075. AGC-SLOPE
Function : Selects the gain curve of the AGC ampli-
fier.
Available Values : NORMAL/SLOPE
Default Setting : NORMAL
NORMAL: The AGC output level will follow a linear
response to the antenna input level, while
AGC is activated.
SLOPE: The AGC output level will increase at 1/10
the rate of the antenna input level, while
AGC is activated.
076. HEADPHONE MIX
Function : Selects one of three audio mixing modes
when using headphones during Dual Receive opera-
tion.
Available Values : SEPARATE/COMBINE-1/COM-
BINE-2
Default Setting : COMBINE-2
SEPARATE: Audio from the main (VFO-A) receiver
is heard only in the left ear, and sub
(VFO-B) receiver audio solely in the
right ear.
COMBINE-1: Audio from both main (VFO-A) and sub
(VFO-B) receivers can be heard in both
ears, but sub (VFO-B) audio is attenu-
ated in the left ear and main (VFO-A)
audio is attenuated in the right ear.
COMBINE-2: Audio from both main (VFO-A) and sub
(VFO-B) receivers is combined and
heard equally in both ears.
077. SPEAKER OUT
Function : Selects audio mixing modes for the “sub”
(secondary) speaker during Dual Receive operation.
Available Values : SEPARATE/COMBINE
Default Setting : COMBINE
SEPARATE: Audio from the main (VFO-A) receiver is
fed to the main speaker, and sub (VFO-
B) receiver audio is fed to the “sub”
speaker.
COMBINE: Audio from both main (VFO-A) and sub
(VFO-B) receivers is combined and split
equally between the main and sub
speakers.

078. MAIN-CONTOUR-LEVEL
Function : Adjusts the parametric equalizer gain of
the main band (VFO-A) receiver Contour filter.
Available Values : –40 ~ +20 dB
Default Setting : –15 dB
079. MAIN-CONTOUR-WIDTH
Function : Adjusts the Q-factor of the main band (VFO-
A) receiver Contour filter.
Available Values : 1 - 11
Default Setting : 10
080.SUB-CONTOUR-LEVEL
Function : Adjusts the parametric equalizer gain of
the sub band (VFO-B) receiver Contour filter.
Available Values : –40 ~ +20 dB
Default Setting : –15 dB
081. SUB-CONTOUR-WIDTH
Function : Adjusts the Q-factor of the sub band (VFO-
B) receiver Contour filter.
Available Values : 1 ~ 11
Default Setting : 10
082. IF-NOTCH-WIDTH
Function : Selects the bandwidth of the DSP NOTCH
filter
Available Values : NARROW/WIDE
Default Setting : WIDE
083. MAIN-CW-SHAPE
Function : Selects the passband characteristics of the
main band (VFO-A) DSP filter for the CW mode.
Available Values : SOFT/SHARP
Default Setting : SHARP
SOFT: Primary importance attached to amplitude
of the filter factor.
SHARP: Primary importance attached to phase of the
filter factor.
084. MAIN-CW-SLOPE
Function : Selects the shape factor of the main band
(VFO-A) DSP filter for the CW mode.
Available Values : GENTLE/MEDIUM/STEEP
Default Setting : MEDIUM
