General

Description

The

FI-1000

is

a

high

performance

hf

transceiver

providing

dual-channel

reception

on

all

frequencies

between

100

kHz

and

30

MHz,

adjustable

transmitter

power

output

of

up

to

200

watts

on

all

hf

amateur

radio

bands

in

CW,

SSB,

FM,

RTTY

and

Packet

(F1

and

F2)

modes,

and

up

to

50

watts

carrier

in

AM

mode.

A

heavy-duty

AC

power

supply,

automatic

antenna

tuner

and

iambic

electronic

speed

keyer/bug

simulator

are

supplied,.

built

in,

as

standard

accessories,

along

with

eight

IF

filters

for

the

2nd

and

3rd

IFs

of

the

main

and

sub

receivers.

Inside

the

FT-1000,

modular

construction

with

ex-

tensive

use

of

surface

mount

components

on

composite

epoxy

boards

allows

greater

RF

circuit

isolation

and

higher

reliability

than

previous

manufacturing

techni-

ques.

A

squirrel

cage

blower

in

the

heart

of

the

trans-

ceiver

replaces

the

usual

rotary

fan

to

cool

the

interdigital

final

heatsinks

quietly

and

efficiently.

For

exceptionally

clean

receiver

and

transmitter

performance,

the

FT-1000

incorporates

two

10-bit

and

three

8-bit

Direct

Digital

Synthesizers

for

its

local

oscillators

(all

driven

by

a

single

TCXO

master

oscil-

lator),

and

the

operator’s

choice

of

front

end

RF

ampli-

fication

(using

four

FETs

in

a

double

push-pull,

constant-gain

stage),

direct

feed

to

the

double-balanced

quad

FET

ring

mixer,

or

three

levels

of

RF

attenuation

in

6-dB

steps.

Two

receiver

front

ends,

IF

strips

and

vfos

allow

simultaneous

reception

and

display

of

two

different

frequencies,

even

in

different

modes

and

with

different

IF

bandwidths.

Receiver

audio

can

be

com-

pletely

or

partially

mixed,

or

monitored

separately

in

each

ear.

With

independent

bandwidth

and

mode

selec-

tion

for

each

receiver,

plus

an

option

for

separate

anten-

nas

and

bandpass

filters,

a

variety

of

diversity

reception

modes

are

available

when

both

vfos

are

tuned

to

the

same

frequency.

Six

microprocessors

in

the

FT-1000

are

program-

med

to

provide

the

simplest

possible

control

interface

for

the

operator,

even

for

previously

complex

applica-

tions

like

diversity

reception

and

hf

packet.

Two

dual-

speed

tuning

knobs

allow

simple

independent

adjust-

ment

of

the

two

yfos

at

all

times.

Fine

tailoring

of

the

IF

passband

is

made

possible

with

pushbutton

crystal

filter

selection,

concentric

IF

width

and

shift

controls,

and

an

IF

notch

filter.

Separate

keys

are

also

provided

for

band

selection,

and

each

band

key

accesses

two

subband

yfo

frequency/mode/filter

settings

per

band,

so

you

can

keep

separate

vfo

settings

for

two

different

parts

of

the

band,

on

all

bands.

In

addition,

99

scanable

memories

are

provided,

each

of

which

stores

its

own

mode

and

IF

filter

selection,

in

addition

to

frequency,

clarifier

offset

and

scan

status.

The

built-in

automatic

antenna

tuner

includes

39

memories

of

its

own,

auto-

matically

storing

antenna

matching

settings

for

quick

automatic

recall

later.

Of

course

the

front

panel

keypad

can

also

be

used

to

key

in

operating

frequencies

direct-

ly,

Special

installable

options

for

the

over

an

expanded

tem-

and

of

course

a

wide

selection

of

IF

filters

to

complement

the

eight

already

installed

as

standard,

External

Preliminary

Inspection

Inspect

the

transceiver

thoroughly

immediately

upon

opening

the

packing

carton.

Check

to

see

that

all

controls

and

switches

work

freely,

and

inspect

the

cab-

inet

for

any

signs

of

damage.

Make

sure

the

accessory

fuses

and

plugs

pictured

on

page

3

are

included.

If

any

damage

is

found

document

it

completely,

and

contact

the

shipping

company

(or

dealer,

if

you

purchased

it

over

the

counter)

right

away.

Save

the

packing

mat-

erials

in

case

you

need

to

return

the

set

for

service.

If

you

have

purchased

optional

internal

accessories

separately,

install

them

as

described

in

Chapter

6

(page

40).

Power

Connection

The

FT-1000

is

designed

for

operation

from

AC

voltage

only.

Before

connecting

power,

check

the

label

on

the

rear

panel

which

indicates

the

AC

mains

voltage

for

which

your

transceiver

is

currently

set.

If

the

volt-

age

on

this

label

does

not

match

your

AC

mains

volt-

age,

the

taps

on

the

primary

of

the

power

transformer

in

the

transceiver

must

be

rewired,

and

the

fuse

may

have

to

be

changed.

This

requires

only

a

screwdriver

and

is

not

difficult

(see

below),

but

you

should

make

sure

the

transformer

is

wired

correctly

before

connect-

ing

power.

If

you

have

any

doubts

about

the

procedure,

contact

your

dealer

for

assistance.

CAUTION

Permanent

damage

will

result

if

improper

AC

supply

voltage

is

applied

to

the

transceiver.

your

warranty

does

not

cover

damage

caused

by

application

of

improper

supply

voltage,

or

use

of

an

improper

fuse.

We

also

recommend

that

General

Setup

&

AC

Power

Transceiver

Location

To

assure

long

life

of

the

components,

a

primary

consideration

in

setting

up

the

FT-

1000

is

providing

for

adequate

ventilation

around

the

cabinet.

The

cooling

system

of

the

FT-1000

must

be

free

to

draw

cool

air

in

at

the

lower

rear

of

the

transceiver,

and

to

expel

warm

air

out

of

the

upper

rear

panel.

Do

not

place

the

trans-

ceiver

on

top

of

another

heat-generating

device

such

as

a

linear

amplifier,

and

do

not

place

equipment,

books

or

papers

on

top

of

the

transceiver.

Also,

provide

a

few

centimeters

of

space

on

either

side

of

the

transceiver,

if

possible.

Avoid

heating

vents

and

window

locations

that

could

expose

the

transceiver

to

excessive

direct

sunlight,

especially

in

hot

climates.

Grounding

For

protection

from

shock

and

proper

performance,

connect

the

GND

terminal

on

the

rear

panel

to

a

good

earth

ground,

using

a

heavy

braided

cable

of

the

short-

est

length

possible.

All

other

station

equipment

should

be

connected

to

the

same

grounding

cable,

as

close

together

as

practical.

If

you

use

a

computer

with

or

near

the

FT-1000,

you

may

need

to

experiment

with

ground

wiring

to

suppress

computer

noise

in

the

receiver,

Adjusting

the

Front

Feet

The

two

front

feet

of

the

FT-

1000

can

be

set

in

either

of

two

positions.

By

turning

the

knurled

ring

around

a

(retracted)

foot

clockwise,

the

middle

of

the

foot

will

extend

about

one

centimeter

.

Turn

the

ring

as

far

as

it

will

go

(about

1/4-turn)

to

lock

the

extended

foot

in

place.

To

retract

an

extended

foot,

turn

the

knurled

ring

counterclockwise

!/4-turn

while

pressing

on

the

center

of

the

foot.

Adjusting

the

Front

Feet

Antenna

Considerations

Any

antennas

connected

to

the

FT-1000

should

have

coaxial

feedlines

with

50-Q

impedance,

and

in-

clude

a

well-grounded

lightning

arrestor,

For

the

anten-

na

connected

to

the

main

ANT

jack,

the

automatic

anten-

na

tuner

in

the

FT-1000

is

capable

of

matching

antennas

with

an

SWR

of

up

to

3:1

or

more

on

the

amateur

bands

to

the

transmitter.

Nevertheless,

op-

timum

performance

for

both

reception

and

transmis-

sion

will

generally

result

with

an

antenna

designed

to

provide

a

50-Q

unbalanced

resistive

load

at

the

operat-

ing

frequency.

An

antenna

that

is

not

designed

for

resonance

at

the

operating

frequency

may

present

too

high

an

SWR

to

allow

proper

matching

with

the

built-in

antenna

tuner,

in

which

case

the

antenna

itself

should

be

readjusted,

or

an

outboard

antenna

tuner

used.

If

the

tuner

is

unable

to

bring

the

SWR

down

to

an

acceptable

level,

attempting

to

transmit

will

result

in

an

automatic

reduction

in

power

output

and

increased

losses

in

the

feedline.

Operation

under

such

conditions

is

not

re-

commended:

it

is

better

to

install

another

antenna

de-

signed

for

that

band.

Also,

if

your

antenna

has

a

balanced

feedpoint

and

you

use

a

balanced

feedline,

install

a

balun

between

the

feedline

and

the

ANT

jack

of

the

transceiver,

The

same

precautions

apply

to

any

additional

(re-

ceive-only)

antennas

connected

to

the

RX

ANT

jack,

or

to

the

BPF-1

(if

installed),

except

that

neither

of

these

antennas

will

have

the

benefit

of

the

built-in

antenna

tuner.

Therefore,

unless

such

receive-only

antennas

have

an

impedance

near

50

Q

at

the

operating

frequen-

cy,

you

may

need

to

install

an

external

antenna

tuner

to

obtain

optimum

performance.

Interconnection

of

Accessories

The

diagrams

on

the

following

pages

show

inter-

connections

of

various

external

accessories,

If

you

have

any

questions

on

these

accessories

or

connecting

devices

not

shown,

contact

your

dealer

for

advice.

Memory

Backup

The

lithium

memory

BACKUP

switch

inside

the

top

access

panel

is

turned

on

at

the

factory,

allowing

vfo

and

memory

data

to

be

retained

while

power

is

off.

Backup

current

is

miniscule,

so

it

is

not

necessary

to

turn

the

BACKUP

switch

off

unless

the

transceiver

is

to

be

stored

for

an

extended

period.

After

five

or

more

years

of

operation

the

transceiver

may

fail

to

retain

memories,

at

which

time

the

lithium

battery

should

be

replaced.

Contact

your

dealer

for

replacement

of

the

battery,

or

for

instructions

on

how

to

do

so

yourself.
