Activates in all modes (except SSB with [COMP] OFF). !3 VOX GAIN CONTROL [VOX GAIN] (p. 8-2) Rotate to adjust the transmit/receive switching threshold level for VOX operation. !4 ANTI VOX CONTROL [ANTI VOX] (p. 8-2) Adjusts the VOX deactivate level to prevent un- wanted VOX activation from the speaker or other sounds. !5 D ISPLAY CONTRAST CONTROL [CONTRAST] Adjusts the display contrast. !6 D ISPLAY BRIGHTNESS CONTROL [BRIGHT] Adjusts the display brightness. !7 MONITOR KEY [MONI] (p. 8-5) Push to monitor your transmitted signal. • The CW sidetone functions regardless of the [MONI] key setting in the CW mode. • The [MONI] indicator above this key lights white while the function is activated. !8 BREAK-IN DELAY CONTROL [DELAY] (p. 8-4) Rotate to adjust the transmit-to-receive switching delay time in the CW semi-break-in mode. !9 E LECTRONIC CW KEYER SPEED CONTROL [KEY SPEED] (p. 5-7) Rotate to adjust the internal electronic CW keyer's speed to between 6 wpm (minimum) and 48 wpm (maximum). • The keyer's speed is displayed. @0 VOX/BREAK-IN KEY [VOX/BK-IN] ➥ Push to turn the VOX function ON or OFF in the SSB, AM, or FM mode. (p. 8-2) ➥ Push to turn the break-in function ON (Semi breakin, Full break-in) or OFF in the CW mode. (p. 8-4) ➥ Hold down for 1 second to enter the VOX set screen. (p. 8-3) ✔ What is the VOX function? The VOX function (voice operated transmission) starts transmission without pushing the transmit key or PTT switch when you speak into the microphone, then automatically returns to receive when you stop speaking. ✔ What is the break-in function? The break-in function toggles between transmit and receive with CW keying. Full break-in (QSK) can monitor the receive signal during keying. @1 RF POWER CONTROL [RF PWR] (p. 4-13) Rotate to continuously vary the RF output power from less than 5 watts (minimum) to 200* watts (maximum). *AM mode: less than 5 W to 50 W • The output power setting is displayed. @2 MIC GAIN CONTROL [MIC] Rotate to adjust microphone gain. • The transmit audio tone in the SSB, AM, or FM mode can be independently adjusted in the Level set screen. (p. 4-13) ✔ How to set the microphone gain. Adjust the [MIC] control so that the ALC meter swings within the ALC range during normal voice level transmission in the SSB or AM mode. (The ALC meter must be selected.) 1-3

PANEL DESCRIPTION

MICROPHONE CONNECTOR [MIC]

Connect an optional microphone.

• See page 3-4 for appropriate microphones.

• See page 20-3 for microphone connector information.

SD CARD SLOT [SD CARD]

(pp. 3-5, 10-2)

Insert the supplied SD card for both reading and stor-

ing a wide variety of the transceiver’s information and

data.

• The indicator beside the slot lights, or blinks when read

ing from or writing to the card.

• Push the card once to remove it.

USB INDICATOR [USB]

(p. 10-4)

Lights while accessing a USB ﬂash drive inserted to

the [USB A] port.

MONITOR GAIN CONTROL [MONI GAIN]

(p. 8-5)

Rotate to adjust the transmit IF signal monitor level.

COMPRESSION LEVEL CONTROL [COMP]

(p. 8-6)

Rotate to adjust the speech compression level in

SSB.

DRIVE GAIN CONTROL [DRIVE]

(p. 4-14)

Rotate to adjust the transmitter level at the driver

stage. Activates in all modes

(except SSB with [COMP]

OFF)

VOX GAIN CONTROL [VOX GAIN]

(p. 8-2)

Rotate to adjust the transmit/receive switching

threshold level for VOX operation.

ANTI VOX CONTROL [ANTI VOX]

(p. 8-2)

Adjusts the VOX deactivate level to prevent un

wanted VOX activation from the speaker or other

sounds.

DISPLAY CONTRAST CONTROL [CONTRAST]

Adjusts the display contrast.

DISPLAY BRIGHTNESS CONTROL [BRIGHT]

Adjusts the display brightness.

MONITOR KEY [MONI]

(p. 8-5)

Push to monitor your transmitted signal.

• The CW sidetone functions regardless of the [MONI] key

setting in the CW mode.

• The [MONI] indicator above this key lights white while

the function is activated.

BREAK-IN DELAY CONTROL [DELAY]

(p. 8-4)

Rotate to adjust the transmit-to-receive switching

delay time in the CW semi-break-in mode.

ELECTRONIC CW KEYER SPEED CONTROL

[KEY SPEED]

(p. 5-7)

Rotate to adjust the internal electronic CW keyer’s

speed to between 6 wpm (minimum) and 48 wpm

(maximum).

• The keyer’s speed is displayed.

VOX/BREAK-IN KEY [VOX/BK-IN]

➥

Push to turn the VOX function ON or OFF in the

SSB, AM, or FM mode.

(p. 8-2)

➥

Push to turn the break-in function ON

(Semi break-

in, Full break-in)

or OFF in the CW mode.

(p. 8-4)

➥

Hold down for 1 second to enter the VOX set

screen

. (p. 8-3)

✔

What is the VOX function?

The VOX function (voice operated transmission) starts

transmission without pushing the transmit key or PTT

switch when you speak into the microphone, then auto-

matically returns to receive when you stop speaking.

✔

What is the break-in function?

The break-in function toggles between transmit and

receive with CW keying. Full break-in (QSK) can moni

tor the receive signal during keying.

RF POWER CONTROL [RF PWR]

(p. 4-13)

Rotate to continuously vary the RF output power

from less than 5 watts (minimum) to 200* watts

(maximum).

*AM mode: less than 5 W to 50 W

• The output power setting is displayed.

MIC GAIN CONTROL [MIC]

Rotate to adjust microphone gain.

• The transmit audio tone in the SSB, AM, or FM mode

can be independently adjusted in the Level set screen.

(p. 4-13)

✔

How to set the microphone gain.

Adjust the [MIC] control so that the ALC meter swings

within the ALC range during normal voice level trans-

mission in the SSB or AM mode. (The ALC meter must

be selected.)
