Function: Sets the AGC-SLOW DELAY voltage
decay characteristics for RTTY mode.
Available Values: 20 - 4000msec
Default Setting: 1500msec
Description: Sets the AGC voltage decay char-
acteristics in 20msec steps after the
input signal level becomes lower
than the AGC detection level and the
HOLD time has expired.

ter in RTTY mode.
Available Values: OFF / 100Hz - 1000Hz
Default Setting: 300Hz
Description: The cutoff frequency can be set at
50Hz increments between 100Hz
and 1000Hz.

Function: Sets the slope of the low-frequency
cutoff audio filter in RTTY mode.
Available Values: 6dB/oct / 18dB/oct
Default Setting: 18dB/oct
HCUT FREQ
Function: Sets the high-frequency cutoff audio
filter in RTTY mode.
Available Values: 700Hz - 4000Hz / OFF
Default Setting: 3000Hz
Description: The cutoff frequency can be set at
50Hz increments between 700Hz
and 4000Hz.
HCUT SLOPE
Function: Sets the slope of the high-frequency
cutoff audio filter in RTTY mode.
Available Values: 6dB/oct / 18dB/oct
Default Setting: 18dB/oct
USB OUT LEVEL

nal output from the USB jack.
Available Values: 0 - 100
Default Setting: 50
REAR OUT LEVEL
Function: Sets the level of the receive RTTY sig-
nal output from the RTTY/DATA jack.
Available Values: 0 - 100
Default Setting: 50
RPTT SELECT
Function: Sets the PTT control for the RTTY
transmit signal.
Available Values: OFF / RTS / DTR / DAKY
Default Setting: OFF
Description:
OFF: No PTT control.
RTS: Controls the RTTY transmit signal from
the USB virtual COM/RTS ports.
DTR: Controls the RTTY transmit signal from
the USB virtual COM/DTR ports.
DAKY: Controls the RTTY transmit signal from
the RTTY/DATA jack (pin 3) on the rear
panel.
NAR WIDTH
Function: Sets the IF BANDWIDTH of the digital
filter when the [NAR] key is pressed in
RTTY mode.
Available Values: 50 / 100 / 150 / 200 / 250 / 300/
350 /

2000 / 2400 / 3000 / 3200 /
3500 / 4000 (Hz)
Default Setting: 300Hz
MARK FREQUENCY
Function: Sets the mark frequency for RTTY
mode.
Available Values: 1275 / 2125 (Hz)
Default Setting: 2125Hz
SHIFT FREQUENCY
Function: Sets the shift width for RTTY mode.
Available Values: 170 / 200 / 425 / 850 (Hz)
Default Setting: 170Hz
POLARITY TX
Function: Sets the shift direction for transmitting
in RTTY mode.
Available Values: NOR / REV
Default Setting: NOR
Description:
NOR: The space frequency will be lower than the
mark frequency.
REV: The mark frequency will be lower than the
space frequency.
