The

Model

R-600

is

a

professional

class

general

co-

verage

receiver

for

broadcast

and

shortwave

listening.

It

covers

the

150

kHz

through

30

MHz

bands

for

re-

ception

of

SSB,

CW

and

AM.

.

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

band

selector

switch

for

eade

of

tuning.

.

The

ceramic

filter

circuit

is

also

interlocked

terminal

places

the

R-600

in

.

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

order.

The

antenna

terminals

can

be

selected

according

to

the

signal

frequency

or

system

employed.

A

is

located

on

panel.

The

output

level

is

automatically

controlled

to

the

op-

timum

level

independent

of

the

tion.

A

fuse

is

installed

in

the

antenna

circuit

to

prevent

extremes

of

heat

and

humidity.

Choose

an

and

avoid

operat-

ing

ANTENNA

@

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

Wire

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.

Fig.

1-1

shows

an

inverted

L

antenna.

Other

antenna

types

such

as

sloping,

vertical,

etc.

are

also

possible.

A

long-wire

antenna,

when

installed

in

an

open

area,

is

suitable

for

all-band

operation.

(See

Fig.

1-1).

@

Doublet

This

type

of

antenna

is

suitable

for

reception

of

a

when

the

is

at

a

right-angle

(broadside)

to

the

de-

sired

signal

and

the

frequency

for

which

the

antenna

is

cut.

It

must

be

used

with

a

75-ohm

coaxial

feeder.

(See

@

Inverted

Antenna

This

is

a

modified

antenna

designed

to

be

installed

on

a

single

pole

support.

The

characteristics

of

this

anten-

na

are

almost

the

same

as

those

of

a

doublet.

The

overall

length

@

Multiband

Antenna

This

antenna

uses

more

than

one

doublet

for

multiband

re-

ception.

The

overall

length

“L”

is

the

same

as

that

of

the

doublet.

If

the

lengths

L1,

L2

and

L3

are

cut

for

7

MHz,

14

MHz

and

28

MHz,

then

L1

is

tuned

to

21

MHz

(3

x

7

MHz),

permitting

reception

on

4

amateur

bands

7

~

28

MHz.

When

used

only

for

reception,

this

antenna

will

cover

the

6~

30

MHz

SW

bands.

(See

Fig.

1-4)

Antenna

Antennas

designed

Antennas

designed

for

band

(3.5

or

7

~

operation

will

pro-

vide

satisfactory

broadcast

reception

for

SW

stations

near

the

HAM

bands.

Antennas

of

this

type

are

most

suitable

for

the

listener

who

does

not

have

enough

space

for

instal-

lation

of

a

doublet

or

long-wire

antenna.

(See

Fig.

1-5)

@

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.

However,

if
