FUNCTION
SWITCH
This control varies the gain of
the RF stage when the transceiver
is
in the receive mode. Rotate the control fully
clockwise
for
maximum gain. When tuning in the SSB
or CW
mode, the
S-meter
needle
rises
as
the control
Is
rotated counterclockwise and
only
those
signals stronger than the
level
indicated by the
needle
are
heard.
This
control
sets
the
squelch threshold
level. To turn
OFF
the
squelch function, rotate
this control completely counterclockwise.
To set
the threshold
level higher, rotate the control clockwise.
Adjust this control
clockwise until the green
RECEIVE
indicator
just goes out
while
no
signal
is
being received.
This control
varies the receive
audio tone. Adjust
the
control
to
provide the clearest,
most pleasing audio.
Adjust this
control for
a
suitable modulation
level while speaking
into
the microphone in a
normal voice. Rotate the control clock-
wise to
increase the gain.
This control varies the
RF
output power from 10 watts
to
maximum.
