 Select FM mode: Tap

MODE

until

appears on the right hand edge of the LCD.

 Set Voice Monitor Level: If you wish to monitor your voice in the phones or speaker while

transmitting, hold

M O N

to switch the VFO B display to

MON

and then turn the knob to set the

level of the audio between

and

. High levels may result in distortion or feedback. Suggest you

start with

MON 5

or less as shown on the LCD.

MON 0

turns the monitor function off.

 Set Display to CMP/ALC: If the bargraph indicates SWR/RF tap the

KEYER/MIC

control to

switch the display to CMP/ALC.

Be sure you have a suitable antenna or dummy load connected to the SMA antenna

connector when making the following transmitter adjustments.

 Set Microphone Gain Level: Press the microphone PTT switch and, while speaking normally into

the microphone, adjust the

KEYER/MIC

control for 5 or 6 bars indicated on the LCD ALC

display as shown in Figure 1.

 Set RF Power Output Level: Exit transmit mode, and hold

PWR

. The output power setting

will be displayed in the VFO B area of the LCD. Adjust the knob for the desired output power, and
then tap the knob to exit the power adjustment.

 Frequency Deviation: The KX3 is programmed with commonly used values of FM frequency

deviation (3.5 kHz for voice and 0.36 kHz for PL tone used by repeaters). If different values are
used in your area, hold

ME NU

and use the VFO knob to locate FM DEV on the LCD. This

setting is locked to avoid accidental changes. Unlock the control by holding

KHZ

for several

seconds until the padlock symbol to the right of the deviation value shown on the LCD disappears,
and then set the desired deviation with the VFO knob. If needed, display and change the PL tone
by tapping the

switch, and then unlock and change the PL deviation in the same manner. Tap

M E N U

to exit the menu.

Do not attempt to increase your “talk power” by increasing the deviation. Optimum

results require that your deviation match the deviation used by the other station. See
Troubleshooting on page 10 for more information.

 Simplex or Repeater Operation: Setting up your KX3-2M/4M for repeater operation is described

below. For Simplex operation, hold

AL T

repeatedly as needed to display

SIMPLEX

in the VFO B

area of the LCD.

Repeater Operation

Repeater operation requires transmitting on the repeater’s input frequency and receiving on the repeater’s
output frequency. Also, many repeaters require a sub-audible tone transmitted with the voice audio or a
short burst of tone at 1750 Hz to activate the repeater transmitter. The KX3 can be programmed with the
required transmit and receive frequency pairs and tones, selected from a list of standard tone frequencies, to
make setting up for any repeater or simplex channel a simple matter of recalling a memory location.

Frequency Memory Editor

Although you can enter all the necessary information using just the KX3 front panel controls (see Manual
Frequency Entry on page 7), the easiest way to program your KX3 for repeater operation is to use the K3
Frequency Editor program available from the Elecraft web site at:

http://www.elecraft.com/K3/FreqMemEdit/K3_Freq_Mem_Editor.htm

Note that the editor refers to the Elecraft K3 transceiver throughout. The same

editor is used with the KX3.
