial)

would

be

acceptable.

1.5

SPEAKER

Audio

output

from

the

R-600

is

1.5

watts

into

8

ohms.

The

R-600

has

a

built-in

speaker.

However,

if

an

external

speaker

is

desired

(such

as

the

KENWOOD

SP-100),

simply

connect

it

to

the

EXT.SP

jack

on

the

rear

panel.

The

speaker

may

be

any

good

8

ohm

permanent

magnet

type,

4

inches

or

larger.

The

internal

speaker

is

disconnected

when

an

ex-

ternal

speaker

is

used.

`

1.6

HEAD

PHONES

Any

tow-Z

(4

headphones

may

be

used

with

the

R-600.

connect

the

headpnones

to

the

front-panel

phone

jack.

If

a

speaker

is

connected

to

the

receiver,

it

will

automatically

be

disconnected

when

the

headphones

are

plugged

into

the

jack.

1.7

CAUTION:

1.

Operation

of

this

may

result

in

Antenna

and

Grounding

Installation

of

antenna

and

grounding

is

important

for

opti-

mum

reception

of

short-wave,

broadcast

or

amateur

radio

signals.

A

good

outdoor

antenna

will

provide

the

best

results.

The

following

describes

various

antenna

types

and

their

in-

stallation.

NOTE:

A

simple

method

is

to

install

the

supplied

wire

antenna

as

high

as

possible,

it

must

be

extended

to

its

full

length

for

good

results.

€

Long

Antenna

This

is

the

simplest

antenna,

using

about

30

—

1000

feet

(10

~

30m)

of

wire

installed

between

poles,

trees

or

other

convenient

supports.

The

antenna

wire

should

be

heavy

8-gauge

vinyl

insulated,

stranded

wire

or

4-gauge

copper

wire

or

Copperweld.

This

type

of

antenna

must

be

installed

horizontally

to

a

length

of

60

feet

(20

m)

or

more,

and

be

po-

sitioned

as

high

as

possible,

Note

that

it

should

be

as

far

away

as

possible

from

AC

power

lines,

buildings,

trees

and

other

objects.

shows

an

types

such

as

3.2

MODE

SWITCH

When

receiving

strong

local

signals,

set

this

switch

to

AM

WIDE.

This

enhances

reception

with

little

interference,

providing

excellent

tone

are

present

near

the

received

quency,

set

the

switch

to

AM

NARROW.

This

narrows

the

bandwidth,

reducing

set

this

ENJOYING

SW

RECEPTION

Every

country

in

the

world

has

broadcast

stations,

and

most

countries

have

Amateur

radio

stations.

The

earth

is

virtually

surrounded

by

innumerable

radio

waves,

provid-

ing

us

with

information

and

news.

Your

R-600

intercepts

many

of

these

transmissions.

Radio

waves

cover

a

wide

range

of

frequencies

including

long-wave

(LF),

medium-wave

(MF),

and

short-wave

(SW)

or

high

frequency

(HF).

Since

short-wave

signals

travel

around

the

earth,

it

is

fun

receiving

exciting

news

and

exo-

tic

music

from

overseas

broadcast

stations

or

transmis-

sions

from

Amateur

radio

stations

and

various

industrial,

marine,

government,

and

military.

It

is

also

interesting

to

collect

reception

or

verification

(QSL)

cards.

To

ensure

maximum

enjoyment

of

short-wave

reception,

it

is

impor-

tant

to

know

the

features

of

short-wave

signals

-

how

the

signals

travel

around

the

earth,

the

method

of

receiving

signals

most

effectively,

the

method

of

identifying

the

country

broadcasting

programs,

etc.

Propagation

of

Radio

Waves

By

the

lonosphere

(See

Fig.

4-1)

The

earth

is

surrounded

by

the

atmosphere.

The

atmos-

pheric

molecules

existing

between

50

km

and

500

km

above

the

earth

collide

with

ultraviolet

rays

and

electrons

emitted

from

the

sun,

and

a

layer

of

electrons

and

ions

is

formed.

This

layer

is

called

the

ionosphere

and

it

has

a

characteristic

of

refracting

radio

waves.

Radio

waves

emitted

from

the

antenna

of

a

transmitter

can

be

classified

as

surface

waves

and

ionospheric

waves.

Surface

waves

travel

along

the

earth

directly,

and

are

used

mainly

for

me-

dium

frequency

AM

broadcast

and

TV

and

FM

broadcast.

lonospheric

(sky)

waves

travel

a

long

distance

because

they

are

refracted

repeatedly

between

the

ionized

layer

and

the

earth.

As

short-wave

broadcasts

propagate

by

ionospheric

waves,

their

signals

offen

reach

around

the

earth.

The

surface

wave

tends

to

weaken

at

HF

and

short-

wave

frequencies

and

therefore

travel

only

a

short

dis-

tance,

while

ionospheric

waves

persist

as

the

frequency

increases

(up

to

a

certain

point,

determined

by

ionization

intensity)

and

travel

long

distance

with

little

path

loss.

Ul-

tra

high

frequencies

pass

through

the

ionized

layer,

and

thus

the

service

area

is

limited

to

a

short

distance

from

the

antenna.

The

ionosphere

is

divided

into

three

layers,

DE

and

F,

as

shown

in

Fig.

4-1.

The

electron

density

in

the

layer

is

increased

in

steps

ac-

cording

to

the

distance

from

the

sun.

High

frequency

waves

are

refracted

by

the

F

layer

and

travel

a

long

dis-

tance.
