AGC SLOW DELAY
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.

Function: Sets the high-frequency cutoff audio
lter 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
cuto󰀨 audio lter in RTTY mode.

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
lter when the [NAR] key is pressed in
RTTY mode.
Available Values: 50 / 100 / 150 / 200 / 250 / 300/

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.
