CW Mode
CW Normal and Reverse
Select CW mode by tapping either end of MODE .
Hold AL T to alternate between CW normal and
CW reverse (REV icon). CW reverse differs from
CW normal only in receive mode, using the upper
ratherthan lower sideband.
If you SPOT (or auto-spot) a CW signal (pg. 34),
then switch between CW normal and reverse, the
pitch of the received signal should stay the same.
Basic CW-Mode Controls
In CW mode, MON setsthe sidetone volume.
Hold PITCH to adjust the sidetone pitch. The peak
in response of all crystal filters will trackthe
sidetone pitch; no filter adjustments are needed.
Hold QSK to select full break-in (QSK icon on) or
semi break-in operation.
VOX must be turned on in CW mode to enable
both full and semi break-in operation. If PTT is
selected (VOX icon off),transmit must be activated
using PTT or by tapping XMIT.
QSK, or full break-in, allows youto better keep
track of on-frequency activity even while you’re
sending. It allows others to “break” your CW
transmission by sending one or two characters.
With semi break-in selected (QSK icon off), the
K3 returns to receive mode after a time delay you
set using D EL AY. This is a compromise between
full break-in and fully manual operation using PTT
or XMI T .
Hold TEST to place the K3 into TEST mode. This
allows you to send CW without transmitting a
signal on the air. This is helpful for practicing your
sending or for off-the-air checkingof pre-recorded
CW messages.
CW-Mode Menu Entries
Configuration menu entries are provided to set up
CW iambic keyingmode (CW IAMB), paddle
normal/reverse selection (CW PADL), and keying
weight (CW WGHT).
SPOT and Auto-Spot
When calling another station, you should try to
match your frequencyto theirs. To facilitate this,
the K3 provides both manual and automatic
spotting for use with CW and DATA signals. See
Tuning Aids: CWT and SPOT (pg. 34).
CW Text Decode/Display
The K3 can decode transmitted and received CW
signals, displaying the text on VFO B (pg. 33). This
feature is especially useful when you’re learning
CW, or if someone who doesn’t know CW is
looking over your shoulder while you make CW
QSOs. It’s also indispensable for CW-to-DATA
operation (pg. 34).
Dual Passband CW Filtering (DUAL PB)
Turning on DUAL PB in CW mode allows youto
listen to a narrow filter bandwidth (the “focus”), set
within a wider, attenuated filter bandwidth (the
“context”). See pg. 35.
CW Message Record/Play
Messages can only be recorded using the
internal keyer, not a handkey or external keyer.
If text decode is on (pg. 33), CW text sent
using the internal keyer is shown on VFO B (pg.
33). Use TEST to check messages off-air (pg. 13).
There are 8 message buffers, arranged in two banks
of 4. Buffershold250 characterseach. To switch
banks, hold R EC .
Message Record: To start recording, tap R EC ,
then M1 - M4 . The remaining buffer space will be
displayed as you send. Tap R EC again to stop.
Message Play: Tap M1 – M4 to play.To cancel,
tap REC . You can also hit the keyer paddle, key,
or any switch besides M1 –M4 to cancel play.
Auto-Repeat:To auto-repeat a message, Hold
(rather than tap) M1 –M4 . MAIN:MSG RPT sets
the message repeat interval (1 to 255 seconds).
Chaining: Tapping M1 –M4 during playback
chains another message onto the message being
played. Holding a message switch during playback
chains a repeating message.
