Connections
Connect a power supply to the DC input jack
{26}
(see Specifications, pg. 8).
On the K3/100, a circuit breaker is provided on the fan panel for the 100-W stage
{30}
.
You can power an accessory device from the switched DC output jack
{38}
(0.5 A max).
Connect an antenna to ANT1
{29}
. If you have an ATU installed (pg. 22), you can connect
a second antenna to ANT2
{28}
. If the KXV3 is installed, you can connect a separate RX
antenna to RX ANT IN
{34}
. The AUX RF connector
{27}
is optional; see pg. 17.
The Basics
Press

Functions:
Tapping
briefly activates the function labeled
on
a switch.
Holding
for about 1/2 second activates the function labeled
below
a switch.
T ap either end of

controls are discussed on pg. 37.
The large knob
{22}
controls VFO A (upper display,
{10}
). The medium knob
{19}
controls VFO B (lower display,
{11}
). VFO A is main RX/T X except in SPLIT (pg. 36).
CM P
/
P WR
is one of four
multifunction controls {24}
. Each has two primary
functions, indicated by green LEDs. The knob has a built-in switch;
tap
it to select either
CM P
(compression level) or
P WR
(power output).
Hold
the knob in to access its
secondary function,
M O N
itor level. Tap again to restore the primary function.
Filter
Controls
Rotate the
SHIFT / LOCUT
and
HICUT / WIDTH
controls
{23}
to adjust the filter
passband. Crystal filters
FL1
-
FL5
are automatically selected as you change the
bandwidth. T ap either knob to alternate between shift/width and hicut/locut.
Hold
SHIFT / LOCUT
to
NO RM
alize the bandwidth (e.g., 400 Hz CW, 2.8 kHz SSB).
Hold
HICUT / WIDTH
to alternate between two filter setups,
I
and
II
(per-mode).
T ap
XF IL
{13}
to select crystal filters manually; this also removes any passband shift.
Voice Modes
{1}
Hold
ME TE R
{8}
to see
CM P
/
ALC
levels. While talking, set
MIC
{25}
for 4-7 bars
of ALC, and
CMP
for the desired compression. Then return to
S WR
/
P WR
(pg. 28).
O ptional:
Hold
TE S T
{6}
for
TX TEST
mode; allows off-air TX adjustments (pg. 13).
Hold
CMP / PWR
{24}
to set speech
MO N
itor level; tap to return to
CM P
/
P WR
.
Hold
V O X
{7}
to select PTT or
V OX
. Hold
SPEED / MIC
to set VOX
DE LAY
.
Details:
VOX, pg. 29; T X EQ, pg. 35;
MIC SEL
, pg. 51; SSB/AM/FM, pg. 28.
CW Mode
{36}
SPEED
{25}
sets the CW keyer speed. Hold this knob to set semi-break-in
DE LAY
.
Hold
Q S K
{7}
to select full break-in (
Q S K
icon on) or semi-break-in. (Pg. 30.)
Hold
P I TCH
{18}
to set sidetone pitch. Hold
CMP / PWR
to set sidetone
MO N
level.
T ap
C W T
{18}
for tuning aid
{9}
(pg. 34). With
CWT
on,
S P O T
auto-tunes (pg. 30).
To select CW text decode/display mode, hold
TE X T D E C
{18}
; rotate VFO B (pg. 30).
CW keying is converted to DATA in
FS K D
and
PS K D
modes (below and pg. 34).
Hold
DU AL P B
{13}
to turn CW dual-passband filter (pg. 30).
Data Modes
{31}
T ap
MO D E
{6}
until you see the
DATA
icon turn on (see Data Modes, pg. 31).
Hold
D AT A MD
{18}
. Use VFO B to select from:
DATA A
(PSK31 & other
soundcard-based modes),
AFS K A
(soundcard-based RTT Y),
FS K D
(RTT Y via data
input or keyer), or
P S K D
(PSK via data input or keyer). VFO A selects data baud rate
for internal encoder/decoder, if applicable.
DU AL P B
turns on RTTY filter (DT F, pg. 32).
Hold
P I TCH
{18}
to select mark tone and shift (for encoder/decoder and RTT Y filter).
Hold
