Page 53FT-2000D OPERATING MANUALThe FT-2000D includes an unmatched array of RF selectivity-enhancing features. Please study the material below care-fully, so as to understand the various features completely.USING THE VRF (VARIABLE RF FRONT-END FILTER)The VRF system is a high-performance RF front-end preselector that has high Q factor and low insertion loss. VRF pro-vides outstanding rejection of out-of-band signals, and can significantly improve reception in tough co-location operationssuch as a contest or DX-pedition. The FT-2000D’s VRF system affects the 1.8 - 28 MHz amateur bands only.ADVANCED INTERFERENCE-SUPPRESSION FEATURES: RF FRONT END1. Press the [VRF] button momentarily. The “ ” iconwill appear at the FLT column of the Receiver Con-figuration Indicator on the display, and the VRF sys-tem will beengaged,centered onyour current Amateur band.2. You may rotate the [VRF] knob to skew the positionof the VRF system relative to your operating frequency.Because the VRF system is relatively broad, althoughstill much narrower than the fixed bandpass filter), youmay not hear much difference in the background noiseor signal quality when you make minor adjustments.However, if you have receiving problems associatedby a very strong signal, rotation of the [VRF] knobmay help reduce the strength of the interfering station,allowing improved reception of the desired signal ifoverload was degrading reception.ADVICE:You may observe therelative skew of theVRF system in the Tun-ing Offset Indicator onthe display while turningthe [VRF] knob.After moving the passband of the VRF systemmanually, you may re-center it on the current Ama-teur band by pressing and holding in the [VRF]button for two seconds.3. To switch VRF off, press the [VRF] button until the“” icon shows “ ” in the FLT column of theReceiver Configuration Indicator on the display; thisconfirms that the VRF circuit has been removed fromthe incoming received signal path.Receiver Configuration Indicator[VRF] Knob[VRF] ButtonADVICE:The VRF filter affects both the Main (VFO-A) and Sub(VFO-B) bands.The VRF Filter operational status will be memorizedindependently on each VFO in the VFO stack.QUICK POINT:The VRF filter, utilizing high-quality coils and capacitorsthat provide high Q, yields a passband that is approximately20% to 30% the width of a traditional, fixed bandpass fil-ter. As a result, significantly more “unwanted” signal re-jection is provided. Within each Amateur band, the fol-lowing adjustment steps are provided, if you wish to skewthe response in a particular direction so as to enhance in-terference rejection even more. The actual “sound” of thesignal you are listening to will remain unchanged, how-ever.Offset Tuning IndicatorAMATEUR BAND1.8 MHz3.5 MHz5 MHz7 MHz10 MHz14 MHz18 MHz21 MHz24.5 MHz28 MHzVRF ADJUSTMENT STEPS62 steps62 steps62 steps62 steps30 steps30 steps20 steps20 steps20 steps20 steps

Page 54 FT-2000D OPERATING MANUALR.FLT (ROOFING FILTERS)Narrow-band Roofing Filters of 15 kHz, 6 kHz, and 3 kHz bandwidths are provided in the first IF, right after the first mixer.These filters provide protection fort the 2nd mixer, DSP, and other circuitry that follow and can dramatically improvereception on a very crowded band (during a contest, etc.). Typically, the AUTO selection mode is satisfactory for mostoperating situations, but in an extremely crowded phone band you may wish to select, for example, the 3 kHz roofing filterfor SSB operation.INTERFERENCE REJECTION (SIGNALS OFF FREQUENCY BY JUST A FEW KHZ)Press the [R.FLT] button to toggle the RoofingFilter selection.AUTO 15 kHz 6 kHz 3 kHz AUTOADVICE:The Roofing filter selection affects the Main band(VFO-A) only. The Sub band’s (VFO-B) Roofing fil-ter is fixed at a bandwidth of 15 kHz.As you repeatedly press the [R.FLT] button, you willobserve changes in the notation in the R.FLT columnof the Receiver Configuration Indicator on the display,denoting theRoofing Fil-ter currentlyin use.Typically, this selection will be set to “AUTO.”The Roofing Filter selection will be memorized inde-pendently on each VFO in the VFO stack.QUICK POINT:The “AUTO” selection of the Roofing Filter is basedon the operating mode. However, you may overridethe automatic selection, if band conditions warrant adifferent (usually, a tighter) selection.The AUTO mode Roofing Filter selections are shownbelow:AM/FM/FM-PKT: 15 kHzLSB/USB/PKT: 6 kHzCW/RTTY: 3 kHzWhen the Roofing filter mode is set to “AUTO” andthe Noise Blanker is turned On, the Roofing Filter band-width will automatically be set to 15 kHz, as this set-ting provides the most effective noise blanking. How-ever, you still may override the automatic setting, andselect a more narrow Roofing Filter. Noise blankingmay be compromised, however, with a tighter RoofingFilter in the line.TERMINOLOGY:A “Roofing Filter,” as its name implies, places a “Roof”over the receiver’s IF system bandwidth. This “Roof” pro-tects the circuitry downstream from the first mixer frominterference, just as a roof on a house protects the contentsfrom rain and snow.Receiver Configuration Indicator[R.FLT] Button

Page 55FT-2000D OPERATING MANUALCONTOUR CONTROL OPERATIONThe Contour filtering system provides a gentle perturbation of the IF filter passband, so as to suppress or enhance certainfrequency components, thus enhancing the sound and/or readability of a received signal.INTERFERENCE REJECTION (SIGNALS WITHIN 3 KHZ)1. Press the [CONTOUR] button. The Contour notationwill appear in the display to confirm that the Contourfilter is engaged.2. Rotate the [CONTOUR] knob to achieve the mostnatural-sounding audio reproduction on the incomingsignal.3. To cancel Contour tuning, press the [CONTOUR] but-ton once more.ADVICE:The Contour filter affects the Main band (VFO-A) only.You may observe the graphically-depicted peak posi-tion of the CONTOUR Filter in the CONTOUR indi-cator on the display.[CONTOUR] Button[CONTOUR] KnobQUICK POINT:The steep slopes of the DSP filtering can, when adjusted aggressively, impart an unnatural sound to an incoming signal.Oftentimes, though, a narrow bandwidth is not the key to improving copy; the incoming signal itself may have undesirableor excessive frequency components, especially in the low-frequency range around 100-400 Hz. By judicious use of theContour 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 otherfiltering systems.With reference to Figure “B,” note the initial posi-tion (12 o’clock) of the [CONTOUR] knob whenthe [CONTOUR] button is pushed. You may ob-serve the “indentation” in the receiver passbandwhere the Contour filter is placing a low-Q “notch”(per the setting of Menu item “090,” referencedabove). Counter-clockwise rotation (to the left) ofthe [CONTOUR] knob causes the indentation tomove towered a lower frequency within the pass-band, while clockwise rotation (to the right) causesthe indentation to move toward a higher frequencywithin the passband. By removing interference orunwanted frequency components on the incomingsignal, it is possible to make the desired signal riseout of the background noise/interference, enhanc-ing intelligibility.IFBANDW IDTHIFBANDWIDTHIFBANDWIDTHCONTOUR Indicator[CONTOUR] buttonFully Counter-Clockwise[CONTOUR] buttonFully Clockwise[CONTOUR] buttonCenter[CONTOUR] buttonFully Counter-Clockwise[CONTOUR] buttonFully Clockwise[CONTOUR] buttonCenterCONTOUR GAIN “MINUS” CONTOUR GAIN “PLUS”The Contour filter’s level (either nulling or peaking)may be adjusted using Menu item “090 rdSP CNTRLV.” The factory default setting is for a null of “–15”(dB).The bandwidth over which the Contour filter effect isapplied may be adjusted using Menu item “091 rdSPCNTR WI.” The factory default setting is “10.”When the optional DMU-2000 Data Management Unitis connected, the Audio Scope (on the “Oscilloscope”page) is particularly useful when adjusting the Con-tour control. Not only can you see the effect of thenull/peak of the Contour system, but you also can seethe position of the null/peak with respect to frequencycomponents of interest on the incoming signal. Youmay then observe (on the Audio Scope) the effect ofthe Contour control while listening to the effect on thesignal, and this will help build your intuition on howbest to use Contour tuning in the future.AB C

Page 56 FT-2000D OPERATING MANUALIF SHIFT OPERATION (SSB/CW/RTTY/PKT/AM MODES)IF Shift allows you to vary the DSP filter passband higher or lower, without changing the pitch of the incoming signal, so asto reduce or eliminate interference. Because the carrier tuning frequency is not varied, there is no need to re-tune theoperating frequency when eliminating the interference. The total passband tuning range for the IF Shift system is ±1 kHz.INTERFERENCE REJECTION (SIGNALS WITHIN 3 KHZ)Rotate the [SHIFT] knob to the left or right to reduce theinterference.ADVICE:The [SHIFT] knob affects the Main band (VFO-A)only. However, you may shift the Sub band (VFO-B)filter passband via Menu items “042 S-iF LSB SET”through “049 S-iF PKT-USB.”The position of the passband set by the IF Shift can beobserved on the display.[SHIFT] knobSHIFT IndicatorIFBANDWIDTHIFBANDWIDTHIFBA NDW ID THDesired Signal Desired Signal Desired SignalQRMQRMReferring to Figure “A,” note the depiction of theIF DSP filter as the thick line, with the [SHIFT]knob in the 12 o’clock position. In Figure “B,” aninterfering signal has appeared inside the originalpassband. In Figure “C,” you can see the effect ofrotating the [SHIFT] knob so as to reduce the in-terference level by moving the filter passband sothat the interference is outside of the passband.AB C

Page 57FT-2000D OPERATING MANUALWIDTH (IF DSP BANDWIDTH) TUNING (SSB/CW/RTTY/PKT MODES)The IF Width tuning system allows you to vary the width of the DSP IF passband, so as to eliminate interference. Moreover,the bandwidth may actually be expanded from its default setting, should you wish to enhance incoming signal fidelity wheninterference on the band is low.INTERFERENCE REJECTION (SIGNALS WITHIN 3 KHZ)Rotate the [WIDTH] knob to adjust the bandwidth.Counter-clockwise rotation reduces the bandwidth, whileclockwise rotation increases the bandwidth.ADVICE:The IF Width affects the Main band (VFO-A) only.The bandwidth of the IF can be observed on the dis-play.CAUTION:When rotating the [WIDTH] control fully counter-clock-wise, the transition between 50 Hz and 25 Hz bandwidthmay be accompanied by a “ping” sound, depending on theamount of noise present. This is a normal condition, andyou should turn down the volume, when wearing head-phones, to minimize the amplitude of this momentarysound.Referring to Figure B, you can see the default band-width with the [WIDTH] knob set to the 12 o’clockposition.By rotating the [WIDTH] knob to the left, the band-width will narrow (see Figure “A”), while rotationof the [WIDTH] knob to the right, as depicted inFigure “C,” will widen the bandwidth.The default bandwidths, and total bandwidth ad-justment range, will vary according to the operat-ing mode:SSB Mode: 200 Hz ~ 4.0 kHz (2.4 kHz)CW Mode: 25 Hz ~ 2.4 kHz (2.4 kHz)RTTY/PKT Modes: 25 Hz ~ 2.4 kHz (500 Hz): bandwidth at 12 o’clock position of [WIDTH] knob.[WIDTH] KnobWIDTH IndicatorIFBANDWIDTHIFBANDWIDTHIFBA NDW ID THUsing IF Shift and Width TogetherThe IF Shift and Variable IF Width features togetherform a very effective interference-fighting filter-ing system.For example, in Figure “A” you can see how inter-ference has appeared both on the high and low sidesof the desired signal. By rotating the [WIDTH]knob, as shown in Figure “B,” the interference fromone side can be eliminated, and by re-positioningthe [SHIFT] knob (Figure “C”), the interferenceon the opposite side can be removed, without re-introducing the interference previously eliminatedin Figure “B.”Advice: For best interference reduction, the Widthand Shift features are the primary tools you shoulduse. After narrowing the bandwidth (Width) and/oradjusting the center of the passband (Shift), theContour control may also yield additional signal-enhancement benefits on the net residual bandwidth.What’s more, the IF Notch Filter (see the next sec-tion) may also be utilized, in conjunection with thethree other filter systems, to significant advantage.AB CIFBANDWIDTHIFBANDWIDTHIFBANDWIDTHDesired Signal Desired Signal Desired SignalQRMQRMQRMQRMQRMQRMAB C

Press the [NOTCH] button. The Notch characteristicwill appear in the display to confirm that the Notchfilter is engaged.2. Initially, rough adjustment of the center frequency ofthe IF Notch Filter is adjusted using the outer[COARSE] knob; thereafter, fine tuning of the Notchfrequency is adjusted using the inner [FINE] knob.3. To switch the IF Notch filter off, press the [NOTCH]button once more. The Notch notation will turn off,confirming that the IF Notch filter is no longer operat-ing.ADVICE:The IF Notch filter affects the Main band (VFO-A)only.You may observe the graphically-depicted peak (maxi-mum null) position of the IF Notch Filter in the NOTCHindicator on the display.The width of the IF Notch null may be adjusted usingMenu item “092 rdSP NOTCH W.” Both “Wide” and“Narrow” selections are available, with “Narrow” pro-viding the least disruption of the “desired” signal.When the optional DMU-2000 Data Management Unitis connected, the effect of the IF Notch filter may beobserved on the Audio Scope (on the “Oscilloscope”page). The Notch will be observed as a “dip” in thenoise platform observed. What’s more, the “Waterfall”display may be used to observe the effect of the IFNotch filter, which will appear as a white area in thecolored background area. The tuning rate for the IFNotch is somewhat slow while you adjust the [FINE]knob, so the use of the Waterfall display to confirmproper adjustment is highly recommended.The performance of the IF Notch filter is shown inFigure “A,” where the effect of rotation of the[NOTCH] knobs is depicted. In Figure “B,” youcan see the notching effect of the IF Notch filter asyou rotate the [NOTCH] knobs to eliminate theincoming interference.[NOTCH] Button[NOTCH] KnobNOTCH IndicatorIFBANDWIDTHQRM(Heterodyne)QRM(Heterodyne)IFBANDWIDTHDesired Signal Desired SignalAB

Page 62 FT-2000D OPERATING MANUALAGC (AUTOMATIC GAIN CONTROL)The AGC system is designed to help compensate for fading and other propagation effects, with characteristics that can beof particular value on each operating mode. The basic objective of AGC is to maintain a constant audio output level oncea certain minimum threshold of signal strength is achieved.Main Band (VFO-A) AGC SelectionPress the [AGC] button repeatedly to select the desiredreceiver-recovery time constant. You will observe the AGCstatus notation in the AGC column of the Receiver Con-figuration Indicator on the display, denoting the AGC re-ceiver-recovery time currently in use. For most operation,we recommend the “AUTO” mode. Additionally, you maydisable the AGC by pressing and holding in the [AGC]button for two seconds.Sub Band (VFO-B) AGC Selection1. Press the [B] button.2. Within five seconds of pressing the [B] button (whilethe imbedded orange LED is blinking), press the [AGC]button repeatedly to select the desired receiver-recov-ery time constant. You will observe the AGC notationbelow the Sub frequency on the display, denoting theSub receiver’s current AGC receiver-recovery time. Formost operation, we recommend the “AUTO” mode.Additionally, you may disable the AGC by pressingand holding in the [AGC] button for two seconds.NOTE:Pressing the [AGC] button allows selection of the desiredreceiver-recovery time constant. Normally, the “AUTO”selection is satisfactory for most situations, but in the eventof operation on a crowded band where you wish to receivea 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 press-ing and holding in the [AGC] button, the S-meter will nolonger deflect. Additionally, you will likely encounter dis-tortion on stronger signals, as the IF amplifiers and thefollowing stages are probably being overloaded.QUICK POINTSeveral aspects of AGC performance may be configuredvia the Menu. However, because AGC can have such aprofound impact on overall receiver performance, we gen-erally do not recommend any changes to the AGC Menuselections until you are thoroughly familiar with the per-formance of the FT-2000D.TERMINOLOGY:Automatic Gain Control, or AGC, is a circuit that sensesthe incoming signal strength, and then limits the gains ofthe RF and IF stages so as to keep the output audio vol-ume at a more-or-less constant level. AGC also protectsthe RF, IF, Audio, and DSP stages from overload, as itlimits the signal strength that is allowed to flow, irrespec-tive of the input signal level.TOOLS FOR COMFORTABLE AND EFFECTIVE RECEPTION[B] Button[AGC] ButtonOPERATING MODELSBUSBCWAMFMRTTYPKT (FM)PKT (LSB)AUTO AGC SELECTIONSLOWSLOWFASTFASTFASTSLOWFASTSLOW

The FT-2000D, however, includes an innovative Sloped AGC sys-tem on the Main band (VFO-A) receiver, that allows the audio volume torise and fall slightly according to signal strength. Although the rise/fall slopeis not dramatic, it is sufficient to allow you to use your ear to discern andseparate signals according to signal strength, not just audio frequency.Using Sloped AGC1.

The operating mode is selected using the [MODE]buttons to the left of the Main Tuning Dial knob, andthe VFO (A or B) to which the selection is applied isselected by the [A] or [B] button above the [MODE]buttons. Usually, the [A] button glows Red, signifyingthat the Main band (VFO-A) is be-ing adjusted. Similarly, pressing the[B] button will cause its indicator toblink Orange for five seconds, sig-nifying Sub band (VFO-B) adjust-ment. Therefore, press the [A] or [B]button to select the desired VFO,then press the [LSB] or [USB] but-ton to select one of the SSB modes.For AM operation, press the [AM/FM] button repeatedly until the im-bedded LED glows red.QUICK POINT:By convention, LSB is used in the 7 MHz and lowerAmateur bands for SSB communication, and USBis used on the 14 MHz and higher bands (the 10MHz band is used for CW and data modes only).When the [AM/FM] button glows orange, it indi-cates that FM operation is engaged.2. Rotate the Main Tuning Dial knob to adjust the oper-ating frequency. Alternatively, you may use the [UP]/[DWN] scanning buttons on the MH-31B8 Hand Mi-crophone to sweep up or down the current band.3. Press the microphone’s PTT (Push To Talk) switch tobegin transmission; speak into the microphone in anormal voice level.ADVICE:The “ ” indicator will light up in the frequencydisplay area, confirming that transmission is inprogress.When transmitting in the AM mode, rotate the [RFPWR] knob so as to set a maximum (carrier) poweroutput of 50 Watts.4.

How-ever, using Menu item “050 A3E MICGAIN,” you mayset a different fixed value, or choose the “Ur” option,which then lets you use the front panel [MIC] knob toset the microphone gain in the AM mode. In this case,the [MIC] knob should not be advanced to the pointwhere the ALC meter deflects. In many cases, the samesetting as used on SSB will be satisfactory.5.

Page 65FT-2000D OPERATING MANUALSSB/AM MODE TRANSMISSIONADVICE:ALC meter deflection may be caused by excessive drivepower, but also by reflected power detected in the an-tenna system. If the impedance presented to the trans-ceiver is different from 50 Ohms, ALC meter actionmay be observed that is not related to the proper set-ting of the [MIC] (gain) knob. Therefore, we recom-mend that you make [MIC] knob adjustments into adummy load or antenna system presenting an imped-ance very close to 50 Ohms.Rotate the [RF PWR] knob to set the desired poweroutput. Clockwise rotation of the [RF PWR] knob willincrease the power. The adjustmentrange is between 10 Watts and 200Watts, and you should always use theminimum power necessary for main-taining reliable communications.When performing tests (such as the setup of the [MIC]or [RF PWR] knobs), be sure to check the frequencybefore transmitting, so as to avoid interference to oth-ers who may already be using the frequency.Four techniques for exercising Transmit/Receive con-trol are provided on the FT-2000D, and you maychoose the technique(s) that best suit your operatingneeds:Pressing the microphone’s PTT switch will engagethe transmitter.The rear panel PTT jack may be connected to afoot switch or other manual switching device inorder to engage the transmitter.Pressing the front panel [MOX] button will lockthe transmitter on. Press the [MOX] button againto return to receive.The VOX (Voice Operated Xmit) circuit will en-gage the transmitter automatically when you speakinto the microphone. For details of VOX opera-tion, see page 78.

Page 66 FT-2000D OPERATING MANUALThe Automatic Antenna Tuner (hereinafter referred to as the “ATU”) built into each FT-2000D is crafted to ensure a 50-Ohm load for the final amplifier stage of the transmitter. We recommend that the ATU be used whenever you operate on theFT-2000D.ADVICE:The ATU of the FT-2000D, being located inside the station, only adjusts the impedance presented to the transceiver atthe station end of your coaxial cable feedline. It does not “tune” the SWR at the antenna feedpoint itself. When design-ing and building your antenna system, we recommend that every effort be made to ensure a low SWR at the antennafeedpoint.The ATU of the FT-2000D includes 100 memories for tuning data. Eleven of these memories are allocated, one perAmateur band, so that each band has at least one setting preset for use on that band. The remaining 89 memories arereserved for the 89 most-recent tuning points, for quick frequency change without the need to retune the ATU.The ATU in the FT-2000D is designed to match impedances within the range of 16.5 Ohms to 150 Ohms, correspond-ing to an SWR of 3:1 or less on the HF amateur bands (6 m amateur band: 25 Ohms to 100 Ohms, corresponding to anSWR of 2:1 or less). Accordingly, simple non-resonant whip antennas, along with random-length wires and the “G5RV”antenna (on most bands) may not be within the impedance matching range of the ATU.ATU OPERATIONUSING THE AUTOMATIC ANTENNA TUNER1. Rotate the [RF PWR] knob fully clockwise (to theright).2. Use the Main Tuning Dial knob to set the radio to thedesired operating frequency within the Amateur band.3. Press the [TUNE] button momentarily to place the ATUin the transmit line (no adjustment/tuning will occuryet). The “ ” icon will appear in the display.QUICK POINT:The momentary press of the [TUNE] button will turnthe tuner on, and the microprocessor will automaticallyselect the tuning point closest to the current operatingfrequency.4. Press and hold in the [TUNE] button for two secondsto begin automatic tuning. The transmitter will be en-gaged, and the “ ” icon will blink while tuning isin progress. When the optimum tuning point has beenreached, the radio will return to receive, and the“” icon will again glow steadily (instead ofblinking).5. While tuning around the band using the Main TuningDial knob, you will observe that the “ ” iconblinks momentarily every 10 kHz. This momentaryblinking indicates that a new tuning window has beenentered. If you want to save tuning data associated withthis 10 kHz window, repeat step 4 (above) for eachsuch window. On bands like 1.8 MHz where the im-pedance may change rapidly, the storage of a numberof tuning points is recommended.6. To disconnect the ATU from the transmit line, pressthe [TUNE] button momentarily. The “ ” iconwill turn off, confirming that the ATU has been turnedoff. In the “Off” mode, the transceiver will be directlyconnected to the coaxial cable connected to your an-tenna, and will operate based on whatever impedanceis present at the station end of the coax.ADVICE:The ATU circuit is located between the final amplifier andthe rear-panel antenna jack; reception is not affected bythe ATU.QUICK POINT:As shipped from the factory, only one ATU alignmentpoint is saved on each Amateur band. This was memo-rized during the final alignment and performance veri-fication stages on the production line.The momentary flickering of the “ ” icon occurswhenever you cross over into a new 10 kHz ATUmemory window.NOTE:Please check the operating frequency before beginning thetuning process, to be sure you are not interfering with oth-ers who may already be using the frequency.TERMINOLOGY:Antenna Tuner Memories: The microprocessor of the ATUmakes a note of the positions of the tuning capacitors andthe selected inductors, and stores the data for each 10 kHzwindow in which tuning has occurred. This eliminates theneed to re-tune every time you return to a frequency onwhich you already have completed the tuning process.[DNR] Knob[DNR] ButtonNOTCH Indicator

The antenna system as seen by the transmitter is shown.In Figure 2, the operator has changed frequency, and the “ ” icon has become appeared. The operator presses andholds in the [TUNE] button for two seconds to begin impedance matching using the ATU.If a high SWR conditions exists (above 3:1), corrective action must be taken in the antenna system to bring the impedancecloser to 50 Ohms. Besides the fact that the ATU will refuse to memorize settings on frequencies where the SWR exceeds3:1, the high SWR may indicate a mechanical failure in the feed system, and such failures can lead to the generation ofspurious signals causing TVI, etc.About ATU MemoriesSWR (Post-tuning) Less than 1.5:1The tuning settings are committed to the ATU memory.SWR (Post-tuning) Greater than 1.5:1Tuning data will not be retained in memory. If you return to the same frequency, the tuning process must be repeated.SWR (Post-tuning) Greater than 3:1The “ ” icon will light up, and tuning settings, if achieved, will not be memorized.

Page 68 FT-2000D OPERATING MANUALLITHIUM BATTERY REPLACEMENTThe memories for the ATU are backed up by a common Lithium backup battery (type CR2032 or equivalent). After two ormore years of heavy use, you may notice that the tuner memories are not being maintained, and that you have to re-tunewhen returning to a frequency on which you had previously stored tuning data.In this case, please replace the ATU Backup Battery using the following procedure:1. Turn the FT-2000D’s [POWER] switch “off,” thenturn the FP-2000’s [POWER] switch “off.”2. Unplug the AC cable from the AC jack on the FP-2000 rear panel, then disconnect the DC cable (hav-ing two connectors) from the FT-2000D rear panel.3. Referring to Figure 1, remove the three screws from eachside of the transceiver and three screws from the topedge of the rear panel. Slide the top case toward to therear about 1/2 inch (1 cm), then remove the top case.4. Turn the transceiver up side down.5. Remove the seven screws affixing the bottom case, andthen remove the bottom case (Figure 2).6. Locate the Lithium battery on the left side of the Con-trol Unit (Figure 3).7. Turn the BACKUP switch “off.”8. Follow the guidelines in Figure 4, and remove the oldbattery, replacing it with a new one of the identical type.9. Connect the DC cable (having two connectors) to theFT-2000D rear panel, then connect the AC cable tothe AC jack on the FP-2000 rear panel.10. Turn the FP-2000’s [POWER] switch “on,” then turnthe FT-2000D’s [POWER] switch “on.” Use extremecaution, as high voltages are present inside the trans-ceiver!11. Turn the BACKUP switch “on.”12. Turn the FT-2000D’s [POWER] switch “off,” thenturn the FP-2000’s [POWER] switch “off.”13. Unplug the AC cable from the AC jack on the FP-2000 rear panel, then disconnect the DC cable (hav-ing two connectors) from the FT-2000D rear panel.14.

Page 69FT-2000D OPERATING MANUALADJUSTING THE SSB TRANSMITTED BANDWIDTH (SSB MODE)For transmission on SSB, a default bandwidth of 2.4 kHz is provided. This bandwidth provides reasonable fidelity alongwith good talk power, and is typical of the bandwidth used for decades during SSB transmission. However, the bandwidthmay be varied by the operator, so as to provide different levels of fidelity or talk power, according to your preferences.Here’s how to adjust the transmitted bandwidth on SSB:1. Press the [MENU] button to engage the Menu.2. Rotate the Main Tuning Dial knob so as to select Menuitem “083 A3J TX BPF.”3. Rotate the [SUB VFO-B] knob to select the desiredbandwidth. The available selections are 3000/50-3000/100-2900/200-2800/300-2700/400-2600, and the default is 300-2700 Hz. A wider band-width will provide greater fidelity, while a narrow band-width will compress the available transmitter powerinto less spectrum, resulting in more “talk power” forDX pile-ups.4. Press and hold in the [MENU] button for two secondsto save the new setting and exit to normal operation.ADVICE:The Transmit Monitor is very helpful way of verifyingthe effects on fidelity of changing the bandwidth. Press-ing the [MONI] button then adjusting the [MONI] knobfor a comfortable listening level while you are trans-mitting, you will be able to hear the difference in soundquality as you make changes.When the optional DMU-2000 Data Management Unitis connected, you may verify the effect of your adjust-ments of the transmitted bandwidth by observing theAudio Scope on the “Oscilloscope” page.QUICK POINTS:The higher fidelity associated with wide bandwidth willbe particularly enjoyable on the low bands, during lo-cal rag-chew QSOs.The “3000” setting is a special hi-fidelity setting,whereby the transmitted bandwidth is in excess of 3kHz. This selection, in conjunction with judicious ad-justment of the Parametric Microphone Equalizer (seenext chapter) can provide truly outstanding fidelity andvery natural-sounding audio.When using the wider bandwidth selections (especially“3000”), the apparent power output from the transmit-ter may seem lower. This is because the available powerfrom the transmitter is being distributed over a widerbandwidth, and the power detection circuitry does notcompensate for the effect of the bandwidth selection(it is calibrated in the default 2.4 kHz bandwidth).Main Tuning Dial Knob [SUB VFO-B] Knob[MENU] ButtonENHANCING TRANSMIT SIGNAL QUALITY

Page 70 FT-2000D OPERATING MANUALENHANCING TRANSMIT SIGNAL QUALITYPARAMETRIC MICROPHONE EQUALIZER (SSB/AM MODES)The FT-2000D includes a unique Three-Band Parametric Microphone Equalizer, that provides precise, independent con-trol over the low-, mid-, and treble-ranges in your voice wave-form. You may utilize one group of settings for when thespeech processor is off, and an independent group of settings for when the speech processor is on. The speech processorfeature is described on next chapter.QUICK POINT:The Parametric Equalizer is a unique technique for adjusting the signal quality. Because the three ranges may be adjustedso precisely, it is possible to craft a response that provides a more natural and pleasant sound than you have ever experi-enced before. Effective “talk power” can also be significantly enhanced.The aspects of configuration that you may adjust on the Parametric Equalizer are:Center Frequency: The center frequency of each of the three bands may be adjusted.Gain: The amount of enhancement (or suppression) within each band may be adjusted.Q: The bandwidth over which the equalization is applied may be adjusted.SETUP THE PARAMETRIC MICROPHONE EQUALIZER1. Connect the microphone to the MIC jack.2. Set the [RF PWR] knob to its minimum value, so as notto cause interference to other users during adjustment.ADVICE:We recommend you consider connecting a dummyload to one of the Antenna jacks, and monitor yoursignal on a separate receiver, so as to prevent inter-ference to other users.You will have the best chance of hearing the ef-fects of adjustments if you wear headphones (con-nected to the monitor receiver) while monitoringyour transmitted signal.3. If you adjust the Parametric Microphone Equalizerwhen the speech processor is disabled, press the[PROC] button until the “ ” icon will appear inthe display. If you adjust the Parametric MicrophoneEqualizer when the speech processor is engaged, pressthe [PROC] button until the “ ” and “ ”icons will appear in the display.4. Press the [MONI] button, if you want to listen on theFT-2000D’s internal monitor.5. Press the [MENU] button momentarily. The Menu listwill appear in the display.6. Rotate the Main Tuning Dial knob to find the “EQ”Menu area, containing Menu items “123” through“131;” these parameters apply to the adjustment of theParametric Microphone Equalizer when the speechprocessor is disabled. Menu items “132” through “140”apply to the adjustment of the Parametric MicrophoneEqualizer when the speech processor is engaged.7. Rotate the [SUB VFO-B] knob to perform adjustmentsto a particular Menu item.8. Close the PTT switch, and speak into the microphonewhile listening to the effects of the changes you are mak-ing (in step 6). Because the overall effect on the soundwill change with each adjustment you make, you shouldmake several passes through each adjustment area, tobe sure that you are achieving the optimum setting.9. When you have completed all adjustments, press andhold in the [MENU] button for two seconds to savethe new settings and exit to normal operation. If youonly press the [MENU] button momentarily to exit,any changes you performed will not be stored.ADVICE:To roll off excessive bass response in a wide-range studiomicrophone, try putting a 10 dB null at 100 Hz with abandwidth of “1” or “2,” do about a 3 dB null centered on800 Hz with a bandwidth of “3,” and then put an 8 dBpeak centered on 2100 Hz with a bandwidth of “1.” Theseare starting recommendations; each microphone and user’svoice will be different, often requiring different settings.[RF PWR] Knob[MONI] Button Main Tuning Dial Knob[SUB VFO-B] Knob[MENU] Button

Press the [MENU] button; the Menu list will appear inthe display.2. Rotate the Main Tuning Dial knob to select Menu item“141 tGEn BIAS.”3. Rotate the [SUB VFO-B] knob to select the desiredBIAS level “0 - 100” to set the transceiver for opera-tion anywhere between Class-A and Class-AB (whichhas lower heat dissipation but higher distortion prod-ucts).Clockwise rotation of the [SUB VFO-B] knob in-creases the BIAS, and menu setting “100” will placethe transmitter in fully Class-A operation. Counter-clockwise rotation of the [SUB VFO-B] knob willmove the transmitter toward Class-AB operation, andmenu setting “Ab” will place the transmitter in fullyClass-AB operation.4. Press and hold in the [MENU] button for two secondsto save the new setting and exit to normal operation.To exit from the Class-A mode, repeat the above proce-dure, rotating the [SUB VFO-B] knob to select “Ab” instep 3 above.Main Tuning Dial Knob [SUB VFO-B] Knob[MENU] ButtonCLASS-AB CLASS-AId: Drain CurrentVDS: Drain VoltageADVICEWe recommend that menu item “141 tGEn BIAS” is pro-grammed to [C.S] button for easy class-A operation.

Page 75FT-2000D OPERATING MANUALENHANCING TRANSMIT SIGNAL QUALITYLOW- DISTORTION CLASS-A OPERATIONADVICEDuring Class-A operation, ten Amps of Bias current will be flowing, regardless of the modulation level that leads toactual power output. Therefore, if the ambient temperature in your operation location is high, the transceiver tempera-ture may rise as well, due to the high bias level (which must be dissipated as heat). Depending on the temperature, youmay wish to reduce the BIAS level using menu item “141 tGEn BIAS,” so as to reduce the amount of heat beinggenerated.When the optional DMU-2000 Data Management Unit is connected, you can monitor the heat sink temperature on theafter-maket monitor, you can always be aware of a rise in temperature during Class-A operation. Normally, the tempera-ture is below 80 °C; if it rises to near or above this value, however, we recommend you adjust the BIAS level towardClass-AB (decrease the numerical value) via menu item “141 tGEn BIAS,” so as to reduce the heat being dissipated.An innovative aspect of the “Class-A” mode is that the actual power output is always limited to 75 Watts. So eventhough you might adjust the BIAS lebel in the direction of Class-AB operation, the power output will not rise; thiseliminates the need, for example, to re-tune your linear amplifier, if used.QUICK POINTClass-A operation provides a significant improvement in transmitter distortion suppression. During Class-A, the 3rd-order IMD products are typically suppressed 50 dB, while the 5th- and higher-order IMD products (that can cause“splatter” that interferes with others) will typically be suppressed 70 dB or more.If you are using a linear amplifier such as the VL-1000, the low distortion produced by the FT-2000D’s transmittermeans that these intermodulation distortion products will not exist to be amplified by your linear.High-Power 200-Watt Final Amplifier StageThe final amplifier stage of the FT-2000D utilizes a pair of ST Micro Electronics Corp. SD2931 MOSFET devicesoperating at 50 Volts. The push-pull configuration provides low distortion along with high power output. The 120 mmthermostatically-controlled cooling fan directs forced air across the heat sink, should the heat sink temperature exceedthe temperature that will trigger the thermostat.Class-AB 200W PEP IMDClass-A 75W PEP IMD

Setup of the VOX system takes only a few seconds.1. To start, set the [VOX] and [DELAY] knobs fullycounter-clockwise (to the left).2. Press the [VOX] button to engage VOX operation.3. Speak into the microphone in a normal voice level,and rotate the [VOX] knob clockwise (to the right) untilthe point where your voice input activates the trans-mitter.ADVICE:Do not advance the setting of the [VOX] knob toomuch, because to do so will make the transmitter re-spond to minor background noises in your station.4. Now stop speaking, and note the amount of time it takesfor the receiver to recover. If the hang time is too longor too short; rotate the [DELAY] knob, while speakingbriefly into the microphone and then pausing, so as toset the desired hang time. Clockwise rotation of the[DELAY] control will increase the hang time.5. To exit from VOX operation, press the [VOX] buttononce more. We recommend doing this if you are goingto leave your station, to prevent inadvertent activationof the VOX system by a ringing nearby telephone,speaker audio from a TV, etc.MONITOR (SSB/AM/FM MODES)You may listen to the quality of your transmitted signal using the Monitor feature.1. Press the [MONI] button. The “ ” icon will ap-pear in the display, indicating that the Monitor is turnedon.2. During transmission, rotate the [MONI] knob to ad-just the audio level from the Monitor. Clockwise rota-tion of this knob will increase the volume level.3. To switch the Monitor off again, press the [MONI]button once more. The “ ” icon will turn off, con-firming that the Monitor is now disengaged.ADVICE:If you are using the speaker for monitoring, instead ofheadphones, excessive advancement of the [MONI]knob can cause feedback to occur. Additionally, thisfeedback can cause the VOX system to hang up in aloop, making it impossible to return to receive. There-fore, we recommend the use of headphones, if at allpossible, or the minimum usable setting of the [MONI]knob, if the speaker must be used.Because the Monitor feature utilizes a sampling of thetransmitter’s IF signal, it can be very useful for check-ing the adjustment of the Speech Processor or Para-metric Equalizer on SSB, and for checking the generalsignal quality on AM and FM.TRANSMITTER CONVENIENCE FEATURES[VOX] Knob[DELAY] Knob[VOX] ButtonADVICE:The Anti-Trip setting sets the negative feedback of re-ceiver audio to the microphone, to prevent receiveraudio from activating the transmitter (via the micro-phone) can be adjusts via Menu item “040 GEnEANTIVOX.”VOX operation may be engaged on either Voice modes(SSB/AM/FM) and on AFSK-based Data modes.

On the DX sideof the pile-up, everyone calling precisely on the same CWfrequency will sound like a single tone! So you may havemore success if you use the RX Clarifier to find a hole inthe pile-up, instead of trying to zero-beat the last stationworked by the DX station.(TX Frequency < RX Frequency)(TX Frequency = RX Frequency)(TX Frequency > RX Frequency)

Page 80 FT-2000D OPERATING MANUALSPLIT-FREQUENCY OPERATIONA powerful capability of the FT-2000D is its flexibility in Split Frequency operation, using the Main (VFO-A) and Sub(VFO-B) frequency registers. This makes the FT-2000D especially useful for high-level DX-pedition use, as the Splitoperation capability is very advanced and easy to use.TRANSMITTER CONVENIENCE FEATURES1. Set the Main (VFO-A) frequency as desired.2. Set the Sub (VFO-B) frequency.3. Now press the [SPLIT] button. Thefront panel switch/LEDs will look likethis:Main (VFO-A)[RX] switch “ON” (LED glowsGreen)[TX] switch “OFF” (LED Off)Sub (VFO-B)[RX] switch “OFF” (LED Off)[TX] switch “ON” (LED glows Red)During Split operation, the Main (VFO-A) register will beused for reception, while the Sub (VFO-B) register will beused for transmission. If you press the [SPLIT] buttononce more, Split operation will be cancelled.You may also press the Main [TX] switch located aboveand to the right of the Main Tuning Dial knob to returntransmit frequency control to the Main (VFO-A) side,thereby cancelling Split operation.ADVICE:During normal (non-split) VFO-A operation, you maysimply press the Sub (VFO-B) [TX] switch (locatedabove and to the right of the [SUB VFO-B] knob) toengage Split operation. The Sub [TX] indicator willglow Red when you press the switch.During Split operation, pressing the [AB] button willreverse the contents of the Main and Sub VFOs. Pressthe [AB] button once more to return to the originalfrequency alignment.During Split operation, if you press the [RX] switchabove and to the right of the [SUB VFO-B] knob, youwill engage Dual Receive operation, and now can lis-ten to both sides of the DX pile-up, while transmittingon the Sub (VFO-B) frequency. This is very useful formaintaining the timing of your calls, while also moni-toring both sides of the pile-up.During Split operation, you may also listen the TX fre-quency temporarily while pressing the [TXW] button(below and to the left of the Main Tuning Dial knob).It is possible to set different operating modes (for ex-ample, LSB and USB) on the two VFOs used duringSplit operation.During Split operation, it also is possible to set theMain and Sub VFOs to different Amateur bands.

The CW LED will blink forthree seconds if you select CW Reverse.2. Rotate the Main Tuning Dial knob to select the desiredoperating frequency.3. Press the [BK-IN] button to engage automatic activa-tion of the transmitter when you close the CWkey. The “ ” icon will appear in the dis-play.ADVICE:When you close your CW key, the transmitter willautomatically be activated, and the CW carrier willbe transmitted. When you release the key, trans-mission will cease after a brief delay; the delay timeis user-programmable, per the discussion on page83.As shipped from the factory, the FT-2000D TX/RX system for CW is configured for “Semi-break-in” operation. However, using Menu item “058A1A BK-IN,” you may change this setup for fullbreak-in (QSK) operation, whereby the switchingis quick enough to hear incoming signals in thespaces between the dots and dashes of your trans-mission. This may prove very useful during con-test and traffic-handling operations.4. Operation using your CW key may now proceed.ADVICE:You can monitor your sending by pressing the [MONI]button, and adjusting the [MONI] knob for a comfort-able listening level on the CW sidetone.If you set the [VOX] and [BK-IN] buttons to Off, youmay practice your sending without having the signalgo out over the air (sidetone only).If you reduce power using the [RF PWR] knob, theALC meter reading will increase; this is normal anddoes not indicate any problem whatsoever (becauseincreased ALC voltage is being used to lower thepower).TERMINOLOGY:Semi-break-inThis is a pseudo- “VOX” mode used on CW, wherebythe closure of the CW key will engage the transmitter,and release of the key will allow the receiver to re-cover after a short delay. No signals will be heard be-tween the spaces between dots and dashes (unless thesending speed is extremely slow).Full break-inFull break-in (Also known as “Full QSK”) involvesvery fast switching between transmit and receive, suchthat incoming signals may be heard between the dotsand dashes as you send them. This allows you to hear astation that suddenly starts transmitting on your fre-quency, while you are in the midst of a transmission.[CW] Button[B] Button[A] Button[BK-IN] Button

Page 85FT-2000D OPERATING MANUALCW CONVENIENCE FEATURESCW SPOTTING (ZERO-BEATING)“Spotting” (zeroing in on another CW station) is a handy technique for ensuring that you and the other station are preciselyon the same frequency.For everyday operation, the (CW) [PITCH] knob allows you to set the center of the receiver passband, as well as the offsetpitch of your CW carrier signal, to the tone pitch you prefer to listen to.The Tuning Offset Indicator in the display may also be moved so you can adjust your receiver frequency to center theincoming station on the pitch corresponding to that of your transmitted signal.Using the SPOT SystemWhile pressing the front panel’s [SPOT] button, the Spottone will be heard and the Sub (VFO-B) frequency dis-play will show the Spot tone frequency. This tone corre-sponds to the pitch of your transmitted signal, and if youadjust the receiver frequency to match the pitch of the re-ceived CW signal to that of the Spot tone, your transmit-ted signal will be precisely matched to that of the otherstation.Release the [SPOT] button to turn the Spot tone off.ADVICE:In a tough DX pile-up, you may actually want to usethe SPOT system to find a “gap” in the spread of call-ing stations, instead of zeroing in precisely on the laststation being worked by the DX station. From the DXside, if a dozen or more operators (also using Yaesu’sSPOT system) all call precisely on the same frequency,their dots and dashes merge into a single, long tonethat the DX station cannot decipher. In such situations,calling slightly higher or lower may get your callthrough.The Tuning Offset Indicator in the display may be uti-lized for CW frequency adjustment, as well. Its con-figuration is set via Menu item “010 diSP BAR SEL”at the factory, and the Tuning Offset Indicator is al-ready set to the “CW TUNE” selection.QUICK POINTS:The CW Spotting process utilizes the Spot tone or theTuning Offset Indicator, with the actual offset pitchbeing set by the [PITCH] knob on the front panel. Theoffset pitch may be set to any frequency between 300Hz and 1050 Hz, in 50 Hz steps, and you can eithermatch tones audibly (using the [SPOT] button) or alignthe receiver frequency so that the central red LED onthe Tuning Offset Indicator lights up. Note that thereare 21 “dots” on the Tuning Offset Indicator, and de-pending on the resolution selected, the incoming CWsignal may fall outside the visible range of the bar in-dicator, if you are not reasonably close to the properalignment of tones.The displayed frequency, on CW, normally reflects the“zero beat” frequency of your offset carrier. That is, ifyou were to listen on USB on 14.100.00 MHz to asignal with a 700 Hz offset, the “zero beat” frequencyof that CW carrier would be 14.000.70 MHz; the latterfrequency is what the FT-2000D displays, by default.However, you can change the display to be identical towhat you would see on SSB by using Menu item “061A1A FRQDISP” and setting it to “dIr” instead of itsdefault “OFSt” setting.[SPOT] Button[PITCH] Knob Tuning Offset IndicatorRetune: Shift to Lower Frequency: When the CW reversefeature is activated, theindicator of the Tuning Offset Indicator will alsobe reversed.Zero-InRetune: Shift to Higher Frequency

Page 86 FT-2000D OPERATING MANUALUSING CW REVERSEIf you experience a difficult interference situation, where an interfering station cannot readily be eliminated, you may wishto try receiving using the opposite sideband. This may throw the interfering station’s frequency in a direction that may lenditself more readily to rejection.1. To start, let’s use a typical example where you have setthe CW mode (using the default “USB” injection) ontothe Main (VFO-A) receiver.2. Now be sure your mode selection isstill set for the Main (VFO-A) regis-ter, and press the [CW] mode buttononce more. The “LSB” LED willblink for three seconds, indicatingthat the “LSB” injection side has nowbeen selected.3. When using Dual Receive, press the[B] button, then (within five secondsof pressing the [B] button) press the[CW] button to engage CW Reverseon the Sub (VFO-B) receiver, in ex-actly the same way as for the Main (VFO-A) receiver.4. Press the [CW] mode button once more to return tothe normal (USB) injection side and cancel CW Re-verse operation (the “USB” LED will blink for threeseconds).NOTES:When CW Reverse is engaged, the Tuning Offset In-dicator action will concurrently be reversed as to itsindication.When the incoming signal pitch tone is properlyaligned, the central red marker lights up whether ornot CW Reverse is engaged.CW CONVENIENCE FEATURESIn the illustration, Figure A demonstrates the nor-mal CW injection setup, using the USB side.

Page 87FT-2000D OPERATING MANUALCW CONVENIENCE FEATURESCW DELAY TIME SETTINGDuring semi-break-in (not QSK) operation, the hang time of the transmitter, after you have finished sending, may beadjusted to a comfortable value consistent with your sending speed. This is the functional equivalent to the “VOX Delay”adjustment used on voice modes, and the delay may be varied anywhere between 20 milli-seconds ([DELAY] knob set fullycounter-clockwise) and 5 seconds (fully clockwise).1. Press the [BK-IN] button to enable CW transmission(Menu item “058 A1A BK-IN” must be set to “SEni”).2. Start sending, and adjust the [DELAY] knob so thatthe hang time is as you prefer for comfortable opera-tion.CW PITCH ADJUSTMENTRotation of the front panel’s [PITCH] knob will allowadjustment of the center frequency of the receiver pass-band, as well as the pitch of your offset CW carrier, to thetone you prefer. The tone may be varied between 300 Hzand 1050 Hz, in 50 Hz steps.ADVICE:You may confirm the Spot tone frequency when turningthe [PITCH] knob while pressing the [SPOT] button. Sub(VFO-B) frequency display will shows the Spot tone fre-quency.TERMINOLOGY:CW Pitch: If you tuned to an exact “zero beat” on anincoming CW signal, you could not copy it (“Zero beat”implies a 0 Hz tone). Therefore, the receiver is offset sev-eral hundreds of Hz (typically), so as to allow your ear todetect the tone.
