“straight key” or emulation thereof, as is provided by a computer-based keying device.

PERATION
1. Press the [ CW
] mode button to en-
gage CW operation.
A
DVICE
:
ˆ The operating mode is selected
using the [ MODE
] buttons to the
left of the Main Tuning Dial
knob, and the VFO (A or B) to
which the selection is applied is
selected by the [
A
] or [
B
] button
above the [ MODE
] buttons. Usu-
ally, the [ A
] button glow Red, sig-
nifying Main band (VFO-A) is
being adjusted. Similarly, pressing the [
B
] button
will cause its indicator to blink Orange for five sec-
onds, signifying Sub band (VFO-B) adjustment.
Therefore, press the [
A
] or [
B
] button to select the
desired VFO, then press the [ CW
] button to select
the CW mode.
ˆ If you press the [ CW
] button once more, after ini-
tially selecting CW, you will engage the “CW Re-
verse” mode (see page 86), whereby the “oppo-
site” sideband injection is used, compared to the
“normal” sideband. The LSB LED will blink for
three seconds if you select CW Reverse.
2. Rotate the Main Tuning Dial knob to select the desired
operating frequency.
3. Press the [
BK-IN
] button to engage automatic activa-
tion of the transmitter when you close the CW
key. The “
” icon will appear in the dis-
play.
A
DVICE
:
ˆ When you close your CW key, the transmitter will
automatically be activated, and the CW carrier will
be transmitted. When you release the key, trans-
mission will cease after a brief delay; the delay time
is user-programmable, per the discussion on page
87.
ˆ As shipped from the factory, the FT-2000D TX/
RX system for CW is configured for “Semi-break-
in” operation. However, using Menu item “
060 A1A
BK-IN ,” you may change this setup for full break-
in (QSK) operation, whereby the switching is quick
enough to hear incoming signals in the spaces be-
tween the dots and dashes of your transmission. This
may prove very useful during contest and traffic-
handling operations.
4. Operation using your CW key may now proceed.
A
DVICE
:
ˆ You can monitor your sending by pressing the [ MONI
]
button, and adjusting the [ MONI
] knob for a comfort-
able listening level on the CW sidetone.
ˆ If you set the [ VOX
] and [
BK-IN
] buttons to Off, you
may practice your sending without having the signal
go out over the air (sidetone only).
ˆ If you reduce power using the [ RF PWR
] knob, the
ALC meter reading will increase; this is normal and
does not indicate any problem whatsoever (because
increased ALC voltage is being used to lower the
power).
T
ERMINOLOGY
:
Semi-break-in
This is a pseudo- “VOX” mode used on CW, whereby
the closure of the CW key will engage the transmitter,
and release of the key will allow the receiver to re-
cover after a short delay. No signals will be heard be-
tween the spaces between dots and dashes (unless the
sending speed is extremely slow).
Full break-in
Full break-in (Also known as “Full QSK”) involves
very fast switching between transmit and receive, such
that incoming signals may be heard between the dots
and dashes as you send them. This allows you to hear a
station that suddenly starts transmitting on your fre-
quency, while you are in the midst of a transmission.
