When CW BFO is set to USB,the displayed frequency will be increased andwhen CW BFO is set to LSB, the displayed fre-quency will be decreased with pitch offset added.060 PC KEYINGFunction: Sets the RTTY/DATA jack for keying.Available Values: OFF/DAKY/RTS/DTRDefault Setting: OFFDescription:OFF:Disables keying from DATA PTT (pin 3) of theRTTY/DATA jack.DAKY:Controls the transmit from the RTTY/DATA jack(pin 3) on the rear panel.RTS:Controls the transmit from the USB virtual COM/RTS ports.DTR:Controls the transmit from the USB virtual COM/DTR ports.061 QSK DELAY TIMEFunction: Sets the time delay before transmitting thekeying signal.Available Values: 15/20/25/30msecDefault Setting: 15msecDescription: The delay time in QSK mode before trans-mitting the CW signal may be set in 5 msec steps.062 DATA MODEFunction: Selects the operating scheme in DATA mode.Available Values: PSK/OTHERSDefault Setting: PSKDescription: Selects the operating scheme (PSK orOTHERS) in DATA mode.063 PSK TONEFunction: Set the PSK tone.Available Values: 1000/1500/2000HzDefault Setting: 1000HzDescription: Selects the PSK tone frequency.064 OTHER DISP (SSB)Function: Sets the displayed frequency offset in DATAmode.Available Values: −3000 - 0 - 3000Hz (10Hz/step)Default: 0HzDescription: Sets the displayed frequency offset inDATA mode. The frequency can be set in steps of 10Hz.065 OTHER SHIFT (SSB)Function: Sets the carrier point in DATA mode.Available Values: −3000 - 0 - 3000Hz (10Hz/step)Default: 0HzDescription: Sets the carrier point in DATA mode. Thefrequency can be set in steps of 10 Hz.066 DATA LCUT FREQFunction: Sets the low-frequency cutoff audio filter inDATA mode.Available Values: OFF/100Hz - 1000Hz (50Hz/step)Default Setting: 300HzDescription: This is the low-frequency cutoff audio filterin DATA mode.The cutoff frequency can be set at 50 Hz incrementsbetween 100 Hz and 1000 Hz.067 DATA LCUT SLOPEFunction: Sets the slope of the low-frequency cutoff au-dio filter in DATA mode.Available Values: 6dB/oct / 18dB/octDefault Setting: 18dB/octDescription: Selects the slope setting of the low-fre-quency cutoff audio filter in DATA mode.068 DATA HCUT FREQFunction: Sets the high-frequency cutoff audio filter inDATA mode.Available Values: OFF/700Hz - 4000Hz (50Hz/step)Default Setting: 3000HzDescription: This is the high-frequency cutoff audio fil-ter in DATA mode.The cutoff frequency can be set at 50 Hz incrementsbetween 700 Hz and 4000 Hz.069 DATA HCUT SLOPEFunction: Sets the slope of the high-frequency cutoff au-dio filter in DATA mode.Available Values: 6dB/oct / 18dB/octDefault Setting: 18dB/octDescription: Selects the slope setting of the high-fre-quency cutoff audio filter in DATA mode.070 DATA IN SELECTFunction: Selects the input jack for DATA mode.Available Values: MIC/REARDefault Setting: REARDescription: Selects the input jack to be used in DATAmode.MIC:Inputs signals from the MIC jack on the frontpanel.REAR:Inputs signals from the USB jack or RTTY/DATA jack on the rear panel.M enu M oDe
