OPERATING

MANUAL

The

Kenwood

TS-511S

is

a

powerful,

five

band

transceiver

for

operation

on

SSB

and

CW.

It

features

built-in

VOX,

crystal

calibrator,

noise

blanker,

incremental

tuning

and

1

kHz

frequency

readout.

High

stability

is

obtained

by

the

use

of

a

well

designed

heterodyne

VFO.

LOCATION

Select

a

proper

operating

location.

It

should

be

dry

and

free

from

direct

sunlight.

There

should

be

at

least

3

inches

clearance

between

any

objects

and

the

rear

of

the

trans-

ceiver

to

allow

adequate

air

CAUTION:

Before

make

sure

the

is

set

to

POWER

and

that

the

stand-by

Connect

a

suitable

antenna

to

the

ANT

jack

on

the

transceiver

(See

Fig.

An

antenna

is

considered

suitable

when

it

presents

a

50

~

75

load

to

the

transceiver,

The

performance

directly

the

type

of

antenna

that

is

chosen.

For

3.8

OPERATION

WITH

A

LINEAR

AMPLIFIER

The

TS-511S

transceiver

is

readily

compatible

with

most

linear

amplifiers.

It

has

extra

relay

contacts

for

amplifiers

which

require

external

switching

control.

These

accessory

contacts

are

accessible

through

the

REMOTE

socket

on

the

rear

panel.

The

following

relay

contacts

may

be

used

in

accord

with

the

individual

requirements

of

the

chosen

amplifier.

NOTE:

Since

most

linear

amplifiers

normally

require

about

100

watts

of

drive

for

CW

operation,

the

output

of

the

TS-511S

may

be

reduced

accordingly

by

the

following

steps.

Follow

the

procedures

for

CW

operation

using

a

dummy

load.

When

the

transceiver

is

tuned,

the

output

may

be

reduced

by

slowly

turning

the

DRIVE

knob

in a

counterclockwise

direction

until

the

correct

amount

of

drive

is

obtained.

Normally

the

DRIVE

knob

will

have

to

be

moved

only

17

or

2

increments

on

the

DRIVE

scale

to

reduce

the

output

by

100

to

200

watts.

When

SSB

operation

is

desired,

the

DRIVE

knob

must

be

returned

to

its

original

position

for

maximum

drive.

REMOTE

5

is

normally

open

in

respect

to

ground.

In

the

receive

condition

the

relay

contacts

are

open.

In

the

transmit

state

the

relay

contacts

are

closed

and

shorted

to

ground.

4

is

connected

to

ground.

3

is

normally

closed

in

respect

to

ground.

In

the

receive

condition

the

relay

contacts

are

closed.

In

the

transmit

state

the

relay

contacts

are

open.

NOTE:

The

use

of

LSB

or

USB

is

dependent

upon

the

chosen

band.

The

following

combinations

are

customary:

3.5~

4.0
