ANUAL
CLAR (CLAR DIAL/SEL)
Function
: Setting of CLAR switch
Available Values
: DIAL / SEL
Default
: DIAL
Defines which Control knob is used for setting the
clarifier-offset frequency.
CLK SFT (CLOCK SHIFT)
Function
: Shifting of CPU clock frequency
Available Values
: ON / OFF
Default
: OFF
This function is only used to move a spurious re-
sponse “birdie,” should it fall on a desired frequency.
CONT (DISP CONTRAST)
Function
: Display contrast adjustment
Available Values
: 1~24
Default
: 24
The display contrast level is set 1-13
CW AUTO (CW AUTO MODE)
Function
: Enables the
KEY
jack, to permit CW op-
eration while in SSB modes.
Available Values
: OFF / ON
Default
: OFF
OFF: The
KEY
jack is enabled in CW mode only.
ON: The
KEY
jack is enabled on all modes (SSB
mode: A1A). Thus, on SSB, you can ask a sta-
tion for a CW QSO without having to change
your
FT-450
’s Mode selection, if Menu “
CW
AUTO
” is set to “ON.”
CW BFO
Function
: Sets the CW carrier oscillator injection
side in CW mode
Available Values
: USB / LSB / AUTO
Default
: USB
USB:
Injects the CW carrier oscillator on the USB
side
LSB:
Injects the CW carrier oscillator on the LSB
side
AUTO: Injects the CW carrier oscillator on the LSB
side while operating on the 7 MHz band and
below, USB side while operating on the 10
MHz band and up.
CW DLY (CW DELAY)
Function
: Sets the receiver recovery time during
pseudo-VOX CW semi-break-in opera-
tion.
Available Values
: FULL / 30~3000ms
Default
: 250
The recovery time may be adjusted in steps of 10
msec. A longer delay may be preferable if you pause
frequently while sending.
CW KEY (CW KEY REV)
Function
: Sets the keyer paddle's wiring configura-
tion.
Available Values
: NOR / REV
Default
: NOR
The polarity can be reversed in the menu without
changing the connection of the keyer when there is a
left-handed operator or, two or more people.
NOR(NORMAL): Keyer paddle polarity is normal.
The plug “Tip” connection pro-
duces dots, and the plug "ring" con-
nection produces dashes.
REV(REVERSE): Keyer paddle polarity is inverted.
The plug “Tip” connection pro-
duces dashes, and the “Ring” con-
nection produces dots.
CW QSK
Function
: Selects the time delay between when the
key is closed and the carrier is transmit-
ted during QSK operation when using the
internal keyer.
Available Values
: 15 / 20 / 25 / 30 (ms)
Default
: 15 (ms)
Note:
If you select “25 ms” or “30 ms,” please do not at-
tempt to set Menu “
CW SPEED
” to a speed faster than
50 wpm (250 cpm), as the delay will make it impos-
sible to transmit.
CWPADDL (CW PADDLE)
Function
: When enabled, the Optional microphone’s
(MH-31
A8J
) [
UP
]/[
DWN
] keys may be used
for CW keying.
Available Values
: KEY / MIC
Default
: KEY
KEY: The key connected to
KEY
Jack is selected.
MIC: When this Menu Item is set to “
MIC
,” the Op-
tional (MH-31A8J) microphone’s [
UP
]/[
DWN
]
keys may be used for CW keying. (while the
built-in electronic keyer is engaged).
CWPITCH
Function
: Sets the pitch of the CW sidetone, (BFO
offset) and the CW filter center frequen-
cies.
Available Values
: 400 / 500 / 600 / 700 / 800 (Hz)
Default
: 700
The CW pitch may be adjusted in steps of 100 Hz.
