7 BASIC COMMUNICATIONS30CW 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 42}.If necessary, refer to “OPERATING BASICS”,beginning on page 18, for details on how to receive.1 Select the operating frequency.2 Press [CW/ FSK/ REV] to select CW mode.• “CW” appears.• To precisely tune in another station, use AutoZero-beat. Refer to “AUTO ZERO-BEAT”{below}.3 Press [SEND].• The MAIN band LED lights red.• Refer to “CW BREAK-IN” {page 42} forinformation on automatic TX/ RX switching.4 Begin sending.• As you transmit, you should hear a sidetonethat lets you monitor your own transmission.Refer to “TX SIDETONE/ RX PITCHFREQUENCY” {below}.5 Press [SEND] to return to receive mode.• The MAIN band LED lights green or turns off,depending on the MAIN SQL setting.Note: You may adjust the carrier level when necessary. Press[FUNC], [MIC/ CAR] to enter the adjustment mode. With the keydown, turn the MULTI/ CH control so that the ALC meter reads withinthe ALC zone but does not exceed the upper ALC zone limit. Press[FUNC], [MIC/ CAR] again to complete the adjustment.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.1 Press [FUNC], [RIT/ CW TUNE] to start AutoZero-beat.• “CW TUNE” appears.• Your transmit frequency automatically changesso that the pitch of the received signal exactlymatches the TX sidetone/ RX pitch frequencythat you have selected. Refer to “TXSIDETONE/ RX PITCH FREQUENCY” {below}.• When matching is completed, “CW TUNE”disappears.• If matching is unsuccessful, the previousfrequency is restored.2 To quit Auto Zero-beat, press [FUNC],[RIT/ CW TUNE] or [CLR].Note:uYou cannot start Auto Zero-beat if you have selected 1.0 kHz orwider for the DSP filter bandwidth.uWhen using Auto Zero-beat, the matching error is within ±50 Hzin most cases.uAuto Zero-beat may fail if the keying speed of the target station istoo slow or when some interference is present.uWhen RIT function is ON, only RIT frequencies change to makethe Auto Zero-beat adjustment.TX SIDETONE/ RX PITCH FREQUENCYAs you send CW, you will hear tones from thetransceiver speaker. These are called transmit (TX)sidetones. Listening to these tones, you can monitorwhat you are transmitting. You may also use thetones to ensure that your key contacts are closing,the keyer is functioning, or to practice sending withoutactually putting a signal on the air.Receive pitch refers to the frequency of CW that youhear after tuning in a CW station.On this transceiver, the frequency of the sidetone andreceive pitch are equal and selectable. Access MenuNo. 31 to select the frequency that is mostcomfortable for you. The selectable range is from400 Hz to 1000 Hz in steps of 50 Hz.To change the volume of the TX sidetone, accessMenu No. 13. The selections range from 1 to 9 andOFF.Note: The position of the MAIN AF and SUB AF controls do notaffect the volume of the TX sidetone.
