If set to , switch presses generate audible feedback tones. If set to
O N
Morse code characters are generated on any control activation at
minute. (The full list of Morse code control characters, as well as a text-only
panel description for blind operators, can be found on our KX3 web page.)
Switch tone volume is the same as CW sidetone volume. It must be adjusted in
CW mode, using
M O N
Pitch of switch tones and Morse characters: In general, a low-to-high tone pair
(or high-pitched Morse) is generated when a switch function is turned on, and
high-to-low (or low-pitched Morse) when it is turned off. Following
Some switches do not generate tones because they might interfere with received
or transmitted audio.

Transmit audio graphic equalizer (voice modes only). Functions the same as RX
EQ, above. TX EQ can be adjusted during transmit. SSB TX EQ is separate
from TX EQ for other voice modes. Not applicable to CW or DATA modes.

Shows transmit gain constant for the present band and power setting. Two gain
constants are used: one for PWR settings of 5.0 watts or less, and the other for
PWR settings of 5.1 watts or higher. The gain constants are calibrated whenever

Transmit ALC can be turned off for 2-tone testing or other purposes by tapping
while in this menu entry. (This is NOT necessary for any operational

purpose. In DATA modes, ALC is already optimized for low distortion.) When
ALC is turned off, a (-) sign is added to the parameter, e.g.
asterisk is added to the

as a fine power adjustment, and its effect should be observed with an external
instrument.
The TX noise gate can be used to suppress transmitted audio below a certain
level, e.g. that of an amplifier fan. Tap
the noise gate on/off. Use VFO A to set the desired threshold. Since there's no
visual indication that transmit audio is below the threshold, you should adjust it
using the transmit voice monitor (MON), ideally while using headphones. Set the
threshold high enough to cut off transmit audio due to local noise, but not so high
that it causes your voice to drop out too frequently.
Used at the factory to null transmit opposite sideband. See Transmit Sideband,
