PERATION
1. Press the [
CW ] mode button
to engage CW operation.
The “
” and “ ”
icons will appear in the dis-
play. The “
” icon
will also appear in the dis-
play; and the CW monitor is
activated.
A
DVICE
:
The operating mode
is selected using the
[
MODE
] button.
The VFO, to which
the selection is ap-
plied, is selected by the [
A
] or [
B
] button (located
to the upper left of the Main Tuning Dial knob).
Usually, the [
A ] button glows red, signifying VFO-
A is being adjusted. Alternately, pressing the [ B
]
button will cause its indicator to glows orange, sig-
nifying 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.
After initially selecting CW, if you press the [
CW ]
button once more, you will engage the “CW Re-
verse” mode (see page 92). Normally, the upper
sideband (USB) is used in conjunction with CW.
In reverse CW the lower sideband (LSB) is used.
2. Rotate the Main Tuning Dial knob to select the desired
operating frequency.
3. Press the [
BK-IN ] button
briefly, to engage automatic
activation of the transmitter
when you close the CW key.
The “
” icon will appear
in the display.
A
DVICE
:
When you close your CW
key, the transmitter will automatically be activated,
and the CW carrier will be transmitted. When you
release the key, transmission will cease after a brief
delay; the delay time is user-programmable, per the
discussion on page 93.
As shipped from the factory, the FT
DX
5000 TX/
RX system for CW is configured for “Semi-break-
in” operation. However, using Menu item “
063 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 CW sidetone sounds from a speaker
in accordance with your keying. Ad-
just the [
MONI
] knob for a comfort-
able listening level of the CW
sidetone.
