BASIC OPERATION
The transceiver uses the same control [RF/SQL] to
adjust either the RF gain and the squelch.
By default, when the control is set to the 12 o’clock
position, rotating the control counterclockwise adjusts
the RF gain, and clockwise adjusts the squelch level
as shown below.

L The function of the [RF/SQL] control can be customized
in the Initial Set mode. (p. 20)
D RF gain
You can adjust the receive sensitivity.
If a strong interfering signal is received, rotate
[RF/SQL] counterclockwise to reduce the RF gain.
NOTE: We recommend setting the RF Gain control
to the 12 o’clock position since this sets RF gain to
the maximum.
D Squelch (SQL) level
The S-meter squelch mutes the audio output from the
speaker or headphones when the received signal is
weaker than the specied S-meter squelch level.
Rotate the [RF/SQL] clockwise from the 12 o’clock
position to increase the S-meter threshold level.
L The meter segments display the S-meter squelch level.
Meter display selection
You can display one of the transmit parameters (Po,
ALC, and SWR) for your convenience.
Push [SET] several times to select one of the meters.
Meter functions
(none): Displays the receiving signal strength level.
Po: Displays the relative RF output power.
ALC: Displays the ALC level. When the meter
movement shows the input signal level
exceeds the allowed level, the ALC limits
the RF power. In such cases, decrease the
microphone gain level.
SWR: Displays the SWR of the antenna at the
displayed frequency.
Adjusting the transmit output
power
Before transmitting, monitor your selected
operating frequency to make sure you do not cause
interference to other stations on the same frequency.
1. Hold down [SET] for 1 second.
• Enters the Quick Set mode.
2. Push[UP▲]/[▼DN] to select “RF Power.”
3. Rotate [MAIN DIAL] to set the output power to
between L (Low), 1 ~ 99, and H (High).
RF Power value
4. PUSH [SET] to exit the Quick Set mode.
The usable power
SSB/CW/RTTY: 2 (or less) ~ 100 W
AM: 2 (or less) ~ 35 W (Career power)
Adjusting the microphone gain
Properly adjust the microphone gain to prevent distort
your transmitted signal.
1. Set the operating band and mode to SSB or AM.
2. Hold down [SET] for 1 second.
• Enters the Quick Set mode.
3. Push[UP▲]/[▼DN] to select “MIC GAIN.”
4. Hold down [PTT] and adjust the microphone gain.
L Information
• Hold the microphone 5 to 10 cm (2 to 4 inches) from
your mouth, then hold down [PTT] on the microphone
and speak at your normal voice level.
• In the SSB mode, set the meter to the ALC meter,
and rotate [MAIN DIAL] to adjust the microphone gain
until the meter reading does not peak past the ALC
zone.

• In the AM mode, check the audio clarity with another
station.
5. Release [PTT].
6. Push [SET] to exit the Quick Set mode.
