impedance. Allow heatsink to cool. Reduce power if necessary. Make sure the CONFIG:PA TEMP menu
entry is calibrated (allow heatsink to cool to room temperature, then compare menu reading to actual).

ALC O FF
is displayed on VFO A during transmit
:
Set CONFIG:TX ALC to
O N
. ALC should only be
turned off during band-pass filter alignment ( do not adjust filte rs without consulting Ele craft support ).

Can’ t t rans mi t i n CW mode:
(1) Make sure the key or keyer paddle is plugged into the correct jack.
(2) You must have VOX selected (
V OX
icon on) in order to use hit-the-key CW. (3) You may be in
S PL I T
mode, with VFO B set for a voice or data mode. Tap
A/ B
or use
B S E T
to che
ck VFO B’ s mode.

Ke y clicks in QSK CW mode with an external amplifie r: . T his may be due to a slow amplifier relay (use
CONFIG:TX DLY
) or incorrect application of external ALC (see
CONFIG:EXT ALC
and pg. 27).

Can’ t us e t he mi c i n voi c e modes:
You may be in
S PL I T
mode, with VFO B set for CW or data mode
rather than a voice mode. T ap
A/ B
or use
B S E T
t o c hec k VFO B’ s mode.

No powe r output: You may ha
ve r ou t ed RF t hr ough t he KXV3’ s XVTR I N
/OUT jacks, either by switching
to a transverter band, or by setting
CONFIG:KXV3
to TE S T . Another possibility is that power has not been
calibrated on the present band (pg. 48).

Relay heard switching during keying: If this happens only above a certain power level, transmit signal
leakage may be activating the carrier-operated-relay circuitry on either the KXV3 module (RF I/O) or the
KRX3 (sub receiver). You must either improve isolation between transmit and receive antennas, or decrease
output power. If a relay switches during keying even at very low power levels, it could be due to: (1) SPLIT
operation with different bands and/or modes, or the receive VFO tuned outside any ham band; (2) VFO A is
tuned close to a point where a relay switches between transmit and receive due to incorrect VCO calibration
(re-run VCO CAL using the latest firmware, then tune across the affected band in receive mode to make
sure no relay switching occurs).


HI RFI warning : A high-
power t r ans mi t t er may be c oupl i ng i nt o t he K3’ s ant enna i n r ecei ve mode. The
warning occurs when the ANT1 or 2 input signal exceeds about 1 to 2 W. You can disable the warning (set
CONFIG:RFI DET to
O FF
), but eliminating the over-coupling will ensure no damage to K3 components.

No re ceive d signal: Possibilities include (1) receiver being squelched (if RF/SQL controls are assigned to
squelch via
CONFIG:SQ MAIN
or
SQ SUB
, rotate squelch controls fully counter-clockwise); (2) RF
GAIN too low (set RF gain controls fully clockwise); (3) filter bandwidth too narrow (set WIDT H or tap
X F I L
, and also verify filter configuration settings); (4) switching to an open receive antenna on the KXV3
(RX ANT IN); (5) switching the KAT 3 to an open antenna jack; (6)
CONFIG:REF CAL
parameter not
adjusted properly; (7) CONFIG:KXV3 may be set to T EST, which routes all RF through the XVT R
IN/OUT jacks.

Re ceive d signal le ve l too low: (1) T ry setting CONFIG:AF GAIN to
HI
; (2) check headphone and speaker
plugs and cables; (3) make sure that CONFIG:RX EQ settings are either flat or have not been set for a large
amount of cut; (4) recheck all filter configuration settings, particularly the
CONFIG:FLx BW
,
FLx GN
, and
FLx FRQ
menu entries; (5) verify that
CONFIG:REF CAL
is properly adjusted; (6) make sure RF GAIN is
set to maximum.
