Adjusting the Carrier Level

The steps to adjust the carrier level in the CW, FSK, PSK and AM
modes are as follows.
1 Press [CAR] to display the Carrier Level
configuration screen.
.
2 Transmit in the CW, FSK, PSK or AM mode.
3 Press F4 [–]/ F5 [+] or turn the [MULTI/CH] control
to adjust the carrier level while referring to the ALC
meter.
Setting Value 0 to 50 (default) to 100 (1 step)
• CW/ FSK mode: Adjust the carrier level while ensuring that
the ALC meter reading does not exceed the ALC zone.
• AM/ PSK mode: Adjust the carrier level until the ALC meter
needle starts to deflect.
• SSB/ FM mode: The carrier level value is fixed. (Cannot be
adjusted)
4 Press [CAR] or [ESC] to end the process.
Note that the TX output will be disabled if the setting
●
value of carrier level is "0".

Operation in CW Mode

In the world of amateur radio, there is active communication in the
CW mode. This is because this mode of communication consumes
less power than SSB, and can be regarded as the simplest type of
digital communication that combines the use of "dots" and
"dashes".
• The built-in electronic keyer of this transceiver offers a wide
variety of functions to support the operation of the users. For
more details, please refer to
1 Select band and frequency.
Select a frequency band and configure the frequency.
2 Press [CW/ CW-R] to select CW mode.
3 Press [SEND] to transmit.
4 Operate the electronic keyer or paddle to transmit
a Morse code signal.
While transmission is in progress, a sidetone for monitoring the
Morse code of one's own station can be heard. The frequency
of the sidetone changes in tandem with the pitch frequency.
5 After the Morse code is transmitted, press [SEND]
to end the transmission.
This transceiver is restored to the receiving state.
The sidetone volume can be adjusted in Menu [1-02]

CW Break-in

Break-in is a convenient function that places this transceiver in the
TX mode simply by switching to the key-down state when in the
CW mode, and restores this transceiver to the RX mode upon
switching to the key-up state. Break-in is divided into 2 types, full
break-in and semi break-in.
Full Break-in
Switches this transceiver from the TX mode to the RX mode at
almost the same time as the key-up operation.
Semi Break-in
This transceiver does not return to the RX mode immediately after
the key-up operation, but remains in the TX mode and switches to
the RX mode only after the preconfigured delay time has elapsed.

Turning ON/OFF Break-in

Press [VOX].
Pressing [VOX] each time toggles break-in between the ON
and OFF states.
• When break-in is ON, the [VOX] LED lights up.

Adjusting the Break-in Mode and Break-in Delay Time

1 Press [VOX] to set break-in to ON.
2 Turn the [DELAY] control to adjust the delay time
after key-up.
FULL-BK/ 50 to 500 (default) to 1000 [ms] (50
Setting Value
step)
• Turn the [DELAY] control all the way to the left, and the full
break-in mode is activated when "FULL-BK" is displayed.
• Turning the control to the right lengthens the delay time while
turning the control to the left shortens it.
• "FULL-BK" or "DELAY:nn" ([nn: 1 to 20 (equivalent to 50ms
to 1000ms)]) is displayed at the top right corner of the filter
information area.
3 Operate the electronic keyer or paddle.
Transmission/reception is repeated automatically according to
the dot and dash Morse code.
Before using this transceiver in combination with a linear
●
amplifier, check whether the linear amplifier supports full
break-in. If its compatibility with full break-in is unknown
or if it is not compatible, operate using the semi break-in
mode.
Full break-in and semi break-in cannot be used at the
●
same time.
