When

Not

Purchased

Directly

From

MFJ

Enterprises,

Inc.:

Before

continuing

any

further

with

your

MFJ

kit

check

with

your

Dealer

about

their

return

policy.

If

your

Dealer

allows

returns,

your

kit

must

be

returned

before

you

begin

construction.

Return

Policy

on

Kits

When

Purchased

Directly

From

MFJ

Enterprises,

Inc.:

Your

MFJ

kit

may

be

returned

to

the

factory

in

its

pre-assembled

condition

only.

The

reason

for

this

stipulation

is,

once

you

begin

installing

and

soldering

parts,

you

essentially

take

over

the

role

of

the

device's

manufacturer.

From

this

point

on,

neither

MFJ

nor

its

dealers

can

reasonably

held

accountable

for

the

quality

or

the

outcome

of

your

work.

Because

of

this,

MFJ

cannot

accept

return

of

any

kit-in-progress

or

completed

work

as

a

warranty

item

for

any

reason

whatsoever.

If

you

are

a

new

or

inexperienced

kit

builder,

we

urge

you

to

read

the

manual

carefully

and

determine

whether

or

not

you're

ready

to

take

on

the

job.

If

you

wish

to

change

your

mind

and

return

your

kit,

you

may--but

you

must

do

it

before

you

begin

construction,

and

within

ten

(10)

working

days

of

the

time

it

arrives.

MF

J

Enterprises,

Inc.

Warrants:

Your

kit

contains

each

item

specified

in

the

parts

list.

Missing

Parts:

If

you

determine,

during

your

pre-construction

inventory,

that

any

part

is

missing,

please

contact

MFJ

and

we'll

send

the

missing

item

to

you

free

of

charge.

However,

before

you

contact

MFI,

please

look

carefully

to

confirm

you

haven't

misread

the

marking

on

one

of

the

other

items

provided

with

the

kit.

Also,

make

certain

an

alternative

part

hasn't

been

substituted

for

the

item

you're

missing.

Ifa

specific

part

is

no

longer

available,

or

if

Engineering

has

determined

that

an

alternative

component

is

more

suitable,

MFJ

reserves

the

right

to

make

substitutions

at

any

time.

In

most

cases,

these

changes

will

be

clearly

noted

in

an

addendum

to

the

manual.

Defective

Parts:

Today's

electronic

parts

are

physically

and

electrically

resilient,

and

defective

components

are

rare.

However,

if

you

discover

an

item

during

your

pre-construction

inventory

that's

obviously

broken

or

unserviceable,

we'll

replace

it.

Just

return

the

part

to

MFJ

at

the

address

below

accompanied

with

an

explanation.

Upon

receipt,

we'll

test

it.

If

it's

defective

and

appears

unused,

we'll

ship

you

a

new

one

right

away

at

no

charge.

Missing

or

Defective

Parts

After

You

Begin

Assembly:

Parts

and

materials

lost

or

damaged

after

construction

begins

are

not

covered

under

the

terms

of

this

warranty.

However,

most

parts

supplied

with

MFJ

kits

are

relatively

inexpensive

and

MFJ

can

replace

them

for

a

reasonable

charge.

Simply

contact

the

factory

with

a

complete

description.

We'll

process

your

order

quickly

and

get

you

back

on

track.

Factory

Repair

After

You

Begin

Assembly:

Kits-in

progress

and

completed

kits

are

specifically

excluded

from

service,

your

kit

must

be

fully

completed,

unmodified,

and

the

assembled

using

rosin-core

solder.

In

the

event

your

repair

will

require

more

than

an

(or

$36.00,

subject

to

change),

our

Transceiver

Construction

Manual

INTRODUCTION

This

manual

contains

the

information

you

need

to

build

your

kit.

The

cub

is

unique

because

it

uses

both

surface-mount

(SMD)

and

conventional

electronic

components.

From

an

electrical

standpoint,

surface-mount

circuitry

has

many

advantages.

However,

SMD

parts

are

too

tiny

for

most

people

to

handle

in

a

kit.

MFJ

solves

this

problem

by

pre-installing

many

of

the

kit's

parts

using

our

automated

SMD

assembly

equipment.

These

machines

accomplish--in

a

matter

of

minutes--what

would

take

a

trained

assembler

an

entire

day

to

complete

by

hand.

Then,

once

the

SMD

work

is

complete,

we

hand

the

project

over

to

you.

You'll

begin

by

inventorying

the

parts

packages

to

ensure

everything

you

need

is

included.

Parts

are

grouped

into

two

categories.

Some

are

generic

components

such

as

switches,

jacks,

controls,

trimmers,

and

the

PA

transistor.

The

rest

are

frequency-determining

coils,

capacitors,

and

crystals

that

determine

the

band

of

operation.

To

complete

your

cub,

you'll

need

only

conventional

bench

tools

and

general

knowledge

of

through-hole

pc-

construction

methods.

To

help

you

along,

this

manual

provides

step-by-step

—

guidance

for

each

operation.

When

construction

is

complete,

it

walks

you

inspection,

testing,

and

tuning.

Finally,

it

shows

you

how

to

install

the

case

and

add

the

finishing

touches.

In

a

few

short

hours,

you'll

be

taking

to

the

airwaves

with

your

new

radio.

BEFORE

YOU

START

BUILDING

Work

Area:

You'll

need

a

clean,

smooth,

and

well-lighted

area--a

place

where

you

can

handle

small

parts

without

losing

them.

A

sheet

of

white

poster

board

makes

a

good

construction

surface.

Well-diffused

overhead

lighting

and

a

supplemental

high-intensity

desk

lamp

provide

strong

lighting

for

close-up

work.

Be

sure

to

keep

the

work

area

free

of

clutter

and

discarded

wire

ends.

Tools

and

Supplies:

Here's

a

checklist

of

the

tools

and

supplies

you'll

need:

O

Low-wattage

Avoiding

Errors:

Experience

shows

there

are

four

common

mistakes

builders

make.

Avoid

these,

and

your

kit

should

work

on

the

first

try!

1.

Installing

Wrong

Part:

Pre-sort

components

before

you

begin

and

double-

check

the

numbers

stamped

on

each

part

before

installing.

2.

Reversing

Polarized

or

Keyed

Parts:

ICs,

transistors,

diodes,

and

electrolytic

capacitors

must

be

installed

only

one

way.

Always

double-check

before

inserting!

3.

Bad

Solder

Connections:

Constantly

inspect

for

cold

solder

joints

or

solder

bridges

between

pads

while

you

work.

4.

Omitting

a

Part:

Check

off

each

step

in

the

manual

as

you

complete

it.

Soldering

Tips:

Cleanliness

and

good

heat

distribution

are

the

secrets

of

professional

soldering.

Before

you

install

each

part,

inspect

leads

for

oxidation.

If

the

surface

looks

dull,

burnish

it

with

a

pencil

eraser

or

glass-fiber

brush

(available

at

Radio

Shack).

When

soldering,

let

the

iron

tip

contact

both

lead

and

pad

for

about

one

second

before

feeding

solder.

Solder

should

flow

smoothly

into

platethrough

holes,

wetting

all

exposed

surfaces.

Apply

solder

sparingly

and

avoid

touching

solder

wire

directly

to

the

hot

iron

tip.

Desoldering

Tips:

If

you

make

a

mistake

and

need

to

remove

a

part,

grasp

the

component

lead

with

hemostats

and

heat

the

pad

from

the

opposite

side.

Pull

gently--the

lead

should

come

out

(repeat

for

the

other

lead).

If

solder

fills

in

behind,

reheat

the

pad

and

extract

it

with

a

solder-sucker

or

solder

wick.

Parts

damaged

during

extraction

should

be

replaced

(multilayer

capacitors

are

especially

vulnerable

to

removal

damage).

parts.

First,

you'll

identify

inventory

generic

common

to

all

Next,

you'll

inventory

frequency-determining

parts--those

items

that

determine

coverage.

Then,

you’ll

inventory

the

parts

for

installing

and

putting

the

final

touches

on

your

enclosure.

Identify

each

part

carefully,

consulting

the

manual

for

STEP-BY-STEP

ASSEMBLY

Terminology:

When

you

read

the

term

install,

this

means

to

locate,

identify,

dress

the

leads,

and

insert

the

part

into

its

mounting

holes

on

the

PC

board.

Once

a

component

is

mounted,

bend

each

lead

over

and

use

sharp

side-cutters

to

clip

off

the

excess.

Make

sure

lead

ends

don't

touch

other

pads,

tracks,

or

the

groundplane

surface

(see

below).

The

term

solder

means

to

solder

the

part's

leads

in

place,

inspect

for

flaws

or

solder

bridges,

and

nip

off

any

protruding

lead

or

pin

with

a

sharp

pair

of

side

cutters.

All

solder

connections

will

be

made

on

the

bottom

(groundplane)
