1INSTALLATIONMOBILE INSTALLATIONWhen you use this transceiver for mobile operation, do not attempt to perform any kind of configuration or menusetup configuration while driving your car; it is simply too dangeous. Stop the car and then perform transceiverconfiguration. In addition, do not wear headphones while driving.You should install the transceiver in a safe and convenient position inside your vehicle so as not to subjectyourself to danger while driving. For example, install the transceiver under the dash in front of the passenger seatso that knees or legs will not strike the transceiver if you brake suddenly. Additionally, do not install thetransceiver and its accessories on to the air bag lids. We recommend you consult your car dealer for thetransceiver installation to ensure safety.INSTALLATION EXAMPLE1Attach the 2 L-brackets using the 6 supplied SEMS screws (M4 x 10 mm) as shown below.2Position the transceiver in the mounting bracket and tighten the 4 supplied tapping screws (5 mm x 16 mm) tofix the transceiver in place.Do not install the TX/ RX unit in non-ventilated areas.

21 INSTALLATIONANTENNA CONNECTIONIn general, HF/ 50 MHz mobile antennas are larger and heavier than VHF/ UHF antennas. Therefore, use astrong and rigid mount to safety and securely install the HF/ 50 MHz mobile antenna.A bumper mount is recommended for stable mounting. However, most recent models of vehicles have plasticbumpers. For such vehicles, ground the antenna mount to the body chassis with a large wire. Antennainstallation is critical for successful mobile operation. For further information, refer to The Radio Amateur’sHandbook, Radio Handbook, or other published texts.GROUND CONNECTIONThe ground, which is the other half of the antenna system, is very important when using a mobile whip typeantenna. Connect the feed line ground for the antenna securely to the vehicle’s chassis, and be certain to bond(electrically connect) the vehicle’s body to chassis. The sheet metal will provide the primary ground plane, so besure to establish a good RF connection from the feed line to both the chassis and the body. For comprehensiveinformation on mobile antennas installations and optimization, refer to the ARRL Handbook or similar publications.IGNITION NOISEThis transceiver has been equipped with a Noise Blanker and Digital Noise Limitter to filter ignition noises out.However, some cars may generate excessive ignition noise. If there is excessive noise, use suppressor sparkplugs (with resisters), and/ or DC line filters to reduce the electric noises. The ARRL Handbook, or similarrefereneces, has a wealth of information regarding this topic.Note:◆After installation and wiring are completed, confirm that all work has been done correctly, then connect the DC power cable plug(s) to thetransceiver.◆If the fuse blows, disconnect the DC power cable plug(s) from the transceiver immediately, then check all the DC power cables to find thereasons of the short circuit. The DC cable may be damaged, short circuited, pinched, or squashed. After resolving the problem, replace thefuse with one of the same type and rating.◆Do not remove the fuse holder for any reason.DC13.8V1DC 2 13.8VATGNDGND22112 V batteryDC INRed (+)Black (—)PassengerCompartmentEngine compartment Place the DC cable the wall of the engine compartment securely.

Do not usethe cigarette lighter socket! The current rating of thecigarette lighter socket is too small to operate thetransceiver. Ensure to use a 12 V vehicle batterywhich has sufficient current capacity. If the current isinsufficient, the display may darken duringtransmission or the trasceiver may workintermittiently. If you use the transceiver for a longperiod when the vehicle battery has not been fullycharged or when the engine has been stopped, thebattery may become discharged in a short time andwill not have sufficient reserves to start the engine.Avoid using the transceiver under these conditions.Keep in mind that the TS-480SAT transceiver draws apeak current of approximately 20.5 A and theTS-480HX transceiver draws a peak current ofapproximately 41 A during transmission.Note:◆Do not use two separate batteries to connect each DC cablesfrom the transceiver (TS-480HX). The DC voltage differencebetween DC IN 1 and DC IN 2 connectors at the transceiver mustbe within DC 1.0 V to operate the transceiver.◆Do not use two different type of the cables. Using different lengthand/ or different gauged cable could result in a voltage differencebetween DC IN 1 and DC IN 2 connectors at the transceiver.TS-480SATTS-480HX
31 INSTALLATIONFIXED STATION INSTALLATIONWhen you use the transceiver at a fixed location, the transceiver requires 13.8 V DC power supply(The TS-480HX requires 2 DC power supplies).FRONT PANEL INSTALLATION1Attach the oval-shaped base to the front panel mounting bracket using two SEMS screws (3 mm x 5 mm) asshown below.2Slide the Remote Control panel along the mounting bracket rails until secure.DC POWER SUPPLY CONNECTIONIn order to use this transceiver, you need a separate 13.8 V DC power supply (two 13.8 V DC power supplies arerequired to transmit for the TS-480HX) that must be purchased separately. Do not directly connect the transceiverto an AC outlet. Use the supplied DC power cables to connect the transceiver to a regulated power supply. Donot substitute a cable with smaller gauge wires. The current capacity of each power supply must be 20.5 A peakor more.1Connect the DC power cable(s) to the regulated DC power supply (two 13.8 V DC power supplies are used forthe TS-480HX); the red lead to the positive terminal and the black lead to the negative terminal.2Connect the DC power cable to the transceiver’s DC power connector.• Press the connectors firmly until the locking tab clicks.Note:◆Before connecting the DC power supply to the transceiver, be sure to switch OFF the DC power supply and the transceiver.◆Do not plug the DC power supply into an AC outlet until you make all connections.◆When two power supplies are used for the TS-480HX, the DC voltage difference at the transceiver DC IN connectors must be within 1.0 V DC.◆Do not use different types (length and gauge) of DC cables to avoid voltage differences (TS-480HX).DC13.8V1DC 2 13.8VATGNDGND221Black (—)Red (+)Fuse (25 A)DC IN 1DC 13.8 VDC Power supply (20.5 A or more) DC13.8V1DC 2 13.8VATGNDGND21Black (–)Red (+)Fuse (25 A)DC IN 1DC 13.8 VDC IN 2DC 13.8 VRed (+)Fuse (25 A)DC Power supply(20.5 A or more)DC Power supply(20.5 A or more)TS-480SAT TS-480HX
41 INSTALLATIONANTENNA CONNECTIONAn antenna system consists of an antenna, feed line, and ground. The transceiver can give excellent results if theantenna system and its installation are given careful attention. Use a properly adjusted 50 Ω antenna of goodquality, a high-quality 50 Ω coaxial cable, and first-quality connectors. All connections must be clean and tight.After making the connections, match the impedance of the coaxial cable and antenna so that the SWR is 1.5:1 orless. High SWR will cause the transmit output to drop and may lead to radio frequency interference to consumerproducts such as stereo receivers and televisions. You may even interfere with your own transceiver. Reportsthat your signal is distorted could indicate that your antenna system is not efficiently radiating the transceiver’spower.Connect your primary HF/ 50 MHz antenna feed line to ANT 1 on the rear of the transceiver. If you are using twoHF/ 50 MHz antennas, connect the secondary antenna to ANT 2. Refer to page 16 for the location of the antennaconnectors.Note:◆Transmitting without connecting an antenna or other matched load may damage the transceiver. Always connect the antenna to thetransceiver before transmitting.◆All fixed stations should be equipped with a lightning arrester to reduce the risk of fire, electric shock, and transceiver damage.◆The transceiver’s protection circuit will activate when the SWR is greater than 2.5:1; however, do not rely on protection to compensate for apoorly functioning antenna system.GROUND CONNECTIONAt the minimum, a good DC ground is required to prevent such dangers as electric shock. For superiorcommunications results, a good RF ground is required against which the antenna system can operate. Both ofthese conditions can be met by providing a good earth ground for your station. Bury one or more ground rods ora large copper plate under the ground, then connect this to the transceiver GND terminal. Use heavy gauge wireor a copper strap, cut as short as possible, for this connection. Do not use a gas pipe, an electrical conduit, or aplastic water pipe as a ground.LIGHTNING PROTECTIONEven in areas where lightning storms are less common, there are usually a limited number of storms each year.Consider carefully how to protect your equipment and home from lightning. The installation of a lightning arrestoris a start, but there is more that you can do. For example, terminate your antenna system transmission lines at anentry panel that you install outside your home. Ground this entry panel to a good outside ground, then connectthe appropriate feed lines between the entry panel and your transceiver. When a lightning storm occurs,disconnecting the feed lines from your transceiver will ensure additional protection.

As for HF and the 6 m band,29 MHz and 51-54 MHz bands are commonly usedfor FM operation. You can also utilize 10 m/ 6 m bandrepeaters to reach your friends when they are outsideor skipped over from your coverage. Although FMrequires a wider bandwidth when compared to SSBor AM mode, it has the finest audio quality amongthese modes. When combined with the full-quietingaspect of FM signals, which suppress backgroundnoise on the frequency, FM can be the best methodfor maintaining casual communications with yourlocal friends.If necessary, refer to “OPERATING BASICS”,beginning on page 18, for details on how to receive.1Select an operating frequency.2Press [MODE] until “FM” appears.• If “FM” does not appear, select “AM”, thenpress [MODE] (1 s).

296 BASIC COMMUNICATIONSCW TRANSMISSIONCW operators know that this mode is very reliablewhen communicating under worst conditions. It maybe true that newer digital modes rival CW as beingequally as useful in poor conditions. These modes,however, do not have the long history of service northe simplicity that CW provides.This transceiver has a built-in electronic keyer thatsupports a variety of functions. For details on usingthese functions, refer to “ELECTRONIC KEYER”{page 39}.If necessary, refer to “OPERATING BASICS”,beginning on page 18, for details on how to receive.1Select the operating frequency.2Press [MODE] until “CW” or “CWR” appears.• To precisely tune in another station, use AutoZero-beat. Refer to “AUTO ZERO-BEAT”{below}.3Press [VOX/ 8] to activate the CW break-infunction.• “VOX” appears.• Refer to “CW BREAK-IN” for further informationon automatic TX/ RX switching {page 39}.4Begin sending the message.• As you transmit, you should hear a sidetonethat lets you monitor your own transmission.• The LED lights red as you send the message.5Stop sending the message to return to Receptionmode.• The LED lights green or turns off, dependingon the SQL control setting.AUTO ZERO-BEATUse Auto Zero-beat before transmitting to tune in aCW station. Auto Zero-beat automatically and exactlymatches your transmit frequency with the station youare receiving. Neglecting to do this will reduce yourchances of being heard by the other station.1Tune to the CW signal using the Tuning control.2Press [BC/ CW.T] (1 s) to start Auto Zero-beatwhile CW is selected for the operating mode.• “CW TUNE” appears.• Your reception frequency automaticallychanges so that the pitch (tone) of the receivedsignal exactly matches the TX sidetone/ RXpitch frequency that you have selected. Referto “TX SIDETONE/ RX PITCH FREQUENCY”{below}.• When matching is completed, “CW TUNE”disappears.• If matching is unsuccessful, the previousfrequency is restored.3To quit Auto Zero-beat, press [CLR/ MTR] orpress [BC/ CW.T] again.Note:◆You cannot start Auto Zero-beat if you have selected 1.0 kHz orwider for the DSP filter bandwidth {page 46}.◆When using Auto Zero-beat, the matching error is within ±50 Hzin most cases.◆Auto Zero-beat may fail if the keying speed of the target station istoo slow or some interference is present.◆When the RIT function is ON, only RIT frequencies change tomake the Auto Zero-beat adjustment.TX SIDETONE/ RX PITCH FREQUENCYAs you send CW, you will hear tones from thetransceiver speaker. These are called TX(transmission) sidetones. Listening to these tones,you can monitor what you are transmitting. You mayalso use the tones to ensure that your key contactsare closing, the keyer is functioning, or to practicesending without actually putting a signal on the air.RX (reception) pitch refers to the frequency of CWthat you hear after tuning in a CW station.On this transceiver, the frequency of the sidetone andRX pitch are equal and selectable. Access Menu No.34 to select the frequency that is most comfortable foryou. The selectable range is from 400 Hz to 1000 Hzin steps of 50 Hz (default is 800 Hz).To change the volume of the TX sidetone, accessMenu No. 13. The selections range from 1 to 9 andOFF (default is 5).Note: The position of the AF control does not affect the volume ofthe TX sidetone.
ENHANCED COMMUNICATIONS30SPLIT-FREQUENCY OPERATIONUsually you can communicate with other stationsusing a single frequency for receiving andtransmitting. In this case, you select only onefrequency on either VFO A or VFO B. However, thereare cases where you must select one frequency forreceiving and a different frequency for transmitting.This requires the use of 2 VFOs. This is referred toas “split-frequency operation”. One typical casewhich requires this type of operation is when you usean FM repeater {page 31}. Another typical case iswhen you call a rare DX station.When a rare or desirable DX station is heard, thatoperator may immediately get many simultaneousresponses. Often, such a station is lost under thenoise and confusion of many calling stations. If youfind that you are suddenly being called by manyoperators, it is your responsibility to control thesituation. You may announce that you will be “listeningup 5 (kHz, from your present transmission frequency)”,or “listening down between 5 and 10 (kHz)”.1Press [A/B / M/V] to select VFO A or VFO B toreception frequency.•“tA” or “tB” appears to show which VFO isselected.2Select an operating frequency.• The frequency selected at this point will beused for transmission.• To copy the selected VFO frequency to theother VFO, press [A=B/ SPLIT].3Press [A/B / M/V] to select the other VFO.4Select an operating frequency.• The frequency selected on this VFO will beused for reception.5Press [A=B/ SPLIT] (1 s).•“ ” appears.• Each time you press [A/B / M/V], the receptionand the transmission frequency are swapped.6To quit split-frequency operation, press[A=B/ SPLIT] (1 s) again.•“ ” disappears.TF-SET (TRANSMISSION FREQUENCY SET)TF-SET allows you to temporarily switch yourtransmission frequency and reception frequency.Canceling this function immediately restores theoriginal transmission and reception frequencies.By activating TF-SET, you can listen on yourtransmission frequency, and change it while listening.This allows you to check whether or not the newlyselected transmission frequency is free of interference.1Configure split-frequency operation as explainedin the previous section.2Press [MENU/ F.LOCK] (1 s) to lock the Tuningcontrol.•“” appears.3Press and hold either [ ] or [ ] while the “ ”icon is visible. While holding down [ ] or [ ],turn the Tuning control or press Mic [UP]/ [DWN]to change the transmission frequency.• The transceiver receives on the frequency asyou change, but the frequency shown on thesub-display (the original reception frequency)stays unchanged.4Release [ ] or [ ].• You are now receiving again on your originalreception frequency.Successfully contacting a DX station in a pileup oftendepends on making a well-timed call on a clearfrequency. That is, it is important to select a relativelyclear transmission frequency and to transmit at theexact instant when the DX station is listening but themajority of the groups aren’t transmitting. Switchyour reception and transmission frequencies by usingthe TF-SET function and listen to your transmissionfrequency. You will soon learn the rhythm of the DXstation and the pileup. The more proficient youbecome at using this function, the more DX stationsyou will contact.Note:◆TF-SET is disabled while transmitting.◆An RIT offset frequency is not added; however, an XIT offsetfrequency is added to the transmission frequency.
317 ENHANCED COMMUNICATIONSFM REPEATER OPERATIONMost Amateur radio voice repeaters use a separatereception and transmission frequency. Thetransmission frequency may be higher or lower thanthe reception frequency. In addition, some repeatersmay require the transceiver to transmit a subtonebefore the repeater can be used.Compared to simplex communication, you canusually transmit over much greater distances byusing a repeater. Repeaters are typically located ona mountain top or other elevated location. Often theyoperate at higher ERP (Effective Radiated Power)than a typical station. This combination of elevationand high ERP allows communications overconsiderable distances.HF/ 6 m band repeaters operate usually in the29 MHz FM sub-band and 51-54 MHz band. Thisspecial service combines the advantages of FMoperation, good fidelity with noise and interferenceimmunity, with the excitement of HF DX (longdistance) communications.

327 ENHANCED COMMUNICATIONSTRANSMITTING A TONEIn general, FM repeaters require the transceiver totransmit a sub-audible tone to prevent otherrepeaters on the same frequency from locking eachother up. The required tone frequency differs amongrepeaters. Repeaters also differ in their requirementsfor either continuous or burst tones. For theappropriate selections for your accessible repeaters,consult your local repeater reference.After completing the tone settings, pressing andholding Mic [PTT] causes the transceiver to transmitthe selected tone. If you have selected a 1750 Hztone, the transceiver sends a 500 ms tone burst eachtime transmission starts.Note: If you store tone settings in a memory channel, you need notreprogram each time. Refer to “MEMORY FEATURES” {page 50}.■Activating the Tone Function1Confirm that FM mode has been selected onthe VFO(s) {page 19}.• When using 2 VFOs, you must select FMmode on both VFOs.2Press [NB/T/ 7].• “T” appears.Note: You cannot use the Tone function with the CTCSSfunction.■Selecting a Tone Frequency1While “T” appears (Tone function is ON), press[NB/T/ 7] (1 s).• The current tone frequency appears.The default is 88.5 Hz.2Turn the MULTI control to select the desiredtone frequency.• The available tone frequencies are listed inthe following table.3Press [MTR/ CLR] to complete the setting..oN .qerF )zH( .oN .qerF )zH( .oN .qerF )zH( .oN .qerF )zH(000.76114.79223.141335.602103.96210.001322.641437.012209.17315.301424.151531.812304.47412.701527.651637.522400.77519.011622.261731.922507.97618.411729.761836.332605.28718.811828.371938.142704.58810.321929.971043.052805.88913.721032.681141.452905.19028.131138.291240571018.49125.631235.302Note:◆You can select a tone frequency independent of a CTCSSfrequency.◆When 1750 Hz is selected, the transceiver sends a 500 mstone burst each time transmission starts.

COMMUNICATING AIDS34RECEPTIONSELECTING YOUR FREQUENCYIn addition to turning the Tuning control or pressingMic [UP]/ [DWN], there are several other ways toselect your frequency. This section describesadditional methods of frequency selection that maysave you time and effort.■Direct Frequency EntryWhen the desired frequency is far removed fromthe current frequency, directly entering afrequency from the numeric keypad is usually thefastest method.1Press [ENT].• “ - - . - - - . - - ” appears.2Press the numeric keys ([0] to [9]) to enteryour desired frequency.• Pressing [ENT] at any time fills theremaining digits (the digits you did notenter) with 0 and completes the entry.To select 1.85 MHz for example, press[ENT], [0], [1], [8], [5], then press [ENT] tocomplete the input (6 key strokes).• Pressing [MTR/ CLR] before pressing[ENT] cancels the entry and restores thecurrent VFO frequency.Note:◆You can enter a frequency in the range of 30.00 kHz to59.999.99 MHz. Refer to the specifications for theavailable frequency range.◆Attempting to enter a frequency that is outside theselectable frequency range causes an alarm to sound.The entered frequency is rejected.◆When the entered frequency does not meet the currentVFO frequency step size requirement, the nearestavailable frequency is automatically selected after theentered frequency is changed.◆When the 10 Hz digit (last displayed digit) is entered, thedigit 0 is automatically entered for the 1 Hz digit, andfrequency entry is completed. The 1 Hz digit is notdisplayed.◆When an entered frequency is accepted, RIT or XIT will beswitched OFF, but the RIT or XIT offset frequency is notcleared.■Using the MHz keyPressing [ ]/ [ ] on the Remote Control panelchanges Amateur bands. You can also use theMULTI control to change the operating frequencyin steps of 1 MHz.1Press [MHz].• “MHz” appears.2Turn the MULTI control.• Clockwise increases the frequency andcounter-clockwise decreases the frequency.3Press [MHz] again to exit.• “MHz” disappears.If you prefer to change the frequency in steps of100 kHz or 500 kHz rather than 1 MHz, press[MHz] (1 s), then turn the MULTI control to select100 kHz, 500 kHz, or 1 MHz.Note: Even if 100 kHz or 500 kHz is assigned for the [MHz] key,“MHz” appears on the display.■Quick QSYTo move up or down the frequency quickly, use theMULTI control. Turning this control changes theoperating frequency in steps of 5 kHz for SSB/CW/ AM/ FSK and 10 kHz for FM.• If you want to change the default frequencystep size, press [FINE/ STEP] (1 s). Turn theMULTI control to select 5 kHz, 6.25 kHz, 10kHz, 12.5 kHz, 15 kHz, 20 kHz, 25 kHz, 30kHz, 50 kHz or 100 kHz for FM/ AM, and 500Hz, 1 kHz, 2.5 kHz, 5 kHz, or 10 kHz for theother modes. The default step size is 5 kHz forSSB/ CW/ FSK/ AM and 10 kHz for FM.• When changing the operating frequency byusing the MULTI control, frequencies arerounded such that new frequencies aremultiples of the frequency step size. To disablethis function, access Menu No. 05 and select“oFF” (default is “on”).• Within the AM broadcast band, the step sizeautomatically defaults to the frequency stepvalue in Menu No. 06. This step size can beswitched between 9 kHz (all E-types: “on”) and5 kHz (K-type: “oFF”) via Menu No. 06.Note: The programmed frequency step size for the MULTIcontrol is stored independently for the HF and 50 MHz bands.You can also set a different frequency step size for SSB/ CW/FSK, AM and FM modes.■Configuring the Tuning Control as MULTI control(FM)In FM mode, you can configure the Tuning controlto change the frequency as same as the MULTIcontrol. Access Menu No. 04 and select “on”(default is “oFF”). O yu turn the Tuning control,the frequency changes as same as turning theMULTI control.
358 COMMUNICATING AIDS■Fine TuningThe default frequency step size when turning theTuning control to change the frequency is 10 Hzfor SSB, CW, and FSK modes, and 100 Hz for FMand AM modes. However, you can change thefrequency step size to 1 Hz for SSB, CW, and FSKmodes, and 10 Hz for FM and AM modes.1Press [FINE/ STEP].• “FINE” appears.2Turn the Tuning control to select the exactfrequency.3To quit the function, press [FINE/ STEP] again.• “FINE” disappears.■Tuning control adjustment rateThe default Tuning control adjustment rate is“500”. This represents the number of pulses theTuning control generates in a complete revolution.Each pulse changes the tuning frequency basedon the current frequency step size (the frequencystep size for the Tuning control is 10 Hz for SSB/CW/ FSK mode and 100 Hz for AM/ FM mode).For example, in SSB mode the freqency step sizeis 10 Hz, so the frequency would change by5,000 Hz in a complete revolution of the Tuningcontrol. The adjustment rate of the Tuning controlcan be lowered to “250” pulses per revolution orincreased to “1000” pulses per revolution.1Press [MENU/ F.LOCK].2Turn the MULTI control to select Menu No. 4.3Press [ ]/ [ ] to select “250”, “500” (default),or “1000”.4Press [MENU/ F.LOCK] to store the settingand exit Menu mode.■Equalizing VFO Frequencies (A=B)This function allows you to copy the frequency andmodulation mode of the active VFO to the inactiveVFO.1Select the frequency and mode on VFO A orVFO B.2Press [A=B/ SPLIT].• The frequency and mode selected in step 1are duplicated to the inactive VFO.3Press [A/B / M/V] to confirm that the frequencywas copied.RIT (RECEIVE INCREMENTAL TUNING)RIT provides the ability to change your receptionfrequency by ±9.99 kHz in steps of 10 Hz withoutchanging your transmission frequency. If the FineTuning ([FINE/ STEP]) function is ON, the step sizebecomes 1 Hz. RIT works equally well with allmodulation modes and while using VFO or MemoryRecall mode.1Press [RIT].•“RIT” and the RIT offset appear.2If required, press [CL] to reset the RIT offset to 0.3Turn the RIT/ XIT control to change your receptionfrequency.4To turn RIT OFF, press [RIT].• The reception frequency is returned to thefrequency that was selected prior to step 1.Note: When storing the frequency in a Memory channel with the RITfunction ON, the RIT offset frequency is added or subtracted to/ fromthe VFO frequency. The calculated data is then stored in the Memorychannel.AGC (AUTOMATIC GAIN CONTROL)When using a mode other than FM, AGC selects thetime constant for the Automatic Gain Control circuit.Selecting a slow time constant will cause the receivergain and S-meter readings to react slowly to largeinput changes. A fast time constant causes thereceiver gain and the S-meter to react quickly tochanges in the input signal. A fast AGC setting isparticularly useful in the following situations:• Tuning rapidly• Receiving weak signals• Receiving high-speed CWFor your convenience, the following default AGC timeconstant has already been programmed.SSB: Slow (“AGC”) CW: Fast (“AGC - F”)FSK: Fast (“AGC - F”) AM: Slow (“AGC”)To change the default time constant:1Press [AGC/ 0/ OFF].• The AGC time constant icon appears on thedisplay (“AGC”: Slow, “AGC - F”: Fast).• Each time you press [AGC/ 0/ OFF], the AGCtime constant alternates fast and slow.2If you want to turn the AGC OFF, press[AGC/ 0/ OFF] (1 s).• “AGC OFF” appears on the display.Note: You cannot adjust the AGC time constant in FM mode.
368 COMMUNICATING AIDSTRANSMISSIONVOX (VOICE-OPERATED TRANSMIT)VOX eliminates the necessity of manually switchingto the transmission mode each time you want totransmit. The transceiver automatically switches totransmission mode when the VOX circuitry sensesthat you have begun speaking into the microphone.When using VOX, develop the habit of pausingbetween thoughts to allow the transceiver to dropback to reception mode briefly. You will then hear ifanybody wants to interrupt, plus you will have a shortperiod to gather your thoughts before speaking again.Your listeners will appreciate your consideration aswell as respect your more articulate conversation.VOX can be switched ON and OFF independently forCW and the other modes, excluding FSK.Press [VOX/ 8] to toggle between VOX ON and OFF.• “VOX” appears when the VOX function is ON.■Microphone Input LevelTo enjoy the VOX function, take the time toproperly adjust the gain of the VOX circuit. Thislevel controls the capability of the VOX circuit todetect the presence or absence of your voice.In CW mode, this level cannot be adjusted.1Select USB, LSB, FM, or AM mode.2Press [VOX/ 8] to switch the VOX function ON.• “VOX” appears.3Press [VOX/ 8] (1 s).• The current VOX gain appears on the sub-display.4While speaking into the microphone using yournormal tone of voice, adjust the setting (defaultis 4) using the MULTI control until thetransceiver reliably switches to transmissionmode each time you speak.• The selectable gain range is from 0 to 9.• The setting should not allow backgroundnoise to switch the transceiver to transmitmode.Note: The VOX gain level can be adjusted even if VOX isswitched OFF or while you are transmitting.■Delay TimeIf the transceiver returns to reception mode tooquickly after you stop speaking, your final wordmay not be transmitted. To avoid this, select anappropriate delay time that allows all of yourwords to be transmitted without an overly longdelay after you stop speaking.1Select USB, LSB, FM, or AM mode.2Press [VOX/ 8] to switch the VOX function ON.• “VOX” appears.3Press [KEY/ DELAY] (1 s).• The current setting appears on the sub-display. The default is 50 (1500 ms).4While speaking into the microphone using yournormal tone of voice, turn the MULTI controlsuch that the transceiver switches to receptionmode after you have stopped talking.• The selectable range is from 5 to 100(150 ms to 3000 ms) in steps of 5, or OFF.5Press [MTR/ CLR] to store the parameter andexit the setting mode.■Anti-VOX adjustmentThe TS-480 transceiver has a DSP IC to improveand customize incoming/ outgoing audio signals.When VOX function is turned ON, the DSP ICadjusts the Anti-VOX level automatically,comparing the reception sound level andmicrophone input level. So, you never have toworry about adjusting the anti-VOX level.■VOX SourceAlthough microphone is normally used to performthe VOX transmission, you can also utilize AFinput of the DATA connector (pin 1) on the TX/ RXunit {page 81}. When the transceiver detects theaudio signal on the pin 1 of DATA connector, thetransceiver automatically transmits.1Select USB, LSB, FM, or AM mode.2Press [VOX/ 8] to switch the VOX function ON.• “VOX” appears.3Press [MENU/ F.LOCK] and turn MULTIcontrol to select Menu No. 60.4Press [ ] to switch the VOX with DATA inputfunction ON.5Turn MULTI control to select Menu No. 46.6While sending AF signal to pin 1 of DATAconnector, adjust the value (default is 4) using[ ]/ [ ] until the transceiver reliably switchesto transmit mode each time you send AF signalto pin 1 of DATA connector.Note: VOX function does not work even if you speak into themicrophone. However, you can transmit with the Mic [PTT].
378 COMMUNICATING AIDSSPEECH PROCESSORThe Speech Processor levels out large fluctuations inyour voice while you speak. When using SSB, FM, orAM mode, this leveling action effectively raises theaverage TX power, resulting in a moreunderstandable signal. The amount of voicecompression is fully adjustable. You will notice thatusing the Speech Processor makes it easier to beheard by distant stations.1Select USB, LSB, FM, or AM mode.2Press [PROC/ 9] to turn the Speech ProcessorON.• “PROC” appears.3Press [PROC/ 9] (1 s) to enter the SpeechProcessor input level adjustment mode.4As you speak into the microphone, turn theMULTI control so that the compression meterindicates that the compression level is around10 dB while you speak.• Using higher compression will not improve yoursignal clarity or apparent signal strength.Excessively compressed signals are moredifficult to understand due to distortion and areless pleasant to hear than signals with lesscompression.5Press [PROC/ 9] (1 s) to exit the SpeechProcessor input level adjustment mode.6Press [MIC/ 5/ RF.G] to enter the SpeechProcessor output level adjustment mode.• As you speak into the microphone, turn theMULTI control so that the ALC meter reflectsaccording to your voice level but does notexceed the ALC limit. Press [MIC/ 5/ RF.G] toexit when you finish the adjustment mode.XIT (TRANSMIT INCREMENTAL TUNING)Similar to RIT, XIT provides the ability to change yourtransmission frequency by ±9.99 kHz in steps of 10 Hzwithout changing your reception frequency. If the FineTuning function is ON, the frequency step sizebecomes 1 Hz.1Press [XIT].• “XIT” and the XIT offset appear.2If required, press [CL] to reset the XIT offset to 0.3Turn the RIT/ XIT control to change your transmitfrequency.4To turn XIT OFF, press [XIT].• “XIT” and offset frequency display disappear.The transmission frequency is returned to thefrequency that was selected prior to step 1.Note:◆If the Fine Tuning function is ON, you can adjust the frequencywithin ±9.99 kHz.◆The frequency shift set by the XIT control is also used by the RITfunction. Therefore, changing or clearing the XIT offset alsoaffects the RIT offset.◆When the XIT frequency exceeds the limit of availabletransmission frequency, the transceiver automatically stopstransmitting.TX powerTX powerTimeTimeSpeech Processor OFFSpeech Processor ON

418 COMMUNICATING AIDS■Changing the Inter-message Interval TimeFor the message playback repeat, access MenuNo. 31 and select “on”. You can also change theinterval playback time of the message. AccessMenu No. 32 and select the time in the range of 0to 60 seconds in steps of 1 second.Note: Menu Nos. 31 and 32 settings are shared with the voicecommunication modes when the optional VGS-1 is installed.■Changing the Sidetone VolumeTurning the AF control does not change the CWsidetone playback volume. To change the CWsidetone volume, access Menu No. 13 and select“oFF”, or “1” to “9”.■Insert KeyingIf you operate a CW keyer manually while playingback a recorded CW message, the transceiverstops playing back the message. However, duringcontests or regular QSOs, you may sometimeswant to insert a different number or message at acertain point in the recorded message.In this case, first record the CW message as usual{page 40}, without the number or message youwant to insert. Then, access Menu No. 33 andselect “on”.Now if you operate a CW keyer while you playback a recorded message, the transceiver pausesthe playback of the recorded message, instead ofstopping it. When you finish sending the numberor message with the keyer, the transceiverresumes playback of the message.FREQUENCY CORRECTION FOR CWIf you operate both SSB and CW modes, you wouldsometimes use SSB mode (USB or LSB) just towatch and listen to CW signals. It is fine just tomonitor those CW signals but you have experiencedthat changing the mode from SSB to CW results inlosing the target CW signal. This is because thefrequency on the display always shows the truecarrier frequency for all modes. If you want thetransceiver to shift the reception frequency to tracethe receiving CW signal when changing the modefrom SSB (USB or LSB) to CW, switch this functionON. The transceiver shifts the reception frequencywhen changing the mode from SSB to CW, so youcan still hear the target signal and instantly transmitthe signal in CW without adjusting the frequency.1Press [MENU/ F.LOCK], then turn the MULTIcontrol to access Menu No. 40.2Press [ ] to select “on”.3Press [MENU/ F.LOCK] to store the settings andexit the Menu mode.AUTO CW TX IN SSB MODEIf you operate both SSB and CW modes, you canconfigure the transceiver to change the operatingmode from SSB (USB or LSB) to CW and thentransmit in CW mode automatically when you operatethe CW keyers.1Press [MENU/ F.LOCK], then turn the MULTIcontrol to access Menu No. 39.2Press [ ] to select “on”.3Press [MENU/ F.LOCK] to store the settings andexit the Menu mode.Note: You must switch the CW break-in function ON to change themode and transmit in CW mode {page 39}.MIC UP/ DWN KEY PADDLE MODEThis function allows you to send CW messagewithout using an optional paddle {page 7}. Mic [UP]key can be used as dot paddle and Mic [DWN] keycan be used as a dash paddle.To activate Mic UP/ DWN key Paddle Mode:1Turn the transceiver OFF.2Press Mic [UP] or Mic [DWN] + [ ] (POWER).• Press and hold Mic [UP] to send dots or Mic[DWN] to send dashes in CW mode.To exit Mic UP/ DWN key Paddle Mode, perform step1 and 2 again.CW REVERSE (RECEPTION)This function pivots the BFO from the default position(USB) to another position (LSB) in CW mode. It issometimes effective to remove the interfering signalsfrom the IF passband by pivoting the BFO.1Press [MODE] until “CW” appears.2Press [MODE] (1 s).• “CW” changes to “CWR”.3To recover the default BFO position, press[MODE] (1 s) again.• “CWR” changes to “CW”.
42SPECIALIZED COMMUNICATIONSRADIO TELETYPE (RTTY)RTTY is the data communications mode with thelongest history. It was originally designed for use withmechanical teletypewriters which were often usedbefore personal computers became common. Nowyou can easily start operating RTTY with a personalcomputer and MCP. Unlike Packet, each time youtype a letter, it is transmitted over the air. What youtyped is transmitted and displayed on the computerscreen of the recipient.RTTY operation uses frequency shift keying (FSK)and the 5-bit Baudot code or the 7-bit ASCII code totransmit information.For the cable connections, refer to “RTTYOPERATION” {page 80}.For further information, consult reference booksabout Amateur Radio.1Access Menu No. 41 and select an FSK shift.• FSK shift is the difference in frequenciesbetween a mark and a space.• The 170 Hz shift (default) is normally used onthe Amateur bands for the RTTY.2Access Menu No. 42 and select a key-downpolarity.• Select “oFF” (default) to transmit a mark whenkeying down or “on” to transmit a space.3Access Menu No. 43 and select high tone(2125 Hz) or low tone (1275 Hz) for mark.• High tone (default) is commonly usednowadays.4Select an operating frequency.5Press [MODE] to select FSK mode {page 19}.• If necessary, use Menu No. 47 to configure theappropriate audio level from your MCP.The AF control cannot be used to adjust theaudio level from your MCP.6Some stations may be operating in Reverse shift.In this case, press [MODE] (1 s) to reverse theshift (the upper sideband is used).• “FSR” appears.• Traditionally, the lower sideband is used forFSK operation. Press [MODE] (1 s) again toreturn to the lower sideband. “FSK” appears.7Follow the instructions provided with your MCPand enter a command from your computer totransmit.• The LED changes from green (RX) to red (TX).8Begin sending data from your computer.• Press [PWR/ 4/ TX MONI] (1 s) to monitor yoursignals. Press [PWR/ 4/ TX MONI] (1 s) againto quit this function.9When finished transmitting, enter a command fromyour computer to return to reception mode.• The LED changes from red (TX) to green (RX).The following frequencies (measured in kHz)commonly used for RTTY operation:adanaC/.A.S.U 1noigeRURA )acirfA/eporuE(0481~00812481~8381)0953:XD(5463~50630263~0853)0407:XD(0017~08075407~530705101~0410105101~041015.99041~070415.99041~0804101181~0018190181~1018100112~0701202112~0801203942~0294292942~0292205182~0708205182~05082
439 SPECIALIZED COMMUNICATIONSAMTOR/ PacTOR/ CLOVER/ G-TOR/ PSK31Besides RTTY, digital modes which have been usedamong hams include AMTOR, PacTOR, CLOVER, G-TOR, and PSK31. For details, consult referencebooks about the digital mode communications ofamateur radio.AMTOR (AMateur Teleprinting Over Radio) hasbrought amateur HF digital communication into thecomputer age. It is the first error-free HF digital modeby which data bursts (not steady stream of data) aretransmitted.PacTOR (Packet Teleprinting On Radio) hascombined the best features of both AMTOR andPacket to improve the efficiency of HF digitalcommunications. Like Packet and AMTOR, PacTORsends error-free data using a handshaking method.Of all the Amateur Radio HF digital modes, CLOVERoffers the best overall performance using acomplicated modulation technique, automatic poweradjustment and other advanced features. It mayallow communications to be maintained under theworst conditions.G-TOR (Golay-coded Teleprinting Over Radio) is arelatively new Amateur Radio digital mode currently inuse. G-TOR was developed specifically to handle theadverse conditions of communicating across the solarsystem with spacecraft during their missions.PSK31 was developed by an RTTY enthusiast,G3PLX, in the United Kingdom. The operatingtechnique is very similar to the conventional Baudot-RTTY, although more sensitive fine-tuning is required,as a PSK31 signal requires a tuning accuracy of afew Hertz. A special feature of PSK31 is that it allowsthe entire ASCII character set, including the backspace character.Your MCP should handle some or all of the abovemodes. For available modes on your MCP, consultthe instruction manual for the MCP. For the cableconnections, refer to “MCP AND TNC” {page 81}.On most HF bands, audio frequency shift keying(AFSK) is used for the above modes. This method ofmodulation uses audio tones, therefore either LSB orUSB mode should be selected. Traditionally, LSB isused, similar to RTTY, with the exception of AMTORwhich is normally operated in USB.AMTOR activity can be found on or near 14075 kHzand 3637.5 kHz. These are also good starting placeswhen searching for PacTOR, CLOVER, G-TOR, orPSK31 stations.The TS-480 transceiver has special DSP filters forthese digital modes. Refer to page 48 for details.Note: When using SSB mode for digital operation, use a fast AGCsetting and switch your Speech Processor OFF.PACKET RADIOPacket is a unit of data transmitted as a whole fromone computer to another, on a network. Packets canbe transmitted on radio waves as well as oncommunications lines. Besides a transceiver and acomputer, all you need is a terminal node controller(TNC) or Multimode Communications Processor(MCP). One of the tasks of TNCs and MCPs is toconvert data packets to audio tones, and vice versa.Connecting a TNC to this transceiver allows you touse many packet applications.A variety of packet applications developed by hamsinclude packet bulletin board systems (PBBSs).PBBSs are created and maintained by volunteerscalled System Operators (SysOp). You may accessone of your local PBBSs to send e-mail, downloadfiles, or obtain various useful information. Thousandsof PBBSs, which have formed a worldwide network,relay e-mail to their intended destinations around theworld.When you access a local PBBS for the first time, youoften need to register as a new user. After you aresuccessfully registered, it will then be available asyour home PBBS. E-mail addressed to you will beheld under a directory, called a mailbox, on yourhome PBBS.For further information, consult reference bookswhich should be available at any store that handlesAmateur Radio equipment. Web pages relating toPacket will also be helpful. On Internet searchengines, use “Packet Radio” as key words to findthose Web pages.Note:◆Unlike a TNC, a Multimode Communications Processor (MCP)serves as a communications interface in several digital modessuch as Packet, RTTY, and AMTOR. You can cause it to switchamong the modes by sending a single command from yourcomputer.◆If there is an amateur radio club in your area, consider becominga member. You can often learn more in an hour fromexperienced hobbyists, than in a month of independent research.Ask on the local repeaters or contact your national amateur radioorganization (the ARRL in the U.S.A.) for information on localamateur radio clubs. You’ll be glad you did.PBBS
