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 sub-
display.

4 Press and hold Mic [PTT].

•

The TX-RX LED lights red.

•

Refer to “VOX” {page 30} 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 31} 
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 28, for information on additional useful operation 
functions.

FM is a common mode for communicating on VHF or 
UHF frequencies.  As for HF and the 6 m band, 
29 MHz and 51-54 MHz bands are commonly used 
for FM operation. You can also utilize 10 m/ 6 m band 
repeaters to reach your friends when they are outside 
or skipped over from your 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 suppresses background 
noise on the frequency, FM can be the best method 
for maintaining casual communications with your local 
friends.

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 “FM” appears.

•

If “FM” does not appear, select “AM”, then press 
[FM/AM (FM-N)].  The mode indicator changes 
to “FM”.

3 Press and hold Mic [PTT].

•

The TX-RX LED lights red.

•

Refer to “VOX” {page 30} for information on 
automatic TX/ RX switching.

4 Speak into the microphone in your normal 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 1 (Normal), 2 (Medium), and 3 (High) 
by using Menu No. 47.  1 (Normal) is usually 
appropriate; however, select 3 (High) if other 
stations report that your modulation is weak.

5 Release Mic [PTT] to return to Reception mode.

•

The TX-RX LED lights green or turns off, 
depending on the SQL control position.

Refer to “COMMUNICATING AIDS”, beginning on 
page 28, 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 1 (Normal), 2 
(Medium), or 3 (High) in Menu No. 47.
