5 BASIC COMMUNICATIONS
AUTO ZERO-BEAT
Use Auto Zero-beat before transmitting to tune in a
CW station. Auto Zero-beat automatically and exactly
matches your transmit frequency with the station you
are receiving. Neglecting to do this will reduce your
chances of being heard by the other station.
1 Tune to the CW signal using the Tuning control.
2 Press [CW T. (AGC OFF)] to start Auto Zero-beat
while CW is selected for the operating mode.
• “CW TUNE” appears.
• Your reception frequency automatically
changes so that the pitch (tone) of the received
signal exactly matches the TX sidetone/ RX
pitch frequency that you have selected. Refer
to “TX SIDETONE/ RX PITCH FREQUENCY”
{below}.
• When matching is completed, “CW TUNE”
disappears.
• If matching is unsuccessful, the previous
frequency is restored.
3 To quit Auto Zero-beat, press [CW T. (AGC OFF)]
or [CLR].
Note:
◆
When using Auto Zero-beat, the matching error is normally
within ±5 Hz.
◆ Auto Zero-beat may fail if the keying speed of the target
station is too slow or if some interference is present.
◆ When the RIT function is ON, only RIT frequencies change
to make the Auto Zero-beat adjustment.
TX SIDETONE/ RX PITCH FREQUENCY
As you send CW, you will hear tones from
the transceiver speaker. These are called TX
(transmission) sidetones. Listening to these tones,
you can monitor what you are transmitting. You may
also use the tones to ensure that your key contacts
are closing, the keyer is functioning, or to practice
sending without actually putting a signal on the air.
RX (reception) pitch refers to the frequency of CW
that you hear after tuning in a CW station.
On this transceiver, the frequency of the sidetone and
RX pitch are equal and selectable. Access Menu No.
34 to select the frequency that is most comfortable for
you. The selectable range is from 300 Hz to 1000 Hz
in steps of 50 Hz (default is 800 Hz).
To change the volume of the TX sidetone, access
Menu No. 4. The selections range from 1 to 9 and
OFF (default is 5).
Note:
◆
The position of the AF control does not affect the volume of
the TX sidetone.
◆ When changing the CW pitch/ side tone, the shift amount
of the receive filter is automatically applied to the CW pitch/
side tone. (In Quick Memory mode, the CW pitch/ side tone
is not revised since the receive filter information stored in the
Quick Memory has priority.)
CARRIER LEVEL
When using AM, CW, or FSK mode, you can adjust
the carrier level.
1 Press and hold [MIC (CAR].
• The current gain level appears on the sub
display.
2 Turn the MULTI/CH control so that the ALC meter
reads within the limits of the ALC zone.
• For AM mode, adjust the MULTI/CH control so
that the ALC meter just begins to indicate.
3 Press and hold [MIC (CAR] again or press [CLR]
to complete the setting.
POWER ON MESSAGE
Each time you switch the transceiver ON,
“KENWOOD” (default) appears on the sub display
for approximately 2 seconds. You can program your
favorite message in place of the default message.
You can enter a message using up to 8 characters.
1 Press [MENU], then press [Q-M.IN]/ [Q-MR] or
turn the MULTI/CH control to access Menu No 87.
2 Press [M.IN]/ [SCAN (SG.SEL)] to begin editing
the message.
3 Move the cursor to the left or right by pressing [Q-
M.IN] or [Q-MR].
4 Press [M.IN]/ [SCAN (SG.SEL)] or turn the
MULTI/CH control to select your desired character.
• You can delete the selected character by
pressing [CL].
5 Repeat steps 3 and 4 to enter the remaining
characters.
6 Press [MENU] to set the entry and exit character
entry mode.
• Press [CLR] at any time to cancel character
entry mode and exit the Menu mode.
