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.

Permanent damage can result if improper supply

CAUTION

voltage, or reverse-polarity voltage, is applied to the FT-450D. The Limited Warranty on this transceiver does not cover damage caused by application of AC voltage, reversed polarity DC, or DC voltage 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 fastblow fuse.

AC Power Supply

Warning!

The 100V RF voltage (@100 W/50 Ω) is applied to the TX RF section of the transciver while transmitting.

Do not touch the TX RF section absolutely while transmitting.

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.

TYPICAL PL-259 INSTALLATION

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 another, and thence to the ground bus. This so-called “Daisy-Chain” grounding technique may nullify any attempt at effective radio frequency 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

PROPER GROUND CONNECTION

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

Besides following the above guidelines carefully, note that household or industrial gas lines must never be used in an attempt to establish an electrical ground. Cold water pipes may, in some instances, help in the grounding effort, but gas lines represent a significant explosion hazard, and must never be used.

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

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 received signal.

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

“CONTOUR” Indicator

“>” icon to the “CONTOUR” indicator of the DSP Graphic Display on the display.

2. Press the [DSP/SEL] knob to engage the contour filter.

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

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.

Refer to Figure “B”, this shows a “indentation” of the contour filter is center of a passband. Counter-clockwise rotation (to the left) of the [DSP/SEL] knob causes the indentation to move toward a lower frequency within the passband, while clockwise rotation (to the right) causes the indentation to move toward a higher frequency within the passband. By removing interference or unwanted frequency

QUICK POINT:

The steep slopes of the DSP filtering can, when adjusted aggressively, impart an unnatural sound to an incoming 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 systems.

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.

The IF Width tuning system allows you to vary the width of the DSP IF passband with three steps (FM: two steps), so as to eliminate interference. Moreover, the bandwidth may actually be expanded from its default

setting, should you wish to enhance incoming signal fidelity when interference on the band is low.

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

Using IF Shift and Width Together

The IF Shift and Variable IF Width features together form a very effective interferencefighting 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 rotating 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, without re-introducing the interference previously eliminated in Figure “B”.

The default bandwidths, and total bandwidth adjustment range, will vary according to the operating mode:

SSB Mode: 1.8 kHz / 2.4 kHz / 3.0 kHz

(Nominal: 2.4 kHz).

CW Mode: 300 Hz / 500 Hz / 2.4 kHz

(Nominal: 2.4 kHz).

DATA Mode:300 Hz / 2.4 kHz / 3.0 kHz

(Nominal: 2.4 kHz).

AM Mode: 3.0 kHz / 6.0 kHz / 9.0 kHz

(Nominal: 6.0 kHz).

FM Mode: 2.5 kHz / 5.0 kHz

(Nominal: 5.0 kHz).

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 benefits on the net residual bandwidth. What’s more, the IF Notch Filter (see the next section) 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 compensate 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 maximum 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 reading 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 disable the receiver, as the gain will be greatly reduced. In this case, the S-meter will appear to be “pegged”. (That is a full-scale reading).

SING THE

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 Amateur band.

2. Press the [TUNE] button momentarily to place the ATU in the transmit line (no adjustment/tuning 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 second 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 return 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 transceiver will be directly connected to the coaxial cable connected to your antenna, and will operate based on whatever impedance is present at the station end of the coax.

[

TUNE] button

ADVICE:

The ATU circuit is located between the final amplifier and the rear-panel antenna jack; reception is not affected 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 performance verification stages on the production line.

NOTE:

Please check the operating frequency before beginning the tuning process, to be sure you are not interfering with others who may already be using the frequency.

TERMINOLOGY:

Antenna Tuner Memories: The microprocessor of the ATU makes a note of the positions of the tuning capacitors 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.

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 investigate the high SWR condition and resolve the problem, before attempting further operation using this antenna.

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.

)

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 corresponds 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.

[

IPO/ATT] button

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” injection side has now been selected.

In the illustration, Figure A demonstrates the normal CW injection setup, using the USB side. In Figure B, CW Reverse has been engaged, so as to receive using LSB-side injection to eliminate interference.

The beneficial effect of switching sidebands can clearly be seen in this example.

FM MODE OPERATION

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 appear 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.

MEMORY OPERATION

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 Emergency 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:

Ì Operating Frequency Ì Operating Mode Ì NARROW / WIDE FM bandwidth status Ì ATT status Ì IPO status Ì CONTOUR status and its Peak Frequency Ì DSP Noise Reduction (DNR) status and its Reduction algorithm selection. Ì DSP Notch filter (NOTCH) status Ì Repeater Shift Direction Ì CTCSS Tone Frequency

IMPORTAN T NOTE:

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

Note:

Ì The 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 transceiver. 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.

Ì In 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 operation on 5167.5 kHz is shared with the AlaskaFixed Service. This transceiver is not authorized for operation, under the FCC’s Part 87, for aeronautical communications.

AUTOMATIC POWER-OFF (APO

The “Automatic Power-Off” (APO) feature will turn the radio completely off after a user-defined period of PTT or key/button inactivity. If you do not press any front panel keys or buttons, rotate the [MAIN DIAL] knob, use the

microphone’s keys and buttons, or transmit, and so long as the transceiver is not scanning or engaged in priority monitoring, the radio will shut itself off after the specified time period. The available selections for the time before power-off are 1 - 12 hours (1 hour step), as well as APO Off. This feature is useful in minimizing battery drain in a mobile installation if you forget to turn the transceiver off.

1. Press and hold the [F] button for one second to enter the Menu mode again. The “ ” icon will appear on the display.

2. Rotate the [DSP/SEL] knob to select the menu item “APO”.

3. Press the [DSP/SEL] knob to enable adjustment of this menu item. The “ ” icon will be blinking.

4. Rotate the [DSP/SEL] knob to select desired “Switch-off” time or “off.” You may press [RCL/HOME] button to reset the APO to the factory default.

5. Press the [DSP/SEL] knob. The “ ” icon returns to appear continuously.

PERATION

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 discussion 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.

1. Press the [MODE]/[MODE] buttons several times to indicate both the “ ” and “ ” icons on the display. Engage the RTTY operation using “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 automatically 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 maximum 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 occur. Use the “Packet” mode for AFSK-based Baudot and other data modes.

BASIC SETUP

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 using Menu Item “RTY TON”.

 You may find that you are unable to decode some

RTTY stations, even if they are of sufficient signal strength. If this is observed, there may be a Mark/Space polarity problem between your station 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 polarity: “RTYTPOL.”

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.
