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.
1 Select an operating frequency.
2 Press [LSB/ USB/ AUTO] to select either lower or
upper sideband mode.
• “LSB” or “USB” appears to show which
sideband is selected.
3 Press [MIC/ CAR] to activate the Microphone
Gain 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 on
automatic TX/RX switching.
5 Speak 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.
6 Press [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.
7 Press [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.
1 Select an operating frequency.
2 Press [FM/ AM/ NAR] to select FM mode.
• “FM” appears.
3 Press [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.
4 Speak 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.
5 Press [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.
Note: Microphone gain adjustment for SSB or AM has no effect in
FM mode. In FM mode, you must select “LOW”, “MID” or “HIGH” in
Menu No. 41.
