BASIC COMMUNICATIONS

SSB TRANSMISSION

SSB is the most commonly-used mode on the HF Amateur bands. Compared with other voice modes, SSB requires only a narrow bandwidth for communications. SSB also allows long distance communications with minimum transmit power.

If necessary, refer to “OPERATING BASICS”, beginning on page 18, for details on how to receive.

1Select an operating frequency.

2Press [LSB/ USB/ AUTO] to select either lower or upper sideband mode.

•“LSB” or “USB” appears to show which sideband is selected.

3Press [MIC/ CAR] to activate the Microphone Gain Adjust.

• The current gain level appears.

4Press [SEND], or press and hold Mic [PTT].

•The MAIN band LED lights red.

•Refer to “VOX” {page 39} for information on automatic TX/RX switching.

5Speak into the microphone and adjust 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 40} for details.

6Press [SEND] or release Mic [PTT] to return to receive mode.

•The MAIN band LED lights green or turns off, depending on the MAIN SQL setting.

7Press [MIC/ CAR] to quit the Microphone Gain Adjust.

Refer to “COMMUNICATING AIDS”, beginning on page 37, for information on additional useful operation functions.

FM TRANSMISSION

FM is a common mode for communicating on VHF or UHF frequencies. Many amateur radio operators use their portable radios and mobile transceivers in FM mode. You can also utilize repeaters to reach your friends when they are outside your antenna coverage. Although FM requires a wider bandwidth when compared to SSB or AM mode, it has the finest audio quality among these modes. When combined with the full-quieting aspect of FM signals, which suppress background noise on the frequency, FM can be the best method for maintaining regular schedules with your local friends.

If necessary, refer to “OPERATING BASICS”, beginning on page 18, for details on how to receive.

1Select an operating frequency.

2Press [FM/ AM/ NAR] to select FM mode.

• “FM” appears.

3Press [SEND], or press and hold Mic [PTT].

•The MAIN band LED lights red.

•Refer to “VOX” {page 39} for information on automatic TX/RX switching.

4Speak into the microphone 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 can switch the Microphone Gain for FM between “LOW”, “MID”, and “HIGH” by using Menu No. 41. “LOW” is usually appropriate; however, select high if other stations report that your modulation is weak. The MULTI/ CH control has no effect in FM mode.

5Press [SEND] or release Mic [PTT] to return to receive mode.

•The MAIN band LED lights green or turns off, depending on the MAIN SQL setting.

Refer to “COMMUNICATING AIDS”, beginning on page 37, for additional information on useful operation functions.
