[
MIN-FREQ
]
Function
:
Setting of the minimum synthe-
sizer step size for the
MAIN VFO
Tuning Dial.
Available Values

[
SSB-CH
]
Function
:
Setting of the synthesizer steps in
the SSB mode when using the
MEM/VFO CH
knob.
Available Values
: 1.0/2.5/5.0 kHz
Default Setting
:
2.5 kHz
The
MEM/VFO CH
knob is extremely useful for mak-
ing quick frequency excursions. The 5 kHz setting may
be useful for situations when you ask a station to move
“5 kHz U
P
” for a contact, while the 1 kHz setting is
useful for precise tuning of SSB signals. This setting
may be performed
individually
on HF, 50 MHz, 144
MHz, and 430 MHz.
4
[
AM-CH
]
Function
:
Setting of the synthesizer steps in
the AM mode when using the
MEM/VFO CH
knob.
Available Values
: 2.5/5.0/9.0/10.0/12.5/25.0 kHz
Default Setting
:
5.0 kHz
The 9.0 kHz setting may be useful for channel-by-chan-
nel tuning of AM broadcast stations. This setting may
be performed
individually
on HF, 50 MHz, 144 MHz,
and 430 MHz.
5
[
FM-CH
]
Function
:
Setting of the synthesizer steps in
the FM mode when using the
MEM/VFO CH
knob.
Available Values
: 5/6.25/10/12.5/15/20/25 kHz
Default Setting
:
HF: 5 kHz
VHF/UHF: Depends on trans-
ceiver version (U.S.A., European, etc.)
This setting may be performed
individually
on HF, 50
MHz, 144 MHz, and 430 MHz.
6
[
CW-PITCH
]
Function
:
Setting of the pitch of the CW
sidetone, CW Spot, BFO offset,
and IF/DSP CW filter center fre-
quencies.
Available Values
: 400 ~ 1100 Hz
Default Setting
:
700 Hz
The CW sidetone frequency corresponds to the tone
of your signal as heard by another station. Align the
other station’s tone pitch to be the same as your CW
sidetone pitch, using the “S
POT
” feature, to “zero-beat”
to the other station. The CW Pitch alignment may be
performed in 50 Hz increments.
7
[
WEIGHT
]
Function
:
Setting of the radio between CW
Dashes and Dots for the internal
electronic keyer.
Available Values
: (Dot:Dash Ratio) 3.0:1 ~ 4.4:1
Default Setting
:
3.0:1
8
[
SIDETONE
]
Function
:
Setting the volume of the CW
Sidetone.
Available Values
: 0 ~ 63 (arbitrary scale)
Default Setting
:
32
This CW Sidetone Level adjustment is fixed via this
Menu item, and does not depend on the setting of the
AF
(G
AIN
) control.
9
[
CW-DELAY
]
Function
:
Setting the receiver recovery time
during pseudo-“VOX” CW semi-
break-in operation.
Available Values

Default Setting
:
100 ms.
The recovery time may be adjusted in steps of 10 ms.
A longer delay may be preferable if you pause fre-
