RPTT SELECT
Function: Sets the PTT control for the CW trans-
mit signal.
Available Values: OFF / RTS / DTR / DAKY
Default Setting: OFF
Description:
OFF: No PTT control.
RTS: Controls the CW transmit signal from the
USB virtual COM/RTS ports.
DTR: Controls the CW transmit signal from the
USB virtual COM/DTR ports.
DAKY: Controls the CW transmit signal from the
RTTY/DATA jack (pin 3) on the rear panel.
NAR WIDTH
Function: Sets the IF BANDWIDTH of the digital
lter when the [NAR] key is pressed in
CW mode.
Available Values: 50 / 100 / 150 / 200 / 250 / 300/
350 / 400 / 450 / 500 / 600 /
800 / 1200 / 1400 / 1700 /
2000 / 2400 / 3000 / 3200 /
3500 / 4000 (Hz)
Default Setting: 250Hz
PC KEYING
Function: Sets the RTTY/DATA jack for PC keying.
Available Values: OFF / RTS / DTR / DAKY
Default Setting: OFF
Description:
OFF: Disables PC keying from DATA PTT (pin 3)
of the RTTY/DATA jack.
RTS: Controls the transmit from the USB virtual
COM/RTS ports.
DTR: Controls the transmit from the USB virtual
COM/DTR ports.
DAKY: Controls the transmit from the RTTY/
DATA jack (pin 3) on the rear panel.
CW BK-IN TYPE
Function: Sets the CW brake-in function.
Available Values: SEMI / FULL
Default Setting: SEMI
Description:
SEMI: A brief delay is provided after the CW key-
ing operation, before the transceiver re-
turns to receive mode.
The receiver recovery time may be
changed using “CW BK-IN DELAY”.
FULL: The transceiver immediately returns to re-
ceive mode after every CW key-up (QSK
mode).
CW WAVE SHAPE
Function: Selects the CW carrier wave-form
shape (rise/fall times).
Available Values: 4msec / 6msec / 8msec
Default Setting: 6msec
Description: Sets the rise and fall times of the
keying envelope in CW mode (trans-
mit waveform).
CW FREQ DISPLAY
Function: Sets the PITCH frequency o󰀨set.
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 with-
out any o󰀨set 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
frequency will be decreased
with pitch o󰀨set added.
QSK DELAY TIME
Function: Sets the time delay before transmitting
the keying signal.
Available Values: 15 / 20 / 25 / 30 msec
Default Setting: 15 msec
Description: The QSK mode delay time before
transmitting the CW signal may be
set in 5msec steps.
Notes: • When the keying speed of the CW is
“45 wpm” or more, delay time will be “15
msc” regardless of the delay time setting.
• This setting is valid in all communication
modes and the set TX delay time works
effectively for the TX GND pin of the
LINEAR jack on the rear panel.
CW INDICATOR
Function: Bar display settings shown below the
lter function display in CW mode.
Available Values: OFF / ON
Default Setting: ON
Description: In CW mode, the bar shown below
the lter function display may be set
to ON or OFF.
