297 BASIC COMMUNICATIONSAM TRANSMISSIONEach mode used on the HF Amateur bands has itsown advantages. Although long distance DXcontacts may be less common while using AM, thesuperior audio quality characteristic of AM operationis one reason why some hams prefer this mode.When looking for others operating on AM, check thefollowing frequencies first:3885 kHz, 7290 kHz, 14286 kHz, 21390 kHz, and29000 ~ 29200 kHzIf necessary, refer to “OPERATING BASICS”,beginning on page 18, for details on how to receive.1 Select an operating frequency.2 Press [FM/ AM/ NAR] to select AM mode.• “AM” appears.3 Press [MIC/ CAR] to activate the MicrophoneGain Adjust.• The current gain level appears.4 Press [SEND], or press and hold Mic [PTT].• The MAIN band LED lights red.• Refer to “VOX” {page 39} for information onautomatic TX/RX switching.5 Speak into the microphone and adjust theMULTI/ CH control so that the calibrated powermeter slightly reflects your voice level.• Speak in your normal tone and level of voice.Speaking too close to the microphone or tooloudly may increase distortion and reduceintelligibility at the receiving end.• You may want to use the Speech Processor.Refer to “SPEECH PROCESSOR” {page 40}for details.6 Press [SEND] or release Mic [PTT] to return toreceive mode.• The MAIN band LED lights green or turns off,depending on the MAIN SQL setting.7 Press [MIC/ CAR] to quit the Microphone GainAdjust.Refer to “COMMUNICATING AIDS”, beginning onpage 37, for information on additional usefuloperation functions.Note: If necessary, adjust the carrier level before speaking into themicrophone. Press [FUNC], [MIC/ CAR] to enter the adjustmentmode. While transmitting only carrier signals, turn the MULTI/ CHcontrol so that the ALC meter just begins to indicate. Press [FUNC],[MIC/ CAR] again to complete the adjustment.NARROW BANDWIDTH FOR FMWhen operating in FM mode, you can select wide ornarrow bandwidth operation. The table below showsthe RX IF filter bandwidth and TX deviationcombination for each operating mode. Thebandwidth selection is crucial to avoid audio distortionor insufficient intelligibility that the other station willencounter.edoM retliFFIXR noitaiveDXTMF ediW ediWNMF worraN 1 worraN1 K-type: Main transceiver only.All E-types: Main transceiver and sub-receiver.1 Press [FM/ AM/ NAR] to select FM mode.2 Press [FUNC], [FM/ AM/ NAR] to toggle theselection between Wide and Narrow.• “FM” or “FMN” appears to indicate whichbandwidth is selected.NARROW BANDWIDTH FOR AMWhen receiving AM on the main transceiver, you canfurther decrease the bandwidth to eliminateinterference.
