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 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 TRANSMISSION

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.
