INSTRUCTIONS

RECEIVER

LOCATION

The

receiver

may

be

placed

anywhere

in

the

room,

but

for

greatest

satisfaction

it

should

be

located:

l.

Away

from

any

bright

light

that

may

fall

directly

on

the

screen

or

be

reflected

from

it;

this

includes

win-

dows

and

lamps.

Some

illumination

in

the

room,

off

to

one

side,

is

desirable,

however,

to

prevent

eye-

strain.

l.

To

provide

comfortable

viewing

and

ease

of

opera-

tion.

3.

At

lease

one

-inch

away

from

a

wall

to

allow

for

cab-

inet

ventilation.

This

is

very

important.

ANTENNAS

The

choice

of

a

television

antenna

depends

entirely

on

the

location

of

the

receiver

with

respect

to

all

television

station

transmitting

antennas

in

the

area.

Maximum

pick-

up

is

obtained

when

the

receiving

antenna

is

directly

in

line

of

sight

with

the

transmitting

antenna.

"Bilt-In-Tenna."

All

receivers

using

the

TS-ll4

series

television

chassis

are

equipped

with

the

Motorola

"Bilt-In-

Tenna",

mounted

inside

the

cabinet,

for

use

in

good

signal

areas.

When

this

antenna

is

used,

the

following

precautions

should

be

observed

for

best

reception:

l.

In

order

to

get

maximum

performance

and

satisfac-

tory

pictures

from

the

"Bilt-In-Tenna",

ample

sig-

nals

from

the

television

station

must

be

present

at

the

location

of

the

receiver.

Normally,

the

strength

of

the

signals

will

vary

throughout

the

room

in

which

the

receiver

is

located.

For

this

reason,

better

pic-

tures

will

be

obtained

if

the

receiver

is

tried

in

all

possible

locations

in

the

viewing

room

and

is

then

placed

where

the

clearest

pictures

are

received

from

all

stations.

Avoid

large

metallic

objects,

such

as

radiators,

metal

panels,

etc.

l.

Lamps,

vases

and

metallic

objects,

when

placed

on

top

of

the

receiver,

may

affect

the

~fficiency

of

the

"Bilt-In-Tenna".

Indoor

Antenna.

If

additional

pick-up

is

necessary

an

indoor

antenna,

placed

on

or

near

the

receiver,

maybe

used.

The

antenna

should

be

rotated

and

the

arms

should

be

ad-

justed

for

the

best

signal,

with

no

ghosts

or

reflections.

Normally,

the

arms

should

be

extended

on

the

low

channels

(Z-6)

and

telescoped

on

the

high

channels

(7-13).

Outdoor

Antenna.

The

Motorola

"Bilt-In-Tenna"

or

the

indoor

type

antenna

will

give

satisfactory

reception

in

strong

signal

areas;

but,

if

the

receiver

is

located

in

a

fringe

or

weak

signal

area,

an

outdoor

antenna

is

recommended.

In

areas

free

of

obstructions

and

reflections,

within

rea-

sonable

proximity

to

television

transmitters,

a

dipole

and

reflector

will

prove

satisfactory.

Since

such

an

antenna

has

a

relatively

small

band

coverage,

a

special

antenna

covering

all

twelve

television

channels

should

be

used

if

it

is

desired

to

receive

stations

on

channels

of

widely

separated

frequen-

cies.

I-:ocation

of

the

antenna

should

be

decided

from

the

stand-

point

of

maximum

signal

pick-up.

ln

general,

the

antenna

should

be

broadside

to

the

tFansmitting

antenna

and

should

be

as

high

as

pas

sible.

If

a

reflector

is

used,

the

antenna

should

be

oriented

so

that

the

driven

element

is

closest

to

the

station

and

the

reflector

farthest

away.

Locating

the

antenna

and

lead-in

as

far

away

as

possible

from

highways,

hospitals,

doctors'

offices,

electrical

ma-

chinery,

etc.,

will

help

to

reduce

noise

pick-up

from

such

sources.

Also,

it

is

desirable

to

keep

the

antenna

at

least

six

feet

away

from

other

antennas,

metal

roofs,

gutters,

or

other

metal

objects

to

prevent

unwanted

reflections

and

shielding.

Lead-In.

Since

the

TS-ll4

chassis

i~

designed

for

300

ohm

input,

the

standard

300

ohm

twin

lead

line

should

be

used

for

connecting

the

outside

antenna

to

the

receiver.

Twisting

the

line

one

complete

turn

per

foot

of

running

iength

helps

to

reduce

noise

pick-up

on

the

line.

The

lea.d-in

should

be

supported

on

stand-off

insulators

and

kept

tight

enough

to

prevent

mechanical

damage

through

swaying.

Avoid

running

the

lead-in

close

to

metal

gutters,

iron

standpipes,

etc.

In

areas

of

very

strong

signals,

or

where

severe

local

electrical

interference

is

encountered,

300

ohm

shielded

twin

lead

is

recommended.

The

shield

braid

should

be

grounded.

An

approved

lightning

arrestor

should

be

used.

RECEIVER

ANTF:NNA

CONNECTION

The

antenna

lead-in

to

the

receiver

is

connected

to

the

two

screws

of

the

terminal

strip

on

the

rear

of

the

cabinet.

Disconnect

the

"Bilt-In-Tenna"

leads

from

the

terminal

strip

before

attaching

an

external

antenna

lead-in.

Some-

times,

reversing

the

lead-in

connections

at

the

receiver

may

improve

picture

quality

and

overall

performance.

NOTE:

In

but

when

the

adjustments

should

be

made

The

important

point

to

in

mind

is

to

obtain

a

with

as

much

Constant

use

CHECK

After

should

be

made.

This

is

done

by

and

observing

the

output

on

the

oscilloscope,

as

taken

between

the

picture

The

across

the

antenna

ter-

mi-;,als

on

the

chassis

with

the

antenna

lead-in

re•

moved.

The

should

be

as

short

as

possible.

3.

Connect

the

oscilloscope

through

a

decoupling

resis-

tor

of

150,

000

ohms,

between

the

(12AT7)

and

chassis.

4.

Short

out

the

to

chassis.

5.

Refer

to

Figure

for

the

locations

of

the

antenna

and

RF

listed

previously

gives

the

channel

and

alignment

frequencies.

6.

The

antenna

coils

are

tuned

to

the

video

carrier

fre-

quency

and

the

RF

are

tuned

to

the

sound

Check

channels

7

to

13

for

proper

and,

if

necessary,

tune

the

coil

L-6.

These

coils

may

be

tuned

by

spreading

them

to

decrease

inductance

or

compressing

them

to

increase

their

inductance.

See

Figure

9

for

location

of

coils.

This

will

have

more

effect

on

channels

10

to

13

than

7

to

9.

If

L-6

is

ad-

justed,

it

may

be

necessary

to

readjust

RF

trimmer

C-6,

and

recheck

the

high

channels.

NOTE:

As

the

bandwidth

of

the

high

channels

is

very

broad,

a

slight

variation

is

permissible.

NOTE:

Each

by

noting

whether

can

drop

If

requirement,

a

compromise

must

be

made

by

re-

setting

channel

whichever

is

closer

to

the

in

question.

Example:

and

tune

This

will

tend

to

move

channel

sound

mark-

er

out

of

the

trap

but

this

can

be

com-

Do

not

adjust

any

more

than

OVERALL

RECEIVER

SENSITIVITY

MEASUREMENT

An

overall

measurement

of

sensitivity

is

made

as

fol-

lows:

1.

Connect

an

AM

signal

generator

to

the

input

termi-

nals

of

the

receiver

chassis

after

removing

the

short

300

ohm

lead

which

connects

to

the

antenna

input

strip

on

the

back

of

the

cabinet.

To

match

the

gen-

erator

to

the

receiver

input,

a

resistor

matching

net-

work

should

be

used.

In

the

case

of

a

generator

with

a

50

ohm

output

impedance,

for

example,

place

a

100

ohm

resist<>r

in

series

with

the

output

terminal

of

the

generator

and

a

150

ohm

resistor

in

series

with

the

ground

terminal,

2.

From

tube

to

chassis,

connect

a

calibrated

oscilloscope,

NOTE:

To

calibrate

scope,

connect

it

across

6,

3

volt

filament

supply.

The

peak-to-peak

amplitude

on

the

screen

will

then

be

approximately

18V

(

to

the

video

carrier

frequency

of

the

channel

being

checked.

Generator

signal

should

be

30%

The

signal

from

the

should

be

less

than
