METER Switch
This control switch determines the function of the
Main Meter during transmission.
COMP : Indicates the RF speech compressor
level (SSB modes only).
PO : Indicates the power output level.
SWR
: Indicates the Standing Wave Ratio (For-
ward: Reflected).
IDD
: Indicates the final amplifier drain cur-
rent.
MIC LVL
: Indicates the relative microphone level.
MONI (Monitor) Switch
This button enables the transmit (RF) monitor in all
modes (except CW, in which the monitor function
is always on, to produce the sidetone). While acti-
vated, the LED in this button glows red. Adjustment
of the Monitor level is accomplished using the
MONI knob, located just to the right of the
MONI switch.
Advice
When using headphones, the Monitor is highly use-
ful for making adjustments to the Parametric Equal-
izer or other voice quality adjustments, because the
voice quality heard in the headphones is such a “natu-
ral” reproduction of the transmitted audio quality.
MONI PITCH Knobs
MONI Knob
The inner MONI knob adjusts the audio level of the
transmit RF monitor during transmission (relative to the
AF GAIN control), when activated by the MONI but-
ton (above).
PITCH Knob
The outer PITCH knob selects your preferred CW
tone pitch (from 300 ~ 1000 Hz, in 50 Hz increments).
The Tx sidetone, receiver IF passband, and display off-
set from the BFO (carrier) frequency are all affected
simultaneously. The Pitch control setting also affects
the operation of the CW Tuning Indicator, as the center
frequency of the CW Tuning Indicator will follow the
setting of this control.
AGC ATT Knobs
AGC Knobs
This switch selects the AGC characteristics for the Main
(VFO-A) band receiver.
ATT Knobs
This switch selects the degree of attenuation, if any, to
be applied to the Main (VFO-A) receiver input.
Advice
The Attenuator may be used in conjunction with the IPO
switch (#
above) to provide two stages of signal re-
duction when an extremely strong signal is being re-
ceived.
