D Meter Display Selection; D Multi-Function Meter - Icom IC-905 Basic Manual

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.
The selected meter's
icon is displayed.

D Multi-function meter

You can simultaneously display all the parameters.
L The TEMP meter is also displayed on the Multi-function
meter.
L You can select whether to display the Vd or DC IN meter.

Multi-func. Meter Voltage Display
Touch the currently displayed parameter for 1 second
to display the Multi-function meter.
ALC meter
ALC zone
When the DC IN meter is displayed:
When the DC IN meter reads above only the red under line,
the output power may decrease, or transceiver power may
be shut down.
TX inhibit zone
Displays the temperature
of the final amplifier
MOS-FETs.
3-10
S: Displays the receiving signal strength level.
Po: Displays the relative RF output power.
SWR: Displays the SWR of the antenna at the
displayed frequency.
L In the 10 GHz band, you cannot measure the
SWR.
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 case, 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.
L In the 10 GHz band, the drain voltage is
displayed only while transmitting, because the
power amplifier control method is different from
other bands.
Id: Displays the drain current of the final amplifier
MOS-FETs.
TEMP: Displays the temperature of the final amplifier
MOS-FETs.
DC IN: Displays the voltage of the external power
source.
