10 [
CW-BPF
]
Function : Setting the bandwidth for the DSP
CW audio filter.
Available Values : 25/100/200/400 Hz
Default Setting : 200 Hz
This selection determines the bandwidth of the DSP
CW Peaking Filter. The most narrow setting is highly
useful for very-weak-signal VHF/UHF CW work, such
as EME (see Appendix, page 102). Use 200 Hz or 400
Hz for everyday operation.
11 [
DSP-NR
]
Function : Setting the degree of DSP Noise
Reduction.
Available Values : 0 ~ 15 (arbitrary scale)
Default Setting : 7
A higher setting provides more noise reduction, with
a slight loss of fidelity on the incoming signal.
12 [
TONE-FRQ
]
Function : Setting the CTCSS Tone Frequency.
Available Values : 39 standard CTCSS Tones
(see chart below)
Default Setting : 88.5 Hz
The available tones are shown in the chart below.
13 [
DCS-CODE
]
Function : Setting the DCS Code.
Available Values : 104 standard DCS Codes
(see chart below)
Default Setting : DCS Code #023
The available DCS codes are shown in the chart be-
low.

VHF-ARS
]
Function : Activate/deactivate the A utomatic
R epeater S hift when operating on
the 144 MHz band.
Available Values : O

FF
Default Setting : O
N
The ARS feature is operational when using the
MAIN
VFO
Tuning Dial,
MEM/VFO CH
knob, or the scan-
ning switches on the microphone; it does not function
when tuning via the
SUB-TUNE knob.
15 [

R epeater S hift when operating on
the 430 MHz band.

SUB-TUNE knob.
16 [
28M-RPT
]
Function : Set the magnitude of the Repeater
Shift to be utilized when operat-
ing on the 28 MHz band.
Available Values : 0.00 ~ 99.99 MHz
Default Setting : 0.10 MHz (100 kHz)
Any attempt to set a shift greater than 1.7 MHz will
result in an “
E
RROR
” message when you transmit, as
the resulting transmit frequency would be outside the
amateur band.
17 [
50M-RPT
]
Function : Set the magnitude of the Repeater
Shift to be utilized when operat-
ing on the 50 MHz band.
Available Values : 0.00 ~ 99.99 MHz
Default Setting : 1.00 MHz
Any attempt to set a shift greater than 4 MHz will re-
sult in an “
E
RROR
” message when you transmit, as the
resulting transmit frequency would be outside the
amateur band.
