Band and Mode Selection
T ap either end of the
B AN D
switch to select the
desired ham band (160 through 6 meters). You can
also go directly to any desired frequency using
direct frequency entry (pg. 15), or recall a
frequency memory (pg. 16).
T ap either end of
MO D E
to select the operating
mode. Hold
AL T
to select an alternate mode, if
required. This include CW RE V (pg. 30), DATA
RE V (pg. 31), AM -S (synchronous detection, pg.
29), and
FM + / -
(FM repeater split, pg. 29).
Antenna Selection and Matching
ATU (KA T3)
If you have the KAT3 antenna tuner installed, you
can select
ANT1
or
ANT2
by tapping
AN T
.
Hold
ATU
to select
AUTO
(autotune enabled) or
BY P AS S . If the ATU icon is on, the antenna can
be matched for best SWR by tapping
ATU TU N E
.
AT U settings are saved per-band and per-antenna.
T apping
ATU TU N E
a second time within 5
seconds of a match attempt will retry using a more
extensive search. This may improve the match
when using high-SWR or narrow-band loads.
Holding
AN T
allows names to be assigned to
ant ennas ( e. g. , ‘
Y AGI
’
). T hese will be flashed each
time you switch antennas. When editing names,
VFO B selects the character position to change;
VFO A cycles through available characters. Setting
t he f i r s t c har ac t er t o “—” di s abl es name di s pl ay.
RX Antenna (KXV3)
With the KXV3 installed, you can tap
R X
to select
a receive-only antenna (RX ANT IN). The K3 also
has an RX ANT OUT jack for use with in-line
filters, the PR6 6-m preamp, etc.; see pg. 38.
Sub Re ceive r Antenna (KRX3)
If the sub receiver is turned on (by tapping
S UB
),
its antenna selection can be changed using
B S E T
.
While in BSET , tap
AN T
to switch between M AI N
(sharing the main antenna) and
AUX
(using the
s ub’ s AUX RF
input). For further details on sub
receiver antennas, see pg. 37 and pg. 40.
Using the VFOs
VFO A is both the main receive and transmit
frequency, except during SPLIT, in which case
VFO B controls the transmit frequency (pg.36).
VFO B also controls the sub receiver (pg. 37).
T ap
R ATE
to select 10 / 50 Hz per step. The faster
rate can be changed using
CONFIG:VFO FST
.
The number of counts (or steps) per VFO knob turn
can be changed using
CONFIG:VFO CTS .
T apping
R ATE
briefly flashes either the 10-Hz or
100-Hz digit to indicate slow or fast tuning.
For 1-Hz steps, tap
FI N E
; for wider steps, use
C O AR S E
(see
CONFIG:VFO CRS
). When
F IN E
is in effect, a 1-Hz digit will appear in the VFO A
display. When
C O AR S E
is in effect, the 10-Hz
digit is not shown.
T ap
A B

VFO B. T apping
A B
a second time within 2
s econds al s o c opi es VFO A’ s mode, f i l t er , a nd ot he r
settings to VFO B.
A / B
exchanges VFO A and B and their settings.
(Also see
CONFIG:VFO B->A
.) Pressing
R E V
exchanges the VFOs for as long as you hold it in.
VFO B and the sub receiver can be set up directly
by holding
B S E T
. While
BS E T
is in effect, all
icons and VFO-related controls apply to VFO B
(and to the sub receiver, if turned on; see pg. 37).
Holding
S U B
links/unlinks the VFOs, whether or
not a sub receiver is installed or turned on (pg. 37).
RIT and XIT
The RIT /XIT offset control, at the far right, sets the
offset for
RI T
and
X I T
. The offset is shown on the
VFO B display as you adjust the control. T hree
LEDs show whether the offset is 0, (-) or (+).
T ap
C LR
to zero the RIT /XIT offset. Tapping it a
second time restores the offset.
To copy the present RIT offset to VFO A, hold
C LR
for 2 seconds. VFO A will be moved to the
new frequency before the offset is zeroed.
If RIT and XIT are both turned off, the RIT
offset can coarse-tune VFO A (
CONFIG: VFO
CRS ). For example, you can select 5, 9, or 10 kHz
steps in AM mode.
