Rotate
Adjusting the microphone gain
Adjust the microphone gain as described below.
1.
Set the operating band and mode to SSB, AM, FM
or DV. (p. 3-3)
Meter display
D
Meter display selection
You can display one of the 6 different transmit
parameters (Po, SWR, ALC, COMP, VD and ID) for
your convenience.
Touch the parameter to display one of the meters.
D
Multi-function meter
You can display all the parameters simultaneously.
L
The TEMP meter is also displayed on the Multi-function
meter.
Hold down the parameter for 1 second to display the
Multi-function meter.
ALC meter
ALC zone
Multi-function meter
2. Push
MULTI
to display the Multi-function menu.
3.
Touch “MIC GAIN,” and rotate
MULTI
to adjust the
microphone.
L
Setting “50%” can be used for most voice operations,
but do following to make sure the microphone gain is
properly set.
•
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, touch the TX meter to select
the ALC meter, and rotate
MULTI
to adjust the
microphone gain until the meter reading swings
between 30 to 50% of the ALC scale.
• In the AM, FM or DV mode, check the audio clarity with
another station, or use the Monitor function (p. 4-7).
S:
Displays the receiving signal strength level.
Po:
Displays the relative RF output power.
SWR:
Displays the SWR of the antenna at the
frequency.
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.
COMP:
Displays the compression level when the
speech compressor is used.
VD:
Displays the drain voltage of the final amplifier
MOS-FETs.
ID:
Displays the drain current of the final amplifier
MOS-FETs.
TEMP:
Displays the temperature of the final amplifier
MOS-FETs.
When the VD meter
reads on the red under
line or below, the output
power may decrease or
transceiver power may be
shut down.
Displays the temperature of
the final amplifier MOS-FETs.
