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.

Multi-function meter.
Multi-function meter
Displays the drain Displays the temperature
voltage of the final of the final amplifier
amplifier MOS-FETs. MOS-FETs.
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.
