    INSTALLATION
    CONNECTION OF ANTENNA AND POWER SUPPLY
    The FT-450 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-450 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.
    CAUTION

    ANTENNA

    Permanent damage can result if improper supply
    voltage, or reverse-polarity voltage, is applied to
    the FT-450. 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-450 requires a 25A fastblow fuse.

    Use high-quality 50-Ohm coaxial cable for the lead-in to your FT-450 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.

    INSTALLATION
    GROUNDING
    The FT-450 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 socalled “Daisy-Chain” grounding technique may nullify any attempt at effective radio frequency grounding. See
    the drawing below 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 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.

    Do not exceed the maximum voltage or current ratings for the “TX

    Most amplifier control relay systems
    require only low DC voltage/current
    switching capability (typically, +12V
    DC at 25 ~ 75 mA), and the switching transistor in the FT-450 will easily accommodate such amplifiers.

    Important Note!

    HF Antenna

    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.

    CONVENIENCE FEATURES
    RECEIVER OPERATION (FRONT END BLOCK DIAGRAM)
    The FT-450 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-450’s interference-fighting circuitry begins in its “RF” stages, and continues throughout the entire receiver section. FT-450 allows configuration of the features described below.

    R. FLT (IF Roofing Filters)

    IF NOTCH (SEE PAGE 31)

    The Roofing filter, with a bandwidth of 10 kHz is provided 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 operating circumstances.

    The IF Notch filter is a high-Q notch filter that can
    significantly reduce, if not eliminate, an interfering
    carrier.

    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 components on an incoming signal, or to peak those tunable frequency segments. The amount of nulling/
    peaking, and the bandwidth over which it is applied,
    are adjustable via the Menu.

    IF SHIFT (SEE PAGE 29)

    DNR (DIGITAL NOISE REDUCTION) (SEE PAGE 32)
    The DSP’s Digital Noise Reduction (DNR) feature utilizes eleven different mathematical algorithms to analyze and suppress different noise profiles encountered
    on the HF/50 MHz bands. Choose the selection that
    provides the best noise suppression, which concurrently will allow the signal to rise up out of the noise.

    AGC (SEE PAGE 27)
    The AGC system is highly adaptable to changing signal and fading characteristics, making reception possible under the most difficult conditions.

    The passband center frequency response of the IF
    DSP filtering may be adjusted using this control.

    IF WIDTH (SEE PAGE 30)
    The width of the IF DSP filtering may be adjusted
    using this control.

    CONVENIENCE FEATURES
    ATT/IPO (ADJUST THE RECEIVING SENSITIVITY)
    You may reduce the receiving signal strength to 20 dB when extremely strong local signals or high noise degrade reception. You may optimize the characteristics of the receiver front-end, for best reception, depending on
    the noise levels and the signal strengths.
    Press the [ATT/IPO] button several times to set the
    desired selection, per the chart below.
    ATT: OFF, IPO: OFF

    Attenuator is OFF, and the incoming
    signal is amplified by the RF preamplifier.

    ATT: ON, IPO: OFF

    Attenuator is ON, (the incoming signal
    is reduced by 20 dB) and the incoming signal is amplified by the RF preamplifier.
    Attenuator is OFF, and the incoming
    signal bypasses the RF preamplifier,
    yielding direct feed to the first mixer.

    The selection will be indicated in the Block Diagram
    on the display.

    NOTE
    An attenuator is always “ON” between 30kHz
    and 1.7MHz.

    NOISE BLANKER (INTERFERENCE REJECTION “SIGNALS WITHIN 3 KHZ”)
    The FT-450 includes an effective Noise Blanker, which can significantly reduce noise caused by automotive
    ignition systems.
    1. Press the [ NB ] button to activate the Noise
    Blanker.

    CONVENIENCE FEATURES
    AGC (TOOL FOR COMFORTABLE AND EFFECTIVE RECEPTION)
    The AGC system is designed to help compensate for fading and other propagation effects, with characteristics
    that can be of particular value on each operating mode. The basic objective of AGC is to maintain a constant
    audio output level once a certain minimum threshold of signal strength is achieved.
    Press the [AGC] button repeatedly to select the desired receiver-recovery time constant. The AGC status is indicated in the Block Diagram displayed on
    the display. For most operations, we recommend the
    “AUTO” mode. You may disable the AGC by pressing and holding in the [AGC] button for one second.
    AUTO

    Sets the receiver-recovery time automatically
    depending on the operating mode.

    FAST

    Sets the receiver-recovery time to fast.
    This mode is suitable for CW/DATA reception.
    Sets the receiver-recovery time to slow.
    This mode is suitable for SSB/AM reception.

    Block Diagram

    NOTE:
    Normally, the “AUTO” selection is satisfactory for most
    situations, but in the event of operation on a crowded
    band where you wish to receive a weak signal, you
    may wish to change the setting (to FAST, for example). The “AUTO” mode selections are:

    ADVICE:
    If the AGC receiver-recovery time is set to “Off”
    by pressing and holding in the [AGC] button,
    the S-meter will no longer deflect. Additionally, you
    will likely encounter distortion on stronger signals, as
    the IF amplifiers and the following stages are probably being overloaded.

    CONVENIENCE FEATURES
    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 received 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 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 incoming signal.
    The peak position of the contour filter is graphically-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, confirming 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
    components on the incoming signal, it is possible to make the desired signal rise out of
    the background noise/interference, enhancing intelligibility.

    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.

    CONVENIENCE FEATURES
    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
    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
    “>” icon to the “WIDTH” indicator of the DSP
    Graphic Display on the display, to enable adjustment of the bandwidth by the [DSP/SEL] knob.
    2. Rotate the [DSP/SEL] knob to adjust the bandwidth. Counter-clockwise rotation reduces the
    bandwidth, while clockwise rotation increases the
    bandwidth.

    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”.
    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 counterclockwise 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).

    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
    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
    [ATT/IPO] 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.
    [ATT/IPO] button

    Release the [ATT/IPO] 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 ]

    In the illustration, Figure A demonstrates the

    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 [PMS/SCAN] 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.

    MEMORY OPERATION
    CONVENIENT MEMORY FUNCTIONS
    The FT-450 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 “MEMP1L/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. 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-450’s memory channels store the following data:
    ❒ Operating Frequency
    ❒ Operating Mode
    ❒ NARROW / WIDE FM bandwidth status
    ❒ ATT status
    ❒ IPO status
    ❒ CONTOUR status and its Peak Frequency
    ❒ DSP Noise Reduction (DNR) status and its Reduction algorithm selection.
    ❒ DSP Notch filter (NOTCH) status
    ❒ Repeater Shift Direction
    ❒ CTCSS Tone Frequency
    IMPORTANT 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.

    “Memory Tune” mode, this is similar to VFO operation. So long as you do not over-write the contents of
    the current memory, Memory Tune operation will not
    alter the contents of the memory channel.
    1. Press the [MW/V/M] button, if necessary, to enter
    the Memory mode.
    2. Rotate the [MAIN DIAL] knob. You will now observe that the memory channel’s frequency is
    changing.
    The “M-TUNE” notation will replace the Memory
    Channel Number, indicating you are in the
    “Memory Tune” mode.
    During Memory Tune operation, you may change
    operating modes, and engage and offset the Clarifier, if desired.
    3. Press the [MW/V/M] button momentarily to return
    to the originally-memorized frequency of the current memory channel. One more press of the
    [MW/V/M] button will return you to VFO operation.

    Note:
    ❒ 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-amateurband capability on the transceiver. The full specifications of the FT-450 are not necessarily guaranteed on
    this frequency, but power output and receiver sensitivity should be fully satisfactory for the purpose of emergency communication.
    ❒ 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 Alaska-Fixed Service. This
    transceiver is not authorized for operation, under the FCC’s Part 87, for aeronautical 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 discussion below. See also the illustration for details regarding connection to your TU.

    your attention to the setup steps shown in the chart
    to the right.

    170 / 200 / 425 / 850 Hz
    1275 / 2125 Hz
    NOR / REV
    NOR / REV

    BASIC SETUP
    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-450, “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.

    Page 72

    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-450 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.”

    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-

    eration), to configure your radio for the data mode to
    be used.

    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. Engage the Packet operation.
    2. When the “transmit” command is received from
    the TNC, the transmitter of the FT-450 will automatically 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 adjustments 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.

    AUTOMATIC ANTENNA TUNER ATU-450 OPERATION
    The ATU-450 Automatic Antenna Tuner responds to control commands from the FT-450 Transceiver, providing
    microprocessor-based impedance matching on the 160 through 6 meter amateur bands. The impedance matching
    range is from 16.5 ohms to 150 ohms (up to 3:1 SWR). Accordingly, the ATU-450 should not be expected to
    match “Long wire” type antennas unless you have taken specific design steps to ensure that the impedance
    presented to the FT-450 is within this specification.

    Important Note
    ❒ Please be careful to avoid any short-circuit to any metal object.
    ❒ Please install with great care to prevent injuries from sharp corners of metal objects.
    ❒ Please practice standard grounding techniques and do not touch semiconductor components unnecessarily
    to avoid breakage or damage by static electricity etc.

    Notes
    The ATU-450 and ATAS-120A Active Tuning Antenna System cannot be connected at the same time.
    The carrier signal transmits continuously while tuning is in progress. Please check the operating frequency
    before beginning the tuning process. Be sure you are not interfering with others who may already be using
    the frequency.
    It is normal to hear the sound of the relays while tuning is in progress.
    If the ATU-450 does not tune (the “
    ” icon does not blink) even though you have pressed the [TUNE]
    switch within the amateur band, it may be because the antenna or its coaxial cable have a serious problem
    (very high or low impedance due to an “Open” or “short” circuit condition. Please check the antenna and
    coaxial cable if this happens.
    The ATU-450 only adjusts the impedance presented to the transceiver at the station end of your coaxial cable
    feed line. It does not “tune” the SWR at the antenna feed point itself. When designing and building your
    antenna system, we recommended that every effort be made to ensure a low SWR at the antenna feed point.
    Do not connect an antenna or feed cable that is not designed for 50-ohm impedance.
    The impedance matching range of the ATU-450 is from 16.5 ohms to 150 ohms (up to 3:1 SWR). Accordingly, the ATU-450 should not be expected to match “long wire” type antennas unless you have taken specific
    design steps to ensure that the impedance presented to the FT-450 is within this specification.

    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.
