LEDs
TX [Red] Turns on in transmit mode.
∆ F [Yellow] The Delta-F LED turns on if
transmit and receive frequencies or modes are
different due to the use of SPLIT, RIT, or XIT.
[Green] Eight LEDs show which functions are
in effect for the Multifunction Controls (pg. 14).
(-) (+ ) RIT/XIT OFFSET If the
offset control is centered, or you tap C L R , the
green LED turns on (offset = 0). Otherwise, the
yellow (-) or (+) LED will be on, indicating the
direction of the offset. See
R IT , X IT , and C L R .
Front Panel Connectors
PHONES You can use either mono or stereo
headphones at either the front- or rear-panel
headphone jack. Also see
A F X (pg. 35).
MIC An Elecraft MH2, MD2, Proset-K2, or other
compatible mic can be used (see pinout below). To
select the front- or rear-panel mic, and to turn bias
on/off, use the MAIN:MIC SEL menu entry.
Bias must be turned on for electret mics (e.g. MH2,
MD2, Proset). It must be off for dynamic mics (e.g.
Heil mics using HC4 or HC5 elements).

FP ACC This connector (RJ-45, 6 pins) is located
on the bottom of the transceiver, near the VFO B
knob. It is used with accessory devices.
Primary Controls
B A N D Tap left/right end to move among ham
bands. CONFIG:BND MAP disables bands. For
“quick” band switching, see CONFIG:MEM 0-9.
V O X Selects voice-operated or CW keying-
operated transmit ( VOX icon on), or PTT ( VOX
icon off). Also see D E L A Y (pg. 30) and CW
VOX auto-off control (CONFIG:CW WGHT).
Q S K Selects either full break-in ( QSK icon on) or
semi break-in keying, if VOX is selected in CW
mode. Also see
D E L A Y (pg.30).
M O D E Tap the left or right end of this switch to
select the operating mode. When DAT A is selected,
the D A T A M D switch is used to specify DATA-A,
AFSK A, FSK D, or PSK D (pg. 31).
A L T In LSB mode, switches to USB (and vice-
versa). Also selects alternate modes, including:
CW REV , DAT A REV , and AM- S (pg. 29). In
FM mode, selects + / - or simplex (pg. 29).
T E S T Selects TX TEST ( TX LCD icon flashing);
allows key/mic test without actually transmitting.
P O WE R Turns the K3 on or off. Note: To ensure
correct save of operating parameters, turn the
K3 off before turning the power supply off.
M E N U Displays MAIN menu (pg. 21).
C O N F IG Displays the CONFIG menu (pg. 21).
X M IT Manually-operated transmit. Places the K3
into transmit mode (same as PTT, pg. 26).
T U N E Puts out a carrier at the present power level.
Also TUNE Power Level (pg. 27).
R X A N T Enables the receive antenna (pg. 22). If
the sub RX is on, holding R X A N T alternates
between the sub’s MAI N / AUX antennas (pg. 37).
D IS P Shows an alternate display on VFO B, such
as time, date, voltage, etc. (pg. 36).
M E T E R Selects voice transmit bar graph modes:
SWR and RF , or CMP and ALC (pg. 28).
A T U T U N E Matches the antenna (transmitting at
up to 10 W) using the KAT3 ATU (pg. 22).
A T U Puts the ATU into normal mode ( ATU icon
on) or bypass mode (pg. 22).
A N T Selects ANT 1 or 2 . In BSET mode with the
sub receiver on, selects MAI N or AUX antenna for
the sub receiver (pg. 37).
