Specifications

6
VFOs
and RIT/XIT
 R ATE {21} selects 10 or 50 Hz VFO/RIT tuning. See VFO menu entries, pg. 52.
 F IN E {21} selects 1-Hz steps. C OAR SE selects large steps (MAIN menu, VFO CRS).
 Tap F R EQ ENT {21}to enter frequency in MHz using numeric keypad & decimal point.
Tap return ( ) to complete the entry, or tap F R EQ EN T again to cancel. (Pg. 15.)
 Hold SC AN to start/stop scanning. SC AN must be preceded by a memory recall (pg. 39).
 The R I T and XIT offset knob {17} has LEDs that show -/0/+ offset (pg.16). Tap CLR
{16}to zerothe offset. Hold CL 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 intransmit mode. The ∆f LED turns on if the
RX andTX frequencies are unequal (SPL I T, RIT/XI T , cross-mode, etc.). (Pg. 13.)
 XMI T {8} is equivalent to PTT {35}. TU N E puts out full CW power in any mode.
 ATU TU N E {8} initiates antenna matching (pg. 22). ATU enables or bypasss the ATU.
 ANT selects AN T1 or ANT2. RX AN T selects main or RX antenna (KXV3).
NB, NR,
and Notch
 Tap NB {12}to enable DSP and I.F. noise blanking. Hold L EVEL 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. Hold ADJ to tailor noise reduction for the
present band conditions (pg. 25).
 Tap N TC H {12} once to select auto-notch (NTCH icon), and a secondtime to select
manual notch (adds icon). Hold MAN to adjust manual notch frequency. (Pg. 25.)
SPLIT,
BSET,
and SUB
 Hold SPL I T {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 BSET {13} to adjust VFO B / sub RX settings independently of VFO A (pg. 37).
 Tap SU B {20} to turn on the sub receiver (pg. 37). VFO B controls its frequency.
 Hold SUB {20} to link the two VFOs (VFO A is then the master). This allows diversity
receive with main and sub if two different antennas are used (pg. 37).
Memories,
Messages, and
DVR
 To store a frequency memory, tap V M {14}, then: tap M1 -M4 {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, thentap V M again to save. Tap M V to recall. (Pg. 16.)
 R EC and M1 -M4 {15} are also used to record & play voice/CW/DATA messages. The
KDVR3 option is required for voice messages and AF R EC / AF PL AY (pg. 29).
Menus  MEN U & C ON FI G {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 DI SP {8} within menus shows information about each entry on VFO B (pg51).
 Up to 10 menu entries can be assignedto programmable function switches. PF1 and PF 2
{16} are dedicated programmable functions. Any of M1 -M4 {15} can be used as Tap
and/or Hold programmable functions if they’re not being used for message play (pg 51).
Other
Features
 RX and TX EQ (MAIN menu) provide 8 bands of receive/transmit equalization (pg. 35).
 Tap AF X {18}to enable the selected audio effect (see CONFIG:AFX MD, pg. 51).
 Tap D I SP {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 eventurn 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).
