VFOs
and RIT/XIT
• R A T E {21} selects 10 or 50 Hz VFO/RIT tuning. See VFO menu entries, pg. 53.
• F IN E {21} selects 1-Hz steps. C O A R S E selects large steps (MAIN menu, VFO CRS).
• Tap F R E Q E N T {21} to enter frequency in MHz using numeric keypad & decimal point.
Tap return ( ) to complete the entry, or tap F R E Q E N T again to cancel. (Pg. 15.)
• Hold S C A N to start/stop scanning. S C A N must be preceded by a memory recall (pg. 40).
• The R IT and X IT offset knob {17} has LEDs that show -/0/+ offset (pg.16). Tap C L R
{16} to zero the offset. Hold C L R for > 2 sec. to add the offset to VFO A, then zero it.
Transmit,
ATU, and
Antenna
Controls • The TX LED {4} indicates that the K3 is in transmit mode. The ∆f LED turns on if the
RX and TX frequencies are unequal ( S P L IT , R IT / X IT , cross-mode, etc.). (Pg. 13.)
• X M IT {8} is equivalent to PTT {35}. T U N E puts out full CW power in any mode.
• A T U T U N E {8} initiates antenna matching (pg. 22). A T U enables or bypasss the ATU.
• A N T selects ANT 1 or ANT 2 . R X A N T selects main or RX antenna (KXV3).
NB, NR,
and Notch
• Tap N B {12} to enable DSP and I.F. noise blanking. Hold L E V E L to set DSP NB level
(VFO A) and I.F. NB level (VFO B). Fully CCW is OFF in both cases. (Pg. 25.)
• Tap N R {12} to turn on noise reduction (saved per-mode). Hold A D J to tailor noise
reduction for the present band conditions (pg. 25).
• Tap N T C H {12} once to select auto-notch ( NTC H icon), and a second time to select
manual notch (adds icon). Hold M A N to adjust manual notch frequency. (Pg. 25.)
SPLIT,
BSET,
and SUB
• Hold S P L IT {13} to enter split mode (RX on VFO A, TX on VFO B). If VFOs A and B
are on different frequencies in SPLIT mode, the Delta-F LED ( ∆f ) will turn on (pg. 13).
• Hold B S E T {13} to adjust VFO B / sub RX settings independently of VFO A (pg. 37).
• Tap S U B {20} to turn on the sub receiver (pg. 37). VFO B controls its frequency.
• Hold S U B {20} to link the two VFOs (VFO A is then the master). A 2-second hold of
S U B engages diversity mode (pg. 38). SPLIT operation is possible in diversity mode.
Memories,
Messages, and
DVR
• To store a frequency memory, tap V M {14}, then: tap M 1 - M 4 {15} to save a per-band
quick memory; or tap 0 - 9 to save a general-purpose quick memory; or rotate VFO A to
select from memories 0-99, then tap V M again to save. Tap M V to recall. (Pg. 16.)
• R E C and M 1 - M 4 {15} are also used to record & play voice/CW/DATA messages. The
KDVR3 option is required for voice messages and A F R E C / A F P L A Y (pg. 29).
Menus and
Switch Macros
• M E N U & C O N F IG {8} access the MAIN and CONFIG menus. VFO B selects entries;
VFO A changes parameters. In general, CONFIG menu entries are used less often.
• Tapping D IS P {8} within menus shows information about each entry on VFO B (pg 52).
• Menu entries can be assigned to programmable switches P F 1 , P F 2 {16} and M 1 - M 4 {15}
(pg 52). These switches can also execute often-used macros like “SPLIT, A>B, move VFO
B up 5,” with a single tap or hold. See the K3 Programmer’s Reference for examples.
Other
Features
• RX and TX EQ (MAIN menu) provide 8 bands of receive/transmit equalization (pg. 35).
• Tap
A F X {18} to enable the selected audio effect (see CONFIG:AFX MD, pg. 52).
• Tap D IS P {8} and use VFO B to show time, supply voltage, etc. on VFO B (pg. 36).
• The ALARM function (MAIN:ALARM menu entry) can be used to remind you about a
contest, net, or QSO schedule, and can even turn the K3 on at alarm time (pg. 36).
• The KIO3 module provides a rich set of AF {33} and digital {32} I/O (pg. 17).
