    GENERAL DESCRIPTION
    Congratulations on the purchase of your Yaesu amateur
    transceiver ,f this is your ¿rst rig, or if Yaesu eTuipment
    is already the backbone of your station, rest assured
    your transceiver will provide many hours of operating
    pleasure for years to come.
    The FTDX1200 is an elite-class HF transceiver providing exceptional performance both on transmit and receive. The FTDX1200 is designed for the most competitive operating situations, whether you primarily operate
    in contest, ';, or digital-mode environments.
    Built on the foundation of the popular FTDX9000 transceiver, and carrying on the proud tradition of the FT1000 series, the FTDX1200 provides up to 100 Watts
    of power output on 66B, CW, and F0  Watts $0
    carrier. 'igital 6ignal 3rocessing '63 is utili]ed
    throughout the design, providing leading-edge transmitter and receiver performance.
    For exceptional protection from strong signal interference, the optional 5F —Tuning .its may be connected
    via the rear panel. The 5F —Tuning .its provide extraordinarily sharp selectivity and protect your receiver from
    close-in interference on a crowded band.
    ,n the front end, you may select one of two 5F preampli¿ers, or ,32 ,ntercept 3oint 2ptimi]ation, providing
    direct feed to the ¿rst mixer. Three levels of 5F attenuation are available in 6-dB steps.
    The FTDX1200 receiver utili]es '63 ¿ltering, incorporating many of the features of the FTDX9000, such as
    9ariable Bandwidth, ,F 6hift, and 3assband Contour
    tuning. $lso provided are 'igital 1oise 5eduction, 'igital $uto-1otch Filtering and a manually tuned ,F 1otch
    ¿lter.
    2n the transmit side, the Yaesu exclusive Three-Band
    3arametric 0icrophone (Tuali]er allows precise and
    flexible adjustment of the waveform created by your
    voice and microphone. The audio $mplitude, Center
    FreTuency, and Bandwidth are adjusted separately for
    the low, mid-range, and high-freTuency audio spectrum.
    The transmitted bandwidth may also be adjusted.

    FreTuency setup is straightforward on the FTDX1200.
    (nter freTuency directly for 9F2-$. 6eparate keys are
    available for band selection. (ach band key provides
    three separate 9F2 settings for three different parts of
    each band. You may create three independent 9F2 settings of freTuency, mode, and ¿lter for each band.
    ,n addition,  memories are provided to store FreTuency, 0ode, ,F ¿lter selection, Clari¿er offset, and 6canskip status. What¶s more, five Tuick-recall “40B”
    memories can instantly store operational settings at the
    push of a button.
    The built-in antenna tuner includes 100 memories that
    automatically store antenna matching settings for rapid,
    later automatic recall.
    Interfacing for digital modes is extremely simple with
    the FTDX1200, thanks to the dedicated 5TTY'$T$
    connection jack on the rear panel. 2ptimi]ation of the
    ¿lter passband, '63 settings, carrier insertion point, and
    display offset for digital modes, is possible via the 0enu
    programming system.
    $dvanced technology is only part of the FT DX1200
    story. Yaesu stands behind our products with a worldwide network of dealers and service centers. We greatly
    appreciate your investment in the FTDX1200, and we
    look forward to helping you get the most enjoyment
    from your new transceiver. 3lease feel free to contact
    your nearest dealer, or one of Yaesu¶s national headTuarters of¿ces, for technical advice, interfacing assistance,
    or accessory recommendation. Watch Yaesu 8.6.$.¶s

    INSTALLATION AND INTERCONNECTIONS
    ANTENNA CONSIDERATIONS
    The FTDX1200 is designed for use with any antenna system providing a 0 2hm resistive impedance at the desired operating freTuency. While minor excursions from the 0-2hm speci¿cation are of no conseTuence, if the Standing Wave
    5atio SW5) present at the $ntenna jack is greater than 31, the transceiver¶s $utomatic $ntenna Tuner may not be able
    to reduce the impedance mismatch to an acceptable value.
    (very effort should be made to ensure that the impedance of the antenna system be as close as possible to the speci¿ed
    0-2hm value. 1ote that the “G5V” type antenna does not provide a 0-2hm impedance on all HF $mateur bands. $n
    external wide-range antenna coupler must be used with this antenna type.
    $ny antenna to be used with the FTDX1200 must be fed from the transceiver with 0 2hm coaxial cable. Therefore,
    when using a “balanced” antenna such as a dipole, remember that a balun or other matchingbalancing device must be
    used to ensure proper antenna performance.
    The same precautions apply to any additional receive-only) antennas connected to the antenna jacks. if your receiveonly antennas do not have impedance near 0 2hms at the operating freTuency, you may need to install an external antenna tuner to obtain optimum performance.

    ABOUT COAXIAL CABLE
    Use high-Tuality 0-2hm coaxial cable for the lead-in to your FTDX1200 transceiver. $ll efforts at providing an ef¿cient antenna system will be wasted if poor Tuality, lossy coaxial cable is used. This transceiver utili]es standard “0”
    “3L-”) type connectors.

    INSTALLATION AND INTERCONNECTIONS
    GROUNDING
    The FTDX1200 transceiver, like any other HF communications apparatus, reTuires an effective ground system for maximum electrical safety and best communications effectiveness. $ good ground system can contribute to station ef¿ciency
    in a number of ways
    ˆ It can minimi]e the possibility of electrical shock to the operator.
    ˆ It can minimi]e 5F currents Àowing 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 eTuipment.
    ˆ It can minimi]e the possibility of erratic transceiveraccessory operation caused by 5F feedback andor improper
    current Àow through logic devices.
    $n effective earth ground system may take several forms. for a more complete discussion, see an appropriate 5F 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” con¿guration and bonded together at the base of the “V” which
    is nearest the station location. Use a heavy, braided cable such as the discarded shield from type 5G-13 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 the station, a common ground bus consisting of a copper pipe of at least  mm diameter should be used. $n 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 transceivers, power supplies, and data communications devices T1Cs, etc.) should be made directly to the ground bus using a heavy, braided cable.
    'o not “'aisy-Chain” ground connections from one electrical device to another and thence to the ground bus. This
    method may nullify any attempt at effective radio freTuency grounding. See the drawing below for examples of proper
    grounding techniTues.
    Inspect the ground system - inside the station as well as outside - on a regular basis to ensure continued 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 signi¿cant explosion ha]ard, and must never be used.

    3lease follow the outline in the illustration regarding the proper connection of antenna coaxial cables, as well as the 'C
    power cable. The 'C power connector for the FTDX1200 must only be connected to a 'C source providing 13.8 Volts 'C
    “10 ), and capable of at least 3 $mperes of current. $lways observe proper polarity when making 'C connection
    The RED DC power lead connects to the Positive (+) DC terminal.
    The BLACK DC power lead connects to the Negative (–) DC terminal.
    To prevent damage from
    lightning, atmospheric electricity, electrical shock etc., please
    provide a good earth ground.
    Use a short,
    thick, braided
    cable to connect your station
    eTuipment to the
    buried ground rod or alternative earth
    ground system).

    Check the DC voltage and current rating
    (+13.8 V, 23 A) of the power
    supply before connecting to the
    transceiver.

    We recommend the use of the FP-1030A US$ market only) $C 3ower Supply. 2ther models of power supplies may
    be used with the FTDX1200, but the 13.8 V'C input voltage, 3 $mpere current capability, and 'C cable polarity
    guidelines described above must be strictly followed.
    1ote that other manufacturers may use the same type of 'C power connections as does your FTDX1200 transceiver,
    however, the wiring con¿guration may be different from that speci¿ed for your transceiver. Serious damage can be
    caused if improper 'C connections are made consult with a Tuali¿ed service technician when in doubt.
    The 100 V 5F voltage #100 W0-ohm) is applied to the T; 5F section of the transceiver while transmitting.
    'o not touch the T; 5F section absolutely while transmitting.
    3ermanent damage can result when improper supply voltage, or reverse-polarity voltage, is applied to the
    FTDX1200. The Limited Warranty on this transceiver does not cover damage caused by application of $C voltage, reverse polarity 'C, or 'C voltage outside the speci¿ed range of 13.8 V “10 . When replacing fuses, be certain
    to use a fuse of the proper rating. The FTDX1200 reTuires a  $ blade fuse.
    ADVICE:
    ˆ 'o not position the FTDX1200 in a location with direct exposure to sunshine.
    ˆ 'o not position the FTDX1200 in a location exposed to dust andor high humidity.
    ˆ (nsure adeTuate ventilation around the FTDX1200, to prevent heat build-up and possible reduction of performance
    due to high heat.
    'o
    not install the FTDX1200 on an unstable desk or table. 'o not place in a location where objects may fall onto it from above.
    ˆ
    ˆ To minimi]e the possibility of interference to home entertainment devices, take all precautionary steps including
    separation of TVF0 antennas from $mateur transmitting antennas to the greatest extent possible, and keep transmitting coaxial cables separated from cables connected to home entertainment devices.
    ˆ (nsure that the 'C power cord is not subject to undue stress or bending, which could damage the cable or cause it to
    be accidentally unplugged from the rear panel DC IN jack.
    ˆ Be certain to install your transmitting antenna s) so they cannot possibly come in contact with TVF0 radio or other
    antennas, or with power or telephone lines.

    The FTDX1200 includes many features for the CW operator. These functions will be detailed in the “2peration” section
    later. Besides the built-in (lectronic .eyer, two key jacks are provided, one on the front and one on the rear panel, for
    convenient connection to keying devices.
    The 0enu selections allow you to con¿gure the front and rear panel KEY jacks according to the device you wish to connect. For example, you may connect your keyer paddle to the front panel KEY jack, and use 0enu item “018 F KEYER
    TYPE” for paddle input, and also connect the keying line from your personal computer which emulates a “straight key”)
    to the rear panel KEY jack, and con¿gure the rear panel jack using 0enu item “020 R KEYER TYPE”.
    Both KEY jacks on the FTDX1200 utili]e “3ositive” keying voltage. .ey-up voltage is approximately 3.3V 'C, and
    key-down current is approximately 4 m$. When connecting a key or other device to the KEY jacks, use only a 3-contact “stereo”) 14” phone plug a -contact plug will place a short between the ring and grounded) shaft of the plug,
    resulting in a constant “key-down” condition in some circumstances.

    CLAR (CLARIFIER) OPERATION
    The [RX CLAR], [TX CLAR], [CLEAR] buttons and [VFO-B/CLAR] knob are used to offset the receive freTuency,
    the transmit freTuency, or both, from their settings on the VF2-$ freTuency. Four small numbers on the TFT 'isplay
    show the current Clari¿er offset. The Clari¿er controls on the FTDX1200 are designed to allow you to preset an offset up
    to “. kH]) without actually retuning, and then to activate it via the Clari¿er [RX CLAR] and [TX CLAR] buttons.
    This feature is ideal for following a drifting station, or for setting the small freTuency offsets sometimes utili]ed in ';
    “Split” work.
    [CLEAR] Button

    Here is the techniTue for utili]ing the Clari¿er
    1. 3ress the [RX CLAR] button. The “RX” notation
    will appear in the TFT 'isplay, and the programmed
    offset will be applied to the receive freTuency.
    . 5otation of the [VFO-B/CLAR ] knob will allow
    you to modify your initial offset on the Ày. 2ffsets of
    up to “. kH] may be set using the Clari¿er.

    ADVICE:
    ˆ Turning the Clari¿er off merely cancels the application of the programmed offset from the receive and
    or the transmit freTuencies. To clear the Clarifier
    offset, and reset it to “]ero,” press the [CLEAR] button. The programmed offset is displayed in the small
    multi-channel window of the freTuency display.

    RECEIVER OPERATION (FRONT END BLOCK DIAGRAM)
    The FTDX1200 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, reTuiring 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 FTDX1200 interference-¿ghting circuitry begins in its “5F” stages, and continues throughout the entire receiver
    section. FTDX1200 allows con¿guration of the features described below.

    R. FLT (,)5RR¿QJ)LOWHUV)

    IF NOTCH

    Three 5oofing filters, of 1 kH], 6 kH], and 3 kH]
    bandwidths, are provided in the First IF, right after the
    first mixer. These filters are automatically selected to
    provide narrow-band selectivity to protect the following
    IF and 'S3 stages. The automatically selected ¿lter may
    be manually changed by the operator, if desired, for special operating circumstances.

    The IF 1otch ¿lter is a high-Q notch ¿lter that can eliminate, or signi¿cantly reduce an interfering carrier.

    DNF ('LJLWDO1RWFK¿OWHU)
    When multiple interfering carriers are encountered during reception, the 'igital 1otch Filter can signi¿cantly
    reduce the level of these signals.

    DNR (Digital Noise Reduction)

    CONTOUR Filter
    The 'S3 Contour filter has the uniTue ability to provide either a null or a peak in tunable segments of the
    receiver passband. You may suppress interference and
    excessive freTuency components on an incoming signal,
    or you may peak those tunable freTuency segments. The
    level of the null or peak, and the bandwidth, over which
    it is applied, are adjustable via the 0enu.

    IF SHIFT
    The passband center freTuency of the IF 'S3 ¿lter may
    be moved up or down by adjusting this control.

    The 'S3’s 'igital 1oise 5eduction '15) feature utili]es 1 different mathematical algorithms to analy]e
    and suppress different noise pro¿les encountered on the
    HF0 0H] bands. Choose the selection that provides
    the best noise suppression, and allows the signal to rise
    up out of the noise.

    AGC
    The $GC system is highly adaptable to changing signal
    and fading characteristics, making reception possible
    under the most dif¿cult conditions.

    make reception more comfortable, important especially during long QS2s. When looking for weak signals on a Tuiet
    band, you will want maximum sensitivity, so the I32 should be disabled and the [ATT] button should be set to “2FF.”
    This situation is typical during Tuiet times on freTuencies above 1 0H], and when using a small or negative-gain
    receiving antenna on other bands.

    TOOLS FOR COMFORTABLE AND EFFECTIVE RECEPTION
    RF GAIN
    The 5F Gain control provides manual adjustment of the gain levels for the receiver 5F and IF stages, to account for
    noise and signal strength conditions at the moment.
    1. The [ RF/SQL ] knob should, initially, be rotated
    to the fully clockwise position. This is the point of
    maximum sensitivity.
    . Counter-clockwise rotation of the [RF/SQL] knob
    will gradually reduce the system gain.
    ADVICE:
    ˆ $s the [RF/SQL] knob is rotated counterclockwise
    to reduce the gain, the S-meter reading will rise. This
    indicates that the $GC voltage being applied to the
    receiver is increasing this causes a reduction in receiver gain).
    ˆ 5otating the [RF/SQL ] 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”
    against the right edge of the analog S-meter scale.

    [RF/SQL] Knob

    QUICK POINT:
    ˆ 5eception freTuently can be optimi]ed by rotating
    the [RF/SQL] knob slightly counter-clockwise to the
    point where the “stationary” meter indication is set
    just about the same as the incoming noise level. This
    will reduce the 5F gain to ¿nd a level of improved
    signal to noise ratio.
    ˆ The 5F Gain control, along with the I32 and the $ttenuator features, all affect the system receiver gain
    in different ways. The I32 generally should be the
    ¿rst feature engaged when dealing with a high noise
    level, or a crowded, high-level signal environment.
    $lso, the I32 generally should be the first feature
    engaged, if the freTuency is low enough to allow the
    preampli¿er to be bypassed. Thereafter, the 5F Gain
    and $ttenuator features may be employed to provide
    precise, delicate adjustment of the receiver gain to
    fully optimi]e performance.

    Switching the Knob Functions
    You may switch the [RF/SQL] knob from the 5F Gain Function to the STuelch Function via 0enu item 038.

    AGC (AUTOMATIC GAIN CONTROL)
    The $GC system is designed to help compensate for fading and other propagation effects. The $GC characteristics can
    be individually set for each operating mode. The basic objective of $GC is to maintain a constant audio output level
    once a certain minimum threshold of signal strength is achieved.
    3ress the [AGC] button repeatedly to select the desired
    receiver-recovery time constant. You will observe the
    $GC status notation in the $GC column of the .ey
    Function 'isplay on the TFT display, denoting the $GC
    receiver-recovery time currently in use. For most operations, we recommend the “$UT2” mode. $dditionally,
    you may disable the $GC by pressing and holding in the
    [AGC] button for one second.

    NOTE:
    ˆ The “$UT2” selection mode selects the optimum

    ADVICE:
    ˆ If the $GC receiver-recovery time is set to “2ff” by
    pressing and holding in the [AGC] button, the Smeter will no longer deÀect. $dditionally, you will
    likely encounter distortion on stronger signals, as the
    IF ampli¿ers and the following stages are probably
    being overloaded.
    QUICK POINT:
    Several aspects of $GC performance may be con¿gured
    via the 0enu. However, because $GC can have such a
    profound impact on overall receiver performance, we
    generally do not recommend any changes to the $GC
    0enu selections until you are thoroughly familiar with
    the performance of the FTDX1200.
    TERMINOLOGY:
    $utomatic Gain Control, or $GC, is a circuit that senses
    the received signal strength, and then limits the gain of
    the 5F and IF stages to keep the output audio volume at
    a more-or-less constant level. $GC also protects the 5F,
    IF, $udio, and 'S3 stages from overload, as it limits the
    signal strength that is allowed to Àow, irrespective of the
    input signal level.

    SLOPED AGC Operation
    In traditional $GC systems, the audio output from the transceiver becomes essentially ¿xed once the threshold
    for $GC action is reached usually several do]en dB above the no-signal noise Àoor). The FTDX1200, however,
    includes an innovative Sloped $GC system on the 0ain band VF2-$) receiver, that allows the audio volume
    to rise and fall slightly according to signal strength. $lthough the risefall slope is not dramatic, it is suf¿cient to
    allow you to use your ear to discern and separate signals according to signal strength, not just audio freTuency.

    SSB/AM MODE TRANSMISSION
    ADVICE:
    ˆ $LC meter deÀection may be caused by excessive
    drive power, but also by reÀected power detected in
    the antenna system. If the impedance presented to
    the transceiver is other than 0 2hms, $LC meter action may be observed that is not related to the proper
    setting of the [MIC/SPEED] knob. Therefore, we
    recommend that you make the [MIC/SPEED] knob
    adjustments into a dummy load or antenna system
    presenting impedance very close to 0 2hms.
    ˆ In the SSB mode, you may set the desired power
    output via 0enu item “177 TX MAX POWER”. The
    adjustment range is between  Watts and 100 Watts.
    You should always use the minimum power necessary
    to maintain reliable communications.
    ˆ When performing “on air” tests such as the setup of
    microphone gain), be sure to check the freTuency before transmitting, to avoid interference to others who
    may already be using the freTuency.

    ˆ Four techniTues for exercising Transmit5eceive

    USING THE AUTOMATIC ANTENNA TUNER
    The $utomatic $ntenna Tuner hereinafter referred to as the “$TU”) built into each FTDX1200 is designed to ensure a
    0-2hm load for the ¿nal ampli¿er stage of the transmitter. We recommend that the $TU be used whenever you operate
    on the FTDX1200.
    ADVICE:
    ˆ Because the $TU of the FTDX1200 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 SW5 at the antenna feed point itself.
    When designing and building your antenna system, we recommend that every effort be made to ensure a low SW5
    at the antenna feed point.
    ˆ The $TU of the FTDX1200 includes 100 memories for tuning data. (leven of these memories are allocated, one per
    $mateur band, so that each band has at least one setting preset for use on that band. The remaining 8 memories are
    reserved for the 8 most-recent tuning points, for Tuick freTuency change without the need to retune the $TU.
    ˆ The $TU in the FTDX1200 is designed to match impedances within the range of 16. 2hms to 10 2hms, corresponding to an SW5 of 31 or less on the 160 through 6 meter amateur bands. $ccordingly, simple non-resonant
    whip antennas, along with random-length wires and the “G5V” antenna on most bands) may not be within the impedance matching range of the $TU.

    ATU OPERATION
    1. Use the 0ain Tuning 'ial knob to set the radio to
    the desired operating freTuency within the $mateur
    band.
    . 3ress the [TUNE] button momentarily to place the
    $TU in the transmit line no adjustmenttuning will
    occur yet). The “TUNER” 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 freTuency.
    3. 3ress and hold in the [TUNE] button for one second
    to begin automatic tuning. The transmitter will be engaged, and the “TUNER” icon will blink while tuning is in progress. When the optimum tuning point
    has been reached, the radio will return to receive,
    and the “TUNER” icon will again glow steadily instead of blinking).
    4. To disconnect the $TU from the transmit line, press
    the [ TUNE ] button momentarily. The “TUNER”
    icon will turn off, con¿rming that the $TU has been
    turned off. In the “2ff” mode, the transceiver will be
    directly connected to the coaxial cable connected to
    your antenna, and will respond to whatever impedance is present at the station end of the coax.
    ADVICE:
    The $TU circuit is located between the ¿nal ampli¿er
    and the rear-panel antenna jack reception is not affected
    by the $TU.

    FT DX 1200 OPERATING MANUAL

    [TUNE] Button

    QUICK POINTS:
    $s shipped from the factory, only one $TU alignment
    point is saved on each $mateur band. This was memori]ed during the ¿nal alignment and performance veri¿cation stages on the production line.
    NOTE:
    3lease check the operating freTuency before beginning
    the tuning process, to be sure you are not interfering
    with others who may already be using the freTuency.
    TERMINOLOGY:
    $ntenna Tuner 0emories The microprocessor of the
    $TU makes a note of the selected tuning capacitors and
    inductors, and stores the data for each 10 kH] window
    in which tuning has occurred. This eliminates the need
    to re-tune every time you return to a freTuency on which
    you have already completed the tuning process.

    USING THE AUTOMATIC ANTENNA TUNER
    ABOUT ATU OPERATION
    Figure 1 depicts a situation where normal tuning via the $TU has been successfully completed, and the tuning data has
    been stored in the $TU memory. The antenna system as seen by the transmitter is shown.
    In Figure , the operator has changed freTuency, and the “HI-SWR” icon has appeared. The operator presses and holds
    in the [TUNE] button for two seconds to begin impedance matching using the $TU.
    If a high SW5 condition exists above 31), corrective action must be taken in the antenna system to bring the impedance closer to 0 2hms. The $TU will refuse to memori]e settings on freTuencies where the SW5 exceeds 31. $ High
    SW5 may indicate a mechanical failure in the feed system, and can lead to the generation of spurious signals causing
    TVI, etc.

    ENHANCING TRANSMIT SIGNAL QUALITY
    PARAMETRIC MICROPHONE EQUALIZER (SSB/AM/FM MODE)
    The FTDX1200 includes a uniTue Three-Band 3arametric 0icrophone (Tuali]er that provides precise, independent control over the low, mid and treble ranges in your voice waveform. You may utili]e one group of settings when the speech
    processor is off and an alternate group of settings when the speech processor is on. The speech processor feature is described in the next chapter.
    QUICK POINT:
    The 3arametric (Tuali]er is a uniTue techniTue for adjusting the signal Tuality. The three audio ranges may be adjusted
    so precisely, it is possible to craft an audio response that provides a natural and pleasant sound that you may not have
    ever experienced before. $lternately, the effective “talk power” can be signi¿cantly enhanced.
    The aspects of con¿guration that you may adjust on the 3arametric (Tuali]er are
    Center Frequency The center freTuency of each of the three bands may be adjusted.
    Gain
    The amount of enhancement or suppression) within each band may be adjusted.

    ADJUSTING THE SSB TRANSMITTED BANDWIDTH (SSB MODE)
    For transmission on SSB, a default bandwidth of .4 kH] is provided. This bandwidth provides reasonable ¿delity along
    with good talk power, and is typical of the bandwidth used for decades for SSB transmission. The bandwidth may be
    varied by the operator, to provide different levels of ¿delity or talk power, according to your preferences.
    Here are the steps to adjust the SSB transmit bandwidth
    1. 3ress the [MENU] button to engage the 0enu.
    . 5otate the [VFO-B/CLAR] knob or press the ST
    button) to select 0enu item “104 SSB TX BPF”.
    3. 3ress the [SELECT] button, then rotate the [VFO-B/

    desired bandwidth. The available selections are 1003000 H], 100-00 H], 00-800 H], 300-700 H],
    400-600 H] and 3000 WB. The default is 300-700
    H]. $ wider bandwidth will provide greater fidelity. $ narrow bandwidth will compress the available
    transmitter power into less spectrum, resulting in
    more “talk power” for '; pile-ups.
    4. 3ress the [SELECT] button, then press the [MENU]
    button to save the new setting and exit to normal operation.
    ADVICE:
    The Transmit 0onitor function is a very helpful way to
    con¿rm the effect that changing the bandwidth will have
    on ¿delity. By 3ressing the [MONI] button, you will be
    able to hear the difference in sound Tuality as you make
    changes.

    CW CONVENIENCE FEATURES
    CW SPOTTING (ZERO-BEATING)
    “Spotting” ]eroing in on another CW station) is a handy techniTue to ensure you and the other station are precisely on
    the same freTuency.
    The Tuning 2ffset Indicator in the display may also be moved so you can adjust your receiver freTuency to center the
    incoming station on the pitch corresponding to that of your transmitted signal.

    Using the Auto Zeroing System

    [SELECT] Button

    2nly when the optional FFT unit is installed)
    3ress the [ S /T /W /X ] button to select the “ZIN/
    SPOT”. 3ress the [SELECT] switch momentarily to
    adjust the receiving freTuency to the ]ero-in automatically while receiving the CW signal.

    Using the SPOT System
    3ress the [ S /T /W /X ] button to select the “ZIN/
    SPOT”. 3ress the [MONI] button, then while pressing
    the front panel [SELECT] button, the Spot tone will be
    heard through your speaker. This tone corresponds to the
    pitch of your transmitted signal. If you adjust the receiver freTuency until the pitch of the received CW signal
    matches that of the Spot tone, your transmitted signal
    will be precisely matched to that of the other station.
    5elease the [SELECT] button to turn the Spot tone off.
    ADVICE:
    ˆ In a tough '; pile-up, you may actually want to
    use the S32T system to ¿nd a “gap” in the spread
    of calling stations, instead of ]eroing in precisely
    on the last station being worked by the '; station.
    From the '; side, if a do]en or more operators also
    using Yaesu’s S32T system) all call precisely on the
    same freTuency, their dots and dashes merge into a
    single, long tone that the '; station cannot decipher.
    In such situations, calling slightly higher or lower in
    freTuency may get your call through.
    ˆ The Tuning 2ffset Indicator in the display may be
    utili]ed for CW freTuency adjustment, as well. Its
    con¿guration is set via 0enu item “011 BAR DISPLAY SELECT” at the factory, and the Tuning 2ffset
    Indicator is already set to the “CW TUNE” selection.
    QUICK POINTS:
    ˆ The CW Spotting process utili]es the Spot tone or
    the Tuning 2ffset Indicator. The actual offset pitch
    is set by 0enu item “056 CW PITCH”. The offset
    pitch may be set to any freTuency between 300 H]
    and 100 H], in 0 H] steps. You can either match
    tones audibly using the [SELECT] button) or tune
    the receiver freTuency so that the central red marker
    on the Tuning 2ffset indicator lights up. 1ote that
    there are 31 “dots” on the Tuning 2ffset Indicator,
    and depending on the resolution selected, the incoming CW signal may fall outside the visible range of
    the bar indicator, if you are not reasonably close to
    the proper alignment of tones.

    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).
    . 1ow be sure your mode selection is still set for VF2$, and then press and hold in the [MODE] button for
    one second. The “LSB” and “CW” will appear in the
    display, indicating that the “LSB” injection side has
    now been selected.
    3. To return to the normal USB) injection side and
    cancel CW 5everse operation, press and hold in the
    [ MODE ] button for one second. the “USB” and
    “CW” will appear in the display).
    NOTES:
    ˆ When CW 5everse is engaged, the action of the Tuning 2ffset Indicator will also be reversed
    ˆ When the incoming signal pitch tone is properly
    aligned, the central red marker lights up whether or
    not CW 5everse is engaged.

    [MODE] Button

    In the illustration, Figure “A” demonstrates the
    normal CW injection setup, using the USB side.
    In Figure “B”, CW 5everse has been engaged to
    receive using LSB-side injection and eliminate
    interference.
    The bene¿cial effect of switching sidebands can
    be clearly seen in this example.
