Voice Modes (SSB, AM, FM)
Basic Voice-Mode Setup
To avoid transmitting on the air during this
procedure, you can set PW R to 0.0 watts.
Choose a mode: Tap MO DE to select
LSB /USB , A M, or FM mode. In SSB modes,
AL T alternates between LSB and USB .
Hold
MO N to set the voice monitor level. A
setting of about 5 is a good starting point.
Tap C MP and set it to 0 for now using the knob
above. Tap it again to exit the CMP display.
Enable transmit: Tap X MI T or hold in the
mic’s PTT switch.
Adjust mic gain level: While speaking into the
mic, adjust KE Y E R/ MIC (mic gain). This
will automatically turn on the transmit CMP
and ALC bar graphs. While speaking, adjust
mic gain for about 5 ALC bars (see below).
Set up speech compression (optional): To use
speech compression, tap C MP and adjust the
level using the knob above the switch. The
CMP scale (see above), shows approximate
compression level. Low settings (1 to 10) will
preserve a more natural voice sound.
Set the power level: Exit transmit mode and
adjust P W R to the desired level.
Voice Mode VOX Setup
VO X selects push-to-talk (PTT) or voice-operated
(VOX) transmit (VO X icon on). VOX hold time is
set with DL Y (pg. 14).
MENU:VOX GN (VOX gain) should be set to
trigger at normal speech level, but not in response
to incidental noise. Start with low settings (10-20).
MENU:VOX INH (VOX inhibit, or anti-vox) can
prevent speaker audio from triggering VOX. With
the mic closer to the speaker than normal, increase
ANTIVOX until the KX3 doesn’t switch to TX
mode when listening to a strong signal.
Transmit Metering in Voice Modes
Normally, the SWR/RF bar graph is active during
transmit in all modes. In voice modes, you can
switch to the CMP / A LC bar graphs by tapping
KE Y E R / MIC . This also occurs automatically if you
adjust mic gain or speech compression.
FM Operation
If you don’t use FM mode, you can disable it by
setting MENU:FM MODE to OFF .
To setup for repeater use:
Hold AL T one or more times to select simplex,
TX up (+ icon), or TX down (- icon). If an
offset is in effect, R EV swaps RX/TX
frequencies and offset direction.
Set up the required repeater offset using
MENU:RPT OFS.
Select a coarse VFO step size for FM mode
using MENU:VFO CRS.
If PL tone encode is required, hold PIT CH to
turn it on, and rotate the knob above this switch
to select the tone frequency. Hold P IT C H again
to turn PL tone encode off. When tone encode
is on, a T appears in the mode icon area.
To change the FM deviation level for voice and
PL tones, see MENU:FM DEV.
Squelch: Tap A F / R F -S Q L , then rotate the
knob to select the desired squelch threshold. (In
all other modes, the alternate knob function is
RF gain.) Tap the knob again to return to the
AF gain function.
AM Operation
AM receive on the KX3 uses traditional envelope
detection. You can also listen to AM signals using
LSB or USB modes, which may provide better copy
during fading conditions.
During AM transmit, it is normal for the RF bar
graph to indicate about one-third to one-half the
power level set by the power control. Transmit
efficiency is much lower in AM mode than SSB as
discussed on pg. 10.
To disable AM mode, set MENU:AM MODE
to OFF .
