Before starting, connect your key line(s) to the front and/or rear panel KEY jack(s). Be sure the [ BK-IN ] button is
turned off for now.
1. Press the [ MODE ] button to engage CW operation.
The "CW" and "USB" icons will appear in the dis-
play. The LED inside the [ MONI ] button glows or-
ange; and the CW monitor is activated.

If you select the "CW" mode again, you will engage
the "CW Reverse" mode, whereby the "opposite"
sideband injection is used, compared to the "normal"
sideband. The "CW" and "LSB" icons will appear
in the display if you select CW Reverse.
2. Rotate the Main Tuning Dial knob to select the de-
sired operating frequency.
3. Press the [ BK-IN ] button to engage automatic acti-
vation of the transmitter when you close the CW key.
The LED inside the [ BK-IN ] button glows orange.

 When you close your CW key, the transmitter
will automatically be activated, and the CW car-
rier will be transmitted. When you release the
key, transmission will cease, and after a brief
delay, receive will be restored. The delay time is
user-programmable per the discussion on page
83.
 As shipped from the factory, the FT
RX system for CW is configured for "Semi-
break-in" operation. However, using Menu item
"061 CW BK-IN", you may change this setup
for full break-in (QSK) operation, whereby the
switching is quick enough to hear incoming sig-
nals in the spaces between 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.

 You may adjust the CW sidetone audio level setting
of Menu item "035 MONITOR LEVEL".
To adjust the Monitor level:
1) Activate the MONI circuitry, if necessary.

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 recover after a short delay. No signals will be heard during 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, incoming
signals may be heard between the dots and dashes as you send them. This allows you to hear a station that sud-
denly starts transmitting on your frequency, while you are in the midst of a transmission.

(or press the p/q button) to adjust the monitor
level.
5) When you are satisfied with the setting, press
the [ SELECT ] button, then press the [ MENU ]
button to save the new setting and exit to normal
operation.
 If you set the [ BK-IN ] button to Off, you may prac-
tice sending CW with the sidetone only, without hav-
ing the signal go out over the air.
 If you reduce power via the Menu item "177 TX
MAX POWER", 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).
