NSTALLATION

CONNECTION OF ANTENNA AND POWER SUPPLY

The FT-450D is designed for use with any antenna system providing a 50 Ohm resistive impedance at the

desired operating frequency. Every effort should be made to ensure the impedance of the antenna system is as

close as possible to the specified 50-Ohm value. Note that the “G5RV” type antenna does not provide 50-Ohm

impedance on all HF Amateur bands, and an external wide-range antenna coupler must be used with this

antenna type.

Any antenna to be used with the FT-450D must, ultimately, be fed with 50 Ohm coaxial cable. Therefore, when

using a “balanced” antenna such as a dipole, remember that a balun or other matching/balancing device must

be used to ensure proper antenna performance.

AC Power Supply

FT-450D

CAUTION

Permanent damage can result if improper supply

voltage, or reverse-polarity voltage, is applied to

the FT-450D. The Limited Warranty on this trans-

ceiver does not cover damage caused by applica-

tion of AC voltage, reversed polarity DC, or DC volt-

age outside the specified range of 13.8V ±10%.

When replacing fuses, be certain to use a fuse of

the proper rating. The FT-450D requires a 25A fast-

blow fuse.

Warning!

The 100V RF voltage (@100 W/50

Do not touch the TX RF section ab-

solutely while transmitting.

CAUTION

Do not position this apparatus in a location with direct exposure to sunshine.

Do not position this apparatus in a location exposed to dust and/or high humidity.

Do not expose the apparatus to dripping or splashing. Do not put objects with liquids on the apparatus.

Ensure adequate ventilation around this apparatus, so as to prevent heat build-up and possible reduc-

tion of performance due to high heat.

Do not install this apparatus in a mechanically-unstable location, or where objects may fall onto this

product from above.

To minimize the possibility of interference to home entertainment devices, take all precautionary steps

including separation of TV/FM antennas from Amateur transmitting antennas to the greatest extent

possible, and keep transmitting coaxial cables separated from cables connected to home entertain-

ment devices.

Be absolutely certain to install your transmitting antenna(s) such that they cannot possibly come in

contact with TV/FM radio or other antennas, nor with outside power or telephone lines.

Page 12 FT-450D OPERATION MANUAL

NSTALLATION

ABOUT COAXIAL CABLE

Use high-quality 50-Ohm coaxial cable for the lead-in to your FT-450D transceiver. All efforts at providing an

efficient antenna system will be wasted if poor quality, lossy coaxial cable is used. This transceiver utilizes

standard “M” (“PL-259”) type connector.

GROUNDING

The FT-450D transceiver, like any other HF communications apparatus, requires an effective ground system for

maximum electrical safety and best communications effectiveness. A good ground system can contribute to

station efficiency in a number of ways:

It can minimize the possibility of electrical shock to the operator.

It can minimize RF currents flowing on the shield of the coaxial cable and the chassis of the transceiver.

Such currents may lead to radiation, which can cause interference to home entertainment devices or

laboratory test equipment.

It can minimize the possibility of erratic transceiver/accessory operation caused by RF feedback and/or

improper current flow through logic devices.

An effective earth ground system may take several forms. For a more complete discussion, see an appropriate

RF engineering text. The information below is intended only as a guideline.

Typically, the ground connection consists of one or more copper-clad steel rods, driven into the ground. If

multiple ground rods are used, they should be positioned in a “V” configuration, and bonded together at the apex

of the “V” which is nearest the station location. Use a heavy, braided cable (such as the discarded shield from

type RG-213 coaxial cable) and strong cable clamps to secure the braided cable(s) to the ground rods. Be sure

to weatherproof the connections to ensure many years of reliable service. Use the same type of heavy, braided

cable for the connections to the station ground bus (described below).

Inside of the station, a common ground bus consisting of a copper pipe of at least 25 mm (1”) diameter should

be used. An alternative station ground bus may consist of a wide copper plate (single-sided circuit board material

is ideal) secured to the bottom of the operating desk. Grounding connections from individual devices such as

transceivers, power supplies, and data communications devices (TNCs, etc.) should be made directly to the

ground bus using a heavy, braided cable.

Do not make ground connections from one electrical device to an-

other, and thence to the ground bus. This so-called “Daisy-Chain”

grounding technique may nullify any attempt at effective radio fre-

quency grounding. See the drawing at the right for examples of proper

grounding techniques.

Inspect the ground system - inside the station as well as outside - on

a regular basis so as to ensure maximum performance and safety.

Besides following the above guidelines carefully, note that house-

hold or industrial gas lines must never be used in an attempt to

establish an electrical ground. Cold water pipes may, in some in-

stances, help in the grounding effort, but gas lines represent a sig-

nificant explosion hazard, and must never be used.

NSTALLATION

VL-1000 LINEAR AMPLIFIER INTERCONNECTION

INTERFACING TO OTHER LINEAR AMPLIFIER

Be sure that both the FT-450D and VL-1000 are turned off, then follow the installation recommendations con-

tained in the illustration.

The T/R control line is a transistor “open collector” circuit, capable of handling positive amplifier relay coil volt-

ages of up to +50V DC and current of up to 400 mA. If you plan on using multiple linear amplifiers for different

bands, you must provide external band-switching of the “Lin Tx” relay control line from the “TX GND OUT” line

at the LINEAR jack.

Important Note!

Do not exceed the maximum volt-

age or current ratings for the “TX

GND OUT” line at the LINEAR jack.

This line is not compatible with

negative DC voltages, nor AC volt-

ages of any magnitude.

Most amplifier control relay systems

require only low DC voltage/current

switching capability (typically, +12V

DC at 25 ~ 75 mA), and the switch-

ing transistor in the FT-450D will eas-

ily accommodate such amplifiers.

To link the FT-450D and VL-1000

Power switches, set the VL-1000 RE-

MOTE switch to the “ON” position.

Set the front panel’s

INPUT switch to the

“INPUT2”.

Note

ÌPlease refer to the

VL-1000 Operating

Manual for details re-

RECEIVER OPERATION (FRONT END BLOCK DIAGRAM)

The FT-450D includes a wide range of special features to suppress the many types of interference that may be

encountered on the HF bands. However, real world interference conditions are constantly changing, so optimum

setting of the controls is somewhat of an art, requiring familiarity with the types of interference and the subtle

effects of some of the controls. Therefore, the following information is provided as a general guideline for typical

situations, and a starting point for your own experimentation.

The FT-450D’s interference-fighting circuitry begins in its “RF” stages, and continues throughout the entire

receiver section. FT-450D allows configuration of the features described below.

R. FLT (IF Roofing Filters)

The Roofing filter, with a bandwidth of 10 kHz is pro-

vided in the 68 MHz First IF, right after the first mixer.

This filter provides narrow-band selectivity to protect

the following IF and DSP stages, for special operat-

ing circumstances.

CONTOUR Filter (SEE PAGE 28)

The DSP Contour filter provides a unique capability

on the receiver, providing either nulling or peaking of

tunable segments of the receiver passband, so as to

suppress interference or excessive frequency com-

ponents on an incoming signal, or to peak those tun-

able frequency segments. The amount of nulling/

CONTOUR (INTERFERENCE REJECTION “SIGNALS WITHIN 3 KHZ”)

The Contour filtering system provides a gentle perturbation of the IF filter pass band, so as to suppress or

enhance particular frequency components in five steps, thus improving the sound and/or readability of a re-

ceived signal.

1. Press the [DSP] button several times to set the

“>” icon to the “CONTOUR” indicator of the DSP

Graphic Display on the display.

2. Press the [DSP/SEL] knob to engage the con-

tour filter.

3. Press and hold the [DSP/SEL] knob for one sec-

ond to toggle the contour filter’s level between

“null” and “peak”.

4. Rotate the [DSP/SEL] knob to achieve the most

natural-sounding audio reproduction on the in-

coming signal.

The peak position of the contour filter is graphi-

cally-depicted in the “CONTOUR” indicator of the

DSP Graphic Display on the LCD.

5. Press the [DSP/SEL] knob again to increase the

contour filter’s level (“null” or “peak”).

6. To disable the contour filter, press the [DSP/SEL]

button again. The graphic disappears from the

“CONTOUR” indicator of the LCD Display, confirm-

ing that the contour filter is no longer operating.

QUICK POINT:

The steep slopes of the DSP filtering can, when adjusted aggressively, impart an unnatural sound to an incom-

ing signal. Often, a narrow bandwidth is not the key to improving copy. The incoming signal itself may have

undesirable or excessive frequency components. By judicious use of the Contour filter, the “shoulder” of the

passband response may be altered, or components removed from within the passband, allowing the desired

signal to rise above the background noise and interference in a manner not obtainable with other filtering sys-

tems.

SHIFT (INTERFERENCE REJECTION “SIGNALS WITHIN 3 KHZ”)

IF Shift allows you to vary the DSP filter passband higher or lower, without changing the pitch of the incoming

signal, so as to reduce or eliminate interference. Because the carrier tuning frequency is not varied, there is no

need to re-tune the operating frequency when eliminating the interference. The total passband tuning range for

the IF Shift system is ±1 kHz.

WIDTH (INTERFERENCE REJECTION “SIGNALS WITHIN 3 KHZ”)

The IF Width tuning system allows you to vary the width of the DSP IF passband with three steps (FM: two

Using IF Shift and Width Together

The IF Shift and Variable IF Width features

together form a very effective interference-

fighting filtering system.

For example, in Figure “A” you can see how

interference has appeared both on the high

and low sides of the desired signal. By rotat-

ing the [DSP/SEL](WIDTH) knob, as shown

in Figure “B”, the interference from one side

can be eliminated, and by re-positioning the

[SHIFT] knob (Figure “C”), the interference

on the opposite side can be removed, with-

out re-introducing the interference previously

eliminated in Figure “B”.

Advice: For best interference reduction, the

Width and Shift features are the primary tools

you should use. After narrowing the bandwidth

(Width) and/or adjusting the center of the

passband (Shift), the Contour control may

also yield additional signal-enhancement ben-

efits on the net residual bandwidth. What’s

more, the IF Notch Filter (see the next sec-

tion) may also be utilized, in conjunction with

the three other filter systems, to significant

advantage.

RF GAIN

The RF Gain controls provide manual adjustment of the gain levels for the receiver RF and IF stages, to com-

pensate for noise and/or signal strength conditions at the moment.

The [SQL/RF GAIN] knob should, initially, be rotated

to the fully clockwise position. This is the point of maxi-

mum sensitivity, and counter-clockwise rotation will

gradually reduce the system gain.

ADVICE:

As the [SQL/RF GAIN] knob is rotated counter-

clockwise to reduce the gain, the S-meter read-

ing will rise. This indicates that the AGC voltage

being applied to the receiver is increasing (which

causes a reduction in receiver gain).

Rotating the [SQL/RF GAIN] knob control to the

fully counter-clockwise position will essentially dis-

able the receiver, as the gain will be greatly re-

duced. In this case, the S-meter will appear to be

“pegged”. (That is a full-scale reading).

THE

UTOMATIC

NTENNA

UNER

The Automatic Antenna Tuner (hereinafter referred to as the “ATU”) built into each FT-450D is designed to

ensure a 50-Ohm load for the final amplifier stage of the transmitter. We recommend that the ATU be used

whenever you operate on the FT-450D.

ADVICE:

Because the ATU of the FT-450D is located inside the station, it only adjusts the impedance presented to the

transceiver at the station end of your coaxial cable feedline. It does not “tune” the SWR at the antenna feed

point itself. When designing and building your antenna system, we recommend that every effort be made to

ensure a low SWR at the antenna feed point.

The ATU of the FT-450D includes 100 memories for tuning data. Eleven of these memories are allocated,

one per Amateur band, so that each band has at least one setting preset for use on that band. The remaining

89 memories are reserved for the 89 most-recent tuning points, for quick frequency change without the need

to retune the ATU.

The ATU in the FT-450D is designed to match impedances within the range of 16.7 Ohms to 150 Ohms,

corresponding to an SWR of 3:1 or less on the 160 through 6 meter amateur bands. Accordingly, simple

non-resonant whip antennas, along with random-length wires and the “G5RV” antenna (on most bands) may

not be within the impedance matching range of the ATU.

ATU OPERATION

1. Use the Main Tuning Dial knob to set the radio to

the desired operating frequency within the Ama-

teur band.

2. Press the [TUNE] button momentarily to place

the ATU in the transmit line (no adjustment/tun-

ing will occur yet). The “ ” icon will appear

in the display.

QUICK POINT:

The momentary press of the [TUNE] button will

turn the tuner on, and the microprocessor will

automatically select the tuning point closest to

the current operating frequency.

3. Press and hold in the [TUNE] button for one sec-

ond to begin automatic tuning. The transmitter

will be engaged, and the “ ” icon will blink

while tuning is in progress. When the optimum

tuning point has been reached, the radio will re-

turn to receive, and the “ ” icon will again

glow steadily (instead of blinking).

4. To disconnect the ATU from the transmit line,

press the [TUNE] button momentarily. The

“” icon will turn off, confirming that the ATU

has been turned off. In the “Off” mode, the trans-

ceiver will be directly connected to the coaxial

cable connected to your antenna, and will oper-

ate based on whatever impedance is present at

the station end of the coax.

ADVICE:

The ATU circuit is located between the final amplifier

and the rear-panel antenna jack; reception is not af-

fected by the ATU.

QUICK POINTS:

As shipped from the factory, only one ATU alignment

point is saved on each Amateur band. This was

memorized during the final alignment and perfor-

mance verification stages on the production line.

NOTE:

Please check the operating frequency before begin-

ning the tuning process, to be sure you are not inter-

fering with others who may already be using the fre-

quency.

TERMINOLOGY:

Antenna Tuner Memories: The microprocessor of the

ATU makes a note of the positions of the tuning ca-

pacitors and the selected inductors, and stores the

data for each 10 kHz window in which tuning has

occurred. This eliminates the need to re-tune every

time you return to a frequency on which you have

already completed the tuning process.

ABOUT ATU OPERATION

Figure 1 depicts a situation where normal tuning via the ATU has been successfully completed, and the tuning

data has been stored in the ATU memory. The antenna system as seen by the transmitter is shown.

In Figure 2, the operator has changed frequency, and the “ ” icon has appeared. The operator presses and

holds in the [TUNE] button for two seconds to begin impedance matching using the ATU.

If a high SWR condition exists (above 3:1), corrective action must be taken in the antenna system to bring the

impedance closer to 50 Ohms. The ATU will refuse to memorize settings on frequencies where the SWR

exceeds 3:1. A High SWR may indicate a mechanical failure in the feed system, and can lead to the generation

of spurious signals causing TVI, etc.

About ATU Memories

SWR (After tuning) Less than 2:1

The tuner settings are stored in the ATU memory.

SWR (After tuning) Greater than 2:1

Tuning data will not be retained in memory. If you return to the same frequency, the tuning process must be

repeated.

SWR (After tuning) Greater than 3:1

The “ ” icon does not blink, and the tuner settings, if achieved, will not be memorized. Please investi-

gate the high SWR condition and resolve the problem, before attempting further operation using this an-

tenna.

ADVICE:

If you are using the speaker for monitoring, instead of headphones, excessive advancement of the [AF

GAIN] knob can cause feedback to occur. Additionally, this feedback can cause the VOX system to hang up

in a loop, making it impossible to return to receive. Therefore, we recommend the use of headphones, if at

all possible, or the minimum usable setting of the [AF GAIN] knob, if the speaker must be used.

Because the Monitor feature utilizes a sampling of the transmitter’s DSP signal, it can be very useful for

checking the adjustment of the Speech Processor or Microphone Equalizer on SSB, and for checking the

general signal quality on AM and FM.

CW MODE OPERATION

Page 49FT-450D OPERATION MANUAL

CW SPOTTING (ZERO-BEATING)

“Spotting” (zeroing in on another CW station) is a handy technique for ensuring that you and the other station are

precisely on the same frequency.

CW MODE OPERATION

TO USE CW SPOTTING:

In CW mode, while pressing and holding the

[IPO/ATT] button, the Spot tone will be heard and Spot

tone frequency will show in the display. This tone cor-

responds to the pitch of your transmitted signal, and

if you adjust the receiver frequency to match the pitch

of the received CW signal to that of the Spot tone,

your transmitted signal will be precisely matched to

that of the other station.

Release the [IPO/ATT] button to turn the Spot tone off.

USING CW REVERSE

If you experience a difficult interference situation, where an interfering station cannot readily be eliminated, you

may wish to try receiving using the opposite sideband. This may throw the interfering station’s frequency in a

direction that may lend itself more readily to rejection.

1. To start, let’s use a typical example where you

have set the CW mode (using the default “USB”

injection: the “ ” and “ ” icon appear).

2. Press and hold in the [MODE] or [MODE]

button for one second. The “ ” icon appears

instead of “ ”, indicating that the “LSB” injec-

tion side has now been selected.

3. Press and hold in the [MODE] or [MODE]

button, once again, for one second to return to

the normal (USB) injection side and cancel CW

Reverse operation (the “ ” and “ ” icons

appear).

[IPO/ATT] button

In the illustration, Figure A demonstrates the

normal CW injection setup, using the USB

side. In Figure B, CW Reverse has been en-

gaged, so as to receive using LSB-side in-

jection to eliminate interference.

The beneficial effect of switching sidebands

can clearly be seen in this example.

TONE SEARCH SCANNING

In operating situations where you don’t know the CTCSS tone being used by another station or stations, you can

command the radio to listen to the incoming signal and scan in search of the tone being used. Two things must

be remembered in this regard:

You must be sure that your repeater uses the same tone type (CTCSS).

Some repeaters do not pass the CTCSS tone; you may have to listen to the station(s) transmitting on the

repeater uplink (input) frequency in order to allow Tone Search Scanning to work.

To scan for the tone in use:

1. Set the radio up for CTCSS operation (see the

previous discussion). The “ ” icon will

appear on the display.

2. Press and hold the [F] button for one second to

enter the Menu mode. The “ ” icon will ap-

pear on the display.

3. Rotate the [DSP/SEL] knob to select the menu

item “TONE F”.

4. Press the [DSP/SEL] knob to enable adjustment

of the selected Menu Item. The “ ” icon will

be blinking.

5. Press the [SCAN/PMS] button to start scanning

for the incoming CTCSS tone.

6. When the radio detects the correct tone, it will

halt on that tone, and audio will be allowed to pass.

7. Press the [DSP/SEL] knob to lock in that tone.

8. Press and hold the [F] button for one second to

return to normal operation.

NOTE:

If the Tone Scan feature does not detect a tone, it will

continue to scan indefinitely. When this happens, it

may be that the other station is not sending any tone.

You can press the [SCAN/PMS] button to halt the

scan at any time.

CONVENIENT MEMORY FUNCTIONS

The FT-450D contains 500 regular memories, labeled “MEM-001” through “MEM-500”, two Home channels,

one for the HF band and another for the 50 MHz band, two special programmed limit memory pairs, labeled

“MEM-P1L/MEM-P1U” and “MEM-P2L/MEM-P2U”, one QMB (Quick Memory Bank) memory, one Alaska Emer-

gency Frequency Channel (5167.5 kHz), and five 60-meter (5 MHz) band channels (US version only). and seven

60-meter (5 MHz) band channels (UK version only). Each (except the Alaska Emergency Frequency Channel

and 60-meter Band channels, which are fixed.) stores various settings, in addition to the frequency and mode

(See below). By default, the 500 regular memories are contained in one group; however, they can be arranged

in up to 10 separate groups, if desired.

Quick Point:

The FT-450D’s memory channels store the following data:

ÌOperating Frequency

ÌOperating Mode

ÌNARROW / WIDE FM bandwidth status

ÌATT status

ÌIPO status

ÌCONTOUR status and its Peak Frequency

ÌDSP Noise Reduction (DNR) status and its Reduction algorithm selection.

ÌDSP Notch filter (NOTCH) status

ÌRepeater Shift Direction

ÌCTCSS Tone Frequency

IMPORTANT NOTE:

On a rare occasion the memory data may be lost or corrupted due to static electricity, electrical noise or errone-

ous operation. Parts changes or repairs may cause memory loss. Be sure to write down or record your data so

you will be able to restore it.

(PMS)

To limit scanning (and manual tuning) within a particular frequency range, you can use the Programmable

Memory Scanning (PMS) feature, which utilizes two special-purpose memory pairs (“MEM-P1L/MEM-P1U” and

“MEM-P2L/MEM-P2U”). The PMS feature is especially useful in helping you to observe any operating sub-band

limits, which apply to your Amateur license class.

1. Store the Lower and Upper tuning/scanning limit

frequencies into the memory pair “MEM-P1L” and

“MEM-P1U”, respectively, or “MEM-P2L” and

“MEM-P2U”. See page 58 for details regarding

memory storage.

2. Press the [F] button, followed by the [SCAN/PMS]

button.

3. Rotate the [DSP/SEL] knob to select “PMS-1”

“PMS2” or “PMS1+2”.

PMS-1: The scanner will be limited within the

frequency range programmed in the

memory pair “MEM-P1L/MEM-P1U”.

PMS-2: The scanner will be limited within the

frequency range programmed in the

memory pair “MEM-P2L/MEM-P2U”.

PMS-1+2: The scanner will be limited within the

frequency ranges programmed by both

memory pairs (“MEM-P1L/MEM-P1U”

and “MEM-P2L/MEM-P2U”).

If a memory pair is vacant, the PMS-1+2 selec-

tion is not available.

4. Press the [SCAN/PMS] button.

5. Rotate the [SQL/RF GAIN] knob just to the point

where the noise is silenced and the “ ” indi-

cator on the display turns off.

6. Press the [SCAN/PMS] key to initiate upward

scanning (toward higher frequencies or higher

memory channel numbers).

7. If you want to change direction of the scan while it

is underway, rotate the [MAIN DIAL] knob one click

in the opposite direction (in this case, one click

counter-clockwise). You will see the scanner re-

verse direction and scan down in frequency.

You may change the direction of the scanner by

pressing and holding the microphone’s [UP]/

[DWN] key for one second, if you are using the

MH-31A8J Hand Microphone or optional MD-

100A8X Desktop Microphone.

8. In FM/AM mode, when the scanner encounters a

signal strong enough to open the squelch, the

scanner will halt for five seconds, after which scan-

ning will resume.

In the SSB/CW and SSB-based Data modes,

when the scanner encounters a signal strong

enough to open the squelch, the scanner will step

across the signal very slowly, giving you time to

stop the scan, if you like.

ADVICE:

You may select the manner in which the scanner re-

sumes while it has paused on a signal, using Menu

Item “SCN RES” The default “5Sec” setting will cause

VFO mode, just press the [V/M/MW] button.

Note:

ÌThe receive-mode CLARIFIER functions normally

while using this frequency, but variation of the

transmit frequency is not possible. Activation of

“MEM-EMG” or “M-12-EM” does not enable any

other out-of-amateur-band capability on the trans-

ceiver. The full specifications of the FT-450D are

not necessarily guaranteed on this frequency, but

power output and receiver sensitivity should be

fully satisfactory for the purpose of emergency

communication.

ÌIn an emergency, note that a half-wave dipole cut

for this frequency should be approximately 45’3”

on each leg (90’6” total length). Emergency op-

eration on 5167.5 kHz is shared with the Alaska-

Fixed Service. This transceiver is not authorized

for operation, under the FCC’s Part 87, for aero-

nautical communications.

RTTY (RADIO TELETYPE) OPERATION

Most RTTY operation today is accomplished using a TNC or other computer-based system that utilizes AFSK

tones. For RTTY operation using a Terminal Unit (TU) or the “FSK” output from a TNC, please see the discus-

sion below. See also the illustration for details regarding connection to your TU.

SETTING UP FOR RTTY OPERATION

Before commencing RTTY operation, please direct

your attention to the setup steps shown in the chart

to the right.

BASIC SETUP

1. Press the [MODE]/[MODE] buttons several

times to indicate both the “ ” and “ ” icons

on the display. Engage the RTTY operation us-

ing “LSB” injection, which is generally used in the

Amateur service.

2. When you begin typing on your TU or computer

keyboard, the command to transmit should auto-

matically be sent to the transceiver, causing it to

enter the transmit mode.

NOTE:

If you anticipate making data transmissions of longer

than a few minutes, we recommend that you reduce

the transmitter power to 1/2 ~ 1/3 of its normal maxi-

mum via Menu Item “RFPOWER”.

QUICK POINT:

In the FT-450D, “RTTY” is a mode defined as being

an “FSK” mode, whereby the closing and opening of

a keying line (to ground) causes the Mark/Space tones

to alternate. The RTTY mode is not an AFSK based

mode in this transceiver, and the AFSK output tones

from a TNC will not cause Mark/Space shifting to oc-

cur. Use the “Packet” mode for AFSK-based Baudot

and other data modes.

MENU ITEM

RTY SFT (RTTY SHIFT)

RTY TON (RTTY TONE)

RTYRPOL (RTTY RX POLARITY)

RTYTPOL (RTTY TX POLARITY)

AVAILABLE VALUES

170 / 200 / 425 / 850 Hz

1275 / 2125 Hz

NOR / REV

ADVICE:

There is no adjustment of the FSK input level

(FSK IN of the DATA jack) on the rear panel;

please make any needed level adjustments at the

TU side.

The Mark/Space Shift utilized in most Amateur

RTTY operation is 170 Hz. Other shifts may be

configured, however, using Menu Item “RTY SFT”.

The FT-450D is set up for “high tone” operation

(centered on 2125 Hz) by default, but you may

configure it for low tone (1275 Hz) operation us-

ing Menu Item “RTY TON”.

You may find that you are unable to decode some

RTTY stations, even if they are of sufficient sig-

nal strength. If this is observed, there may be a

Mark/Space polarity problem between your sta-

tion and the other station. If so, try setting Menu

Item “RTYRPOL” to “REV” (“Reverse”) to see if

that permits copy. A separate Menu Item permits

reversal of your transmitter’s Mark/Space polar-

ity: “RTYTPOL.”

PACKET OPERATION

Packet operation is easily accomplished on the FT-450D by connecting your TNC (Terminal Node Controller) to

the transceiver, per the illustration.

PACKET SETUP (INCLUDING SUBCARRIER FREQUENCY)

Before operation can commence, change Menu Item

“D TYPE” setting to “USER-L” (for LSB-Based Packet

Operation) or “USER-U” (for USB-Based Packet Op-

BASIC SETUP

1. Press the [MODE]/[MODE] buttons several

times to indicate both the “ ” and “ ” icons

(for LSB-Based Packet) or the “ ” and “ ”

icons (for USB-Based Packet) on the display. En-

gage the Packet operation.

2. When the “transmit” command is received from

the TNC, the transmitter of the FT-450D will au-

tomatically be engaged. Likewise, the command

to return to receive will cause the radio to revert

to the receive mode.

ADVICE:

There is no adjustment of the DATA input level

and DATA output level of the DATA jack on the

rear panel; please make any needed level ad-

justments at the TU side.

During Packet operation via the rear panel’s DATA

jack, the front panel MIC jack is cut off, so you

won’t have a “live microphone” problem during

data operation.

NOTE:

If you anticipate making data transmissions of longer

than a few minutes, we recommend that you reduce

the transmitter power to 1/2 ~ 1/3 of its normal maxi-

mum via Menu Item “RFPOWER”.

AUTOMATIC-MATCHING 200-MEMORY ANTENNA TUNER FC-40 OPERATION

The FC-40 makes use of the control circuitry built into the transceiver, which allows the operator to control and

monitor automatic operation of the FC-40, which mounts near the antenna feedpoint. The FC-40 uses specially

selected, thermally-stable components, and is housed in a waterproof case to withstand severe environmental

conditions with high reliability.

A carefully-chosen combination of solid-state switching components and high-speed relays allows the FC-40 to

match a wide variety of antennas to within a 2:1 SWR on any amateur band frequency (160 through 6 meters),

typically in less than eight seconds. Transmitter power required for matching may be as little as 4 - 60 Watts, and

matching settings are automatically stored in memory for instant recall when the same frequency range is

selected later.

Please see the manual of FC-40 for detailed information.

Interconnections to FT-450D

After mounting the FC-40, connect the cables from the tuner to the ANT and TUNER jacks on the rear panel of

the FT-450D Transceiver.

Installation

The optional FC-40 Automatic Antenna Tuner provides automatic tuning of a coaxial line so as to present a

nominal 50-ohm impedance to the FT-450D’s, HF/50 MHz antenna port.

Before operation can begin, you must instruct the FT-450D’s microprocessor that the FC-40 is being used. This

is done using the Menu Mode:

1. Press and hold the [F] button for one second to

enter the Menu Mode.

The “ ” icon will appear in the display.

2. Rotate the [DSP/SEL] knob to select the Menu

Item “TUNER.”

3. Press the [DSP/SEL] knob to enable this selected

Menu Item.

4. Rotate the [DSP/SEL] knob to change the setting

AUTOMATIC-MATCHING 200-MEMORY ANTENNA TUNER FC-40 OPERATION

Note

ÌPlease connect a good earth ground to the GND terminal of FC-40.

ÌThe carrier signal transmits continuously while tuning is in progress. Please monitor the operating frequency

before beginning the tuning process. Be sure you are not interfering with others who may already be using

the frequency.

ÌIt is normal to hear the sound of the relays while tuning is in progress.

ÌIf the impedance cannot be matched by the FC-40 better than 2:1, and the “ ” icon will blink, the micropro-

cessor will not retain the tuning data for that frequency, as the FC-40 presumes that you will want to adjust or

repair your antenna system to correct the high SWR condition.
