Connecting AC Power There are two power switches on this transceiver, one each on the rear and front panels. If the rear panel's Power switch is not turned on, the front panel Power switch will not function. Push the rear panel's Power switch to the [I] position to apply power from the power supply to the OCXO (Reference Crystal Oven) and to enable the front panel power switch. Press and hold in the front panel Power switch for two seconds to turn the transceiver on. NOTE The self-check function of the CPU inside the radio will begin. Then, if the optional RF -Tuning Unit is installed, the -Tuning circuitry will receive the data from the CPU and it will perform its own self-check, and will preset itself to the proper settings for the current operating frequency. While the -Tuning circuitry is obtaining the data, the drive mechanism will move from one end of its range to the other end (fast), and this will cause a temporary "motor" noise that can be heard; this, does not represent any trouble or problem. When the optional -Tuning Unit and/or the Data Management Unit are installed, the initialization process for the transceiver will take about 10 seconds, after which operation may begin. 2. Configuring Your FT DX 9000 Contest Using the Menu The FT DX 9000 Contest is configured, at the factory, with its various functions set up in a manner typical for most operation. Via the "Menu" system, you may change these settings to match the way you want your transceiver to operate. Menu programming is enabled by pressing the [MNU] (Menu) key momentarily. You may then rotate the [Main Tuning Dial] knob to display the desired Menu item, in the menu list, on the LCD. Each of the settings can be changed or customized via the [CLAR/VFO-B] knob, as you like, in this mode. Once you have made a change to the configuration of a Menu item or items, you must press and hold in the [MNU] (Menu) key for two seconds to save the new settings and exit to normal operation. If you wish to cancel a change to a Menu item or items, just press the [MNU] key momentarily. If you do not press and hold in the [MNU] key in for two seconds, any changes you have made will not be saved. [Main Tuning Dial] Knob [MNU] Key [CLAR/VFO-B] Knob MENU ITEM MENU SETTING Page 4 FT DX 9000 CONTEST OPERATION MANUAL YOU BEGIN BEFORE YOU BEGIN . . . 3. Connecting and Selecting the Microphone The FT DX 9000 Contest comes equipped with two microphone connectors: the front panel includes a "Cannon" (XLR) three-pin connector, while the rear panel provides an eight-pin (round) connector. As shipped from the factory, the front panel XLR connector is engaged for operation, and the rear panel 8-pin microphone jack is not connected. If you wish to enable the 8-pin connector instead of the XLR connector, use the Menu to accomplish this. Note that you may leave microphones connected to both jacks, and may select the microphone you want for operation on a particular operating mode (SSB, AM, FM, etc.), as well! Press the [MNU] (Menu) key momentarily to enter the Menu Mode. Rotate the [Main Tuning Dial] knob to select Menu Item #077, located within the "MODE SSB" group: SSB MIC SELECT. Rotate the [CLAR/VFO-B] knob to change the setting of Menu #077 from "FRONT" to "REAR." Press and hold in the [MNU] (Menu) key for two seconds to save the new setting and exit to normal operation. In a similar manner, you may use Menu #048 (AM MIC SELECT) in the MODE-AM Menu Group to select the microphone jack to be used during AM operation, and Menu #067 (FM MIC SELECT) in the MODE-FM Menu Group to select the microphone to be used during FM transmission.

Extending the Front Feet In order to elevate the front panel for easy viewing, the front left and right feet of the bottom case may be extended. Pull the front legs outward from the bottom panel. Rotate the legs counter-clockwise to lock them in the extended position. Be sure the legs have locked securely in place, because the transceiver is quite heavy and an unlocked leg could result in damage, should the transceiver move suddenly. EXTEND Retracting the Front Feet Rotate the legs clockwise, and push them inward while rotating to the right. The front feel should now be locked in the retracted position. RETRACT FT DX 9000 CONTEST OPERATION MANUAL Page 5 YOU BEGIN BEFORE YOU BEGIN . . . 5. Adjusting the Main Dial Torque The torque (drag) of the Main Tuning Dial may be adjusted according to your preferences. Simply hold down the rear skirt of the knob, and while holding it in place rotate the Main Dial itself to the right to reduce the drag, or to the left to increase the drag. HOLD THE SKIRT TIGHTEN TOOSEN 6. Restarting Power after a Voltage Fluctuation If your AC mains power should suffer a significant fluctuation or interruption, we recommend that you go through a complete power-up cycle, in order to ensure that all circuits are properly initialized. To do this, be sure the front panel Power switch is turned off, then set the rear-panel Power switch to the "O" O position. Now unplug the AC cable from the rear panel of the transceiver, and wait ten seconds. Plug the AC cable back in, set the rear-panel Power switch to "O," and now press and hold in the frontO panel Power switch for two seconds to turn the transceiver on. After about 50 seconds, all circuits will be initialized, and normal operation may resume. Page 6 FT DX 9000 CONTEST OPERATION MANUAL YOU BEGIN BEFORE YOU BEGIN . . . 7.

Once the transceiver comes on, you may release the other two switches. [POWER] Switch [FAST] Switch & [LOCK] Switch FT DX 9000 CONTEST OPERATION MANUAL Page 7 EATURES FEATURES Superior Visibility and Logical, Fatigue-reducing Panel Layout The front panel layout is logically crafted, with the large-aperture main frequency display squarely in the middle of the front panel; the two large S-meters to the left providing instant recognition of signal strength. Just as in an aircraft cockpit, the panel meters and the LCD are canted slightly toward the center for maximum visibility. Large, Multi-colored VFD Fluorescent Display A proprietary, high-brightness VFD (fluorescent) display is incorporated in the FT DX 9000 Contest, providing outstanding visibility and easy reading of the important frequency information, whether in dim or bright lighting environments. Function-Indicating LEDs The many function status indications on the front panel are clearly identified by the operator, thanks to the innovative multi-color LEDs incorporated in design. A Red LED indicates that a function is engaged on the VFO-A, while an Orange LED shows that the function is engaged on the VFO-B. Indirect Illumination To assist with operation in a dark environment, indirect illumination of the front panel's knobs and switches is provided via lamps installed beneath the meters and the [BAND] switch. Aluminum-Die-Cast Oversized Main Tuning Dial The Main Tuning Dial is a large-diameter (3.2"/81 mm) dial directly coupled to the magnetic rotary encoder which drives the HRDDS via microprocessor control. Its heavy weight (7 oz./200 g) and quality mounting and construction provide a smooth "flywheel" effect during operation, ideal for quick cruising up and down a band. Oversized Knobs for Most Important Functions The concentric AF/RF Gain, SHIFT/WIDTH, and CLAR/VFO-B knobs are conveniently located at the right-bottom side of the Front Panel, for ease of access to these important controls. World's First 400 MHz HRDDS Local Oscillator So as to optimize spurious-free dynamic range in a multi-signal environment, Yaesu's engineers have introduced the world's first HRDDS (High Resolution Direct Digital Synthesizer) as the first local oscillator of the FT DX 9000 Contest. Dividing directly from this high frequency, this local oscillator design ensures extraordinarily low noise, resulting in improved weak-signal reception even on a crowded band during a weekend contest. New-design Large-area OCXO Reference Oscillator Serving as the master reference oscillator for the transceiver, the 10 MHz OCXO (Oven Controlled Crystal Oscillator) is a large-area (50 x 50 mm/2" x 2") oven-stabilized oscillator operating at high temperature, for industry-leading frequency stability rated at 0.03 ppm over the temperature range ­10 °C to +60 °C (­14 °F to +140 °F). Triple-conversion Design with Optimized Gain Distribution Taking into account the most efficient transceiver design concept consistent with high performance we have adopted a triple-conversion IF structure, utilizing a first IF at 40 MHz, a second IF at 455 kHz, and the third IF at 30 kHz (for FM, the 3rd IF is at 24 kHz). Gain distribution through all stages is carefully optimized, for preservation of high system dynamic range. Ultra-strong Receiver Front End YAESU's outstanding RF-stage filtering establishes a clean performance that allows the rest of the receiver to perform at a high level. By reducing the ingress of energy from very strong sources like Shortwave Broadcast, local AM/FM/TV stations, and other signal sources, the overall purity of the spectrum delivered to the RF Amplifier first mixer, and subsequent stages is maintained, and the system Blocking Dynamic Range is also enhanced. Professional-Grade Cannon (XLR) Microphone Connector The FT DX 9000 Contest incorporates, for the first time ever in an Amateur Radio transceiver, a balanced-input "Cannon" (XLR) microphone connector on the front panel, for use with studio-grade professional microphones. A round 8-pin microphone jack is also provided on the rear panel. Two High-precision Analog Meters (Page 27) The FT DX 9000 Contest incorporates two large (3.4"/86 mm) high-precision analog meters, for the utmost accuracy in measuring transceiver performance. Visibility is enhanced by the oversized meter scales, making the meters easy to read at all times. Separated Clarifier Display (Pages 43, 89) A clearly-separated display window within the main frequency display area contains receiver and/or transmitter frequency offset ("Clarifier") data, for quick comprehension by the operator. YAESU Custom-designed 32-Bit Floating Point IF DSP (Page 54) The new IF DSP system, utilizing a TI TMS320C6711 device, is a high-speed 32-bit floating point circuit designed with a unique objective: to do away with the "digital" sound of many DSP filtering systems, and emulate the "Analog Sound" so familiar and comfortable to HF DX and Contest operators. The result is a leading-edge receiver that has the "feel" of a traditional analog receiver, but with the flexibility and superb filtering capability of a modern digital filtering system. Page 8 FT DX 9000 CONTEST OPERATION MANUAL EATURES FEATURES VRF (Variable RF Filter) Preselector Filter (Page 58) Yaesu's robust VRF (Variable RF Filter) preselector provides a relay-selected RF selectivity much tighter than that afforded by traditional bandpass filter networks. Sealed relays select heavy-duty inductors and capacitors, providing a tracking RF filter that protects the RF amplifier and following stages from strong out-of-band energy. First IF 3 kHz Roofing Filter (Page 24, 59) In the 40 MHz 1st IF, three selectable roofing filters are provided, in bandwidths of 3 kHz, 6 kHz, and 15 kHz, to protect the following stages from strong signals that could degrade dynamic range in the first IF amplifier and subsequent stages. The roofing filters are automatically assigned according to the operating mode, but the operator may override the automatic selections on the fly. CONTOUR Filter Enhances "Analog Feeling" of DSP Filters (Page 29, 60) The DSP-based Contour system is a unique five-band filter that may be used to roll off or peak the IF response. It is chiefly useful for modifying the response of the ultra-sharp DSP filters, allowing you to roll off (or emphasize) certain frequency components. Often times, the result is that a difficult-to-understand signal suddenly will pop out of the background noise as solid copy. SLOPED AGC Circuitry (Page 70) In traditional AGC systems, all signals rising above a certain RF level are then clamped together at the same audio output, so as to prevent distortion throughout the IF and AF stages. In the FT DX 9000 Contest, however, you can engage the "Sloped" AGC capability to provide an AGC response whereby ever-increasing signal strength results in a slightly-louder audio response, still without accompanying distortion. This lets you use your brain to sort out weak signals from strong ones more effectively. Receiver AF Limiter Circuit (Page 30, 71) Occasionally a noise burst or a sudden transmission from a loud station may startle you if you have the AF Gain turned up, and may even damage your hearing temporarily. The FT DX 9000 Contest provides an AF Limiter (AFL) circuit which, once engaged, clamps an upper limit on the available audio output power, much like the AGC circuit does in the RF and IF stages. Parametric Microphone Equalizer Circuit (Page 82) For unmatched flexibility in tailoring your microphone's audio to match your voice, Yaesu's engineers have incorporated the industry's first Three-Band Parametric Microphone Equalizer, which allows you to enhance or suppress frequency components in three different audio bands. Equalization may be applied independently to microphones attached to the front and rear panel microphone jacks. Ultra-linear Class-A Operation Capability (Page 84) The FT DX 9000 Contest's Class-A capability provides ultra-linear amplifier operation at 75 Watts of power output. Typically, 3rdorder IMD products are suppressed more than 50 dB, while 5th- and higher-order distortion products are at least 70 dB down during Class-A operation. Rugged, High-Output Final Amplifier Design (Page 85) The final amplifier stage of the FT DX 9000 Contest utilizes push-pull SD2931 MOS FET devices in a conservative, high-stability design. The large-area die-cast aluminum heat sink is monitored thermostatically, and a quiet cooling fan will engage when the heat sink temperature rises during long periods of high-power transmission. Customization of Your FT DX 9000 Contest A wide range of custom configuration options (other than a better location or taller tower!) are available for your FT DX 9000 Contest, allowing you to build a Dream Station from the basic "Contest" version foundation. Because these options involve high-technology modules, please consult WDXC regarding factory installation of these items. Dual Receive Unit (RXU-9000) The Dual Receive Unit (model RXU-9000) not only permits simultaneous reception on two frequencies (in the same band or on different bands), but also it enables Full Duplex operation, whereby you may be transmitting on 20 meters while, simultaneously, receiving on 40 meters or any band other than 14 MHz. The RXU-9000 is a fully-equipped replica of the VFO-A receiver, so reception is not compromised when using the VFO-B. RF -Tuning Units (MTU-160, MTU-80/40, MTU-30/20) On the 14 MHz and lower bands, the -Tuning Units provide extraordinarily high Q; the resulting steep shape factor is a powerful aid for reducing off-frequency interference. Separate modules are available for the 1.8 MHz, 3.5/7 MHz, and 10.1/14 MHz bands, and they may be installed on the Main Receiver only (not in the RXU-9000). Thanks to the large (1.1"/28 mm) inductor through which a stack of ferrite cores is adjusted, the narrow RF bandwidth of the Tuning system provides unmatched protection for the receiver front end and following circuits. Variable RF Preselector Unit (VRF-9000) The VRF-9000 provides outstanding protection against out-of-band interference, with a bandwidth much narrower than the standard fixed bandpass filter network. Adding the VRF-9000 can be particularly useful if your station is located near a broadcast station, or if you use Dual Receive a lot in a multi-transmitter environment. Data Management Unit (DMU-9000)/TFT Display Unit (TFT-9000) In order to enable the World Clock, Spectrum Scope, Audio Scope/Oscilloscope, Logbook, Rotator Control, and Temperature/SWR Status Display functions, you may install the Data Management Unit (DMU-9000), which actually is a mini-computer that fits inside your transceiver. These various functions may then be displayed on a user-supplied external display screen, such as a plasma or TFT display. Furthermore, if the TFT Display Unit (TFT-9000) is installed, an external display becomes unnecessary. The TFT-9000 includes a 6.5", 800 x 4.80 dot screen which provides high resolution and easy viewing, as well as quick access to the control options available on each TFT display page.

While minor excursions from the 50-Ohm specification are of no consequence, the transceiver's Automatic Antenna Tuner may not be able to reduce the impedance mismatch to an acceptable value if the Standing Wave Ratio (SWR) present at the Antenna jack is greater than 3:1. Every effort should, therefore, be made to ensure that the impedance of the antenna system utilized with the FT DX 9000 Contest be as close as possible to the specified 50-Ohm value. Any antenna to be used with the FT DX 9000 Contest 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 so as to ensure proper antenna performance. The same precautions apply to any additional (receive-only) antennas connected to the RX ANT jack; if your receive-only antennas do not have an impedance near 50 Ohms at the operating frequency, you may need to install an external antenna tuner to obtain optimum performance. ABOUT COAXIAL CABLE Use high-quality 50-Ohm coaxial cable for the lead-in to your FT DX 9000 Contest 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 connectors, except for the RX OUT BNC connectors used for special filters, etc. 1/16" Adapter 3/4" 1 1/8" 3/4'' 1/8'' 3/8'' 5/8'' Typical PL-259 Installation Page 12 FT DX 9000 CONTEST OPERATION MANUAL NSTALLA ALLATION NTERCONNECTIONS NTER INSTALLATION AND IINTERCONNECTIONS GROUNDING The FT DX 9000 Contest HF 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 make 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 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 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.

Ground Rod ADVICE 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. Ensure adequate ventilation around this apparatus, so as to prevent heat build-up and possible reduction 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 entertainment devices. Ensure that the AC 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 AC input jack. 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.

Besides the built-in Electronic Keyer, two key jacks are provided, one each on the front and rear panels, for convenient connection to keying devices. The Menu system allows you to configure 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 Menu item "050" for paddle input, while connecting the rear panel's KEY jack to the keying line from your personal computer (which emulates a "straight key" for connection purposes), and configure the rear panel jack using Menu item "052." Both KEY jacks on the FT DX 9000 Contest utilize "Positive" keying voltage. Key-up voltage is approximately +5V DC, and key-down current is approximately 1 mA. 2 DOT DASH DOT DASH COMMON COMMON ADVICE When connecting a key or other device to the KEY jacks, use only a 3-pin ("stereo") 1/4" phone plug; a 2-pin plug will place a short between the ring and (grounded) shaft of the plug, resulting in a constant "key-down" condition in some circumstances.

It must be in the undepressed position for reception. This switch replicates the action of the Push to Talk (PTT) switch on the microphone. When engaging the [MOX] switch, or otherwise causing a transmission to be started, be certain you have either an antenna or 50-Ohm dummy load connected to the selected Antenna jack. PHONES Jack A 1/4-inch, 3-contact jack accepts either monaural or stereo headphones with 2- or 3-contact plugs. When a plug is inserted, the loudspeaker is disabled. With stereo headphones such as the optional YH-77STA, you can monitor both VFO-A and VFO-B receiver channels at the same time during Dual Receive operation. NOTE When wearing headphones, we recommend that you turn the AF Gain levels down to their lowest settings before turning power on, to minimize the impact on your hearing caused by audio "pops" during switchon. VOX Switch VOX Operation: This button enables automatic voiceactuated transmitter switching in the SSB, AM, and FM modes. While activated, the LED inside this button glows red. The controls affecting VOX operation are the front panel's [VOX] and [DELAY] knobs (see section below). By proper adjustment of these controls, hands-free voice-actuated operation is possible. POWER Switch Press and hold in this switch for two seconds to turn the transceiver on, after first setting the rear panel Power switch to the "I" position. Press and hold in this switch for two seconds, similarly, to turn the transceiver off. If the rear panel's Power switch is set to the "O" position, the front panel [POWER] switch will not function. ADVICE This is the actual power On/Off switch for turning on the transceiver. When the rear panel's Power switch is set to the "I" position, power is supplied to the OCXO to stabilize the reference oscillator, and the remainder of the transceiver is set in a "stand-by" mode, awaiting the command for the transceiver to switch on via the front panel [POWER] switch. For further information on the rear panel Power switch, please see the discussion on page 34. DIM Switch Press this button to lower the illumination intensity of the analog meters, the frequency display, and the LCD. Press it once more to restore full brightness. ADVICE Menu Items "DISPLAY 014 DIMMER-METER" and "DISPLAY 015 DIMMER-VFD" allow you to configure the dimming levels for the analog meters and the frequency display/LCD independently, so you can customize the brightness levels. Page 20 FT DX 9000 CONTEST OPERATION MANUAL PANEL CONTR ONTROLS FRONT PANEL CONTROLS KEY Jack This 1/4-inch, 3-contact jack accepts a CW key or keyer paddles (for the built-in electronic keyer), or output from an external electronic keyer. Pinout is shown on page 19. Key up voltage is 5 V, and key down current is 1 mA. This jack may be configured for keyer, "Bug," "straight key," or computer keying interface operation via Menu Selection "MODE-CW 049 F-KEYER TYPE" (see page 137). There is another jack with the same name on the rear panel, and it may be configured independently for Internal Keyer or pseudo-straight-key operation. NOTE You cannot use a 2-contact plug in this jack (to do so produces a constant "key down" condition). ANTENNA SELECT Switches These momentary buttons select the antenna jack on the rear panel, with the selection indicated by the LED in each button. When an antenna has been selected for operation on the VFO-A, the LED in the button glows red. When an antenna has been selected for operation on the VFO-B, the LED in the button glows umber. TUNE Switch This is the on/off switch for the FT DX 9000 Contest's Automatic Antenna Tuner. Pressing this button momentarily places the antenna tuner in line between the transmitter final amplifier and the antenna jack (the LED will become illuminated). Reception is not affected. Pressing and holding in this button for 1/2 second, while receiving in an amateur band, activates the transmitter for a few seconds while the automatic antenna tuner rematches the antenna system impedance for minimum SWR. The resulting setting is automatically stored in one of the antenna tuner's 100 memories, for instant automatic recall later when the receiver is tuned near the same frequency. Pressing this button momentarily, while the Tuner is engaged, will take the Automatic Antenna tuner out of the transmit line. NOTE When the Automatic Antenna tuner is tuning itself, a signal is being transmitted. Therefore, be absolutely certain that an antenna or dummy load is connected to the selected antenna jack before pressing and holding in the [TUNE] button to start antenna tuning. Cannon ("XLR") Microphone Connector This Cannon-type (XLR) connector accepts input from the Microphone or other XLR-equipped microphone system. MIC connector pinout is shown on page 19. Proper microphone input impedance is 500 ~ 600 Ohms. If you are using a condenser microphone requiring 48 Volts DC, you may enable this voltage to appear on the microphone line; see page 74. When the 48volt supply line has been enabled, the LED adjacent to the MIC jack will glow red. To disconnect the microphone plug, draw out the microphone plug while pressing and holding in the silver push-button. IPO (INTERCEPT POINT OPTIMIZATION) Switch The [IPO(A)] Lamp-button may be used to set the optimum receiver front end characteristics of the VFO-A circuit for a very strong-signal environment. Selecting IPO bypasses the front end RF amplifier and feeds the received signals directly to the first mixer of the VFO-A receiver circuit. While the IPO feature is activated, this button will remain illuminated. The [IPO(B)] Lamp-button, similarly, allows direct feed of the received signals to the first mixer of the VFO-B circuit. While the IPO feature is activated on the VFO-B, this button will be lit. ADVICE The FT DX 9000 Contest's first mixer is an active type, using four SST310 Junction FETs. This mixer design provides gain to the receiver chain, so the noise figure of the receiver is fundamentally lower than with some other designs. Therefore, it frequently is not necessary to utilize the RF preamplifier, and the receiver Intercept Point will be substantially increased by engaging IPO, so as to feed the incoming signals directly to the first (active) mixer. We recommend that IPO be switched on whenever possible. METER Switch This control switch determines the function of the Main Meter during transmission. COMP: Indicates the RF speech compressor level (SSB modes only). PO: Indicates the power output level. SWR: Indicates the Standing Wave Ratio (Forward: Reflected). IDD: Indicates the final amplifier drain current. MIC LVL: Indicates the relative microphone level. MONI (Monitor) Switch This button enables the transmit monitor in all modes. While activated, the LED in this button glows red. Adjustment of the Monitor level is accomplished using the [MONI] knob, located just to the right of the [MONI] switch. ADVICE When using headphones, the Monitor is highly useful for making adjustments to the Parametric Equalizer or other voice quality adjustments, because the voice quality heard in the headphones is such a "natural" reproduction of the transmitted audio quality. FT DX 9000 CONTEST OPERATION MANUAL Page 21 PANEL CONTR ONTROLS FRONT PANEL CONTROLS AGC ATT Knobs MIC PROC Knobs AGC Knobs This switch selects the AGC characteristics for the VFO-A. ATT Knobs This switch selects the degree of attenuation, if any, to be applied to the VFO-A. ADVICE The Attenuator may be used in conjunction with the [IPO] switch (# , described previously) to provide two stages of signal reduction when an extremely strong signal is being received. MONI PITCH Knobs MONI Knob The inner [MONI] knob adjusts the audio level of the transmit monitor during transmission (relative to the [AF GAIN] control: # , described later), when activated by the [MONI] button (# , described previously). PITCH Knob The outer [PITCH] knob selects your preferred CW tone pitch (from 300 ~ 1000 Hz, in 50 Hz increments). The Tx sidetone, receiver IF passband, and display offset from the BFO (carrier) frequency are all affected simultaneously. The Pitch control setting also affects the operation of the CW Tuning Indicator, as the center frequency of the CW Tuning Indicator will follow the setting of this control. ADVICE The VFO-B frequency display will show the Spot tone frequency for 3 seconds whenever the outer [PITCH] knob is turned. You may disable this feature (displaying the Spot tone frequency) via Menu item "DISPLAY 022 LEVEL INDICATOR" See page 133 for details. MIC Knob The inner [MIC] knob adjusts the microphone input level for (non-processed) SSB transmission. ADVICE If you adjust the MIC Gain while speaking in a louder-than-normal voice level and watching the ALC level on the right-side meter, adjust the MIC Gain so that the ALC reaches over to the right edge of the ALC scale. Then, when you speak in a more normal voice level, you'll be certain not to be overdriving the mic amplifier stage. The VFO-B frequency display will show the microphone gain level for 3 seconds whenever the inner [MIC] knob is turned. You may disable this feature (displaying the microphone gain level) via Menu item "DISPLAY 022 LEVEL INDICATOR." See page 133 for details. PROC Knob The outer [PROC] knob sets the compression (input) level of the transmitter RF speech processor in the SSB and AM modes, when activated by the button with the same name (see next section). ADVICE The VFO-B frequency display will show the relative speech processor gain level for 3 seconds whenever the inner [MIC] knob is turned. You may disable this feature (displaying the relative speech processor gain level) via Menu item "DISPLAY 022 LEVEL INDICATOR." See page 133 for details. Page 22 FT DX 9000 CONTEST OPERATION MANUAL PANEL CONTR ONTROLS FRONT PANEL CONTROLS PROC (Processor) Switch This button enables the RF speech processor for SSB transmission. Processing level is set by the outer control with the same name (see previous section). While activated, the LED in this button glows red. ADVICE The Speech Processor is a tool for increasing the average power output through a compression technique. However, if the PROC level control is advanced too far, the increase in compression becomes counter-productive, as intelligibility will suffer. We recommend that you monitor the sound of your signal using the Monitor (with headphones), then advance the PROC level only as far as required to obtain a useful increase in average power output. When the optional Data Management Unit (DMU9000) and TFT Display Unit (TFT-9000) are installed, you may use the Audio Scope/Oscilloscope page on the TFT to help you adjust the setting of the Compression Level of the Speech Processor for the optimum performance using your voice and microphone. ADVICE The VFO-B frequency display will show the keying speed for 3 seconds whenever the inner [SPEED] knob is turned. You may disable this feature (displaying the keying speed) via Menu item "DISPLAY 022 LEVEL INDICATOR." See page 133 for details. CW DELAY Knob This outer [CW DELAY] knob sets the hang time of the CW "VOX" circuit, between the moment you stop sending, and the automatic switch from transmit back to receive during "Semi-break-in" operation. Adjust this just long enough to prevent the receiver from being restored during word spaces at your preferred sending speed. Clockwise rotation increases the hang time. ADVICE The VFO-B frequency display will show the hang time of the CW "VOX" circuit for 3 seconds whenever the outer [CW DELAY] knob is turned. You may disable this feature (displaying the hang time of the CW "VOX" circuit) via Menu item "DISPLAY 022 LEVEL INDICATOR." See page 133 for details. NOTE The SSB VOX hang time is adjusted via the [DELAY] control (# , described previously). VOX DELAY Knobs VOX Knob The inner [VOX] knob sets the gain of the VOX circuit, to set the level of microphone audio needed to activate the transmitter during voice operation while the [VOX] switch (# , described previously) is engaged. The [VOX] switch must be switched On to engage the VOX circuit. DELAY Knob The outer [DELAY] knob sets the hang time of the VOX circuit, between the moment you stop speaking, and the automatic switch from transmit back to receive. Adjust this for smooth VOX operation, so the receiver is only activated when your transmission is ended and you wish to receive. For CW operation, you can adjust the keying delay separately; see control # below. ADVICE The VFO-B frequency display will show the hang time of the VOX circuit for 3 seconds whenever the inner [DELAY] knob is turned. You may disable this feature (displaying the hang time of the VOX circuit) via Menu item "DISPLAY 022 LEVEL INDICATOR." See page 133 for details. BK-IN/SPOT Switche This button turns the full break-in (QSK) CW capability on and off. While QSK is activated, the LED in this button glows red. The [SPOT] button turns on the CW receiver spotting tone; by matching the SPOT tone to that of the incoming CW signal (precisely the same pitch), you will be "zero beating" your transmitted signal on to the frequency of the other station. ADVICE The VFO-B frequency display shows the spotting tone frequency when this switch is pressed. NB/SQL Knobs NB Knob The inner [NB] knob adjusts the noise blanking level when the (analog) IF noise blanker is activated by pressing the [NB] switch (# below). The Noise Blanker is activated via the [NB] switch, described in the next section. SQL Knob The outer [SQL] knob sets the signal level threshold at which VFO-A audio is muted, in all modes. It is very useful during local rag-chews, to eliminate noise between incoming transmissions. This control is normally kept fully counter-clockwise (off), except when scanning and during FM operation. KEYER Switch This button toggles the internal CW keyer on and off. While activated, the LED in this button glows red. The Keyer sending speed, and the CW Hang Time are adjusted via the controls described in the next section. SPEED CW DELAY Knobs NB Switch Pressing this button activates the (analog) IF Noise Blanker, which may help reduce many different types of man-made impulse noise (but not atmospherics). When the Noise Blanker is activated, the LED inside the button will glow red. Adjustment of the Noise Blanker level is accomplished via the [NB] knob (# above), described in the previous section. The internal Electronic Keyer is activated by the [KEYER] switch, described in the previous section. SPEED Knob The inner [SPEED] knob adjusts the keying speed of the internal CW keyer. Clockwise rotation increases the sending speed. FT DX 9000 CONTEST OPERATION MANUAL Page 23 PANEL CONTR ONTROLS FRONT PANEL CONTROLS KEY Jack This 1/4-inch, 3-contact jack accepts a CW key or keyer paddles (for the built-in electronic keyer), or output from an external electronic keyer. Pinout is shown on page 19. Key up voltage is 5 V, and key down current is 1 mA. This jack may be configured for keyer, "Bug," "straight key," or computer keying interface operation via Menu item "MODE-CW 049 F-KEYER TYPE" (see page 137). There is another jack with the same name on the rear panel, and it may be configured independently for Internal Keyer or pseudo-straight-key operation. NOTE This Key jack is connected in parallel with the jack with the same name on the front panel. You cannot use a 2-contact plug in this jack (to do so produces a constant "key down" condition). ROOFING Switch This button selects the bandwidth for the VFO-A receiver's first IF Roofing Filter. Available selections are 3 kHz, 6 kHz, 15 kHz, or Auto, and the LED indicator will change according to the bandwidth selected. ADVICE Because the roofing filter is in the first IF, the protection it provides against interference is quite significant. When set to AUTO, the SSB bandwidth is 6 kHz, while CW is 3 kHz and FM/RTTY are 15 kHz. On a crowded SSB band, however, you may wish to select the 3 kHz filter, for the maximum possible interference rejection. D.NOTCH Switch This button turns the VFO-A Digital Notch Filter on and off. When the Digital Notch Filter is activated, the LED indicator will glow red. This is an automatic circuit, and there is no adjustment knob for the D.NOTCH. PHONES Jack A 1/4-inch, 3-contact jack accepts either monaural or stereo headphones with 2- or 3-contact plugs. When a plug is inserted, the loudspeaker is disabled. With stereo headphones such as the optional YH-77STA, you can monitor both VFO-A and VFO-B channels at the same time during Dual Receive operation. NOTE This Phones jack is connected in parallel with the jack with the same name on the front panel. When wearing headphones, we recommend that you turn the AF Gain levels down to their lowest settings before turning power on, to minimize the impact on your hearing caused by audio "pops" during switchon. MODE Switches A, B Button Pressing the [A] or [B] switch will illuminate the respective indicator imbedded within the switch, allowing adjustment of the operating mode on the VFO-A or VFO-B. Pressing the [A] switch causes the indicator to glow Red, signifying VFO-A is being adjusted. Similarly, pressing the [B] switch will cause its indicator to glow Orange, signifying VFO-B adjustment. ADVICE When changing bands, be sure to press the [A] or [B] switch first, then press the appropriate Band selector switch, so as to change operating frequencies on the proper (VFO-A or VFO-B).

Also, when you press and hold in the [PKT] button for one second, the user-programmed custom function setting mode will be activated. RX Indicator/Switch This is the switch that the VFO-A On and Off. When the VFO-A is activated, the Green LED imbedded within the switch will light up. TX Indicator/Switch When this button is pushed, the indicator will glow Red, and the transmitter will be engaged on the same frequency and mode as was set up for the VFO-A (subject to any Clarifier offset, of course). ADVICE If this indicator is not illuminated, it means that the VFO-B TX indicator has been selected (it will be glowing Red). In this case, transmission will be effected on the frequency and mode programmed for the VFO-B. QMB (Quick Memory Bank) Switch STO (Store) Button Pressing this button copies operating information (frequency, mode, bandwidth, and also repeater direction/ shift frequency and CTCSS functions on the FM mode) into consecutive QMB Memories. RCL (Recall) Button Pressing this button recalls one of up to five Quick Memory Bank memories for operation. Main Tuning Dial Knob This large knob adjusts the operating frequency of the VFO-A or a recalled memory. Clockwise rotation of this knob increases the frequency. Default tuning increments are 10 Hz (100 Hz in AM and FM modes); when the [FAST] switch is pressed, the tuning steps increase. The available steps are: Operating Mode 1 Step* 1 Dial Rotation LSB/USB/CW/RTTY/PKT(LSB) 10 Hz (100 Hz) 10 kHz (100 kHz) AM/FM/PKT(FM) 100 Hz (1 kHz) 100 kHz (1 MHz) *Numbers in parentheses indicate steps when the [FAST] switch is On. NAR (Narrow) Switch In the SSB/CW mode, this button is used to set the bandwidth of the DSP IF filters to a user-programmed bandwidth (default values are SSB: 1.8 kHz, CW/ RTTY/PSK: 300 Hz, AM: 6 kHz). When [NAR] has been engaged, the [WIDTH] knob will be disabled. In the AM mode, this button is used to toggle the receiver's bandwidth between wide (9 kHz) and narrow (6 kHz). In the FM mode on the 28 MHz and 50 MHz bands, this button is used to toggle the FM deviation/bandwidth between wide (± 5.0 kHz Dev./25.0 kHz BW) and narrow (± 2.5 kHz Dev./12.5 kHz BW). Pressing the [A] or [B] button (located above the MODE selection buttons) will select either the VFOA or VFO-B for individual bandwidth setting. ADVICE When [NAR] has been engaged, the [WIDTH] knob will be disabled, although IF Shift still works normally. ADVICE The tuning steps for the [Main Tuning Dial] knob (described in this section) are set, at the factory, to 10 Hz per step. Via Menu item "TUNING 139 DIAL STEP," however, you may change this setting from 10 Hz to 5 Hz or 1 Hz instead. When press the [FAST] button (# below), the tuning step change to 100 Hz. FAST Switch Pressing this button will increase or decrease the tuning rate of the [Main Tuning Dial] knob (# above) by a factor of ten, as mentioned in the previous section. When this function is activated, the LED inside the button will glow red. SPLIT Switch Pressing this button to activates split frequency operation between the VFO-A, used for transmission and VFO-B, used for reception. The same name LED located at the right of the main tuning knob glows orange while this function is active. If you press and hold in the [SPLIT] switch for two seconds, the "Quick Split" feature will be engaged, whereby the VFO-B will automatically be set to a frequency 5 kHz higher than the VFO-A frequency, and the transceiver will be placed in the Split mode.
