RADIO SETTING
- MODE RTTY -
AGC FAST DELAY
Function: Sets the AGC-FAST DELAY voltage
decay characteristics for RTTY mode.
Available Values: 20 - 4000msec
Default Setting: 160msec
Description: Sets the AGC voltage decay char-
acteristics in 20 msec steps after
the input signal level becomes lower
than the AGC detection level and the
HOLD time has expired.
AGC MID DELAY
Function: Sets the AGC-MID DELAY voltage de-
cay characteristics for RTTY mode.
Available Values: 20 - 4000msec
Default Setting: 500msec
Description: Sets the AGC voltage decay char-
acteristics in 20 msec steps after
the input signal level becomes lower
than the AGC detection level and the
HOLD time has expired.
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 20 msec steps after
the input signal level becomes lower
than the AGC detection level and the
HOLD time has expired.
POLARITY RX
Function: Sets the shift direction for receiving 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.
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.

LCUT FREQ
Function: Sets the low-frequency cutoff audio fil-
ter in RTTY mode.
Available Values: OFF / 100Hz - 1000Hz
Default Setting: 300Hz
Description: The cutoff frequency can be set at
50 Hz increments between 100 Hz
and 1000 Hz.
LCUT SLOPE
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
50 Hz increments between 700 Hz
and 4000 Hz.
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
RTTY OUT SELECT
Function: RTTY signal output band setting from
RTTY/DATA jack.
Available Values: MAIN / SUB
Default Setting: MAIN
Description: Select the band to output the RTTY
signal.
RTTY 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: DAKY / RTS / DTR
Default Setting: DAKY
Description:
DAKY: Controls the RTTY transmit signal from
the RTTY/DATA jack (pin 3) on the rear
panel.
DTR: Controls the RTTY transmit signal from
the USB virtual COM/DTR ports.
RTS: Controls the RTTY transmit signal from
the USB virtual COM/RTS ports.
