Transmit Crystal Filter Selection (Per-Mode)
This step applies only to filters on the RF board.
• Select CW mode by tapping M O D E .
• Use VFO B to find the FLTX CW menu entry.
• Rotate VFO A to select a CW transmit filter
(2.7 or 2.8 kHz). Note: Key clicks may result if
a narrower filter is selected for CW transmit.
• Tap M O D E to select LSB or US B . The menu
entry will become FLTX SB.
• Select the filter to be used during SSB and
DATA transmit (2.7 or 2.8 kHz).
• If applicable, select a 6-kHz filter for AM and
ESSB (FLTX AM), and 13.0 kHz for FM
(FLTX FM).
If you’re using a 2.7-kHz 5-pole filter for SSB
transmit, you can optionally fine-tune its FLx FRQ
parameter to equalize LSB and USB transmit
characteristics. Monitor with a separate receiver and
use headphones, or have another station listen.
Option Module Enables
K3 options can be installed at any time.
Once an option has been installed, use the
associated CONFIG menu entry to enable it (see
below). Then turn the K3 off for 5 seconds, and
back on. This allows the K3 to find and test the
module.
• KAT3 ATU module: set KAT3 to BYP .
• KBPF3 general-coverage band-pass filter
module: set KBPF3 to NOR (if you’re
installing a KBPF3 on the sub receiver, tap
S U B while in the menu entry).
• KXV3 RF I/O module: set KXV3 to NOR .
• KRX3 sub receiver: set KRX3 to match your
selected wiring for the sub receiver’s AUX
antenna:
ANT =ATU (KAT3) or ANT =BNC
(AUX RF jack, rear panel). For details on sub
receiver antennas, see pg. 37. You may also
need to set up crystal filters for the sub receiver.
• KDVR3 voice recorder: set KDVR3 to NOR .
• KPA3 amplifier module: set the KPA3 menu
entry to PA NOR . See menu entry listings for
information on other settings.
Miscellaneous Setup
We suggest setting up at least the menu entries
below. You may wish to review the other menu
entries as well, starting on pg. 52.
Mic Gain / Bias
MAIN:MIC SEL is used to select either the front- or
rear-panel mic, or
LIN E IN . If a mic is selected,
you can also tap 1 to select L o or H i mic gain
range, and tap 2 to toggle mic bias on/off. See pg.
13 for Elecraft mic bias recommendations.
AF Gain Range
CONFIG:AF GAIN specifies LO or HI AF gain
range. The default is HI .
Time and Date
CONFIG:TIME sets the 24-hour real-time-clock
(RTC). Tap
1 / 2 / 3 to adjust HH/MM/SS using
VFO A. K3Utility can also be used to set the time.
CONFIG:DATE MD selects US ( MM. DD.YY ). or
EU ( DD. MM.YY ) date format using VFO A.
CONFIG:DATE is used to set the date. Tap 1 / 2 /
3 to adjust MM/DD/YY or DD/MM/YY.
VFO Setup
Several CONFIG menu entries are provided to
control VFO behavior:
• VFO CRS sets up the C O A R S E tuning
increment in kHz (separate for each mode). Tap
1 to turn rounding on/off.
• VFO CTS specifies the number of counts per
knob turn (VFO A and B): 100 , 200 , or 400
• VFO FST selects the normal VFO fast tuning
rate ( 20 or 50 Hz)
• VFO IND, if set to YES , allows VFO B to be
set to a different band than VFO A.
