5 BASIC COMMUNICATIONS SSB TRANSMISSION SSB is the most commonly-used mode on the HF Amateur radio bands. Compared with other voice modes, SSB requires only a narrow bandwidth for communications. SSB also allows long distance communications with minimum transmission power. If necessary, refer to "OPERATING BASICS", beginning on page 10, for details on how to receive. 1 Select an operating frequency. 2 Press [LSB/USB] until "USB" or "LSB" appears on the operating mode display. • If the desired sideband ("USB" or "LSB") does not appear, select the other sideband first. Then, press [LSB/USB]. The mode indicator changes to your desired sideband. • "USB" represents the upper sideband and "LSB" represents the lower sideband. Normally, USB is used for the communications for 10 MHz and above while LSB is used for the frequencies below 10 MHz. 3 Press [MIC (CAR)] to adjust the Microphone gain. • The current gain level appears on the subdisplay. 4 Press and hold Mic [PTT]. • The TX-RX LED lights red. • Refer to "VOX" {page 31} for information on automatic TX/ RX switching. 5 Speak into the microphone and turn the MULTI/CH control so that the ALC meter reflects your voice level but does not exceed the ALC limit. • Speak in your normal tone and level of voice. Speaking too close to the microphone or too loudly may increase distortion and reduce intelligibility at the receiving end. • You may want to use the Speech Processor. Refer to "SPEECH PROCESSOR" {page 32} for details. 6 Release Mic [PTT] to return to Reception mode. • The TX-RX LED lights green or turns off, depending on the SQL control position. 7 Press [MIC (CAR)] or [CLR] to exit the Microphone gain adjustment. Refer to "COMMUNICATING AIDS", beginning on page 29, for information on additional useful operation functions. AM TRANSMISSION Each mode used on the HF Amateur bands has its own advantages. Although long distance DX contacts may be less common while using AM, the superior audio quality characteristic of AM operation is one reason why some hams prefer this mode. If necessary, refer to "OPERATING BASICS", beginning on page 10, for details on how to receive. 1 Select an operating frequency. 2 Press [FM/AM (FM-N)] until "AM" appears. • If "AM" does not appear, select "FM" first, then press [FM/AM (FM-N)]. The mode indicator changes to "AM". 3 Press [MIC (CAR)] to enter the Microphone gain adjustment mode. • The current gain level appears on the subdisplay. 4 Press and hold Mic [PTT]. • The TX-RX LED lights red. • Refer to "VOX" {page 31} for information on automatic TX/ RX switching. 5 Speak into the microphone and adjust the MULTI/CH control so that the power meter slightly reflects your voice level. • Speak in your normal tone and level of voice. Speaking too close to the microphone or too loudly may increase distortion and reduce intelligibility at the receiving end. • You may want to use the Speech Processor. Refer to "SPEECH PROCESSOR" {page 32} for details. 6 Release Mic [PTT] to return to Reception mode. • The TX-RX LED lights green or turns off, depending on the SQL control position. 7 Press [MIC (CAR)] or [CLR] to exit the Microphone gain adjustment mode. Refer to "COMMUNICATING AIDS", beginning on page 29, for information on additional useful operation functions. Note: When the TX power meter reading exceeds the value that you specified in the TX Power setting {page 58}, decrease the microphone gain or adjust your tone and level of voice. 21
