GENERAL

DESCRIPTION

The

circuit

used

in

this

6

band

portable

radio

incorporates

17

transistors

13

diodes

and

2

thermistors.

A

ferrite

bar

antenna

feeds

the

AM

broadcasting

signal

to

the

AM

mixer

and

a

telescopic

rod

antenna

feeds

the

AM

broadcasting

signal

to

the

AM

mixer,

2

IF

amplifiers

and

a

diode

detector.

A

telescopic

rod

antenna

feeds

the

FM

broadcasting

signal

to

the

FM

RF

amplifier,

FM

mixer,

3

IF

amplifier

and

FM

detector

(2

diodes).

The

audio

signal

passes

through

a

5

transistor

audio

amplifier

circuit.

An

AM

AVC

voltage

is

fed

back

to

the

1st

IF

amplifier.

An

FM

AVC

voltage

is

fed

back

to

the

FM

RF

amplifier.

An

AFC

voltage

is

fed

back

to

the

FM

converter.

at

any

time

to

check

the

alignment

of

proceed

as

follows;

1)

Connect

an

enough

to

swing

the

most

sensitive

range

of

the

output

meter.

4)

Use

a

non-metallic
