AUTO ZERO-IN (CW AUTO TUNE)
If you wish to have a QSO in CW mode with another CW
station, use this function so that the transmit frequency
of your station will automatically be tuned to the receive
frequency of the other station.

1 Rotate the Tuning control and make rough
adjustments so that you can hear the received CW.
2 Press [CW T] (M) or [CW T] (S) to enable the Auto
Zero-in (CW Auto Tune).
• "CW TUNE" blinks on the main screen.
• The transmit frequency is automatically tuned to the
receive frequency, and the receive signal pitch is tuned to
the sidetone and receive pitch frequency.
• The Auto Zero-in (CW Auto Tune) disappears from the
main screen when the transmit frequency has zeroed in
on the receive frequency. If the transmit frequency cannot
automatically be zeroed in (CW Auto Tune), the frequency
reverts to the previous frequency.
Note:
◆ If you use the Auto Zero-in (CW Auto Tune), you can tune into a
frequency within ±50 Hz of the receive frequency from the station
you wish to call.
◆ The transceiver may not be able to zero in automatically (CW Auto
Tune) if the CW keying speed of the station you are communication
to is too slow or the signal strength of the station is weak or if there
is interference.
◆ If RIT is active, the Auto Zero-in (CW Auto Tune) works on the
frequency shifted with RIT.
◆ The range where the Auto Zero-in (CW Auto Tune) functions varies
depending on the receive conditions.
◆ While the Bandscope or Waterfall screen is open, Auto Zero-in
(CW Auto Tune) can function by touching the screen longer than
the time configured in Menu 0-12, "Long Press Duration of Panel
Keys".
CARRIER FREQUENCY OFFSET WHEN
CHANGING FROM SSB MODE TO CW MODE
If you receive a CW signal from a station and you wish to
have a QSO with the station while you are operating the
transceiver in SSB mode, you have to change the mode
to CW. In that case, you need to rotate the Tuning control
slightly for a carrier frequency offset. Using this function
will automatically correct the frequency.

4 Press [-] (F4) or [+] (F5) to select “On” or “Off”.
The default is “Off” (not correcting the frequency). Selecting
“On” allows the transceiver to correct the frequency.
