050 CW LCUT FREQ
Function: Sets the low-frequency cutoff audio filter in
CW mode.
Available Values: OFF/100Hz - 1000Hz
(
50Hz/step
)
Default Setting: 250Hz
Description: This is the low-frequency cutoff audio lter
in CW mode.
The cutoff frequency can be set at 50 Hz
increments between 100 Hz and 1000 Hz.
051 CW LCUT SLOPE
Function: Sets the slope of the low-frequency cutoff au-
dio lter in CW mode.
Available Values: 6dB/oct / 18dB/oct
Default Setting: 18dB/oct
Description: Selects the slope of the low-frequency cut-
off audio lter in CW mode.
052 CW HCUT FREQ
Function: Sets the high-frequency cutoff audio lter in
CW mode.
Available Values: OFF/700Hz - 4000Hz
(
50Hz/step
)
Default Setting: 1200Hz
Description: This is the high-frequency cutoff audio l-
ter in CW mode.
The cutoff frequency can be set at 50 Hz
increments between 700 Hz and 4000 Hz.
053 CW HCUT SLOPE
Function: Sets the slope of the high-frequency cutoff au-
dio lter in CW mode.
Available Values: 6dB/oct / 18dB/oct
Default Setting: 18dB/oct
Description: Selects the slope of the high-frequency cut-
off audio lter in CW mode.
054 CW OUT LEVEL
Function: Sets the level of the CW signal output from
the
RTTY/DATA
jack.
Available Values: 0 - 100
Default Setting: 50
055 CW AUTO MODE
Function: Enables/disables CW keying while operating
on SSB.
Available Values: OFF/50M
(
50MHz
)
/ON
Default Setting: OFF
Description:
OFF: Disables CW keying while operating on
SSB.
50M: Enables CW keying while operating SSB on
50 MHz
(
but not HF
)
.
ON: Enables CW keying while operating SSB on
all TX bands.
056 CW BK-IN TYPE
Function: Sets the CW brake-in function.
Available Values: SEMI/FULL
Default Setting: SEMI
Description: Selects the CW brake-in function.
SEMI: A brief delay is provided after the CW
keying operation, before the transceiver
returns to receive mode.
The receiver recovery time may be changed
using MENU “
057 CW BK-IN DELAY
”.
FULL: The transceiver immediately returns to re-
ceive mode after every CW key-up
(
QSK
mode
)
.
057 CW BK-IN DELAY
Function: Sets the CW delay time.
Available Values: 30msec - 3000msec
(
10msec/step
)
Default Setting: 200msec
Description: In semi break-in mode, this setting deter-
mines the delay time before returning to re-
ceive mode after the CW keying operation.
The delay time can be changed in 10 msec
steps between 30 msec and 3000 msec.
058 CW WAVE SHAPE
Function: Selects the CW carrier wave-form shape
(
rise/
fall times
)
.
Available Values: 2ms/4ms
Default Setting: 4ms
(
msec
)
Description: Sets the rise and fall times of the keying en-
velope in CW mode

059 CW FREQ DISPLAY
Function: Sets the PITCH frequency offset.
Available Values: DIRECT FREQ/PITCH OFFSET
Default Setting: PITCH OFFSET
Description:
Sets the displayed frequency offset when
switching the transceiver mode between SSB
and CW.
DIRECT FREQ:
Displays the same frequency in CW mode as in
SSB mode without any offset added.
PITCH OFFSET:
Displays the frequency in CW mode with the
pitch offset added. When CW BFO is set to USB,
the displayed frequency will be increased and
when CW BFO is set to LSB, the displayed fre-
quency will be decreased with pitch offset added.
